The measure of ∠5 is 62 degrees if the value of ∠2 is 48 degrees and ∠3 is 62 degrees. Option B is correct.

First, let us understand the types of angles formed by parallel and transversal lines:

Corresponding Angles — Corresponding angles are angles on the same side of a transversal that are either above or below the lines.

Alternate Interior Angles - Alternate interior angles are the pairs of interior angles on opposing sides of the transversal.

Alternate Exterior Angles - Alternate exterior angles are the pairs of exterior angles on opposing sides of the transversal.

Consecutive interior angles - Internal angles on the same side of a transversal are also known as consecutive interior angles, related angles, or co-interior angles.

We are given:

∠2 is 48 degrees and ∠3 is 62 degrees.

We need to find the ∠5.

From the given figure we can see that;

∠3 and ∠5 are alternate interior angles.

So, ∠3 = ∠5 = 62 degrees.

So, the measure of ∠5 is 62 degrees.

Thus, the measure of ∠5 is 62 degrees if the value of ∠2 is 48 degrees and ∠3 is 62 degrees. Option B is correct.

An equation of the line in point-slope form that contains the point (-2, 5) and has a slope of 1/3 is y - 5 = 1/3(x + 2).

In Mathematics, the point-slope form can be defined as a type of equation that is typically used when the slope of a straight line and one of the points on this line is given (known).

Mathematically, the point-slope form of a straight line is given by this equation:

y - y₁ = m(x - x₁)

Where:

Substituting the given parameters into the formula, we have;

y - y₁ = m(x - x₁)

y - 5 = 1/3(x - (-2))

Answer:

m∠D = 54°

Step-by-step explanation:

The sum of the measures of the interior angles of a triangle is 180°.

The sum of the measures of an interior angle and its corresponding exterior angle is 180°.

With this knowledge, we can construct the equation:

50° + (3x + 18)° + (180 - (8 + 8x))° = 180°

and solve for x.

50° + (3x + 18)° + (180 - 8 - 8x)° = 180°

(50 + 18 + 180 - 8)° + (3x - 8x)° = 180°

240° - 5x° = 180°

5x° = 240° - 180°

5x° = 60°

x° = 12°

Now, we can solve for m∠D by plugging in the x value that we solved for.

m∠D = (3x + 18)°

m∠D = 3(12)° + 18°

m∠D = 36° + 18°

m∠D = 54°

The percent of error concerning Alton's estimated attendance and actual attendance at the band concert is 30%.

The percent of error is a measure showing how big an error is between the estimate and actual results.

The smaller the percent of error the closer the estimate is to the actual observations, and vice versa.

Actual Observed Value = 200

Expected Value = 260

Percentage of error = (Expected Value - Observed Value) ÷ Actual Value

= (260 - 200)/200

= 60/200

= 0.3

= 30%

Thus, we can conclude that Alton made a 30% error in his estimate of attendance at the band concert.

The exponential model for the lily pad colony is L(t) = A[tex](1+r)^{kt}[/tex] and the values of A=5 and k=1.2.

Over time, anything grows in quantity through an exponential growth process. When a quantity's rate of change over time (or derivative) is proportional to the quantity itself, this phenomenon takes place. A number that is increasing exponentially is referred to as a function, and the exponent, which stands for time, is the variable that represents time (in contrast to other types of growth, such as quadratic growth).

When a quantity decrements with time, it is considered to be experiencing exponential decay rather than a positive constant of proportionality. It is also known as geometric growth or geometric decay when the definition's discrete domain has equal intervals since the values of the function form a geometric progression.

Given, there are 5 lily pads that are found in a pond

And after 30 days, there are 16 lily pads in that pond

Here, a=5

b) The p-value is: 0.1342.

c) The conclusion is that the null hypothesis is not rejected.

d) The final conclusion is that there is not sufficient evidence to conclude that the population mean is of 6.

The standard deviation for the population is unknown, only the sample standard deviation is known, hence the t-distribution is obtain the test statistic.

The test statistic is given by the equation presented as follows:

[tex]t = \frac{\overline{x} - \mu}{\frac{s}{\sqrt{n}}}[/tex]

In which the variables of the equation are given as follows:

For this problem, the values of these parameters are as follows:

[tex]\overline{x} = 5.83, \mu = 6, s = 2.11, n = 189[/tex]

Hence the test statistic is:

[tex]t = \frac{\overline{x} - \mu}{\frac{s}{\sqrt{n}}}[/tex]

[tex]t = \frac{5.83 - 6}{\frac{2.11}{\sqrt{189}}}[/tex]

t = -1.11.

The p-value is obtained using a t-distribution calculator, with a left-tailed test, as we are testing if the mean is less a value, with 189 - 1 = 188 df and t = -1.11, hence it is of 0.1342.

The probability that the sample proportion of the Republicans will differ from the population by more than 4% is 95.56%

The probability is calculated using z score, this is used to determine the amount of difference a sample, X is from the standard deviation

The z score is given by the formula

z = (X - μ) / σ

Definition of variables

population mean, μ  = p = 50% = 0.5

sample size, n = 629

standard deviation, σ

= √{(p(1 - p)) / n}

= √{(0.50(1 - 0.50)) / 629}

= √{(0.50 * 0.50) / 629}

= 0.0199

Differ by more than 4% is differ by 50% + 4%

X = 50% + 4% = 54% = 0.54

The probability of more than 54% P = P(p > 54%) = P(p > 0.54)

P(p > 0.54) = 1 - P(p < 0.54)

Z score for z < 0.54

z = (X - μ) / σ

= (0.54 - 0.50) / 0.0199

= 2.01

p value for z < 2.01 = 0.0444

P(p > 0.54) = 1 - P(p < 0.54)

The future value of the account in 3 years is $15,918.

What is a future value?

The worth of a current asset at some point in the future based on an estimated rate of growth is known as future value (FV). For investors and financial planners, the future value is crucial because they use it to predict how much an investment made now will be worth in the future.

Here, we have

FV  =C×[ ((1+i)ⁿ −1)/i]

where:

C = cash flow per period

i = interest rate

n = number of payments

By applying the future value formula, we get

= ​$5,000×[ ((1+0.06)³ −1)/0.06 ]

= $5,000×3.1836

An inequality in mathematics is a relation that compares two numbers or other mathematical expressions in an unequal way. The majority of the time, size comparisons between two numbers on the number line are made. Different types of inequalities are represented by a variety of notations.

The symbols we use in Inequality Expressions are

Not equal ' ≠ '  

Greater than  ' > '

Less than ' < '

Less than or equal  ' ≤ '

Greater than or equal ' ≥'

Here we have

William plans to buy the new Callaway Rogue for at least $ 550

The amount that William saved = $ 325

The amount he earns each time he details his parents = $ 20

Here we don't know how many times he detailed his parents,

So represent it with a variable x

After detailing x times the amount he earned will equal $ 20x

The total amount that William will have = $ 325 + $ 20x

William wants at least $550

Therefore,

The inequality that will represent the above situation is

=> 325 + 20x ≥ 550 ------(1)

Now solve the above inequality to get the value of x

=> 65 + 4x ≥ 110

=> 4x ≥ 45

Answer:   $11.50

==================================================

Explanation:

x = cost of one burger

y = cost of one hot dog

3 burgers = 3x dollars

2 hot dogs = 2y dollars

3 burgers + 2 hot dogs = 3x+2y = 8 dollars

The first equation to set up is 3x+2y = 8 which is based on the info of what Ricky purchased.

Through similar logic, the other equation is x+2y = 6 based on what Betty ordered.

This is the system of equations

[tex]\begin{cases}3x+2y = 8\\x+2y = 6\end{cases}[/tex]

There are a few approaches we could take. I'll use substitution.

Let's isolate x in the 2nd equation.

x+2y = 6

x = -2y+6

Then plug this into the 1st equation. Solve for x.

3x + 2y = 8

3(-2y+6) + 2y = 8

-6y+18+2y = 8

-4y+18 = 8

-4y = 8-18

-4y = -10

y = -10/(-4)

y = 2.50 dollars is the cost of one hot dog

Then,

x = -2y+6

x = -2*2.50+6

x = -5+6

x = 1 dollar is the cost of one burger

-----------------------

Check:

The x and y values are confirmed correct.

------------------------

The last thing to find out is how much is spent if Billy bought 4 burgers and 3 hot dogs

4x+3y = 4*1 + 3*2.50 = 4 + 7.50 = 11.50 dollars is the final answer

This assumes that Billy is paying for himself and the other people pay for themselves as well. If Billy is paying for everyone, then the total comes to 11.50+8+6 = 25.50 dollars.

let the number be n then double the number is 2n and

2n + 32 = [tex]\frac{2}{9}[/tex] n

multiply through by 9 to clear the fraction

18n + 288 = 2n ( subtract 2n from both sides )

16n + 288 = 0 ( subtract 188 from both sides )

16n = - 288 ( divide both sides by 16 )
