Answer:

Step-by-step explanation:

1. Class A:

the median is 75;
the lower quartile is 72;
the upper quartile is 89;
the maximum score is 95.

2. Class B:

the median is 75;
the lower quartile is 70;
the upper quartile is 94;
the maximum score is 100.

A. The median score of Class A is equal to the median score of Class B (75=75). This option is false.

B. The lower quartile of Class A is greater than the lower quartile of Class B. True option (72>70).

C. The upper quartile of Class A is greater than the upper quartile of Class B. False, because 89<94.

D: The maximum score of Class A is greater than the maximum score of Class B. False, because 95<100.

Does each function describe exponential growth or decay?

Aleksandr [31]

<h3>Answer: Only first two are exponential growth function and last three functions are exponential decay functions.</h3>

Step-by-step explanation: We need to describe exponential growth or decay for the given functions.

The standard exponential function equation is

$y=a(b)^x$ .

Where a is the initial value and b is the growth factor.

Note: If value of b > 1, it would be an exponential growth and if b < 1, it would be an exponential decay.

Let us check them one by one.

$y=(1.008^{1/12}})^{12t}$ => $y=(1.008^})^{1/12\times{12t} }$

=> $y= (1.008)^t$ .

Value of b is 1.008 > 1, therefor it's an exponential growth function.

y=250(1+0.004)^t, also have b>1 therefor it's an exponential growth function.

All other functions has b values less than 1, therefore only first two are exponential growth function and last three functions are exponential decay functions.

In a causal-comparative study, what is the difference between independent variables and dependent variables? independent variabl

AlladinOne [14]

Answer: independent variables cause the effect measured in the dependent variables

Step-by-step explanation: In a causal - comparative study, the dependent variables refers to the variable whose changes is being measured or observed. The changes or alteration of the dependent variable is induced by the different values of the independent variable. In causal - comparative study, the different independent variables is assumed to have a direct impact on the output or values of the dependent variable which is measured by the experimenter. Therefore, the independent variable does not change, but causes the observed changes noticed in the dependent variable.

Please Help! Geometry!

OleMash [197]

Answer:

area = 22,272

Step-by-step explanation:

area = length * width

to calculate the width, we need the first segment using the pythagorean theorem

$87^{2} + x^{2} = 145^{2}$
