Answer:
An interval that will likely include the proportion of students in the population of twelfth-graders who carry more than $15 is 960
Step-by-step explanation:
For example, Condition 1: n(.05)≤N
• The sample size (10) is less than 5% of the population (millions of musicians), so
the condition is met.
• Condition 2: np(1-p)≥10
• =
2
10
= .2
• 1 − = 10 .2 1 − .2 = 1.6 . This is less than 10 so this condition is not
met.
It would not be practical to construct the confidence interval.
Answer:
(-25 + 4 squared) x 7
( -25 + 16) x 7
-9 x 7
-63
Step-by-step explanation:
Should be 11 and 6 because when you add 11 and 6 you get 17 and when you subtract them you get 5
III. If E={1, 2, 3, 4, 5, 6, 7, 8, 9, 10) A=(2, 3, 5, 7), B=(1, 3, 5, 7, 9) List the following sets: a) (AUB) b) (AnB) c) AnB' d
tresset_1 [31]
Step-by-step explanation:
A u B = { 1,2,3,5,7,9}
AnB = { 3,5,7}
B' = {2,4,6,8,10}
so AnB' = {2}
(AnB) = {1,3,4,5,6,7,8,9,10}

Answer:
x = 7
Step-by-step explanation:
I reversed it for easy viewing:
(x+7)/3x = 2/3
<=> (x + 7).3 = 2.(3x)
<=> 3x + 21 = 6x
<=> 21 = 6x - 3x
<=> 3x = 21
<=> x = 7
