Use the circle shown to answer the question.
1 answer:
The value of x in the angle ABC is 25.
<h3>How to find the angles in circle?</h3>The measure of an inscribed angle is half the measure of the arc intercept.
In other words, the measure of an inscribed angle in a circle equals half the measure of its intercepted arc.
Hence, lets find the value of x in the angle ABC.
Therefore,
m∠ABC = 1 / 2 (arc AC)
arc AC = 76 degrees.
Hence,
m∠ABC = 1 / 2 × 76
2x - 12 = 1 / 2 × 76
2x - 12 = 38
add 12 to both sides of the equation
2x - 12 = 38
2x - 12 + 12 = 38 + 12
2x = 50
divide both sides by 2
2x / 2 = 50 / 2
x = 25

Answer:
It is not normally distributed as it has it main concentration in only one side.
Step-by-step explanation:
So, we are given that the class width is equal to 0.2. Thus we will have that the first class is 0.00 - 0.20, second class is 0.20 - 0.40 and so on(that is 0.2 difference).
So, let us begin the groupings into their different classes, shall we?
Data given:
0.31 0.31 0 0 0 0.19 0.19 0 0.150.15 0 0.01 0.01 0.19 0.19 0.53 0.53 0 0.
(1). 0.00 - 0.20: there are 15 values that falls into this category. That is 0 0 0 0.19 0.19 0 0.15 0.15 0 0.01 0.01 0.19 0.19 0 0.
(2). 0.20 - 0.40: there are 2 values that falls into this category. That is 0.31 0.31
(3). 0.4 - 0.6 : there are 2 values that falls into this category.
(4). 0.6 - 0.8: there 0 values that falls into this category. That is 0.53 0.53.
Class interval frequency.
0.00 - 0.20. 15.
0.20 - 0.40. 2.
0.4 - 0.6. 2.
