A furniture store routinely calls some customers to inquire about their buying experience in the showroom, the delivery and setup, and their overall satisfaction with

purchase. Today the calls will go to 2 homes randomly selected from last week's 5 customers. How many different groups of customers could the store call?

Answer:

x = 7

Step-by-step explanation:

A right angle is equal to 90 degrees

The sum of the angles, 55 and 5x, should equal 90

55 + 5x = 90

Isolate the variable

Subtract both sides by 55

55 - 55 + 5x = 90 - 55

5x = 35

Divide both sides by 5

5x ÷ 5 = 35 ÷ 5

x = 7

Answer:

) A (3, 5)            

(ii) B (-2, 7)          

(iii) C (-5, -8)      

(iv) D (9, -4)

Solution:

When rotated through 180° anticlockwise or clockwise about the origin, the new position of the above points is.

(i) The new position of the point A (3, 5) will be A' (-3, -5)

Answer:

The water droplet is in the air for two seconds.

Step-by-step explanation:

You can solve this by finding the times at which its height is zero.  The lesser of the two values will be upon launch, and the greater upon landing:

y = -16x² + 32x

Let y = 0

-16x² + 32x = 0

factor -16 out:

x² - 2x = 0

complete the square:

x² - 2x + 1 = 1

and solve for x

(x - 1)² = 1

x - 1 = ±1

x = 1 ± 1

x = 0, 2

So the water is at a height of zero at zero seconds and two seconds.  It's thus in the air for two seconds.

Answer:

h=52

Step-by-step explanation: You subtract 36 from both sides and it cancels on the right but on the left you do regular subtraction and you get that h equals 52

Answer:

h = 52

Step-by-step explanation:

h + 36 = 88

subtract 36 from both sides

h = 52

Answer:

Step-by-step explanation:

1) Find the Mean of all the numbers.

3+4+5+7+10+12+15=56

56/7=8 mean is 8

Now We Calculate Standard Deviation:

S=[tex]\sqrt{(3-8)^2+(4-8)^2+(5-8)^2+(7-8)^2+(10-8)^2+(12-8)^2+(15-8)^2}[/tex]

You take each number from the problem i.e 3,4,5...

and then you subtract the mean from it and then square it.

S=[tex]\sqrt{(-5)^2+(-4)^2+(-3)^2+(-1)^2+(2)^2+(4)^2+(7)^2}[/tex]

S=[tex]\sqrt{25+16+9+1+4+16+49}[/tex]

S=[tex]\sqrt{120}[/tex]

S=[tex]\sqrt{120}/7[/tex]

7 is the amount of data units given in the problem.

120/7=17.1428571429

[tex]\sqrt{17.1428571429}[/tex] =4.1403933560541

there isn't much to learn here this is just something that you come to know off the top of your head

Answer:

A

Step-by-step explanation:

You should know the area of a circle, A = πr².

So, all you need to find is the area of half a circle, or A = [tex]\frac{1}{2}[/tex] πr²

We see that the radius is half of the diameter or r = 6 in.

A = [tex]\frac{1}{2}[/tex] (3.14)(6)²

A = 56.52 in²

Answer:

124984638540

Step-by-step explanation:

just use a calculator

Answer:

Suppose that you have a random point (x, y), and now you do a dilation from the origin with a scale factor of k.

Then the new coordinates of the point are:

(k*x, k*y)

Now, in this question, we have a dilation of scale factor k = 1/2.

Then if we start with the point (x, y), after the dilation we will have the point (x/2, y/2)

Now you can notice that instead of this, in the table we have (2*x, 2*y)

So this is the error, the transformation is not correctly calculated.

Answer: x=2, x=-1

Step-by-step explanation:

First you have to make it so that everything is on the same side so 2x^2+7x-4

Then you do cross multiply 2x=4 and x=0. I don't know really how to explain it but the answer is x=2 x=-1

Answer:

[tex]\displaystyle \frac{x + 2}{x + 9}, \ x \neq -9, \ 12[/tex]

Pre-Algebra

Order of Operations: BPEMDAS

Algebra II

Step-by-step explanation:

Step 1: Define

[tex]\displaystyle \frac{x^2 - 10x - 24}{x^2 - 3x - 108}[/tex]

Step 2: Simplify

We know that x cannot equal -9 because we would get a divide by 0 (undefined) error. We also know that x cannot equal 12 because it was canceled out when simplifying.
