Answer:Another variant of the important rule above is ax ay. = ax-y. And there is also the following slightly related rule. (ax)y = axy ... 10-3 = 1. 103 = 1. 1000. • 156. 155 = 156-5 = 151 = 15. • (25)2 = 210 = 1024. • (320). 1. 10 = 32 = 9. • 8-. 2 ... If f(x) is an exponential function whose base equals 1 – that is if f(x)=1x. – then for n, m ∈ N ...
Step-by-step explanation:
Answer: There would be 17 Left-handed students
Step-by-step explanation: I know there's a common core way to do this by doing cross multiplication with 1/5 x "x"/85 (x being the answer) but this question is simple enough to just divide 85 by 5
For the bottom part of 3) 2/5 times 2/2 would equal 4/10
Answer:
The answer to your question is 2.8 x 10¹¹
Step-by-step explanation:
Data
1 tree produces 2.6 x 10² pounds of oxygen/year
number of trees = 3.9 x 10¹¹
pounds of oxygen per day = ?
Process
1.- Divide the pounds of oxygen by 365, to get the pounds of oxygen per day.
2.6 x 10² / 365 = 0.712
2.- Multiply the number of trees by the pounds of oxygen per day
3.9 x 10¹¹ x 0.712 = 2.8 x 10¹¹ pounds of oxygen
Answer:
5/21.
Step-by-step explanation:
Total number of balls = 7.
Prob(Blue on first pick) = 3/7
Prob(Blue on second pick) = 2/6 = 1/3
So Prob( 2 Blue's) = 3/7 * 1/3 = 3/21 = 1/7.
Prob(Red on first pick) = 2/7
Prob(Red on second pick) = 1/6
So Prob( 2 Red's) = 2/7 * 1/6 = 1/21.
Now the Probability of getting 2 white balls is the same as for the red balls
= 1/21.
Finally, the probability of 2 balls of the same colour
= 1/7 + 1/21 + 1/21
= 3/21 + 1/21 + 1/21
= 5/21.
