Answer:
Mercedes, look at the graph i'm attaching... do you see ? what's the slope?
Step-by-step explanation:
I'm pretty sure the answer is D. because I don't think anyone would want to take their total meal cost and then multiply it by their tip to make it even larger. You would just add the tip to the meal cost.
The shortest distance from a point to a straight line is the
measurement of the line segment which connects the point to the straight line.
This line segment should be perpendicular to the line and is thus called the
perpendicular distance.
Answer:
Step-by-step explanation:
Total = 50
Males = 20
Females = 30
a) P(exactly 1 female) = P(1 female , 2 male)
(30C1 * 20C2) / (50C3) = 30*190/19,600 = 0.2908
b) P(at least 2 males) = 1 - (P(0 males) + P(1 males))
= 1 - 30C3 * 20C0/50C3 - 30C2 * 20C1/50C3
= 1 - 4060*1/19,600 - 435*20/19,600 = 6840/19600 = 0.3489
20% off means you paid only 80% of the original price.
0.8x=40
x=40÷0.8=50
so the original price is 50
