Answer:
Volume of the prism is 648
Step-by-step explanation:
Given:
Base of the prism is rectangular in shape
Height of the prism = 6 cm
Base length of the prism= 12 cm
Base width of the prism= 9 cm
To Find:
Volume of the prism=?
Solution:
Volume of the prism ,
V= Base area of the prism x Height of the prism
Here in the figure base of the prism is in Rectangular form
So the base area of the prism = area of the rectangle
We know that the area of the rectangle is = length x height
Substituting the values
Area of the Rectangle = 12 x 9
Area of the Rectangle = 108
So the are of the base of the prism is 108
Now
Volume of the prism,
V= 108 X 6
V= 648
For this case we have the following equation:
y = 14.25x
Where,
x: number of hours
y: total salary
For x = 175 we have:
y = 14.25 * (175)
y = 2493.75
The amount of money for unexpected expenses is:
unplanned expenses = 2493.75 - 1250 - 200 - 350 - 400 - 225 - 300
unplanned expenses = -231.25 <0
We note that there is no money left for unexpected expenses
Answer:
there is nothing left over
Answer:
d
Step-by-step explanation:
First compute the mean:
(4.67 + 4.98 + 4.34) / 3 = 4.66
then compute the variance:
(4.67-4.66)^2 = 0.0001
(4.98-4.66)^2 = 0.1024
(4.34-4.66)^2 = 0.1024
sum of the three = 0.2049
then take the square root:
= 0.452
the standard deviation is 0.452
