How many ways can a person toss a coin 15 times so that the number of heads is between 8 and 12 inclusive

Answers

Answer:

16263 ways

Step-by-step explanation:

Given that:

Number of coin tosses, n = 15

Number of heads is between 8 and 12 inclusive

For 8 heads, tails = 15 - 8 = 7

15! / (8!7!) = 6435

For 9 heads, tails = 15 - 9 = 6

15! / (9!6!) = 5005

For 10 heads, tails = 15 - 10 = 5

15! / (10!5!) = 3003

For 11 heads, tails = 15 - 11 = 4

15! / (11!4!) = 1365

For 12 heads, tails = 15 - 8 = 3

15! / (12!3!) = 455

(6435 + 5005 + 3003 + 1365 + 455) = 16,263 ways

A tree is 4.1 feet tall. It is expected to grow by 14 feet per year.
At this growth rate, how many years will it take for the tree to have a height greater than 40 feet Enter the answer in th

Answers

Answer:

3 Years.

Step-by-step explanation:

4.1 feet = Starting Height.

4.1 + 14 feet = 18.1 feet.

18.1 + 14 feet = 32.1 feet

32.1 + 14 feet = 46.1

Count the number of times you added 14 to your number.

1, 2, 3.

It would take 3 years for the tree to have a height greater than 40 feet.

Answer:

It will take 3 years.

Step-by-step explanation:

To solve, we need the equation:

4.1+14x > 40.

x represents the number of years.

Then plug in numbers till we get above 40.

4.1+14(1) > 40.

4.1+14 > 40.

16.1 > 40.(incorrect)

4.1+14(2) > 40.

4.1+28 > 40.

32.1 > 40.(incorrect)

4.1+14(3) > 40.

4.1+42 > 40.

46.1 > 40.(correct)

The answer would be - 4 over 3


The way to do it is to first make the f(x) a 0
So now the problem looks like this: 0=3x+4

Now you would move the variable to the left hand side to change the sign so it will look like this: -3x=4

Finally, divide both sides of the equation by -3 to get your final answer :)

Length of mammoth's tusk in  poster = 15.33

Step-by-step explanation:

Actual height of mammoth = 10 feet 5 inches = 126 inches

Height on the poster of mammoth = 14 inches

Actual length of mammoth's tusk = 11.5 feet = 138 inches

Length of mammoth's tusk in  poster = x

126 : 14  :: 138  : x

x * 126 = 14 * 138
