Answer:

(a) 110 mm Hg

(b) 70 mm Hg

(c) 3/4 second

(d) see the attachment

Step-by-step explanation:

(a) The sine function has a maximum value of +1, so the maximum value of p is ...

pmax = 20·(+1) +90 = 20+90 = 110 . . . . . mm Hg

__

(b) The sine function has a minimum value of -1, so the minimum value of p is ...

pmin = 20·(-1) +90 = -20+90 = 70 . . . . . mm Hg

__

(c) The period of the sine function is 2π, so the value of t that makes the argument be 2π will be the period.

8π/3·t = 2π

t = 2π·3/(8π) = 3/4 . . . . . . multiply by the inverse of the coefficient of t

The period of her heartbeat cycle is 3/4 seconds.

__

(d) a graph is attached.

Write the following expression as a fraction in lowest terms:

alukav5142 [94]

Step-by-step explanation:

$\[2 + \cfrac{2}{2 + \cfrac{3}{3 + \cfrac{4}{4 + 5}}}\]=$

$\[2 + \cfrac{2}{2 + \cfrac{3}{3 + \cfrac{4}{9}}}\]=$

$\[2 + \cfrac{2}{2 + \cfrac{3}{\cfrac{31}{9}}}\]=$

$\[2 + \cfrac{2}{2 + \cfrac{27}{31} }}}\]=$

$\[2 + \cfrac{2}{ \cfrac{62+27}{31} }}}\]=$

$\[2 + \cfrac{2}{ \cfrac{89}{31} }}}\]=$

$\[2 + \cfrac{62}{{89} }}}\]=$

$2 \cfrac{62}{{89} }}}$

Answer:

1980 total outcomes are possible.

Step-by-step explanation:

The order in which the candidates are chosen is not important. So we use the combinations formula to solve this question.

Combinations formula:

$C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

How many total outcomes are possible?

2 men, from a set of 11.

2 women, from a set of 9.

So

$T = C_{11,2}*C_{9,2} = \frac{11!}{2!9!}*\frac{9!}{2!7!} = 1980$

1980 total outcomes are possible.
