Answer:
D
Step-by-step explanation:
I usually use a z-score table, but you can do this with a calculator.
If we go to a z-score table, we first look up the first two digits (in this case, 2.8) in the far left column. Then we find the hundredths digit in the top row (0.07). Where they intersect is P(z < 2.87).
P(z < 2.87) = 0.9979
Answer D.
Answer:
f(-1) = 12
f(1) - g(1) = 8
g(x) = 4 when x = 2
f(x) = g(x) when x = 3
Step-by-step explanation:
Read the graph.
Find the x - values on the x - axis and identify what y level the line is at.
The total price of the cinnamon with tax is $4.61
Step-by-step explanation:
Cost of the cinnamon= $4.25
Tax = 8.625%
Total price of the cinnamon= 4.25 + (8.625% of 4.25)
= 4.25 + (8.625/100) 4.25
= 4.25 + (0.36)
= $4.61
The total price of the cinnamon with tax is $4.61
Answer:
f(x)=x² , g(x)= x+1. f(g(2))?
g(2)
2+1=3
g(2)=3
f(3)
3²=9
f(3)=9
the answer is 9
