Answer:
13 / 30
Step-by-step explanation:
The probability an be represented by the number of desirable outcomes over the total outcomes. We know the total is 30 since there are 30 students to be chose from. Now, we need to find the number of students who play basketball and baseball. We can add the two values we are given:
7 + 11 = 18 students
BUT.... we are over-counting the students who play both. We need to subtract those 5 students, since the are counted twice, and that way, they will only be counted once:
18 - 5 = 13 students
Using the formula for probability at the top, we get:
13 / 30
Circumference c=2(pie)r
C=2(pie)5
C=31.42
Yeah, Katie sometimes delete mines too. But till date, I haven't posted something which is bad
It takes some trial and error
To find the factored form, you know that the format will look like
(x^n +/- a) (x^n +/- b)
Since the expanded form has x^4, the first part of each expression in parentheses will be x^2 because x^2 * x^2 will give you x^4
Then you have to figure out, how will you get -9 in the expanded form? The "a" and "b" parts of each expression will have to multiply to equal -9.
Factors of -9 will be -3*3 or -1*9 or -9*1
Also, consider the 8x^2 part - as it relates to finding the factors of 9. The parts of the expression that result in 8x^2 in the expanded form ...
a*x^2 + b*x^2 = 8x^2
If you think about this, you know the a and b will = -1 and 9 because you also have to add the expressions with x^2 to get 8x^2, and 3 and 3 would not give you the 8x^2 and neither would nor would -9 and 1.
Final factored form is
(x^2 - 1) (x^2 + 9)
Answer:
1/2
Step-by-step explanation:
Okay so the find slope you have the put the line in y-mx+b form. In -2x+4y=16 to get 'y' by its slef you have to add 2y to each side. 4y=16+2x then you have to divide by 4 to get y alone. y=4+1/2x
Your slope is 1/2
