Answer:
Slope = 0
So, the line is parallel to x-axis
Step-by-step explanation:
(x₁ , y₁) = (-8, -8) & (x₂ ,y₂) = (6 , -8)
![Slope = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\\=\frac{-8-[-8]}{6-[-8]}\\\\=\frac{-8+8}{6+8}\\\\= 0](https://tex.z-dn.net/?f=Slope%20%3D%20%5Cfrac%7By_%7B2%7D-y_%7B1%7D%7D%7Bx_%7B2%7D-x_%7B1%7D%7D%5C%5C%5C%5C%5C%3D%5Cfrac%7B-8-%5B-8%5D%7D%7B6-%5B-8%5D%7D%5C%5C%5C%5C%3D%5Cfrac%7B-8%2B8%7D%7B6%2B8%7D%5C%5C%5C%5C%3D%200)
Answer:
y=5x-37
Step-by-step explanation:
y-y1=m(x-x1)
y-3=5(x-8)
y=5x-40+3
y=5x-37
Answer: 1/4
Step-by-step explanation:
Let the volume of mixture (6%fat) in cup is 100cc
x cc be the volume of cream (18% fat) in the mixture.
∴
(100−x) cc be the volume of milk (2% fat) in the mixture.
x * 0.18+(100−x) * 0.02=100
⋅0.06 or 0.18x − 0.02x = 6−2 or 0.16x
= 4 or x=25 cc = 25%
Answer:
144 degrees
Step-by-step explanation:
9x + 27 = 6x + 66
3x + 27 = 66
3x = 39
x = 13
9(13) + 27 = 144
Answer: 0.29 (29%)
Step-by-step explanation:
women who gave birth at a certain hospital last year:
over 30 years old - 0.48
unmarried - 0.46
over 30 or unmarried (or both) - 0.65
what is the probability that a woman who gave birth at the hospital was both unmarried and over 30 ?
We know that
P(A and B) = P(A) + P(B) - P(A or B)
P(+30 and unmarried) = P(+30) + P(unmarried) - P(+30 or unmarried)
P(+30 and unmarried) = 0.48 + 0.46 - 0.65 = 0.29
