Answers
Answer: number 7. 7
Step-by-step explanation:
Simplifying
7X + 1 + -5X = 15
Reorder the terms:
1 + 7X + -5X = 15
Combine like terms: 7X + -5X = 2X
1 + 2X = 15
Solving
1 + 2X = 15
Solving for variable 'X'.
Move all terms containing X to the left, all other terms to the right.
Add '-1' to each side of the equation.
1 + -1 + 2X = 15 + -1
Combine like terms: 1 + -1 = 0
0 + 2X = 15 + -1
2X = 15 + -1
Combine like terms: 15 + -1 = 14
2X = 14
Divide each side by '2'.
X = 7
Simplifying
X = 7

12
Answers
Answer:
like 2/3 or 15/16; Mixed number - like 1 1/2 or 4 5/6; Integer - like 5 or 28
Step-by-step explanation:
The required fractions for 2/3, 3/4, and 5/6 with a denominator of 12 are 8/12, 9/12, and 10/12 respectively
Given the following fractions
2/3, 3/4 and 5/6
We are to write as equivalent fractions with a denominator of
12
For the fraction 2/3;
[tex]= \frac{2}{3} \frac{4}{4}\\= \frac{2 \times 4}{3 \times 4} \\= \frac{8}{12}[/tex]
For the fraction 3/4
[tex]= \frac{3}{4} \frac{3}{3}\\= \frac{3 \times 3}{4 \times 3} \\= \frac{9}{12}[/tex]
For the fraction 5/6;
[tex]= \frac{5}{6} \frac{2}{2}\\= \frac{5 \times 2}{6 \times 2} \\= \frac{10}{12}[/tex]
Hence the required fractions for 2/3, 3/4, and 5/6 are 8/12, 9/12, and 10/12 respectively

The marked price of an article is Rs. 2200, After allowing a certain percent of disc amount from the with 13% Value Added Tax (VAT) levied, the article is sold at Rs. 2063.38. Find discount percent
Answers
To sell the article at a price of Rs. 2063.38 after applying 13% VAT, a discount of approximately 6.21% is given on the marked price of Rs. 2200.
Let's break down the given information to solve for the discount percent:
1. The marked price of the article is Rs. 2200.
2. After allowing a certain percent of discount, the article is sold at Rs. 2063.38, including 13% VAT.
Let's assume the discount percent as 'x'. We can calculate the discounted price using the formula:
Discounted Price = Marked Price - (Discount Percent/100) * Marked Price
Substituting the given values, we have:
2063.38 = 2200 - (x/100) * 2200
Now, let's solve the equation to find the value of 'x':
2063.38 = 2200 - 22x
Rearranging the equation, we have:
22x = 2200 - 2063.38
22x = 136.62
x = 136.62 / 22
x ≈ 6.21
Therefore, the discount percent is approximately 6.21%.

Some researchers postulate the frequency of colds can be dramatically reduced with regular exercise. In 2010, a group of researchers published an article related to this research question in Medical News Today. The article was based on the findings of a study by researcher David Nieman that followed 1,002 randomly selected people aged 18-85 years for 12 weeks, asking them whether they usually exercise 5 or more days per week (Yes or No) as well as having them record on a weekly basis whether they had a cold during the previous week (Yes or No).
Suppose the researcher would like to plot the data on whether the study participants usually exercised or more days per week. Which of the following would be an appropriate graph?
a. bar chart
b. a scatterplot
c. parallel boxplots
d. a single histogram

Option a (Bar Chart) is the right approach.

Even before we want to equate or compare the distinct types, a bar chart was being used, it is a set of productivity and profitability, with either the price fluctuations over a given time displayed by each bar.
We would like to compare two different groups here:
Individuals who work out five days a week or even more than that. Someone who doesn't do 5 or maybe more days of exercising.The other options offered were never relevant to the relation or condition presented. So, option b seems to be the correct one.

