Answer:

6. 12cm

7. 11.2 cm

9. 53 degrees

10. 37.5 cm

11. $ 693.12

Step-by-step explanation:

For questions 6-9 the triangle is congurent which means both their angles will be equal.

For the sides you can see that the second triangle is 1.5 times smaller than the first one as taking one of the sides 21/14= 1.5

So for Q. 6 we can multiply side PQ by 1.5.

For Q.7 divide CA by 1.5.

For Q. 10 we can do cross multiplication:

5/4 = x/30

= 150= 4x

= 37.5=x

For Q 11 we can see the size of the paper is 1.9 times bigger than the original one (38/20)

So the shorter side is 30.4 cm.

Then we have to find the area of the paper to multiply the two dimensions and we get 1155.2 square inches.

Then to figure out the money we multiply again and we get $693.12.

a. MRS = √(W/B)
b. Optimal bundle and total utility.
c. Adjusted income for constant utility.

a. The marginal rate of substitution (MRS) of walnuts for bananas is the rate at which you are willing to give up walnuts in exchange for one additional pound of bananas while keeping the utility constant. In this case, the MRS is equal to the ratio of the marginal utility of walnuts to the marginal utility of bananas. Since the utility function is U = √(W * B), the MRS can be calculated as MRS = √(W/B).

b. Using the Lagrangian approach, we can set up the following optimization problem: maximize U = √(W * B) subject to the constraint 2W + B = I, where W represents the pounds of walnuts, B represents the pounds of bananas, and I represents income. By solving the Lagrangian equation and the constraint, we can find the optimal consumption bundle and income level.

c. If the price of bananas doubles to $2 per pound, we need to determine the income required to maintain the same level of utility. With the new price, the constraint becomes 2W + 2B = I. By solving the Lagrangian equation again and substituting the new constraint, we can find the income level required to maintain the same level of utility.

Hence, x in terms of y is x = log(y) / log(5) found using the  common logarithms.

To solve the given problem with common logarithms and find x in terms of y, let's start with the provided information that is to use common logarithms.

Let us begin with a common logarithm defined as a logarithm to the base 10.

Therefore, we use the common logarithmic function of both sides of the given equation,

y = 5^x.

As a result, we get:log(y) = log(5^x)

We know that the power property of logarithms states that logb (a^c) = c * logb (a), where b is the base, a is a positive number, and c is a real number.

Using this property, we can rewrite the right-hand side of the above equation as:x log(5)

Now, we have:log(y) = x log(5)

To get the value of x in terms of y, divide both sides of the above equation by log(5).

We obtain the following:log(y) / log(5) = x

Therefore, x = log(y) / log(5).

To find the moments of inertia ix, iy, and i0 for the lamina of exercise 5, we need to first determine the coordinates of its center of mass. Once we have the center of mass coordinates, we can use the parallel axis theorem and perpendicular axis theorem to calculate the moments of inertia.

Assuming we have the coordinates (x,y) of each point mass of the lamina and its corresponding mass m, we can use the following formulas to find the center of mass:

x_cm = (Σmx) / M
y_cm = (Σmy) / M

where M is the total mass of the lamina.

Once we have the center of mass coordinates, we can use the following formulas to find the moments of inertia:

ix = Σm(y-y_cm)^2
iy = Σm(x-x_cm)^2
i0 = ix + iy

where ix and iy are the moments of inertia about the x and y axes, respectively, and i0 is the moment of inertia about an axis passing through the center of mass perpendicular to the plane of the lamina.

Note that we can use the parallel axis theorem to find the moments of inertia about any axis parallel to the x or y axis, and we can use the perpendicular axis theorem to find the moment of inertia about any axis perpendicular to the plane of the lamina.

The null hypothesis is always a statement about the population parameter or the absence of a relationship or difference between variables in a statistical hypothesis test. It is typically denoted as "H0" and assumes no effect or no difference exists.

The null hypothesis can take different forms depending on the specific research question. For example, in a study comparing the mean scores of two groups, the null hypothesis might state that the means are equal. In a correlation study, the null hypothesis could assert that there is no correlation between variables.

The null hypothesis acts as a baseline for comparison in hypothesis testing. Researchers aim to gather evidence against the null hypothesis to support an alternative hypothesis. Statistical analysis helps determine the likelihood of observing the obtained data if the null hypothesis were true.

By specifying a null hypothesis, researchers can objectively evaluate the evidence and draw conclusions about the relationship or difference they are investigating.

In summary, the null hypothesis is a statement about the population parameter or lack of relationship/difference, which serves as a reference point for hypothesis testing. It helps researchers assess evidence and draw conclusions based on statistical analysis.

To compute the chi-square (χ2) statistic for a contingency table, the entries in the table should be non-negative whole numbers and should represent counts or frequencies.

