Answer:
1. SSS
2. Q and S
3. 20
Step-by-step explanation:
1. SSS similarity: If the corresponding sides of two triangles are proportional, then the two triangles are similar.
Triangles NLM and WUV are similar by SSS similarity, because

2. Completed steps:
a) draw a circle with center at P and radius r
b) draw a circle with center at Q and radius r
c) using compass, measure the distance between two points of intersection of the first circle with angle rays
d) using point of intersection of the second circle with PQ as a center, draw the circle of radius equal to the distance from c) to get point S
Last step: connect points Q and S, line QS will be parallel to line r.
3. If lines MN and UT are parallel, then angles MUT and VMN are congruent; also angles UTN and MNV are congruent.
AA similarity: In two triangles, if two pairs of corresponding angles are congruent, then the triangles are similar .
By AA similarity, triangles VMN and VUT are similar, thus

Answer:
-2
Step-by-step explanation:
Answer:
The correct null hypothesis in words is:
D. The long-run proportion of private colleges in the US, that have tenure-track faculty is 0.5.

Step-by-step explanation:
He wants to test the claim that the proportion of private schools that have avenues for professors to apply for tenure is significantly higher than 0.5, as happen with the public schools.
Then, the alternative hypothesis is:
The null hypothesis represents the opposite claim, where the proportion is not significantly higher than 0.5. Then, the null hypothesis is expressed as:

The correct null hypothesis in words is:
D. The long-run proportion of private colleges in the US, that have tenure-track faculty is 0.5.
This is about conversion of currencies.
<u><em>He spent £25 on the first day.</em></u>
- We are told he had spent £28 over 7 days.
Each day, he spends 50 pence more than the previous day. This means that;
1 pound = 100 pence
Thus, 50 pence = (50 × 1)/100 = £0.5
- If the money he spent on the first day is £x.
- On second day, he would have spent a total of; £(x + 0.5)
- On third day; x + 0.5 + 0.5= x + 1
- On fourth day; x + 1 + 0.5 = x + 1.5
- On fifth day; x + 1.5 + 0.5 = x + 2
- On sixth day; x + 2 + 0.5 = x + 2.5
- On seventh day; x + 2.5 + 0.5 = x + 3
x = 28 - 3
x = £25
