Denise has incorrectly expanded the expression 5(4x − 3).
a) Write a sentence explaining how you think she reached her answer.
b) Write down the correct answer. Show all of your working.
5 (4x - 3) = 20x - 3 X
Answer: a. in the step by step explanation. b. 20x - 15
Step-by-step explanation:
I think that Denise thought that the 5 only appplied to 4x since they were closer and since she multiplied them both, she thought there would be no use of it.
Example - 2 (3x+2)
2 x 3x = 6x
6x + 2
Of course this is wrong since the real answer should be 6x + 12 but someoneone like Denise may see it that way, only multiplying the ones closest and not opening it fully.
What is the probability of flipping 5 coins on the same side, that is getting either all heads or all tails? give the exact decimal answer without rounding.
Answer:
Each coin has 2 outcomes when flipping (it may be head or tail), so the possibility to flip head is equal to possibility to flip tail and is .
If you are flipping three times, then using the product rule you can conclude that the possibility to get three heads is equal to possibility to get three tails and is:

Noah ordered a meal delivery from a local restaurant. the cost of his meal, before tax, was $15.20. if the sales tax is 6.5%, what was the total cost of his meal? show or explain your thinking.
The total cost of the meal was $16.189.
What is the sales tax?
A sales tax is a consumption tax that is added to the price of goods and services. It is usually a percentage of the purchase price, and the percentage varies depending on the location and type of product or service.
We are trying to find the total cost of the meal including the sales tax. To do this, we need to calculate the amount of tax and add it to the cost of the meal.
The cost of the meal before tax is $15.20 and the sales tax rate is 6.5%. To find the amount of sales tax, we can multiply the cost of the meal by the sales tax rate as a decimal.
$15.20 x 0.065 = $0.989
The amount of sales tax is $0.989.
To find the total cost of the meal, we can add the amount of sales tax to the cost of the meal before tax.
$15.20 + $0.989 = $16.189
Hence, The total cost of the meal was $16.189.

4 if the mixing ratio of a sample of air is 2 grams/kilogram, and the temperature of the sample is 25 degrees celsius, yielding a saturation mixing ratio of 20 grams/kilogram, what is the relative humidity of the sample?
Because the temperature is greater, the relative humidity of the atmosphere is higher.
Relative humidity: What is it?Water vapor is also measured by relative humidity (RH), which is stated as a percentage but RELATIVE to the air's temperature. In plenty of other terms, it is a comparison between the quantity of water vapor that is really present in the air and the maximum amount water vapor that is possible for the air at the current temperature.

Putting the customer first, balancing efficiency and customer satisfaction (experience), and focusing on employee engagement are three key strategies for improving contact center service quality.
Productivity:
Productivity is the efficiency with which goods and services are produced and is represented by a scale. A measure of productivity is often expressed as a ratio of total output to a single input or total input in a production process. Typically the output per unit of input over a period of time. The most common example is a measure of (aggregate) labor productivity, an example of which is GDP per worker. There are various definitions of productivity (including those not defined by the ratio of outputs to inputs), and the choice depends on the purpose of measuring productivity and the availability of data gain. The main reason for differences in different measures of productivity usually has to do with how outputs and inputs are aggregated (directly or indirectly) to obtain such relative measures of productivity doing conduct.

If 29% of patients actually carry the virus, what's the probability that a patient testing negative is truly free of the virus?
If a study concluded that among people with a certain virus, 99.2% of tests conducted were (correctly) positive, while for people without the virus, 98.1% of the tests were (correctly) negative. the probability that a patient testing negative is truly free of the virus is 0.9967.
How to find the probability?Probability (testing negative is truly free of the virus) = (1- 0.29) (0.981) / (0.29) (1- 0.992) + (1- 0.29) (0.981)
Probability (testing negative is truly free of the virus) = (0.71) (0.981) / (0.29) (0.008) + (0.71) (0.981)
Probability (testing negative is truly free of the virus) = 0.69651 / 0.00232 + 0.69651

An online music store charges $1.50 for each song after you pay a $18 subscription fee. write a function that represents the arithmetic sequence. how many songs can you buy if you have $50 to spend?
The answer of 21 tracks is accurate since, once the membership cost has been paid, the store charges $1.50 by each song. Since the monthly charge is a one-time expense, it is deducted from the $50 price cap.
What are the different sorts of function?The characteristic that every input is associated to approximately one output defines a function as a relationship between a series of inputs but a set of allowable outputs. A mapping from Here to there B will only be a function if every piece in set A has one end and only the image in set B. Let A & B have been any two non-empty sets.
The number of songs that may be downloaded with the specified budget is then calculated by dividing the remaining balance by the price of each song. The outcome is an analytic sequence because each song's price is set. The outcome is then rounded down to the closest whole number, which in this example is 21.
1. Take the $50 budget and deduct the $18 membership fee:
$50 - $18 = $32
2. Take the leftover amount and divide it by the price of each song:
$32 ÷ $1.50 = 21.33
3. To the nearest full number, round down:
21 songs

What is probability?
Simply put, probability is the likelihood that something will occur. When we don't know how an event will turn out, we can discuss the likelihood or likelihood of several outcomes. Statistics is the study of events that follow a probability distribution.
By simply dividing the favorable number of possibilities by the entire number of possible outcomes, the probability of an occurrence can be determined using the probability formula.
The probability is computed by dividing the total number of possible outcomes by the number of possible ways the event could occur. Probability and odds are two distinct ideas. Odds are calculated by dividing the likelihood of an event by the likelihood that it won't.
Expected = ∑ value * probability
= $1*0.01 + 2.(0.09) + 3(0.081) + 4(0.0729)

Answer:
James is 18 and Patrick is 38
Step-by-step explanation:
Let p = Patrick's age
Let j= James' age
p = j + 20
p + 2 = 2(j+2) Substitute j + 20 for p
j + 20 + 2 = 2j + 4 Combine like terms.
j + 22 = 2j + 4 Subtract j from both sides
j -j + 22 = 2j - j + 4
22 = j + 4 Subtract 4 from both sides
22 - 4 = j + 4 - 4
18 = j
James is 18 years old.
Substitute 18 for j in p = j + 20
p = 18 + 20
p = 38

on an old-fashioned bicycle the front wheel has a radius of 2.5 feet and the back wheel has a radius of 4 inches. if there is no slippage, how many revolutions will the back wheel make while the front wheel makes 100 revolutions?
Therefore , the solution of the given problem of circle comes out to be 100 rotations of the front tire will be made by the back wheel.
What does a circle represent?Each point in the plane whose distance from that other point is a certain value forms a circle (center). It is therefore a curve composed of vertices that are spaced apart from one another in the plane by a specific amount. Furthermore, it is symmetrical about the center at all angles in terms of rotation. The closed, two-dimensional plane of a circle has all pairs of endpoints equally separated from the "center." When a line is drawn through the circle, a circle symmetry line is created. Furthermore, it rotates equally from all angles about the center.
Here,
The circle of the rear wheel is equal to circle = diameter x π, or 2.5 feet by 12 inches, or 30 inches.
The length of the front axle is 30 x 2 = 60 inches.
The diameter of the front wheel, C, is equal to 60 x Pi, or 60π, in inches.
The diameter of a back wheel is 4 x 2 = 8 inches.
The circumference of back wheel is C = 8 x Pi = 8π in inches.
750 revolutions are equal to
100 × [60Pi/8π] = 6,000π/8π.
100 rotations of the front tire will be made by the back wheel.
