Jacob earns $7.25 an hour at his part-time job, and earns $9 each time he mows the lawn for his mother. He graphs the amount of

olchik [2.2K]

Answer: $7.25 at part-time job

$9.00 every time lawn mowed

so he would get 33.33 day so we will just say 33 times to get 300 dollars if he gets $9 for mowing. And 41.37 hours to get $300 and he would have to use x and y graph to find the boundary line.

How many degrees does the hour hand move from 3:00 to 5:30?

hodyreva [135]

now, keeping in mind that a circular clock has 360° total, and there are 12 hours labeled on it evenly, so the angle between each hour label is 360 ÷ 12 = 30.

so, from 3pm to 5pm, it moved by 30° + 30° = 60°.

from 5pm to 5:30, that's only half an hour, so it moved half 30°, or 15°.

60° + 15° = 75°.

You draw samples of size n from the population of all pennies in circulation. The random variable of interest is the mean age of

inn [45]

Answer:

Answers explained below

Step-by-step explanation:

Let X be the random variable that ages of pennies.

Also given that distribution of X is skewed to the right.

Given that,

mean = 7.4 years

standard deviation, sd = 3.3 years

Discuss the mean, standard deviation, and shape of the sampling distribution of sample means of the ages of pennies for each of the given sample sizes.

For n = 5,

the mean of the sampling distribution of mean = 7.4

sd of the samplong distribution of mean = 3.3 / sqrt(5) = 1.48

Shape of the distribution is positively skewed.

For n= 15

the mean of the sampling distribution of mean = 7.4

sd of the samplong distribution of mean = 3.3 / sqrt(15) = 0.85

Shape of the distribution is positively skewed.

For n = 40

the mean of the sampling distribution of mean = 7.4

sd of the samplong distribution of mean = 3.3 / sqrt(40) = 0.52

Shape of the distribution is bell shaped or normal distribution.
