The angle is going to be less 90
The value of the mean is 3 for normal curve C and the value of the mean is 4 for the normal curve D, and for both data standard deviation is the same.
<h3>What is a normal distribution?</h3>
It's the probability curve of a continuous distribution that's most likely symmetric around the mean. On the Z curve, at Z=0, the chance is 50-50. A bell-shaped curve is another name for it.
We have a normal distribution curve shown in the picture.
For the normal curve C:
The value of mean = 3 (draw a vertical line in the middle of the curve)
For the normal curve D:
The value of mean = 4 (draw a vertical line in the middle of the curve)
For both data standard deviation is the same.
Thus, the value of the mean is 3 for normal curve C and the value of the mean is 4 for the normal curve D, and for both data standard deviation is the same.

Answer:
4534
Step-by-step explanation:wedfthbbbbbbbbbbbbbbbbbbbhhhhhhhhhhghhhgg
Plan A = 9 +0.17x
Plan B = 21 +0.12x
9+0.17x = 21+0.12x
X=240
9+0.17(240)=49.8
21+0.12 (240)=49.8
240 minutes and cost $49.80 each
Answer:
103.5%
Step-by-step explanation:
To find the percent change you will need to divide 621 by 600.
621/600 = 1.035
Multiply 1.035 by 100 to find the percent
(1.035)(100) = 103.5
Therefore, the value increased by 103.5%.
