Question 1-

To determine which two points would a line of fit go through to best fit the data on the scatter plot, we need to visually analyze the pattern of the data points and choose two points that the line would pass through to represent the overall trend.

Without the actual scatter plot provided, I am unable to directly analyze it. However, based on the given answer choices:

A. (1,9) and (9,5)

B. (1,9) and (5,7)

C. (2,7) and (4,3)

D. (2,7) and (6,5)

Since I don't have the scatter plot, I cannot accurately determine which points would best fit the data. I would recommend carefully reviewing the scatter plot and selecting the two points that seem to represent the general trend or pattern of the data. The two points that form a line that closely follows the general direction of the data points would be the best choices.

Question 2-

To determine the slope of the relationship between the number of hours Laila danced, x, and the money she raised, y, we need to examine the graph and calculate the slope using the formula:

Slope = (change in y) / (change in x)

However, since the graph is not provided, it is not possible to directly calculate the slope. However, we can still evaluate the given answer choices based on their explanations:

A. The slope is 1/4, which means that the amount the student raised increases by $0.75 each hour.

B. The slope is 4, which means that the amount the student raised increases by $4 each hour.

C. The slope is 12, which means that the student will finish raising money after 12 hours.

D. The slope is 20, which means that the student started with $20.

From the explanations provided, it seems that option B would be the most reasonable choice. A slope of 4 would indicate that for each additional hour Laila danced, she raised $4. However, without the actual graph, it is challenging to confirm the accuracy of the answer choice or its real-world interpretation.

The overall probability that all three players score their penalty is 28/75, only one player succeeds is 1/6, all three players fail is 1/50, and two players hit is 11/25.

Correct option is D. two hit (11/25).

This probability can be determined by first converting the odds of each player into probabilities and then using the law of probability to calculate the odds of various combinations of successes and fails.

The law of probability states that the probability of an event is the probability of success multiplied by itself the number of times the event happens.

For example, if a player has a probability of success of 2/3 for their penalty, then the probability of them scoring the penalty twice in a row would be (2/3)*(2/3) which is equal to 4/9. To calculate the probability that all three players score their penalty, the law of probability must be used.

To do this, first, the probability of success for each penalty must be calculated. Using the odds given, this would be 2/3 for the first player, 4/5 for the second player, and 7/10 for the third player. The overall probability of the three succeeding is then (2/3)*(4/5)*(7/10) which is equal to 28/75.

Correct option is D. two hit (11/25).

The probability of the soft drink machine filling a cup between 2121 and 3030 ounces with a normal distribution of the mean of 2727 ounces and a standard deviation of 33 ounces is 0.

It is given that the soft drink machine's output is normally distributed.

We know that for any normal distribution with X~(μ,σ)

f(z)= 1/σ√2π . e^(-(x - μ)²/2σ²),for all z ∈ R.

where  μ = The mean of the distribution

σ = the standard deviation of the distribution

Here

μ = 2727

σ = 33

We need to find

P(2121< x < 3030)

We know that the relation between a normal distribution and its Z-score is

P(a < X < b) = Φ((b- μ)/ σ)  -  Φ(a - μ/ σ)

here a = 2121  and  b = 3030

Therefore we get

P(2121< x < 3030) = Φ((3030- 2727)/ 33)  -  Φ(2121 - 2727/ 33)

= Φ((303)/ 33)  -  Φ(-606/ 33)

= Φ((303)/ 33)  -  Φ(-606/ 33)

= Φ((9.181818)  -  Φ(-18.363636)

From the Z score table, we know that the p-value will be

We are 90% confident that the true difference in proportions between France and the United States falls between -0.1783 and 0.1383.

What is proportion?

The size, number, or amount of one thing or group as compared to the size, number, or amount of another. The proportion of boys to girls in our class is three to one.

The point estimate for the difference in proportions between France and the United States is:

p₁ - p₂ = (60/120) - (26/50) = 0.5 - 0.52 = -0.02

We can use the following formula to calculate the standard error of the difference in proportions:

SE = √(p₁ * (1 - p₁) / n₁ + p₂ * (1 - p₂) / n₂)

where n₁ and n₂ are the sample sizes.

SE = √((0.5 * 0.5 / 120) + (0.52 * 0.48 / 50))

SE = 0.0936

To construct a 90% confidence interval, we can use the formula:

(point estimate) ± (critical value) * (standard error)

The critical value for a two-sided 90% confidence interval with 169 degrees of freedom (calculated as df = (p₁ * n₁ + p₂ * n₂) / (p₁ + p₂)) can be found using a t-distribution table or calculator.

For a 90% confidence level, the critical value is approximately 1.656.

Using these values, the 90% confidence interval for the difference in proportions is:

-0.02 ± 1.656 * 0.0936

which simplifies to:

-0.1783 to 0.1383

Therefore, we are 90% confident that the true difference in proportions between France and the United States falls between -0.1783 and 0.1383.

B. 180 sq cm

Step-by-step explanation:

if the area of the scale drawing is 20 cm then the width must be 5cm and the length is 4cm.

Since the scale factor is 1:3 you multiply the side lenghts by 3. So the width of the real object is 15 cm and the length is 12 cm.

