Answer:
d) 330
Step-by-step explanation:
The number of ways can a dance instructor send 4 of her 11 students to summer dance program is C(11 , 4)
That is ways
by using formula
now simplification
=
after cancelling 7! and on simplification
=
after cancellation we get 330 ways
The number of ways can a dance instructor send 4 of her 11 students to summer dance program is 330
Answer:
A) By using the Pythagorean Theorem, we will see that . If we simplify it, we will find that the hypotenuse of Δ
B) approximately
Step-by-step explanation:
A) In all honesty, you don't really need to look at ΔACD at all for this one. Just use the Pythagorean Theorem (like previously stated) and solve!
***Pythagorean Theorem is
B) Here, you can also use the Pythagorean Theorem! However this time, the equation will be, .
Hope you do well on the rest of your math problems :D
