Answer:

I got 96.71ft 2 by doing it

It can be deduced that the area of the circle will be 26.42 feet.

It should be noted that the area of a circle is calculated by the formula:

= πr²

In this case, the radius is given as 2.9 feet. Therefore, the area of the circle will be:

= πr²

= 3.142 × 2.9²

= 26.42 feet

In conclusion, the area is 26.42 feet.

Answer:

The variance of the times between accidents is of 1849 days squared.

Step-by-step explanation:

Exponential distribution:

The exponential probability distribution, with mean m, is described by the following equation:

[tex]f(x) = \mu e^{-\mu x}[/tex]

In which [tex]\mu = \frac{1}{m}[/tex] is the decay parameter.

The variance of the exponential distribution is:

[tex]Var = \frac{1}{\mu^2}[/tex]

Assume that the mean time between accidents is 43 days.

This means that [tex]m = 43, \mu = \frac{1}{43}[/tex]

What is the variance of the times between accidents?

[tex]Var = \frac{1}{(\frac{1}{43})^2} = 43^2 = 1849[/tex]

The variance of the times between accidents is of 1849 days squared.

Answer:

8 pepper plants were sold.

Step-by-step explanation:

Assuming [tex]x=[/tex] the number of pepper plants sold, she sold [tex]7x[/tex] tomato plants and [tex]x[/tex] pepper plants, and since tomato plants sold + pepper plants sold = 64, we can turn this into the equation [tex]7x+x=64[/tex]. To solve this first we combine like terms to get [tex]8x=64[/tex]. Cancel the 8 by dividing both sides by 8 and we get [tex]x=8[/tex], which is the number of pepper plants sold. (We could also multiply x by 7 to get the number of tomato plants sold, which is 56.) Hope this helps!

x=7

Step-by-step explanation:

Answer:

Every quadrilateral's 4 angles add up to 360 degrees.

The four angles would be 100° + 7x +37 + 100° + 7x +37 = 360°

200° + 14x + 74° = 360°

14x = 360° - 274

14x = 86

x = 6.1428571429

Step-by-step explanation:

Answer: x=43/7

Step-by-step explanation:

One of the properties of the inner angle of a parallelogram is that the two angles on the same side add up to 180°

100+(7x+37)=180

100+7x+37=180

137+7x=180

137+7x-137=180-137

7x=43

x=43/7≈6.14

Answer:

0.525 = 52.5% probability that the two are from different families.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

In this problem, the order in which the two participants are selected is not important, so we use the combinations formula to solve this question.

Combinations formula:

[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

Desired outcomes:

1 from the Harfield family(from a set of 7).

1 from the McCoy family(from a set of 9). So

[tex]D = C_{7,1}*C_{9,1} = \frac{7!}{1!6!}*\frac{9!}{1!8!} = 7*9 = 63[/tex]

Total outcomes:

2 from a set of 16. So

[tex]T = C_{16,2} = \frac{16!}{2!14!} = 120[/tex]

Probability:

[tex]p = \frac{D}{T} = \frac{63}{120} = 0.525[/tex]

0.525 = 52.5% probability that the two are from different families.

Answer:

15.36mm

Step-by-step explanation:

The area of a triangle can be defined as B x H or L x H,

In your case, I'm assuming you meant base as length, so just plug into the equation:

L x H = 420.92mm2

27.4 x H = 420.92

H = 15.36

If you want to be exact, it is 15.3620438

The required height of the rectangle is 15.36 for the base of a rectangle is 27.4 mm and the area is 420.92 mm2.

The base of a rectangle is 27.4 mm.
The area is 420.92 mm2.
What is the height of the rectangle is to be determined.

The rectangle is 4 sided geometric shape whose opposites are equal in lengths and all angles are about 90°. Beside of square its pair of opposide sides are named as length and width sometimes base and height according to the mentions.

The area of a rectangle is a product of is two adjacent sides i.e. length * width

Area of the rectangle = height * base
420.92 = 27.4 * height
height = 420.92/27.4
height = 15.36

Thus, the required height of the rectangle is 15.36 for the base of a rectangle is 27.4 mm and the area is 420.92 mm2.

Answer:

450 ml.

Step-by-step explanation:

Volume of a cylinder:

The volume of a cylinder is given by:

[tex]V = \pi r^2h[/tex]

In which r is the radius and h is the height.

A cylindrical drinking glass has a base radius of 3.2 centimeters and a height of 14.0 centimeters.

This means that [tex]r = 3.2, h = 14[/tex]

How many milliliters of water does the glass hold when it is full?

Radius and height are measured in centimers, so the volume will be in cubic centimeters, which is the same as milliliter. So

[tex]V = \pi(3.2)^2*14 = 450.3[/tex]

Rounding to the nearest millimeter, the answer is 450 ml.
