Answer:
3.0
Step-by-step explanation:
n=10
p=0.30
mean=np=10X0.3 = 3
That is it.
Based on the calculations, the measures of angles 1 and 2 are 50° and 135° respectively.
<h3>What is the theorem of intersecting chord?</h3>
The theorem of intersecting chord states that when two (2) chords intersect inside a circle, the measure of the angle formed by these chords is equal to one-half (½) of the sum of the two (2) arcs it intercepts.
By applying the theorem of intersecting chord to circle U shown in the image attached below, we can infer and logically deduce that angle 1 will be given by this formula:
m∠1 = ½(53 + 47)
m∠1 = ½(100)
m∠1 = 50°.
Since angles 1 and 2 are linear pair, they are supplementary angles. Thus, we have:
m∠1 + m∠2 = 180°
m∠2 = 180 - m∠1
m∠2 = 180 - 50
m∠2 = 130°.

Answer:
<u>The correct answer is B. 9</u>
Step-by-step explanation:
Let's solve for y in the equation below, given that x = 2
y = 6x - 3
Substituting x in the equation, this way:
y = 6 * 2 - 3
y = 12 - 3
y = 9
The value of y is 9 when x is 2
<u>The correct answer is B. 9</u>
