Answer:
42
Step-by-step explanation:
ABC + CBD = ABD
3x+33 + 5x+13 = 70
Combine like terms
8x +46 = 70
Subtract 46 from each side
8x+46-46 = 70-46
8x = 24
Divide each side by 8
8x/8 = 24/8
x=3
We want to find ABC
ABC = 3x+33 = 3*3 +33 = 9+33 = 42
Answer:
t = 3
Step-by-step explanation:
Given
- 3 (t - 2) + 7t = 9t - 9 ← distribute left side and simplify
- 3t + 6 + 7t = 9t - 9
4t + 6 = 9t - 9 ( subtract 9t from both sides )
- 5t + 6 = - 9 ( subtract 6 from both sides )
- 5t = - 15 ( divide both sides by - 5 )
t = 3
Answer:
The probability of getting exactly 3 head=0.3125
Step-by-step explanation:
Given that probability of getting head p=0.5
So probability of getting tail q=0.5
Number of coin toss n=6
And number of trial r=3
We know that from Binomial distribution function,the probability given as follows
So now by putting the values
Now by solving this
The probability of getting exactly 3 head=0.3125
