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
Answer:
x<15
Step-by-step explanation:
-(x - 1) + 20 <-3(x - 3)
-x + 1 + 20 <-3x + 9
-x + 21 < -3 + 9
-x < -3 + 9 - 21
-x÷ -1 < -15 ÷ -1
x > 15

Anyway 4 % of 73 = 2.92
The following formula for compound interest applies:
where A is the amount after t years, P is the principal and r is the annual interest rate expressed as a decimal. Plugging the given values into the formula gives:
The amount after 4 years is therefore $2,431.01
Answer:
25%
Step-by-step explanation:
Assuming the catching of a fish is a random process and that the probability of catching any of the listed kinds of fish is proportional to their population, then the probability of catching a sturgeon is 50%. The probability of catching another one is also 50% (assuming the events are independent). So, the joint probability is the product of these:
0.50 × 0.50 = 0.25 = 25% . . . . . probability of catching 2 sturgeon in a row.
