Answer:
A. y = 2/5x - 2
Step-by-step explanation:
We can use the slope formula to find the slope of the line.
[tex]m=\frac{y_1-y_2}{x_1-x_2} \\m=\frac{-2-0}{0-5} \\m=\frac{-2}{-5}\\m=\frac{2}{5}[/tex]
Now we know that the slope of the line is 2/5. By looking at the graph, the line crosses the y-axis at the point (0, -2). Therefore, the equation of the line is y = 2/5x - 2.

This is a right triangle trig problem. The base of the right triangle is the distance that Donna if from the flagpole; the flagpole is the side opposite the reference angle which was given as 26, and we are looking for the height of the flagpole, h. The trig ratio that uses the side opposite over the side adjacent is the tangent ratio, specifically:
[tex]tan26=\frac{h}{123}[/tex] and
123tan(26) = h so
h = 60.0 rounded to the nearest tenth. But that is only the height from her line of vision and up, not the whole height. In order to find the whole height, we have to add in her height up to her line of vision which is 5.3 feet. Therefore, the height of the flagpole is
60.0 + 5.3 = 65.3 feet.

A bag contains five blue marbles, five red marbles, five white marbles, and five black marbles. You draw a marble from the bag, and then draw another marble from the bag.
Do you have a greater probability of drawing two blue marbles if you replace the first marble after you draw it or if you don't replace the marble?
Your answer should include both the mathematical proof and a written statement.
Answer:
If you replace the first marble, you have a higher chance of picking two blue marbles. Mathematical proof and written statement is shown below.
Step-by-step explanation:
Mathematical Proof :
For proof, we should test it out.
To find the total amount of marbles, we add up all the different colors in the bag.
5 + 5 + 5 + 5 = 20
Drawing 2 blue marbles while replacing the first probability :
The probability of drawing a blue marble at first is 5/20. If you then replace this marble, the probability doesn't change, it's still 5/20. To get the probability of getting two blue marbles and not replacing we multiply :
5/20 * 5/20 = 25/400 = 1/16
Drawing 2 blue marbles while NOT replacing the first probability :
The probability of first choosing a blue marble is 5/20, but you don't replace it, so now the probability of choosing a blue marble is 4/19, since one blue marble was taken. To find the probability of drawing two blue marbles but not replacing the first one we are going to have to multiply 5/20 * 4/19. That's 1/19.
So the probability of getting two blue marbles and replacing the first is 1/16, and the probability of getting two blue marbles and not replacing the first is 1/19. Well, which is greater? 1/16 is greater. If you replace the first marble, you have a higher chance of picking two blue marbles.
Written Statement :
If you replace the first marble you have a higher chance of getting two blue because you are increasing the number of blue marbles in the 20 total marbles. Now there is a greater number of blue marbles there is a greater chance you will pick blue.

A survey conducted by the American Automobile Association (AAA) showed that a family of four spends an average of per day while on vacation. Suppose a sample of families of four vacationing at Niagara Falls resulted in a sample mean of per day and a sample standard deviation of . a. Develop a confidence interval estimate of the mean amount spent per day by a family of four visiting Niagara Falls (to decimals). $ to $ b. Based on the confidence interval from part (a), does it appear that the population mean amount spent per day by families visiting Niagara Falls differs from the mean reported by the American Automobile Association
Answer:
(233.8436 ; 271.0564)
Yes
Step-by-step explanation:
Given :
Sample mean, xbar = 252.45
Sample standard deviation, s = 74.50
Sample size, n = 64
α = 0.05
The confidence interval :
Mean ± margin of error
Margin of Error = tα/2 * s/√n
df = n - 1 = 64 - 1 = 63
t(α/2, df = 63) = 1.998
Margin of Error = 1.998 * 74.50/√64
Margin of Error = 18.6064
The confidence interval :
252.45 ± 18.6064
(233.8436 ; 271.0564)
Comparing the confidence interval value and the mean value reported by the American Automobile Association ;it can be concluded that the mean reported by the American Automobile Association differ from the mean spent at Niagara Fall as 215.60 falls below the confidence interval.
The confidence interval is (233.8436 ; 271.0564).
We have given that the,
Sample mean, x bar = 252.45
Sample standard deviation, s = 74.50
Sample size, n = 64
α = 0.05
What is the confidence interval ?The confidance interval is Mean ± margin of error.
[tex]Margin of Error = t\alpha /2 \times s/\sqrt{n}[/tex]
[tex]df = n - 1 \\df= 64 - 1 \\df= 63[/tex]
[tex]t(\alpha/2, df = 63) = 1.998[/tex]
[tex]Margin of Error = 1.998 \times 74.50/\sqrt64[/tex]
Margin of Error = 18.6064
The confidence interval is given by,
252.45 ± 18.6064
Therefore we get the confidence interval is (233.8436 ; 271.0564)
Comparing the confidence interval value and the mean value reported by the American Automobile Association ;it can be concluded that the mean reported by the American Automobile Association differ from the mean spent at Niagara Fall as 215.60 falls below the confidence interval.
