Answer:
(7^2)^2
7^2 / 7^-2
Step-by-step explanation:
7^-2 * 7^6
We know that a^b * a^c = a^ (b*c)
7^ (-2+6)
7^ 4
This is also 7^2 ^2
We also know that
7^2 / 7^-2
We know a^b / a^c = a^ (b-c)
7^(2 - -2) = 7^ (2+2) = 7^4
3/7. There are 7 temperatures, so the denominator is 7. However, only 3 of them were above 75, so the numerator is 3.
The first one
because like 13+52 = 63
Let say that you want to take 1 area. Before the event, the probability of A and B would be:
A= blue and green= (18/12x6) + (18/12x6) = 36/72
B= green and yellow= (18/12x6) + (18/12x6) <span>= 36/72
</span>
If the area that picked is green, then the probability of A and B become
A= blue and green= (18/12x6-1) + (17/12x6-1) = 35/71
B= green and yellow= (17/12x6-1) + (18/12x6-1) = 35/71
Both of the areas of A and B is decreased because they share the probability of green. So A and B would be a dependent event.
Hello, livelyemma4 happy Wednesday! It appears that this expression is not factorable with rational numbers. Sorry for any inconvenience this causes. Have a wonderful rest of your day.
