Consider factors of 42, then if the factors can be added or subtracted.
42 = 42 * 1
42 = 21 * 2
42 = 14 * 3
42 = 7 * 6
Since none of these can be added or subtracted to equal 15, no intergers satisfy these criteria.
Answer:
0.50
Step-by-step explanation:
Let A represent the probability that it will be cloudy
Let B represent the probability that it will be rainy
P(A) = 0.40
P(B) = 0.30
P(A and B) = 0.20
For non mutually exclusive events the probability of event A or B is
P(A or B) = P(A) + P(B) - P(A and B)
= 0.40 + 0.30 - 0.20
= 0.50
There is a 50% probability that the picnic will be postponed. Therefore the probability that the picnic will not be postponed is equals 1 - P(A and B)
= 1 - 0.50
= 0.50 or 50%
Answer:
$0.40
Step-by-step explanation:
20 pounds = $8.00
1 pound = $8.00÷20
1 pound = $0.40
Earlier snow depth = 2 feet
later snow depth = 1.6 feet
change
2 - 1.6
0.4 feet
percentage change
(0.4 / 2) * 100
20 %
Answer:
The normal price of the drink is $1.2
Step-by-step explanation:
We are given the following in the question:
Number of drinks bought = 22
Discount on each drink = $0.35
Total money paid = $18.70
Let x be the normal price of the drink.
Thus, we can write the equation:
![\text{(Discounted price)(Total number of drinks)= Money paid}\\(x-0.35)(22) = 18.70\\22x - 7.7 = 18.70\\22x = 26.4\\x = 1.2](https://tex.z-dn.net/?f=%5Ctext%7B%28Discounted%20price%29%28Total%20number%20of%20drinks%29%3D%20Money%20paid%7D%5C%5C%28x-0.35%29%2822%29%20%3D%2018.70%5C%5C22x%20-%207.7%20%3D%2018.70%5C%5C22x%20%3D%2026.4%5C%5Cx%20%3D%201.2)
Thus, the normal price of the drink is $1.2
