Answer:
m-45=-78
25=x+9
x and y are proportional, because they are doubling the outcome every time by 3, so the slope would simplify to 1/4 very time.
Step-by-step explanation:
Answer:
1) C. reject the null hypothesis; there is sufficient evidence to support the claim that “A” the students are NOT evenly distributed throughout the classroom
4) A. 7.815
7) D. fail to reject the null hypothesis; there is not sufficient evidence
i’m sorry my test doesn’t have questions 8 and 10 so i don’t know the answer
Step-by-step explanation:
i just took the test
Since we are going to check the similarity of the triangles and we have given two sides and angle we have to check the Side-Angle-Side option of the similarity. We have equal angles. Then, we have to check the proportionality of the sides. If these triangles are equal, then VT/QR=UT/RS. If we calculate it, 28/7=44/11=4. This last number is the similarity ratio and since we have proportionality, ΔQRS <span>~ </span>ΔVTU. The correct answer is D)

Answer: x = 90</h3>
============================================
Explanation:
The arc measure is some unknown number x, so is the angle formed by the tangents that form based on this arc. The arc and angle add to 180, so,
x+x = 180
2x = 180
2x/2 = 180/2
x = 90
A right angle forms if we were to draw segments from the center of the circle to the points of tangency. We have a square forming if we do so. Recall that the points of tangency have the radius and tangent segments meet up at a 90 degree angle.
