The probability that at least 4 accounting majors are on the committee is P(at least 4 accounting majors) = 1 - P(less than 4 accounting majors)

We can use the complement rule to solve this problem. The complement rule states that the probability of an event happening plus the probability of the event not happening is equal to 1.

In this case, we can find the probability that less than 4 accounting majors are on the committee and then subtract that from 1 to find the probability that at least 4 accounting majors are on the committee.

There are 6 accounting majors and 9 finance majors, for a total of 15 students.

To find the probability that fewer than 4 accounting majors are on the committee, we can use the binomial probability formula:

P(k) = (combination(8,k)) [tex]\times (6/15)^k \times (9/15)^{(8-k)[/tex]

where k is the number of accounting majors on the committee.

To find the probability that fewer than 4 accounting majors are on the committee, we need to sum the probabilities for k = 0, 1, 2, and 3.

P(less than 4 accounting majors) = P(0) + P(1) + P(2) + P(3)

Finally, we can use the complement rule to find the probability that at least 4 accounting majors are on the committee:

P(at least 4 accounting majors) = 1 - P(less than 4 accounting majors)

You can calculate the exact probability using the binomial coefficient and the binomial probability formula and then subtract that from 1 to get the final probability.

Answer: 25°F is approximately $375.

Step-by-step explanation:

The scatter plot shows a positive correlation between the average monthly temperature (x) and the family's monthly heating cost (y). The line of best fit appears to be a linear equation, and it can be approximated by the equation y = mx + b, where m is the slope and b is the y-intercept.

(a) One possible equation of the line of best fit for the data is y = 15x + 300. This equation is only an approximation as it is hard to determine the exact line of best fit without more data points.

(b) Using the equation y = 15x + 300, the predicted monthly heating cost for a month with an average temperature of 25°F can be found by plugging in x = 25 into the equation.

y = 15(25) + 300 = 375

Therefore, the predicted monthly heating cost for a month with an average temperature of 25°F is approximately $375.

Step-by-step explanation:

As a result, the rectangle's sides measure 5x = 5(6.375) = 31.875 inches and 3x+5 = 3(6.375) + 5 = 20.125 inches, respectively.

We may utilize the knowledge that the rectangle's perimeter is 112 and that its sides are 5x and 3x+5 to determine the value of x and the lengths of each side. We can put up the following equation because the perimeter of a rectangle is equal to the sum of its four sides:

2(5x) + 2(3x + 5) = 112

We must simplify and account for x in order to solve for x. We'll start by allocating the two on the left side of the equation:

10x + 6x + 10 = 112

We'll then mix similar terms:

16x + 10 = 112

To get x alone, we will now deduct 10 from both sides, giving us 16x = 102.

Next, multiply both sides by 16 times to get 6.375.

Therefore as a result, the rectangle's sides measure 5x = 5(6.375) = 31.875 inches and 3x+5 = 3(6.375) + 5 = 20.125 inches, respectively.

Step-by-step explanation:

Differentiation is an algebraic process that finds the gradient (slope) of a curve.

At a point, the gradient of a curve is the same as the gradient of the tangent line to the curve at that point.

Given function:

[tex]y=4+2x-x^2[/tex]

Differentiate the given function:

[tex]\implies \dfrac{\text{d}y}{\text{d}x}=2-2x[/tex]

If the tangent to the parabola forms an angle of 45° with the negative direction of the x-axis, then the gradient of the tangent is 1.

Set the differentiated function to 1 to find the x-value of the point where the gradient of the tangent is 1:

[tex]\implies \dfrac{\text{d}y}{\text{d}x}=1[/tex]

[tex]\implies 2-2x=1[/tex]

[tex]\implies -2x=-1[/tex]

[tex]\implies x=\dfrac{1}{2}[/tex]

Substitute x = 1/2 into the given function to find the y-value of the point:

[tex]\implies y=4+2\left(\dfrac{1}{2}\right)-\left(\dfrac{1}{2}\right)^2=\dfrac{19}{4}[/tex]

Therefore, the point at which the tangent of the parabola forms an angle of 45° with the negative direction of the x-axis is:

Substitute the found point and slope into the point-slope formula to create an equation of the tangent:

[tex]\implies y-y_1=m(x-x_1)[/tex]

[tex]\implies y-\dfrac{19}{4}=1\left(x-\dfrac{1}{2}\right)[/tex]

[tex]\implies y=x+\dfrac{17}{4}[/tex]

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

Given function:

[tex]y=4+2x-x^2[/tex]

Differentiate the given function:

[tex]\implies \dfrac{\text{d}y}{\text{d}x}=2-2x[/tex]

If the tangent to the parabola is parallel to the line y = 2x - 4 then the gradient of the tangent is 2 (since parallel lines have the same gradient).