2. The probability of a success must remain constant in a binomial experiment.
(a) Explain why this is true.
(b) How does this relate to the requirement of independence in a binomial experiment?
Answers
Answer:
It takes about 18m
Step-by-step explanation:
An experiment is said to be binomial in nature if and only if it obeys the following conditions which include :
Fixed number of trials Each trial must be independent Only two possible outcomes Probability of success on each trial is the same.When an experiment obeys these conditions, then it can be adjudged to be a binomial experiment.
The probability of success on each trial must the same, this also allows the probability of failure to be the same throughout the experiment since there are only two possible outcomes on each trial and the outcomes are equally likely. Independence in a binomial experiment entails that, each individual trial does not depend on the result or outcome of the previous trial, since the probability of success is constant all through the experiment, then independence of each trial is a necessary prerequisite for a binomial experiment.Hence, a binomial experiment must meet the four listed requirements.

The length of the shorter leg, the longer leg, and the hypotenuse of the right-angled triangle is 15, 20, and 25, respectively.
Let the length of the longer leg of the right-angled triangle be "x".The length of the shorter leg of the right-angled triangle is x-5.The length of the hypotenuse of the right-angled triangle is x+5.We know that it is a right-angled triangle, so we apply the Pythagorean theorem.The sum of the individual squares of the base and the height of the right-angled triangle is equal to the square of the hypotenuse.x² + (x-5)² = (x+5)²x² + x² + 25 - 10x = x² + 25 + 10xx² - 20x = 0x(x-20) = 0The value of "x" can't be zero, so the value of "x" is 20.The length of the longer leg of the right-angled triangle is 20.The length of the shorter leg of the right-angled triangle is 15.The length of the hypotenuse of the right-angled triangle is 25.To learn more about triangles, visit :

Denis is currently unemployed and wants to
become the manager of Roberto's
Restaurant. To become a manager in
Roberto's Restaurant, Denis first has to serve
as a cook there. To become a cook in
Roberto's Restaurant, he first has to serve as
a waiter there.
Denis has a 60% chance of being hired as a
waiter. If he becomes a waiter, he has a 50%
chance of being promoted to cook. If he
becomes a cook, he has a 40% chance of
being promoted to manager.
At Roberto's Restaurant, managers get paid
$25 per hour, cooks get paid $15 per hour,
and waiters get paid $10 per hour. If Denis
stays unemployed, he will make $0 per hour.
What is the expected hourly payoff of
Denis's plan to seek employment at
Roberto's Restaurant?
Round your answer to the nearest cent.
Answers
The expected hourly payoff of Denis's plan to seek employment at Roberto's Restaurant is $16.50.
To calculate the expected hourly payoff of Denis's plan, we need to consider the probabilities of each step and the respective pay rates.
1. Probability of becoming a waiter: 60% (0.60)
Pay rate as a waiter: $10 per hour
2. Probability of being promoted to cook given he becomes a waiter: 50% (0.50)
Pay rate as a cook: $15 per hour
3. Probability of being promoted to manager given he becomes a cook: 40% (0.40)
Pay rate as a manager: $25 per hour
Now, let's calculate the expected hourly payoff:
Expected hourly payoff = (Probability of each step) * (Pay rate at each step)
Expected hourly payoff = (0.60 * $10) + (0.60 * 0.50 * $15) + (0.60 * 0.50 * 0.40 * $25)
Expected hourly payoff = $6 + $4.50 + $6
Expected hourly payoff = $16.50
Therefore, the expected hourly payoff of Denis's plan to seek employment at Roberto's Restaurant is $16.50.

Note how both triangles are isosceles triangles, which mean two angles will be equivalent. In the triangle with the marked angle measurement, since the total of angles in a triangle is 180, then the measurement of the unmarked angles have a sum of 180-64, which is 116. Then, as stated before, this triangle is isosceles, so the measurement of each unmarked angle is 116/2, which is 58.
Next, notice how the angle below angle x in that triangle shares a line with one of the 58 degree angles. This means that angle is 180-58, which is 122. Now, since the total of angles in a triangle is 180 and the triangle is isosceles, then angle x is (180-122)/2, which is 58/2, or 29 degrees
