Answer:
A
Step-by-step explanation:
When an opinion poll selects cell phone numbers at random to dial, the cell phone exchange is first selected and then random digits are added to form a complete telephone number. When using this procedure to generate random cell phone numbers, approximately 55%55% of the cell numbers generated correspond to working numbers. You watch a pollster dial 1515cell numbers that have been selected in this manner.What is the mean number of calls that reach a working cell number?A. 0.550.55B. 1515C. 8.258.25D. 3030
Answer:
303.63 sq inches
Step-by-step explanation:
We need to find the area of the two rectangles he cuts and add them together.
The area of a rectangle is given as:
A = L * B
The first rectangle is 16 inches × 12 1/4 inches. Its area is:
A = 16 * 12 1/4 = 16 * 49/4 = 196 sq inches
The second rectangle is 10 1/2 inches by 10 1/4 inches. Its area is:
A = 10 1/2 * 10 1/4 = 21/2 * 41/4 = 107.63 sq inches
The total square inches of construction paper that he needs is:
196 + 107.63 = 303.63 sq inches
Answer:
The answer is given below
Step-by-step explanation:
Q1: How are rational exponents and radicals related?
Rational exponents are exponents in fraction form. Radicals are roots (square root, cube root and so on).
The denominator of the rational exponent is the root which is the same as the radical.
Q2: How can the average rate of change be identified for a function?
The average rate of change is ratio of the change in output to the change in input values. The average rate of change for a function is the slope of the function.
It can be gotten by finding the first derivative of he function.
Q3: How do linear and exponential functions compare as the domain increases?
For linear functions as x increases, y also increases by the same amount (i.e rate of change is constant). For exponential function the rate of change increases by a factor known as the multiplier.
Given is -
The variables y and x have a proportional relationship, and y = 5 when x = 4.
As we have to find the value of x when y= 8 so putting y = 8 in the above relationship, we get :
Hence, the answer is 6.4
