Answer:
$48.76
Step-by-step explanation:
So, Sara bought the pair of shoes for $46 due to a discount.
Sales tax was 6% or 0.06. In other words, she had to pay 0.06(46)=2.76 for tax.
Thus, the total amount Sara paid for the shoes is $46+$2.76=$48.76

The breaking strength of hockey stick shafts made of two different graphite-Kevlar composites yield the following results (in newtons):
Composite A: 487.3 444.5 467.7 456.3 449.7 459.2 478.9 461.5 477.2
Composite B: 488.5 501.2 475.3 467.2 462.5 499.7 470.0 469.5 481.5
485.2 509.3 479.3 478.3 491.5
Assuming normality, can you conclude that the mean breaking strength is smaller for hockey sticks made from composite B by at least 2 newtons? Carry out the appropriate test by hand.
Answer:
We reject H₀
we don´t have evidence to claim the strength of composite B is smaller than the strength of composite B by at least 2 [N]
Step-by-step explanation:
From data, we calculate μ₁, s₁ and, μ₂, s₂ mean and standard deviation of samples A and B respectively
μ₁ = 464,7 s₁ = 13,42 Composite A
μ₂ = 479,49 s₂ = 13,38 Composite B
n₁ ; n₂ < 30 then we should use t -student table
Test Hypothesis:
Null Hypothesis H₀ μ₂ - μ₁ >= 2
Alternative Hypothesis Hₐ μ₂ - μ₁ < 2
Assuming CI 95 % α = 5 % α = 0,05 and degree of freedom is
df = n₁ + n₂ - 2 df = 9 + 9 - 2 df = 16
Then for a one tail test t(c) = 1,746 and to compte t(s)
t(s) = ( μ₂ - μ₁ - 2 ) / sp * √ 1/n₁ + 1/n₂
sp² = ( n₁ - 1 )*s₁² + ( n₂ - 1 )*s₂² / n₁ + n₂ - 2
sp² = 8 * (13,42)² + 8 * (13,38)² / 16
sp² = (8 * 180,1 + 8 * 179) / 16
sp² = 179,55
sp = 13,40
then
t(s) = ( 479,49 - 464,7 - 2 ) / 13,40*√1/9 +1/9
t(s) = 12,79 / 13,40*0,4714
t(s) = 12,79/6,32
t(s) = 2,02
t(s) > t(c)
2,02 > 1,746
t(s) is in the rejection region, therefore we reject H₀ we don´t have evidence to claim the strength of composite B s smaller than the strength of composite B by at least 2 [N]

A piece of rope falls out of a hot air
balloon from a height of 5,184 ft. If the
equation for height as a function of time
is h(t) = -16t2 - initial height where t is
time in seconds and h(t) is height in feet,
how many seconds will it take for the
piece of rope to hit the ground?
Answer:
18 seconds
Step-by-step explanation:
Given the equation for height as a function of time expressed as
h(t) = -16t² - initial height, if initial height is 5,184ft, the expression will become;
h(t) = -16t² - 5,184
t is time in seconds
h(t) is height in feet
The height of the rope on the ground is zero. In order to calculate the amount of seconds it will take the piece of rope to hit the ground, we will substitute h(t) = 0 into the modeled equation as shown:
Since the body falls downwards (negative direction), initial height = -5184 ft
h(t) = -16t² - -(5,184)
0 = -16t² + 5,184
0+16t² = 5184
16t² = 5184
16t²/16 = 5184/16
t² = 324
t = √324
t = 18 seconds
Hence, it will take the rope 18seconds to hit the ground.
Answer:18 seconds

Pls help!! Find the area of the lighter shaded region and round to the nearest tenth.
Answer:
5.1 cm² approximately
Step-by-step explanation:
A lighter= Area inscribed -1/2r² sin80°
A lighter=π r² (80°/360°) -1/2(5 cm)² sin 80°
A lighter=π(5cm)² (80°/360°) -1/2(5 cm)² sin 80°
A lighter=3.14*25cm²(80°/360°) - 12.5cm² sin 80°
A lighter=17.444…cm² - 12.31009... cm²
A lighter=5.13cm² approximately
Answer: =approx 5.13 cm²
Step-by-step explanation:
Lets find the area of the region that is blue ( dark blue+light blue)
S= pi*r^2/360*80=pi*25*2/9=pi*50/9
The lighter region' s area is the S- S(triangle marked with dark blue)
The area of this triangle is r^2*sin(80°)/2= 25*sin(80°)/2=
=12.5*sin(80°)
So the required area Sreg= pi*50/9-12.5*sin(80°)=
= approx 3.14*50/9-12.5*0.985=approx 5.13 cm²

