Answer:
1.) .399
2.) {.369, .429}
Step-by-step explanation:
The proportion of criminals in this sample that were caught was
=.39944, .399 rounded to three decimal places.
To construct the confidence interval, you need three pieces of information: the statistic, the critical value, and the standard error.
The statistic is given in the first part of the problem with the proportion of criminals in the sample that were caught was .399.
The critical value, we are told, is the z equivalent of 90%, or 1.645. You can find this value using a z table or with the inverse normal function on a calculator.
Finally, we need the standard error. The formula for standard error for a proportion with a single population is
so in this situation it would be
=.0183.
The confidence interval would be .399±.018×1.645 or .399±.030 {.369, .429}

Hope this helps dude
Answer:
(f/g)(8) = -169
Step-by-step explanation:
Simply plug in <em>x </em>= 8 into our equation:


-13(13)
-169
Answer:
x =12
Step-by-step explanation:
The two angles are complementary, so the add to 90 degrees
5x+1/2x +24 = 90
Combine like terms
5 1/2 x +24 = 90
Subtract 24 from each side
5 1/2 x = 90-24
Change the mixed number to an improper fraction
11/2 x = 66
Multiply by the reciprocal 2/11 on each side
2/11 *11/2 x = 66*2/11
x = 6*2
x =12
Answer:
2: x=6
3: x=5
Step-by-step explanation:
Question 1 is answered in the picture, but the answer is 6
<h2>Question 2:</h2>
x=14.3-(6.3+2)
x=14.3-8.3
x=6
<h2>Question 3:</h2>
x=20.6-(8.6+7)
x=20.6-15.6
x=5
