-21.8+18.3
or 18.3-21.8
or the answer which is -3.5
Suppose you have a Kohls coupon of $49000 and you want to know how much you will save for an item if the discount is 60 percent.
Solution:
Replacing the given values in formula (a) we have:
Amount Saved = Original Price x Discount in Percent / 100. So,
Amount Saved = 49000 x 60 / 100
Amount Saved = 2940000 / 100
Amount Saved = $29400 (answer).
In other words, a 60% discount for a item with original price of $49000 is equal to $29400 (Amount Saved).
Note that to find the amount saved, just multiply it by the percentage and divide by 100.
Answer:
probability that his sample will contain at least one damaged apple (P) = 0.7215
Step-by-step explanation:
Given:
Probability of damaged apples (p) = 12% = 0.12
number of samples (n) = 10
Consider,
x- number of apples damaged.
Using Binomial distribution formula:
P(x) = 
To find the probability that his sample will contain at least one damaged apple:
P(x≥1) = 1 - P(x<1)
= 1 - P(x=0)
= 1 - 
P(x≥1) = 0.7215
Answer:
(21 + 11)2 = 64
So, I don't think teachers do this, but this is my way of doing it
Okay, so first, I divided 64 by 2 :
64 ÷ 2 = 32
Then, I subtracted 11 from 32:
21
Now, to check, just do the problem :
(21 + 11)2 = 64
32 * 2 = 64
