Bezzdna [24]

Answer:

The median is the average of all the numbers so you would first add all the numbers together which is 16+12+13+14+19+13+17+13=117

then you divide 117/8=14.6

Then your median is the middle number of all your numbers in numerical order

12, 13, 13, 13, 14, 16, 17, 19

which is 13 and 14, and between those two numbers is 13.5

Marina CMI [18]

Answer:

The option J 36.7 inches best represents the length of hypotenuse.

Step-by-step explanation:

The question is incomplete, so below is the complete question:

A triangle has one leg of 32 inches and one leg of 18 inches. For the triangle to be a right triangle, which best represents the length of the hypotenuse?

F 34.2 inches G 36 inches H 41.8 inches J 36.7 inches.

Now, to find the hypotenuse.

Leg 1 = 32 inches.

Leg 2 = 18 inches.

Now, to get the hypotenuse we use pythagoras theorem:

$(Leg1)^2+(Leg2)^2=(Hypotenuse)^2$

$(32)^2+(18)^2=(Hypotenuse)^2$

$1024+324=(Hypotenuse)^2$

$1348=(Hypotenuse)^2$

Using square root on both sides we get:

$36.7=Hypotenuse$

$Hypotenuse=36.7\ inches.$

Therefore, the option J 36.7 inches best represents the length of hypotenuse.

What is -3(2n+1)+7=-5

SCORPION-xisa [38]

-3(2n+1)+7=-5
Multiply the number outside of the parenthesis with the numbers inside the parenthesis
-6n-3+7= -5
Subtract 7 from both sides
-6n-3=-12
Add 3 to both sides
-6n=-9
Divide -6 on both sides
