Sample means show a large variation because the data set has a large range. When there is a large variation in the data set, the sample means also will have a large variation. Jennie included small values in her sample, while Charles included high values.

Answer:

The data set shows a large variation. Jennie used the lowest scores in her set, Charles used the highest scores. The large variation in the means was caused by a large variation in the population.

You and a group of friends are going to a five-day outdoor music festival during spring break. You hope it does not rain during
KIM [24]

Answer:

The probability of not rain during the entire festival is 0.19

Step-by-step explanation:

The Complement Rule states that the sum of the probabilities of an event and its complement must equal 1.

In this case we have the probability of raining of each day,  we need the probability of NOT raining.  

First day= 45% chance of rain, the complement is 55%

Second day 55% chance of rain, the complement is 45%

Third day a 10% chance of rain, the complement is 90%

Fourth day a 10% chance of rain, the complement is 90%

Fifth day 5% chance of rain, the complement is 95%

To get the probability of NOT raining in the entire festival is the multiplication of all the complements.

P(not raining) = 0.55 x 0.45 x 0.90 x 0.90 x 0.95= 0.19

Carlie runs two different business. She needs to pay $100 for materials, and pay her associates $12 per hour for
Marrrta [24]

Answer:

375+12ct_c+10lt_l

Step-by-step explanation:

Carlie is running two different business.

She needs to pay:

- For the childcare business,

100$ for the materials

12$ per hour for each associate for her childcare business, so if we call:

t_c = the number of hours worked by each associate

c = the number of associates

The total cost for the childcare business is:

C=100+12ct_c (1)

- For the lawn care business,

275$ for the materials

10$ per hour for each associate for her lawn care business, so if we call:

t_l = the number of hours worked by each associate

l = the number of associates

The total cost for the lawn care business is:

L=275+10lt_l (2)

Therefore, the total expenses from both businesses is the sum of (1) and (2):

T=C+L=100+12ct_c+275+10lt_l = 375+12ct_c+10lt_l
