Tutor O-Rama claims that their services will raise student SAT math scores at least 50 points. The average score on the math portion of the SAT is μ=350 and σ=35. The 100 students who completed the tutoring program had an average score of 385 points. Is the students’ average score of 385 points significant at the 5% and 1% levels to support Tutor O-Rama’s claim of at least a 50-point increase in the SAT score? (2 pts) Is the Tutor O-Rama students’ average score of 385 points significantly different at the 5% and 1% levels from the average score of 350 points on the math portion of the SAT? What conclusion can you make, based on your results, about the effectiveness of Tutor O-Rama’s tutoring? (2 pts)
Answer:
See below
Step-by-step explanation:
The score increase was 35 points. They claimed an increase of at least 50 points. For a significance level of 5%, the z-score for the situation needs to be at smaller than -1.645. For a significance level of 1%, the z-score needs to be smaller than -2.325
The z score for our situation: z = (385 - 350)/50 = 0.7
The average score of 385 of Tutor O-Rama scores is not significantly different from the average of the other students SAT scores. The evidence doesn't support their claim of being effective tutoring.
In quadrilateral ABCD the measures of, A , B , C, and D are the ratio of 1 :2:3:4, respectively. Find the measures of the four angles
So the ratio are 1:2:3:4 and all these add up to 10
Now we divide 360 by 10 resulting to 36
A=(36)
B=(72)
C=(108)
D=(144)
All these add up to 360 and has been divided equally according to the ration provided
Final answer:
To find the measures of the angles in quadrilateral ABCD with ratios 1:2:3:4, we set the angles as x, 2x, 3x, and 4x, and use the fact that their sum equals 360 degrees. Solving for x, we find x to be 36 degrees, which gives us the individual angles as 36 degrees, 72 degrees, 108 degrees, and 144 degrees respectively.
Explanation:
Calculating the Measures of the Angles in a Quadrilateral
Given that the measures of the angles A, B, C, and D in quadrilateral ABCD are in the ratio of 1:2:3:4 respectively, we first need to understand that the sum of the interior angles in a quadrilateral is always 360 degrees. To find the measure of each angle, we should express the ratio in terms of x, which would give us the angles as x, 2x, 3x, and 4x. Summing these and setting them equal to 360 degrees, we get the equation x + 2x + 3x + 4x = 360. Simplifying, we have 10x = 360, which when solved for x yields x = 36 degrees. Therefore, the measures of the angles are:
Angle A = 1x = 36 degrees
Angle B = 2x = 72 degrees
Angle C = 3x = 108 degrees
Angle D = 4x = 144 degrees
Hence, each angle's measure has been found using the given ratio and the property of the sum of interior angles in a quadrilateral.

notice, we use the 30-60-90 rule to get the length of RT, and then the 45-45-90 rule to get "x".
Answer:
Step-by-step explanation:
Remark
x is going to be the same thing as the hypotenuse of ΔRST. Find that and you have x.
Givens
<STR = 60°
RT = 2√3
Solution
Sin(60°) = opposite / hypotenuse
Sin(60°) = √3 / 2
Sin (60°)= 2 √3 / hypotenuse
hypotenuse = 2√3 // sin(60°)
hypoteneuse = 2√3 /√3/2
[tex]\text{hypotenuse = }\dfrac{2\sqrt{3}}{\dfrac{\sqrt{3} }{2}} = 2*2[/tex]
The √3's cancel. The answer is 4

Charles and his friends started a community group in 2008 to address problems in their neighborhood and to host civic events. The group began with 40 members, and the number of members changed over time as shown in the graph, where the y-axis represents the number of members and the x-axis represents the number of years since 2008.
Which statement is true?
A.
The function indicates that the number of members is increasing at a rate that is constant.
B.
The function indicates that the number of members is increasing at a rate that is not constant.
C.
The function indicates that the number of members is decreasing at a rate that is constant.
D.
The function indicates that the number of members is decreasing at a rate that is not constant.
Answer:
B.
Step-by-step explanation:
Because the graph shown is not constant, if you look at when it hits a whole unit. It is increasing because it is moving right.
The true statement is:
B.
The function indicates that the number of members is increasing at a rate that is not constant.
Step-by-step explanation:We could write the data points as is given on the graph as follows:
x y
0 40
1 50
2 60
3 80
4 100
5 120
6 150
7 190
8 240
9 300
10 370
Hence, the rate of change from x=0 to x=1 is:
[tex]Rate=\dfrac{50-40}{1-0}\\\\\\Rate=\dfrac{10}{1}\\\\\\Rate=10[/tex]
Rate of change from x=3 to x=5 is:
[tex]Rate=\dfrac{120-80}{5-3}\\\\\\Rate=\dfrac{40}{2}\\\\\\Rate=20[/tex]
Hence, the rate is not constant.
Also we could see that with the increasing value of x the y-value also increases.
Hence, option: B is the correct answer.

