Answer: your mom

Step-by-step explanation:

The chances are that your gain will be $40 if you purchase two shares of ABC stock and no shares of XYZ stock, and if it is not $40 the gain is:

1) 50%, $0

2) 25%, $20

3) 75%, $30

4) 50%, $20

So, the option (4) 50%, $20 is the correct option.

The given question is asking what the chances are that your gain will be $40 if you purchase two shares of ABC stock and no shares of XYZ stock, and what the gain will be if it is not $40.

Mathematically, this can be broken down as follows:

There is a 50% chance that the temperature will be lower than average, in which case the stock price for ABC will increase by $20. Thus, the expected gain from investing in ABC is 50% x $20 = $10.

There is a 25% chance that the temperature will be higher than average, in which case the stock price for XYZ will increase by $20. Since you are not investing in XYZ, your expected gain from this is 0.

Therefore, the expected gain from investing in ABC and not investing in XYZ is 50% x $10 + 25% x $0 = $10 + $0 = $10.

Since you are investing in two shares of ABC stock, your expected gain is 2 x $10 = $20. Thus, there is a 50% chance that your gain will be $40, and otherwise your gain will be $20.

answer

C(9, 5) - C(6, 5) + C(3, 1) = 126 - 6 + 3 = 123

explanation

The first term, C(9, 5), represents the number of ways to select 5 restaurants out of 9, regardless of type. The second term, C(6, 5), represents the number of ways to select 5 non-seafood restaurants out of 6. To find the number of ways that at least one of the selected restaurants will serve seafood, we subtract the number of ways to select 5 non-seafood restaurants and add the number of ways to select exactly 1 seafood restaurant, represented by C(3, 1).

The result, 123, represents the number of ways that at least one of the selected restaurants will serve seafood.

The volume of the cylinder is approximately 9,558.4 cubic inches.

The volume V of a right circular cylinder is given by the formula:

V = πr^2h

where r is the radius of the circular base and h is the height of the cylinder.

In this case, the radius is 8 inches and the height is 15 inches. Substituting these values into the formula, we get:

V = π(8^2)(15)

= π(64)(15)

= 3,040π cubic inches

Therefore, the volume of the cylinder is 3,040π cubic inches. If you want an approximate value, you can use the approximation π ≈ 3.14 and calculate:

V ≈ 3,040(3.14)

≈ 9,558.4 cubic inches

So, the volume of the cylinder is approximately 9,558.4 cubic inches.

Answer:

(C) 29

Step-by-step explanation:

The expression (m + 8) - (5m + 11) simplifies to -4m - 3.

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

Subtract 5m + 11 and m + 8

To subtract (5m + 11) from (m + 8), we need to distribute the negative sign to each term inside the first set of parentheses:

(m + 8) - (5m + 11)

Open the brackets

= m + 8 - 5m - 11

Evaluate the like terms

= -4m - 3

The measure of the two greatest angles is 105° and 45°

Let the angles be 2x, 3x and 7x ...... (i)

According to the 'Angle Sum Property' of triangle,

2x + 3x + 7x = 180°

12x = 180°

x = 15°

Now, put value of x in (i)

2x = 2 × 15 = 30°

3x = 3 × 15 = 45°

7x = 7 × 15 = 105°

Equations 4 and 5 are not equivalent to any of the other equations.

The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign.

The equations that are equivalent are:

2 + x = 5

Negative 5 + x = negative 2

x + 1 = 4

Subtracting 2 from both sides, we get x = 3. Therefore, the equation is equivalent to x = 3.

Adding 5 to both sides, we get x = 3. Therefore, the equation is equivalent to x = 3.

Subtracting 1 from both sides, we get x = 3. Therefore, the equation is equivalent to x = 3.

Step-by-step explanation:

The required solution of the given expression δ = 0.0002. as of the given conditions

Functions is the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.

Here,
Given |x - 3| < δ, we want to find a value of delta such that |5x - 15| < 0.001.

Starting with the inequality |x - 3| < δ, we can substitute x = 3 + delta or x = 3 - δ. Let's consider the case x = 3 + δ,

|5x - 15| = |5(3 + δ) - 15|
            = |15 + 5δ- 15|
                = |5δ|

Now, we want |5δ| to be less than 0.001. So, we can divide both sides of the inequality by 5,

|5δ|/5 < 0.001/5

|δ| < 0.001/5

Therefore, if the delta is less than 0.001/5, we have |5x - 15| < 0.001.

Similarly, if x = 3 - delta, we have:

|5x - 15| = |5(3 - δ) - 15| = |15 - 5δ - 15| = |-5δ|

|-5δ|/5 < 0.001/5

|δ| < 0.001/5

So, if δis less than 0.001/5, then |5x - 15| < 0.001 for both x = 3 + delta and x = 3 - δ.

Therefore, if |x - 3| < 0.001/5, then |5x - 15| < 0.001.

So, δ= 0.001/5 = 0.0002.

The probability of choosing a preschooler who is a girl and prefers the color blue is 0.3 or 30%.

The total number of preschoolers who were asked about their color preference is 70. Out of these, 35 girls chose pink, 15 girls chose blue, 5 boys chose pink, and 15 boys chose blue.

To find the probability of choosing a girl who prefers blue, we need to use the formula:

Probability = (Number of favorable outcomes) / (Total number of outcomes)

Here, the favorable outcome is choosing a girl who prefers blue. We can see that 15 girls chose blue as their preferred color. Out of these, we need to choose a girl, so the total number of favorable outcomes is 15.

The total number of outcomes is the total number of preschoolers, which is 70. Out of these, the number of girls is 35+15=50. Therefore, the total number of outcomes where a girl can be chosen is 50.

Putting these values in the formula, we get:

The quotient rule is proved below.

In mathematics, the derivative of a function of a real variable measures the sensitivity to change of the function value (output value) with respect to a change in its argument (input value).

Given is the expression -

Q(x) = F(x)/G(x)

Quotient rule in calculus is a method used to find the derivative of any function given in the form of a quotient obtained from the result of the division of two differentiable functions. Mathematically, for a function f(x), we can write -

f'(x) = [u(x)/v(x)]' = [v(x) × u'(x) - u(x) × v'(x)]/[v(x)]²

Now, let f(x) = u(x) and g(x) = v(x).

Q(x) = u(x)/v(x)

Q(x) = u(x) v⁻¹(x)

Using the product rule -

Q'(x) = u'(x) v⁻¹(x) + u(x) {d/dx v⁻¹(x)}

Q'(x) = u'(x) v⁻¹(x) + u(x) (-1)(v(x)⁻²) v'(x)

Q'(x) = u'(x)/v(x) - u(x)v'(x)/v²(x)

Q'(x) = [v(x) × u'(x) - u(x) × v'(x)]/[v(x)]²

Therefore, the quotient rule is proved above.
