Answer: 650
Step-by-step explanation:
When prior estimate of population proportion is known , then the formula to find the required sample size is given by :-

, where p= population proportion
E= margin of error
z* = Critical value.
Let p be the proportion of adults able to identify a Toyota Scion by brand and model name.
As per given , we have
p = 12%= 0.12
E= 2.5%=0.025
Critical value for 95% confidence interval : z* = 1.960 [By z-table ]
Then, the required sample size = 



Thus , the required sample size = 650
Answer:
There is a 0.36% Chance of 1 or fewer in every 24 matches being flawed.
Step-by-step explanation:
Firstly we need to know what 1/10 of 5 is. It is 0.5.
You then need to multiply 24 by 1.5 to get 36. We then need to divide that by 100 to get a percentage and we end up with 0.36%
Here is an explanation of how to get percentages: https://www.mathsisfun.com/converting-fractions-percents.html
(x^a)(x^b)=x^(a+b)
(ab)(cd)=(a)(b)(c)(d)
x^-m=1/(x^m)
(3y^-4)(2y^-4)=
(3)(y^-4)(2)(y^-4)=
(6)(y^-8)=
6/(y^8)
So you swap sides and you have 3x=93 and then you divide 3 by 93 and you get x=31
S = m+6
(s + 3) = (m + 3)1.5
When solved m=9 and s=15
When plugged in it works.
So max is 9 years old
