Greeley [361]

Since each table had 7 women and 3 men at each table, that would mean each table has 10 people. Since there are 9 tables he was waiting on, and 10 people at each table, multiply 9 x 10, and you will find that he served 90 people in total.

She wishes to estimate the proportion of horses with enteroliths who are fed at least two flakes of alfalfa per day. In a sample

pogonyaev

Answer:

0.0594.

Step-by-step explanation:

The standard error of a proportion p, in a sample of size n, is given by:

$SE_{p} = \sqrt{\frac{p(1-p)}{n}}$

In a sample of 62 horses with enteroliths, she finds 42 are fed two or more flakes of alfalfa.

This means that $n = 62, p = \frac{42}{62} = 0.6774$

$SE_{p} = \sqrt{\frac{p(1-p)}{n}}$

$SE_{p} = \sqrt{\frac{0.6774*0.3226}{62}} = 0.0594$

So the correct answer is:

0.0594.

In △ABD, altitude AC¯¯¯¯¯ intersects the right angle of triangle ABD at vertex A. BC=3.1 in. and CD=7.2 in..

vodomira [7]

Answer:

4.72 in.

Step-by-step explanation:

BC = 3.1 in.

CD = 7.2 in.

Altitude of right triangle altitude is given as $h = \sqrt{xy}$ , where:

h = altitude

x = 3.1 in.

y = 7.2 in.

Plug in the values into the formula

$h = \sqrt{3.1*7.2}$

$h = \sqrt{22.32}$

$h = 4.72 in.$ (nearest hundred)
