Answer: 
Step-by-step explanation:
The mean and standard deviation of the sampling distribution of p is given by :-

, where p= population proportion.
n= sample size.
Let p represent the sample proportion of Americans over the age of 65 that were male.
Given : The proportion of Americans over the age of 65 were male.
p= 43.1%=0.431
sample size : n= 60
Then, the mean and standard deviation of the sampling distribution of p will be :-

Hence, the mean and standard deviation of the sampling distribution of p :

Answer:
42 cm ^2
Step-by-step explanation:
The area of a triangle is 1/2 B x H ( one half base times height)
The base is 6 cm and the height is 14 cm. So the full equation now is
1/2 (6) (14)
First you multiple 6 times 14 which is 84. Next you just divide it by 2 because 1/2 is half of the number. 84 divided by 2 is 42. So your answer is
42 cm ^2 (centimetres squared)
-7 + 7 = 0
-5y = 2x
-5y/5 = y
2x/5 = 2x/5
y = 2x/5
4y = -3x + 7
4y/4 = y
-3x/4 + 7/4
y = -3x/4 + 7/4
