First find the total of 2n by using the formula for summation:
( n(n+1))/2
Replace n with 24 and multiply the equation by 2 to get 2n:
2(24(24+1)2) = 2(24*25/2) = 2(600/2) = 600
Now find the total for -3 using the summation for a constant, which is multiplying n by the constant:
-3 x 24 = -72
Now add both summations together:
600 + -72 = 600 - 72 = 528.
The answer is 528.
Answer:
x= 1.5 Hope that helps!
Step-by-step explanation:
1. 12(5x-4.5)=36 First Divide both by 12 5x-4.5-36/12 = 3
2. 5x-4.5=3 add 4.5 to both sides
3. 5x= 3+4.5 = 7.5
4. 5x=7.5 divide both sides by 5 x=7.5/5= x=1.5
So, x=1.5 would be your answer. Can you make me Brainliest Please
Well ? Multiplied by it self would be the answer so ?=5

Answer:
0.98
Step-by-step explanation:
Work Shown:
P(A or B) = P(A) + P(B) - P(A and B)
P(A or B) = 0.13 + 0.85 - 0
P(A or B) = 0.98
Note that P(A and B) is 0. This is because we are told A and B are mutually exclusive events. This means both events cannot happen simultaneously. An example would be flipping a coin to have it land on heads and tails at the same time.
