Answer:

200.96 yd^2

Step-by-step explanation:

Area of a circle = πr^2 where r = radius

radius = diameter/2

radius = 16/2

radius = 8

Area = π(8)^2

Area = π64

Area = 200.96 yd^2

Linda throws a dart that hits the square shown below: A square is drawn. A circle of radius 9 units touches the sides of the squ

nataly862011 [7]

Probability helps us to know the chances of an event occurring. The probability of Linda's dart hitting the circle is 0.7857.

<h3>What is Probability?</h3>

The probability helps us to know the chances of an event occurring.

$\rm{Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}$

As it is given that the circle touches the sides of the square. therefore, the length of the side of the square is the diameter of the circle.

Now, in order to calculate the probability that the dart hits a point in the circle we need to calculate the area of the circle and the area of the square.

Area of the circle with a given radius of 9 units,

$\text{Area of the circle} = \pi r^2$

$\rm = \pi \times (9^2)\\\\= 81\pi\ units^2$

Area of the square with sides equal to the diameter of the circle,

$\rm \text{Area of square} = side^2$

$\rm = Diameter ^2\\\\= (2 \times radius)^2\\\\= (2 \times 9)^2\\\\= 18^2\\\\= 324\ units^2$

Now, the probability that the dart hits a point in the circle can be written as,

$\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}\\\\\\Probability=\dfrac{\text{Area of the circle}}{\text{Area of square}}\\\\\\Probability=\dfrac{81 \pi}{324} = 0.7857$

Hence, the probability of Linda's dart hitting the circle is 0.7857.

An internet company randomly selected 50 of its customers and asked them how many hours per week they use the internet. Of those

LenKa [72]

Answer:

Number of person use more than 15 hours per week from 800 subscribers = 448

Step-by-step explanation:

Given:

Total number of sample = 50

Result = 28 Person use more than 15 hours per week

Find:

How many people use more than 15 hours per week

Computation:

⇒ Probability of Person use internet more than 15 hours per week = 28 / 50

⇒Probability of Person use internet more than 15 hours per week = 0.56

⇒Number of person use more than 15 hours per week from 800 subscribers = 800 × Probability of Person use internet more than 15 hours per week

⇒Number of person use more than 15 hours per week from 800 subscribers = 800 × 0.56

⇒ Number of person use more than 15 hours per week from 800 subscribers = 448

A teacher has a 2-gallon (52 cup) container of juice. She gives each student z cup of juice. Which equation represents the amoun

matrenka [14]

Answer:

$y = 32 - \frac{1}{2}x$

Step-by-step explanation:

Given

$Cups = 32$ ---- not 52

$Students = x$

$Remainder = y$

$Each = \frac{1}{2}$ --- not z

Required

The equation for y

The remainder y is calculated as:

$y = Cups - Students * Each\\$

$y = 32 - \frac{1}{2}x$

2 tenths plus 4 hundredths equal --blank-- hundredths

kondaur [170]

2/10 is the same at 20/100 (because you times both top and bottom by 10)
20/100 + 4/100 = 24/100
This could be simplified to 12/50 or 6/25.
Hope this helps :)