The lengths of plate glass parts are measured to the nearest tenth of a millimeter. The lengths are uniformly distributed with values at every tenth of a millimeter starting at 590.1, and continuing through 590.8. Determine the mean and variance of the lengths. (a) mean (in tenths of millimeters) Round your answer to two decimal places (e.g. 98.76). (b) variance (in tenths of millimeters2) Round your answer to three decimal places (e.g. 98.765). (a)
Answer:
A) μ = 590.45 mm; B) σ² = 0.053 mm
Step-by-step explanation:
To find the mean, we add together all of the values and divide by the number of data values:
590.1+590.2+590.3+590.4+590.5+590.6+590.7+590.8 = 4723.6
There are 8 data values; this gives us
4723.6/8 = 590.45
To find the variance, we subtract each of the data values from the mean. We then square this difference, and find the mean of the squares:
590.1-590.45 = -0.35; (-0.35)² = 0.1225
590.2-590.45 = -0.25; (-0.25)² = 0.0625
590.3-590.45 = -0.15; (-0.15)² = 0.0225
590.4-590.45 = -0.05; (-0.05)² = 0.0025
590.5-590.45 = 0.05; (0.05)² = 0.0025
590.6-590.45 = 0.15; (0.15)² = 0.0225
590.7-590.45 = 0.25; (0.25)² = 0.0625
590.8-590.45 = 0.35; (0.35)² = 0.1225
(0.1225+0.0625+0.0225+0.0025+0.0025+0.0225+0.0625+0.1225)/8
= 0.42/8 = 0.0525 ≈ 0.053
(a) The mean of the glass parts rounded to nearest tenths of millimeters
= 590.45 and (b) Variance in tenths of millimeters is = 0.053 mm.
What is mode ?In a given set of data one which repeats most frequently is called the mode of the given data set.
To obtain the mean we add together all of the values and divide by the number of data values.
590.1+590.2+590.3+590.4+590.5+590.6+590.7+590.8 = 4723.6
There are 8 data values; this gives us
4723.6/8 = 590.45
To find the variance, we subtract each of the data values from the mean and we square this difference to find the mean of the squares.
590.1-590.45 = -0.35; (-0.35)² = 0.1225
590.2-590.45 = -0.25; (-0.25)² = 0.0625
590.3-590.45 = -0.15; (-0.15)² = 0.0225
590.4-590.45 = -0.05; (-0.05)² = 0.0025
590.5-590.45 = 0.05; (0.05)² = 0.0025
590.6-590.45 = 0.15; (0.15)² = 0.0225
590.7-590.45 = 0.25; (0.25)² = 0.0625
590.8-590.45 = 0.35; (0.35)² = 0.1225
(0.1225+0.0625+0.0225+0.0025+0.0025+0.0225+0.0625+0.1225)/8

The height, f(x), of a bouncing ball after x bounces is represented by f(x) = 80(0.5)^x. How many times higher is the first bounce than the fourth bounce?
A.
2
B.
4
C.
6
D.
8
Answer:
D) 8
Step-by-step explanation:
Given function for height = f(x) = 80(0.5)^x
It shows that the height of ball after any bounce can be calculated by putting bounce number in place of x in this equation.
so, height after first bounce f(1) is calculated by placing 1 in place of x
f(1) = 80(0.5)^1
f(1) = 80(0.5)
f(1) = 40
Similarly, the height after 4th bounce f(4)
f(4) = 80(0.5)^4
f(4) = 80(0.0625)
f(4) = 5
Therefore, the height of 1st bounce is 40/5 = 8 times higher than the fourth bounce. So, option D is correct.
The first bounce is 8 times higher than the fourth bounce. Option D (8) is correct.
The height of the bouncing ball is given by the function f(x) = 80(0.5)^x, where x represents the number of bounces. To find how many times higher the first bounce is than the fourth bounce, we'll calculate the heights for f(1) and f(4) and then compare them.
Calculate the height after the first bounce (x = 1):Therefore, the first bounce is 8 times higher than the fourth bounce, corresponding to option D (8).

x= 1, 7.
Answer:
x = 1
Step-by-step explanation:
Please express exponentiation using the symbol " ^ " : x^2 - 8x + 7 = 0
Let's solve this equations using "completing the square:"
x^2 - 8x + 7 = 0
1) Identify the coefficient of the x term. Here it's -8.
2) take half of that and square it: we get (-4)² = 16
3) insert " +16 - 16 " between the 8x and the 7:
x^2 - 8x + 16 - 16 +7 = 0
4) Rewrite this perfect square:
(x - 4)² - 16 + 7 = 0 -> (x - 4)^2 = 9
5) Solve for (x -4) by taking the square root of both sides:
x - 4 ± sqrt(9) -> x - 4 ± 3
6) Solve for x: x = 4 ± 3, or x = 7 and x = 1.
7) Take the lesser root of 7 and 1. That would be x = 1. Answer B is correct.
Solve for x. -7/8x = -5

