She will need 5 3/5 cups of cranberry juice to make a punch for the school if Molly uses 1 2/5 quarts of lemonade.

The ratio is the division of the two numbers.

For example, a/b, where a will be the numerator and b will be the denominator.

Proportion is the relation of a variable with another. It could be direct or inverse.

Given that,

To make the recipe,

3/4 quart of lemonade and 3 cups of cranberry juice

The ratio of cranberry juice to a quart of lemonade

⇒ 3/(3/4) = 4

To make the same recipe with 1(2/5) quarts of lemonade the ratio of cranberry juice to a quart of lemonade must be maintained.

So,

4 = cranberry juice / 1(2/5)

(5/7) × cranberry juice = 4

Cranberry juice = 28/5 ⇒ 5 (3/5).

Hence "She will need 5 3/5 cups of cranberry juice to make a punch for the school if Molly uses 1 2/5 quarts of lemonade".

Answer:

t = 60

Step-by-step explanation:

Using the rule of exponents

\((a^m)^{n}\) = \(a^{mn}\) , then

\((j^{-12}) ^{-5}\)

= \(j^{(-12(-5))}\)

= \(j^{60}\)

Then t = 60

tan(41π/36) can be written in terms of the tangent of a positive acute angle as (tan((1/9)π) + tan((37/36)π)) / (1 - tan((1/9)π)tan((37/36)π))

To express tan(41π/36) in terms of the tangent of a positive acute angle, we need to find an angle within the range of 0 to π/2 that has the same tangent value.

First, let's simplify 41π/36 to its equivalent angle within one full revolution (2π):

41π/36 = 40π/36 + π/36 = (10/9)π + (1/36)π

Now, we can rewrite the angle as:

tan(41π/36) = tan((10/9)π + (1/36)π)

Next, we'll use the tangent addition formula, which states that:

tan(A + B) = (tan(A) + tan(B)) / (1 - tan(A)tan(B))

In this case, A = (10/9)π and B = (1/36)π.

tan(41π/36) = tan((10/9)π + (1/36)π) = (tan((10/9)π) + tan((1/36)π)) / (1 - tan((10/9)π)tan((1/36)π))

Now, we need to find the tangent values of (10/9)π and (1/36)π. Since tangent has a periodicity of π, we can subtract or add multiples of π to get equivalent angles within the range of 0 to π/2.

For (10/9)π, we can subtract π to get an equivalent angle within the range:

(10/9)π - π = (1/9)π

Similarly, for (1/36)π, we can add π to get an equivalent angle:

(1/36)π + π = (37/36)π

Now, we can rewrite the expression as:

tan(41π/36) = (tan((1/9)π) + tan((37/36)π)) / (1 - tan((1/9)π)tan((37/36)π))

Since we are looking for an angle within the range of 0 to π/2, we can further simplify the expression as:

tan(41π/36) = (tan((1/9)π) + tan((37/36)π)) / (1 - tan((1/9)π)tan((37/36)π))

Therefore, tan(41π/36) can be written in terms of the tangent of a positive acute angle as the expression given above.

Answer:

The value of x is 70°

Step-by-step explanation:

Lines and Angles

We need to find the value of x that makes lines n and m parallel.

Please refer to the image below where we have added new variables to the original drawing.

If n and m were parallel, then:

y and 30° are corresponding angles, having the same measure.

w and 80° are vertical angles, having the same measure.

If the two above conditions are met, then the triangle has the angles y, w, and x. Since the sum of all internal angles of a triangle is 180°:

x + y + w = 180°

Substituting:

x + 30° + 80° = 180°

Solving for x:

x = 180° - 30° - 80°

x = 70°

The value of x is 70°

The probability that a randomly selected person is a past donor who pledged but did not contribute is 0.2 * P(A)

There are 20% past donors who pledged but did not contribute.

Let us first denote the event of selecting a past donor as A and the event of selecting someone who pledged but did not contribute as B.

There are two possibilities to be considered while selecting a person from a given population:

EITHER the person is a past donor who pledged but did not contribute

OR the person is not a past donor who pledged but did not contribute.

So, the probabilities for the above cases are:

P(A and B) and P(not A and B) respectively.

Now, as per the question,

Probability of past donors who pledged but did not contribute = 20%

or, P(B|A) = 0.2

Also, probability of past donors is not given, so we do not have any information about the complement of event A.

Hence, we cannot find P(not A).

Now, using the formula of conditional probability, we get:

P(A and B) = P(B|A) * P(A)

= 0.2 * P(A)

Similarly,

P(not A and B) = P(B|not A) * P(not A)

As we cannot find P(not A), we cannot calculate P(not A and B).

Therefore, the probability that a randomly selected person is a past donor who pledged but did not contribute is:

P(A and B) = P(B|A) * P(A)

= 0.2 * P(A)

Answer: P(B|A) * P(A) = 0.2 * P(A)

An angle coterminal with 395° within the given range is 35°.

The reference angle in the first quadrant that has the same cosine value as 330° is 30°.

To find an angle that is coterminal with 395°, we need to subtract multiples of 360° until we obtain an angle between 0° and 360°.

395° - 360° = 35°

Therefore, an angle coterminal with 395° within the given range is 35°.

Now, let's move on to the next question.

To express cos(330°) in terms of the cosine of a positive acute angle, we need to find a reference angle in the first quadrant that has the same cosine value.

Since the cosine function is positive in the first quadrant, we can use the fact that the cosine function is an even function (cos(-x) = cos(x)) to find an equivalent positive acute angle.

The reference angle in the first quadrant that has the same cosine value as 330° is 30°. Therefore, we can express cos(330°) as cos(30°).

Finally, let's address the last question.

If sin(θ) = √3 and θ is in Quadrant III, we know that sin is positive in Quadrant III. However, the value of sin(0) is 0, not √3.

Answer:

x = 16

Step-by-step explanation:

Let's assume that the number of players the team can bring to the tournament is represented by the variable "x."

Given that the total amount raised by the team is $1672.50, the cost of renting the bus is $1068.50, and the budgeted amount per player for meals is $37.75, we can write the equation to determine the number of players as follows:

Total amount raised - Cost of bus - (Budget per player * Number of players) = 0

1672.50 - 1068.50 - (37.75 * x) = 0

Now, let's solve the equation for x:

1672.50 - 1068.50 - 37.75x = 0

603 - 37.75x = 0

To isolate the variable x, let's subtract 603 from both sides of the equation:

-37.75x = -603

Now, divide both sides of the equation by -37.75:

x = -603 / -37.75

x = 16

Therefore, the team can bring approximately 16 players to the tournament.

(a) Starting with the expression Var(X)=E[(X−μ)2], we can rearrange to get E[(X−μ)2] = Var(X)+μ2. Therefore, Var(X)=E(X2)−μ2.

(c) E(Z) = E[(X-μ)/σ] = (E[X] - μ)/σ = 0.

(d) Var(Z) = Var[(X-μ)/σ] = (Var[X] - μ2)/σ2 = 1.

Rent, insurance, commissions, and other expenses could be added to the operating costs of a service-based business. Most of these expenses are regular daily expenses.

A continuing cost for maintaining a system, a business, or a product is known as an operating expense, operating expenditure, operational expenditure, operational expenditure, or OPEX.

The expense of creating or providing non-consumable pieces for the system or product is known as capital expenditure (capex).

For instance, the annual costs of paper, toner, power, and maintenance for a photocopier are opex, while the cost of the photocopier itself is capex.

Additional running costs for a service-based business could include rent, insurance, commissions, and other costs.

The majority of these costs are routine daily spending.
