Using proportions, it is found that it will take them 0.00248548 minutes to do one loop.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, according to their speed, in 60 minutes, they drive 300 miles. In how many minutes will they drive 20 m = 0,0124274 miles?
The <em>rule of three</em> is:
60 min - 300 miles
x min - 0.0124274 miles
Applying cross multiplication:
It will take them 0.00248548 minutes to do one loop.

Answer:
a) 151lb.
b) 6.25 lb
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a random variable X, with mean 
and standard deviation 
, a large sample size can be approximated to a normal distribution with mean and standard deviation 
.
In this problem, we have that:
So
a) The expected value of the sample mean of the weights is 151 lb.
(b) What is the standard deviation of the sampling distribution of the sample mean weight?
This is 
For the coin it would be 50%
for the cube it has six sides so it would be 1/6
2 is a multiple of 4, so anything that's a multiple of 4 will automatically be a multiple of 2
so 3 x 4 = 12
so multiples of 12 that are between 67 and 113 are...?
12 x 6 = 72
12 x 7 = 84
12 x 8 = 96
12 x 9 = 108 <span> 72 or 84 or96 or 108
all are divisible by 2,3 and 4
all fall between 67 and 112</span>
Answer:
x = 31
Step-by-step explanation:
The 88-deg angle is an exterior angle of the triangle.
The 57-deg angle and x are its remote interior angles.
<em>Theorem:</em>
<em>The measure of an exterior angle of a triangle is equal to the sum of the measures of its remote interior angles.</em>
x + 57 = 88
x = 31
