Ok so lets work it out ( answer at the bottom in bold) 

11:30 - 8 :15 = 3:15 ( 3 hours and 1 5 minutes) 
and for the next part its a little trickky cause we are going from am to pm but we can work it out
so we know it will end in 45 because it takes 30 + 30 = 1 hour and it says 4: 15 so we know we need a 15 and 15 + 30= 45 
so now we will put 45 to the side but we now instead of having 12:30 we have 1 :00 pm and 4:00 pm
4:00 - 1 : 00 = 3 pm and now we take the 45 and add it to the 3:00 pm so 3:00 + 45 = 3:45 pm
and now we add our 2 end results 
3 :45  + 3:15 = 7 hours
The nurse worked 7 hours

Find the midpoint given the endpoints (4,-10) (22,-4) Please do not use space when
Elza [17]

Answer: (13,-7)

Step-by-step explanation:

By using the formula (x_{m},y_{m})  =(\frac{x_{1}+x_{2}  }{2},\frac{y_{1}+y_{2}  }{2} )

(x_{m},y_{m})\\ is the coordinates of the midpoint.

For finding the midpoint X variable do:

(\frac{4+22}{2})=13

For finding the midpoint Y variable do:

\frac{-10+(-4)}{2} = -7 (you can either keep the parenthesis or take them out. Either way, the answer is the same.

Considering coordinate numbers follow the format: (x,y), you'll simply just substitute the numbers found above into their respective places.

x: 13

y: -7

(13,-7).

Last year a banquet hall charged $65 per person to attend a function. The function C(p) = 65p represents the total cost, C, to r
zlopas [31]

Answer:

Domain = [0, 50]

Range   = [0, 3250]

Step-by-step explanation:

A function shows the relationship between two variables (independent variable and dependent variable). The independent variable is a variable not dependent on any variable, it is the input of the function while the dependent variable is a variable dependent on other variable, it is the output of the function.

The domain of a function is the set of all input variables (independent variable) and the range of a function is the set of all output variables (dependent variables).

In the function C(p) = 65p, p is the independent variable and C(p) is the dependent variable.

Since the hall can hold a total of 50 people, the domain of the function = [0, 50]

C(0) = 65(0) = 0, C(50) = 65(50) = 3250

Hence, the range of the function = [0, 3250]

kotegsom [21]

Answer:

7

Step-by-step explanation:

f(x) means y, it is equal to the value of y, so f(x) = y

so, f(1) means to find the value of y when the value of x is 1, and that is 7, since 7 is the value of y indicated when the value of x is 1.

I hope this is helpful.

From the box plot:

median=46

Q1=42

Q3=70

Q3-Q1= IQR=70-42=28

max=76

min=34

Range=max-min=76-34=42
