Answer:
35 the missing # doesn't matter
Step-by-step explanation:
First, I will add up the know amount of points Chef Curry scored
45 + 48 + 32 + 40 = 165
To find the mean, add up all the numbers and divide that by how many values you had
I know 210 / 5 = 42, so I will subtract:
210 - 165 = 45
Cheer Curry scored 45 points

Answer:
1/12
Step-by-step explanation:
Probability of first marble being red is 2/9.
Then since he is not replacing the marble, there is only 8 marbles left in the bag. So the probability of choosing blue is 3/8. Then you multiply 2/9 × 3/8 = 6/72.
In simplest form: 1/12
Answer:
B) The earthquake measuring 4.5 on the Richter scale is about 32 times more intense than an earthquake measuring 3.
Step-by-step explanation:
Let Ra = log(Ia/Io), and Rb = log(Ib/Io). Then for ...
Ra - Rb = 4.5 -3.0 = 1.5
log(Ia/Io) -log(Ib/Io) = 1.5 . . . . . . . . . . . substitute the given expressions
(log(Ia) -log(Io)) -(log(Ib) -log(Io)) = 1.5 . . . expand the logs
log(Ia) -log(Ib) = 1.5 . . . . simplify
log(Ia/Ib) = 1.5 . . . . . . . . write as a single log
Ia/Ib = 10^1.5 ≈ 32 . . . . take the antilog
The ratio of intensities is about 32, corresponding to choice B.
