(3/4) / 1 = x / (2/3).....3/4 oil to 1 cup vinegar = x oil to 2/3 cups of vinegar
cross multiply because this is a proportion
(1)(x) = (3/4)(2/3)
x = 6/12 reduces to 1/2 cup of oil <===

A. 3/19 <br><br> B. 4/19<br><br> C. 1/5<br><br> D. 5/19
DanielleElmas [232]

P(B|A)=\dfrac{P(A \cap B)}{P(A)}\\\\ |\Omega|=20\cdot19=380\\ |A|=5\cdot19=95\\ |A\cap B|=5\cdot4=20\\\\ P(A)=\dfrac{95}{380}=\dfrac{1}{4}\\ P(A \cap B)=\dfrac{20}{380}=\dfrac{1}{19}\\\\ P(B|A)=\dfrac{\dfrac{1}{19}}{\dfrac{1}{4}}=\dfrac{1}{19}\cdot4=\dfrac{4}{19}\Rightarrow B

What is the slope of the line that passes through the points (7, -9) <br>and (15, -29)?
vekshin1

answer: 4.75

Step-by-step explanation:

To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points. Which means, y1 - y2 / x1 - x2 = 29 - (-9) / 15 - 7

= 29 + 9 / 8

= 38/8

=4.75
