HELP!!!!! I do not understand how to do this! Could someone please explain to me how I would solve this problem?

What is the probability that a family with five children has all five girls?

harina [27]

Answer probability of one girl is 1 in 2 or 1/2 so multiply probability 5 times.

(1/2)(1/2)(1/2)(1/2)(1/2) = 1/32

There is a piece of tape attached to a hula hoop. The tape rotates to (_7, 20) during one spin. What is the sine value of this f

Shalnov [3]

Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions here.
Below are the choices that can be found from other source:

 −7
20
20 square root 449 over 449
negative 7 square root 449 over 449

The answer seems to be the third one which is 20 square root 449 over 449.

The manager of a snack bar buys bottled water in packs of 35 and candy bars in packs of 20. Then, she sells the items individual

Lerok [7]

$\Huge\bf{\underline{\red \dag { Aиѕωєя }}} \red \dag$

4 Packs of water and 7 Packs of candy bars.

So, we wanna know the smallest number that both 35 and 20 will go into.

Find the Least Common Multiple (LCM), but to find the LCM we need to find the prime factorization of each of the following number :-

$\sf {35 = 5(7)}$

$\sf \red {20 = 5(4)}$

$\sf {4 = 2(2)}$

$\sf \red {20 = 5(2)(2)$

~Now multiply all the numbers by 5 :-

$\sf \pink{5(7)(2)(2) = 35(2)(2) = 70(2) = 140}$

This means she needs 140 bottles of water and 140 candybars.

Water is sold in packs of 35, this means that she needs :

$\sf \orange{ \frac{140}{35} = 4\: packs \: of \: water}$

Candy bars are sold in packs of 20, this means she needs :

$\sf \green{ \frac{140}{20} = 7 \: packs \: of \: candy \: bars}$

2. Find the cosine function that is represented in the graph.

Diano4ka-milaya [45]

Answer:

$f(x) = cos(x - \frac{\pi }{4} ) -1$

Step-by-step explanation:

In this graph, we have the coordinate point ( $\frac{\pi }{4} , 0$ ). Without translations, cos(0) = 0, which means that the graph is shifted to the right by $\frac{\pi }{4}$ . We also know that the graph is shifted down by 1 because we have the point

( $\frac{5\pi }{4} , -2$ ), but accounting for the right shift, this point should really by ( $\pi , -2$ ). cos( $\pi$ ) = -1, but on the graph it is -2, meaning that it is shifted down by 1.

Therefore, accounting for the right shift by $\frac{\pi }{4}$ and the shift down by 1, our equation is $f(x) = cos(x - \frac{pi}{4} ) - 1$ .
