Answer:
When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is transformed into its opposite. When working with the graph of y = f (x), replace x with -x. Reflection in y = x: When you reflect a point across the line y = x, the x-coordinate and the y-coordinate change places.
6.

since

feet. Then 6*4=24 So the answer is C
7. 1200 m/8 cm = C. 1 cm = 150 m
8. A. Since 1 in = 3 feet then 6 inches = 18 feet (6*3=18) and 4 inches = 12 feet (4*3=12) so the dimensions of her room are 16'x12'.
B. A=lxw so 16*12= 216

Hope that helps

Step-by-step explanation:
Answer:
A)0.8533
Step-by-step explanation:
For each person, there are only two possible outcomes. Either they are 65 or older, or they are not. The probability of a person being 65 or older is independent of any other person. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

In which
is the number of different combinations of x objects from a set of n elements, given by the following formula.

And p is the probability of X happening.
14 percent of the population of Arizona is 65 years or older.
This means that 
A random sample of five persons from this population is taken.
This means that 
The probability that less than 2 of the 5 are 65 years or older is :

In which




So the correct answer is:
A)0.8533
