what is the area of a semicircle with a diameter of 8

9514 1404 393

Answer:

  1. 6.1 to 10.3

  2. 9.6 hours

  3. 7.5 hours

Step-by-step explanation:

1. The empirical rule or the supplied chart will tell you that μ ±3σ of the distribution is within 99.7% of the mean. Here, that is ...

  8.2 ±3(0.7) = 8.2 ±2.1 = [6.1, 10.3]

The range of hours is 6.1 to 10.3 hours.

__

2. 2.5% of the distribution is above μ +2σ, or ...

  8.2 +2(0.7) = 9.6 . . . hours

__

3. The bottom 16% of the distribution is below μ -σ, or ...

  8.2 -0.7 = 7.5 . . . hours

Answer:

18541.89/9 = $2060.21 is the answer

Step-by-step explanation:

Total college tuition = $18541.89

Number of equal payments = 9

Equal payments = 18541.89/9

                           = $2060.21

(a) A trapezoid has only 1 pair of parallel sides but a parallelogram has 2

Step-by-step explanation:

Required

The difference between a trapezium and a parallelogram

The major difference is:

A trapezium has a pair of parallel side, the other sides are not parallel

A parallelogram has 4 sides where opposite sides are parallel (i.e 2 pairs of parallel sides).

Hence, (a) is correct

Answer:

Mode

Step-by-step explanation:

Measures of central tendency:

The 3 most common measures of central tendency are: The mean, the median, and the mode.

The mean is the average value.

The median separates the lower 50% of the values from the upper 50% of the values.

The mode is the value that appears the most times in the data-set.

In this question:

To find the doughnut you should make more, you should have to know which has the biggest interest from clients, that is, the one that is sold the most, which means that the mode should be used.

Answer:

Mode

Answer:

A. 84 pi feet^2

Step-by-step explanation:

So the lateral area is the rectangular piece on the net

In order for it to be an actual cylinder the 2 circles are congruent

Therefore the radi, area, circumference ect.. are the same.

So the only missing measurement we need to find the lateral area is the length of the rectangular piece

If you visualize a cylinder, the rectangular piece goes around the perimeter/circumference of the circle

So that means that the length of the rectangle is the circumference of the circle

Circumference = 2*pi*r

2 * pi * 6

= 12 pi

Then 7*12 pi

=84 pi

So the lateral area is 84 pi

Answer:

x = 11

Step-by-step explanation:

interior angles of a triangle = 180

equation:

⇒ 82 + 31 + 6x + 1 = 180

combine like terms:

⇒ 82 + 31 + 6x + 1 = 180

⇒ 114 + 6x = 180

subtract 114 on both sides:

⇒ 114 - 114 + 6x = 180 - 114

⇒ 6x = 66

divide 6 on both sides:

⇒ 6x = 66

⇒ [tex]\frac{6x}{6} = \frac{66}{6}[/tex]

⇒ x = 11

Quarters  ≡ Dimes ≡  Nickels ≡  Pennies

23             ≡   29      ≡  17           ≡  38

Answer:

[tex]P(Q\ or\ P) = 0.5701[/tex]

Step-by-step explanation:

Given

[tex]Quarters = 23[/tex]

[tex]Dimes = 29[/tex]

[tex]Nickels = 17[/tex]

[tex]Pennies = 38[/tex]

First, we calculate total number of coins

[tex]Total = 23 + 29 + 17 + 38[/tex]

[tex]Total = 107[/tex]

The probability of obtaining quarter (Q) of penny (P) is:

[tex]P(Q\ or\ P) = P(Quarters) + P(Pennies)[/tex]

[tex]P(Q\ or\ P) = \frac{n(Quarters)}{Total} + \frac{n(Pennies)}{Total}[/tex]

Take LCM

[tex]P(Q\ or\ P) = \frac{n(Quarters) + n(Pennies)}{Total}[/tex]

[tex]P(Q\ or\ P) = \frac{23 + 38}{107}[/tex]

[tex]P(Q\ or\ P) = \frac{61}{107}[/tex]

[tex]P(Q\ or\ P) = 0.5701[/tex]

Answer:

A.) 11%

Step-by-step explanation:

Step 1) There are 9 favorable outcomes but only 1 outcome is possible, so that leaves us with a fraction of: [tex]\frac{1}{9}[/tex]

Step 2) Then we need to turn this into a decimal to find the percentage:

1 ÷ 9 = 0.111111111...

Step 3) We now need to turn this into a percent:

0.11 x 100% = 11%
