Answer:

1) 0.1504

2) 0.432

Step-by-step explanation:

1) The given information are;

The proportion of the morning appointments that are with elderly patients = 60%

The number of patients in the appointments  = 10 patients

The proportion of the morning appointments that are with non-elderly patients = 100 - 60 = 40%

The binomial probability distribution is given as follows;

P(X = r) = \dbinom{n}{r}p^{r}\left (1-p  \right )^{n-r}

P(X = 0) = \dbinom{10}{0}0.6^{0}\left (1-0.6  \right )^{10} = 0.000105

P(X = 1) = \dbinom{10}{1}0.6^{1}\left (1-0.6  \right )^{9} = 0.0016

P(X = 2) = \dbinom{10}{2}0.6^{2}\left (1-0.6  \right )^{8}= 0.01062

P(X = 3) = \dbinom{10}{3}0.6^{3}\left (1-0.6  \right )^{7}= 0.0425

The probability that the first four patients are elderly is 0.000105 + 0.0016 + 0.1062 + 0.0425 = 0.1504

2) The probability that exactly 2 out of 3 morning patients are elderly patient is given as follows

P(X = 2) = \dbinom{3}{2}0.6^{2}\left (1-0.6  \right )^{1}= 0.432

Find the value of x<br> (6x + 7)°<br> (8x - 17)°
Vlad [161]
<h3>Answer:  x = 12</h3>

Explanation:

The two angles shown are vertical angles. This occurs whenever you have an X shape like this, and whenever the angles are opposite one another. Vertical angles are always congruent.

6x+7 = 8x-17

6x-8x = -17-7

-2x = -24

x = -24/(-2)

x = 12
