(90) points ill give brainly immideatly but gotta be right -------- Maria and her parents are hiking in the mountains. During one hike, Maria monitored their changing elevation and displayed it in the graph below. Which of the following BEST describes a functional relationship shown in the graph? A Maria's elevation remained constant for two hours. B Maria's elevation decreased between 1:00 and 3:00. C Maria's elevation increased between 9:00 and 12:00. D Maria spent more time decreasing her elevation than increasing her elevation.
Answer:
(C) Maria's elevation increased between 9:00 and 12:00
Step-by-step explanation:
Looking at the graph, we can test each statement.
For A, it says Maria's elevation remained constant for 2 hours. Looking at the graph, we can see that it remained constant for just one hour, so this is eliminated.
For B, Maria's elevation decreased between 1:00 and 3:00, we can see that while x is between 1:00 and 3:00, the y is decreasing, meaning this statement is false - this is eliminated.
For C, Maria's elevation increased between 9:00 and 12:00, we can see that while x is between 9:00 and 12:00, the graph is increasing - which means this is correct.
For D, Maria spent more time decreasing her elevation than increasing, we can count how many hours were spent doing each. Comparing the x-axis, we can see that Maria spent 5 hours increasing and 3 hours decreasing, meaning that Maria spent more time INCREASING than decreasing, making this statement false.
Hope this helped!

Answer:
a. 1120 is the area b. max # of ppl is 80
Step-by-step explanation:
a. Area= Length* width = 28 * 40 = 1120
(8,10) and (8,38) have 28 units between them
(8,10) and (48,10) have 40 units between them
b. Since the area is 1120 and they say that only one person is allowed per 14 square feet, you would divide 1120 by 14 to get 80 people
If each coordinate equals 1 foot then:
(8,10) to (48,10) is 40 feet (48-8)
(8,10) to (8,38) is 28 feet (38-10)
so now you got length 40 and width 28
40 x 28 = 1120
a. 1120ft^2
b. 1120 / 14 = 80
Determine if the two triangles shown are similar. If so, write the similarity statement. options:
A) ΔWUV ∼ ΔFGH
B) ΔUVW ∼ ΔFGH
C) Impossible to determine.
D) The triangles are not similar.
Answer:
B
Step-by-step explanation:
∠ U = ∠ F = 76° thus are congruent
Consider the ratios of corresponding sides
[tex]\frac{UW}{FH}[/tex] = [tex]\frac{9}{21}[/tex] = [tex]\frac{3}{7}[/tex]
[tex]\frac{UV}{FG}[/tex] = [tex]\frac{18}{42}[/tex] = [tex]\frac{3}{7}[/tex]
Thus Δ UVW ~ Δ FGH by the SAS postulate
Yes the given two triangles are similar.
The similarity statement is B) ΔUVW ∼ ΔFGH
What do we mean by similar triangles ?
The triangles that have similar shape but the sizes of the triangles may be different, are called similar triangles.
Are the given triangles similar or not ?Here, in the given triangles,
∠U = ∠F = 76°
Therefore they are congruent.
The ratio of corresponding sides, [tex]\frac{UW}{FH} =\frac{9}{21} = \frac{3}{7}[/tex]
Again the ratio of corresponding sides, [tex]\frac{UV}{FG}=\frac{18}{42}=\frac{3}{7}[/tex]
Thus, ΔUVW ∼ ΔFGH by SAS rule of similarity.

