Answer:
0.0043 is the probability that the sample of 20 bottles have a mean below 19.90 fl oz.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 20 fl oz
Standard Deviation, σ = 0.17 fl oz
We are given that the distribution of amount of soft drink poured is a bell shaped distribution that is a normal distribution.
Sample size, n = 20
Formula:
a) P(Sample of 20 bottles have a mean below 19.90 fl oz)
P(x < 19.90)
Calculation the value from standard normal z table, we have,
0.0043 is the probability that the sample of 20 bottles have a mean below 19.90 fl oz.
Answer:
All are correct.
Step-by-step explanation:
Let x be the number of movies and y be the number of newly released video games.
Larry has a gift card worth 400 for a local entertainment store Movies cost $20 each and newly released video games cost $50 each.
Larry must purchase at least nine items.
Check both inequalities of all given ordered pairs.
For (5,6),
Point (5,6) satisfy both inequalities.
For (10,4),
Point (10,4) satisfy both inequalities.
For (20,0),
Point (20,0) satisfy both inequalities.
For (15,2),
Point (15,2) satisfy both inequalities.
Therefore, all combination of movies and newly released video games Larry could purchase using his gift card.
Answer:
6000
Step-by-step explanation:
5,766
you look at the thousands place which is 5. We want to round that so look at the next place value which is 7. That is greater then the general number 5. So we round up to 6000.
Answer:
Equation of the axis of symmetry is: x = 3
Step-by-step explanation:
The equation
is the equation of a parabola, of the form
whose vertex is located at the x-coordinate:
Then, for our case the x position of the given parabola, is:
Then the equation of the axis of symmetry, which is a vertical line that goes through the vertex, would be given by:
x = 3
