Answer:

71.5

Step-by-step explanation:

To find the median score you have to find the number in the middle.

First put them in the ascending order: 69,70,71,72,73,74

Now take away one from each side:

70,71,72,73

You are left with these numbers: 71,72

Now to find the median add them: 71 + 72 = 143

Then divide your answer always by 2:

143 ÷ 2 = 71.5

Here is another example: 3,1,2

Ascending order: 1,2,3

Now take away one from each side and you will be left with 2

Hope this helps!

Answer:

The coordinates of the midpoint are;

(-6.5, -3)

Step-by-step explanation:

Here, we want to get the midpoint of the line segment

To get this, we use the midpoint formula;

(x,y) = (x1 + x2)/2, (y1 + y2)/2

Thus;

(x,y) = (8 - 21)/2, (-10 + 4)/2

(x,y) = -13/2 , -6/2

(x,y) = (-6.5 , -3)

Answer:

Answer:

x < -0

Step-by-step explanation:

Note that y is increasing on the interval (-3, 0).  We could generalize this to:

x < -0 (Answer C)

Answer:

Not a triangle

Step-by-step explanation:

In order for a shape to qualify as a triangle, the interior angles must add up to 180°

These angles only add up to 56°, therefore it is not a triangle.

Answer:

obtuse

Step-by-step explanation:

You have an isosceles triangle. 2 of the sides are equal in length. Since, the third side is longer than than the other 2, it will form an obtuse angle. If the third side was shorter, you would have all acute angles.

Solving |-7-1| we get 8

Step-by-step explanation:

We need to solve |-7-1|

Absolute value is non-negative number even the number has negative sign.

So, |a| = a or |-a|=a

So, solving |-7-1|

=|-8|

=8

So, Solving |-7-1| we get 8

Answer:

$5

Step-by-step explanation:

We are given that  profit equation

[tex]P(x)=-2x^2+20x+0[/tex]

Where x=Charges per pair of mittens

We have to find the charge per pair of mittens to make her max profit.

Differentiate equation w.r.t x

[tex]\frac{dP}{dx}=-4x+20[/tex]

[tex]\frac{dP}{dx}=0[/tex]

[tex]-4x+20=0[/tex]

[tex]4x=20[/tex]

[tex]x=5[/tex]

Again differentiate w.r.t x

[tex]\frac{d^2P}{dx^2}=-4<0[/tex]

Hence, the profit is maximum at x=5

Lily should charge $5 per pair of mittens to make her max profit .

Answer:

[tex]\frac{8}{25}[/tex] which is 0.32 in decimal form

Given:

Perimeter of a square = [tex]32x-12.8[/tex]

To find:

The side length of the square.

Solution:

We know that, the perimeter of the square is 4 times of its side length.

[tex]P=4a[/tex]

Where, a is the side length.

Perimeter of a square = [tex]32x-12.8[/tex]

Now,

[tex]4a=32x-12.8[/tex]

Divide both sides by 4.

[tex]a=\dfrac{32x-12.8}{4}[/tex]

[tex]a=\dfrac{32x}{4}-\dfrac{12.8}{4}[/tex]

[tex]a=8x-3.2[/tex]

Therefore, the side length of the square is [tex]8x-3.2[/tex] units.

Answer:

Answer:

The sixth term is -3,072

Step-by-step explanation:

Here, we want to get the 6th term

From the question, the first term is -12

the common ratio would be -12/3 = -4

So the sixth term will be;

ar^5

= 3 * (-4)^5 = -3072

Answer:

Step-by-step explanation:

2x-3 > 2x-5/2

⇒2x-3/1=2x-5/2

⇒(2x-3)×2=(2x-5)×1

4x-6=2x-5

⇒2x-1>0

⇒2x>1

⇒x>1/2

Answer:

[tex]2x - 3 > \frac{2x - 5}{2} \\ 2(2x - 3) > 2x - 5 \\ 4x - 6 > 2x - 5 \\ 4x - 2x > 6 - 5 \\ 2x >1 \\ \boxed{x > \frac{1}{2} }[/tex]

Answer:

v>2/3

Step-by-step explanation:

2(4−1)<2(3v+1)

Step 1: Simplify both sides of the inequality.

6<6v+2

Step 2: Flip the equation.

6v+2>6

Step 3: Subtract 2 from both sides.

6v+2−2>6−2

6v>4

Step 4: Divide both sides by 6.

6v/6>4/6

v>2/3

Answer:

v>2/3

Step-by-step explanation:

Switch sides: 2(3v+1)>2(4-1)

Ope the brackets and multiply

6v+2)>2*3

Subtract 2 on both sides

6v>6-2

6v>4

v>4/6

v>2/3

Answer:

Step-by-step explanation:

[tex]\huge\mathrm{\underline{\underline{Answer}}}[/tex]

Ans:-The sum is ₹30,000

[tex]\begin{cases} (x_1,y_1)=(-3,4) \\ (x_2,y_2)=(2,8) \end{cases} \\ m = \frac{y_2 - y_1}{x_2 - x_1} [/tex]

[tex]m = \frac{8 - 4}{2 - ( - 3)} \\ m = \frac{4}{2 + 3} \Longrightarrow \frac{4}{5} [/tex]

We have got the value of slope. Substitute in the slope-intercept form.

[tex]y = mx + b \\ \sf{m = slope}\\ \sf{b = y - intercept}[/tex]

Substitute and Rewrite the equation.

[tex]y = \frac{4}{5} x + b[/tex]

I will substitute (2,8) in.

[tex]y = \frac{4}{5} x + b \Longrightarrow \sf \small{Substitute \: \: the \: \: coordinate \: \: points \: \: in \: \: the \: \: equation}[/tex]

[tex]8 = \frac{4}{5} (2) + b \\ 8 = \frac{8}{5} + b \\ 40 = 8 + 5b \\ 40 - 8 = 5b \\ 32 = 5b \\ \frac{32}{5} = b[/tex]

Rewrite the equation by substituting the value of b.

[tex]y = \frac{4}{5} x + \frac{32}{5} [/tex]

[tex] \large \boxed{y = \frac{4}{5} x + \frac{32}{5} }[/tex]
