<h3>
Answer: B) Only the first equation is an identity</h3>
========================
I'm using x in place of theta. For each equation, I'm only altering the left hand side.
Part 1
cos(270+x) = sin(x)
cos(270)cos(x) - sin(270)sin(x) = sin(x)
0*cos(x) - (-1)*sin(x) = sin(x)
0 + sin(x) = sin(x)
sin(x) = sin(x) ... equation is true
Identity is confirmed
---------------------------------
Part 2
sin(270+x) = -sin(x)
sin(270)cos(x) + cos(270)sin(x) = -sin(x)
-1*cos(x) + 0*sin(x) = -sin(x)
-cos(x) = -sin(x)
We don't have an identity. If the right hand side was -cos(x), instead of -sin(x), then we would have an identity.
The dot-plot for the data is sketched at the end of this answer.
--------------------------
- The dot plot shows the <u>number of times each measure appears in the data-set.</u>
<u />
- 68 appears once, thus it is 1 in the dot-plot.
- 69 appears three times, thus it is 3 in the dot-plot.
- 70 appears once, thus it is 1 in the dot-plot.
- 71 does not appears, so it is 0.
- 72 appears once, thus it is 1 in the dot-plot.
- 73 appears five times, so it is 5 in the dot-plot.
- 74 appears once, thus it is 1 in the dot-plot.
- 75 does not appears, so it is 0.
- 76 appears twice, thus it is 2.
- 77 appears once, so it is 1.

Step-by-step explanation:
Answer:
42.2% of the applications came from small businesses
Step-by-step explanation:
the percentage of applications that came from small businesses can be calculated through:
percentage from small businesses = applications from small businesses / total number of applications = 30 / (23+18+30) = 0.422 (42.2%)
Lets organize out the numbers and calculate them,
so .....
Country music cd is $12
Rock music cd is 12× 2/3 = $8
Platinum edition cd is $8 x 2 = $16
add up all of the final numbers
<span>16+12+8 = $36
Your answer is
$36 </span>