The entries should indicate the number of observations falling into each category or combination of categories. It is important to note that the χ2 test is a statistical test used to analyze the association between categorical variables, and it requires the data to be in the form of a contingency table with appropriate counts or frequencies.

The χ2 test is commonly used to examine the relationship between two categorical variables. The contingency table is a table that summarizes the observed frequencies or counts for each combination of categories of the variables. The entries in the contingency table should fulfill certain requirements to ensure the validity of the χ2 test. Firstly, the entries in the table should be non-negative whole numbers, as they represent counts or frequencies of occurrences. Negative values or non-integer values are not meaningful in this context.

Secondly, the entries should reflect the number of observations falling into each category or combination of categories. Each cell in the table represents the count or frequency of observations falling into a specific combination of categories. By ensuring that the entries in the contingency table satisfy these criteria, we can accurately compute the χ2 statistic and perform the appropriate statistical analysis to assess the association between categorical variables.

In the equation y = $7.20x + $790, "y" represents the total cost. An equation is a mathematical statement that shows the relationship between two or more variables. In this equation, there are two variables - "x" and "y". The variable "x" represents the number of units produced or sold, while "y" represents the total cost.

The coefficient of "x" in the equation, which is 7.20, represents the variable cost per unit. This means that for each unit produced or sold, there is an additional cost of $7.20. The constant term, which is $790, represents the total fixed costs. Fixed costs are those costs that do not vary with the number of units produced or sold.To find the total cost of producing or selling a certain number of units, we can plug in the value of "x" into the equation and solve for "y". For example, if we want to find the total cost of producing 100 units, we can substitute x=100 into the equation:
y = $7.20(100) + $790
y = $720 + $790
y = $1510
Therefore, the total cost of producing 100 units is $1510. In summary, "y" represents the total cost in the given equation, which is determined by both fixed and variable costs.
In the equation y = $7.20x + $790, "y" represents option C: total costs. This equation has two components: "$7.20x" represents the variable costs per unit, where x is the number of units, and "$790" represents the total fixed costs. By adding these two components together, you get the total costs (y) for producing x units.

The probability of coming out ahead after 30 spins is about 0.0732

The probability of winning on a single spin by betting on red (or black) is 18/38, which is approximately 0.4737.

Assuming each spin is independent of the others, the probability of winning exactly 15 times out of 30 is given by the binomial distribution with n=30 and p=0.4737. This can be calculated using the formula

P(X = k) = (n choose k) × \(p^k\) × \((1-p)^{n-k}\)

where X is the random variable representing the number of times we win in 30 spins, k is the number of times we win, "choose" denotes the binomial coefficient, and ^ denotes exponentiation.

Using a calculator or software that can calculate binomial probabilities, we find that

P(X = 15) = (30 choose 15) × 0.4737¹⁵ × 0.5263¹⁵ ≈ 0.0971

This means that the probability of winning exactly 15 times out of 30 is about 0.0971, or approximately 9.71%.

To find the probability of coming out ahead (winning more than you bet) after 30 spins, we need to consider all the possible outcomes. If we win exactly 15 times, we break even (winning 15 dollars and losing 15 dollars). If we win more than 15 times, we come out ahead. If we win less than 15 times, we come out behind.

The probability of winning more than 15 times can be calculated by adding up the probabilities of winning 16 times, 17 times, and so on, up to 30 times. This can be expressed as

P(X > 15) = P(X = 16) + P(X = 17) + ... + P(X = 30)

Using the same binomial distribution formula as before, we can calculate each term in this sum and add them up:

P(X > 15) ≈ 0.0732

Answer:

1. Growth rate of tree 3 ft per year, 2. Beginning height of tree 5 feet, rise/run = 3/1 = 3

Step-by-step explanation:

The solution is

1) The slope of the graph m = 3 represents the growth of the tree per year

2) The y-intercept means the initial height of the tree , when x = 0

What is an Equation of a line?

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation of line be represented as A

Now , the value of A is

Let the first point be P = P ( 3 , 14 )

Let the second point be Q = Q ( 1 , 8 )

Now , the slope of the two points on the line is given by

Slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Substituting the values in the equation , we get

Slope m = ( 14 - 8 ) / ( 3 - 1 )

Slope m = 6/2

Slope m = 3

Therefore , the slope is 3 feet per year

b)

The y intercept is calculated from the equation of line , when x = 0

So , the equation of line is given as

y - y₁ = m ( x - x₁ )

Substituting the values in the equation , we get

y - 14 = 3 ( x - 3 )

On simplifying the equation , we get

y - 14 = 3x - 9

Adding 14 on both sides of the equation , we get

y = 3x + 5

Now , when x = 0

y = 3 ( 0 ) + 5

y = 5 feet

From the graph we can see that , at 0 years the initial height of the tree is also 5 feet

Therefore , the y intercept is 5 feet

Hence , The slope of the equation is 3 and y intercept is 5
