The supply curve swings left along the demand curve, raising the price of the pizza shops to close. If individuals just have a greater interest in beer, the demand curve will shift to the right, which will cause the price to rise as the supply curve is moved to the right. Apply this knowledge to the rest of the analysis.

If the price increase was modest, then the movement in supply in the pizza market must have outweighed the shift in demand. The supply shift in the pizza market must have been greater than the demand shift if the equilibrium amount of pizzas declines. The price of pizzas must have changed as a result of whichever modification happened first. If the amount of pizzas in the equilibrium market falls, the demand shift must have been greater than the supply shift.

The demand curve changes to its proper position. It happens as a result of people switching to eating pizza instead of pizzas. The new equilibrium price rises as a result of the new demand curve and the existing supply curve.

A rise in supply and a decline in demand will result in a decrease in the equilibrium price, but the impact on the equilibrium quantity cannot be predicted. Consumers now place less significance on price for any quantity, and producers are willing to simply accept a lower price; as a result, the price will decrease.

The measure of angle RQT is 63°

From the question, we are to determine the measure of angle RQT.

From the diagram,

We can observe that ∠PQS and ∠SQT form a linear pair

Thus,

∠PQS + ∠SQT = 180°

(4x + 15)° + (10x - 3)° = 180°

First, determine the value of x

4x + 15 + 10x - 3 = 180

4x + 10x = 180 - 15 + 3

14x = 168

x = 168/14

x = 12

In the diagram,

∠RQT and ∠PQS are vertically opposite

From the given information,

∠PQS = (4x + 15)°

∴ ∠RQT = (4x + 15)°

Substitute the value of x

∠RQT = (4(12) + 15)°

∠RQT = (48 + 15)°

∠RQT = 63°

Hence, the measure of angle RQT is 63°

Here we have the function:

f(x) = x² + x

Now we want to apply a translation of 4 units to the left, followed by a horizontal shrink by a factor of 1/3.

First, the translation is written as:

g(x) = f(x + 4)

The probability that the length of time will be between 50 and 70 hour is  0.4082.

Height is a simple instance of an event that describes a normal distribution: most people are of medium height, the proportions of people who are taller and shorter than average are roughly equal, and a very small (but still roughly equivalent) proportion of people either are extremely tall or extremely short.

Now, as per the given question;

Let t be the variable representing the length of time (t = 50)

As a result, the mean of the battery is 50 and the standard deviation is 15.

Thus, μ = 50 (mean) σ = 15 (standard deviation)

Now, we must calculate the probability that t is between 50 & 70.

Thus, the probability  P (50 < t < 70)

The z-value will be calculated as;

Z = (t – μ) / σ

Substitute the values,

Z = 50 – 50 / 15

Z = 0

Now, for the time; t = 70

Z = 70 – 50 / 15

Z = 1.33

Thus, the probability is;

P(50 < t < 70) = P(0 < z < 1.33)

So, the area to left of Z

= 1.33 – area to the left of z = 0

= 0.9082 – 0.5

P(50 < t < 70) = 0.4082

Therefore, the probability that the length of time will be between 50 and 70 hours is 0.4082.

Part of the question is missing where x denotes a number of games and y denotes the monetary value.

y = 50x + 300

y = 85x

Estimate Sean's business's break-even point.

Calculate the same break even point by following method;

The functions are as follows:

The functions are given as:

Cost: y = 50x + 300   ......equation 1

Revenue: y = 85x       .......equation 2

For the value at break even point;

Cost = Revenue

Thus, equating 1 and 2.

85x = 50x + 300

simplifying;

35x = 300

Dividing both sides by 35

x = 60/7

Put x = 60/7 in equation 2

y = 85 × 60/7

a / b , c / d and e / f.

We are also given that:

a / b < c / d  …(1)

c / d < e / f    …(2)

Multiply (1) and (2), we get that:

a / b × c / d < c / d × e / f
