Answer:
Hope this helps! If I could have brainliest I'm trying to rank up.
Step-by-step explanation:
First find the probability of each color being drawn.
We need to find the total number of marbles first.
4 + 3 + 6 = 13
Everything will be over 13.
Probability of a white marble being drawn --> 4/13
Probability of a blue marble being drawn --> 3/13
Probability of a red marble being drawn --> 6/13
Now to find the probabilities of more than one being drawn, we can multiply.
Part A:
6/13*6/13=36/169
Part B:
3/13*3/13=9/169
Part C:
6/13*6/13=18/169
Part D:
7/13*7/13=49/169
Lets look at the hours they are open from. 9 am - 4:30 pm which is 7 and a half hours a day. Now we multiply 7 1/2 by the number of days they are open, which will be 7 1/2 * 255 = 1,912.5. This means that the library is open 1,912 1/2 hours a year.
I hope I've helped! :)
Answer:
32
Step-by-step explanation:
let a = 5
a² + 7 | Original equation
5² + 7 | Substitution of a as 5
25 + 7 | 5 to the power of 2 is 25, as 5*5 = 25.
32 | 25 + 7 = 32
Answer:
no it is not 32.725 is 0.01 less than
