If a coin is flipped 75 times, in how many ways could there be exactly two tails?

Dimas [21]

Answer:

2775 ways

Step-by-step explanation:

We have been given the case to choose exactly two tails when flipped 75 times means $^{75}C_2$

Since, $^nC_r$ is equal to $\frac{n!}{r!\cdot(n-r)!}$

Here n =75, r=2 substituting the values we will get

$\frac{75!}{2!(75-2)!}$

$n!=n\cdot (n-1)\cdot (n-2).....1$

After simplification we will get $\frac{75\cdot 74\cdot 73!}{2!\cdot73!}$

Cancel out the common term that is 73! we will get

after more simplification we will get $\frac{75\cdot 74\cdot}{2!}$

Finally, we will get $\frac{75\cdot 74\cdot}{2}=75\cdot37=2775$

In the diagram above, suppose mz6= 115°. Explain how to find the measures of each of the other seven

dexar [7]

Angles 6 and 7 are vertical angles, not alternate interior.

The same applies to angles 4 and 1, and angles 5 and 8 as well.

Any time you have two lines cross to form an X shape, the angles that are opposite one another are considered vertical angles and are always congruent.

The values you have typed into the boxes are all correct. The other drop-down choices are correct as well. Nice work.
