Step-by-step explanation:

Explanatory variable is controlled by the researcher for the given experimental study. The researcher can put some conditions on the variable and the results are calculated. Hence, it is clear that result of the manipulated variable is noted and the manipulated variable is known as explanatory variable. There could be more than one explanatory variable.

For example consider the variables number of hours spent in practicing for a sport and the result in that sport. Here, the number of hours spent practicing influences the performance of the athlete. Hence, the variable number of hours spent is known as explanatory variable.

Also, there is one major difference between an independent variable and explanatory variable. The independent variable is not affected by other independent variables whereas for the explanatory variables, the variables are not independent.

Alona [7]

Answer:

X is a discrete random variable.

X can take values from 0 to 12:

$X\in[0,1,2,3,4,5,6,7,8,9,10,11,12]$

Step-by-step explanation:

(a) X = the number of unbroken eggs in a randomly chosen standard egg carton

X is a discrete random variable.

The minimum amount of eggs broken is 0 and the maximum amount of eggs broken is 12 (assuming a dozen egg carton).

Then, X can take values from 0 to 12:

$X\in[0,1,2,3,4,5,6,7,8,9,10,11,12]$

About the probability ditribution nothing can be said, because there is no information about it (it can be a binomial, uniform or non-standard distribution).

A pizza shop sells pizzas that are 10 inches (in diameter) or larger. A 10-inch cheese pizza costs $8. Each additional inch cost

zaharov [31]

Answer:

8 + 1.50x + 0.75y = 19.25

Step-by-step explanation:

Let the number of additional inch = x

Let the number of toppings = y

From the question,

A 10-inch cheese pizza costs $8.

Each additional inch costs $1.50

Each additional topping costs $0.75.

The equation that represents Josh's pizza is when his total cost amounts to $19.25 is:

$8 + $1.50 × x + $0.75y = $19.25

8 + 1.50x + 0.75y = 19.25