Set the differentiated function to 2 to find the x-value of the point where the gradient of the tangent is 2:

[tex]\implies \dfrac{\text{d}y}{\text{d}x}=2[/tex]

[tex]\implies 2-2x=2[/tex]

[tex]\implies -2x=0[/tex]

[tex]\implies x=0[/tex]

Substitute x = 0 into the given function to find the y-value of the point:

[tex]\implies y=4+2\left(0\right)-\left(0\right)^2=4[/tex]

Therefore, the point at which the tangent of the parabola is parallel to the line y = 2x - 4 is:

Substitute the found point and slope into the point-slope formula to create an equation of the tangent:

[tex]\implies y-y_1=m(x-x_1)[/tex]

[tex]\implies y-4=2\left(x-0\right)[/tex]

[tex]\implies y=2x+4[/tex]

Answer:

1/5 of a minute they are equal.

The cost would be $18

Step-by-step explanation:

Something does not look right.  You would not have 3 variables.

Set the two equations equal to each other and solve for m.  I think that the variables t may be an error.

30m + 12 = 15m + 15  Subtract 15 m from both sides

30m -15 m + 12 = 15m -15m + 15

15m + 12 = 15  Subtract 12 from both sides

15m + 12 - 12 = 15 - 12

15m = 3  Divide both sides by 15

[tex]\frac{15m}{15}[/tex] = [tex]\frac{3}{15}[/tex]

m = [tex]\frac{1}{5}[/tex]

Cost:

y = 30m + 12

y = 30(1/5) + 12

y = 18

y = 15m + 15

y = 15(1/5) + 15

y = 3 + 15

y = 18

We need 166.5 ml of soy sauce when we have 111 ml of vinegar.

We need 74 ml of vinegar when we have 111 ml of soy sauce.

Step-by-step explanation:

I think that you meant 150 and not 150150150 and 100 and not 100100100

[tex]\frac{soy sauce}{vinegar}[/tex] = [tex]\frac{soy sauce}{vinegar}[/tex]

[tex]\frac{150}{100}[/tex] is the same as [tex]\frac{3}{2}[/tex]  (simplified by dividing the top and the bottom by 50)

[tex]\frac{3}{2}[/tex] = [tex]\frac{x}{111}[/tex]  Cross multiply and solve for x

2x = 3(111)

2x = 333  Divide both sides by 2

[tex]\frac{2x}{2}[/tex] = [tex]\frac{333}{2}[/tex]

x = 166.5

We need 166.5 ml of soy sauce when we have 111 ml of vinegar.

[tex]\frac{3}{2}[/tex] = [tex]\frac{111}{x}[/tex]  Cross multiply and solve for x

3x = 2(111)

3x = 222  Divide both sides by 3

[tex]\frac{3x}{3}[/tex] = [tex]\frac{222}{3}[/tex]

x = 74

We need 74 ml of vinegar when we have 111 ml of soy sauce.

Answer:

We can use the trigonometric function sine to calculate the length of AB in a right-angled triangle.

The sine function relates the ratio of the side opposite an angle (in this case, AB) to the hypotenuse (AC) with the angle in question (in this case, angle C):

sin(C) = AB/AC

In this case, we know that angle C is 29 degrees and the hypotenuse AC is 5cm, so we can substitute these values into the equation to find AB:

sin(29) = AB/5

To solve for AB, we can multiply both sides of the equation by 5:

AB = 5sin(29)

AB=2.42cm

What is Function?

A relation between a collection of inputs and outputs is known as a function. In plain English, a function is an association between inputs in which each input is connected to precisely one output. A domain, codomain, or range exists for every function.

The periods where a function is above the x-axis are considered its positive regions. Where the y-values are positive is where it is (not zero). Periods where a function is below the x-axis are referred to as its negative regions. This is the case when the y-values are negative (not zero).

The graph extends to infinity from the origin above x-axis