Answer: 5/33
Step-by-step explanation: There are 12 fruits and 5 are oranges.
If you draw an orange, then there are 11 fruits and 4 oranges. (5/12)x(4/11)=20/132 or 5/33 in simplest form.
Tom can type 120 words in 3 minutes. What is the ratio of words typed to minutes? Question 2 options: A. 1 : 117 B. 1 : 40 C. 40 : 1 D. 117 : 1
Answer:
C
Step-by-step explanation:
Since he writes 120 words in 3 minutes, we know that Tom will write 120 / 3 = 40 words in 1 minute, therefore the ratio is 40 : 1. It's not 1 : 40 because the question is asking for the ratio of words typed to minutes, not minutes to words typed.
BRAINLIEST IF RIGHT!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Trevon's Custom Kitchen Supplies sells handmade forks and spoons. It costs the store $1.80 to buy the supplies to make a fork and $1.40 to buy the supplies to make a spoon. The store sells forks for $4.60 and spoons for $5.40. Last April Trevon's Custom Kitchen Supplies spent $24.60 on materials for forks and spoons. They sold the finished products for a total of $73.80. How many forks and how many spoons did they make last April? A. 8 forks and 10 spoons B. 8 forks and 8 spoons C. 9 forks and 9 spoons D. 9 forks and 6 spoons
Answer:
D. 9 forks and 6 spoons
Step-by-step explanation:
Let's calculate how many forks and spoons were made. We need to guess a pair of variable values that will add up to $24.60. We'll do this by substituting all the possible pairs in:
Here's the pair for A:
[($1.80 * a) + ($1.40 * b)]
= [($1.80 * 8) + ($1.40 * 10)]
= [$14.40 + $14]
= $28.40
Is $28.40 equal to $24.60? No, this is not correct.
Here's the pair for B:
[($1.80 * a) + ($1.40 * b)]
= [($1.80 * 8) + ($1.40 * 8)]
= [$14.40 + $10.80]
= $25.20
Is $25.20 equal to $24.60? No, this is not correct.
Here's the pair for C:
[($1.80 * a) + ($1.40 * b)]
= [($1.80 * 9) + ($1.40 * 9)]
= [$16.20 + $12.60]
= $28.80
Is $28.80 equal to $24.60? No, this is not correct.
Here's the pair for D:
[($1.80 * a) + ($1.40 * b)]
= [($1.80 * 9) + ($1.40 * 6)]
= [$16.20 + $8.40]
= $24.60
Is $24.60 equal to $24.60? Yes, this is correct.
Therefore, we know the answer is (D) 9 forks and 6 spoons
We can also check by substituting these values to find the amount Trevon's Custom Kitchen Supplies earned last April:
[($4.60 * a) + ($5.40 * b)]
= [($4.60 * 9) + ($5.40 * 6)]
= [$41.40 + $32.40]
= $73.80
This is equal to the amount of money earned last April.
I hope this helps! Tell me if I'm wrong, please!

"If the average cholesterol level is 194 with a standard deviation of 15, what percentage of children have a cholesterol level lower than 199? Answers are rounded to the nearest whole percent."
Answer:
63%
Step-by-step explanation:
Given the following :
Average cholesterol level or mean (m) = 194
Standard deviation (sd) = 15
what percentage of children have a cholesterol level lower than 199?
P(X < 199)
Assume a normal distribution :
Find the z-score :
Z = (score - mean) / standard deviation
Score = 199
Z = (199 - 194) / 15
Z = 5 / 15
Z - score = 0.3333
P(Z < 0.33) :
Using the z - table ; 0.33 = 0.6293
P(Z < 0.33) = 0.6293
0.6293 * 100% = 62.93%

