Answer is B cause you have to minus the 20 then then swap the signs
Answer:
a rate is a special type of ratio that compares 2 DIFFERENT quantities while a ratio is a comparison of 2 quantities BY DIVISION
a percentage is a rate, number, or amount in each hundred.
step-by-step explanation
u can see percentages in stores like 30% off. If the price of the product is $2.99 you have to multiply 2.99 by 30% equal 0.3, then do 2.99 - 0.3 = $2.69
a rate is this 200\5 = 40\1
a ratio is this <u>3 to 4 or 5 for every 3</u>

Answer:
$122.28
Step-by-step explanation:
Give the following :
Insurance worth = $240,000
Price sold = $225
P(survival) = 0.999572
P(death) = 1 - 0.999572 = 0.000428
If she survives, insurance firm makes $225
If she dies, insurance firm pays $240,000, hence the company losses :
$(225 - 240,000) = $−239775
Expected value (E(x)) = sum of P(i) * X(i)
E(x) = (P(survival) * profit made) + (P(death) * loss incurred)
E(x) = (225 * 0.999572) + (0.000428 * −239775)
= 224.9037 - 102.6237
=$ 122.28
Answer:
m = 3/2
Step-by-step explanation:
The slope of a line is m = rise / run.
As we move from P to Q, x increases from -8 to -5 (3 units) and y decreases from -10 to -12 (2 units). Hence, the slope of this line is m = rise / run
and m = -2 / 3.
Any line perpendicular to this line has a slope which is the negative reciprocal of this.
(slope of perpendicular line) = -1 / (-2/3) = 3/2
