Answer:
The error in the students work is
y -(-8) + 8 = -6x + 12 + 8
subtracting a negative is adding
y+8
They should subtract 8 from each side instead of adding 8 to each side
Step-by-step explanation:
We can use point slope form since we are given a point and the slope
y-y1 = m( x-x1)
y--8 = -6(x-2)
y+8 = -6(x-2)
Distribute the -6
y+8 = -6x+12
Subtract 8 from each side
y+8-8 = -6x+12-8
y = -6x+4
The error in the students work is
y -(-8) + 8 = -6x + 12 + 8
subtracting a negative is adding
y+8
They should subtract 8 from each side instead of adding 8 to each side
She should use 100 cups of pear juice, the way to get this is to multiply every number in the ratio by 20. 5×20=100
-2x + 4y = 22
-2x - 3y = 8
Subtract 2nd from 1st equation,
7y = 14
y = 14/7 = 2
Substitute it in 1st equation,
-2x + 4(2) = 22
-2x = 22 - 8
x = -14/2
x = -7
In short, Your Answer would be (-7, 2)
Hope this helps!
Answer:
a) 0.64
b) -1.13
Step-by-step explanation:
We are given the following information in the question:
Women:
Mean, μ = 64.2 inches
Standard Deviation, σ = 2.8 inches
We are given that the distribution of heights of women is a bell shaped distribution that is a normal distribution.
Men:
Mean, μ = 69.4 inches
Standard Deviation, σ = 3.0 inches
We are given that the distribution of heights of men is a bell shaped distribution that is a normal distribution.
Formula:
5.5 feet = 66 inches
a) z‑score for a woman 5.5 feet tall
b) z‑score for a man 5.5 feet tall
