(7 1/2)/(1 1/2)=5
so there will be 5 shifts per hour.
1 decimeter is 10 centimeter so you divide 27 by 10 and get 2.7
So she cut 2.7 decimeter off her hair
Answer:
the one in the bottom is the graph in pretty sure
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.

Answer:
73 m is equal to 730 dm
Step-by-step explanation:
We Need to convert 73 m into dm
We know that 1 meter is equal to 10 decimeter
We are given 73 m. Multiply it with 10 and we will get value in decimeter
73*10
= 730 decimeter
So, 73 m is equal to 730 dm
