ore on the final exam (from 0 to 100%). The professor chooses a random sample of students in Introduction to Chemistry and collects data about each student’s final exam score and number of missed days of class. Which of the following is the most appropriate statistical test to use to determine if there is a relationship between number of missed classes and final exam scores?

Answer:

Interference for regression

Explanation:

Interference for regression is the most suitable statistical test to use to find out if there is any link between number of missed classes and the final test scores.

Because those two variables are related and student test score can be predicted using number of classes that are missed.

The base price of the car is about $22,196 because:

x= major options package

10x + x = 24,416

*the 10x is the price of the car

This then simplifies to

11x = 24,416 

use division.

The destination charge is not needed unless you want to check your answer. If you have to then you would do the same thing. The equation would be:

y= destination charge

5y + y = 24,416

Hope this helps.

The initial population of a town is 3600​, and it grows with a doubling time of 10 years. What will the population be in 8 ​year
shutvik [7]
If is doubles in 10 years, then you should divide 2 by 10 to get the yearly growth rate equaling 1/5. Multiply 1/5 by 8 equals 8/5= 1 3/5. multiply that number by 3600, giving you 5,760.

Malachy, Sushil and Fiona share some sweets in the ratio 7:1:1. Malachy gets 90 more sweets than Fiona. How many sweets does Sus
VashaNatasha [74]

Answer:

15

Step-by-step explanation:

Fiona (F) = Sushi (S)

Malachy (M) = 7 Fiona (F)

M = F + 90

F + 90 = 7F

6F = 90

F (Fiona) = 15

S (Sushi) = 15

check: Malachy (M) = 15 * 7 = 105

M-F = 105 - 15 = 90

Classify the model as Exponential GROWTH or DECAY. <br> A=10(1.01)^3
Masteriza [31]

Answer:

GROWTH

Step-by-step explanation:

Given the Exponential function;

A=10*1.01^{3}

As we can see in the given function above:

the base number is 1.01 which is greater than 1 hence the quantity increases,

slowly at first and then very rapidly over its domain. The rate of growth becomes faster as time passes.

The growth "rate" (r) is determined as b = 1 + r.

In this situation, the rate growth is = 1.01 -1  = 0.01

Hope it will find you well.
