Required
State if the table shows x as a function of y
x being a function of y means
[tex]x = f(y)[/tex]
i.e. x represents the output while y represents the input of the function
Note that each value of y (input) must be assigned to separate values of x (output) for a function to be established
Having said;
Next step: We have to examine the x and y column
In the y column, the value 7 occurred twice (as shown below)

This implies that;
Input 7 gives output of 0 and 1.
Hence, this is not a function.

c. Sumana runs a tea shop and she buys 7.5L of milk everyday. If she
uses 4.75L of milk in the morning and the remaining milk in the
evening. Find the quantity of milk she uses in the evening
Answer:
2.75 L
Step-by-step explanation:
This is the problem of subtraction.
Total Milk sumana has = 7.5 l
Milk used in the morning = 4.75 L
Milk left for evening = Total Milk sumana has - Milk used in the morning
Milk left for evening = 7.5 l - 4.75 l = 2.75 L

For a confidence level of 85%, find the critical value for a normally distributed variable. The sample mean is normally distributed if the population standard deviation is known.
Answer:
The value is [tex]Z_{\alpha } = 1.439[/tex]
Step-by-step explanation:
From the question we are told that
The confidence level is C = 85%
Generally the level of significance is mathematically represented as
[tex]\alpha = (100 - 85 )\%[/tex]
[tex]\alpha = 0.15[/tex]
Now from the normal distribution table the critical value of [tex]\alpha[/tex] is
[tex]Z_{\alpha } = 1.439[/tex]

name each angle in as many different ways as possible
========================================
Explanation:
To name an angle, we list 3 points on the angle such that the middle point is the vertex of the angle. The vertex is where the two rays are joined (at the endpoints).
So we could say "angle JLG" as you wrote in the first box, or we could say "angle GLJ". This is the same because L is in the middle each time. So the order doesn't matter as long as L is in the middle.
The third way to name this angle is to say "angle 2" or [tex]\angle 2[/tex] for short.
Another way to write this angle is to name it by the vertex point alone.
----------------------
Note: In this case, saying "angle L" is enough info to be able to pinpoint the proper angle. Though in general this naming convention is very limited. If we had other rays attached to point L (say ray LH where point H is not on any of the two rays shown), then writing "angle L" is ambiguous. So keep this in mind.
What happens when the two addends have opposite signs and the number with the larger magnitude (size) is positive?
Answer:
The smaller addend is subtracted from the bigger addend
Step-by-step explanation:
Represent the two numbers with a and b such that a > b
So, the mathematical representation will be
[tex]+a + (-b)[/tex]
Open the bracket
[tex]+a -b[/tex]
This implies that the smaller addend (b) is subtracted from the bigger addend (b)
Take for instance; a = 6 and b = 4
This gives
[tex]+6 + (-4)[/tex]
Open the bracket
[tex]= +6 - 4[/tex]
[tex]= 2[/tex]

Answer:
[tex]P(a\ or\ b) = 0.65[/tex]
Step-by-step explanation:
Given
P(a) = 0.60
P(b) = 0.20
P(a and b) = 0.15
Required
Determine P(a or b)
In probability;
[tex]P(a\ and\ b) = P(a) + P(b) - P(a\ or\ b)[/tex]
Substitute values for P(a and b), P(a) and P(b)
[tex]0.15 = 0.60 + 0.20 - P(a\ or\ b)[/tex]
Collect Like Terms
[tex]P(a\ or\ b) = 0.60 + 0.20 - 0.15[/tex]
[tex]P(a\ or\ b) = 0.65[/tex]
Hence, option B answers the question

If 4x— 3 = 2x + 9, then x = ?
x=6
x=2
x=1
x=3
Answer:
x=6 is the answer
Step-by-step explanation:
4x-3=2x+9
adding 3 on both sides
4x-3+3=2x+9+3
4x=2x+12
subtracting 2x on both sides
4x-2x=2x-2x+12
2x=12
dividing 2 on both sides
2x/2=12/2
x=6 is the answer.
hope it will help you :)
Step-by-step explanation:
4x - 3 = 2x + 9
Bringing like terms on one side
4x - 2x = 9 + 3
2x = 12
x = 12/ 2
x = 6
Suppose coffee is initially brewed at 205 F and the room temperature is 70 F. Determine the value of kk if the temperature of the coffee drops from 205 F to 200 F in the first two minutes after brewing. Round answer to 4 decimal places.
Answer:
0.0189
Step-by-step explanation:
We solve for this using Newton's Law of cooling.
The formula for Newton's Law of cooling =
T −Ts = (To−Ts)e^-kt
T = Temperature after cooling
To = Initial temperature
Ts = Room temperature
k = constant
t = time = 2 mins
(200 - 70) = (205 - 70)e^-2k
130 = 135e^-2t
e^-2k= 130/135
k = In(130/135)/-2
k = 0.018870164
Approximately to 4 decimal places = 0.0189
Therefore, the value of k = 0.0189
Suppose a horticulturist measures the aboveground height growth rate of four different ornamental shrub species grown in a greenhouse. The shrubs were grown from a random sample of seeds, and they were all grown in the same soil mixture and in the same size pot. To ensure that any slight differences in the environmental conditions throughout the greenhouse are not confounded with species, she randomizes the location of the pots throughout the greenhouse. The table contains a summary of her data. Population Sample Sample Sample Population description size standard deviation 17.153 cm/year 2.666 cm/year x2 = 13.983 cm/year s2-3.605 cm/year 15.120 cm/year3 3.774 cm/year x4-14.328 cm/year s.-3.011cm/year mean 1 Species 1 n1-20 Species 2 n2=20 3 Species 3 n 20 Species 4 n4-20 The growth rate distributions of each sample are approximately normal, and the data do not contain outliers.

