Answer:

C) (8,12)

Step-by-step explanation:

[tex]MP= (\frac{x_1+x_2}{2} )(\frac{y_1+y_2}{2} )\\MP= (\frac{5+11}{2} )(\frac{9+15}{2} )\\MP= (\frac{16}{2} )(\frac{24}{2} )\\MP= (8,12)[/tex]

The perimeter = the sum of the length of each side.

The shape with missing sides is a rectangle, and we know that rectangles have equal opposite sides.

The top of the rectangle = 3.5 and now we know all the values of each side.

3.5 + 3.5 + 2.4 + 2 + 2 = 13.4 cm.

The perimeter = 13.4cm

Answer:

x= 25.

Step-by-step explanation:

To isolate "x", I first moved all terms containing x to the left side of the equation: 0.32x-5=3 (0.4-0.08=0.32). Then moved all terms not containing x to the right side of the equation: 0.32x=8. Finally, I divided 8 by 0.32 which equals 25. Thus, x=25. I hope this helped!

Answer: 0

Step-by-step explanation:

To find the slope, you would need to use the formula [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex].

[tex]m=\frac{1-1}{-3-2} =\frac{0}{-5} =0[/tex]

The slope is 0, meaning the line is horizontal.

Answer:

I think it's 7

Step-by-step explanation:

I'm guessing I think

if x divided by 5 = 1760 , what is x ?

Set up an equation

[tex]\frac{x}{5}=1760[/tex]

Cross multiply

[tex]x=8800[/tex]

:)

Answer:

8,800

Step-by-step explanation:

5×1760=8800 if u divide that by 5

you get 1760

so its 8800

Answer:

A) 3²·3³

E) 3^4·3^1

Step-by-step explanation:

When multiplying numbers with exponents, keep the base the same and add the exponents.

So A and E would equal 3 to the fifth power.

Answer:

A & D

Step-by-step explanation:

3^5 = 243

The only other equations that also equal 243 are A & D.

You can also break the exponent up.

(Ex: The exponent is 5. You can split it by having 1 & 4 or 2 & 3)

(Ex continued: The number 3 must be the base number though.)

Step-by-step explanation:

The distance between two points can be found by using the formula

[tex]d = \sqrt{ ({x1 - x2})^{2} + ({y1 - y2})^{2} } \\ [/tex]

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(-3,3) and (-1,5)

The distance is

[tex]d = \sqrt{( { - 3 + 1})^{2} + ({3 - 5})^{2} } \\ = \sqrt{ ({ - 2})^{2} + ( { - 2})^{2} } \\ = \sqrt{4 + 4} \\ = \sqrt{8} \: \: \: \: \: \: \: \: \\ = 2 \sqrt{2} \: \: \: \: \: \: \\ = 2.82842[/tex]

We have the final answer as

Answer:

(3,15) and (-1.5, 1.5)

Step-by-step explanation:

If g(x) = 2x² - 3

The equation [tex]x^{3} - 3[/tex] has x values as 0, [tex]\sqrt{3}[/tex] and -[tex]\sqrt{3}[/tex].

We are given,

3 is subtracted from the cube of a number.

Let the number be x then we can write it as:

 [tex]x^{3}[/tex] - 3

We are to solve for x.

We can write the equation as:

[tex]x^{3}[/tex] - 3  = 0

x ( [tex]x^{2}[/tex]- 3 ) = 0

x = 0 and ( [tex]x^{2}[/tex] - 3 ) = 0

x = 0 and [tex]x^{2}[/tex] = 3

x = 0 and x = ±[tex]\sqrt{3}[/tex]

So we have,

x  = 0, [tex]\sqrt{3}[/tex] and -[tex]\sqrt{3}[/tex]

Thus we have x values as 0, [tex]\sqrt{3}[/tex] and -[tex]\sqrt{3}[/tex].

Answer: m=-9/10; d=13.45

Step-by-step explanation:

To find the slope, you would use the formula [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]. We plug in the given points and solve.

[tex]m=\frac{9-0}{0-10} =\frac{9}{-10} =-\frac{9}{10}[/tex]

Now, we know that slope is -9/10.

To find the distance between the points, we use the distance formula.

Distance formula: [tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

[tex]d=\sqrt{(0-10)^2+(9-0)^2}[/tex]             [parenthesis]

[tex]d=\sqrt{(-10)^2+(9)^2}[/tex]                       [exponent]

[tex]d=\sqrt{100+81}[/tex]                               [add]

[tex]d=\sqrt{181}[/tex]

[tex]d=13.45[/tex]

Now, we know the distance is approximately 13.45.

Answer:

96.89%

Step-by-step explanation:

Find the standard error:

s = σ/√n

s = 30 / √15

s = 7.75

Find the z-scores:

z = (x − μ) / s

z₁ = (225 − 240) / 7.75

z₁ = -1.94

z₂ = (260 − 240) / 7.75

z₂ = 2.58

Find the probability.

P(-1.94 < Z < 2.58) = P(Z<2.58) − P(Z<-1.94)

P(-1.94 < Z < 2.58) = 0.9951 − 0.0262

P(-1.94 < Z < 2.58) = 0.9689
