The next income should be a 23% or 1.23 more the next month.

The equation of the relationship is f(200) = 0.75 * 200

From the question, we have the following parameters that can be used in our computation:

Total number of drinks = 200

Cost of each drink = 0.75

Using the above as a guide, we have the following:

f(x) = Cost of each drink * Total number of drinks

Where

f(x) = Total cost

Substitute the known values in the above equation, so, we have the following representation

f(200) = 0.75 * 200

Hence, the equation is f(200) = 0.75 * 200

Answer:

a

  \(z_t = -1.645\)

b

 We should reject the Upper  \(H_o\)

Step-by-step explanation:

From the question we are told that

   The test statistics is     \(t_s = -3.43\)

     The probability is   \(p < 0.39\)

      The level of significance is \(\alpha = 0.05\)

Now looking at the probability we can deduce that this is a left tailed test

The  second step to take is to obtain the critical value of \(\alpha\) from the critical value table  

    The value  is  

               \(t_ {\alpha } = 1.645\)

Now  since this  test is  a  left tailed test  the critical value will be

               \(z_t = -1.645\)

This because we are considering the left tail of the normal distribution curve

 Now  since the test statistics falls within the  critical values the Null hypothesis is been rejected

Step-by-step explanation:

Claude owns a store. Every year, he pays corporate tax. Option B is correct.

Claude owns a store. Every year, he pays _____.
Black space to be filled from the following option,
A. sales tax B. corporate tax C. marginal tax D. personal property tax

A corporate tax is a tax levied on the net gain of an enterprise that is taxed at the commodity level in a particular mark. Net gain for corporate tax is commonly the financial statement of net gain with transformations and may be defined in detail in the tax system of each country.

Since the store owner mostly pays the corporate tax besides there, sales tax is paid by the company owners, marginal tax is also paid by the production companies, and personal property tax is paid by any person.

Thus, Claude owns a store. Every year, he pays corporate tax. Option B is correct.

Jill's annual earnings can be calculated by multiplying her weekly pay by the number of weeks in a year: $298/week x 52 weeks/year = $15,496/year. Her earnings to date are $14,900, so she has earned an additional $596 in the current week.

Social Security is taxed at 6.2%, so the amount deducted from her pay each week is 6.2% of her gross weekly pay. That's 0.062 x $298 = $18.48.

The distance of ship from the lighthouse is 546.4 feet

The angle of elevation is an angle that is formed between the horizontal line and the line of sight. If the line of sight is upward from the horizontal line, then the angle formed is an angle of elevation.

The beacon light is 126 feet high, the angle of elevation to the beacon is 13° and the distance from light house to ship = x

These from a right angled triangle,

from trigonometry

tan 13 = 126/x

making x the subject of the equation we have

x tan 13 = 126

x = 126/tan 13

but tan 13 = 0.2308

x = 126/0.2308

x = 546.4 feet

The length of one of the sides of the square base is 6 inches.

Let's denote the length of one of the sides of the square base by "s" and the height of the pyramid by "h". Then, the surface area of the pyramid can be expressed as:

Surface area = area of square base + sum of areas of four triangular faces

Surface area = s^2 + 4(1/2)(s)(h)

We know that the surface area is 116 in^2 and the sum of the areas of the four triangular faces is 80 in^2. So we can substitute these values into the equation:

116 = s^2 + 4(1/2)(s)(h)

80 = 4(1/2)(s)(h)

We can simplify the second equation to get:

20 = (1/2)(s)(h)

We can solve for h by substituting the value of (1/2)(s)(h) from the second equation into the first equation:

116 = s^2 + 4(20)

116 = s^2 + 80

s^2 = 36

s = 6

Therefore, the length of one of the sides of the square base is 6 inches.

P(A) = 0.57 (rounded to two decimal places).

Step-by-step explanation:

The probability of selecting a red marble from the hat can be found by dividing the number of red marbles by the total number of marbles:

P(red) = number of red marbles / total number of marbles

P(red) = 20/35

We can simplify this fraction by dividing both the numerator and denominator by 5:

P(red) = 4/7

So the probability of selecting a red marble from the hat is 4/7, or approximately 0.57 when rounded to two decimal places.

Therefore, P(A) = 0.57 (rounded to two decimal places).

Answer:

To calculate 2 3/4 of 500 grams, follow these steps:

1. Convert the mixed number to an improper fraction:

2 3/4 = (2 x 4 + 3)/4 = 11/4

2. Multiply the improper fraction by 500:

11/4 x 500 = (11 x 500)/4 = 2,750/4

3. Simplify the fraction by dividing the numerator and denominator by their greatest common factor, which is 2:

2,750/4 = (2 x 1,375)/(2 x 2) = 1,375/2

Therefore, 2 3/4 of 500 grams is equal to 1,375/2 grams or 687.5 grams.

Step-by-step explanation:

Answer:

The formula for compound interest is given by:

A = P(1 + r/n)^(nt)

Where:

A = the amount of money accumulated after n years

P = the principal (initial investment)

r = the annual interest rate (as a decimal)

n = the number of times the interest is compounded per year

t = the number of years

In this case, P = $2,500, r = 0.05 (since 5% = 0.05), n = 2 (since interest is compounded semiannually), and t = 15. Substituting these values into the formula, we get:

A = 2500(1 + 0.05/2)^(2*15)

A ≈ $5,551.33

Therefore, Lyla's investment will be worth approximately $5,551.33 after 15 years if interest is compounded semiannually.

sin(θ)/cos(θ) + cos(θ)/sin(θ) = 3

Combine the fractions on the left side by rewriting them with a common denominator.

sin²(θ) / (cos(θ) sin(θ)) + cos²(θ) / (sin(θ) cos(θ)) = 3

(sin²(θ) + cos²(θ)) / (cos(θ) sin(θ)) = 3

Recall the Pythagorean identity, cos²(θ) + sin²(θ) = 1, so that

1 / (cos(θ) sin(θ)) = 3

Recall the double angle identity for sine, sin(2θ) = 2 sin(θ) cos(θ). Then

2 / sin(2θ) = 3

sin(2θ) = 2/3

Take the inverse sine of both sides and solve for θ :

2θ = arcsin(2/3) + 360° n   or   2θ = 180° - arcsin(2/3) + 360° n

(where n is any integer)

θ = 1/2 arcsin(2/3) + 180° n   or   θ = 90° - 1/2 arcsin(2/3) + 180° n

We get a total of 4 solutions between 0° and 360° from both solution sets when n = 0 and n = 1 :

θ = 1/2 arcsin(2/3) ≈ 20.905°

θ = 1/2 arcsin(2/3) + 180° ≈ 200.905°

θ = 90° - 1/2 arcsin(2/3) ≈ 69.095°

θ = 270° - 1/2 arcsin(2/3) ≈ 249.095°
