does anyone know the answer to this?

Answer:

A. All seventh grade students at Wood Middle School

Step-by-step explanation:

We want to find which is the population.

Now, A population is simply the entire set or group that you intend to find out information and draw up a conclusion while sample is the specific set or group derived from that population from which we collect data.

Thus implies that the population size is always more than the sample size.

In this question, from the definition we have given, we can easily see that the population is the 300 seventh grade students at Wood Middle School while the sample is is the 100 seventh grade students that were surveyed.

Answer:

20 inches

Step-by-step explanation:

A rectangular object can instead be thought about as two right triangles with the hypotenuse being the diagonal we are solving for.

With this in mind the Pythagorean Theorem can be used to solve for c

c^2=a^2+b^2

A=16 inches

B= 12 inches

C= hypotenuse

C^2=16^2+12^2

C^2=256+144

C^2=400

Take the square root of both sides: C = 20 inches

Answer:

Step-by-step explanation:

1. 7, 13, 14, 14, 16 --> 13, 14, 14 --> 14

Result/Median : 14

2. 8, 10, 13, 16, 16, 17, 20, 20 -->

10, 13, 16, 16, 17, 20 -->

13, 16, 16, 17 -->

16, 16 --> You are left with two numbers, so you find their average.

16 + 16 = 32 / 2 = 16

Result/Median: 16

Answer:

a) C = 3 + 5h

b) Slope = 5

y - intercept = 3

c) $28

Step-by-step explanation:

For babysitting, Nicole charges a flat fee of $3, plus $5 per hour.

a) Write an equation for the cost, C, after h hours of babysitting.

The equation for the cost C is given as:

C = $3 + $5 × h

C = 3 + 5h

b) What do you think the slope and intercept represent?

The equation of a straight line is represented by

y = mx + c

Where

Slope = m and y-intercept = c

Comparing this with our equation in a

C = 3 + 5h = C = 5h + 3

mx = 5h

c = 3

Therefore,

Slope = 5

y - intercept = 3

c)How much money will she make if she baby-sits 5 hours?

We have our equation above as:

C = 3 + 5h

h = 5 hours

Hence,

C = 3 + 5 × 5

C = 3 + 25

C = $28

She would make $28

Answer: 0.2 m/s

Step-by-step explanation:

The student steps on the raft, and then he moves (with the raft) at a speed of 2.0m/s to cross the flooded street.

Then the raft moves with him, at the same speed (notice that the mass of the raft does not matter, suppose that you move at 100km/h in a small car, the speed of the vehicle would be exactly the same as if you where in a truck moving at 100km/h)

Then the speed of the raft is also 2.0 m/s.

Answer:

1. State the claim H0 and the alternative, Ha

2. Choose a significance level or use the given one.

3. Draw the sampling distribution based on the assumption that H0 is true, and shade the area

of interest.

4. Check conditions. Calculate the test statistic.

5. Find the p-value.

6. If the p-value is less than the significance level, α, reject the null hypothesis. (There is enough

evidence to reject the claim.)

If the p-value is greater than the significance level, α, do not reject the null hypothesis.

(There is not enough evidence to reject the claim.)

(You can use the p-value to make a statement about the strength of the evidence against H0

without using α, e.g., p>.10 implies “little or no evidence against H0”, .05< p ≤ 10 implies

“some evidence against H0”, .01 < p ≤ .05 implies “good evidence against H0”, .001 < p ≤ .01

implies “strong evidence against H0”, p ≤ .001 implies “very strong evidence against H0”.)

7. Write a statement to interpret the decision in the context of the original claim.

Answer:

30 tiles need to buy for same cost in both store.

Step-by-step explanation:

Let x be the number of tiles to buy for same cost in both store.∴18+0.69⋅n=1.29⋅n∴ 1.29n − 0.69n = 18 or 0.6n =18∴n=180.6=30 Therefore, 30 tiles need to buy for same cost in both store

Answer:

first * can be any number greater than 6

second * can be any number larger than 16

Step-by-step explanation:

take each part alone:

multiply by 24 in both sides → * > 6

multiply by 4 in both sides → 1 > 16/*

take * to first side → * > 16

there is no specific answers you can go with 8 and 18

Answer:

P = -5

Step-by-step explanation:

First try to get the variable p by its self and the whole numbers on the opposite side.

14p - 8 = 22 + 20p

-14p                - 14 p

-8 = 22 + 6p

-22  -22      

-30 = 6p

Then divide to get P alone

-30 = 6p

/6        /6

-5 = p

Answer:

x = 4/3

Step-by-step explanation:

7x − 4 + 8x = 6x + 8

Answer:

x=[tex]\frac{4}{3}[/tex]

Step-by-step explanation:

So the equation is 7x-4+8x=6x+8. All we need to do is simplify. On the left side, 7x+8x=15x, so 15x-4=6x+8. Now, we bring the 6x from the right side to the left. When you bring a term from one side to another, you change its sign. As of now, the sign of 6x is positive, so we make it negative and move it to the left side. The new equation is 15x-6x-4=8. Simplifying the left side gives you a new equation of 9x-4=8. Now we move the -4 from the left side to the right side. We change the sign so it becomes 4 and we move it to the right. The equation is now 9x=8+4. 8+4=12, so the final equation is 9x=12. Now we divide by 9 on both sides, giving us the unsimplified answer of x= [tex]\frac{12}{9}[/tex]. We divide the numerator and the denominator by 3 and we get our final answer of x=[tex]\frac{4}{3}[/tex].
