PLZ HELP Due in an hour!

Mathematics
1 answer:
frosja888 [35]3 years ago
6 0

Answer:

1. No, 2. 46, 3. The amount of tails flips would be more than the amount of heads flips.

Step-by-step explanation:

1 is no because .77 and .23 are not equal to .5, so her prediction was wrong. 2 is 46 because if you double both the numbers (to get a total of 200 flips), you would get 154 tails and 46 heads. 3 is more tails than heads because that is what we have observed.

Jeff is four years less than twice his nephew's
ira [324]

Answer:

His nephew would be 11.

Step-by-step explanation:

First, you should model the word problem into an equation. This gives you the equation 18=2x-4. Then, you add 4 to both sides of the equation, getting 22=2x. Then, you divide both sides by two, which equals 11, which shows that his nephew is 11 years old. Hope this helped!

Can someone please answer this!
Rus_ich [418]

Answer:

Answer is 49

Step-by-step explanation:

Add all the ratios up you get 21 so then you divide 147 by 21 thus giving you 1 ratio = 7 respectively, and we know the ratio of the red is 7 because it's stated red, blue, and green -> 7,6,8. So then 7 * 7 = 49. And to confirm you can do (7*7)+(6*7)+(8*7) which should equal 147
