Please answer question 10
sveta [45]

Answer:

Step-by-step explanation:

1) First, we figure out the number of blue and green marbles (27 each)

2) Subtract the 6 blue and 3 green marbles. We now have 21 blue marbles and 24 green marbles.

3) Since we want to have more blue marbles while taking out the <em>minimum</em> number of green, we're going to take out green marbles out until there's one less than blue. Because there's 21 blue, we want 20 green. We've taken out 4/13 marbles so far.

4) Now, we're going to take 1 marble out of both the greens and blues until we have 17 blue and 16 green. We've now taken out 12/13 marbles. We can't make the 13th marble a blue one, otherwise we even them out, so we'll take another green. Now we have 17 blue and 15 green.

5) Count the number of greens you've taken out, and voila!

A candidate for mayor wants to know how strong her support is among voters, so she posts an online survey on her campaign websit
maks197457 [2]
1) A. Biased because the population could be uneven. Too many of one ethnicity, too many of one gender, etc. 

2) I believe this one is C. because there are not enough people. You need to survey the majority of parents instead of a selected few. 

3) There are 80 green marbles per 500, therefore calculate the percentage. \frac{80}{500}=0.16 or 16 percent. Multiply 16 percent or 0.16 times 25. It gives you 4.

4) This one is a probability thing too. For every 500 batteries, there are 3 that are defective, therefore, \frac{3}{500}= 0.006. 

0.006*12000 = 72

5) Yet another one. Add up all the nuts and you get 48. The chance of getting a cashew from these 48 is: \frac{9}{48}=0.1875. 

Therefore: 0.1875*32=6

y-------> represents the balance, in dollars, of a bank account

we know that

y=-50x+100

the rate of change is equal to the slope of the line

so

m=-50\frac{\$}{month}

therefore

<u>the answer is</u>

the rate of change is -50\frac{\$}{month}
