can i get some help on this please ​

First, find the area of the table...

d = 4 ft  ---> r = 2 ft

Area = 3.14 * (2 ft)² = 12.56 ft²

Find how many pads will cover the entire table. Since each pad is 1 ft²...

# of pads = 12.56 ft² / 1 ft² = 12.56

Find the total cost for all pads...

Total cost = 12.56 * $0.75 = $9.42

The formula Sabine should use for calculating the variance and standard deviation for the random sample of bamboo stalks are,

[tex]s^2=\dfrac{(x_1-\overline x)^2(x_2-\overline x)^2...(x_n-\overline x)^2}{n-1}[/tex]

[tex]s=\sqrt{\dfrac{(x_1-\overline x)^2(x_2-\overline x)^2...(x_n-\overline x)^2}{n-1}}[/tex]

The variance of the data is the measure of average level by which every point is differed from the mean.

It can be calculated as,

[tex]s^2=\dfrac{(x_1-\overline x)^2(x_2-\overline x)^2...(x_n-\overline x)^2}{n-1}[/tex]

The standard deviation of the data is the half of the difference of the highest value and mean of the data set.

It can be calculated as,

[tex]s=\sqrt{\dfrac{(x_1-\overline x)^2(x_2-\overline x)^2...(x_n-\overline x)^2}{n-1}}[/tex]

Sabine records the daily heights of a random sample of bamboo stalks, in inches.

They are: 20, 19, 17, 16, 18, 15, 20, 21

For this data Sabine wants to calculate the variance and standard deviation, which can be done using the above formula.

Hence, the formula Sabine should use for variance is,

[tex]s^2=\dfrac{(x_1-\overline x)^2(x_2-\overline x)^2...(x_n-\overline x)^2}{n-1}[/tex]

The formula should Sabine use for standard deviation,

[tex]s=\sqrt{\dfrac{(x_1-\overline x)^2(x_2-\overline x)^2...(x_n-\overline x)^2}{n-1}}[/tex]

Answer:

angle 1: 30

angle 2: 41

angle 3: 96

Step-by-step explanation:

So the angles' sum in one triangle is 180 degrees so you know two of the first triangle's angles so you sum them up and you get: 150 so now you subtract that from 180 and get 30.

Now you can see that if you want to get angle 2 you need to get angle 3 first. so you can see that the 84 degrees is on the same line as angle 3 so, we also know that a line is 180 degrees. so 180-84=96.

Now to get angle 2 we just simply sum up 43 and 96 which is 139, then we subtract that from 180, then we get 41.

Using the slope concept, it is found that the ship is sunken at a depth of 357 meters.

The slope is given by the vertical change divided by the horizontal change, and it's also the tangent of the angle of depression.

In this problem:

Hence, applying the slope:

[tex]\tan{55^\circ} = \frac{d}{250}[/tex]

[tex]d = 250\tan{55^\circ}[/tex]

[tex]d = 357[/tex]

The ship is sunken at a depth of 357 meters.

Check the picture below.

The value of variables x and y are,

x = 1 and y = 188

An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.

Given that;

In the diagram, quadrilateral HIJK is inscribed in circle L.

Now, We know that;

sum of opposite angle are 180 degree.

Hence, We get;

∠H + ∠J = 180

67 + (y - 75) = 180

y - 8 = 180

y = 180 + 8

y = 188

And, We get;

∠I + ∠K = 180°

96 + (x + 83) = 180

x + 179 = 180

x = 180 - 179

x = 1

Thus, The value of variables x and y are,

x = 1 and y = 188

Answer:

27 over 4

Step-by-step explanation:

To solve this, work on each side, one at a time.

Since there are variables, replace them with the numbers provided.

7x - 3y

over

2x + y

Can be translated to...

7 * 3 - 3 * -2

over

2 * 3 + -2

Let's work with the top side first.

7 * 3 - 3 * -2

Remember the order of operations (Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction)

Keep in mind that Multiplication and Division as well as Addition and Subtraction are done in the order shown in the problem.

Let's start by doing the multiplication...

21 - (-6)

Then the subtraction!

27!

Now for the bottom side...

2 * 3 + -2

Multiply first.

6 + -2

Then add!

Answer:

X=46 ft.

Step-by-step explanation:

Write an equation to solve the problem.

Since one side is 3 ft, don’t forget that there is another side of the rectangle that is also 3 ft. We can add this part to the equation as 2(3).

Now, let’s see the other side. It’s (2+x) ft. As mentioned before, there are another side, so, you guessed it: 2(2+x).

We have our equation:

2(3)+2(2+x) = 102 ft.

Simplify first:

6+4+2x = 102 ft.

10+2x=102 ft.

2x=92 ft.

x=46 ft.
