Answer:
X +y=90 ( being complementary angles)
Answer:
A) <SQT = 36 degrees
B) <QRW = 36 degrees
C)<PRV = 72 degrees
Step-by-step explanation:
A) <SQT = 36 degrees (< SQT and < PQR are<em> vertically opposite angles</em>, and vertically opposite angles are equal)
B) <QRW = 36 degrees ( <QRW and < SQT are <em>corresponding angles</em> since they lie on the same side of the transversal across the parallel lines. Corresponding angles are equal)
C)<PRV = 72 degrees( <PRV is the <em>exterior base angle </em>to < PQR and exterior base angles, are always twice their interior correxpondents)
Answer:
0.731 < p < 0.775
Step-by-step explanation:
We have a sample proportion of 753/1000 = 0.753
We need to construct a 90% confidence interval for the population proportion. Since n > 30, we use the corresponding z-value of 1.645.
See attached photo for the formulas and construction of the confidence interval.

Answer:
7. 1/3
8. 1/6
9. 13/24
10. 5/8
11. 17/24
12. 0
Step-by-step explanation:
First find the total number balls by summing the indiviudal number of balls:
Total = 5 + 8 + 7 + 4 = 24
Then, the find any probability divide the number of ways your selected situation can happen from the total:
A final step if you want is to reduce the fraction to its simplest value. For example,
7) 8/24 = 1/3
8) 4/24 = 1/6
9) (8+5)/24 = 13/24
10) (24 - 5 -4)/24 = 15/24 = 5/8
11) (24 - 7)/24 = 17/24
12) (0)/24 = 0
