Answer:

A. 15 c squared Start Root 3 End Root

Step-by-step explanation:

3\sqrt{5c} *\sqrt{15c^3} \\

Multiply the terms inside the square roots together

3\sqrt{75c^4}

Look for items that are perfects squares

3\sqrt{25*3*c^4}

We can separate terms inside the square root into separate square roots

3\sqrt{25} *\sqrt{3}*\sqrt{c^4}

3*5 *\sqrt{3} *c^2

Combine like terms

15c^2\sqrt{3}

In a recent​ poll, 44​% of survey respondents said​ that, if they only had one​ child, they would prefer the child to be a boy.
viva [34]

Answer:

a) The probability that 71 of 150 will prefer boy child is 71/150 or 0.47

b) The result contradicts the poll actual percentage is 47.33% which is 3.33% more than the poll predicted

Step-by-step explanation:

If 71 out of 150 prefer boy child

The probability that the 71 will prefer boy child is

= 71/150

The actual percentage is

(71/150)*100%

= 47.33%

This contradicts the poll as this is more than the poll predicted. That means Less than 71 of 150 actually preferred boy child.

Use the law of cosines to find the length of a
borishaifa [10]

Answer:

Step-by-step explanation:

You don't need the Law of Cosines, the Law of sines if what you need. You can't use the Law of Cosines because in order to find side a, you would need the length of side c and you don't have it. Using the Law of Sines is appropriate, knowing that angle B = 55:

\frac{sin55}{175}=\frac{sin42}{a} and solving for a:

a=\frac{175sin42}{sin55} so

a = 143.0
