Answer:
-62/23 degrees per hour
Step-by-step explanation:
Do this by dividing the total change in temperature (-15 1/2 degrees) by the total elapsed time (5 3/4 hrs):
-31/2 degrees -62/4 degrees Note: convert 31/2 to 62/4
--------------------- = ------------------------ = -62/23 degrees per hour
23/4 hrs 23/4 hrs
Answer:
197,250
Step-by-step explanation:
2.5 * 0.04 * 250 * 8 * 1.25 * 789
0.1 * 250 * 8 * 1.25 * 789
25 * 8 * 1.25 * 789
200 * 1.25 * 789
250 * 789
789/4 * 1000
197.25 * 1000
197,250
Answer: A
Step-by-step explanation: when Constructing a confidence interval, it is important to take note of the margin of error which is given by the formulae below
Margin of error = critical value × σ/√n.
Where n is the sample size.
As we can see that the critical value is a constant and the population standard deviation.
Hence there is an inverse relationship between margin of error and sample size, which implies that a large sample size produces a small margin of error.
If the margin of error is small, it means the sample size will increase the like hood that the sample is a good representation of the population.
Answer:
Step-by-step explanation:
10x + 8y = -18
-8x - 8y = 24
2x = 6
x = 3
8(3) + 8y = -24
24 + 8y = -24
8y = -48
y = -6
(3, -6)
