Answer:
Mapping A
Step-by-step explanation:
To clarify this, the first box in each mapping has to go to only one number to resemble a function. Function A works because each number is going to another number once while Function B doesn't work because of the number 2 going into two numbers.

what is the probability of someone's age being anywhere from 20 years to 70 years is (B) 77%
<u>Step-by-step explanation:</u>
As Given in the question that the x-axis of a density graph represents someone's age in years
This mean the probability distribution curve of age( i.e. X is given as the graph.
Area under two values of x of a probability density curve = probability that x lies between these two values
Using the above information we know that the area under the he density graph from 20 years to 70 years is 0.77,we get that
P(20<x<70) = 0.77
Converted into percent this equals 77 %
Hence, the probability of someone's age being anywhere from 20 years to 70 years is option is (B) 77%
Answer:
Y=8x-9
Step-by-step explanation:
The equation for a slope-intercept problem is y=Mx+b. M is the slope, and B is the Y-intercept. Since the slope is 8, M=8, and B= -9 since the Y-intercept is -9.
