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:
y=2/7x+2.5
Step-by-step explanation:
Answer: who ever arrives at the answer x=0/3 =0 is correct
Step-by-step explanation:
Even though I need supporting details from the individual answers of Jane and Jill to pass my own judgment.
Given the expression
(2x²+x) +2(-x²+×)=0
Let's us open the bracket
2x²+x-2x²+2x=0
Collecting like terms
2x²-2x²+x+2x=0
3x=0
x=0/3
x=0
Answer:
28∛3+72
Step-by-step explanation:
distribute: 28∛3+24∛3∛9 - be careful, ∛9 is not equal to 3! You are looking for three "copies" of a number since it is a ∛ not √.
28∛3+24∛(3*9)=28∛3+24*3 = 28∛3+72
