Answer:
162 cents
Step-by-step explanation:
to find the rate you want take the inches which is 21 and divide by the cost which is 63 and find the rate is 3 which means each inch costs 3 cents and so with that rate you can find the cost of 54 inchest of wire so you take your 54 inches and multiply it by 3 which is the cents per inch and find that 54 inches of wire would cost you 162 cents
The different ways can a student check off one answer to each question is 1024.
It is required to find the different ways can a student check off one answer to each question.
<h3>What is probability?</h3>
probability is the ratio of the number of favorable outcomes and the total number of possible outcomes. The chance that a particular event (or set of events) will occur expressed on a linear scale from 0 (impossibility) to 1 (certainty), also expressed as a percentage between 0 and 100%.
Given:
If a multiple choice test consists of 5 questions each with 4 possible answers of which only one is correct,
,To find how many different ways can a student check off one answer to each question we have,
: 4^5 = 2^10
= 1024
Therefore, the different ways can a student check off one answer to each question is 1024.

first you need to find the slope (m) using y2-y1/x2-x1.
-4-2/4-1= -6/3=-2
m=-2
then plug into the intercept form formula: y-y1=m(x-x1)
y-2=-2(x-1)
You need to know:
Tangent function has range of <span>(-∞, ∞)
Sine function has range of [-1,1], which is the same as cosine function
So [-3,3] matches the 1st, [0,2] matches the 2nd, [-1,7] matches the 3rd, the 4th will be the rest </span>
