Answer:
21
Step-by-step explanation:
so the relationship is that the music is ten times the commercials so, divide 210 by 30 and times that number by 3 210/30= 7, 7'3=21
Answer:
y = 9
Step-by-step explanation:
Using the sine ratio in the right triangle and the exact value
sin45° =
sin45° = =
Multiply both sides by y
y × sin45° = 9, that is
y × = 9
Multiply both sides by
y = 9
Set everything to 11
11 is your f(x)
11=2x+5
Solve for x, subtract 5 on both sides and you get
11-5=2x
6=2x Now divide by two on both sides
x=3
Answer:
#10) What is the rate of change of y with
respect to x of the table?
B.-5
The probability is about 85.29%.
To do this, you need to first find the z-score on each end of the interval. Then, you can subtract the percents to find the percent in the middle.
Lower:
(1000 - 1252) / 129 = -1.18 which gives a probability of 11.9%
Upper:
(1500 - 1252) / 129 = 1.92 which gives a probability of 97.19%
97.19 - 11.9 = 85.29
