Find the z-scores for the two normally distributed random variables, measured using different units of length.

a) x = 22 in, where X comes from N (15, 2.5)
b) y = 55.88 cm, where Y comes from N (38.1, 6.35)

Using the normal distribution, the z-scores are given as follows:

a) Z = 2.8.

b) Z = 2.8.

Normal Probability Distribution

The z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.

Item a:

The parameters are:

[tex]\mu = 15, \sigma = 2.5[/tex]

Hence the z-score is:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{22 - 15}{2.5}[/tex]

Z = 2.8.

Item b:

The parameters are:

[tex]\mu = 38.1, \sigma = 6.35[/tex]

Hence the z-score is:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{55.88 - 38.1}{6.35}[/tex]

Z = 2.8.

¿Cómo resolver un sistema de ecuaciones linear por igualación?

Los sistemas de ecuaciones basadas en entidades algebraicas se resuelven mediante procedimientos algebraicos.

Answers

According to the data, the cost of this house would increase by 0.08 thousand dollars ($80) for each additional square foot of living space.

How to determine the cost for an additional square foot?

By critically observing the scatter plot, we can logically deduce that it shows a linear trend. Thus, the slope of the line of best fit is given by a ratio of change in cost to the change in living space.

Next, we would approximate two points on the line of best fit and then find the slope as follows:

Slope, m = ΔC/Δx

Slope, m = (C₂ - C₁)/(x₂ - x₁)

Slope, m = (400 - 200)/(4000 - 1500)

Slope, m = 0.08.

Therefore, the cost of this house would increase by approximately 0.08 thousand dollars ($80) for each additional square foot of living space.

At the alternative hypothesis, we test if they are different, hence:

Mean is the average of a set of numbers. It is determined by adding the numbers together and dividing it by the total number

Mean = sum of the numbers / total number

130 = (128 + 127 + 123 + 122 + x) / 5

Where x represents the fifth score

130 = (500 + x) / 5

How to find the possible equations for a quartic polynomial that passes through the x-axis at three points

Herein we must construct at least a polynomial that satisfies all conditions described in the statement. According to the fundamental theorem of algebra, quartic functions may have no real roots, two real roots or four real roots, which means that one of the roots must have a multiplicity of 2.

The root with a multiplicity of 2 is x = 3 and both x = - 4 and x = - 2 have only a multiplicity of 1, then we have the following expression by using the factor form of the definition of polynomials:

f(x) = (x - 3)² · (x + 4) · (x + 2)

Now we expand the expression to get the standard form:

f(x) = (x² - 6 · x + 9) · (x² + 6 · x + 8)

f(x) = x⁴ - 6 · x³ + 9 · x² + 6 · x³ - 36 · x² + 54 · x + 8 · x² - 48 · x + 72

Let S represent the total amount of money in the savings account (in dollars), and let W represent the number of weeks Christine has been adding money. Write an equation relating S to W. Then use this equation to find the total amount of money in the savings account after 11 weeks.

Answers

Total amount of money in the savings account after 11 weeks is $1310.

Total money in the account =

Initial Money + Money added per week x Number of weeks

Given:

Initial Money = $650

Money added per week = $60

Total money in the account = S

Number of weeks = W

Substituting it in the above equation we get,

S = $650 + $60xW (General Equation)

Total amount of money in the savings account after 11 weeks

S = $650 + $60x11

S = $650 + $660

S = $1310

Thus total amount of money in the savings account after 11 weeks is $1310.

If
C(x) = 12000 + 400x − 2.6x2 + 0.004x3
is the cost function and
p(x) = 1600 − 8x
is the demand function, find the production level that will maximize profit. (Hint: If the profit is maximized, then the marginal revenue equals the marginal cost.)

Answers

Since profit can't be negative, the production level that'll maximize profit is approximately equal to 220.

How to find the production level that'll maximize profit?

The cost function, C(x) is given by 12000 + 400x − 2.6x² + 0.004x³ while the demand function, P(x) is given by 1600 − 8x.

