Answer:
x = 4.5
Step-by-step explanation:
Angle B = angle C because it is an isosceles triangle.
3x32 = 87-2x
96 = 87-2x
reduce:
9 = 2x
x = 4.5
Multiply 245 by .40 (which is 40%)
245 x (.40)= 98. When you get 98, you have to 245-98 and you get 147
The computation of the data shows that the standard error is 0.015.
<h3>How to calculate the standard error?</h3>
From the information, the following can be deduced:
Number of students n = 49
Randomly selected students = 0.794
The standard error will be:
= 0.105/✓49
= 0.105/7
= 0.015
In conclusion, the standard error is 0.015.
