Answer:
a) Therefore, exists 155 ways.
b) Therefore, exists 4845 ways.
c) That is not possible.
Step-by-step explanation:
We know that the math department of a college has 20 faculty members, of whom 5 are women and 15 are men. A curriculum committee of 4 faculty members is to be selected.
a) We calculate how many ways are there to select the committee that has more women than men
Therefore, exists 155 ways.
b) We get:
Therefore, exists 4845 ways.
c) That is not possible.
Answer:
Step-by-step explanation:
-18 = p / 2....multiply both sides by 2, cancelling out the 2 on the right side
-18 * 2 = p
- 36 = p <===
if it makes it easier to understand, p/2 is the same as (1/2)p
Answer:
83°
Step-by-step explanation:
A complementary angles' measurements will equal 90°. One of the angles = 7°. Subtract 7 from 90:
90 - 7 = 83
83° is the measurement of the complementary angle.

Answer:
D) 13
Step-by-step explanation:
Answer:
∠ 1 = 130°, ∠ 2 = 50°
Step-by-step explanation:
∠ 1 and 130° are alternate angles and congruent, so
∠ 1 = 130°
∠ 2 and 130° are same- side interior angles and are supplementary, so
∠ 2 + 130° = 180° ( subtract 130° from both sides )
∠ 2 = 50°
