2. In a recent survey conducted by the International Nanny Association, 4,176 nannies were placed in a job in a given year. Only

24 of the nannies placed were men. Find the probability that a randomly selected nanny who was placed during the last year is a male nanny (a "mannie").

Answer:

There is a 0.57% probability that a randomly selected nanny who was placed during the last year is a male nanny (a "mannie").

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

In this problem, we have that:

Desired outcomes:

The number of male nannies selected. 24 of the nannies placed were men. So the number of desired outcomes is 24.

Total outcomes:

The number of nannies selected. 4,176 nannies were placed in a job in a given year. So the number of total outcomes 4176.

Find the probability that a randomly selected nanny who was placed during the last year is a male nanny (a "mannie").

P = \frac{24}{4176} = 0.0057

There is a 0.57% probability that a randomly selected nanny who was placed during the last year is a male nanny (a "mannie").

Four families went out for lunch. The total food
dybincka [34]

Answer:

Each family spent about 34.25 on dinner

Step-by-step explanation:

$167 - $30 (tip) = 137

137 ÷  4 (for each family) = 34.25

BUT

if each family is seperate than they each spent about 11.75 on dinner

167 - (30 x 4) = 47

47 ÷  4 = 11.75

I'm pretty sure the first one is the answer though

Find the length of each arc<br> r=13 ft x=90 degrees
VladimirAG [237]

Answer:

13\pi/2

Step-by-step explanation:

The formula of the circumference of a circle is 2\pi r.

The length of an arch can be found by using the ratio of circumference to the arc.

First, find the circumference of the circle:

2\pi *13=26\pi

Then you find the ratio:

The length of the arc is 90/360, which is 1/4, of the circumference.

Finally, find the length of the arc:

26\pi*1/4=(13/2)\pi or 13\pi/2

I hope this helps :)

Which best describes the graphs of the line that passes through (−12, 15) and (4, −5), and the line that passes through (−8, −9)
konstantin123 [22]

Answer:

C) They are perpendicular lines.

Step-by-step explanation:

We first need to find the slope of the graph of the lines passing through these points using:

m =  \frac{y_2-y_1}{x_2-x_1}

The slope of the line that passes through (−12, 15) and (4, −5) is

m_{1} =  \frac{ - 5 - 15}{4 -  - 12}

m_{1} =  \frac{ - 20}{16}  =  -  \frac{5}{4}

The slope of the line going through (−8, −9) and (16, 21) is

m_{2} =  \frac{21 -  - 9}{16 -  - 8}

m_{2} =  \frac{21  + 9}{16  + 8}

m_{2} =  \frac{30}{24}  =  \frac{5}{4}

The product of the two slopes is

m_{1} \times m_{2} =  -  \frac{4}{5}  \times  \frac{5}{4}  =  - 1

Since

m_{1} \times m_{2} =  - 1

the two lines are perpendicular.
