The perimeter of the polygon is_______units.

Answer:

d. 3,200

Step-by-step explanation:

If the total population consists of 32,000 people, a sample of the population selected will consist of a number equal or less than 32,000 people.

From the given options, the only option that matches the above explanation is "D" which is less than 32,000 people.

Therefore, the correct answer choice is D. 3,200.

For part (a), you don't need to type in the "y=" portion as that is already done for you. For any answer choice involving a percentage, type in the number only. This is because the percent sign is already taken care of.

====================================================

Explanation:

Part (a)

Note how each time x goes up by 1, y drops by 0.2

We can see that

slope = rise/run

slope = (change in y)/(change in x)

slope = (-0.2)/(1)

slope = -0.2

This tells us that the battery life goes down by 20 percentage points for each hour. Note: This is not the same as saying it drops by 20% each time, as this is a subtle difference; however, I can see what your teacher is trying to say for part (b).

The y intercept is b = 1 since this is the location where the graph crosses the y axis.

The slope m = -0.2 and y intercept b = 1 leads y = mx+b to turn into y = -0.2x+1 which is the final answer for part (a).

As a way to check, plug in x = 0 and you should get y = 1. Plug in x = 1 and you should get y = 0.8, and so on. The (x,y) values should match what the graph shows.

----------------------------

Part (b)

As mentioned previously, the slope tells us how much the battery is changing. It's the rate of change. Specifically in this case, the battery is losing 20 percentage points for each hour. Your teacher should have used this careful phrasing, rather than say "the battery life goes down by 20% for each hour" but I can see what they're going for. So 20 is the answer for the first box of part (b)

The x intercept is where the graph crosses the x axis, which is x = 5 in this case. The x intercept always happens when y = 0. When y = 0, the battery is completely dead at 0%. Therefore, we can get 5 hours of battery life. The value 5 goes in the second box of part (b).

On the other end of the spectrum, the battery is 100% full when x = 0, which is at the start of everything. This is due to the y intercept b = 1.0 which represents 100%. In other words, the person starts off with a 100% charge, and they use their laptop for 5 hours, at which point the battery is at 0%. The value 100 goes in the third box for part (b)

----------------------------

Part (c)

We are asked to find the value of x when y = 0.75

y = -0.2x+1

0.75 = -0.2x+1

0.75-1 = -0.2x

-0.25 = -0.2x

-0.2x = -0.25

x = -0.25/(-0.2)

x = 1.25

After 1.25 hours the battery is at 75%

50 hopefully this will help you

Answer:

50

Step-by-step explanation:

Let "x" represent the number that makes them equal. No wet up a fraction;

[tex]\frac{5}{10}=\frac{x}{100}[/tex]

Step 1: Switch sides

[tex]\frac{x}{100}=\frac{5}{10}[/tex]

Step 2: Multiply both sides by 100

[tex]\frac{x}{100}\cdot \:100=\frac{5}{10}\cdot \:100[/tex]

Simplify

[tex]x=50[/tex]

Therefore, 50 is the number that will make the fractions equal.

Answer:

d = √(x2 - x2)^2 + (y2 - y1)^2 + (z2 - z1)^2

P1(0, 0, 0) P2(-9, 6, -4)

Substitute the values in the above equation and you will get

d = √(-9)^2 + (6)^2 + (-4)^2

= √(81 + 36 + 16)

= √133

= 11.53

Answer:

The answer is 11.53

Answer:

d = √(x2 - x2)^2 + (y2 - y1)^2 + (z2 - z1)^2

P1(0, 0, 0) P2(7, 3, 5)

Substitute the values in the above equation and you will get

d = √(7)^2 + (3)^2 + (5)^2

= √(49 + 9 + 25)

= √83

= 9.11

Answer:

63

Step-by-step explanation:

Answer:

27 cubic meters

Step-by-step explanation:

According to the scenario, computation of the given data are as follows,

Area of cube = 54 square meters

Let, Side = a

Then, Area of cube = 6[tex]a^{2}[/tex]

54 = 6 [tex]a^{2}[/tex]

[tex]a^{2}[/tex] = 9

a = 3

So, we can calculate the volume of cube by using following formula

Volume of cube = [tex]a^{3}[/tex]

By putting the value in the formula, we get

Volume of the cube = [tex]3^{3}[/tex]

= 27 cubic meters

Answer:

With replacement

[tex]probability \ of \ spade = \frac{13}{52} = \frac{1}{4} \\\\ probability \ of red\ card = \frac{26}{52} =\frac{1}{2}[/tex]

[tex]probability \ of \ spade \ then \ red\ card\ without\ replacement =[/tex][tex]\frac{1}{4} \times \frac{1}{2} = \frac{1}{8}[/tex]

Without replacement

[tex]probability \ of\ spade = \frac{13}{52} = \frac{1}{4} \\\\probability \ of \ spade\ again =\frac{12}{51} = \frac{4}{17}[/tex]

[tex]probability \ of \ spade \ then \ red\ card\ without\ replacement = \frac{1}{4} \times\frac{4}{17} =\frac{1}{17}[/tex]

Answer:

1.6 mi / hr

0.625 hr / mi

Step-by-step explanation:

4/2.5 = x / 1

2.5/2.5 = 1

So, 4 / 2.5 = 1.6

1.6 mi / hr

4= m

2.5 = hr

4 / 4 = 1

2.5 / 4 = 0.625

0.625 hours / mile

Answer:

8feet high

Step-by-step explanation:

To get the height of the pole, we will use the pythagoras theorem. Let H be the height

H²  = 10² -6²

H² = 100 - 36

H² = 64

H = √64

H = 8feet

Hence the pole is 8feet high

Answer:

H
