8(j - 4) = 2(aj - 16)
4(j - 4) = aj - 16
4j - 16 = aj - 16
4j = aj
4j - aj = 0
j(4 - a) = 0
j = 0
The answer is: j = 0.
Answer: 0.02
Step-by-step explanation:
Given: Sample size : ![n= 525](https://tex.z-dn.net/?f=n%3D%20525)
The population proportion ![P=0.3](https://tex.z-dn.net/?f=P%3D0.3)
Then,
The formula to calculate the standard error is given by :-
![S.E.\sqrt{\dfrac{PQ}{n}}](https://tex.z-dn.net/?f=S.E.%5Csqrt%7B%5Cdfrac%7BPQ%7D%7Bn%7D%7D)
![\Rightarrow\ S.E.=\sqrt{\dfrac{0.3\times0.7}{525}}=0.02](https://tex.z-dn.net/?f=%5CRightarrow%5C%20S.E.%3D%5Csqrt%7B%5Cdfrac%7B0.3%5Ctimes0.7%7D%7B525%7D%7D%3D0.02)
Hence, the standard deviation of the sample proportions (i.e., the standard error of the proportion) is <u>0.02</u>.
-1/27

Answer:
-7/8
Step-by-step explanation:
y = 1/8 -1
y = 1/2^3 -1
y = 1 - (2^3)/2^3
y = 1-8/2^3
y = 7/2^3
y = -7/8

Answer:
75
Step-by-step explanation:
Since its a right triangle you would use the Pythagorean Theorem. 60 sqaured is 3600, and 45 squared is 2025. Add those together to get 5625. The sqaure root of 5625 is 75
