Stephan borrowed $125 to buy an electric scooter. The function f(x) = 125 - 12.5x
can be used to represent the amount of money Stephan owes on the loan, where X is the number of weeks that Stephan pays towards the loan.

The probability that the next person will purchase exactly one costume is 0.57.

what is probability?

The area of mathematics known as probability deals with numerical descriptions of how likely it is for an event to happen or for a proposition to be true. A number between 0 and 1 is the probability of an event, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes its certainty.

Given:

146 visitors purchased no costume.

230 visitors purchased exactly one costume.

31 visitors purchased more than one costume.

So, the total number of customers are,

146 + 230 + 31 = 407

The total visitors purchased exactly one costume are 230.

So,

P(Purchase exactly one costume) = 230 / 407 = 0.5651 ≈ 0.57

Hence, the probability that the next person will purchase exactly one costume is 0.57.

let  the speed of cabin cruiser in still water be x miles/h

let  the speed of current be y miles/h

during travelling with the current, speed of cabin cruiser = (x+y) miles/h

during travelling against the current, speed of cabin cruiser =(x-y) miles/h

time taken during case 1 = [tex]\frac{45}{x+y}[/tex] =3 h  --->given

=> x+y = 45/3

after solving x+y=15   ------ (i)

time taken during case 2(against current) = [tex]\frac{45}{x-y}[/tex] =5  --->given

The answer is 13 because that is the month that both memberships will cost the same amount of money.

Step-by-step explanation:

First translate the question into equations.

Total Gym:

100+20m

Where "m" equals the amount of months

Fitness Plus Elite

35+25m

Where "m" equals the amount of months

Set the equations equal to each other and solve for m, or the amount of months it takes to get the same price for each membership.

100+20m=35+25m Subtract 35 from both sides.

65+20m=25m Subtract 20m from both sides

65=5m Divide both sides by 5

13=m Both memberships will cost the same amount of money at 13 months. You can substitute this value into the original equations to check your work.

100+20(13)=$360

35+25(13)=$360

The answer is 13 because that is the month that both memberships will cost the same amount of money.

he provider ordered lactated ringers (lr) to infuse at 75 ml/hr for the next 24 hours. 18.0 liters of lr will infuse with rate of infusion.

First, we need to determine how many milliliters of LR will be infused over 24 hours. So, we need to multiply the rate of infusion (75 mL/hr) by the number of hours (24). This will give us the total number of milliliters that will be infused. In this case, it is 75 x 24 = 1800 mL. To determine the number of liters, we need to divide this by 1000 since there are 1000 mL in 1 L. Therefore, 1800 mL/1000 = 1.8 L. We can round this number up to the tenth (one decimal place), and the answer is 18.0 L.

The measure of the angle ∠ACD will be 150°. Then the correct option is D.

The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180°.

Supplementary angle - Two angles are said to be supplementary angles if their sum is 180 degrees.

The internal angles ∠A is 33° and ∠B is 117°.

Then the measure of the internal angle ∠C is given as,

∠A + ∠B + ∠C = 180°

33° + 117° + ∠C = 180°

∠C = 30°

The angle ∠C and angle ∠ACD are supplementary angles. Then we have

∠C + ∠ACD = 180°

30° + ∠ACD = 180°

∠ACD = 150°

The measure of the angle ∠ACD will be 150°. Then the correct option is D.

Answer:

Mean, median, mode, and range are all statistical measures that are used to summarize and analyze data. Mean is the arithmetic average of a set of numbers, calculated by adding all the numbers together and dividing by the total number of values. Median is the middle value in a set of numbers, which is the value that divides the data into two equal halves. Mode is the value that occurs most frequently in a set of numbers. Range is the difference between the largest and smallest values in a set of numbers.

Mean is commonly used to calculate the average value of a set of numbers. The Median is commonly used to find the middle value in a set of numbers, especially when the data is not evenly distributed. Mode is commonly used to find the most frequent value in a set of numbers. The range is commonly used to find the difference between the largest and smallest values in a set of numbers.

All of these measures are useful for different purposes, and which measure to use will depend on the data and the question being asked. In general, mean is used when the data is evenly distributed, median is used when the data is not evenly distributed, mode is used when the data is categorical rather than numerical, and range is used to measure the spread of the data.
