Measures of center are statistical tools used to determine the central tendency of a dataset, including mean, median, and mode.

The difference between these tools is how they capture the central tendency.

Variability of grades refers to how much grades fluctuate from week to week, which can be measured using statistical tools such as range, variance, and standard deviation. Without specific information about the test, it is not possible to draw conclusions.

However, analyzing the measures of center and variability can provide insights into student performance and grading consistency.

Further analysis, such as comparing grades to class averages or identifying patterns over time, may reveal additional information.

Answer:

V = 189

Step-by-step explanation:

V = \(\frac{1}{3}\)Bh

9 x 9 = 81

81 x 7 = 567

567 ÷ 3 = 189

The given vectors are:
Vector A = (-11, b, 2)
Vector B = (b, b^2, b)

The values of b for which the given vectors are orthogonal are 0, -3, and 3.

To find the values of b for which the given vectors are orthogonal, we need to use the dot product of the vectors.

To determine if two vectors are orthogonal, their dot product should be equal to zero.

The dot product is calculated as follows:

Dot Product (A, B) = A1 * B1 + A2 * B2 + A3 * B3

Substituting the components of Vector A and Vector B:

(-11 * b) + (b * b^2) + (2 * b) = 0

Now, simplify the equation:

-11b + b^3 + 2b = 0
b^3 - 9b = 0

Factor the equation:

b(b^2 - 9) = 0

Now, we can find the values of b:

b = 0
b^2 - 9 = 0
b^2 = 9
b = ±3

So, the values of b for which the given vectors are orthogonal are 0, -3, and 3.

(a) The mean of X, the number of adults who believe that the overall state of moral values is poor, can be calculated using the formula for the mean of a binomial distribution. In this case, the probability of an adult believing that the overall state of moral values is poor is given as 0.62. So, the mean is calculated as follows:

Mean (μ) = n * p

where n is the number of trials (100 adults) and p is the probability of success (0.62).

μ = 100 * 0.62 = 62

The mean of X is 62.

The standard deviation of X can be calculated using the formula for the standard deviation of a binomial distribution:

Standard deviation (σ) = √(n * p * (1 - p))

σ = √(100 * 0.62 * (1 - 0.62)) ≈ 4.15

The standard deviation of X is approximately 4.15.

(b) The correct interpretation of the mean is C.

For every 100 adults, the mean is the number of them that would be expected to believe that the overall state of moral values is poor. In this case, the mean of 62 indicates that, on average, out of every 100 adults surveyed, approximately 62 of them would be expected to believe that the overall state of moral values is poor.

(c) To determine whether it would be unusual for 66 of the 100 adults surveyed to believe that the overall state of moral values is poor, we need to consider the concept of unusual or statistically significant values.

Since we know the mean (62) and standard deviation (approximately 4.15) of the distribution, we can calculate the z-score for 66 using the formula:

z = (x - μ) / σ

where x is the observed value (66), μ is the mean (62), and σ is the standard deviation (approximately 4.15).

z = (66 - 62) / 4.15 ≈ 0.964

Next, we can compare the calculated z-score to the standard normal distribution to determine if it is considered unusual. Assuming a significance level of 0.05 (commonly used), we look up the z-score in the standard normal distribution table or use a statistical calculator.

The z-score of 0.964 corresponds to a p-value of approximately 0.166, which is greater than 0.05. Therefore, it would not be considered unusual if 66 of the 100 adults surveyed believed that the overall state of moral values is poor.

In summary:

The mean of X, the number of adults who believe that the overall state of moral values is poor, is 62. The standard deviation is approximately 4.15.

For every 100 adults, the mean is the number of them that would be expected to believe that the overall state of moral values is poor. In this case, 62 adults, on average, would be expected to believe so.

C. It would not be considered unusual if 66 of the 100 adults surveyed believed that the overall state of moral values is poor, as the calculated z-score of 0.964 corresponds to a p-value greater than 0.05.

Answer:

x = 53°, y = 42°

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Subtract the sum of the 2 given angles from 180° for x

x = 180° - (37 + 90)° = 180° - 127° = 53°

48° + y = 90° ( subtract 48° from both sides )

y = 42°

The cost to move in for Victoria and Michael is $7,645.

The cost to move into the apartment for Victoria and Michael can be found by calculating the sum of the application deposit, credit report cost, security deposit, first and last month's rent, and the broker fee.

Using the given information:

$150 is the application deposit

$35 is the cost of the credit report

Security deposit is 1 month's rent which is $2,200

First and last month's rent are also $2,200 each.

Thus, the total amount for these two months will be $4,400

The broker charged 2.5% of the yearly rent.

The yearly rent is $2,200 × 12 months = $26,400.

Therefore, the broker fee will be 2.5% of $26,400 which is $660.

Total cost to move in = $150 + $35 + $2,200 + $2,200 + $660 + $2,200 = $7,645

Therefore, the cost to move in for Victoria and Michael is $7,645.

Divide both sides by 3

20= 1/4

Multiply by 4

80= 4/4

80= 1 allowance

Answer: $80

Solving for the growth rate, we get:
Growth rate = 0.025 or 2.5%

Therefore, the growth rate of the stock is 2.5%.

The given double integral is ∫ ∫ (x² + y²)dx dy, and we need to evaluate it over the region in the positive quadrant where x+y≤1.

To evaluate this double integral, we can first determine the limits of integration for both x and y based on the given region. In the positive quadrant, x and y both range from 0 to 1.

Now, integrating the inner integral with respect to x, we get:

∫ (x² + y²)dx = (1/3)x³ + y²x + C1,

where C1 is the constant of integration.

Next, we integrate the resulting expression with respect to y:

∫ [(1/3)x³ + y²x + C1] dy = (1/3)x³y + (1/3)y³x + C1y + C2,

where C2 is another constant of integration.

Finally, we evaluate this double integral over the given region by substituting the limits of integration:

∫∫ (x² + y²)dx dy = ∫[0 to 1] ∫[0 to 1-x] (x² + y²)dy dx.

Performing the integration, we can find the numerical value of the double integral within the given region.
