Answer: 55.3 is the correct ans

area of parallelogram=b*h

=55.3

the measure of the angle between the vectors u and v is 45 degrees.

To find the measure of the angle between two vectors, u and v, we can use the dot product formula:

u · v = |u| * |v| * cos(θ)

where u · v is the dot product of u and v, |u| and |v| are the magnitudes of u and v respectively, and θ is the angle between u and v.

First, let's calculate the dot product of u and v:

u · v = (-7)(-4) + (0)(4) = 28

Next, let's calculate the magnitudes of u and v:

|u| = √((-7)² + 0²) = √49 = 7

|v| = √((-4)² + 4²) = √32 = 4√2

Substituting these values into the dot product formula:

28 = (7)(4√2) * cos(θ)

Now, solve for cos(θ):

cos(θ) = 28 / (7 * 4√2) = 2 / √2 = √2

To find the angle θ, we can take the inverse cosine (cos^(-1)) of √2:

θ = cos⁻¹(√2)

Using a calculator, the value of cos⁻¹(√2) is approximately 45 degrees.

Therefore, the measure of the angle between the vectors u and v is 45 degrees.

The given statement, "The sampling distribution of a single proportion is approximately normal if the number of successes or the number of failures is greater than or equal to 10" is True.

The sampling distribution of a single proportion is approximately normal if the sample size is large enough and the number of successes or the number of failures is greater than or equal to 10. This is known as the normal approximation of the binomial distribution.

The normal approximation to the binomial distribution is based on the central limit theorem, which states that as the sample size increases, the sampling distribution of the sample means approaches a normal distribution, regardless of the shape of the population distribution. In the case of the binomial distribution, the sample mean is the proportion of successes, and as the sample size increases, the sampling distribution of the sample proportion approaches a normal distribution.

When the number of successes or the number of failures is less than 10, the normal approximation to the binomial distribution may not be valid, and alternative methods, such as the exact binomial distribution or the Poisson approximation, may need to be used.

Answer:

6 titles and 16 acts were elaborated

Step-by-step explanation:

Let the number of titles be t and the number of acts be a

Since the total is 22 operations:

a + t = 22 •••••••(i)

Total amount from titles = 3500 * t = 3500t

Total amount from acts = 2000 * a = 2000a

2000a + 3500t = 53,000 ••••••(ii)

From i, a = 22-t

Insert this in ii

2000(22-t) + 3500t = 53,000

44,000 - 2000t + 3500t = 53,000

1,500t = 53000-44000

1500t = 9000

t = 9000/1500

t = 6

But a = 22 -

= 22-6 = 16

If Bob only fixes 50 computers, his total loss is $3,750.

The total loss results from the negative difference between the total revenue and the total costs.

The total costs consist of variable and fixed costs.

The result is a loss when the total costs exceed the total revenue.  This result becomes a profit or income when the total revenue exceeds the total costs.

Equipment = $5,000

Premises = $6,000

Advertising = $4,000

Total fixed costs = $15,000

Variable cost per unit = $25

Selling price per unit = $250

Total number of computers fixed = 50

The total variable cost for 50 units = $1,250 (50 x $25)

The total costs (fixed and variable) = $16,250

The sales revenue for 50 units = $12,500 (50 x $250)

Loss = $3,750 ($12,500 - $16,250)

Thus, Bob will incur a total loss of $3,750 if he fixes only 50 computers based on his fixed and variable costs.

The results from the Family Lifestyles Project suggest that children raised by counterculture parents differ from those raised by parents with more traditional values.

The Family Lifestyles Project conducted research to explore the differences between children raised by counterculture parents and those raised by parents with more traditional values. The findings indicate that these two groups of children exhibit distinct characteristics and behaviors.

Children raised by counterculture parents, who embrace non-conventional or alternative lifestyles, may experience different socialization processes and environments compared to children raised by parents with traditional values. These children may have been exposed to unique belief systems, values, and practices that deviate from societal norms.

