15028 is not a perfect square.

Smallest number by which 15028 can be divided to make it perfect square is 13.

If, we divide 15028 by 13, answer is 1156.

Therefore,

Answer:

Consider the line 6x-7y = 7.

What is the slope of a line parallel to this line?

What is the slope of a line perpendicular to this line?

Step-by-step explanation:

Using the binomial probability function formula, the probability that the sample contains exactly 2 graduate students is 0.215.

The probability that the sample of 5 students contains exactly 2 graduate students using the binomial probability function can be determined by using the formula below:

P(X = k) = (n choose k) * p^k * (1 - p)^(n - k)

where n is the sample size, k is the number of successes, p is the probability of success, and (n choose k) = n! / (k! * (n - k)!) denotes the number of ways to choose k items from a set of n items.

Using the formula above and the information given, the probability of the sample containing exactly 2 graduate students can be calculated as follows:

P(X = 2) = (5 choose 2) * (0.32)² * (1 - 0.32)^(5 - 2) = 0.215

Where (5 choose 2) = 5! / (2! * (5 - 2)!) = 10 is the number of ways to choose 2 graduate students from a sample of 5 students.

A cost that changes in total as output changes is indeed a variable cost. Variable costs are expenses that vary in direct proportion to the level of production or business activity. As output increases, variable costs increase, and as output decreases, variable costs decrease. Examples of variable costs include direct labor, raw materials, and sales commissions.

We can conclude that the marketing manager's claim is true.

To determine whether the marketing manager's claim is true, we need to conduct a hypothesis test.

Let p be the proportion of all children aged 8-12 who have cell phones. The marketing manager claims that p > 0.5, while the national consumers group survey found that 39/54 or p' = 0.722 have cell phones.

The null hypothesis is that the true proportion of children with cell phones is less than or equal to 0.5:

H0: p ≤ 0.5

The alternative hypothesis is that the true proportion of children with cell phones is greater than 0.5:

Ha: p > 0.5

We will conduct a one-tailed hypothesis test with a level of significance of 0.05.

Under the null hypothesis, the sample proportion follows a binomial distribution with parameters n = 54 and p = 0.5. The standard error of the sample proportion is given by:

SE = √[p(1-p)/n] = √[0.5(1-0.5)/54] = 0.070

The test statistic is calculated as:

z = (p' - p) / SE = (0.722 - 0.5) / 0.070 = 3.14

The critical value for a one-tailed test with a level of significance of 0.05 is 1.645, using the standard normal distribution table.

Since the test statistic (z = 3.14) is greater than the critical value (1.645), we reject the null hypothesis and conclude that there is sufficient evidence to support the claim that more than half of the children aged 8-12 have cell phones.

Therefore, we can conclude that the marketing manager's claim is supported by the data from the survey.

Step-by-step explanation:

Answer:

Therefore, The Boat is Approaching the Dock at a Rate of 2ft/sec When the point of attachment is:  14ft from the dock.

Make a plan:

Let  X be the Distance between the Boat and the Dock

Y  be the Length of the Rope

We will use the Pythagorean Theorem to relate X  and Y

Then Differentiate with respect to Time to find the Rate at which the Boat is Approaching the Dock.

1 - Write the Pythagorean Theorem equation:

X^2  + 1^2 = Y^2

2 - Differentiate Both Sides with respect to Time (t):

2x dx/dt  =  2y dy/dt

3 - Given dy/dt  =  -2ft/sec, and  y = 14ft

Solve for,  dx/dt, When  X = 14ft

2(14)dx/dt  =  2(14)( -2 )

4 - Solve For:

dx/dt

dx/dt  =  -2ft/sec

Draw the conclusion:

Therefore, The Boat is Approaching the Dock at a Rate of 2ft/sec When the point of attachment is:  14ft from the dock.

Percentage Change = (ΔV/IV₁I) × 100

Constant rate of Change = (y₂ - y₁)/ (x₂ - x₁)

Constant Percentage Change:

This means that after t period the something has grown to \(g^{t} = 1.10^{t}\) it original value .

percentage change formula equals the change in value divided by the absolute value of the original value multiplied by 100.

Constant rate of Change:

In which the rate does not change between different points in the function. in short, constant rate of change refers to the comparison of the way two quantities changes. in equation, the constant rate of change can be seen as a slope.

The vector AC can be expressed in terms of vector AB and vector BC as follows:

In Euclidean geometry, a parallelogram is described as a simple quadrilateral with two pairs of parallel sides.

We have that  ABCD is a parallelogram, vector AC is equivalent to vector BD, which can be expressed in terms of vector AB and vector BC as follows:

Vector BD = Vector AB + Vector BC

We can substitute BD for AC in the above equation because  vector AC is equivalent to vector BD, we obtain the following:

Vector AC = Vector AB + Vector BC

In conclusion, vector AC can be expressed in terms of vector AB and vector BC as the sum of vector AB and vector BC.

It means that there is a positive correlation between int

The vector t, which has a magnitude of 14, and a direction of 51 degrees, can be expressed in component form as t = 12.0, 9.0>. This is the case because t has a direction of 51 degrees.

It is necessary to separate the vector t into its horizontal and vertical components before we can use component form to express the vector t. It has been determined that the magnitude of the vector is 14, and that the direction is 51 degrees.

Utilising the cosine function will allow us to determine the horizontal component. The formula for calculating the horizontal component, denoted by t_x, is as follows: t_x = magnitude * cos(direction). When we plug in the variables that have been provided, we get the formula t_x = 14 * cos(51°) 12.0.

We can use the sine function to figure out the value of the vertical component. The vertical component, denoted by t_y, can be calculated using the following formula: t_y = magnitude * sin(direction). When we plug in the variables that have been provided, we get the formula t_y = 14 * sin(51°) 9.0.

Therefore, the vector t with a magnitude of 14 and a direction of 51° may be expressed in component form as t = 12.0, 9.0>. This is because t represents the direction of the vector and t represents the magnitude.
