Answer:
59.48%
Step-by-step explanation:
To determine the probability you have to calculate the z score which is equivalent to the number of standard deviations you are from the mean.
x is the value you want to know its probability
μ is the mean
σ is the standard deviation
A z score of -0.24 means you are 0.24 standard deviation at the left of the mean, the probability associated to a z of -0.24 can be found in a z table and it is 40.52%.
That probability cover the minimum value until 12 minutes, so the probability to need more than 12 minutes is 100 - 40.52 = 59.48%

Answer:
(4, 5)
Step-by-step explanation:
y = 2x - 3
y = 7 - 0.5x
y is already isolated on both equations, set them equal to each other:
2x - 3 = 7 - 0.5x
add 3 to both sides:
2x = 10 - 0.5x
add 0.5x to both sides:
2.5x = 10
divide by 2.5:
x = 4
plug in 4 for x on either equation and solve for y:
y = 2(4) - 3
y = 8 - 3
y = 5
(4, 5)

Answer:
24 square feet
Step-by-step explanation:
The area of a rectangle is the product of its dimensions:
A = LW
A = (8 ft)(3 ft) = 24 ft²
The area of the countertop is 24 square feet.
The correct answer would be
B.(x-2)(3x)+(x-2)(4)
When distributing you just break up the second parentheses and put the first parentheses infront of both of them, as it is shown in this answer.
