Answer:

there will be about 115 customer

Step-by-step explanation:

the y intercept is 2.5

(0,2.5)  (100 ,35)

the slope is (y2-y1)/(x2-x1)

m = (35-2.5)/(100-0)

m= (32.5)/100

m = .325

y = mx+b

y = .325x+2.5

let y =40  for 40 cars in all the spot

40 = .325 x + 2.5

subtract 2.5

37.5 =.325 x

divide by .325

37.5 /.325 = x

115.4 = x

there will be about 115 customer

Answer:

x > 1/6.

Step-by-step explanation:

–2(8x – 4) < 2x + 5

-16x + 8 < 2x + 5

-18x < -3

x > 1/6.

The solution to the inequality expression is x > 1/6

Given the inequality expression

–2(8x – 4) < 2x + 5

Expand the parenthesis

-16x + 8 < 2x + 5

Subtract 5 from both sides

-16x + 8 - 5 < 2x + 5 - 5

-16x + 3 < 2x

-16x - 2x < -3

-18x < -3

Divide both sides by -18

-18x/-18 > -3/-18

x > 1/6

Hence the solution to the inequality expression is x > 1/6

Answer:

no because complementary angles equal 90 degrees and supplementary angles equal 180 degrees

Answer:

No they cannot.

Step-by-step explanation:

They cannot because if they were then what would be the point of complementary and supplementary? Why would be need to call them different angles if they are the same?

Hope this helps!

Answer:

20.8

Step-by-step explanation:

tan = opposite/ adjacent

opposite = tan * adjacent

opposite = 1,482561 * 14 = 20,755854

Answer:

20.8 =x

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

tan theta = opp / adj

tan 56 = x/ 14

14 tan 56 =x

20.75585356 =x

To the nearest tenth

20.8 =x

Answer:Extract the formula for the height of a rectangular-based pyramid using your knowledge of algebra. H = V / (L x W) / 3. For instance, V = 60 cubic cm, L = 4 cm and W = 6 cm.

Answer:

x = 12

Step-by-step explanation:

24 = 3x - 12 (opposite sides of a parallelogram are equal)

24 + 12 = 3x

36 = 3x

36/3 = x

12 = x

Answer:

x=13

Step-by-step explanation:

The parallel sides on a parallelogram are equal, therefore you must find a number that would satisfy the requirement for equality in the sides' length

So lets get started by finding out what number would be 24 after 12 has been subtracted from it.

24+12=36

Now we need to find out how to get 36 from 3x

36/3=13

13.

x is 13.

Now lets check that our answer is right

13x3=36

so far so good.

36-12=24

That checks out.

24=24.

Answer:

Step-by-step explanation:

Expression on the board :

[tex]12.2x + 50.6 y + 3(1.4x - 2.6y)\\\\= 12.2x + 50.6y + 4.2x - 7.8y\\\\= 16.4x + 42.8y[/tex]

Expression by the student :

Expression 1 :

[tex]4 ( 4.1x + 10.7 y ) \\\\= ( 4 \times 4.1x ) + ( 4 \times 10.7 y)\\\\= 16.4x + 42.8y\\\\[/tex]

The expression 1 is equivalent to the expression on the board. Because the coefficients of x and y are same on both.

Expression 2 :

[tex]2 ( 6.1x + 25.3 y + 2.1x -3.9y)\\\\= 2 ( 8.2x + 21.4y)\\\\=( 2 \times 8.2x ) + (2 \times 21.4y)\\\\= 16.4x + 42.8y[/tex]

The expression 2 is also equivalent to the expression on the board. Because the coefficients of x and y are the same.

Answer:

The answer is C because 14 - 3 = 11 x 2 = 22

Answer:

C

Step-by-step explanation:

Knowing x=14, we will substitute 14 when we see x.

In the equation 2(x-3) =22, when we substitute 14 for x we get 2(14-3)=22

Following PEMDAS, we do what's in the parenthesis first. 14 minus 3 gives us 11 and multiplying that by 2 will give us 22.

22=22 is true and therefore, C is your correct option.

Answer:

(3, -1), 7

Step-by-step explanation:

To find the center of this circle:  compare the given equation

(x - 3)^2 + (y + 1)^2 = 7^2   to the standard equation of a circle with center at (h, k):

(x - h)^2 + (y -k)^2 = r^2

From this comparison we see that the center is at

h = 3 and k = -1, and also that r must be 7:    (3, -1), 7

Answer:

Step-by-step explanation:

7x = x² - 8

=> x² - 7x - 8 = 0

use quadratic formula:

a = 1, b = -7, c = -8

x = [tex]\frac{-(1)±\sqrt{(-7)^{2} - 4(1)(-8) } }{2(1)}[/tex] (pls ignore the "A" I don't know why it's showing up)

=> x = [tex]\frac{-1±\sqrt{49 + 32} }{2}[/tex]

=> x = [tex]\frac{-1±9 }{2}[/tex]

=> x = [tex]\frac{-1 +9}{2}[/tex] = 4 or [tex]\frac{-1-9}{2}[/tex] = -5 (the answer is only 4 since it's asking for the positive solution)

IQR is shorthand for interquartile range

=========================================================

Explanation:

The original list is {84,75,90,87,99,91,85,88,76,92,94}

It sorts to {75,76,84,85,87,88,90,91,92,94,99}

Pick out the middle most value, which is 88 in slot 6. A quick way to get here is to see that there are n = 11 values in this set. So n/2 = 11/2 = 5.5 which rounds to 6, and that tells us the slot number where the median is held. If n is an even number, then you'll need to use the midpoint formula for the two middle-most items.

After we determine the median is 88, we split the sorted data set as follows:

L = {75,76,84,85,87}

U = {90,91,92,94,99}

Everything in set L is below the median. L for lower.

Everything in set U is above the median. U for upper.

Sets L and U have 5 items each. Note that 5+1+5 = 11 = n.

-------------

The median of set L is 84, so Q1 = 84

The median of set U is 92, so Q3 = 92

Q1 and Q3 are the first and third quartiles respectively. Subtracting them gets us the IQR (interquartile range)

IQR = Q3 - Q1

IQR = 92 - 84

IQR = 8

The IQR helps give us a sense how spread out the data set is. It's similar to the range, which is found by range = max - min. The larger the (interquartile)range, the more spread out the data set will be.
