Answer:
95
Step-by-step explanation:
For this we need to find the amount of left handed boys and left handed girls. Lets go first with boys.
As there are 250 and the probability that a boy is left handed is 0.1 (or 10%) we can find the amount of left handed boys by simply the product of both numbers:
leftboys= 250 * 0.1 = 25
We can do the same for girls, as there are 350 girls with a probability of being left handed of 0.2 (or 20%) for any of them:
leftgirls = 350 * 0.2 = 70
So, the total amount of left handed people is:
letftotal = lefboys + leftgirls = 25 + 70 = 95
Answer:
x = 3
Step-by-step explanation:
Distribute the 3 to (x + 5) and -3 to (2x + 4), which gives you the equation, -3x -15 = 6 - 6x - 12. Next, you need to add the like terms, which are 6 and -12. Adding them together gets you -6, so the equation is -3x -15 = -6 - 6x. Then add the -3x to both sides and the equation becomes, -15 = -6 - 3x. Then add 6 to both sides, which gives you -9 = -3x, and divide -9 by -3 and the answer is 3.
