PLEASE HELP AND HURRY!
Kamila [148]

Answer:

ANSWER BELOW

Step-by-step explanation:

If the door is 9 x 2 ft (18 sq ft):

12 x 18 = 216 sq ft. (Front face including the door)

216 sq ft - 18 sq ft = 198 (Front face not including the roof or door)

For the roof, the formula is h b/2:

So if the height is 4 and the base is 18, the area of the roof is 36.

To find the total area, you must add the area of the front face and the roof (without the door).

198 + 36 = 234 sq ft

Have a wonderful day my friend!

OMG 25 POINTS!!!! HURRY AND GET SOME BRAINLIEST But MAKE SURE ANSWER IS RIGHT OR ILL REPORT YOU!!!!
Andrew [12]

The correct answer is the fourth option.

Given is a scatter graph with points marked on the graph. The x axis shows the dependent variable and y axis the independent variable

From the graph we see that there seems to be a linear relationship but not fully perfect.  Because so many points deviate from the line we can only say that there is a moderate association.

Whenever x increases y increases also the linear regression line of fit has a positive scope.

Hence there is a positive association between variable x and variable Y.

In how many ways can a student arrange 20 CDs in 4 CD player
stich3 [128]
We should find the number of possible ways the student can arrange 4CD from total 20 CDs. We should find the number of combinations.
Combination is a way of selecting r items (CDs) from a set (collection) of n items (CDs). The order of selection of the items does not matter in this situation. 
In our case: r=4 , n=20
The formula is: C=n!/(n-r)!*r!=20!/16!*4!=20*19*18*17*16!/16!*4!=20*19*18*17/4*3*2=116280/24=4845

y=2x^2-3, it can be prooved as 

-5/2= 2(-1/2)^2-3, so it is (-1/2,-5/2)
y=3x-1
5=3x2-1,so it is (2,5),
