In a survey on internet usage , it was found that out of a total of 27 people, 16 use ADSL lines, 15 use wireless internet and 3 use neither of the two . what is the probability that a person chosen at random uses both internet connections
Answers
The probability that a person chosen at random uses both internet connections is 1/9
Total number of people = 27
Number of people who use ADSL lines = 16
Number of people who use wireless internet = 15
Number of people who use neither of the two = 3
Let the number of people who use only ADSL lines and wireless internet be denoted by A and B respectively.
Then A + B + A∩B + 3 must be equal to 27
A + B + A∩B = 24
further, we can see that
(A + A∩B) = 16
B + 16 = 24
B = 8
Also, (B + A∩B) = 15
8+ A∩B = 15
A∩B = 7
Thus, the number of people who use both internet connections = 7
Now, P(A∩B) = 7/27
= 1/9
Hence, probability that a person chosen at random uses both internet connections is 1/9.

[tex]\displaystyle \sum_{j=1}^{673} z_j = -\dfrac{20}3 \\\\ ~~~~ \implies S = \frac{19}3 - \left(-\frac{20}3\right)^2 = -\frac{343}9 \\\\ ~~~~ \implies |S| = \frac{343}9, m=343, n=9 \implies m+n = \boxed{352}[/tex]

A= B=
Answer:
Answers
The equation to represent the growth of the trees is given by
AA=32+6t and BB=20+9t and both the trees will be of equal height after 3 years.
The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions.
Equation is defined as the quality of being equal and is frequently represented by a mathematical statement with equal values on either side or by a problem requiring consideration of a number of factors.
Given that tree A is 32 inches tall and tree B is 20 inches tall.
Tree A grows 6 inches per year.
Length of the tree A after t years = 32 + 6t
Tree B grows 9 inches per year
Length of the tree B after t years = 20 + 9t
Now let us consider that both trees grows equal after a certain period of time.
If we equate both the expressions then we can form an equation to calculate the value of t.
∴ 32+6t = 20+9t
or, 6t - 9t = 20 - 32
or, -3t = -12
or, t = 4 years
The trees will be of equal length after 4 years.

A) This is true. We can use inductive reasoning to form a conjecture. A conjecture is basically a generalized guess. For example, a guess would be something like "the sum of the first n odd numbers is n^2". So 1+3 = 4, 1+3+5 = 9, 1+3+5+7 = 16, 1+3+5+7+9 = 25, and so on. Does the pattern go on forever?

In baseball, a commonly used rate is earned run average (ERA). ERA is a rate of earned runs to a constant number n of innings. In 2020, the pitcher in Example 2 had an ERA of 2.70. Find the value of n.
Answers
The value of n which is a constant representing number of innings is equal to 50.
What is ERA or earned run average ?
Earned runs without the help of passed ball, are represented by the earned run average, which is the number of earned runs a pitcher allows per nine innings.
It is given that In 2020, the pitcher had an ERA of 2.70.
A rate of earned runs to a fixed number of innings, n, which is also known as ERA.
Let's check it.
To determine a pitcher's earned run average or (ERA), multiply the runs by nine, then divide it by the number of innings pitched.
The runs earned in 2020 is 15 , let's multiply it by 9.
So , we get 15 × 9 = 135.
Now , divide it by number of innings which is 50.
So , the value of ERA will be equal to : 135 ÷ 50 = 27 which is also given in the question.
Now we will calculate the value of n.
So ,
n = (9 × Earned runs) / ERA
or
n = ( 9 × 15 ) / 2.7
n = 135 / 2.7
n = 50 innings
Therefore , value of n which is a constant representing number of innings is 50.