Multiply L x W to get area, 15 x 12 = 180

The exponential distribution may be used to predict the failure rate of certain items over time. An LED light bulb has an expected lifetime of 25000 hours. Assuming that the lifetime of the LED light bulb follows the exponential distribution, the probability that it will last more than 3 years is closest to (C) 53%. Correct answer is option C

This is because the lifetime of an LED light bulb can be estimated using the following equation : P(x > 3 years) = 1 - P(x ≤ 3 years)where x is the lifetime of the LED light bulb.If we convert 3 years to hours, we get 3 * 365 * 24 = 26280 hours. As a result, P(x ≤ 3 years) = P(x ≤ 26280 hours)

Using the formula for exponential distribution, the probability of the LED light bulb failing after 26280 hours is : Probability = 1 - e^{-λx} Where λ is the failure rate per hour and x is the length of time in hours.We can now calculate the value of λ by dividing the expected lifetime of the bulb by the total number of hours.

 λ = 1/25000 hours  This implies that the probability of the LED light bulb failing after 26280 hours is : P (x ≤ 26280 hours)

Therefore, the probability that the LED light bulb will last more than 3 years is approximately 53 percent. The Correct answer is option C

The equation of the given conic, horizontal ellipse is (x - 5)²/5² + (y - 1)²/4² = 1 or 16x² + 25y² - 160x - 50y + 325 = 0.

In mathematics, an ellipse is the location of points in a plane so that their separation from a fixed point has a set ratio of "e" to their separation from a fixed line (less than 1). The conic section, which is the intersection of a cone with a plane that does not intersect the base of the cone, includes the ellipse. The eccentricity of the ellipse is symbolized by the constant ratio "e," the fixed point is known as the focus, and the fixed line is known as the directrix (d).

The ellipse formula equation aids in the algebraic representation of an ellipse. You may use the following formula to determine an ellipse's equation:

The ellipse's equation with a center at (0, 0) is as follows: x²/a² + y²/b² = 1.

An ellipse with a center at (h,k) has the following equation: (x - h)²/a² + (y - k)²/(b²) = 1, where a and b are the semi-major and semi-minor diameters.

In the question, we are given that the center (h,k) = (5,1), the major diameter = 10, or, a = 10/2 = 5, and the minor diameter = 8, or, b = 8/2 = 4.

Substituting in the equation, we get:

(x - 5)²/5² + (y - 1)²/4² = 1, in the general form, and,

16(x² + 25 - 10x) + 25(y² + 1 - 2y) = 100,

or, 16x² + 400 - 160x + 25y² + 25 - 50y = 100,

or, 16x² + 25y² - 160x - 50y + 325 = 0.

Thus, the equation of the given conic, horizontal ellipse is (x - 5)²/5² + (y - 1)²/4² = 1 or 16x² + 25y² - 160x - 50y + 325 = 0.

Step-by-step explanation:

The mean absolute deviation for the group of household incomes is approximately 14.8 (rounded to the nearest tenth).

To calculate the mean absolute deviation (MAD) for a group of data, we follow these steps:

Find the mean (average) of the data set.

Subtract the mean from each data point, obtaining the deviations.

Take the absolute value of each deviation.

Find the mean of the absolute deviations.

Given the household incomes for 10 different households:

38, 45, 76, 93, 50, 54, 29, 44, 62, 31

Let's calculate the MAD step by step:

Find the mean (average):

Mean = (38 + 45 + 76 + 93 + 50 + 54 + 29 + 44 + 62 + 31) / 10

Mean = 482 / 10

Mean = 48.2

Calculate the deviations:

Deviation for each data point = Data point - Mean

Deviation for 38 = 38 - 48.2 = -10.2

Deviation for 45 = 45 - 48.2 = -3.2

Deviation for 76 = 76 - 48.2 = 27.8

Deviation for 93 = 93 - 48.2 = 44.8

Deviation for 50 = 50 - 48.2 = 1.8

Deviation for 54 = 54 - 48.2 = 5.8

Deviation for 29 = 29 - 48.2 = -19.2

Deviation for 44 = 44 - 48.2 = -4.2

Deviation for 62 = 62 - 48.2 = 13.8

Deviation for 31 = 31 - 48.2 = -17.2

Take the absolute value of each deviation:

Absolute deviation for each data point = |Deviation|

Absolute deviation for -10.2 = 10.2

Absolute deviation for -3.2 = 3.2

Absolute deviation for 27.8 = 27.8

Absolute deviation for 44.8 = 44.8

Absolute deviation for 1.8 = 1.8

Absolute deviation for 5.8 = 5.8

Absolute deviation for -19.2 = 19.2

Absolute deviation for -4.2 = 4.2

Absolute deviation for 13.8 = 13.8

Absolute deviation for -17.2 = 17.2

Find the mean of the absolute deviations:

Mean Absolute Deviation (MAD) = (10.2 + 3.2 + 27.8 + 44.8 + 1.8 + 5.8 + 19.2 + 4.2 + 13.8 + 17.2) / 10

MAD = 148 / 10

MAD = 14.8

To the nearest tenth, this means that the mean absolute deviation for the group of household incomes is around 14.8.