As a result, the study suggests that children raised by counterculture parents may demonstrate variations in their attitudes, beliefs, behaviors, and lifestyle choices. This could manifest in different educational preferences, career aspirations, social interactions, and perspectives on various social issues.

Overall, the research highlights the influence of parental values and lifestyles on child development and emphasizes the potential impact of counterculture parenting on shaping children's identities and behaviors.

Step-by-step explanation:

Angle XBC = 55 degrees because it is a corresponding angle with Angle AXC

and corresponding angles are equal or congruent.

Ok so angle XBC = 55 degrees and since this an isosceles triangle

XBC = XCB which means XCB = 55 degrees

Now to find angle BXC we know that all angles of a triangle add up to 180 degrees.

Angle XBC + Angle XCB + Angle BXC = 180 degrees

Let x represent angle BXC

55 + 55 + x = 180

110 + x = 180

x = 180 - 110

x = 70

∴ Angle BXC = 70 degrees

What is a supplementary angle?

In Mathematics and Geometry, a supplementary angle simply refers to two (2) angles or arc whose sum is equal to 180 degrees.

Additionally, the sum of all of the angles on a straight line is always equal to 180 degrees. In this scenario, we can reasonably infer and logically deduce that the sum of the given angles are supplementary angles:

m∠1 + m∠2 = 180° (Linear pair theorem).

the third-degree polynomial function with real coefficients, having the zeros 6 + i, 6 - i, and 7, is:

f(x) = (x² - 12x + 37)(x - 7)

To form a third-degree polynomial function with real coefficients such that the complex number 6 + i and the real number 7 are zeros, we can use the fact that complex zeros come in conjugate pairs.

Given that 6 + i is a zero, its conjugate 6 - i will also be a zero. Thus, the zeros of the polynomial are 6 + i, 6 - i, and 7.

To find the polynomial function, we start by forming the factors corresponding to each zero:

(x - (6 + i))   --> This corresponds to the zero 6 + i

(x - (6 - i))   --> This corresponds to the zero 6 - i

(x - 7)        --> This corresponds to the zero 7

To simplify the factors, we multiply them out:

(x - (6 + i))(x - (6 - i))(x - 7)

= ((x - 6) - i)((x - 6) + i)(x - 7)

= ((x - 6)² - i²)(x - 7)

= ((x - 6)² + 1)(x - 7)

Expanding the squared term:

= (x² - 12x + 36 + 1)(x - 7)

= (x² - 12x + 37)(x - 7)

Therefore, the third-degree polynomial function with real coefficients, having the zeros 6 + i, 6 - i, and 7, is:

f(x) = (x² - 12x + 37)(x - 7)

Former atheist myself. That was an interesting phase.

The predicted values of A, B, C, and D are: A = 595B = -0.5C = 600D = $6350, therefore, the correct option is IC.

Given,

Mean of X = 600

Standard deviation of X = 10

Mean of Y = $5000

Standard deviation of Y = 1000

Correlation r= 0.9

Future value of X = 595

Z score of X = (X- Mean of X) / Standard deviation of X= (595-600) / 10 = -0.5

Using the formula, Predicted y = average of y+ r* (Z score of X)* standard deviation of y

Predicted y = $5000 + 0.9 * (-0.5) * 1000 = $4750

The predicted value of Y for X = 595 is $4750.

Now, to find the values of A, B, C, and D; we need to calculate the Z score of X = 615 and find the corresponding predicted value of Y.

Z score of X = (X- Mean of X) / Standard deviation of X= (615-600) / 10 = 1.5

Predicted y = average of y+ r* (Z score of X)* standard deviation of y

Predicted y = $5000 + 0.9 * (1.5) * 1000 = $6350

The predicted value of Y for X = 615 is $6350.

Hence, the values of A, B, C, and D are: A = 595B = -0.5C = 600D = $6350
