Step-by-step explanation:
There is 10 questions which in this case are the trials.
We know we can either get a question right or wrong so the two outcomes are right or wrong.
The probability that a student choose the right outcome is 1/4. since there is one right answer out of 4 chocies.choices.
Yes, the trials likelihood outcome of each outcome is the same. so it's independent
Well the formula:
V = Bh
54= 3*w*8
54= 24w
24w=54
w= 54/24
w= 2.25
Answer:
p=−37m+70130
Step-by-step explanation:
Step 1: Add -36000m to both sides.
36000m+84000p+−36000m=1962800+−36000m
84000p=−36000m+1962800
Step 2: Divide both sides by 84000.
84000p84000=−36000m+196280084000
p=−37m+70130
Answer:
28 centimeters.
Step-by-step explanation:
Let w be width of desk.
We have been given that the bases of the trapezoid are 26.5 and 30 centimeters long. The area of the desk is 791 square centimeters long.
Since the area of trapezoid is half the sum of parallel sides times its height.
, where
h= Height of trapezoid,
a and b= Length of parallel sides of trapezoid.
We have been given that the height of the trapezoid is the width of the desk.
Upon substituting our given vales in above formula we will get,




Therefore, the width of trapezoid is 28 centimeters.