Complete Question
The complete question is shown on the first uploaded image
Answer:
The decision is to reject the null hypothesis at a significant level of significance [tex]\alpha = 0.05[/tex] There is sufficient evidence to conclude that at least one of the population mean is different from at least of the population
Step-by-step explanation:
From the question we are told that the claim is
The mean growth rates of all four species are equal.
The null hypothesis is
[tex]H_o : \mu _1 = \mu_2 = \mu_3 = \mu_4[/tex]
Th alternative hypothesis is
[tex]H_a: at \ least \ one \ of \ the \ means \ is \not\ equal[/tex]
From question the p-value is [tex]p-value = 0.015[/tex]
And since the [tex]p-value < \alpha[/tex] so the null hypothesis will be rejected
So
The decision is to reject the null hypothesis at a significant level of significance [tex]\alpha = 0.05[/tex] There is sufficient evidence to conclude that at least one of the population mean is different from at least of the population

Step-by-step explanation:
Simplify the expression:
[tex] \sf \implies(10 {x}^{2} - 1 + 4x) + (3 + 5 {x}^{2} - 4x)[/tex]
Grouping like terms, 10x² + 5x² + 4 x - 4 x - 1 + 3 = (10 x² + 5x²) + (4 x - 4 x) + (-1 + 3):
[tex] \sf \implies (10 x^2 + 5 x^2) + (4 x - 4 x) + (-1 + 3)[/tex]
10x² + 5x² = 15x²:
[tex] \sf \implies 15 x^2 + (4 x - 4 x) + (-1 + 3)[/tex]
3 - 1 = 2:
[tex] \sf \implies 15 x^2 + (4 x - 4 x) + 2[/tex]
4 x - 4 x = 0:
[tex] \sf \implies 15 x^2 + 2[/tex]

Step-by-step explanation:
which of the following represents the factorization of the trinomial below x^2-17x+30
Hello, if [tex]x_1[/tex] and [tex]x_2[/tex] are two zeroes, we can write
[tex]x^2-17x+30=(x-x_1)(x-x_2)=x^2-(x_1+x_2)x+x_1\cdot x_2[/tex]
It means that the coefficients in x must be equal, meaning
[tex]x_1+x_2=17=2+15[/tex]
and the constant terms must be equal, meaning
[tex]x_1\cdot x_2=30 = 2 * 15[/tex]
So the zeroes are 2 and 15.
[tex]x^2-17x+30=x^2-15x-2x+30\\\\=x(x-15)-2(x-15)\\\\\boxed{=(x-2)(x-15)}[/tex]

