Answer:

1/26

Step-by-step explanation:

There are 4 packs in a regular card deck. Hence, we have four 10s.

The probability of selecting a 10 is thus 4/52 = 1/13

The probability of getting the coin to land on its tail is 1/2.

The probability of getting a 10 and a tail flip = 1/2 * 1/13 = 1/26

Answer:

√7 units, √98 units

Step-by-step explanation:

Pythagorean theorem

a^2+b^2=c^2. So 9+b^2=16. So b^2=7. So b=√7

a^2+b^2=c^2. SO 49+49=c^2. So 98=c^2. So c=√98.

Evaluate 2/3+3/4 <br> 1and5/12
chubhunter [2.5K]

2/3 + 3/4 = 8/12 + 9/12 = 17/12 = 1 5/12

1 + 5/12 = 12/12 + 5/12 = 17/12 = 1 5/12

2/3 + 3/4 = 1 + 5/12

For the square with side length n, the diagonal measures:

d = \sqrt{2} *n

<h3>How to get the length of the diagonal?</h3>

The sidelength of the square is n, and we want to get the length of the diagonal d.

Notice that the diagonal is the hypotenuse of a right triangle whose catheti measure n.

Then we can use the Pythagorean theorem, which says that the square of the hypotenuse is equal to the sum of the squares of the cathetus;

d^2 = n^2 + n^2\\\\d^2 = 2n^2\\\\d = \sqrt{2n^2} \\\\d = \sqrt{2}*n

That is the length of the diagonal.

There are 500 rabbits in Lancaster on February 1st. If the amount of rabbits triples every month. Write a function that represen
Anuta_ua [19.1K]

Answer:

10,93,500.

Step-by-step explanation:

On first February total number of rabbits were 500.

Now it is given that after each month rabbit population will become triple of initial.

So, after one month rabbits will become 3×500.

After two months they will become 3^{2}×500.

Thus , after m months total number of rabbits will become 3^{m}×500.

Now,

On August 1 , 7 months will get passed from February 1 so putting m = 7 in the equation we get ,

Total number of rabbits = 3^{7}×500 = 10,93,500.
