Answer:
The 20th percentile of coffee temperature is 155.4532 degrees Fahrenheit.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 160 degrees
Standard Deviation, σ = 5.4 degrees
We are given that the distribution of temperature of coffee is a bell shaped distribution that is a normal distribution.
Formula:
We have to find the value of x such that the probability is 0.2
Calculation the value from standard normal z table, we have,
Thus,

The 20th percentile of coffee temperature is 155.4532 degrees Fahrenheit.
Answer:
one-sixth
multiply the numerator (2) by the number of kids (3) because you are accounting for the fraction of the whole pizza. By doing this you should get 3/6. divide the denominator by the number of kids (3/3) getting you to a value of 1, and replace the denominator, making the amount of pizza one-sixth.
Distributive property states a(b+c) = ab + ac
9(10 + x) = 90 + 9x
Your answer is B. 90 + 9x.
Answer:
Investment amount after 9 years = 14715.12$
Explanation:
It is given to use continuous change function, 
Here P = Principal = 10500$
r = Rate of increase = 0.0375
t = Number of years = 9

So, investment amount after 9 years = 14715.12$
Answer:
4. -6
5. -5
6. 2
Step-by-step explanation:
4.
2x + 3 <= -9
2x <= -9 - 3
2x <= -12
= x <= -6
5.
3p + 4 > -11
3p > -11 -4
3p > -15
p > -5
6.
5x + 6 >= 16
5x >= 16 - 6
5x >= 10
x >= 2
