Answer:
Step-by-step explanation:
1/4 inch to 3/8 ft = x inches to 1 ft
(1/4) / (3/8) = x / 1
cross multiply because this is a proportion
3/8x = 1/4
x = 1/4 * 8/3
x = 8/12 which reduces to 2/3 inches <==
It would most likely take 3-4 hours, maybe even 5.
Answer:
y = 12
Step-by-step explanation:
Given
Green = 28
Red = 35
Yellow = y
Prediction of yellow = 16 of 100
Required
Determine y
First, we need to calculate the probability of yellow.
Probability of yellow =
Probability = Yellow/Total
Where
Total = Yellow + Red + Green
Total = y + 35 + 28
Total = y + 63
So,
Probability = y/(y + 63)
Also, the prediction of yellow is 16 out of 100.
Represent this as probability.
Probability = 16/100
Equate both expressions to solve for y
y/(y + 63) = 16/100
y/(y + 63) = 0.16
Multiply both sides by (y + 63)
y = 0.16(y + 63(
y = 0.16y + 10.08
Collect like terms
y - 0.16y = 10.08
0.84y = 10.08
Solve for y
y = 10.08/0.84
y = 12
Answer:
c. None
Step-by-step explanation:
5x²- 3x+1=0 ax² + b + c = 0
discriminant: b² - 4ac = (-3)² - 4*5 * 1 = 9 - 20 = - 11 (negative)
discriminant < 0 2 imaginary solutions
Circle equation: (x - h) + (x - k) = r²
(h, k) = center
r = radius
The center is (-7, 4)
To find the radius, take the square root of 49.
√49 = 7
The radius is 7.
Best of Luck!
