The original price of a sweatshirt is $50. The sale price is 75% off the original price. Find the sale price of the sweatshirt.
Julli [10]

Answer:

$87.5

Step-by-step explanation:

Original price also means COST PRICE

C.P=$50

S.P=75% of $50-$50

To find the sale price it will be 75% of C.P -C.P

75% × $50 + $50= 0.75 × $50-$50

=$37.5-$50.

= $12.5

therefore the sale price is $12.5

14. A company uses many different delivery
ziro4ka [17]

Answer:

0.6603 = 66.03% probability that it will be sent with the ABC Speedy Delivery Company and arrive on time.

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

P(B|A) = \frac{P(A \cap B)}{P(A)}

In which

P(B|A) is the probability of event B happening, given that A happened.

P(A \cap B) is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Sent by ABC Speedy Delivery Service.

Event B: Arrived on time.

The probability that any given parcel will be sent by the ABC Speedy Delivery Service is 0.71.

This means that P(A) = 0.71

The probability that the parcel will arrive on time given the ABC Speedy Delivery Company was used is 0.93.

This means that P(B|A) = 0.93

Find the probability that it will be sent with the ABC Speedy Delivery Company and arrive on time.

This is P(A \cap B). So

P(B|A) = \frac{P(A \cap B)}{P(A)}

P(A \cap B) = P(B|A)*P(A) = 0.93*0.71 = 0.6603

0.6603 = 66.03% probability that it will be sent with the ABC Speedy Delivery Company and arrive on time.
