Answer:
x = 45
y = 37
z = 23
Step-by-step explanation:
x + y + z = 105
x = z + 22
x + 15 = y + z
(z + 22) + 15 = y + z
37 = y
x + y + z = 105
(z + 22) + 37 + z = 105
2z = 46
z = 23
x + y + z = 105
x + 37 + 23 = 105
x = 45
Answer:
100
Step-by-step explanation:
A dice has 6 sides and, theoretically, each side has the same probability of being rolled. So, if a dice was rolled a number of times, it would land on each side the same number of times. This means that 6 would be rolled 1/6 of the time. Since 1/6 of 600 is 100, that is how many times 6 would be rolled.

44478720=1/7 of the earths surface

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.
