C because each adult and youth times the money amount would be the total. So for instance 74(2)+35(2)=218 bc that's the total. Hope I helped.
Three students want to estimate the mean backpack weight of their schoolmates. To do this, they each randomly chose 8 schoolmates and weighed their backpacks. Then as per the given sample data,
(a) The sample means of the backpacks are: 6.375,6.375,6.625
(b) Range of sample means: 0.25
(c)The true statement is: The closer the range of the sample means is to 0, the less confident they can be in their estimate.
For the first sample, mean= 6.375
For the second sample, mean= 6.375
For the third sample, mean= 6.625
Range of sample means=Maximum Mean- Minimum Mean
= 6.625 - 6.375
= 0.25
The students will estimate the average backpack weight of their classmates using sample means, the true statement is:
The closer the range of the sample means is to 0, the more confident they can be in their estimate.

Yes they are. Given that a volume of a rectangular prism is V=l•w•h, we can plug them into an equation and compare them. I'll call the Right rectangular prism figure R and the oblique rectangular prism O
For Figure R, We know all the basic needs to find the volume. This means we can plug it in.
V=l•w•h
V=12•3•5
Now We can solve for V
V=12•15
V=180
The volume of the right rectangular prism is 180in^3
Now, For figure O.
V=9•4•5
V=9•20
V= 180.
With this in mind, We now can say that the volumes of both the rectangular prisms are the same.
15.5 15.5 x 2 = 31. hope this helps
Tan T = UV/VT
UV = VT tan T = 40 tan 54
UV = 55.055 ft —> 55.1ft
