Answer:

4

Step-by-step explanation:

2+3+6+5 is 16 and since there are 4 numbers 16/4 is 4

Answer:

4

Step-by-step explanation:

To find average you must add up all of the numbers and then divide by the amount of numbers there are

2+3+6+5= 16

there are 4 numbers, so you do 16/4

16/4 = 4

Step-by-step explanation:

sin⁻¹ ((-√3) /2) : in third quadrant and 4th quadrant will produce negative sine value

sin⁻¹ ((-√3) /2) = - 60° (or - π/3)  or 240° and 300°

Step-by-step explanation:

The mid-segment of the triangle is always parallel to the base and is half the length of the base

Answer:

Length of the rectangle = 25 ft

Width of the rectangle = 5 ft

Step-by-step explanation:

Ratio of the width to the length is 1:5

So, let

Width = x

and length = 5x

Area of the rectangle = 125

[tex]x \times 5x = 125 \\ \\ 5 {x}^{2} = 125 \\ \\ {x}^{2} = \frac{125}{5} \\ \\ {x}^{2} = 25 \\ \\ x = \sqrt{25} \\ \\ x = 5 \: ft \\ \\ 5x = 5 \times 5 = 25 \: ft[/tex]

Length of the rectangle = 25 ft

Width of the rectangle = 5 ft

The length and the width of the rectangle are 25 ft and 5 ft respectively.

The area of a rectangle can be found by using the following formula:

Area = length * width

Let the constant be x, therefore the length is 5x and the width is x.

Area = length * width

125 = 5x*x

⇒125 = 5x²

⇒x² = 25

⇒x = √25

⇒x = 5

We can substitute the value of x to find the length and the width:

Length = 5x = 5*5 = 25 ft

Width = x = 5 ft

Thus, we have found the length and width of the rectangle to be 25 ft and 5 ft.

Answer:

6 pencils

Step-by-step explanation:

30/5=6

Answer:36

Step-by-step explanation: 6 sided dice = 6 possible outcomes

6×6=36

The required number of outcomes is 36 after rolling all six dice. Option B is correct.

Jane has to roll a set of six standard dice and record the results of each
trial. She wonders how many different outcomes are possible after rolling all six dice. the total number of possible outcomes for each trial to be determined.

Probability can be defined as the ratio of favorable outcomes to the total number of events for a system of the certain events.

For 1 dice, sample space = { 1  2  3  4  5  6}
total possible outcome = 6
Now 6 dice roll at once and the total outcome = 6 * 6
                                                                                = 36
Meanwhile, Jane has a total of 36 outcomes.

Thus, the required number of outcomes is 36 after rolling all six dice. Option B is correct.

Answer and Explanation:

If, on the other hand, the graph "flexes" or "flattens out" to some degree when it goes to cross the axis, then the zero is of a higher multiplicity; that is, it'll be of multiplicity three, five, or higher.

When a graph doesn't start at 0, it means that the graphs before it is not shown.

For number 4, I'd suggest Graph 3.

For number 3, I'd suggest graph 1.

For number 5, Write something along the lines of "Graph 2 does not show the car stopping slowly, it stops suddenly. Then it starts going really fast and stops suddenly again."

Answer:

$600

Step-by-step explanation:

[tex]20\% \: of \: 750 \: is = [/tex]

[tex] \frac{20}{100} \times 750[/tex]

[tex] = 150[/tex]

Subtract 150 from 750 to get discount price

[tex]750 - 150 \\ = 600[/tex]

Therefore, the discount price is $600

Answer: m ≥ 13

m + 7 ≥ 20

Answer:

The margin of error for a 95% confidence interval is 0.199.

Step-by-step explanation:

We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:

[tex]\alpha = \frac{1 - 0.95}{2} = 0.025[/tex]

Now, we have to find z in the Ztable as such z has a pvalue of [tex]1 - \alpha[/tex].

That is z with a pvalue of [tex]1 - 0.025 = 0.975[/tex], so Z = 1.96.

Now, find the margin of error M as such

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.

Assume that the population standard deviation is 2.8.

This means that [tex]\sigma = 2.8[/tex]

760 millennials (18- to 33-year-olds)

This means that [tex]n = 760[/tex]

Give the margin of error for a 95% confidence interval.

[tex]M = z\frac{\sigma}{\sqrt{n}} = 1.96\frac{2.8}{\sqrt{760}} = 0.199[/tex]

The margin of error for a 95% confidence interval is 0.199.

Answer:

Step-by-step explanation:

a 30-60-90 right triangle is a right triangle because of the 90

the 30 and the 60 have to make 90 too since traingles make 180

30 + 60 + 90 = 180

so 30-60-90 is a right triangle.

Right triangles also can use pythagoran theorem, so the angle ratio is

30-60-90

but the side ratio is

Answer:

Sofia will be 19 years old

Step-by-step explanation:

First:

What know that David is 30 right now.

David=30

We also know that David is 7 years older than Mark, meaning that David-7=Mark

30-7=23        -Mark

And last we know that Mark is 4 years older than Sofia So we would do 23-4 to get Sofia age,

23-4=19        -Sofia

So in conclusion...

SOFIA: 19  

MARK: 23

DAVID: 30
