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

Answer:

Angle A is 46. Angle B is 134

Step-by-step explanation:

If two angles are supplementary, they equal 180 degrees. So in order to find the measure of each angle, you need to find out what x is, by setting both equations equal to 180.

So it would look a little like this:

6x-8+9x+53=180.

Group like terms together

15x+45=180

get x alone by subtracting 45 on both sides

15x=135

and divide by 15 on both sides

x=9

So now we figured out that x = 9. Now plug that number in for both equations to find the angles of both

6(9)-8

54-8

angle A is 46

9(9)+53

81+53

angle B is 134

And you can check your work by seeing if both angles actually add up to 180, by definition being supplementary

134+46.. is 180

So there you have it

Answer:

A. 1/5k - 2/3j and -2/3j +1/5k

Step-by-step explanation:

A. 1/5k - 2/3j and -2/3j +1/5k

B. 1/5k - 2/3j and -1/5k +2/3j

There is a change in the signs of each term

1/5k changed to -1/5k

-2/3j changed to +2/3j

Not equivalent

C. 1/5k - 2/3j and 1/5j - 2/3k

There is a change in the variables

1/5k changed to 1/5j

-2/3j changed to -2/3k

D. 1/5k - 2/3j and 2/3j - 1/5k

The is a change in the signs of each term

1/5k changed to -1/5k

-2/3j changed to +2/3j

The only equivalent expression is

A. 1/5k - 2/3j and -2/3j +1/5k
