Prrime factors of 2015 are the number that mltiply to get it exg
prime factors of 100 are 2,2,5,5 becase if you multiply them together you get 100
so prime factors of 2015=5,13,31
then the sum is add ing them togherther
5+13+31=49
a
answer is 49
Answer:
Gianna makes $18 per hour.
Step-by-step explanation:
Given Gianna makes 90$ for 5 hours. That means she should make $ = 18$ every hour.
Therefore we have:
a.
HOURS DOLLARS
1 18
2 36
3 54
4 72
5 90
6 108
7 126
b.
For the tabular column mark Hours on the x - axis and Dollars on the Y - axis. It can be plotted from the above table easily.
c.
If Gianna works for 8 hours she would have made 8 X 18 = 144$.
So, she will earn 144$ in 8 hours.
d.
To make 60$ she would have to work hours = 3.33 hours.
The probability that the sum is strictly larger than 21 is P = 0.46
<h3>
How to find the probability?</h3>
We already have a 10 and a 4, so: 10 + 4 = 14
To sum more than 21, we need to draw at least an 8.
On the deck there are:
- 6 cards equal or larger than 8 of diamonds.
- 6 cards equal or larger than 8 of clubs.
- 6 cards equal or larger than 8 of spades
- 5 cards equal or larger than 8 of hearts (because we already drew the 10).
So, 23 out of 50 cards meet our requirements. So the probability will be:
P = 23/50 = 0.46
