Your answer
Answer:
Circumference of circle = 138.28 cm (Approx.)
Area of circle = 1,521.11 cm² (Approx.)
Step-by-step explanation:
Given:
Radius of circle = 22 cm
Find:
Circumference of circle
Area of circle
Computation:
Circumference of circle = 2πr
Circumference of circle = 2(22/7)(22)
Circumference of circle = 2(3.1428)(22)
Circumference of circle = 138.2832
Circumference of circle = 138.28 cm (Approx.)
Area of circle = πr²
Area of circle = (22/7)(22)²
Area of circle = (3.1428)(22)(22)
Area of circle = 1,521.1152
Area of circle = 1,521.11 cm² (Approx.)

Step-by-step explanation:
Thirty percent of credit card holders carry no monthly balance, while 70% do. Of those card holders carrying a balance, 30% have annual income $20,000 or less, 40% between $20,001 - $50,000, and 30% over $50,000. Of those card holders carrying no balance, 20%, 30%, and 50% have annual incomes in these three respective categories.
a) What is the probability that a randomly chosen card holder has annual income $20,000 or less?
b) If this card holder has an annual income that is $20,000 or less, what is the probability that (s)he carries a balance?
Answer:
a) 0.27 = 27% probability that a randomly chosen card holder has annual income $20,000 or less.
b) 0.778 = 77.8% probability that (s)he carries a balance
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]
In which
P(B|A) is the probability of event B happening, given that A happened.
[tex]P(A \cap B)[/tex] is the probability of both A and B happening.
P(A) is the probability of A happening.
a) What is the probability that a randomly chosen card holder has annual income $20,000 or less?
20% of 30%(carry no balance).
30% of 70%(carry balance). So
[tex]P = 0.2*0.3 + 0.3*0.7 = 0.06 + 0.21 = 0.27[/tex]
0.27 = 27% probability that a randomly chosen card holder has annual income $20,000 or less.
b) If this card holder has an annual income that is $20,000 or less, what is the probability that (s)he carries a balance?
Conditional probability.
Event A: Annual income of $20,000 or less.
Event B: Carries a balance.
0.27 = 27% probability that a randomly chosen card holder has annual income $20,000 or less
This means that [tex]P(A) = 0.27[/tex]
Probability of a income of $20,000 or less and balance.
30% of 70%, so:
[tex]P(A \cap B) = 0.3*0.7 = 0.21[/tex]
The probability is:
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.21}{0.27} = 0.778[/tex]
0.778 = 77.8% probability that (s)he carries a balance

Step-by-step explanation:
Solve this simultaneous equation x+2y=11
x-2y=1
Answer:
Equation 1,
[tex]x + 2y = 11[/tex]
Equation 2,
[tex]x - 2y = 11[/tex]
Take equation number 2.
[tex]x - 2y = 11 \\ x = 11 + 2y[/tex]
Substitute 'x' in Equation number 1.
[tex]x + 2y = 11 \\ 11 + 2y + 2y = 11 \\ 11 + 4y = 11 \\ 4y = 11 - 11 \\ 4y = 0 \\ y = \frac{0}{4} \\ y = 0[/tex]
y = 0.
So x,
[tex]x = 11 - 2y \\ x = 11 - 2(0) \\ x = 11 - 0 \\ x = 11[/tex]
x = 11.
Answer:
using elimination method multiply both equations by 2...then subtract equation 2 from 1
Find the surface area of each figure to the nearest tenth.
Answer:
A≈471.24 is the surface area of the cylinder
58m^2 is the surface area of the triangular prism
Step-by-step explanation:
Solution
A=2πrh+2πr2=2·π·5·10+2·π·52≈471.2389
Triangle area formula
area = 0.5 * b * h , where b is the length of the base of the triangle, and h is the height/altitude of the triangle.
4(2.5)+8(6)
10+48=58m^2

A rectangular pool is being constructed with a length that is four times the width. There will be a walkway constructed around the pool that is 6 feet wide all around. Write a factored expression for the area in square feet of the pool and the walkway combined.
Answer:
(4x²+36) feet²
Step-by-step explanation:
Area of the pool = L × W
Take width as x and Length as 4x
4x × x = (4x²)feet² {area of pool}
Area of walkway = L × W
6 × 6 = 36feet²
Total area = 4x² + 36 feet²

Find the value of y. geometry!!
Answer:
y = 54
Step-by-step explanation:
Once again we are going to use the inscribed angle and intercepted arc relationship where the inscribed angle is equal to half of the measure of the intercepted arc.
Angle "y" is the inscribed angle and its intercepted arc has a measure of 108°
So y = one half of 108
[tex]\frac{108}{2} =54[/tex]
So we can conclude that y = 54
Mario traced this trapezoid.
Answer:
84sq. in
Step-by-step explanation:
Area of the rectangle = length * width
Given
Length = 7in
Width = 12in
Area of the rectangle = 7in * 12in
Area of the rectangle = 84sq. in
Hence the area of the rectangle is 84sq. in
