Answer: See step-by-step below.
Step-by-step explanation:
First we need to solve the equation, 16x + 16x - 1 = 10.
16x + 16x - 1 = 10
32x-1 = 10
Whatever we do on one side, we have to do on the other.
So, we will add 1 to both sides.
32x - 1 + 1 = 10 + 1
Simplify.
32x = 11
x = 11/32
So, 22x = 22(11/32)
= 121/16
= 7 9/16
Answer:
8+8
Step-by-step explanation:
Answer: We are 95% confident that the mean SPF level of sunscreen used by all Cal Poly students is between 29.0813 and 40.0187.
Step-by-step explanation:
Given : Significance level :
Sample size : n= 52 , which is a large sample (n>30), so we use z-test.
By using z-value table,
Critical value:
Sample mean :
Standard deviation :
The confidence interval for population means is given by :-
i.e.
Now, the 95% confidence interval for the ppopulation mean = . (29.0813, 40.0187)
Hence, We are 95% confident that the mean SPF level of sunscreen used by all Cal Poly students is between 29.0813 and 40.0187.
Answer:
2.06x2.06x2.06x2.06x2.06x2.06x2.06x2.06x2.06x2.06
Step-by-step explanation:
it will be multiplied in standard form which means that you will have to do it like 2.06x2.06 and so forth.
As 7•7=49 it follows that 7 is the square root of 49
