Hi there!
To calculate a discount or a mark-up in the price of a retail item, you need to multiply the given price of the item by the percentage, like so:
1.35 × 0.2 = 0.27
Then you add or subtract as necessary. In your case you would subtract since you are trying to find a discount price.
1.35 - 0.27 = 1.08
So the final price of the product after the discount is $1.08

Answer:
The required probability is 0.94
Step-by-step explanation:
Consider the provided information.
There are 400 refrigerators, of which 40 have defective compressors.
Therefore N = 400 and X = 40
The probability of defective compressors is:

It is given that If X is the number among 15 randomly selected refrigerators that have defective compressors,
That means n=15
Apply the probability density function.

We need to find P(X ≤ 3)


Hence, the required probability is 0.94

Answer:
15/31
Step-by-step explanation:
substitute -9 were there's x in the function
f(-9)=2(-9)+3/4(-9)+5
=-18+3/-36+5
=-15/-31
the negatives cancel giving you
