We try to represent the data in segments from 0 to 20.
<span>The length of the line segment along the number line from 0 to 5 is 5 - 0 = 5 units. The length of the line segment along the number line from 20 to 5 is 20 - 5 = 15 units. If you were to randomly throw a dart on this number line, then the probability of landing in the shaded region is 15/20 = 3/4 or 75%</span>
The first step to solving this is to use tan(t) =

to transform this expression.
cos(x) ×

Using cot(t) =

,, transform the expression again.
cos(x) ×

Next you need to write all numerators above the least common denominator (cos(x)sin(x)).
cos(x) ×

Using sin(t)² + cos(t)² = 1,, simplify the expression.
cos(x) ×

Reduce the expression with cos(x).

Lastly,, use

= csc(t) to transform the expression and find your final answer.
csc(x)
This means that the final answer to this expression is csc(x).
Let me know if you have any further questions.

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:
x = 54
y = 114
Step-by-step explanation:
y = 114 because of the Corresponding Angles Theorem:
"If two parallel lines are cut by a transversal, then the pairs of corresponding angles are congruent."
(x + 12) + y = 180
x + 12 + 114 = 180
x + (126 - 126) = (180 - 126)
x = 54
Quick Check:
54 + 12 + 114 = 180 ✔
