Answer:
0.90
Step-by-step explanation:
You want the probability of either event A or event B given the Venn diagram shown.
ProbabilityThe probability of an event shown in the diagram is the ratio of counts for that event to the total of all counts in the diagram. That total is 50.
The number of counts that are not part of either event is shown as 5.
P(A or B) = 1 - P(not (A or B)) = 1 - 5/50
P(A or B) = 0.90
__
Additional comment
Using the given formula, ...
P(A or B) = (25+5)/50 +(15 +5)/50 -5/50 = (25 +15 +5)/50 = 45/50
P(A or B) = 0.90

\(\cfrac{2y}{3}-\cfrac{3}{4}=\cfrac{1}{12}\implies \stackrel{\textit{multiplying both sides by }\stackrel{LCD}{12}}{12\left( \cfrac{2y}{3}-\cfrac{3}{4} \right)=12\left( \cfrac{1}{12} \right)}\implies 8y-9=1 \\\\\\ 8y=10\implies y=\cfrac{10}{8}\implies y=\cfrac{5}{4}\)
Step 1: Add 3/4 on both sides
We get
2y/3 = 1/12+3/4
We add fractions by calculating a common denominator, adjusting the numerators accordingly and adding them. See this in action below:
12 and 4 have a common multiple in 12 which will be our common denominator. Now, 1/12 does not need to be adjusted, but 3/4 becomes 3*3 / 3*4 = 9/12.
In total 1/12 + 9/12 = 10/12
So, we have 2y/3 = 10/12
Now we multiply both sides by 3, so that the 3 will cancel out the 3 in the denominator on the left side:
2y =30/12
Now we just need to divide by 2 and get the solution:
y = 15/12 = 3*5 / 3*4 = 5/4
Therefore the final answer is A:
The solution set is {5/4}

Polynomials can be classified by the number of terms they have.
A function with only one term, for example "3x⁵" is a monomial.
If you add/subtract two monomials you determine a "binomial"
\(3x^5+2x^4\)If there are three terms (or monomials) is a "trinomial"
\(3x^5+2x^4-4x^3\)The given polynomial is
\(2x^3\)Since it has only one term, it can be classified as a "Monomial"
There are 12million children in the UK. If it took Santa 3 seconds to visit each child when delivering presents, how many hours would
Answers
The number of hours it will take Santa to visit the whole children is = 10,000hours
The total number of children in UK is = 12million
That is = 12,000,000.
It took Santa 3 seconds to visit each child. That is,
1 child = 3 seconds
Therefore 12,000,000 children = x seconds
x = 12,000,000 × 3 seconds
x = 36,000,000 seconds.
But 3,600 seconds = 1 hour
36,000,000 seconds = x
x = 36,000,000/3,600
x = 10,000 hours.
Therefore, the number of hours it will take Santa to visit the whole children is = 10,000 hours.

to know more about unitary method
https://brainly.com/question/28276953
Answer:
Step-by-step explanation
1. The total cost of the trip for all 16 families is Rs 2,16,352.
2. To find out how much each family paid, we need to divide the total cost by the number of families: Rs 2,16,352 ÷ 16.
3. When we do the division, we get the result: Rs 13,522.
Now let's check if this result is correct:
1. If each family paid Rs 13,522 for the trip, then the total cost for all 16 families would be: 16 × Rs 13,522 = Rs 2,16,352.
2. This is exactly the same as the total cost given in the problem statement.
So we have shown that each family paid **Rs 13,522** for the trip

Answers
The probability that a randomly selected student has a typing speed of less than 51 words per minute if the mean (u) is 47 words per minute and the standard deviation (o) is 4 words per minute is; 68%
How to use empirical formula in statistics?The empirical rule in statistics states that for normal distributions, 68% of observed data points will lie inside one standard deviation of the mean, 95% will fall within two standard deviations, and 99.7% will occur within three standard deviations.
The formula for z-score is;
z = (x' - μ)/σ
where;
x' is sample mean
μ is population mean
σ is standard deviation
We are given;
x' = 51
μ = 47
σ = 4
Thus;
z = (51 - 47)/4
z = 1
From empirical formula at 1 standard deviation above the means, the probability is 68%.

Answer:
94.3
Step-by-step explanation:
You want to know how to fill in the proportion associated with the question, "What is 115% of 82?"
ProportionThe diagram is intended to help you match parts of the question to parts of the proportion. The attachment shows the intended relation.
The solution is found by multiplying both sides by 82:
(x/82)·82 = (115/100)·82
x = 94.3
EquationThe question can also be written as a statement:
"what" is 115% of 82
When written as an equation, "is" means "equals", and "of" means "times":
what = 115% × 82
Of course, you can use any variable name of your choosing in place of "what". In your diagram, that is "x". And, you know how to write a percentage as a fraction or decimal, so this becomes ...
x = 115/100 × 82 = 1.15 × 82
All that remains is to evaluate this expression.
x = 1.15 × 82 = 94.3
So, the answer to the question is ...
94.3 is 115% of 82.
The scatter plot below relates the diameter of a particular species of tree, in inches, to its age, in years. The growth rate of a tree, in years per inch, is also known as the growth factor of the tree. The slope of the line of best fit in the scatter plot represents the growth rate, or factor of the tree. (3.4-3.5)
Answers
Answer: To calculate the growth factor, you would need to determine the slope of the line of best fit, which is typically calculated using linear regression. The slope represents the change in the y-variable (in this case, age) per unit change in the x-variable (in this case, diameter).
Step-by-step explanation: So if the slope of the line of best fit is, for example, 5 years per inch, then the growth factor for the tree would be 1/5 (or 0.2) inches per year. This means that for every inch of diameter growth, the tree would grow 0.2 years in age.
It's important to note that the growth factor can vary depending on the particular species of tree, environmental factors, and other variables.
