Answer:
Standard error of mean = 689
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = $28,520
Standard Deviation, σ = $5600
Mean of sampling distribution =
As per Central Limit Theorem, if the sample size is large enough, then the sampling distribution of the sample means follow approximately a normal distribution.
Sample size, n = 66
Since the sample size is large, we can use normal distribution for approximation.
Standard error of mean =
A=10ft because A is 8ft so round that to the nearest ten your answer is 10ft
The answer is 7i because if you add 4+3i together as an absolute value, it equals to 7 plus the i is 7i
Based on the information given the chocolates stated on the label is 0.0042-ounce lighter.
Weight:
Using this formula
Chocolate weight=Current weight-Actual weight
Where:
Current weight=0.384
Actual weight=0.3798
Let plug in the formula
Chocolate weight=0.384-0.3798
Chocolate weight=0.0042 ounce
In conclusion, the chocolates stated on the label are 0.0042-ounce lighter.
Answer:
y= -4x-9
Step-by-step explanation:
first you distribute the -4: y+5= -4x-4
then you subtract 5 from both sides to isolate the variable but keep the equation balanced: y= -4x-9
