The speeds (in miles per hour) of motorists ticketed during one day on a five-mile stretch of highway are

listed below.

80, 70, 89, 85, 85, 75, 72, 73, 80, 83, 86, 88, 88, 70, 89, 74, 75, 84, 73, 71



The mean speed is 79.5 mph with a standard deviation of 6.8 m.

Answer:

Impossible not likely to happen

Answer:

(0.2)(38)

Step-by-step explanation:

To find a percent, you multiply the number (cost) by the decimal of the percent

20% as a decimal is .2

Answer:

0.2 48

Step-by-step explanation:

20% change into decimal form is 0.2 you move decimal two places left.

Answer:

Your Balance Would Be $1400.

How I Found The Answer:

$1000 Is 100%

$1000 ÷ 100 = $10

$10 Is 1%

$10 × 8 = $80

$80 × 5 = $400

$1000 + $400 = $1400

Your Balance Would Be $1400.

Answer:

The awnser would be 9 because its under the sum of 10

Answer:

9 (see below)

Step-by-step explanation:

So, for a triangle, if you add any two sides, it will always be greater than the third side.

So if a triangle has sides of 1, 1, and 1:

1 + 1 > 1

1 + 1 > 1

1 + 1 > 1

So this is a triangle.

For a triangle with the sides of 3, 3, and 9:

3 + 9 > 3

9 + 3 > 3

3 + 3 > 9   (this one is not true)

So, these can't be the values of the sides of a triangle.

For your situation, you have a triangle with sides of 4, 6, and x.

We need to find out what x is, so:

4 + 6 > x

4 + x > 6

6 + x > 4

Isolate x to one side and simplify all the inequalities. You will get:

x < 10

x > 2

x > -2

So, -2 < x < 10.

If you plug in your answer choices, it will be 9.

Answer: 1 and 1/10

Step-by-step explanation:

First you have to change the fractions denominator and that would become 5/10 and 6/10

Once you add them you get 1 and 1/10

Answer:

m=5 , a=3 x= 3 you get that by looking at the other numbers that they provided.

it's 7

Have a good day

Answer:

mp=cp+25%ofcp=1.25cp

discount=5%

discount amount=d%ofmp=5/100×0.25cp=0.0125cp

sp=mp-discount=1.25cp-0.0125cp=1.2375cp

profit%=(sp-cp)/cp×100%=(1.2375cp-cp)/cp×100%=0.2375cp/cp×100%=0.2375×100%=23.75%

Answer:

Step-by-step explanation:

5[tex]\frac{1}{2}[/tex]+2[tex]\frac{1}{7}[/tex]

5[tex]\frac{7}{14}[/tex]+2[tex]\frac{2}{14}[/tex]

7 9/14  or 7[tex]\frac{9}{14}[/tex]

Answer:

[tex] \frac{135}{14} [/tex]

Answer:

40%

Step-by-step explanation:

There's a total of 15 squares.

So the percentage that is gray would be [tex]\frac{6-gray-squares}{15-total-squares}[/tex] which simplifies to [tex]\frac{2}{5}[/tex] in fraction form or 40%

Answer:

2x-y=0

x=1/2y

Step-by-step explanation:

Answer:

Your solution is (1/2, 1).

Step-by-step explanation:

3х + Зу = -x + 5y

First we want to look at each side of the equation separately.

3х + Зу ⇒ This expression is fully simplified because you cannot add different variables together.

-x + 5y ⇒ This expression is fully simplified because you cannot add different variables together.

3х + Зу = -x + 5y

Now, let's bring the like terms together.

[add x to both sides]

x + 3x + 3y = -x + x + 5y

4x + 3y = 5y

[subtract 3y from both sides]

4x + 3y - 3y = 5y - 3y

4x = 2y

We want to solve for one variable at a time, so let's isolate x.

[divide both sides by 4]

4x/4 = 2y/4

x = 1/2y

Now we have an expression for x. Plug this expression in to your original equation.

3х + Зу = -x + 5y

3(1/2y) + 3y = -(1/2y) + 5y

According to PEMDAS (parentheses/exponents | multiplication/division | addition/subtraction), we should multiply first.

3(1/2y) + 3y = -(1/2y) + 5y

3/2y + 3y = -1/2y + 5y

Now let's add on each side.

9/2y = 9/2

Now we need to isolate y by dividing both sides by 9/2 (or multiplying by its reciprocal 2/9 ← This is often easier to understand when written)

[tex]\frac{2}{9} (\frac{9}{2} y) = \frac{9}{2} (\frac{2}{9} )[/tex]

In this form, we can see that the fractions cancel each other out.

y = 1

Now that we have the value of y, plug it into our equation for x.

x = 1/2y

x = 1/2(1)

Multiply.

x = 1/2

Your solution is (1/2, 1).

You're almost done! Check your answer by plugging in both these values in to your original equation.

3х + Зу = -x + 5y

3(1/2) + 3(1) = -(1/2) + 5(1)

Multiply.

3(1/2) + 3(1) = -(1/2) + 5(1)

3/2 + 3 = -1/2 + 5

Add.

9/2 = 9/2

This equation is true, therefore your answer is correct!

Hope this helps!

Answer:

171 cm³

Step-by-step explanation:

The object is composed of a cone and a cylinder.

Volume of the object = volume of cone + volume of cylinder

✔️Volume of Cone = ⅓πr²h

r = ½ of 6 = 3 cm

π = 3

h = 5 cm

Volume of cone = ⅓×3×3²×5

Volume of cone = 45 cm³

✔️Volume of cylinder = πr²h

π = 3

r = ½ of 6 = 3 cm

h = 14 cm

Volume of cylinder = 3×3×14

Volume of cylinder = 126 cm³

✔️Volume of the object = 45 + 126 = 171 cm³

Answer:

49:35

Step-by-step explanation:

Divide 49 and 35 and then you can Get Answer..

Answer:

Step-by-step explanation:

ratio of 49 cm to 35 cm

=> 49:35 { divide by 7}

=> 7:5 cm

Find the length of a side:

Length of side = √area

Side = √4

Side = 2 inches.

Now calculate Volume:

Volume = Side^3

Volume = 2^3

Volume = 8 cubic inches.
