Olivia family drove to Disney land For spring break. Her mom and dad shared the driving duties for a total of 14 hours. her mom
Kay [80]

Mom drove for 11 hours.

Dad drove for 3 hours.

<u>Step-by-step explanation</u>:

  • Total hours = 14 hours
  • Total distance = 895 miles
  • Mom drove a speed of 65 mph
  • Dad drove a speed of 60 mph

Let 'x' be the number of hours drove by mom.

Let 'y' be the number of hours drove by dad.

x + y = 14     ---------------(1)

65x + 60y = 895  ---------(2)

Multiply eq(1) by 60 and subtract eq(2) from (1),

60x + 60y = 840

-(<u>65x + 60y = 895</u>)

 <u> -5x   = -55    </u>

x = 55/5

x = 11

∴ Mom drove for 11 hours.

Substitute x=11 in eq(1)

11+y = 14

y = 3

∴ Dad drove for 3 hours.

You believe that eating an apple a day is healthy and want to design an experiment to find out. You have available 40 volunteers
Gwar [14]

The best design for this experiment would be a repeated measures design. This is ideal to determine if eating an apple makes you healthy.

<h3>What is an experimental design?</h3>

An experimental design refers to the general structure of an experiment including how people are distributed into the control and experimental group to test a specific phenomenon.

<h3>What is a repeated measures design?</h3>

In a repeated measures design all participants are both parts of the control group, in this case, people who do not eat apples, and the experimental group, or people who eat apples.

<h3>What does this design imply?</h3>

In the case of determining if eating an apple every day, this design implies:

  • All participants will be asked to not eat apples every day for a specific period such as one or two months, and health levels will be measured during this time.
  • After the first step, all participants will be asked to eat an apple every day during the period, and their health will be measured.
  • The researcher can compare the results of each participant, which is more accurate than comparing one participant to another.

Question 2.what is the probability that between 80 and 115 complaints are received in one week? use a n(110,20) model to approxi
AURORKA [14]

Calculate standard  Z values for the given data:-

z = (80 - 110) / 20 = - 3/2 = -1.5

and z = (115 - 110) / 20 =  0.25

so we need  Prob ( -1.5 < z < 0.25)

Using standard tables this  comes to 0.5319  Answer
