Answer:
C
Step-by-step explanation:
Using the trigonometric identity
csc x = 
Given
sinΘ = - 0.4, then
cscΘ =
= - 2.5 → C
Since the p-value of the test is of 0.00001 < 0.01, these results have statistical significance.
<h3>What is the relation between the p-value and the conclusion of the test hypothesis?</h3>
Depends on if the p-value is less or more than the significance level:
- If it is more, the null hypothesis is not rejected, which means that the results do not have statistical significance.
- If it is less, it is rejected, which means that the results have statistical significance.
In this problem, the probability is the p-value, hence since the p-value of the test is of 0.00001 < 0.01, these results have statistical significance.

On the number line you either start at -3 or -5 and you got your answer
Given:
Consider the below figure attached with this question.
In circle A below, chord BC and diameter DAE intersect at F.
The arc CD = 46° and arc BE = 78°.
To find:
The measure of angle BFE.
Solution:
According to intersecting chords theorem, if two chords intersect inside the circle then the angle on the intersection is the average of intercepted arcs.
Using intersecting chords theorem, we get




Therefore, the measure of angle BFE is 62°.
Answer:
36 years old
Step-by-step explanation:
let x = age of Rachael
2x+3 = current ages combined
[(2x+3)+4]+4 = 75
2x+11 = 75
2x = 75-11
2x = 64
x = 32
Rachel is 32 years old. Isaac is 3 years older, which is 35 years old.