Next, we would differentiate the cost function, C(x) to derive the marginal cost:

C(x) = 12000 + 400x − 2.6x² + 0.004x³

C'(x) = 400 − 5.2x + 0.012x².

Also, revenue, R(x) = x × P(x)

Revenue, R(x) = x(1600 − 8x)

Revenue, R(x) = 1600x − 8x²

Next, we would differentiate the revenue function to derive the marginal revenue:

R'(x) = 1600 - 8x

At maximum profit, the marginal revenue is equal to the marginal cost:

1600 - 8x = 400 − 5.2x + 0.012x

1600 - 8x - 400 + 5.2x - 0.012x² = 0

1200 - 2.8x - 0.012x² = 0

0.012x² + 2.8x - 1200 = 0

Solving by using the quadratic equation, we have:

x = 220.40 or x = -453.73.

Draw the graph of changing length of shadow of a stick from 12pm to 5pm.

Answers

The graph of changing length of shadow of a stick from 12pm to 5pm shows that length of shadow increases.

When an object (like the stick in the cartoon) blocks some of the Sun's light, it casts a shadow. The shadow always points away from the Sun. How long the shadow is depends on how low or high the Sun is in the sky. If the Sun is low, we see a longer shadow. Is the Sun is high, we see a shorter shadow.

Length of shadow due to the Sun's light is smallest when the Sun is vertically above. This happens at 12 noon.

How do you solve for zeros in an equation? ›

As we learned, finding the zero of a function means to find the point (a, 0) where the graph of the function and the y-intercept intersect. To find the value of a from the point (a, 0), you need to set the function equal to zero and then solve for x.

What is the real solution of the equation x3 125? ›

x3=125 Three solutions were found : x =(-5-√-75)/2=(-5-5i√ 3 )/2= -2.5000-4.3301i x =(-5+√-75)/2=(-5+5i√ 3 )/2= -2.5000+4.3301i x = 5 Rearrange: Rearrange the equation by subtracting what is ...

How many zeros does 125 have? ›

power of a prime p in n! Hence no of zeros in 125! =25+5+1=31. Hence there are 31 zeros in 125! .

What are trailing zeros of 125? ›

Hence, the answer is 31. Zeroes at the end of 125!

How do you find the zeros of a function F? ›

To find the zeros of a function f(x), we solve the equation f(x) = 0 for x. To find the roots of a function, we can use different methods to factorize. We can factorize the function using various methods such as: Grouping.

How do you factor to find zeros? ›

Step 1: Set your first factor equal to zero and solve. Step 2: Continue to set your factors equal to zero and solving until you have done this to all of the factors in your factored form polynomial. This factor does not give any real solutions. Step 3: List all of the zeros of your polynomial.

How many complex zeros does a function have? ›

Every polynomial function of positive degree n has exactly n complex zeros (counting multiplicities). For example, P(x) = x [ 5 ] + x [ 3 ] - 1 is a 5 [ th ] degree polynomial function, so P(x) has exactly 5 complex zeros.

Is x3 equal to 125? ›

The value of the cube root of 125 is 5. It is the real solution of the equation x3 = 125.

What x 3 is 125? ›

In fact, 125 = 5^3. So the only two whole numbers (greater than one) that multiply to produce 125 are 5 and 5^2, i.e. 5 and 25.

How do you find the number of complex roots in an equation? ›

No of complex roots = No of total roots - No of real roots .

What is the formula for finding a complex number? ›

The complex number is basically the combination of a real number and an imaginary number. The complex number is in the form of a+ib, where a = real number and ib = imaginary number. Also, a,b belongs to real numbers and i = √-1.

How do you find the order of zeros in complex analysis? ›

A zero is of order n if 0 = f (z0) = f (z0) = ··· = f(n−1)(z0), but f(n)(z0) = 0. A zero of order one (i.e., one where f (z0) = 0) is called a simple zero. Examples: (i) f(z) = z has a simple zero at z = 0.

How do you solve complex numbers over equations? ›

To solve an equation that has a complex number as a solution: Work with the purely real valued terms until no further simplification can be done and all that remains is an answer involving a negative radicand. Rewrite the complex root as the square root of a real number times the square root of -1.