CORRECT ANSWER GETS BRAINLIEST!!
Answer:
Step-by-step explanation:
To have Distance proportional to time, the person or object must keep a steady or constant rate like speed.
Let's first look at A runner sprinting in the 100 meter dash, since it tells you nothing about time it goes to not enough information.
Now look at An airplane starting at the end of the runway and taking off, it tells you nothing about time so, not enough information.
Now on to A marathon runner jogging at a constant speed for 45 minutes, this is distance proportional to time, because the runner has a constant rate.
The graph is distance proportional to time because, a straight slanted line indicates a constant speed. If it were curved it would not be constant.
The table with the number is distance not proportional to time because if you find the slopes of (25-5)/(10-5) and (50-25)/(15-10), they are 4 and 5 respectively which means there will not be a straight line on the graph.
Lastly, an airplane traveling at a constant speed across the country is distance directly proportional to time because it has a constant rate which is speed.
In a state's Pick 3 lottery game, you pay $1.15 to select a sequence of three digits (from 0 to 9), such as 966. If you select the same sequence of three digits that are drawn, you win and collect $258.35. Complete parts (a) through (e).
a. How many different selections are possible?
b. What is the probability of winning? (Type an integer or adecimal.)
c. If you win, what is your net profit? (Type an integer or a decimal.)
d. Find the expected value. $ (Round to the nearest hundredth as needed.)
e. If you bet $ 1.15 in a certain state's Pick 4 game, the expected value is negative −$0.89. Which bet is better, a $1.15 bet in the Pick 3 game or a $ 1.15$ bet in the Pick 4 game?
Explain.
A. Neither bet is better because both games have the same expected value.
B. The Pick 4 game is a better bet because it has a larger expected value.
C. The Pick 3 game is a better bet because it has a larger expected value.
Answer:
A) 1000 different selections
B) probability of winning = 0.001
C) Net profit on winning = $257.20
D) E(y) = -0. 89165
E) Option B - The Pick 4 game is a better bet because it has a larger expected value.
Step-by-step explanation:
A) For the different selections possible, since each of the digits from 0 - 9 can take a total of 10 digits, then the different selections possible will be = 10³ = 1000 different selections
B) To find the probability of winning, since only one pick can be a winning one. Thus probability of winning = 1/1000 = 0.001
C) Net profit on winning = Amount won - Amount staked
Amount won = $258.35
Amount staked = $1.15
Thus;
Net profit on winning = $258.35 - $1.15
Net profit on winning = $257.20
D) If we call the net profit "y", then Expected value is:
E(y) = 257.2(0.001) - 1.15(1 - 0.001)
E(y) = 0.2572 - 1.14885
E(y) = -0. 89165
E) We are told that:If you bet $ 1.15 in a certain state's Pick 4 game, the expected value is negative −$0.89
The expected value of -0.89 in pick 4 is better than that in pick 3 because it's larger.
Point T is on line segment SU. Given SU = 5x, TU = 2x, and ST = 4x – 3,
determine the numerical length of TU.
Answer:
the length of TU is 6......
The numeric length of TU for the given line segment will be 3 units.
What is a line segment?A line section that can connect two places is referred to as a segment.
In other words, a line segment is just part of a big line that is straight and going unlimited in both directions.
The line is here! It extends endlessly in both directions and has no beginning or conclusion.
Given a line segment SU in between a point T
Now,
SU = ST + TU
5x = 4x - 3 + 2x
5x = 6x - 3
6x - 5x = 3
x = 3
Now,
TU = 2x = 2(3) = 6 units.
Hence "The numeric length of TU for the given line segment will be 3 units".

If lim f (x) x →5 = 2 and lim g (x) x → 5= -6 which of these limits exist?
Answer:
E
Step-by-step explanation:
So we already know that:
[tex]\lim_{x \to 5} f(x)=2 \text{ and } \lim_{x \to 5} g(x)=-6[/tex]
So, go through each of the choices and see which ones are correct.
I)
We have:
[tex]\lim_{x \to 5} (f(x)+g(x))[/tex]
This is the same as saying:
[tex]\lim_{x \to 5} f(x)+ \lim_{x \to 5} g(x)[/tex]
And since we already know the values:
[tex]=(2)+(-6)\\=-4[/tex]
So, the limit does indeed exist.
II)
We have:
[tex]\lim_{x \to 5} \frac{f(x)}{g(x)+6}[/tex]
This is the same as:
[tex]\frac{ \lim_{x \to 5} f(x)}{ \lim_{x \to 5} g(x)+ \lim_{x \to 5} 6 }[/tex]
The bottom right one is just 6. Simplify:
[tex]\frac{ \lim_{x \to 5} f(x)}{ \lim_{x \to 5} g(x)+6}[/tex]
Substitute the values we know:
[tex]=\frac{(2)}{(-6)+6} \\=2/0[/tex]
This is a value over zero. Unlike the indeterminate form 0/0, this limit does not exist.
III)
We have:
[tex]\lim_{x \to 5} \frac{f(x)-2}{g(x)}[/tex]
Again, this is the same as:
[tex]\frac{ (\lim_{x \to 5} f(x))-2}{ \lim_{x \to 5} g(x)}[/tex]
Substitute in the values we know:
[tex]=\frac{(2)-2}{(-6)}\\ =0/-6=0[/tex]
The limit does exist and it is 0.
So, the limits of only I and III exist.
The correct answer is E.
The Futurists, a rock group, are planning a concert tour with performances to be
given in five cities: San Francisco, Los Angeles, San Diego, Denver, and Las Vegas.
how many ways can they arrange their itinerary if
a.There are no restrictions?
b.The tree performances in California must be given consecutively?
Answer:
a. 24
b. 12
Step-by-step explanation:
a. You can choose from 4 cities for the first performance, then from 3 cities, then from 2 cities, then the last city.
4 * 3 * 2 * 1 = 24
b. Think of the three performances in California as a unit. Within this unit, you can choose from 3 cities for the first one, then 2 cities for the second one, and finally 1 city for the last one.
3 * 2 * 1 = 6
Now you can have the 3 California performances first, followed by Denver, or Denver first followed by California.
6 * 2 = 12

Given the table of values below, which of the following ordered pairs are
found on the graph of the inverse function?
Answer:
see below
Step-by-step explanation:
The ordered pairs of the inverse function are the reverse of the ordered pairs of the function.
You are given the function has ordered pairs (-3, -2), (3, -1) and so on. The inverse function will have ordered pairs (-2, -3), (-1, 3), and so on. This matches choice A.