A graphing calculator is recommended. A function is given. g(x) = x4 − 5x3 − 14x2 (a) Find all the local maximum and minimum values of the function and the value of x at which each occurs. State each answer rounded to two decimal places.
Answer:
The local maximum and minimum values are:
Local maximum
[tex]g(0) = 0[/tex]
Local minima
[tex]g(5.118) = -350.90[/tex]
[tex]g(-1.368) = -9.90[/tex]
Step-by-step explanation:
Let be [tex]g(x) = x^{4}-5\cdot x^{3}-14\cdot x^{2}[/tex]. The determination of maxima and minima is done by using the First and Second Derivatives of the Function (First and Second Derivative Tests). First, the function can be rewritten algebraically as follows:
[tex]g(x) = x^{2}\cdot (x^{2}-5\cdot x -14)[/tex]
Then, first and second derivatives of the function are, respectively:
First derivative
[tex]g'(x) = 2\cdot x \cdot (x^{2}-5\cdot x -14) + x^{2}\cdot (2\cdot x -5)[/tex]
[tex]g'(x) = 2\cdot x^{3}-10\cdot x^{2}-28\cdot x +2\cdot x^{3}-5\cdot x^{2}[/tex]
[tex]g'(x) = 4\cdot x^{3}-15\cdot x^{2}-28\cdot x[/tex]
[tex]g'(x) = x\cdot (4\cdot x^{2}-15\cdot x -28)[/tex]
Second derivative
[tex]g''(x) = 12\cdot x^{2}-30\cdot x -28[/tex]
Now, let equalize the first derivative to solve and solve the resulting equation:
[tex]x\cdot (4\cdot x^{2}-15\cdot x -28) = 0[/tex]
The second-order polynomial is now transform into a product of binomials with the help of factorization methods or by General Quadratic Formula. That is:
[tex]x\cdot (x-5.118)\cdot (x+1.368) = 0[/tex]
The critical points are 0, 5.118 and -1.368.
Each critical point is evaluated at the second derivative expression:
x = 0
[tex]g''(0) = 12\cdot (0)^{2}-30\cdot (0) -28[/tex]
[tex]g''(0) = -28[/tex]
This value leads to a local maximum.
x = 5.118
[tex]g''(5.118) = 12\cdot (5.118)^{2}-30\cdot (5.118) -28[/tex]
[tex]g''(5.118) = 132.787[/tex]
This value leads to a local minimum.
x = -1.368
[tex]g''(-1.368) = 12\cdot (-1.368)^{2}-30\cdot (-1.368) -28[/tex]
[tex]g''(-1.368) = 35.497[/tex]
This value leads to a local minimum.
Therefore, the local maximum and minimum values are:
Local maximum
[tex]g(0) = (0)^{4}-5\cdot (0)^{3}-14\cdot (0)^{2}[/tex]
[tex]g(0) = 0[/tex]
Local minima
[tex]g(5.118) = (5.118)^{4}-5\cdot (5.118)^{3}-14\cdot (5.118)^{2}[/tex]
[tex]g(5.118) = -350.90[/tex]
[tex]g(-1.368) = (-1.368)^{4}-5\cdot (-1.368)^{3}-14\cdot (-1.368)^{2}[/tex]
[tex]g(-1.368) = -9.90[/tex]

Coordinates of the midpoint are: (1, 7.5)
Step-by-step explanation:
Find the distance between the x-values of the given points,and the distance between the y-values of them:
distance between 7 and 8 (y-values of N and A respectively) is: 8-7 = 1
then half of that is 0.5, therefore, the midpoint should have for y value the value of the minimum between 7 and 8 (7) plus 0.5, that is, the y-value of the midpoint is: 7.5
Now for the x-value of the midpoint we do something similar:
The distance between 6 and -4 (x-values of B and A respectively) is: 10 units, half of this is 5, and therefore, the x-value of the midpoint should be at the minimum of those two values (-4) plus 5 units, that is: -4 + 5 = 1
Coordinates of the midpoint are: (1, 7.5)
Devon bought running shocs at a price that was 1/4 off the original price of $88. He paid a sales tax of 7% on
the discounted price and gave the clerk four $20 bills.
How much change should he receive?
A. $ 4.62
B. $ 7.84
C. $ 9.38
D. $12.46
E. $18.62
The correct answer is C. $ 9.38
Explanation:
The first step to solve this mathematical problem is to know the price of the shoes. About this, we know the price is 1/4 of $88 plus taxes. You can find how much is 1/4 of $88 by following this process:
1. Write the amounts given
[tex]\frac{1}{4}[/tex] of [tex]88[/tex]
2. Divide the number by the denominator (bottom number) and then multiply by the numerator
[tex]88[/tex] ÷ [tex]4 = 22[/tex]
[tex]22 x 1 = 22[/tex]
This means the discount was $22 and $88- $22 = $66, which is the price with the discount. Now, it is necessary to add the sales tax, which can be done by finding the 7% of $66 and adding this number to $66 (the price of the shoes including the 1/4 discount)
1. Write the values
66 = 100 (66 represents the total or 100%)
x = 7 (7% is the value you want to know and the x represents the value is not known)
2. Cross multiply
x 100 = 462
3. Find x
x = 462 ÷ 100
x = 4. 62 ( value of taxes)
Now, add the taxes to the price $66 + $ 4.62 = $70.62 (price with taxes). Finally, we know Devon paid using four $20 bills. This means he gave the clerk $80 ($20 x 4 = $80). Finally, to know how much is the change subtract the price of the shoes from the money Devon gave the clerk $80 - $70.62 = $9.38

