If the radius of the circle is 7 cm, find its area, rounded to 2 decimal places.
A= _______ cm2
Answer:
153.94
Step-by-step explanation:
The formula for area is pi*radius^2
the radius is 7, so we do pi7^2 which is 49pi
49pi is 153.93804 which is 153.94 rounded to two decimal places

Step-by-step explanation:
A player pays $15 to play a game in which a chip is randomly selected from a bag of chips. The bag contains 10 red chips, 4 blue chips, and 6 yellow chips. The player wins $5 if a red chip is
selected, $10 if a blue chip is selected, and $20 if a yellow chip is selected. Let the random variable X represent the amount won from the selection of the chip, and let the random variable W
represent the total amount won, where W= X - 15. What is the mean of W?
$10.50
B
$4.50
-$4.50
D
- $6.50
E
-$10.50
Answer:
C. -$4.50
Step-by-step explanation:
To find the mean of W we must first find the mean of X. So, 10/20*5+4/20*10+6/20*20=10.5
Then because mean is impacted by transformations, the mean of W=the mean of X-15=10.5-15=-$4.50
Here we need to find the expected value of the given probabilistic game.
The correct option is B: -$4.50
-------------------------------
For an event with outcomes {x₁, x₂, ...}, each one with probability {p₁, p₂, ...}, the expected value is defined as:
[tex]EV = x_1*p_1 + x_2*p_2 + ...[/tex]
Here the outcomes are:
x₁ = winning $5.
This happens if a red chip is selected, and there are 10 red chips in a bag of 20 chips, so the probability is:
p₁ = 10/20 = 1/2
x₂ = winning $10
This happens if a blue chip is selected, and there are 4 blue chips out of 20 chips, so the probability is:
p₂ = 4/20 = 1/5
x₃ = winning $20
This happens if a yellow chip is selected, and there are 6 of these in a total of 20, then the probability is:
p₃ = 6/20 = 3/10
Now we can compute the expected value:
[tex]EV = \$ 5*(1/2) + \$ 10*(1/5) + \$ 20*(3/10) = \$ 10.50[/tex]
Now if you also take in mind that you need to pay $15.00 to play, we will see that the mean of W, the amount that you won, is:
W = $10.50 - $15.00 = -$4.50
Which means that in average, you lose $4.50

A man buys furniture that has a list price of $255. He is allowed a discount of 12%
but must pay a sales tax of 3% on the cost. Which of the following is the amount he
actually pays for the furniture:
(A) $217.67
(B) $231.13 (C) $224.40 (D) $232.50 (E)
none of these.
Answer:
Option B. $231.13 is the correct answer.
Step-by-step explanation:
Given that
Listed price of furniture = P = $255
Discount = d = 12%
Sales tax = s = 3%
First of all, we have to find the discounted price by calculating the discount first
So,
[tex]Discount = 12\%\ of\ P\\= 0.12*255\\= 30.6[/tex]
Discounted Price:
[tex]= Listed\ Price - Discount\\= 255 - 30.6\\= 224.4[/tex]
The sales tax will be calculated on the discounted price
So,
[tex]Sales\ tax = 3\%\ of\ Discounted\ price\\= 0.03 * 224.4\\= 6.732[/tex]
Now,
[tex]Final\ price\ of\ furniture = Discounted\ price + Sales\ tax\\= 224.4 + 6.732\\=231.132[/tex]
He will actually pay $231.132 for the furniture.
Hence,
Option B. $231.13 is the correct answer.

The perimeter of a rectanglar field is 334 yards. If the widths the field is 78 yards, what is its length
Answer:
The length of rectangular field is 129 yards.
Step-by-step explanation:
Given that
Perimeter = P = 334 yards
Width = w = 78 yards
Length = l = ??
We will use the perimeter of the formula to find the length of rectangle.
The perimeter of a rectangle is given by:
[tex]P = 2(l+w)[/tex]
Putting the values of perimeter and width
[tex]334 = 2(l+38)\\334 = 2l+76\\334-76 = 2l+76-76\\258 = 2l\\\frac{2l}{2} = \frac{258}{2}\\l = 129[/tex]
Hence,
The length of rectangular field is 129 yards.

Evalulate 7 3/4+(-2 1/5) x for x =-10
Answer:
2884
Step-by-step explanation:
First plug in -10 for x, which would look like this: 734 + (-215 * (-10) ) =
Then, first you calculate everything in the parenthesis, which is (-215) * (-10)
and the equation would look like this after you multiply: 734 + 2150 =
If you noticed the number turned out positive after we multiplied, that is because - number times a - number would always be positive, just like if you divide - number by a - number your answer would be positive.
Your last step would be adding 734 with 2150. : 734 + 2150 = 2884
+ 734
2150
_____
2884
And the answer would be 2884
What is the equation of the line that passes through the point (-6, -2) and has a
slope of 1/6
Step 1: Determine b by using the point (-6,-2), the given slope, and the slope intercept formula, y = mx + b.
[tex]y = mx + b\\\\-2 = \frac{1}{6}(-6) + b\\\\-2 = -1 + b\\\\-1 = b[/tex]
Step 2: Now that we have b, we can determine the equation of the line.
[tex]y = \frac{1}{6}x -1[/tex]
I didn't use + (-1) because b is negative. Therefore you need to change the equation from y = 1/6x + (-1) to y = 1/6x - 1.
Hypotenuse a =?; b =40; c=50
a² = b² + c²
a² = 40² + 50²
a² = 1600 + 2500
a² = 4100
a = √4100
a = 64.03

The height of a cylinder with a fixed radius of 6 cm is increasing at the rate of 3 cm/min. Find the rate of change of the volume of the cylinder (with respect to
time) when the height is 20 cm.
A. 36Pi
B. 108pi
C. 360pi
D. None of these
Answer:
108π cm^3/min
Step-by-step explanation:
At a time of t min, let the height be h cm
The volume of a cylinder;
V = π r^2 h
= 36π h
differentiating both sides with respect to t;
dV/dt = 36π dh/dt
but dh/dt = 3 cm/min
dV/dt = 36π(3) = 108π cm^3/min
