Nico works at a ticket booth at a movie theater. He sold 65 child tickets, 260 adult tickets, and 175 senior tickets to a movie

Ludmilka [50]

Answer:

52% of the tickets Nico sold to the movie were adult tickets.

Step-by-step explanation:

At a theater:

Total number of child tickets sold = 65

Total number of Adult tickets sold = 260

Total number of Senior tickets sold = 175

Now,

total number of tickets sold by Nico = Child tickets + Adult tickets + Senior tickets

= 65 + 260 + 175 = 500

So, in total Nico sold 500 tickets at the theater.

Now, $\textrm{Percentage of adult ticket sold} = \frac{\textrm{Total number of adult ticket sold }}{\textrm{Total number of tickets }} \times 100$

= $\frac{260}{500} \times 100 = 52$

or, Percentage of adult tickets sold = 52%

Hence, 52% of the tickets Nico sold to the movie were adult tickets.

Spike is not a terribly bright student. His chances of passing chemistry are 0.35; mathematics, 0.40; and both, 0.12. Are the ev

Feliz [49]

Answer:

The events "Spike passes chemistry" and "Spike passes mathematics" are not independent.

The probability that he fails both subjects = 0.37

Step-by-step explanation:

The probability of Spike passing Chemistry = P(Chemistry) = 0.35

The probability of Spike passing Mathematics = P(Mathematics) = 0.40

The probability of Spike passing both Chemistry and Mathematics = P(Chemistry,Mathematics) = 0.12

For the events "Spike passes chemistry" and "Spike passes mathematics" to be independent, P(Chemistry,Mathematics) should be equal to P(Chemistry) * P(Mathematics)

But P(Chemistry) * P(Mathematics)=0.35*0.40 =0.14

So the two events are not independent.

The Probability that he passes Chemistry or Mathematics is given by P(Chemistry) + P(Mathematics) - P(Chemistry,Mathematics)

= 0.35+0.40-0.12=0.63

So the probability that he fails both subjects is the complement of this, namely (1 - 0.63) = 0.37

The area of an 17-cm-wide rectangle is 357 cm2. What is its length? The length is cm.

netineya [11]

Given :-

The area of a rectangle is 357 cm².
It's breadth is 17cm .

To Find :-

The length of the rectangle.

Solution :-

Here the area of the rectangle is 357cm² . As we know that the area of rectangle is ,

→ Area = length * breadth

On substituting the respective values ,

→ 357 cm² = 17cm * length

→ length = 357cm²/17cm

→ length = 21cm

Hence the length of the rectangle is 21cm.

I hope this helps.
