Answer:
Standard error = 0.83
Step-by-step explanation:
Given that the heights in inches of males in the united states are believed to be approximately normally distributed with mean u
Sample mean for 25 adults randomly taken =
inches
Std deviation of sample s =
inches
Since X the height of males is Normal we find that the sample mean also will follow a normal distribution.
By central limit theorem, mean of x would be= sample mean= 69.72
Std error = 
Standard error of the mean = std dev/square root of sample size.
Here only sample std deviation is known
So we used it
Standard error = 0.83
Answer:
B is the answer
Step-by-step explanation:
-3(2w+6)-4
-6w-18-4
-6w-22
Let ticket be x and meal be y
So $0.50 for each movie ticket = 0.50x
$2 for each meal = 2y
He purchased 22 tickets, so x = 22
0.50 * 22 = $ 11
Now the total value is $25 (with both ticket and meal)
total = t
0.50x + 2y = t
you know x = 22 and t = 25
11 + 2y = 25
Part A)
2y = 25 -11
y = 14/2
y = 7
Number of meal is 7
Part B)
(don't know about part B)
0.50x + 2y = 25
0.50(22) + 2(7) = 25
11 + 14 = 25
25 = 25
