The new revenue can be calculated as R = q*p = 2,000*4 = $8,000.

R(q) is the revenue function for the school lunch program, which is given by the equation q*p, where q is the quantity and p is the price. According to Braley and Nelson's study, the city of Pittsburgh had an increase in price of school lunches. The revenue can be calculated by multiplying the quantity (q) of school lunches with the new price (p) after the increase. Therefore, the new revenue (R) can be calculated by R = q*p. As an example, if the quantity of school lunches is 2,000 and the price is increased to $4, then the new revenue can be calculated as R = q*p = 2,000*4 = $8,000.

The derivative of the function f(x) = 3x² + 2√x - 4x at x=1 is

Step-by-step explanation:

We have f(x) = 3x² + 2√x - 4x

[tex]f'(x) = \dfrac{d}{dx}\left(3x^2+2\sqrt{x}-4x\right)\\\\=\dfrac{d}{dx}\left(3x^2\right)+\dfrac{d}{dx}\left(2\sqrt{x}\right)-\dfrac{d}{dx}\left(4x\right)\\\\[/tex]

The sampling distribution is approximately normal.

What is the standard deviation?

Standard Deviation is calculated by first squaring the differences between the observations and the mean and then taking the square root of the sum of the squares of the differences divided by the number of observations - 1.

The Central Limit Theorem tells us that the sampling distribution for the population proportion is approximately normal.

The mean of the sampling distribution is equal to the true population proportion and the standard deviation of the sampling distribution is equal to the true population proportion times (1 - true population proportion) divided by the sample size.

So, the sampling distribution is approximately normal, with the true population proportion as its mean and the true population proportion times (1 - true population proportion) divided by the sample size as its standard deviation.

Hence, the sampling distribution is approximately normal.

The largest possible value for the probability of A4 is 0.2000

Since A1, A2, A3, and A4 are events from a common sample space, the sum of their probabilities must be less than or equal to 1.

So, the sum of the probabilities of the events can be expressed as:

P(A1) + P(A2) + P(A3) + P(A4) = 1

From the question, we have

P(A1) = P(A2) = P(A3) = 0.3

Also, we have that

Al and A2 occur simultaneously with a probability of 0.1

This means that the initial equation becomes

P(A1) + P(A2) - P(A1 and A2) + P(A3) + P(A4) = 1

Where

P(A1 and A2) = 0.2

So, we have

0.3 + 0.3 - 0.1 + 0.3 + P(A4) = 1

Evaluate the like terms

P(A4) = 0.2

The measure of r is 24°

The opposing angles created by the junction of two lines are known as vertically opposite angles or vertical angles. A pair of angles that are vertically opposed to one another is always equal.

Additionally, the vertical angle and its adjacent angle add up to 180° which is said to be a supplementary angle.

Here we have

3 straight lines are met at a point  

Let's name each name as l, m, and n as the given figure

From the line l  

=> ∠LOM + ∠MON + 122° = 180°  [ Pairs of Linear angles ]

=>  34° + ∠MON + 122° = 180°  

=> ∠MON = 180° - 122°- 34°

=>  ∠MON = 24°

It is in good conditions, the automobile travels at 57 mph.

Distance is the sum of an object's movements, regardless of direction. Distance can be defined as the amount of space an object has covered, regardless of its starting or ending position.

A scalar quantity known as distance measures "how much ground an object has traversed" while moving. The term "how far out of place an object is" is referred to by the vector quantity displacement, which is the object's overall change in position.

Simply draw a vector from your initial position to your destination and solve for the length of this line to determine displacement. In the case of a circular 5K path, where your beginning and ending positions are identical, your displacement is 0. Displacement in physics is denoted by s.

"A automobile moves 20 mph more slowly in heavy rain than in bright sunshine."

x - 19 = y

where "x" stands for speed in good weather and "y" stands for speed in bad weather.

"The same distance is covered by the car in two hours in the sun as it is in three hours in the rain."

2x = 3y

where "x" stands for speed in good weather and "y" stands for speed in bad weather.

The speed of the car in good weather, or "x," is what we are looking for. In the second equation, substitute the first equation's value for the variable "y."

x - 19 = y

2x = 3y

2x = 3 (x - 19)

Distribute:

2x = 3x - 57