Determine the measure of the central angle for a regular
7-sided polygon, round answers to one decimal place.
Select one:
a. 25.7°
b. 51.4°
c. 61.4°
d. 62.2°
Answer:
B
Step-by-step explanation:
If the figure is regular, then everyone of the central angles are equal. They add up to 360 degrees.
x + x + x + x + x + x + x = 360 Combine
7x = 360 Divide by 7
x = 360/7
x = 51.43
An online retailer is offering a 30% savings on your total order. You decide to purchase a pair of pants for $82, two shirts for $53 each, and a pair of shoes for $120. A sales tax of 8.25% will be added to your order. What is the final price including all discounts and taxes for the clothing? Round your answer to the nearest cent
Answer:
$233.39
Step-by-step explanation:
Pants = $82, 2 Shirts = $53 * 2, Shoes = $120
Add all these values up to find the total cost of your order excluding tax.
82 + 53(2) + 120 = 308
Next find the price w/ tax. Multiply 308 by 8.25%, or 0.0825.
308 * 0.0825 = 25.41
Now you add the tax to the total value.
308 + 25.41 = 333.41
The total value including tax is $333.41. The online retailer is offering a 30% savings (discount), so multiply the total price including tax by 30% (0.30).
333.41 * 0.30 = 100.023
Now you subtract the discount from the total price.
333.41 - 100.023 = 233.38700
The question say the answer rounded to the nearest cent or hundredths, so your final answer is 233.39.
The final price of the clothing including all discounts and taxes is $233.39.

A chef orders carrots and celery in bulk. The chef orders 2.2 lb more carrots than celery. The two orders weigh 10.8 lb
combined.
What is the weight of the carrots?
Answer:
Y= 7.9 lb
X= 10.1 lb
Step-by-step explanation:
The chef orders 2.2 lb more carrots than celery. The two orders weigh 10.8 lb combined.
Let carrot= x
Let celery= y
X+y = 18...... equation one
X= 2.2 +y.... equation two
Substituting the value of x into equation one
2.2 +y +y =18
2y= 18-2.2
2y= 15.8
Y= 7.9 lb
Substituting the value of yinto equation 2
X= 2.2 +y
X= 2.2 + 7.9
X= 10.1 lb
What is the remainder when f(x) = x^2 + 14x − 8 is divided by (x − 5)? 103 88 87 72
Answer:
The remainder is 87.
Step-by-step explanation:
By definition of remainder theorem, whenever a polynomial f(x) is divided by (x-b) the remainder will be: f(b)
Following the Remainder Theorem, in this question the remainder will be f(5).
In this case we were given f(x) as
f(x) = x^2 + 14x − 8
We're are to find the remainder when it is divided by (x-5)
Then(x-5)= 0
X=5
If we substitute x=5 into equation of f(x), we will have the remainder of
f(x) = x^2 + 14x − 8
f(4)= (5)^2 +14(5)-8
f(4)=25+70-8
f(4)=87
Hence, The remainder is 87.

In the healthy handwashing survey conducted by Bradley Corporation, a study was found that 64% of adult Americans operate the flusher of toilets in public restrooms with their foot. Suppose a random sample of n=20 adult Americans is obtained, and the number x who flush public toilets with their feet is recorded.
A) Explain why this is a binomial experiment.
B) Find and interpret the probability that exactly 12 flush public toilets with their foot.
C) Find and interpret the probability that at least 16 flush public toilets with their foot.
D) Would it be unusual to find more than 17 who flush public toilets with their foot? Why?
Answer:
A) It fulfills the condition of binomial experiment
B) P (x=12) =0.1678
C)P ( x ≥16)= 0.1011
d) P (x>17) =0.0096 < 0.5
Step-by-step explanation:
A. The binomial probability distribution has the following four properties
1. the outcomes of each trial maybe classified into success and failure.
2) the probability of success p remains constant for all trials.
3) the successive trials are all independent.
4) the experiment is repeated a fixed number of times ,n.
These all conditions are fulfilled by the given question so it is a binomial experiment.
B) P (x=12) = 20C12 (0.64)^12 * (1-0.64)^8= 0.1678
C) P ( x ≥16) = P (x=16) + P (x=17) + P (x=18) + P (x=19)+ P (x=20)
where
P (x=16)= 20C16 (0.64)^16 * (1-0.64)^4= 0.0645
P (x=17)= 20C17 (0.64)^17 * (1-0.64)^3= 0.0270
P (x=18)= 20C18 (0.64)^18 * (1-0.64)^2= 0.0080
P (x=19)=20C19 (0.64)^10 * (1-0.64)^1= 0.0015
P (x=20)= 20C20 (0.64)^20 * (1-0.64)^0= 0.0001
so
P ( x ≥16)= 0.0645+ 0.0270 +0.0080+ 0.0015+0.0001= 0.1011
d) P (x>17)= P (x=17) + P (x=18) + P (x=19)+ P (x=20)
=0.0270 +0.0080+ 0.0015+0.0001
=0.0096
From this we see that the probability of more than 17 people who flush public toilets with their foot is unusual because it is far away from the mean which is supposed to be somewhere 0.5 in a given distribution.

