Answer:
M = 5K/2G
Step-by-step explanation:
In order to solve for M, we'll need to cross-multiply. This means that we create an X looking figure. Leaving us with 5K = 2G(M). Next, in order to solve for M, we'll need to divide both sides by 2G. Therefore, M = 5K/2G.
Answer: (0.881, 0.919)
Step-by-step explanation:
Let p be the population proportion of respondents who say the Internet has been a good thing for them personally.
Confidence interval for population proportion is given by :-
, where z* = Critical value ,
= Sample proportion
n = sample size.
As per given , we have
n= 957
By z-table , Critical value for 95% confidence interval : z*= 1.96
Then, the 95% confidence interval for the proportion of respondents who say the Internet has been a good thing for them personally. will be :
Hence, the required 95% confidence interval for the proportion of respondents who say the Internet has been a good thing for them personally = (0.881, 0.919)
Answer:
1. 24
2. B
Step-by-step explanation:
1. 7^2+x^2=25^2
49+x^2=625
x^2=576
x=24
2. 15^2+36^2=39^2
225 + 1296 = 1521
First you need to make 37/6 into a mixed number or a decimal
37/6=6.16 or 6 1/6
To make 6.16 or 6 1/6 into 6 you need to subtract .16 or 1/6
1/6=.16 by the way.
