The probability that a student chosen randomly from the class plays basketball or baseball is 0.56.
We are able to utilize the equation:
P(B or b) = P(B) + P(b) - P(B and b)
where
B speaks to playing ball
and b speaks about playing baseball.
From the given data, we have:
P(B) = 5/27 (the likelihood of playing ball)
P(b) = 12/27 (the likelihood of playing baseball)
P(B and b) = 2/27 (the likelihood of playing both sports)
Substituting these values into the equation, we get:
P(B or b) = P(B) + P(b) - P(B and b)
= 5/27 + 12/27 - 2/27
= 15/27
= 5/9
Hence, the likelihood that an understudy chosen haphazardly from the course plays ball or baseball is 5/9 or around 0.56.

FOR BRAINLIEST ANSWER, SOLVE APPLICATION USING ALGEBRA. TYPE THE EQUATION OR INEQUALITY AND PLEASE SHOW WORK. a) If the sales tax on a purchase came to $48, what was the original price (before tax) and what is the final price (after tax)? (Use 6% for the sales tax rate).
Step-by-step explanation:
before tax it would be 6/100×48=$2.88
so therefore before tax = $48-2.88=$45.12
final price after tax =$48+2.88=$50.88

E.g on how to work out
Note when the value of y is zero u get the x coordinate and when x is zero u get the y coordinate
C=2x+y=4
To get x 2x+0=4 x=2

In 1995 the usps approximated that they handled 1.8 x 10 pieces of mail. In 2010 the USPS reported that they handled 1.7 x 10 pieces how many more pieces of mail were handled in 1995 than in 2010
Answer:
1 piece of UPS
Step-by-step explanation:
Here, we want to know the difference in the number of pieces handled at the different times
In 1995, amount handled = 1.8 * 10 = 18 pieces
In 2000, amount handled = 1.7 * 10 = 17 pieces
The difference between what was handled in the year 2010 and what was handled in 1995 is 18 -17 = 1

Type the correct answer in the box. Use numerals instead of words. If necessary, use / for the fraction bar. What is the output of the function f(x) = x + 21 if the input is 4? When the input is 4, the output of f(x) = x + 21 is .
Answer:
When the input is 4, the output of f(x) = x + 21 is 25.
Step-by-step explanation:
The given function is
[tex]f(x)=x+21[/tex]
Here, x is input and f(x) is output.
We need to find the output of the given function f(x) if the input is 4.
Substitute x=4 in the given function.
[tex]f(4)=4+21[/tex]
[tex]f(4)=25[/tex]
So, the output value is 25.
When the input is 4, the output of f(x) = x + 21 is 25.

Answer:the SAS similarity theorem
Step-by-step explanation:
What is the largest integer $n$ such that $7^n$ divides $1000!$ ?
Answer:
The correct answer is
n = 3038
Step-by-step explanation:
Where we have;
We note that 1000! = An even number
Since Even × Even = even
Even × Odd = Even
Also, 7ⁿ is an Odd number since odd × odd = odd
Therefore 7ⁿ will divide 1000! with some fractions as follows;
1000! divided by 7ⁿ
When 7ⁿ = 1000!
log(7ⁿ) = log(1000!) = log(4.02×10²⁵⁶⁷)
n·log(7) = 2567.604
n = 2567.604/(log(7)) = 3038.23
Therefore, the largest integer n such that 7ⁿ divides 1000! = 3038
Which gives, 1000! ÷ 7³⁰³⁸ = 1.5733.

(fx) or y is 2 when x bigger than 3. so, 3 is not included. so you must draw straight horizontal line at y = 2 start from x = 3 to the right with empty circle first (it means 3 not included)

The probability that any postcard posted in Portugal on Monday is delivered to the UK within a week is 0.62.
The probability that any postcard posted in Portugal on Friday is delivered to the UK within a week is 0.41.
Anna is on holiday in Portugal. She posts 15 postcards to the UK on Monday.
How many of her postcards can she expect to be delivered within a week?
Answer:
She expect 9 postcards to be delivered within a week.
Step-by-step explanation:
We are given that The probability that any postcard posted in Portugal on Monday is delivered to the UK within a week is 0.62
We are also given that The probability that any postcard posted in Portugal on Friday is delivered to the UK within a week is 0.41.
Now we are supposed to find How many of her postcards can she expect to be delivered within a week if She posts 15 postcards to the UK on Monday.
So, The probability that any postcard posted in Portugal on Monday is delivered to the UK within a week =0.62
She expect no. of postcards to be delivered within a week.= [tex]15 \times 0.62[/tex]
She expect no. of postcards to be delivered within a week.=9.3
So, She expect 9 postcards to be delivered within a week.

It has the dimensions of 5 and 11. 5 x 11 = 55cm^2
Second One:
This one wont be straightforward like the first one. You need to find these sides manually.
7 + x = 11
x = 4
Then,
9 - x = 5
x = 4

Show that the angles A and B are congruent
Answer:
[tex]\angle A =\angle B =90^\circ[/tex]
Step-by-step explanation:
The diagram of the sled kite is attached below.
The central part of the kite is square.
We know by the property of a square that all its angles are congruent and equal to 90 degrees.
Therefore:
[tex]\angle A =\angle B =90^\circ[/tex]
Angles A and B are congruent.
