Answer:

13. 3

Step-by-step explanation:

Given Points:

(x1= 4, y1 = 11), (x2= - 9, y2 = 8)

Distance Formula:

d² = (x2 -x1)² + (y2 -y1)²

Substitute and Calculate:

d² = ( -9 -4)² + ( 8 -11)²

d² = (-13)² + (-3)²

d = √(169+9)

d = √178

d = 13.34166406 round to the nearest tenth

d = 13. 3

If each kite measures 6 inches across and 12 inches long. The square inches of the wall will be:  864 square inches.

Diagonals= d1 and d2

First step

Area =(1/2)×(d1×d2)

Area=(1/2)×(6×12)

Area =36 in²

Second step

1 feet = 12 inches

12 feet =  12×12

12 feet = 144 in

Third step

Number of square inches=(144/6)×36

Number of square inches=24×36

Number of square inches= 864 square inches

Therefore the square inches of the wall will be: 864 square inches.

60 percent of $69.80 = $41.88

Answer:

27.92$

Convert 60% into its decimal form.(0.6)

When finding the part of the whole number and percent, you must multiply.

[tex]0.6 * 69.80 = 41.88[/tex]

Now, to find the actual price, subtract 60% of 69.8(41.88) by 69.8

[tex]69.8 - 41.88 = 27.92\[/tex]

Therefore, the item is on sale for 27.92$

Answer:

dimensions 20cm x80cm

Step-by-step explanation:

length is 4W of 1W,

LxW=area of 1600

4W x 1W = 1600cm2

divide both by 4 to isolate W

W=400cm2

square root of 400=20

replace W with 20 into equation 4Wx1W

4x20=80

1x20=20

80 is 4x the width of 20

-11x - 72 = 84 + x

combine like terms on opposite side of =

(-11x )+ (-1x) = (84) + (72)

-12x = 156

divide both sides by -12 to isolate x

-12/-12 = 156/-12

x = -13

insert (-13)  for x

(-11 * -13) -72 = 84 + (-13)

The cost of an order of 1 hamburger and 2 orders of fries cost which Nathaniel and Liam bought is $6.5.

A system of equation is the set of equation in which the finite set of equation is present for which the common solution is sought.

Let the cost of 1 hamburger is x dollar and 2 orders of fries is y dollars. Nathaniel bought 3 hamburgers and 2 orders of fries for $12.50. Thus,

[tex]3x+2y=12.5[/tex]

Solve this equation as,

[tex]2y=12.5-3x\\y=\dfrac{12.5-3x}{2}[/tex]                        .....1

Liam bought 2 hamburgers and 4 orders of fries for $13. Thus,

[tex]2x+4y=13[/tex]

Put the value of y in this equation and solve it further,

[tex]2x+4(\dfrac{12.5-3x}{2})=13\\2x+25-6x=13\\-4x=13-25\\-4x=12\\x=\dfrac{12}{4}\\x=3[/tex]

Put this value of x in equation 1,

[tex]y=\dfrac{12.5-3\times3}{2}\\y=\dfrac{3.5}{2}\\y=1.75[/tex]

The cost of an order of 1 hamburger and 2 orders of fries is,

[tex]C=3\times 1+2\times1.75\\C=3+3.5\\C=6.5[/tex]

Thus, the cost of an order of 1 hamburger and 2 orders of fries cost which Nathaniel and Liam bought is $6.5.

[tex]\qquad \textit{perfect square trinomial} \\\\ (a\pm b)^2\implies a^2\pm \stackrel{\stackrel{\text{\small 2}\cdot \sqrt{\textit{\small a}^2}\cdot \sqrt{\textit{\small b}^2}}{\downarrow }}{2ab} + b^2[/tex]

the idea behind the completion of the square is simply using a perfect square trinomial,  hmmm usually we do that by using our very good friend Mr Zero, 0.

if we look at the 2nd step, we have a group as x² - x, hmmm so we need a third element, which will be squared.

keeping in mind that the middle term of the perfect square trinomial is simply the product of the roots of "a" and "b",  so in this case the middle term is "-x", and the 1st term is x², so we can say that

[tex]\stackrel{middle~term}{2(\sqrt{x^2})(\sqrt{b^2})~}~ = ~~\stackrel{middle~term}{-x}\implies 2xb~~ = ~~~~ = ~~-x \\\\\\ b=\cfrac{-x}{2x} \implies b=-\cfrac{1}{2}[/tex]

so that means that our missing third term for a perfect square trinomial is simply 1/2, now we'll go to our good friend Mr Zero, if we add (1/2)², we have to also subtract (1/2)², because all we're really doing is borrowing from Zero, so we'll be including then +(1/2)² and -(1/2)², keeping in mind that 1/4 - 1/4 = 0, so let's do that.

