Since children have a population of 3000 with 150 degrees
Divide both 150 and 3000 by 150 to get 1:20
Then multiply 20 with 360 to get the total population
Total Population: 7200
And since we have the ratio of degrees to population
We multiply 20 to the others to get
Number of Men: 1800
Number of Women: 2400
The probability for each and every throw is always 1/2 independent of what has happened before.
P(6_T) = 1/2 * 1/2 * 1/2 * 1/2 * 1/2 * 1/2 = 1/64 or 0.015625
Hi there! Marcie made a mistake in the last step of the solving process.
Let's solve this problem step by step!
−2(x − 5) − 12 ≤ 4 + 6(x + 3)
First work out the parenthesis, which can for instance be done using rainbow method.
−2x + 10 − 12 ≤ 4 + 6x + 18
The parenthesis are worked out correctly. Remember that multiplying a negative by a negative gives you a positive.
Now we can collect the terms.
−2x − 2 ≤ 6x + 22
The terms are collected correctly.
Next up is subtracting 6x from both sides and adding 2 to both sides of the inequality.
−8x ≤ 24
This step is also correct.
Finally we must divide both sides of the inequality by -8 to find our answer. Be aware of the fact that the sign flips when dividing by a negative!
x ≤ −3
Mistake! Marcie forgot to flip the sign. Instead the answer should be
~ Hope this helps you!
