Answer:
a=5
b=15
Step-by-step explanation:
By following the pattern on the table we can see that the x is increasing by 1 and the y is increasing by 3 each time. Therefore, the next set of numbers would be (5,15).
D? Tell me if you got it right
Answer:
Step-by-step explanation:
Assuming this question : "A bottling plant fills one-gallon jugs with milk. The labels on the jugs state that the volume of milk they contain is 128 fluid ounces (fl. oz.). Federal law mandates that the jugs must contain no less than the stated volume. The actual volume of milk in the jugs is normally distributed with mean μ=129 fl. oz. and standard deviation σ=0.8 fl. oz. Plant workers take a simple random sample (SRS) of 8 jugs, measure the volume of milk in each jug, and calculate the sample mean".
Previous concepts
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".
Solution to the problem
Let X the random variable that represent the volume of milk in the jugs of a population, and for this case we know the distribution for X is given by:
Where and
Since the distribution for X is normal then the distribution for the sample mean is given by:
And the standard deviation for the sample mean would be given by:
Answer:
D). 2.4
Step-by-step explanation:
Mary is driving toward north so the angle is 90° and Danny is driving toward the east so angle is 0°
Momentum Dary=
Momentum Danny=
So the total momentum is the magnitude:

mag= ≅
Answer:
Option 3. 1,000 times
Step-by-step explanation:
we know that
The value of digit 8 in 82.77 is equal to 80
The value of digit 8 in 20.18 is 0.08
so
Divide 80 by 0.08
80/0.08=1,000 times