[tex]-3~~ = ~~-2\left[ x^2-x+\left( \cfrac{1}{2} \right)^2 ~~ - ~~\left( \cfrac{1}{2} \right)^2\right]\implies -3=-2\left(x^2-x+\cfrac{1}{4}-\cfrac{1}{4} \right) \\\\\\ -3=-2\left(x^2-x+\cfrac{1}{4} \right)+(-2)-\cfrac{1}{4}\implies -3=-2\left(x^2-x+\cfrac{1}{4} \right)+\cfrac{1}{2} \\\\\\ -3-\cfrac{1}{2}=-2\left(x^2-x+\cfrac{1}{4} \right)\implies -\cfrac{7}{2}=-2\left(x-\cfrac{1}{2} \right)^2\implies \cfrac{7}{4}=\left(x-\cfrac{1}{2} \right)^2[/tex]

[tex]~\dotfill\\\\ \pm\sqrt{\cfrac{7}{4}}=x-\cfrac{1}{2}\implies \cfrac{\pm\sqrt{7}}{2}=x-\cfrac{1}{2}\implies \cfrac{\pm\sqrt{7}}{2}+\cfrac{1}{2}=x \implies \cfrac{\pm\sqrt{7}+1}{2}=x[/tex]

Answer Question 1: Mean literal number 85.55556 Not sure if there allowing you to round to the nearest tenth of digit

Median 90

Mode 95

Range 35

Question 2: Median is the best way because it gives you the overall average of a set of numbers.

Question 3: The mean would change because if you are adding new numbers you have to recount the mean meaning there is now a new average.

Answer:

The mean is 80.875 or 81 rounded

Step-by-step explanation:

To find the mean of any set of numbers, you need to get the values added up together and the #values (how much numbers there are).

Formula setup: amountaddedup/#numbers

✔ When we plug in the values in the formula, you will get 80.875.

The mean of the given data is 80.75.

Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.

The given data is 95, 45, 37,82 ,90,100, 91 ,78 , 67 ,84 ,85 ,85 , 82 , 91 , 93 , 92,76,  84, 100, 59 , 92,  77 , 68 and 88

Mean = Sum of the observations/ Total number of observation.

Sum of the observations = 95+ 45+37+82+90+100+91+78+67+84+85+85 +82 +91+93+92+76+84+100+59+92+77+68+88

=1941

Total number of observation= 24

Mean = 1941/24

=80.875

Hence, the mean of the given data is 80.75.

The function is not treated as linear because whenever we throw the thing in the air it traces the path of the parabola which is quadratic. Then the quadratic equation is y = -1.25x² + 7.35x + 3.2.

It is a polynomial that is equal to zero. Polynomial of variable power 2, 1, and 0 terms are there. Any equation having one term in which the power of the variable is a maximum of 2 then it is called a quadratic equation.

The following scatter plot represents the height of a basketball in seconds during a free throw shot.

(a) A student chose to model the data with the function, y = 0.9286x + 9.0571 . Then the function is not treated as linear because whenever we throw the thing in the air it traces the path of the parabola which is quadratic.

(b) Write a function

We know that the quadratic equation is given as ax² + bx + c = y

This will pass through the points (1, 9.3), (2, 12.9), and (3, 14). Then we have

[tex]\rm a + b + c = 9.3 \ \ \ \ \ \ \ ...1\\\\4a + 2b + c = 12.9 \ \ \ ...2\\\\9a + 3b + c = 14 \ \ \ \ \ \ ...3[/tex]

On solving the equations 1, 2, and 3. Then we have

a = -1.25, b = 7.35, and c = 3.2