Santos walks 2 kilometers south and then a certain number of kilometers east. He ends 5 kilometers away from his starting position.How many kilometers east did Santos walk?
Answer:
4.6 Or 4.60
Step-by-step explanation:
Like the other person said, 4.56. The question says "round to the nearest tenth" so 4.56 rounds to 4.60
Hope it helps~
To determine how many kilometers east Santos walked, we can use the Pythagorean theorem to find the distance traveled for each leg of the journey.
Explanation:To determine how many kilometers east Santos walked, we need to use the Pythagorean theorem to find the distance traveled for each leg of the journey. Since he ends up 5 kilometers away from his starting position, we can form a right triangle with the hypotenuse representing the total distance walked.
Let's assume Santos walked x kilometers east. The other leg of the triangle represents the 2 kilometers south he walked. Using the Pythagorean theorem, we have x2 + 22 = 52.
This simplifies to x2 + 4 = 25. Subtracting 4 from both sides gives us x2 = 21. Taking the square root of both sides, we find that x ≈ 4.58. Therefore, Santos walked approximately 4.58 kilometers east.

A rectangular price tag has an area of 36 square centimeters. Its perimeter is 26 centimeters. What are the dimensions of the price tag?
Final answer:
The dimensions of the price tag are 9 cm by 4 cm, which are found by solving two equations derived from the given area and perimeter.
Explanation:
The student is asking for the dimensions of a rectangular price tag that has an area of 36 square centimeters and a perimeter of 26 centimeters. To solve this, we need to use two formulas: one for area (A = length × width) and one for perimeter (P = 2 × (length + width)).
First, let's denote the length of the rectangle by l and the width by w. The given area, 36 cm2, implies that l × w = 36.
Second, we know the perimeter is 26 cm, which gives us the equation 2 × (l + w) = 26. Dividing both sides by 2, we get l + w = 13.
This system of equations can be solved using substitution or elimination. If we rearrange the perimeter equation to express one variable in terms of the other (for instance, w = 13 - l), we can then substitute this expression into the area equation. Solving for l and w afterwards will give us the required dimensions.
Through solving, we find that the dimensions of the rectangle are 9 cm by 4 cm, since 9 × 4 = 36 and 2(9 + 4) = 26.

The triangle solver app on your calculator, phone, or tablet can solve this for you readily. There are on-line triangle solvers, too.
___
For solution "by hand", the Law of Cosines is useful. It tells you ...
a^2 = b^2 + c^2 -2ab·cos(A)
Then the angle A can be found as ...
cos(A) = (b^2 +c^2 -a^2)/(2ab) = (3^2 +7^2 -5^2)/(2·3·7) = 33/42 = 11/14
A = arccos(11/14) ≈ 38°

In formulas like the Law of Cosines or the Law of Sines, the uppercase letters stand for the measures of angles, and the lowercase letters stand for their opposite side lengths.

Answer:
0.731 < p < 0.775
Step-by-step explanation:
We have a sample proportion of 753/1000 = 0.753
We need to construct a 90% confidence interval for the population proportion. Since n > 30, we use the corresponding z-value of 1.645.
See attached photo for the formulas and construction of the confidence interval.
The 90% confidence interval for the proportion of American adults who think exercise is an important part of daily life is 0.749 to 0.757.
Explanation:To find the 90% confidence interval for the proportion of American adults who think exercise is an important part of daily life, we can use the formula for the confidence interval of a proportion. The formula is: CI = p ± Z * sqrt((p * (1-p))/n), where p is the sample proportion, Z is the z-score corresponding to the desired confidence level, and n is the sample size.
First, we need to calculate the sample proportion: p = 753/1000 = 0.753.
Next, we need to find the z-score for a 90% confidence level. Looking up the z-score in the standard normal distribution table, we find that the z-score for a 90% confidence level is approximately 1.645.
Now we can plug in the values into the formula: CI = 0.753 ± 1.645 * sqrt((0.753 * (1-0.753))/1000).
Calculating the expression inside the square root gives us approximately 0.0027. Plugging this value into the formula gives us the 90% confidence interval for the proportion: CI = 0.753 ± 1.645 * 0.0027.
Calculating this expression gives us the lower and upper bounds of the confidence interval: CI = 0.753 ± 0.0044.
