Mathematics

Answer:

Step-by-step explanation:

Since the question is asking how long will it take him if he has to drive 240 miles and he drives 60 mph, this can be interpreted as division.

Now that we have converted the words into math, we are really solving 240 ÷ 60 or $\frac{240}{60}$ .

240 divided by 60 is the same as 24 divided by 6 because we can cancel the 0's.

Solving:

24 ÷ 6 = 4.

Thus, our answer is that it will take Charlie 4 hours to get to Dallas.

Trapezoid QRST has two right angles. A 5in. altitude can be drawn dividing QRST into a rectangle and an isosceles right triangle

iVinArrow [24]

The area of the trapezoid is 57.5 square inches.

If you draw out the description, you will see that your trapezoid can be divided into a rectangle that is 9 x 5 and an isosceles right triangle with a base of 5 and height of 5.

Just find the areas of both and add them together.

Rectangle:
5 x 9 = 45

Triangle:
0.5 x 5 x 5 = 12.5

45 + 12.5 = 57.5

In 2014, the percentage of the U.S population who was foreign-born was 13.1. Choose 60 U.S residents at random. Find the mean, v

makkiz [27]

Answer:

Hence Mean ,variance ,standard deviation who are foreign born are as

8, 6.83 ,2.613 respectively

Step-by-step explanation:

Given:

probability of success for foreign-born is 13.1 % p=0.131

probability of failure= q=1-0.131=0.869

n=60

To Find:

Mean ,variance and standard deviation

Solution:

We have here binomial distribution as probability for success (p)and number of trails are given (n).

So we know that formula for mean ,variance and standard deviation of binomial distribution are as follows ,

p=0.131

q=0.869

n=60

So Mean=μ= n*p

=60*0.131

=7.86

Hence mean will be 7.86 which approximately 8 persons.

Now for Variance=n*p*q

=60*0.131*0.869

=6.830

So variance will be 6.83

And for Standard deviation=Sqrt(variance)=Sqrt(n*p*q)

=Sqrt(6.83)

=2.613

Hence Mean ,variance ,standard deviation who are foreign born are as

8, 6.83 ,2.613 respectively.
