(b) There are 12 values in the data set which are greater than or equal to 30 and less than or equal to 39.

(c) There are 7 values in the data set which are greater than or equal to 40 and less than or equal to 49.

Step-by-step explanation:

We are given a set of data that is summarized by the stem and leaf plot below;

Steam Leaf

1  0 0 2 4 4 4 7 8 8 8 8 9

2  2 2 5 5 7 8

3  3 4 4 5 5 5 6 6 6 7 9 9

4  3 3 3 5 5 7 9

<u>This shows that the data values are:</u> 10, 10, 12, 14, 14, 14, 17, 18, 18, 18, 18, 19, 22, 22, 25, 25, 27, 28, 33, 34, 34, 35, 35, 35, 36, 36, 36, 37, 39, 39, 43, 43, 43, 45, 45, 47, 49.

(a) From the data above, the number of values in the data set which are greater than or equal to 10 and less than or equal to 19 is 12, i.e; 10, 10, 12, 14, 14, 14, 17, 18, 18, 18, 18, 19.

(b) From the data above, the number of values in the data set which are greater than or equal to 30 and less than or equal to 39 is 12, i.e; 33, 34, 34, 35, 35, 35, 36, 36, 36, 37, 39, 39.

(c) From the data above, the number of values in the data set which are greater than or equal to 40 and less than or equal to 49 is 7, i.e; 43, 43, 43, 45, 45, 47, 49.

A graphic artist receives a royalty payment of 5% for each game sold, and has an agent who gets 3% of what the graphic artist ge
Bumek [7]
The graphic artist receives 5% amount of the total sales as his royalty payment. The 3% from this royalty payment goes to his agent and remaining 97% are with the artist. So first we calculate the initial 5% amount the graphic artist will recieve, which will be:

0.05(2,000,000)= 100,000

$100,000 is the total royalty payment the graphic artist will receive. From this amount 3% goes to agent and 97% goes with artist. So the actual amount graphic artist will earn will be:

0.97(100,000) = 97,000

Thus, the graphic artist earns $97,000

Write the equation of a line parallel to the line:<br> y=-x-4<br> that goes through the point (-9,8)
Ymorist [56]

Answer:

y=-x-1 or, y-8=-1(x+9)

Step-by-step explanation:

Parallel lines have the same slope. in your current equation you have a slope of <u>-1</u>. We can use this slope and your set of points in the point slope formula.

<u>y-y1=m(x-x1)</u>

(-9, 8)

x1 y1 m=-1

<u>y-8=-1(x+9)</u>

y-8=-1x-9

+8 +8

<u>y=-x-1</u>
