Answer:
The area of the shape (trapezoid) is 55 square feet.
Step-by-step explanation:
The formula to get the area of a trapezoid is . b1 is one of the bases, b2 is the other and h is the height.
First, you need to find the average of the bases:
(15+7=22)/2=11
Then, you multiply that by the height.
11*5=55
Lastly, you add the units.
55 square feet is the answer
Answer:
The probability of 1 or less children from that group to learn how to swim before 6 years of age is 0.072
Step-by-step explanation:
In this case we need to compute the probability of none of these 12 children learns to swim before 6 years of age. This is given by:
p(0) = (1 - 0.312)^(12) = 0.688^(12) = 0.01124
We now need to calculate the probability that one child learns to swim before 6 years of age.
p(1) = 12*0.312*(1 - 0.312)^(11) = 3.744*(0.688)^(11)
p(1) = 3.744*0.01634
p(1) = 0.0612
The probability of 1 or less children from that group to learn how to swim before 6 years of age is:
p = p(0) + p(1) = 0.01124 + 0.0612 = 0.07244
Answer:
$5865.6 per capita.
Step-by-step explanation:
That is $1465,2 billion divided by 249,793,675
= 1,465,200,000,000 / 249,793,675
= $5865.6 per capita.
There are infinite values of y possible. Take you pick.
1,2,3 and 4 are as good as any.
A.30 cm² B.70 cm² C.125 cm² D.150 cm²
If on Saturday, he biked at a rate that was 4 mph, her rate on saturday will be 11mph. Option B is correct.
The formula for calculating unit rate is expressed as:
Unit rate = Distance/Time
Unit rate = 60miles/4hrs
Unit rate = 15mi/hr
This shows that Andre rate on friday is 15mi/hr
If on Saturday, he biked at a rate that was 4 mph slower, her rate on saturday will be 15-4 = 11mph
