Work out the area of this circle take (pi) to be 3.142 and give your answers to 2 decimal places

Answer:

See below.

Step-by-step explanation:

The first thing to do is to put all the numbers in order.

[tex]7, 8, 9,10,12,13,14,15[/tex]

First, let's find the mode.

The mode is where there is a repeating number in a set. If you look, there is no repeating number. Which means, there is no mode for this set.

Next, we find the median.

[tex](10 + 12) / 2 = 11[/tex]

The median would be [tex]11[/tex].

Then, we find the mean.

For the mean, you add up all the numbers and you will divide it by how many numbers there are.

[tex]7,8,9,10,12,13,14,15 = 88[/tex]

[tex]88 / 8 = 11.[/tex]

The mean is [tex]11[/tex].

Answer:

C

Step-by-step explanation:

Is is a one-tailed test

P(z < 2.45) = 0.9929

1 - 0.9929 = 0.0071

Significant at both 0.05 and 0.01 because both are greater than 0.0071

Answer:

The finding is significant at both α = 0.05 and α = 0.01.

2w=24, w=12 feet

Answer:

mean= 12.8

median=13

mode=there is no mode

Step-by-step explanation:

mean/average=14+10+12+15+ 13​=64/5=12.8

median=10,12,13,14,15=13

mode= is the number that repeats more often. = there is no mode

Answer:

36 times larger.

Step-by-step explanation:

V= [tex]\pi *r^{2}*\frac{h}{3}[/tex] is the original volume of a cone formula.

If the radius is multiplied by 6 the new formula is:

V= [tex]\pi *(6x)^{2} * \frac{4}{3}[/tex]

Which is simplified to:

V= [tex]\pi *36r^2*\frac{h}{3}[/tex]

The only difference between the simplified formula and the original is the *36 so the new volume is 36 times larger when the radius is multiplied by 6.

Answer:

2.25 pounds

Step-by-step explanation:

The diagram showing the weight of bags with grapes is shown in the attached file below.

From the diagram; number of  bags of grapes that had a weight of [tex]\dfrac{3}{8}[/tex] pounds or less is:

[tex]\dfrac{3}{8}[/tex] pounds  = 3

[tex]\dfrac{1}{4}[/tex] pounds = 4

[tex]\dfrac{1}{8}[/tex] pounds = 1

Thus; the total is = 3+4+1 = 8

However, The total weight of the grapes in the bag that had a weight of  [tex]\dfrac{3}{8}[/tex] pounds or less is :

= [tex]\dfrac{3}{8}(3) + \dfrac{1}{4}(4) + \dfrac{1}{8}(1)[/tex]

= [tex]\dfrac{9}{8} + 1 + \dfrac{1}{8}[/tex]

= [tex]\dfrac{9+8+1}{8}[/tex]

= [tex]\dfrac{18}{8}[/tex]

= 2.25 pounds

Answer:

Area of the lawn is watered by the sprinkler is 392.75 ft²

Step-by-step explanation:

As the  lawn sprinkler  rotate 50 degrees when it project water out, it makes an arc from the corner where it is located.

The area of the lawn in which the water sprinkles, forms a sector with an angle of 50 degrees and radius of 30.0 feet.

[tex]Area \ of \ sector = Area \ of \ lawn= \frac{\theta}{360} \pi r^2\\\\ Area \ of \ lawn= \frac{50}{360} \pi (30)^2 = 392.75 \ ft^2[/tex]

Therefore, area of the lawn is watered by the sprinkler is 392.75 ft²

Answer:

The shaded segment  = The arc area - The triangle

The arc area = pi x radius^2 x angle/360

                     = pi x 9^2 x (360-270)/360 = 63.61 (m2)

The triangle area = 9 x 9/2 = 41.5 (m2)

(because this is right triangle)

=> The shaded segment = 63.61 - 41.5 = 22.11 (m2)

Answer:

Leila would make a profit of $48

Step-by-step explanation:

~ Knowing that there is some sort of proportion that can be formed through Leila and Jo's profit, we could form even a proportionality to compute the profit Leila makes given jo's profit of $60 ~

If is is known that Leila: Jo, 4: 5, we could form such a proportion:

4                5       ⇒     where x - Leila's profit knowing Jo's profit of $60

x               60

Now let us solve for x, through cross multiplication:

5x = 60 * 4,

5x = 240,

x = profit of $48

Answer:

B

Step-by-step explanation:

[tex]2x^{4}y - 18x^{2}y^{3}[/tex]

Both sides have [tex]x^{2}[/tex]

[tex]x^{2} (2x^{2}y - 18y^{3})[/tex]

Both sides have y

[tex]yx^{2} (2x^{2} - 18y^{2})[/tex]

Both sides have 2

[tex]2yx^{2} (x^{2} - 9y^{2})[/tex]

[tex]x^{2} = x.x\\9y^{2} = 3y. 3y[/tex]

[tex](x^{2} - 9y^{2}) = (x +3y) (x-3y)[/tex]

The factored expression is 2x²y(x + 3y)(x- 3y), and option (B) is correct.

The act of expressing a number or other mathematical object as the sum of numerous factors is known as factorization.

The given expression is 2x⁴y-18x²y³.

Factor the expression as follows:

2x⁴y-18x²y³

= 2x²y(x² - 9y²)

= 2x²y(x² - (3y)²)

= 2x²y(x + 3y)(x- 3y)

Hence, the factored expression is 2x²y(x + 3y)(x- 3y), and option (B) is correct.
