People tend to evaluate the quality of their lives relative to others around them (Frieswijk et al., 2004). In one study, researchers conducted interviews with n = 9 frail elderly people. During the interview, each person was compared with a fictitious person who was worse off than the elderly person. The scores below are the measures from a life-satisfaction scale for the elderly sample. Assume that the average score on this scale in the population is u = 20. Are the data sufficient to conclude that the elderly people in this sample are either significantly more or less satisfied than others in the general population? The life-satisfaction scores for the sample are 18, 23, 24, 22, 19, 27, 23, 26, 25. a. Which kind of t-test should you use? b. How many tails should the test have?

Cameron bought a used car for $4,500. He made a down payment of $1,200 and agreed to pay the remaining balance in monthly payments of $300 each.Which equation can be used to find m, the number of months it will take Cameron to pay off his car? (7.10A)

F 4,500 = 1,200 + 300m
F 4,500 = 1,200 + 300m

G 4,500 = –300 + 1,200m
G 4,500 = –300 + 1,200m

H 4,500 = 300 + 1,200m
H 4,500 = 300 + 1,200m

J 4,500 = 1,200 – 300m
J 4,500 = 1,200 – 300m

Answers

Answer:

$4500 = 1200 + 300m$

Step-by-step explanation:

Given

$Total = 4500$

$Base\ Amount = 1200$

$Payment = 300$ monthly

Required

Write an expression to determine the number of months

The total can be expressed using:

$Total = Base\ Amount +Payment * Number\ of\ months$

Substitute value for each term

$4500 = 1200 + 300 * m$

$4500 = 1200 + 300m$

Hence:

Solve the equation x/4 - 7 = y for x

Answers

Answer:

x = 4y + 28

Step-by-step explanation:

x/4 - 7 = y

+7 +7

x/4 = y + 7

× 4 × 4

x = 4y + 28

Answer:

x = 4y + 28

Step-by-step explanation:

For this, you would need to simplify both sides of the equation, after isolating the variable.

Why do people utilise coordinate geometry?

For the purpose of connecting algebra and geometry with the aid of line and curve graphs, coordinate geometry is necessary. Finding points on a plane is a crucial component of mathematics. It also has a number of uses in other scientific fields such dimensional geometry, calculus, and trigonometry. Use y=-2x in place of x in the first equation:

5x - 9(-2x) = -46

Simplify and find x's value:

5x + 18x = -46

23x = -46

x = -2

We can use the second equation to get y now that we know the value of x:

y = -2x = -2(-2) = 4
