6)The experimental probability is 39%.(39/100(100)).

7) The theoretical probability is theoretical. This is when something should happen without taking external forces into account. Experimental probability is taking the external forces into account which is why the probability is not as clean cut.

The theoretical probability should be 33%.
The experimental probability is actually 39%.

The cost of renting roller blades is $4 plus $3.50 for each hour that the roller blades are rented. Write an expression to repre
Pavel [41]

Answer:

The expression is equal to 3.50h+4

Step-by-step explanation:

Let

x ----> the number of hours that the roller blades are rented

y ----> the cost of renting roller blades in dollars

we know that

The linear equation in slope intercept form is equal to

y=mx+b

where

m is the slope or unit rate of the linear equation

b is the y-intercept or initial value of the linear equation

In this problem we have

The slope is equal to

m=\$3.50\ per\ hour

The y-intercept is equal to

b=\$4 ----> value of y when the value of x is equal to zero

substitute

y=3.50x+4

For x=h hours

substitute

y=3.50h+4

Identify the maximum or minimum value and the domain and range of the graph of the function y = 2(x – 3)2 – 4.
NISA [10]
We are given the equation y = 2(x – 3)^2 – 4 and is asked for the domain and range of the following function. In this case, there is no radical sign so the domain includes all real numbers. The range has a minimum value of -4 since the squaring makes the value on the first term positive. Hence the answer is A.
