Answer is 4/2 hope it helps you
The information we've been given is:
12 heads
15 tails
From those, we find that there are 12 + 15 = 27 coins.
Let's examine these ratios as such:
- 12 heads to 27 coins -
There are indeed 12 heads and 27 coins, so this comparison agrees with our data.
- 15 tails to 12 heads -
Again, nothing here contradicts with our data, so this would be correct as well
- 12 heads to 15 tails -
Simply a reversed version of the ratio above; still a completely valid way to compare the relative quantities of heads and tails
- 5 tails to 9 coins -
This one needs a little more examination. We observe that the ratio of tails to coins with our given data is 15 tails to 27 coins. This seems to go against our data, but we can simplify our ratio by dividing both the number of tails and the number of coins by 3, which indeed gives us the ratio 5 tails to 9 coins.
So, all of the given ratios are correct.
10% tax of $35 is $3.50
total price is T=35+3.50=38.50
Answer:
x = -7
Step-by-step explanation:
4 - 2(x - 3) = 24
Subtract 4 from each side
4-4 - 2(x - 3) = 24-4
-2(x-3) = 20
Divide each side by -2
-2(x-3)/-2 = 20/-2
x-3 = -10
Add 3 to each side
x-3+3 = -10+3
x = -7

Yes
<span>
Assuming that a probability
distribution is described, find its mean and standard deviation.
</span>
The mean is equal to 0.6. The standard deviation is equal to 1.5

Is it unusual for a car to have
more than one bumper sticker? Explain.
</span>
No, because the probability of
having more than one bumper sticker is equal to 0.120 that is greater that 0.05