an inverted conical water tank with a height of 20 ft and a radius of 8 ft is drained through a hole in the vertex (bottom) at a rate of 4 ft^3/sec. Find the rate of change of the water depth when the water depth is 10 ft.
Answer:
the rate of change of the water depth when the water depth is 10 ft is; [tex]\mathbf{\dfrac{dh}{dt} = \dfrac{-25}{100 \pi} \ \ ft/s}[/tex]
Step-by-step explanation:
Given that:
the inverted conical water tank with a height of 20 ft and a radius of 8 ft is drained through a hole in the vertex (bottom) at a rate of 4 ft^3/sec.
We are meant to find the rate of change of the water depth when the water depth is 10 ft.
The diagrammatic expression below clearly interprets the question.
From the image below, assuming h = the depth of the tank at a time t and r = radius of the cone shaped at a time t
Then the similar triangles ΔOCD and ΔOAB is as follows:
[tex]\dfrac{h}{r}= \dfrac{20}{8}[/tex] ( similar triangle property)
[tex]\dfrac{h}{r}= \dfrac{5}{2}[/tex]
[tex]\dfrac{h}{r}= 2.5[/tex]
h = 2.5r
[tex]r = \dfrac{h}{2.5}[/tex]
The volume of the water in the tank is represented by the equation:
[tex]V = \dfrac{1}{3} \pi r^2 h[/tex]
[tex]V = \dfrac{1}{3} \pi (\dfrac{h^2}{6.25}) h[/tex]
[tex]V = \dfrac{1}{18.75} \pi \ h^3[/tex]
The rate of change of the water depth is :
[tex]\dfrac{dv}{dt}= \dfrac{\pi r^2}{6.25}\ \dfrac{dh}{dt}[/tex]
Since the water is drained through a hole in the vertex (bottom) at a rate of 4 ft^3/sec
Then,
[tex]\dfrac{dv}{dt}= - 4 \ ft^3/sec[/tex]
Therefore,
[tex]-4 = \dfrac{\pi r^2}{6.25}\ \dfrac{dh}{dt}[/tex]
the rate of change of the water at depth h = 10 ft is:
[tex]-4 = \dfrac{ 100 \ \pi }{6.25}\ \dfrac{dh}{dt}[/tex]
[tex]100 \pi \dfrac{dh}{dt} = -4 \times 6.25[/tex]
[tex]100 \pi \dfrac{dh}{dt} = -25[/tex]
[tex]\dfrac{dh}{dt} = \dfrac{-25}{100 \pi}[/tex]
Thus, the rate of change of the water depth when the water depth is 10 ft is; [tex]\mathtt{\dfrac{dh}{dt} = \dfrac{-25}{100 \pi} \ \ ft/s}[/tex]
Answer:
the rate of change of the water depth when the water depth is 10 ft is;

