Answer:

The type of graph you can use to compare the number of books at each price is Histogram and a box and whisker plot.

Step-by-step explanation:

A histogram is another good example for providing a good general view of the data. I choose histogram instead of a bar chart because the data is not categorical, but continuous and quantitative.

The second option of my choice is A box and whisker pot, because it is useful for comparing these 2 sets of data, spread and outliers, also can easily compare the quartile values and get a overall view of comparison for a sets of data.

Answer:

16y-4x

Step-by-step explanation:

first distribute the negative to the numbers in parentheses

13y-5x+3y+x

then combine like terms

13y+3y=16y

-5x+x=-4x

16y-4x

A group of physical education majors was discussing the heights of female runners and whether female runners tended to be tall,

Anna11 [10]

Answer:

The 90% confidence interval for the mean µ of the population of female runners.

( 65.0328 , 66.5672)

Step-by-step explanation:

Step(i)

Given A sample of 12 runners showed a sample mean height of 65.80 inches and a sample standard deviation of 1.95 inches.

Given sample size is n = 12 <30 so small sample

Given sample mean (x⁻) = 65.80 inches

sample standard deviation (S) = 1.95 inches.

Step(ii)

Assume the population is approximately normal.

The 90% confidence interval for the mean µ of the population of female runners.

$(x^{-} - t_{\alpha } \frac{S}{\sqrt{n} } ,x^{-} +t_{\alpha } \frac{S}{\sqrt{n} } )$

substitute all above interval

$(65.80 - t_{\alpha } \frac{1.95}{\sqrt{12} } ,65.80 +t_{\alpha } \frac{1.95}{\sqrt{12} } )$

The degrees of freedom γ=n-1 = 12-1=11

From t- table = 1.363 at 90 % 0r 0.10 level of significance

$(65.80 -1.363 \frac{1.95}{\sqrt{12} } ,65.80 +1.363 \frac{1.95}{\sqrt{12} } )$

on calculation , we get

(65.80 -0.7672 ,65.80 + 0.7672)

( 65.0328 , 66.5672)

3y- 12x = 18 2y-8x= 12

arlik [135]

Answer:

x=0

y=6

Step-by-step explanation:

3y- 12x = 18

2y-8x= 12

rearrange the equation

2y-8x=12

add 8x to both sides

2y=8x+12

divide both sides by 2

y=4x+6

now substitute it into 3y-12x=18

3(4x+6)-12x=18

simplify

12x+18-12x=18

simplify

18=18

x=0

substitute to find y

2y-8(0)=12

2y=12

y=6

Recheck:

3(6)-12(0)=18

18=18

2(6)-8(0)=12

12=12

What is the y-intercept of the graph of the line whose equation is y=3/4x+1

Tanzania [10]

Answer:

The correct answer is "1".

Step-by-step explanation:

You need only set x to zero, and solve for y:

$y = \frac{3}{4} x + 1\\y = \frac{3}{4}0 + 1\\y = 1$
