Answer:
After 1.5 hours
Step-by-step explanation:
The truck and the car are moving in the same direction after they left the service station at the same time. The truck travels at 52 miles per hour and the car at 44 miles per hour.
Let us assume that after h hours their distance from each other will be 12 miles.
So, 52h - 44h = 12
⇒ 8h = 12
⇒ h = 1.5 hours.
Therefore, after 1.5 hours their distance from each other will be more than 12 miles and their radio contact will be lost after that. (Answer)
Answer:
The area of the picture is
Step-by-step explanation:
Let
x-----> the length side of the square picture
we know that
The area of the picture plus the frame minus the area of the picture is equal to the area of the frame alone
The area of the picture is
A= 3,3
B= -2,3
C=-1,-1
D=1,-3
Answer:
The 90% confidence interval for population mean length of eastern rods is (23.73, 24.07).
Step-by-step explanation:
The (1 - <em>α</em>)% confidence interval for population mean when the population standard deviation is not known is:
The information provided is:
Compute the 90% confidence interval for population mean length of eastern rods as follows:
Thus, the 90% confidence interval for population mean length of eastern rods is (23.73, 24.07).
The volume of the complex figure shown in the diagram is 56 m³.

Volume</h3>
Volume is the amount of space occupied by a three dimensional object.
Volume = length * breadth * width
The volume of the big cube = length * breadth * width = 7 * 3 * 4 = 84 m³
The volume of the small cube cut out = length * breadth * width = 4 * 7 * (4 - 3) = 28 m³
Volume of the complex figure = 84 m³ - 28 m³ = 56 m³
The volume of the complex figure shown in the diagram is 56 m³.
