When it says per month, it means to multiply. In this case, the expression would be;
25x+50
So however many months Fatima has spent at the gym, you would multiply that times 25 and add the initiation fee. Hope this helps.

Find the pattern
z,Y,x,W,v,U
The letter from the end of the alphabet are skipped every letter
a,B,c,D,e,F
The pattern is the same as the end of the alphabet
Therefore, the next letter would be S as we have to skip one from U, this being T.
Answer:
The 90% confidence interval would be given by (63.330;81.070)
Step-by-step explanation:
A confidence interval is "a range of values that’s likely to include a population value with a certain degree of confidence. It is often expressed a % whereby a population means lies between an upper and lower interval".
The margin of error is the range of values below and above the sample statistic in a confidence interval.
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
Let put some notation
x=left arm , y = right arm
x: 175 169 182 146 144
y: 102 101 94 79 79
Since the Confidence is 0.90 or 90%, the value of a = 0.1 and a/2= 0.05we can use excel, a calculator or a table to find the critical value. The excel command would be: "=-T.INV(0.05,4)".And we see that ta/2= 2.13
Answer:
f(x)could also be written as y in y= mx+ c
by taking two points we are gonna calculate.
(0,1), (4,-1)
finding m
y*- y'/x*-x'
=1-(-1)/0-4
=2/-4
=-2
now c ( intercept)
take any point
eg. (0,1)
y=mx+c
1=-2×0+c
1=c
equation then equals to
y=-2x+1
f (x) =-2x+1
