Answer:
1.4x10^-7
Step-by-step explanation:
For Problem 6
First we would divide the first numbers together so 7.84 / 5.6 = 1.4
We then would add the exponenites together so -3+-4=-7
Leading our awnser to be 1.4x10^-7
Is there picture cause I cant draw it but ik how to do scattered plots
Answer:
475.
Step-by-step explanation:
We have been given that for a normal distribution with μ=500 and σ=100. We are asked to find the minimum score that is necessary to be in the top 60% of the distribution.
We will use z-score formula and normal distribution table to solve our given problem.

Top 60% means greater than 40%.
Let us find z-score corresponding to normal score to 40% or 0.40.
Using normal distribution table, we got a z-score of
.
Upon substituting our given values in z-score formula, we will get:





Therefore, the minimum score necessary to be in the top 60% of the distribution is 475.
Answer:
x=28
Step-by-step explanation:
4(x-5)=92
4x-20=92
add 20 to both sides
4x=112
divide 4 on both sides
x=28
I got 20,737 but I could be wrong so I will attach my algorithm and work.