Pleaase help with both questions ! PLease explain if you can!
Answer:
See below for answers to both questions.
Step-by-step explanation:
Question 13)
We know that the perimeter is the sum of all of the side lengths of the square, and we know that a square has 4 sides that are all the same length. This lets us set up the following equation:
4(10x + 6) = 74
To solve this equation, we should first distribute the 4 through the parentheses using the distributive property.
40x + 24 = 74
Next, we should subtract 24 from both sides of the equation.
40x = 50
Finally, we should divide both sides by 40.
x = 50/40 = 1.25
Therefore, the answer to question 13 is x = 1.25.
Question 14)
If we know the rectangle and triangle have the same perimeter, we can set up the following equation:
2(4x-1) + 2(x-1) = (4x + 1) + (3x + 5) + (x + 1)
We should begin by simplifying the left side of the equation using the distributive property, as we did above.
8x - 2 + 2x -2 = 4x + 1 + 3x + 5 + x + 1
Next, we can combine like terms on both sides of the equation. This means adding together the constant terms (numbers) and also combining the variable terms (x's). This is modeled below:
(8x + 2x) + (-2 + -2) = (4x + 3x + x) + (1 + 5 + 1)
10x - 4 = 8x + 7
Next, we should subtract 8x from both sides.
10x - 8x - 4 = 8x - 8x + 7
2x - 4 = 7
Next, we should add 4 to both sides.
2x - 4 + 4 = 7 +4
2x = 11
Finally, we should divide both sides by 2.
x = 11/2 = 5.5
The question asks us to find the perimeter, so we can use the perimeter of the rectangle:
10x - 4 = 10(5.5) - 4 = 51
Therefore, the answer is 51 units.
Hope this helps!

What is the decision regarding the differences between the observed and expected frequencies if the critical value of the chi-square is 9.488 and the computed chi-square value is 6.079 g
Answer:
Accept the null hypothesis if it is two tailed test.
Step-by-step explanation:
The null hypotheses can only be accepted if it is a two tailed test and calculated chi square must be less than the critical value of chi square.
Then the difference between the the observed and expected frequencies will be zero.
where
H0 : σ²-σ²= 0 Ha: σ²-σ²≠0
For this the critical region would be greater than the calculated value of chi square. If so we will accept the null hypothesis and reject the alternative hypothesis.

Answer Choice 1
Take it step by step!
First find what sqrt(x-7) is like. Compare it to sqrt(x).
You can see that in sqrt(x), when x = 0, y = 0. However, in sqrt(x-7), when x = 7, y = 0. When y = 0, sqrt(x-7) is 7 more, which means it is shifted 7 units to the right.
Similarly, +8 means that whatever sqrt(x-7) is, you add 8 more to y. Adding on extra for y is just moving it up by 8 units.

Debbie needs to fill juice cups for her little brother's birthday party. There are 20 juice cups and each juice cup holds 10 fluid ounces. The juice comes in 1-gallon bottles. How many 1-gallon bottles of juice will Debbie need to purchase?
Answer:
Debbie would need to purchase 2 1-gallon bottles of juice.
Step-by-step explanation:
So we have 20 cups and each cup holds 10 fluid ounces. 20 times 10 equals 200 fluid ounces. We need to see how many fluid ounces are in 1 gallon. There are 128 fluid ounces in 1 gallon. 200 divided by 128 equals to 1.56 gallons. Debbie needs more than 1 gallon. Since we have a decimal and 1 is on the left of the decimal, Debbie would need to purchase 2 1-gallon bottles of juice.

d. d
2) For a double-sampling plan for attributes, what do the following symbols represent?
a. n1
b. n2
c. c1
d. c2
e. d1
f. d2
Answer:
Step-by-step explanation:
In a single - sampling plan, when a decision on acceptance / rejection of the lot is made on the basis of only one sample, Then , the acceptance plan is said to be a single sampling plan. The single sampling plan is known as the most common and easiest sampling plan
The following symbol representation can be written as follows:
a. N → Lot size from which the sample is drawn
b. n → sample size
c. c → acceptance number
d. d → number of defectives in the sample
For example:
if we take a randomized sample of size 'n' from the Lot size.
The next step will be to inspect all items in the sample to find the defectives 'd'
The decision rule is that:
If the number of defectives is less than or equal to acceptance number, then answer is YES i.e d ≤ c, Then , we accept the Lot
If the number of defectives is not less than or equal to acceptance number, then the answer is NO . Then , we reject the Lot.
So if we reject, we either do 100% inspection or return the lot to the supplier.
In a double sampling plan , the decision on acceptance/rejection of the Lot is based on two samples.
The following symbol representation can be written as follows:
a. n1 → number of size of sample 1
b. n2 → number of size of sample 2
c. c1 → acceptance number for sample 1
d. c2 → acceptance number for sample 2
e. d1 → number of defectives in sample 1
f. d2 → number of defectives in sample 2

