Answer:

CD = 4

Step-by-step explanation:

I believe you know the geometric mean for altitudes?

CD = √AD * DB = √8 * 2 = √16 = 4

If you are not aware of this theorem, then use the similarity of triangles.

ADC ~ CDB

AD/DC = CD/DB (cross-multiply)

CD^2 = AD*DB,

CD = √AD * DB = √8 * 2 = √16 = 4

Given a group of 8 women and 11 men, how many different ways are there of choosing one man and one woman for a committee?
Mashutka [201]
Any of the 11 man can be chosen, and combined with any of the 8 women.

Assume we select man1. The selected committee can be:

(m1,w1), (m1,w2), (m1,w3), (m1,w4), (m1,w5), (m1,w6), (m1,w7), (m1,w8), 

so there are 8 committees selections with man1 in them.

we could repeat the same procedure for the remaining 10 men, and get 8 committees where each of them is a member.

so there are 11*8=88 ways of choosing 1 man and 1 woman.

A professor believes that students who smoke cigarettes tend to have lower grades. He collects data from 1326 randomly selected
andrew11 [14]

Answer:

No.

Step-by-step explanation:

His finding that "students who smoke cigarettes do indeed tend to have lower grade point averages than students who do not smoke" implies that there can be a connection between smoking and grades. It does not specifically refer to a causal relation that smoking causes lower grades. People who make bad decisions may choose not to study well and may choose to smoke.
