Answer:
1a: f(-2) means substituting -2 for x
1b: 65
I don't know the second one
The sample space in the problem is 6 girls and 7 boys. If ten players are to be chosen composing of three or four girls, then
for 3 girls:6C3 * 7C7 / 13C 10 = 0.06993
for 4 girls: 6C4 * 7C6 / 13C 10 = 0.3671
we add the two and the answer is 0.4371
5x + 4 + 2x + 5
First add the like terms.
You will get this: 7x + 9
And these can't be simplified anymore because they do not both go into the same multiple.
So your answer will be:
7x + 9
Answer and Step-by-step explanation:
THE QUESTION IS NOT FROM A QUIZ, IT IS FROM A HOMEWORK ASSIGNMENT.
<u>The unit rate is D. $4.00 per pound.</u>
This is because we see on the graph that at 1 pound of fudge, the cost is 4 dollars.
When looking at the unit rate, you want to look at y value for when x is 1.
