Answer:
Pic 1: C.
Pic 2: D.
Step-by-step explanation:
1) The sample is the number of things picked out from a population. The amount of people surveyed is the sample, so it the answer choice showing "42 residents" as the sample is among a correct option. Since C is the only one with "42" as the sample, it is the answer.
2) Boosting morale isn't a negative thing, and will ultimately make residents happier. It leans towards "yes."
Adding a machine for enjoyment also leans towards "yes", because people will then have something fun to dsitract themselves with.
Many people will have access to the machine in the lunch room. They can also have a soft drink for lunch, which adds a tasty part to their lunch. It too leans towards "yes."
In a crowded lunchroom, the soft drink machine may be crowded by many people and it could take a while to get one for yourself. It is also vulnerable to breaking from too many people using it at once. It leans towards a "No" response.
Therefore, D is the best answer.

The scatter plot shows the average monthly temperature, x, and a family's monthly heating cost, y, for 23 different months.
(a) Write an approximate equation of the line of best fit for the data. It doesn't have to be the exact line of best fit.
(b) Using your equation from part (a), predict the monthly heating cost for a month with an average temperature of 35 °F.
Note that you can use the graphing tools to help you approximate the line.
1. The equation of the line of best fit is: y = -1.15x + 102.8
2. Using the equation of the line of best fit, the predicted cost is: $62.55
What is the Equation of a Line of Best Fit?The equation of a line of best fit is represented by the equation, y = mx + b, where m is the slope and b is the initial value.
1. Using two points, (72, 20) and (20, 80):
Slope (m) = change in y / change in x = (80 - 20)/(20 - 72) = 60/-52
Slope (m) = -1.15.
Substitute m = -3 and (a, b) = (72, 20) into y - b = m(x - a)
y - 20 = -1.15(x - 72)
y - 20 = -1.15x + 82.8
y = -1.15x + 82.8 + 20
y = -1.15x + 102.8
The equation of the best line of fit is y = -1.15x + 102.8.
2. Monthly heating cost, y, for a month with an average temperature of 35°F (x) will be calculated by substituting x = 35 into y = -1.15x + 102.8.
y = -1.15(35) + 102.8
y = 62.55
The predicted monthly cost is $62.55.

What is the explicit formula for this geometric sequence?
8, 4, 2, 1, …
Answer:
[tex]a_{n} = \frac{8}{2^{n-1} }[/tex]
Step-by-step explanation:
A geometric sequence has a constant ratio (r) and is defined by:
[tex]a_n=a_1r^{n-1}[/tex]
Since the first value is 8, [tex]a_{1}[/tex] = 8.
[tex]a_n=8r^{n-1}[/tex]
We can also see that a_n is double that of the next value in the sequence [tex](a_{n} = 2a_{n+1}})[/tex], hence r = 1/2
[tex]a_n=8\left(\frac{1}{2}\right)^{n-1}[/tex] or
[tex]a_{n} = \frac{8}{2^{n-1} }[/tex]

It looks like you're given a set
{(x, y) : y = 3x + 2}
i.e. the set of points (x, y) = (x, 3x + 2), and you're told that x is taken from the set {-2, -1, 0, 1, 2}.
When x = -2, the corresponding value of y is
y = 3•(-2) + 2 = -6 + 2 = -4
What is the value of a if 3(a − 5) = 2(a +5)?
Answer:
a= 25
Step-by-step explanation:
STEPS FOR SOLVING LINEAR EQUATION
3(a−5)=2(a+5)
Use the distributive property to multiply 3 by a−5.
3a−15=2(a+5)
Use the distributive property to multiply 2 by a+5.
3a−15=2a+10
Subtract 2a from both sides.
3a−15−2a=10
Combine 3a and −2a to get a.
a−15=10
Add 15 to both sides.
a=10+15
Add 10 and 15 to get 25.
a=25

Hi pls help me guys help me this is my last chance pls guys help Use the data in the table to estimate the likelihood that a person has each eye
color. Which statement is not true?
Answer:
C. The likelihood of having brown eyes is 35%
Step-by-step explanation:
Add the total number of people, which gives you 50.
To find the percent of brown-eyed people out of 50, divide 35 by 50, then multiply the result (0.7) by 100 to get 70%.
70% of people are brown-eyed, thus, C is a false statement.
Answer:
the answer is C

the brown eyes would be 70 percent actually
