Hello!
The best estimate for the height of a desk is a meter. One kilometer is equal to 1,000 metres. A desk is obviously not 1,000 metres high because, well, our roofs wouldn't be that high!
Answer: 560 tickets
Step-by-step explanation:
3/4 = 420/x; now cross multiply:
3x = 4(420)
3x = 1,680; now divide both sides by 3, and you get x = 560
Answer:
x = 6
Step-by-step explanation:
3x - 1 = 17
add 1 to both sides:
3x = 18
divide by 3:
x = 6
Answer:
5^6
Step-by-step explanation:
by the law of exponents,
5^2 * 5^(-8)
5^ [2+ (-8)]
5^(2-8) = 5^-6 = 1/5^6 = 5^6
Mutually exclusive means that the intersection of the events is empty: P(S and T) = 0.
P(S or T) = P(S) + P(T) = 29% + 49% = 78%
If events S, T are not mutually exclusive, then P(S or T) = P(S) + P(T) - P(S and T)
