So the answer would be A. I had a bit of trouble figuring this out, but then I went to Order of Operations and found it out.
So you fill in n, and I just used 9 since it's in the question. So then, subtract 1 from 9, giving you 8. Then you multiply 0.35 by 8, giving you 2.8. Now lastly, add 7.51, and you get 10.31
I hope this helps you! If it does, please rate as Brainliest :D
Answer:
1)Take the smallest power common
2) simply the bracket
3) multiply with the power taken common
Example:
5×10⁶ - 4×10³
Smaller power is 3, so take 10³ common:
10³[(5×10²) - 4]
10³[500 - 4]
10³(496)
496×10³
4.96×10⁵
Step-by-step explanation:
x = 55

Answer: probability of Jake took 2 reds marbles = 3/52
probability of John took 1 blue marble = 1/8
Step-by-step explanation:
Okay, I will assume in this problem that the sample is not replacement, which means after Jake took 2 marbles, he didn't put it back into the sample.
The total of the sample = 20 + 10 +5 +5
Probability of Jake took the 1st red marble is 10/40 because there are 10 marbles in a whole bag of 40 marbles. Once Jack picked the 1st red marble out, there are only 9 red marbles left, thus the probability of the 2nd red marble is 9/39.
=> probability of Jake took 2 reds marbles = (10/40) *(9/39) = 3/52
and it goes the same way for John, except we only need to find 1 blue marble so we don't have to multiply anything here.
=> probability of John took 1 blue marble = 5/40 = 1/8
They answer is 4.75. 1/4 =.25 so 5-.25=4.75
