So let's convert these to improper fractions:
Then let's convert these fractions so that they have a denominator of 15 so we can better compare these numbers:
So when we have 
gallons splash out, we are left with 
gallons or 
gallons in the tub.
In this number 800 is 10 times as much as what number. To answer the query we can illustrate this problem into a mathematical equation of
1. 10 x N = 800
2. 10N = 800
3. N = 800/10
4. N = 80
the answer is 80.
Hope this helps!
Question:
If a sample of 2 hammer is selected
(a) find the probability that all in the sample are defective.
(b) find the probability that none in the sample are defective.
Answer:
a 
b 
Step-by-step explanation:
Given
--- hammers
--- selection
This will be treated as selection without replacement. So, 1 will be subtracted from subsequent probabilities
Solving (a): Probability that both selection are defective.
For two selections, the probability that all are defective is:
Solving (b): Probability that none are defective.
The probability that a selection is not defective is:
For two selections, the probability that all are not defective is:
( 6 − 7 i ) ( − 8 + 3 i )
First FOIL:
( 6 − 7 i ) ( − 8 + 3 i ) = -48 + 18i + 56i -21i^2
Combine like terms
= -48 + 74i -21i^2
Convert i^2 = -1
= -48 + 74i -21(-1)
And simplify
= -48 + 74i + 21
= -27 + 74i
Answer:
He isn't correct. He spent 25% more time this week than the previous one.
Step-by-step explanation:
We will make proportion.
first week 20 hours is 100%
second week 25 hours is x%
20 : 25 = 100 : x
When we multiply external and internal members we get:
20x =25 · 100 => x = 2500/20 = 125%
We conclude the following:
Evan spent 125% of the time in hours compared to the last week or Evan spent 25% more time this week than the previous one.
God with you!!!
