Consider these sample means for the number of weekend hours spent studying for a Monday exam.

A 2-column table with 2 rows. Column 1 is a labeled Sample with entries 1, 2, 3, 4. Column 2 is labeled Sample Mean with entries 8, 5, 6, 4.

Which statements are true? Check all that apply.
The variation in the sample means is less than 5.
The variation in the sample means makes population predictions invalid.
The actual population mean most likely will be between 4 and 8.
The sample means can be used to make predictions about the population mean.
The population mean is greater than 8.
Can someone please explain how you got the answer. Will give brainlest if explained

Answer:

G, 113.04

Step-by-step explanation:

To find the area of the head of the nail you need to use the*

> A= π*r^2* A equals area, π equals pi(3.14) and then you square your raidius, which is 6 in your case.

π*r^2

plug in your six as the *r

π*6*^2

solve 6^2=36 and multiply that by your π which is 3.14

3.14*36

=113.04

Hope that helped!! :)

Answer:

18.58 cm

Step-by-step explanation:

8^2 - 6^2 = sqrt 28

sqrt 28 = 5.29

8 + 5.29 + 5.29 = 18.58

I think it’s supposed to be

1x25=25

5x5 =2

I don’t know if im right though I can’t really remember ratios

I believe 80 percent of 25 is 20.

If this is incorrect, please don't refrain to tell me, and I can edit this answer.

Answer:

A I think

Step-by-step explanation:

I dont really get the question so im not sure

Answer:

C.

Step-by-step explanation:

The question states that a LINE is reflected, just with this information we know that A. is incorrect because it is curved.

At first, when looking at B., it seems as though it could work, until you notice that it starts somewhere, but doesn't end, thus it is not a LINE. So, we can count B as incorrect as well.

When looking at C, it it a straight line, and has a beginning and and end, which means that so far, it is the most likely the line.

Then, we look at D. When looking at D, we can tell that it is a straight line, however, it has no beginning and no end, thus it can't be the answer.

Now, we know that C is the only possible answer for this question.

Answer:

a = -5

Step-by-step explanation:

a = 1/2(-10) + 3^2 - (-1) - 10

a = -5 + 3^2 - (-1) -10

a = -5 + 9 - (-1) - 10

a = 4 - (-1) - 10

a = 4 + 1 - 10

a = 5 - 10

a = -5

x = -1y = 3

z = -10

a = -5

Answer:

-7

Step-by-step explanation:

(x²+6x-16)(x-2) = x³+4x²-28x+32

x³+4x²-28x+32 = ax³+bx²+cx+d

a=1; b=4; c= -28; d= 32

-28/4 = -7

Step-by-step explanation:

First, I had to find the total number of dinners, next I had to find how many had prices of "$30 or more." Last, I had to find the total number of dinners who had prices of less than $30.

Total: 10

Less than 30: 3

10 - 3 = 7

7 = Prices of Dinners ($30 or more)

Step-by-step explanation:

The opinion of Aiden about equivalent expressions always having the same number of terms is; Not correct

Aiden is not correct with his assertion as we will see for four major operations.

We can see that in both cases the expressions have equivalent answers but the number of terms are not the same.

Same scenario also applies for division and subtraction. Thus, we can say that Aiden is not correct.

Answer:

years 1–4: 62.4 bass per year

years 5–8: 67.6 bass per year

Step-by-step explanation:

If the population in year n is ...

 p(n) = 3000·1.02^n

then the average rate of change from year 1 to year 4 is ...

 (p(4) -p(1))/(4 -1) = 3000(1.02^4 -1.02^1)/3 = 1020·(1.02^3 -1) ≈ 62.4

The average rate of change for years 1–4 is 62.4 bass per year.

___

For years 5–8, the rate of change is similarly computed:

 (p(8) -p(5))/(8 -5) = 3000(1.02^8 -1.02^5)/3 = 1000·1.02^5·(1.02^3 -1) ≈ 67.6

The average rate of change for years 5–8 is 67.6 bass per year.
