Answer:
25
Step-by-step explanation:
Given the indicinal equation
5^-1/5^-3
According to one of the law of indices, if a, b, m and n are integers then;
a^m/a^n = a^(m-n)
When the base are equal, the powers will be subtracted.
Applying this formula to the given expression
5^-1/5^-3
= 5^{-1-(-3)}
= 5^(-1+3)
= 5^2
= 25
Therefore the answer is 25
Answer The sample must represent the target population.
Step-by-step explanation:
Answer:
a. 18 dollars per hour
b. 16 dollars per hour
Step-by-step explanation:
for a, 18 is the slope of y=18x, meaning spongebob earns 18 dollars per hour
for b, since it seems like squidward earns 32 dollars every 2 hours, it can be guessed that he earns 16 dollars per hour, since 32/2 = 16
Answer:
Step-by-step explanation:
So, lets do the first one.
Slope = 0 and y-intercept is (0, -1)
The y intercept is the second number in the pair because it's the y value
we can switch this to,
y = mx + b
so,
y = 0x - 1
for the first one.
The second one has a slope of -1 and a y intercept of (0,4)
like I said the y intercept is the second number in the coordinate pair,
so,
y = -1x +4
Hope this helps!
The answer is 275 because when you multiply 11 by 25 you get 275
