One question in the survey asked how much time per year the children spent in volunteer activities. The sample mean was 14.76 hours and the sample standard deviation was 16.54 hours.Required:a. Based on the reported sample mean and sample standard deviation, explain why it is not reasonable to think that the distribution of volunteer times for the population of South Korean middle school students is approximately normal. b. The sample size was not given in the paper, but the sample size was described as large. Suppose that the sample size was 500. Explain why it is reasonable to use a one-sample t confidence interval to estimate the population mean even though the population distribution is not approximately normal. c. Calculate and interpret a confidence interval for the mean number of hours spent in volunteer activities per year for South Korean middle school children.

What is the y-coordinate of the point that divides the directedline segment from J to K into a ratio of 2:3?

K(8,11)

J(-3,1)

*7

*-6

*5

*-5

Answers

Answer:

(D)5

Step-by-step explanation:

Given the point J(-3,1) and K(8,11).

The line segment that divides the segment from J to K in any given ratio can be determined using the formula.

$P(x,y)=\left((mx_2+nx_1)/(m+n) ,(my_2+ny_1)/(m+n)\right)$

In the given case:

$(x_1,y_1)=(-3,1), (x_2,y_2)=(8,11)$ , m:n=2:3

Since we are to determine the y-coordinate of the point that divides JK into a ratio of 2:3, we have:

$(my_2+ny_1)/(m+n)=(2*11+3*1)/(3+2)\n\n=(22+3)/(5)\n\n=(25)/(5)\n\n=5$

The y-coordinate of the point that divides the directed line segment from J to K into a ratio of 2:3 is 5.

The correct option is D.

Remainder:

Answers

Step-by-step explanation:

254 = 8 * 30 + 8 * 1 + 6

= 8(30 + 1) + 6

= 8 * 31 + 6.

Hence the quotient is 31 and the remainder is 6.

Answer:

254/8=31.75

Step-by-step explanation:

The remainder of 254 divided by 8 is 6

Question 8A rectangle has vertices at (0,0), (3,0), and (0,6). What is the area
of the rectangle?

I’ll mark you!

Answers

Answer:

18 square units

Step-by-step explanation:

The area of a rectangle is simply it's base length multiplied by its height.

A = b × h

Since a rectangle has all right angles, it must have two sets of parallel sides.

Given the coordinates (0, 0), (3, 0), (0, 6) which are vertices of the rectangle. You can find the distance between each point to get the side length and then multiply the two side lengths together.

Peter weighs 156 pounds, but he would like to wrestle in a lower weightclass. He loses 4 pounds one week, gains back 2 pounds the next, loses 5
pounds the third week and loses 3 pounds the fourth week. How much does
Peter weigh now?

Answers

Answer:

146 pounds

Step-by-step explanation:

He starts at 156 pounds.

1st week: He loses 4 pounds, indicating 156 - 4, or 152.

2nd week: He gains 2 pounds, indicating 152 + 2, or 154.

3rd week: He loses 5 pounds, indicating 154 - 5, or 149.

4th week: He loses 3 pounds, indicating 149 - 3, or 146.
