Answer:

4V = 3U

Step-by-step explanation:

The final cost of a sale item is determined by multiplying the price on the tag by 75%.

Let us assume that the final cost of the sale item is V and the price on the tag is given by U.

Then the equation that best describes the function that represents the situation is V = \frac{75U}{100} =\frac{3U}{4}

⇒ 4V = 3U  (Answer)

At a certain college, 28% of the students major in engineering, 18% play club sports, and 8% both major in engineering and play
Alex

Answers: 0.286

Explanation:

Let E → major in Engineering

Let S → Play club sports

P (E) = 28% = 0.28

P (S) = 18% = 0.18

P (E ∩ S ) = 8% = 0.08

Probability of student plays club sports given majoring in engineering,

P ( S | E ) = P (E ∩ S ) ÷ P (E) = 0.08 ÷ 0.28 = 0.286

Y=4x+7 what are the intercepts of the line
VikaD [51]
To find the intercepts you sub the opposite value for 0 
To find y: 
<span>Y=4(0)+7
0*4=0+7=7
y=7

To find x: 
0=4x+7
Subtract 7 from both sides
-7=4x
divide both sides by 4

x=-7/4  

Final answer: 
x-intercept: (-7/4,0) 
y-intercept: (0,7) </span>
