Answer:
You will use the z score to find this so need a z score chart.
Step-by-step explanation: Remember to take what you want (35 ounce) minus the mean( 29) then divide by the standard deviation(4). Then you look up this number on the z score chart to find your probability of less than 35 ounces. You could then do the same thing using 34 ounces since your final answer will be between these two numbers.
Answer:
18 weeks
Step-by-step explanation:
Create an equation where x is the number of weeks he works
60x - 220 will represent his profit, since he gets $60 a week but spent $220 in equipment.
Set this equal to 860, then solve for x, to find when he will earn $860
60x - 220 = 860
60x = 1080
x = 18
So, it will take him 18 weeks to earn $860
Answer:
1399 sq. feet
Step-by-step explanation:
Now, the data given is
height of front of apartment = 60 feet
Width of front of apartment = 25 feet
So total are of front of apartment is = Height x Width
= 60 x 25
= 1500 sq. yards
Now for door
Height = 7 feet
Width = 3 feet
So, total are of door
= Height x Width
= 7 x 3
= 21 sq. yards
Now for each window
Height = 4 feet
Width = 2 feet
So, total are of one window
= Height x Width
= 4 x 2
= 8 sq. yards
Now note that, for 10 windows area will be
= 8 x 10
= 80 sq. yards
Now understand that we have to find the area for bricks, but bricks will cover entire front except the door and windows. So, we have to subtract area of door and windows from total front area of apartment.
Area for bricks = Total front area - (area of door + area of 10 windows)
Area for bricks = 1500 - 21 - 80
Area for bricks = 1399 sq. yards
$ 14.97 is the answer
9.98 x 3 divide total by two
