Answer:
Probability = 1 / 5
Step-by-step explanation:
Assuming that rates are from 1 to 5 ; with equal probability of being 1, 2 , 3 , 4, 5 each.
So, probability of 3 stars = Outcomes with 3 stars / Total outcomes
= 1 / 5
Answer: 40 pages in total
Step-by-step explanation:
Ms. Vega has read 20% of the book and this translates to 8 pages of the book.
20% = 8 pages
Assume the total number of pages is x:
20% * x = 8
0.2x = 8
x = 8 / 0.2
x = 40 pages in total
Answer:
tanQ = 
Step-by-step explanation:
Since the hypotenuse is not known this rules out sine and cosine ratios.
tanQ = 
=
Answer:
- B. Quadrilateral PQRS is a trapezoid, because there is one pair of equal slopes, and thus one pair of parallel sides.
Step-by-step explanation:
<u>Given:</u>
- The slopes of the sides of quadrilateral PQRS are −23, 78, −23, and 1112.
As we see two of the slopes are same, indicating a pair of parallel sides.
The other two slopes are different, so there is only one pair of parallel sides.
This is a definition of a trapezoid.
Correct choice is B
