Option C: 1 is the simplification of the expression 
Explanation:
The given expression is 
We need to simplify the given expression.
<u>Simplification:</u>
To simplify the given expression, let us apply the exponent rule,
where 
Thus, the the exponent rule
means that any value (except zero) to the power of zero is equal to one.
Thus, the expression
becomes,

Therefore, the simplified expression is 1
Hence, Option C is the correct answer.
425/1700 = 0.25
Therefore he spends 25% of his income on rent
Answer:
P ( snowboard I ski) = 0.5714
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is

In which
P(B|A) is the probability of event B happening, given that A happened.
is the probability of both A and B happening.
P(A) is the probability of A happening.
In this question:
Event A: Ski
Event B: Snowboard.
28 out of 120 students ski:
This means that 
16 out of 120 do both:
This means that 
P ( snowboard I ski)

So
P ( snowboard I ski) = 0.5714
Answer:
y = -7x - 5
Step-by-step explanation:
y-intercept= 16 - (-7) (-3) = - 5
SO you need to divide 24 by 3 to know how many times she lost points. This would be eight times. And you know it is seven points for each time so then you multiply 8 by 7 and your answer will be 56 points.
