Answer:
77.112
Step-by-step explanation:
circle area A=pirsquared so A= 3.142×6×6= 113.112
rectangle area A= 6×6=36
shaded area= 113.112-36=77.112
The set-up 25/100= 50/? is incorrect.
The correct set-up should be ?/50= 25/100.
?= 50* (25/100)= 12.5.
The correct answer is 12.5~

Step-by-step explanation:
x + y = 10 - - - 1
x=2y - - - - - 2
Putting the value of x in eqn 1,
2y+y=10
y=10/3

The z-scores that are the cutoffs are given as follows:
a. z = 1.645.
b. z = -1.96.
c. z = -0.51.
d. z = 0.
e. z = 0.
<h3>What is the z-score formula and what does it represent?</h3>
The z-score of a measure X of a variable that has mean given by and standard deviation represented by is given as follows:
- The z-score measures how many standard deviations the measure X is above(in case the score is positive) or below(in case the score is negative) the mean.
- From the z-score table, the p-value associated with the z-score is found, which represents the percentile of the measure X.
For this problem, we have that:
- In item a, the cutoff is the 95th percentile, hence z = 1.645, which has a p-value of 0.95.
- In item b, the cutoff is the 2.5th percentile, hence z = -1.96, which has a p-value of 0.025.
- In item c, the cutoff is the 30.5th percentile, hence z = -0.51, which has a p-value of 0.305.
- In item d, the cutoff is the 50th percentile, hence z = 0, which has a p-value of 0.5.
- In item e, the cutoff is the 50th percentile, hence z = 0, which has a p-value of 0.5.

S=f+60
J=Fx2-50
Senior=fx3
(f)+(f+60)+(fx2-50)+(fx3)=1424 (Parenthesis first)
f+f+60+2f-50+3f=1424 (rewrite)
2f+60+2f-50+3f=1424 (combine like variables)
7f+10=1424 (rewrite)
7f=1414 (isolate variable (take away 10 from each side))