In May 1998, forest fires in southern Mexico and Guatemala spread smoke all the way to Austin. Those fires consumed forest land at a rate of 25200 acres/week. On the average, how many square meters of forest are burned down every minute
Answer:
On average the size of the area of the forest burnt down every minute is 10117.14 m²
Step-by-step explanation:
The given parameters are;
The rate consumption of forest land by the fire = 25200 acres/week
Therefore, we have;
The number of minutes in one week = 60 × 24 × 7 = 10080 minutes
Therefore;
The rate consumption of forest land by the fire per minute = 25200/10080 acres/minute = 2.5 acres/minute
The number of square meters in one acre is given as follows;
1 acre = 4,046.856 m²
Therefore;
2.5 acres/minute = (2.5 × 4,046.856 m²/(1 acre)) acres/minute = 10117.14 m²/minute
Which give;
The rate consumption of forest land by the fire= 10117.14 m²/minute.
The rate of the fire consumption of the forest is 10117.14 m²/minute.

Qualitative variables are categorized or labelled to belong to a certain category or group.
There are two types of qualitative variables, Categorical and ordinal.
Categorical variable are those variables that are labelled in non-numeric or numeric form, where the numbers have no value. The order also does not matters. For example, the number on the jerseys of football players. It is not necessary that the player number 1 is actually the best player.
Ordinal variables are those variables where the label or category has to be in order. For example, the rank of students in the statistics class.
Quantitative variables are in numerical form and can be measured.
There are two types of quantitative variables, discrete and continuous.
Discrete variables are those variables that assume finite and specific value. For example, the number of girls in each section of a school.
Continuous variables are those variables that can assume any number of values between a specific interval. For example, the time it takes to reach point B from A.

In the problem below, what is the SECOND operation that should be performed:
42 - (28 + 7) + 111
Answer:
Add -28 and -7 (2nd operation)
Step-by-step explanation:
42-(28+7)+111
Step 1: Remove the brackets
42-28-7-11
Step 2: Add 42 and 111( 1st operation ) you can also rewrite to avoid confusion
42+111-28-7
= 153-28-7
Step 3: Add -28 and -7 (2nd operation)
153-28-7
=153-35
Step 4 : Subtract

Answer:
$42
Step-by-step explanation:
Original price: $56
Discount: 25%
A discount of 25% means that the discount is 25% of the price of the item, so you need to subtract 25% of the price of the item from the original price of the item.
Let's find an expression for the amount of the discount.
25% of $56 = 25% * $56 = 0.25 * $56
The amount of discount is 0.25 * $56.
Now we subtract that amount form the original price of $56.
$56 - 0.25 * $56 = $56 - $14 = $42

Solve the system by substitution. x= x= \,\,-y-5 −y−5 -3x+7y= −3x+7y= \,\,-45 −45
Answer:
(1, -6)
Step-by-step explanation:
the layout of your question is kind of confusing, but i'm guessing this is the system of equations
x = -y - 5
-3x + 7y = -45
plug in x to the second equation
-3(-y - 5) + 7y = -45
distribute
3y + 15 + 7y = -45
combine like terms
10y = - 60
divide by 10
y = -6
plug y into first equation
x = -(-6) - 5
x = 6 - 5
x = 1
