Answer: 5(x-1)
Step-by-step explanation:
5*x = 5x
5*-1 = -5
therefore the answer is 5(x-1)

I think
Approximately 95% of bags contain between 65 and 85 potato chips.
<u>Step-by-step explanation</u>:
step 1 :
Given,
The mean, M = 75
Standard deviation, SD = 5
step 2 :
From Normal distribution,
The left side of mean is 32% = M-SD, 16% = M-2SD and 2% = M-3SD
The right side of mean is 32% = M+SD, 16% = M+2SD and 2% = M+3SD
step 3 :
Calculate for left side: M-SD = 75-5 = 70 and M-2SD = 75-10 = 65
Calculate for right side: M+SD = 75+5 = 80 and M+2SD = 75+10 = 85
step 4 :
Calculate the percentage between 65 and 85:
(M-SD) + (M-2SD) + (M+SD) + (M+2SD) = 32% + 16% + 32% + 16%
= 96 % (which is approximately 95 %)
Answer:
The temp started at 12.
Step-by-step explanation:
The temp dropped 21 degrees to -9.
Let t be the old temp.
-9 = t - 21
t = 12
Answer:
Step-by-step explanation:
The equation of a straight line in point slope form is given by:
We were given that f(-3)=16, this means that the point (-3,16) is a point on this line.
Also the slope of this line is given as m=25.
We substitute the points and the slope to get:
This simplifies to:
