Answer:

x = 15

Step-by-step explanation:

That diagram leaves a whole lot to be desired. It took a bit to figure out what was going on.

The entire angle is 89 degrees.

It is made up of three angles:

<1 = 30

<2 = x

<3 = 44

<1 + <2 + <3 = 89

30 + x + 44 = 89

74 + x = 89

x = 89 - 74

x = 15

The dollar interval would be ± 6.70 to present in order to obtain a probability of 0.500.

What is probability?

Probability is a branch of mathematics that calculates the likelihood of an experiment occurring. We can know everything from the chance of getting heads or tails in a coin to the possibility of error in research by using probability.

z value for the probability of 0.5  is 0.67

standard error = sd/√n = 80/√64 =10

dollar interval = z*se

                      = 0.67*10

                       =6.70

Hence, the dollar interval would be ±6.70.

1945 men and 2849 women register to audition for a singing competition. The number of participants who are not successful in their auditions what’s five times the number of those who are successful. There are 799  participants were successful.

The successful  participants  can be calculate by solving a linear equation as follows

First, it's crucial to understand linear equations.

Equation connects the two algebraic expressions with an equal to sign to demonstrate the equality between the two algebraic expressions.

Linear equations are those with one degree.

In this case, a linear equation must be resolved.

1945 for the men's total

Women are present in 2849.

Participants in total: 1945 + 2849 = 4794

Let x be the proportion of participants that were successful.

Men who failed were 5 times as numerous.

Participants in total: 5x + x = 6x

Due to the issue,

The linear formula is

6x = 4794

x = 4794/6

x = 799

799 of the participants had success.

Answer:

5

Step-by-step explanation:

Solve the equation: 9.99+0.35_< 12

solving it would give you 5.7428571. You can just take the five.

The inequality is 12 ≥ 9.99 + n(0.35) and the most number of toppings are 6.

In mathematics, "inequality" refers to a relationship between two expressions or values that are not equal to each other. To solve the inequality, you may multiply or divide each side by the same positive number, add the same amount to each side, take the same amount away from each side, and more. You must flip the inequality sign if you multiply or divide either side by a negative number.

Given:

The cost of a cheese pizza is $9.99 plus $0.35 for each additional topping, t.

To write an inequality that can be used to represent the cost of a pizza that is at most $12:

Let n be the extra toppings.

12 ≥ 9.99 + n(0.35)

To find the number of toppings that a pizza can have and still be at most $12:

12 ≥ 9.99 + n(0.35)

n(0.35) ≤ 2.01

n ≤ (2.01) / (0.35)

n ≤ 5.74

n ≤ 6

Therefore, the most number of toppings are 6.

Answer:

Average consumption ( mean )  =  9

MOE = 4

Step-by-step explanation:

We know that

CI   ( 5  ;  13 )

and   CI [ μ - MOE  ;  μ + MOE ]

From the above relations we get

μ - MOE = 5

μ + MOE = 13

Adding member to member these two equations we get

2*μ  =  18

μ = 9    and MOE = 13 - 9

MOE = 4

The probability of making it home for the holidays is 0.9582. The result is obtained by summing up probabilities of the two cases.

The condition shows that the probability of the flight cancelled is 22 percent. When it happens, there is a second option, a car seat with 81 percent probability.

Case 1: Making home by plane, the flight should not be cancelled.

P(flight not cancelled) = 1 - P(flight cancelled)

P(flight not cancelled) = 1 - 0.22

P(making home by plane) = 0.78

Case 2: Making home by car when the flight is cancelled.

P(making home by car) = P(flight cancelled) × P(car seat available)

P(making home by car) = 0.22 × 0.81

P(making home by car) = 0.1782

The probability of making home by either of the options is

= P(making home by plane) + P(making home by car)

= 0.78 + 0.1782

= 0.9582

Hence, the probability of making it home through the flight or by car is 0.9582.

Answer:

D. 3

Step-by-step explanation:

Answer:

The slope of a linear model can be calculated using the formula:

m = Δy / Δx

where:

Δy = change in y (the dependent variable, in this case, total cost)

Δx = change in x (the independent variable, in this case, number of candy bars)

This is essentially the "rise over run" concept from geometry, applied to data points on a graph.

In this case, we can take two points from the table (for instance, the first and last) and calculate the slope.

Let's take the first point (3 candy bars, $6.65) and the last point (25 candy bars, $48.45).

Δy = $48.45 - $6.65 = $41.8

Δx = 25 - 3 = 22

So the slope m would be:

m = Δy / Δx = $41.8 / 22 = $1.9 per candy bar

This suggests that the cost of each candy bar is $1.9 according to this linear model.

Please note that this assumes the relationship between the number of candy bars and the total cost is perfectly linear, which might not be the case in reality.

The convolution integral y(t) = x(t) * h(t) for the given pair of signals x(t) and h(t) can be computed as follows:

y(t) = ∫[x(τ) * h(t - τ)] dτ

1) x(t) = δ(t) and h(t) = δ(t - 2) * (t - 1)

The convolution integral becomes:

y(t) = ∫[δ(τ) * δ(t - τ - 2) * (τ - 1)] dτ

To evaluate this integral, we consider the properties of the Dirac delta function. When the argument of the Dirac delta function is not zero, the integral evaluates to zero. Therefore, the integral simplifies to:

y(t) = δ(t - 2) * (t - 1)

The convolution result y(t) is equal to the shifted impulse response h(t - 2) scaled by the factor of (t - 1). This means that the output y(t) will be a shifted and scaled version of the impulse response h(t) at t = 2, delayed by 1 unit.

In summary, for x(t) = δ(t) and h(t) = δ(t - 2) * (t - 1), the convolution integral y(t) = x(t) * h(t) simplifies to y(t) = δ(t - 2) * (t - 1).

In the give question, we have to calculate the deferred tax liability given the following items incurred in 2020 by company b.

Bonuses are tax deductible only in the year in which they are paid.

From the given question;

Accounting Income                   = 86000

Add Depreciation expence       = 6500

Less Tax Depreciation              = 4000

Less 2019 Bonus Paid in 2020 = 2630

Add 2020 accured Bonus         = 3500

Total Taxable Income                = 84670

Accounting income is more that the taxable income. Hence defffered tax liability will arise on the temporary taxable difference.

Temporary Taxable Difference = 86000-84670 = 1330

Concept

Circumference - The circumference of a circle is the length of the circle's boundary. If you cut a circle and straighten it, the length of the edge will be the length of the circumference. The formula for calculating perimeter is Circumference = 2πr

Where r is the radius of the circle

Area -  The area of ​​a circle is the area occupied by the circle in the two-dimensional plane. This is easily determined  using the formula

where r is the radius of the circle.

Given

We have been given that circle A of diameter 9 inches having circumference of 28.26 inches  and an area of 63.585 square inches. Circle B of diameter 5 inches having circumference of 15.70 inches, and the area of 19.625 square inches.

Find

We are asked to determine the value of pi by using circumference and area formula .

Solution

Part A :-

We will use the formula of the circumference of the circle which is given by

\(Circumference=2\pi r\)

For circle A , \(r=\frac{d}{2}=4.5\)and circumference = 28.26 inches

Putting these values in equation (1) ,

we get

\(28.26=2\pi 4.5\)

\(\pi =\frac{28.26}{9}\\ \pi =3.14\)

For circle B , \(r=\frac{d}{2} = 2.5\) and circumference = 15.70 inches

Putting these values in equation (1) , we get

\(15.70=2\pi 2.5\\\pi =\frac{15.70}{5\\} \\\pi = 3.14\)

Part B :-

We will use the formula of the area of the circle which is given by

\(Area=\pi r^{2}\)

For circle A , \(r=\frac{d}{2} = 4.5\)  and Area = 63.585 square inches

Putting these values in equation (2), we get

\(19.625=\pi (2.5)^{2} \\\pi =\frac{19.625}{6.25} \\\pi =3.14\)

Part C :-

The value of pi for both of the circle is same which is 3.14 by using circumference as well as area formula .

Therefore ,  the value of pi is constant which is equals to 3.14 .

The equation on solving by factoring method yields no solution.

In this question,

A no solution equation is also known as contradiction. This type of equation is never true, no matter what we replace the variable with. There is no value that will ever satisfy this type of equation.

The equation is -(3z+4)=6z-3(3z+2)

Solving the equation by factoring gives,

⇒ -(3z+4) = 6z-3(3z+2)

By distributive property,

⇒ -3z - 4 = 6z - 3(3z) - 3(2)

⇒ -3z - 4 = 6z - 9z - 6

⇒  -3z - 4 = -3z - 6

On rearranging the equation,

⇒ -3z + 3z = -6 + 4

⇒ 0 = -2

False: The set of all vectors of the form 1 x y where x and y range over all real numbers is a subspace of R3. True: The set of all vectors of the form 0 x y where x and y range over all real numbers is not a subspace of R3.

1) False Null space can consist of zero vector only. A null space is defined as the set of vectors 'x' in R^n that are solutions to the matrix equation A*x = 0.

2) True The number of columns can never be less than the number of rows of the matrix in order for a null space to exist, hence a 4x3 matrix may have the null space of only the zero vector.

3) True The set of all vectors of the form 1 x y where x and y range over all real numbers, is a subspace of R^3. This set contains zero vector because for x=0 and y=0, we get the vector as [0,0,0]. Hence it is a subspace of R^3.
