After 9 hours, Snowman A is 9 inches tall, and Snowman B is 7 inches tall. Therefore, Snowman A is taller than Snowman B after 9 hours.

Snowman A has an initial height of 36 inches and melts at a rate of 3 inches per hour.

We can write its equation as:

A(t) = 36 - 3t, where A(t) represents the height of Snowman A at time t hours after sunrise.

Snowman B has an initial height of 52 inches and melts at a rate of 5 inches per hour.

Its equation can be written as:

B(t) = 52 - 5t, where B(t) represents the height of Snowman B at time t hours after sunrise.

Now, we need to determine which snowman is taller after 9 hours. We will do this by plugging t = 9 into both equations:

A(9) = 36 - 3(9) = 36 - 27 = 9 inches

B(9) = 52 - 5(9) = 52 - 45 = 7 inches

After 9 hours, Snowman A is 9 inches tall, and Snowman B is 7 inches tall. Therefore, Snowman A is taller than Snowman B after 9 hours.

An equation of the line that passes through the point (2, 4) and is perpendicular to the line 8x + 7y − 4 = 0 is y = -4x + 4.

To find the equation of a line that passes through a given point and is perpendicular to another line, you can use the slope-intercept form of a linear equation, which is given by y = mx + b, where m is the slope of the line and b is the y-intercept, which is the point where the line crosses the y-axis.

In this case, the line 8x + 7y − 4 = 0 has a slope of -7/8. To find the equation of a line that is perpendicular to this line and passes through the point (2, 4), we need to find the slope of the perpendicular line, which is -1/(-7/8) = 8/7. Then, we can use the point (2, 4) and the slope (8/7) to find the y-intercept of the line, which is the value of b in the equation y = mx + b.

Substituting the coordinates of the point (2, 4) and the value of the slope (8/7) into the equation, we get 4 = (8/7) * 2 + b, which can be simplified to 4 = 16/7 + b. Solving for b, we get b = 4 - 16/7 = 28/7 - 16/7 = 12/7.

The standard deviation of the given data is approximately 288.9

To find the standard deviation of the given data, we will use the following terms: x-values (77, 88, 99, 1010, 1111), and the corresponding probabilities P(X=x) (0.1, 0.1, 0.2, 0.2, 0.4).

First, we need to calculate the mean (µ) of the data using the formula: µ = Σ[x * P(X=x)]

µ = (77 * 0.1) + (88 * 0.1) + (99 * 0.2) + (1010 * 0.2) + (1111 * 0.4) = 975.8

Next, we'll find the variance (σ²) using the formula: σ² = Σ[(x - µ)² * P(X=x)]

σ² = ((77 - 975.8)² * 0.1) + ((88 - 975.8)² * 0.1) + ((99 - 975.8)² * 0.2) + ((1010 - 975.8)² * 0.2) + ((1111 - 975.8)² * 0.4) ≈ 83464.36

Now, to find the standard deviation (σ), take the square root of the variance:

σ = √83464.36 ≈ 288.9

So, the standard deviation of the given data is approximately 288.9 (rounded to one decimal place).

Consecutive integers are those numbers that follow each other. They follow in a sequence or in order. For example, a set of natural numbers are consecutive integers.

For example, 4,5,6,7 are consecutive integers. This means that the difference between two consecutive numbers is 1.

If the first number is x, then the second number is (x+1 ) and the third number is (x+3)

The sum of the three number is x +( x+1) + (x+2) = 42

if the second number is x, then the first number is (x-1) and the third number is x+1

Independent variables are the factors that are manipulated or controlled by the researcher in a study. In the context of investigating the impact of a school nutrition program on grade performance of high school students, the independent variable would be the school nutrition program itself.

The researcher would design and implement the program, and this variable would be under their control.

Dependent variables, on the other hand, are the outcomes or variables that are measured in a study and are expected to change as a result of the independent variable. In this case, the dependent variable would be the grade performance of the students. The researcher would collect data on the grades of the students before and after the implementation of the nutrition program, and this would be the variable that is expected to be influenced by the independent variable.

In summary, the independent variable in this research design is the school nutrition program, while the dependent variable is the grade performance of the students. The researcher would manipulate the independent variable (implement the nutrition program) and then measure the dependent variable (student grades) to determine if there is an impact of the program on grade performance.

In sharecropping contracts, the landlord receives a fixed share of the output, while in fixed rent contracts, the landlord receives a fixed amount. On the other hand, in sharecropping contracts, the tenant receives a fixed share of the output, whereas in fixed rent contracts, the tenant receives a fixed amount.

Sharecropping and fixed rent contracts are two different arrangements between landlords and tenants in agricultural settings. In a sharecropping contract, the landlord's compensation depends on the output of the land. Specifically, the landlord receives a fixed share or proportion of the output produced by the tenant. This means that if the tenant's effort leads to a high output, the landlord's share will be larger, and if the output is low or zero, the landlord's share will be correspondingly smaller. The tenant, in turn, receives a fixed share of the output as their compensation.

On the other hand, in a fixed rent contract, the landlord's compensation is predetermined and does not depend on the output. The landlord receives a fixed amount of rent regardless of the output produced by the tenant. This fixed amount ensures that the landlord's income remains stable and is not influenced by the variability of agricultural output. In this case, the tenant also receives a fixed amount as their compensation, which is unaffected by the output.

The probability that the restaurant will receive two or more complaints in the next week is approximately 0.907.

Given that a fast food restaurant keeps record of the number of customer complaints per week and it has had 4 complaints per week. Assume that the number of complaints follows a Poisson distribution. We need to find the probability that the restaurant will receive two or more complaints in the next week. To find the probability of two or more complaints in the next week, we need to subtract the probability of zero or one complaint from 1, since the sum of all probabilities is 1.

So ,P(X ≥ 2) = 1 - P(X < 2). Now, the probability of having no complaints P(X = 0) = (e^-λλ^x)/x!

Putting x = 0 and λ = 4,P(X = 0) = (e^-4 4^0)/0! = 0.0183Approximately P(X = 0) = 0.02

Now, the probability of having one complaint P(X = 1) = (e^-λλ^x)/x!

Putting x = 1 and λ = 4,P(X = 1) = (e^-4 4^1)/1! = 0.0733Approximately P(X = 1) = 0.073

So, P(X < 2) = P(X = 0) + P(X = 1)P(X < 2) = 0.02 + 0.073 = 0.093

Therefore, P(X ≥ 2) = 1 - P(X < 2)P(X ≥ 2) = 1 - 0.093P(X ≥ 2) = 0.907

The correct answer is (D) A and B. Both a run of six points or more and an astronomical point can be rules for determining non-random patterns.

A run of six points or more refers to a sequence of data points that share a common characteristic or exhibit a consistent trend.

In statistical analysis, a run is a consecutive sequence of data points above or below a certain threshold. If there is a run of six points or more in a dataset, it suggests a non-random pattern or trend.

An astronomical point refers to a data point that significantly deviates from the expected pattern or falls outside the normal range of values. This point stands out as an outlier and may indicate a non-random pattern in the data.

By combining these two rules, A and B, we can identify non-random patterns in a dataset. A run of six points or more indicates a sustained trend, while an astronomical point signifies a significant deviation from the expected pattern.

It's important to note that a trend of three points or fewer, as mentioned in option (C), does not provide enough evidence to determine a non-random pattern. A trend of three points or fewer may still be subject to randomness or noise in the data, and it is not considered statistically significant.

Therefore, the correct answer is option (D) A and B, as both a run of six points or more and an astronomical point can help identify non-random patterns in data.
