i believe its the second part thats wrong
Step-by-step explanation:
1 Distribute
−5(−2+10)=20
10−50=20
2 Add 50 to both sides of the equation
10−50=20
10−50+50=20+50
3 Simplify
Add the numbers
10x−50+50=20+50
10=20+50
Add the numbers
10x =20 + 50
10x=10
4 Divide both sides of the equation by the same term
10x = 70
10x 70
---- = ----
10 10
5 Simplify
Cancel terms that are in both the numerator and denominator
10x 70
---- = ----
10 10
70
x = ----
10
70
x = ----
10
x=7
Solution
= 7

Answer:
Step-by-step explanation:
Confidence interval for population mean is given by :-
(1)
, where = Sample mean
= Critical z-value
= Population standard deviation.
n= Sample size.
As per given , we have
n= 610
Significance level for 85% confidence :
By z-table critical two tailed z-value :
Put all values in (1) , we get
Hence, the 85% confidence interval for the mean consumption of meat among people over age 40. =
