Answer: P(AB) = 3/8
Step-by-step explanation:
You simply multiply P(AuB) by P(B)
3/7 * 7/8 = 3/8
Answer:
-56
Step-by-step explanation:
Hello!
Let's create an equation to figure out what the middle integer really is.
Creating an equation:
n + (n + 1) + (n + 2) = -168 (This is true because we must account for the <em>consecutive integers </em>part.)
Simplifying:
3n + 3 = -168
Subtracting:
3n = -171
Dividing:
n = -57
Now, we plug-and-chug:
-57, -56, -54 (this is because we accounted for adding <em>positive </em>one.)
Thus, the middle integer is 
.
Check:
We can see if we are correct by adding up -57, -56, -54.
(-57) + (-56) + (-54) = -168
So we are correct!
Hope this helps!
Answer:
A
Step-by-step explanation:
Sine we can figure out side XY by using Pythagorean Theorem (A^2+B^2=C^2) and find that XY= 5, We can use Soh Cah Toa (The ways I remember to use value charts) and we know that Cosine uses Adjacent over Hypotenuse in which therefore the answer would be 5/13
Answer:
B
Step-by-step explanation:
3/r=1/y-2/x
3/r=x-2y /xy
Well, the word 'of' means multiply in mathematical terms
Problem:
So, try going with these steps if you meant this⬇
Step 1: First,24% (80) = ?
Step 2: Second, 24% over 100
▶(which can also look like ➡) 24% ÷ 100
▶Just know they both are equaling to 0.24
0.24 = .24
Step 3: Third, 0.24(80) = 19.2
▶ .24 (80) = 19.2
Anyhow, your answer would have to be (if that's what you meant ) is: 19.2
