So you need to decide if you are using cos,sin or tan

You use soh cah toa for this

You label the sides

Hypotenuse - which is the side opposite the right angle

Opposite- which is the side opposite the angle given

Adjacent - the left over side

In this case the opposite doesn’t have any values so we are going to cross it out

We are using CAH

Put this into your calculator : Cos(73)x6

Cos(73)x6 = 1.754230228

The answer is 1.8 to 1 decimal place

Alice, Bob and Kevin

7 different Flavors:

Chocolate

Vanillla

mint chip

strawberry

cookie dough

banana

caramel

The order of the 9 scoops does not matter.

_ _ _ _

a) How many ways can she choose her 9 scoops so she gets at least 1 scoop of each flavor?

Since there are 7 flavors, and she wants at least one of each then we have:

$C=\frac{9!}{7!2!}\text{ =3}6$

Alice has 36 possibilites of choosing

b) Bob

Since Bob can't eat too much he can't do no more than 4

$C\text{ =}\frac{9!}{4!5!}=126$

Bob has 126 possibilities of making his choice.

c) Kevin

3 scoups of banana or 3 scoups of strawberries.

Considering He wants 9 scoups.

$C=\frac{9!}{6!3!}=84$

Kevin has 84 possibilities for banana or strawberries

Fantom [35]

Answer:

$n_1+n_2-2$

Step-by-step explanation:

If we had 2 independent samples with population variances unknown and equal and we want to compare the population mean between the both groups, the test statistic will be:

$t=\frac{x_1-x_2}{\sqrt{s_p^2(\frac{1}{n_1}+\frac{1}{n_2}) } }$
