When multiplying terms with the same base with exponents, you keep the base and add the exponents.
2^4 * 2^3 = 2^7
Any number with an exponent of zero equal one.
4^0 = 1
Multiply exponents when the term is being multiplied by a power.
(2^4)^3 = 2^12
When dividing terms with exponents, you keep the base and subtract the exponents.
9^7/9^5 = 9^2 9^5/9^7 = 1/9^2
5z - 8 = 32
5z = 32 + 8
5z = 40
z = 40/5
z = 8
So, your final answer is 8 which is option C.
Hope this helps!
Answer:
It's the second one
Step-by-step explanation:
If you use exponent rules (a*b)^n=a^n*b^n. Raise each term separately to 1/3 (by multiplying by 1/3) and then you get x^9 (y^1/3)
First arrange in ascending order of time:-
7, 8, 10, 12, 14, 15, 18, 20, 26, 30, 30, 30, 35, 35, 42, 55
MOde is the value occuring mos = 30.
Median is the mean of 2 middle numbers = (20 + 26) / 2 = 23
Mean = sum of the 16 numbers / 16 = 387/16 = 24.2
