Answer:
There are 108 inches in 9 feet
Step-by-step explanation:
Well, two unit multipliers mean we have to convert through two units before we arrive at our final answer so we can convert from feet to yards to inches!
We know that 3 feet equal a yard, right?
So we can divide 9 by 3 to get the amount that 9 feet translates to in yards.
So we are now done with our first conversion! Our second is going to be from yards to inches!
There are 36 inches in 1 yard so we should multiply 3 by 36 to get the amount in inches!

Answer:
(a-1) 22 rookies receiving a rating of 4 or better.
(a-2) 14 rookies received a rating of 2 or worse.
(b-1) Constructed below in explanation.
(b-2) 8% of total rookies received a rating of 5.
Step-by-step explanation:
We are provided the rating of Fifty pro-football rookies on a scale of 1 to 5 based on performance at a training camp as well as on past performance.
The frequency distribution constructed is given below:
Rating Frequency
1 4
2 10 where ranking of 1 indicate a poor prospect whereas
3 14 ranking of 5 indicate an excellent prospect.
4 18
5 4
(a-1) Rookies receiving a rating of 4 or better = Rating of 4 + Rating of 5
So, by seeing the frequency distribution 18 rookies received a rating of
4 and 4 rookies received a rating of 5.
Hence, Rookies receiving a rating of 4 or better = 18 + 4 = 22 rookies.
(a-2) Number of rookies received a rating of 2 or worse = Rating of 2 +
Rating of 1
So, by seeing the frequency distribution 10 rookies received a rating of
2 and 4 rookies received a rating of 1.
Hence, Rookies receiving a rating of 2 or worse = 10 + 4 = 14 rookies.
(b-1) Relative Frequency is calculated as = Each frequency value /
Total Frequency
Rating Frequency(f) Relative Frequency
1 4 4 / 50 = 0.08
2 10 10 / 50 = 0.2
3 14 14 / 50 = 0.28
4 18 18 / 50 = 0.36
5 <u> 4 </u> 4 / 50 = 0.08
<u>= 50 </u>
Hence, this is the required relative frequency distribution.
(b-2) To calculate what percent received a rating of 5 is given by equation :
<em> x% of 50 = 4 </em> {Here 4 because 4 rookies received rating of 5}
x = = 8% .
Therefore, 8% of total rookies received a rating of 5.
Answer:
Domain: {-3, 0 3}
Range: {0, 3}
Step-by-step explanation:
Recall that the Domain of a relationship associated with coordinate pairs of the form (x,y), is the set of all "x-values" given in the relationship.
The Range is the set of all "y-values" given in the relationship.
In our case, we have three coordinate points defining the relationship. These points have the following (x,y) coordinates (see attached image to see which coordinates are associated with each point):
(-3, 3), (0, 0), and (3, 3)
Therefore, the x values associated with these points are: -3, 0 and 3
therefore the Domain of the relationship is the set: { -3, 0, 3}
On the other hand, he y values associated with these points are: 3, 0, and again 3. So in fact there are just to distinct y-values: 0 and 3.
therefore the Range of the relationship is he set: {0, 3}
which corresponds to answer B.