An automobile technician claims that the mean amount of time (in hours) per domestic car repair is more than that of foreign cars. Assume that two samples are independent. Let the domestic car repair times be the first population and the foreign car repair times be the second population.
A. H: mu1< mu2
B. H1: mu1 = mu2
C. H: mu1>mu2
D. H: mu not= mu2
Answer:
A. H: mu1< mu2
Step-by-step explanation:
Given that :
Mean amount of time per domestic cars = mu1
Mean amount of time per foreign cars = mu2
Automobile technicians claim :
The mean amount of time (in hours) per domestic car repair is more than that of foreign cars. This will be the Null hypothesis.
Null hypothesis : mu1 > mu2
The alternative hypothesis will negate the Null hypothesis and will hence be the opposite. This can this be expressed as :
Alternative hypothesis : mu1 < mu2
The temperature at the point (x, y, z) in a substance with conductivity K = 4.5 is u(x, y, z) = 5y2 + 5z2. Find the rate of heat flow inward across the cylindrical surface y2 + z2 = 7, 0 ≤ x ≤ 2.
Answer:
The rate of the heat flow = 1260 π
Step-by-step explanation:
From the information given :
k = 4.5
u(x,y,z) = 5y² + 5z²
Surface cylinder:
y² +z² = 5, 0 ≤ x ≤ 2
[tex]\mathtt{\overline F = \bigtriangledown u = -k(0,10y, 10z )}[/tex]
[tex]\mathtt{\overline F = -4.5(0,10y, 10z )}[/tex]
[tex]\mathtt{\overline F = (0,-45y, -45z ) \ --- (1)}[/tex]
Now parameterizing the surface by :
x = u , y = [tex]\mathtt{\sqrt{7} \ cos \ t}[/tex] , z = [tex]\mathtt{\sqrt{7} \ sin \ t}[/tex]
0 ≤ x ≤ 2 , 0 ≤ t ≤ 2π
[tex]\mathtt{{ \left. \begin{array}{1} \overline{r_y} = (1,0,0) } \\ \\ \overline{r_t} = (0, \ - \sqrt{7}\ sin \ t, \sqrt{7} \ cos \ t) \end{array} \right\} = r_u \times r_t}[/tex]
[tex]\mathtt{\overline r_u \times \overline r_t = ( -0, - \sqrt{7} \ cos \ t , - \sqrt{7} \ sin \ t) --- (2)}[/tex]
Taking integral of both equations; we have:
[tex]\mathtt{= \int ^{2}_0 \int ^{2 \pi}_{0} (0, -45y, -45 z) (0, - \sqrt{7} \ cos \ t, - \sqrt{7} \ sin \ t) \ dtdu}[/tex]
[tex]\mathtt{= \int ^{2}_0 \int ^{2 \pi}_{0} ( 45\sqrt{7} \ y\ cos \ t+ 45 \sqrt{7} \ z \ sin \ t) \ dtdu}[/tex]

which property is represented by 5+8(-8)=-8+5?
indentity, associative, commutative, distributive
Answer:
The Commutative property is represented by 5 + (-8) = -8 + 5.
Step-by-step explanation:
We are the following the following expression below;
5 + (-8) = -8 + 5
Identity property;This property says that is any number is added to 0, then the result is the number itself, i.e.;
2 + 0 = 2 or (-7) + 0 = -7.
Associative property;Suppose there are three numbers; a, b and c.
So, this property hold the condition that; a + (b + c) = (a + b) + c
If we add the second and third numbers and then add the first number to it or if we add the first and second numbers and then add the third number to it, the result will be the same.
Commutative property;Suppose there are two numbers 6 and 8.
This property states that if we add 6 + 8 or 8 + 6, both are equal, i,e;
6 + 8 = 8 + 6
14 = 14.
Distributive property;This property states the following condition;
a [tex]\times[/tex] (b + c) = (a [tex]\times[/tex] b) + (a [tex]\times[/tex] c)
So, 5 + (-8) = -8 + 5 is represented by the commutative property.
