D) 4.5 Standard Deviations Above the Mean

All you have to do is add .2 to 6.6 until you reach 7.5

6.8
7.0
7.2
7.4

 Then you only need half of .2 to reach 7.5, so it's 4.5 standard deviations above the mean

The Saxena family plans to install a light to illuminate part of their rectangular yard. Nikki and Dylan each proposed a differe

F) Dylan's proposed placement will light exactly half of the yard.

<h3>What is Area of Triangle?</h3>

The area of a triangle is defined as the total space occupied by the three sides of a triangle in a 2-dimensional plane. The basic formula for the area of a triangle is equal to half the product of its base and height, i.e.,  A = 1/2 × b × h.

The area of a triangle =  (base x height) / 2

and,

both lights illuminate the same base and height = (60 x 38) / 2

                                                                                 =  1,140 sq ft

Both Dylan's and Nikki's proposed placement will lit exactly half of the yard.

The yard's total area = 60 x 38 = 2,280 sq ft,

which is twice the area lit by the lights.

Thus, The correct situation for the given condition are as follows:

C) Both proposed placements will light the same sized area.

F) Dylan's proposed placement will light exactly half of the yard.

A standard die is rolled three times. What is the probability of rolling a number less than 5 on all three rolls?
katrin [286]

Answer:

5/6

Step-by-step explanation:

This is because when you roll three times, there are 18 possible numbers (six numbers three times). If you want to get less than five each time, that is 5 number x 3 rolls = 15 numbers.

So...You get 15/18 which simplifies to 5/6

What is Point-Slope Form? What is Slope Intercept Form? What is the Slope Formula?
kipiarov [429]

Answer:

For the first part

1.) Negative

2.)zero

3.) undefined

4.) positive

The point slope formula is y-y1=m(x-x1). It is best to use if you already know the slope and one other point on the line. It is used to find another point on the line.

The slope-intercept form is used to show a line. To use this form, you need to know the slope and the y-intercept.

The slope formula is y=mx+b. M is the slope while b is the y-intercept.

8(2x – 10) = 28<br> What is the steps to complete?
MrRa [10]

Answer:

6.75

Step-by-step explanation:

first let's simplify whatever is inside the parantheses

8(2x-10)=28

8*2(x-5)=28

16(x-5)=28

now we divide both sides by 16 to get rid 16

x-5 = 28/16

now move -5 to the right side

x = 28/16 + 5

x = 28/16 + 80/16 = 108/16 = 6.75
