Answer:

Mean: 12.6

Median: 12

Mode: None

Step-by-step explanation:

To find the mode, add everything up.

12 + 9 + 17 +15 + 10 = 63. Then, divide by five.

63 ÷ 5 = 12.6

To find the median, put the numbers from least to greatest. Then, highlight the one in the middle.

9, 10, 12, 15, 17

To find the mode, look for the number that appears the most. Because each number appears once. So, put "none" in the box.

Have a wonderful day!

Answer:

18

Step-by-step explanation:

2^3 = 8

4^2 = 16

8+16=24

3/4 of 24 Is 18

Answer:

18

Step-by-step explanation:

[tex] \frac{3}{4} (8 + 16) \\ \frac{3}{4}(24) \\ 3 \times 6 \\ 18[/tex]

Step-by-step explanation:

|3x - 4| = 6

3x-4 = 6 or 3x-4 = -6

3x=6+4 3x=-6+4

3x=10 3x = -2

x= 10/3 x = -2/3

so, x1= 10/3 or x2 = -2/3

Step-by-step explanation:

Given data

Base edge a= 1.2

Hieght= 2.8

The expression for the volume of a pyramid is

V= a^2h/3

substitute

V= 1.2^2* 2.8/3

V= 1.44*2.8/3

V= 4.032/3

V= 1.34cubic units

Answer:

10

Step-by-step explanation:

6-3=3 then power of 2 which is 9 then plus 1

Answer:

C

Step-by-step explanation:

Substitute 6 for "x" in (x - 3)² + 1

(6 - 3)² + 1

We now evaluate the expression using PEMDAS

Parenthesis

Exponents

Multiplication and division ( from left to right )

Addition and subtraction ( from left to right )

Step 1: parenthesis

6 - 3 = 3

We would then have (3)² + 1

step 2: exponents

3²=9

we would then have 9 + 1 which = 10

Hence, the answer is C

Given:

In triangle ABC, AE is the angle bisector.

[tex]AB=4, BE=2, AC=x, CE=3[/tex]

To find:

The value of x.

Solution:

According to the angle bisector theorem, the angle bisector of a triangle divides the opposite side of the triangle into two parts. These two parts are proportional to the other two sides of the triangle.

Using the angle bisector theorem, we get

[tex]\dfrac{AB}{AC}=\dfrac{BE}{CE}[/tex]

[tex]\dfrac{4}{x}=\dfrac{2}{3}[/tex]

On cross multiplication, we get

[tex]4\times 3=2\times x[/tex]

[tex]12=2x[/tex]

Divide both sides by 2.

[tex]\dfrac{12}{2}=x[/tex]

[tex]6=x[/tex]

Therefore, the value of x is 6.

Answer:

C... 3

Step-by-step explanation:

Answer:

y = 2x +14

Step-by-step explanation:

We need to convert the given equation into slope intercept form ,

=> y - 6 = 2(x+4)

=> y -6= 2x + 8

=> y = 2x +8+6

=> y = 2x + 14

Answer:

x would equal 40

Question: Find the circumference of the circle to the nearest hundredth

d = 11cm

Answer:

34.54 cm

Step-by-step explanation:

Applying,

P = πd...................... Equation 1

Where P = Circumference of perimeter of the circle, d = diameter of the circle, π = pie

From the question

Given: d = 11 cm

Constant: π = 3.14

Substitute these values into equation 1

P = (3.14×11)

P = 34.54 cm

Answer:

b*h/2   120*90/2 10800/2=5400

Step-by-step explanation:

The area of the red triangle with sides A= 90 B=120 and C=150 would be equal to 5400.

The area of the triangle is defined as the product of half the base and the height of the triangle.

The area of the triangle = 1/2 x b x h

It is given that the length of the sides are as A= 90 B=120 C=150.

So, The area of the triangle = 1/2 x b x h

= b x h/2  

= 120 x 90/2

= 10800/2

= 5400

Answer:

3220 cm²

Step-by-step explanation:

Lets find the area of the two triangles

I am making a modification:

Both of the triangles are the same, so I wont divide by 2 using the area of triangle formula 1/2(b * h) because we end up multiply by 2

Area of triangles = 15 cm x 28 cm = 420 cm²

Area of front facing parallelogram = 24 cm x 4(10)cm = 100(10)cm = 1000 cm²

Area of back facing parallelogram = 17 cm x 40 cm = 680 cm²

Area of bottom parallelogram = 40 cm x 28 cm = 1120 cm²

Total Surface area = 420 cm² + 1000 cm² + 680 cm² + 1120 cm² = 1100 cm² + 2120 cm² = 3220 cm²

Answer:

t = 0.0475p

Step-by-step explanation:

If

p = paycheck ; t = amount paid in state income tax

Amount contributed towards retirement :

5% of p ; 0.05p

Amount left :

Paycheck - contribution

p - 0.05p = 0.95p

Amount paid in state income tax :

5% of amount left

5% of 0.95p

5/100 * 0.95p

0.05 * 0.95p

= 0.0475p

Hence, state income tax, t = 0.0475p

Answer:

y = 8 - 5x, y(-2) = 18, y(0) = 8, y(3) = -7

Step-by-step explanation:

y + 5x = 8

y = 8 - 5x

y(-2) = 8 - 5*(-2) = 8 + 10 = 18

y(0) = 8 - 5*(0) = 8 - 0 = 8

y(3) = 8 - 5*(3) = 8 - 15 = -7
