Answer:
The value of 14.36 lb separates the top 2% of the weekly discarded paper weights in this area.
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Normally distributed with the average of 7.95 lb and the standard deviation of 3.12 lb.
This means that [tex]\mu = 7.95, \sigma = 3.12[/tex]
Which value separates the top 2% of the weekly discarded paper weights in this area?
This is the 100 - 2 = 98th percentile, which is X when Z has a pvalue of 0.98. So X when Z = 2.054.
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]2.054 = \frac{X - 7.95}{3.12}[/tex]
[tex]X - 7.95 = 2.054*3.12[/tex]
[tex]X = 14.36[/tex]
The value of 14.36 lb separates the top 2% of the weekly discarded paper weights in this area.

⅘ y = 32. Plz help me I need this answer ASAP
Answer:
If youre looking for the value of y:
Step-by-step explanation:
4/5 y=32
y= 32/(4/5)
y=40
Answer:
Step-by-step explanation:
4/5y=32. y is a unknown number. How i solve these is i do 32 times 5 which is 160 and then 160 divided by 4 is 40. 4/5 of 40 is 32.

Find the slope of the line.
The slope of the line is ___.
Answer:
5/2
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(6-(-4))/(2-(-2))
m=(6+4)/(2+2)
m=10/4
simplify
m=5/2

Describe what happens to the exponential function when the value of "k" is
positive. *
Answer:
Step-by-step explanation:It isn’t. There are really 4 different versions of the exponential function. Positive (like the growth of money invested at 5%), negative (like the US debt constantly becoming more negative), positive decay (like the half life of a radioactive element), or negative decay ( pay half your loan amount in year 1, 1/4 in year two, 1/8 in year three, you in theory will never pay your loan completely but the debt is growing closer to zero.

help please I will give you brainliest!!
Let's solve your equation step-by-step.
10/a=15/24
Step 1: Cross-multiply.
10/a=15/24
(10)*(24)=15*a
240=15a
Step 2: Flip the equation.
15a=240
Step 3: Divide both sides by 15.
15a / 15 = 240/15
a=16

Right answer gets brainiest!
Answer:
x + 4 = 10
Step-by-step explanation:
a number: x
a number increased by 4: x + 4
a number increased by 4 is 10: x + 4 = 10
Since 4 + x and x + 4 are the same, you are correct.

Answer:
-3
Step-by-step explanation:
so you SUBSTITUTE -2 in for z
ok i think they are trying to be tricky here
so
-1 - (-(-2))
inside parentheses, the two negatives are going to cancel eachother out.
now you have
-1 - (2)
which is
-1 - 2
-1 minus 2 is -3
