Answer:

A frequency table and a line plot show which value occurs most often. this is done by labeling every value. The person can clearly see the organized layedout numbers in a frequency table or line plot.

Answer:

The answer to a subtraction problem - Difference.

The answer to a addition problem - Sum.

The answer to a multiplication problem - Product.

2 + 3 + 4 = 2 + 4 + 3 - Commutative Property of Addition.

2 x 3 x 4 = 4 x 2 x 3 - Commutative Property of Multiplication.

Any number that can be written as a fraction - Rational number.

i hope that helped at all.

a rectangle has a length of 8ft and a width of 6ft. if its length and width increase by 50% each, what is the area of the new re

Nadya [2.5K]

Answer:

108 ft²

Step-by-step explanation:

Increasing by 50% means multiplying the original quantities by 1.5, that is

100% + 50% = 150% = 1.5 ( 100% is the original dimensions ), thus

new length = 1.5 × 8 ft = 12 ft

new width = 1.5 × 6 ft = 9 ft

Thus

Area = length × width = 12 × 9 = 108 ft²

The Environmental Protection Agency (EPA) publishes fuel economy values that are known to be good estimates of the fuel economy

r-ruslan [8.4K]

Answer:

The 90% confidence interval for the mean combined fuel economy for Ford Explorers is between 22.95 and 23.63 mpg.

Step-by-step explanation:

We have the standard deviation for the sample, which means that the t-distribution is used to solve this question.

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So

df = 16 - 1 = 15

90% confidence interval

Now, we have to find a value of T, which is found looking at the t table, with 15 degrees of freedom(y-axis) and a confidence level of $1 - \frac{1 - 0.9}{2} = 0.95$ . So we have T = 1.7531

The margin of error is:

$M = T\frac{s}{\sqrt{n}} = 1.7531\frac{0.78}{\sqrt{16}} = 0.34$

In which s is the standard deviation of the sample and n is the size of the sample.

The lower end of the interval is the sample mean subtracted by M. So it is 23.29 - 0.34 = 22.95 mpg

The upper end of the interval is the sample mean added to M. So it is 23.29 + 0.34 = 23.63 mpg

The 90% confidence interval for the mean combined fuel economy for Ford Explorers is between 22.95 and 23.63 mpg.
