Answer:

C.) 17

Step-by-step explanation:

A die has  1,2,3,4,5,6

P(4) = number of 4's/ total numbers

       = 1/6

Multiply the number of roll's by the probability of getting a 4

100 *1/6 = 50/3 = 16 2/3

This is approximately 17

Answer: The slope of the line is m, which is 3.

Step-by-step explanation:

Don’t mind the two parts I scribbled out, I didn’t a few extra steps when I misread the instructions. Just look at the top left corner and the right side of how I solve for the slope.

Could someone help?<br> Thank you

Answer:

See Below

Step-by-step explanation:

Thankfully, all the parts you need are given.

First, find the surface of one triangle

A = 1/2bh

A = 1/2(15)(9)

A = 1/2(135)

A = 67.5

Multiply by 4 to get the sum of all the sides.

67.5(4) = 270

Now find the surface area of one square

A = bh

A = (15)(15)

A = 225

multiply by 5 to get all 5 sides

225(5) = 1125

Add sums together

1125 + 270 = 1395

Provide the reflected ordered pair for each of the given ordered pairs. Reflect the ordered pair ( − 4 , 5 ) (-4, 5) across the
levacccp [35]

Answer:

a) (4,5)

b) (0,-3)

Step-by-step explanation:

We have to perform the following reflection over given ordered pair.

a) Reflect the ordered pair (-4,5) across the y-axis

Reflection over y-axis:

r: (x,y)\rightarrow (-x,y)

Thus, (-4,5) will be reflected over y-axis as

r: (-4,5)\rightarrow (-(-4),5) = (4.5)

b) Reflect the ordered pair (0,3) across the y-axis

Reflection over x-axis:

r: (x,y)\rightarrow (x,-y)

Thus, (0,3) will be reflected over x-axis as

r: (0,3)\rightarrow (0,-(3)) = (0,-3)
