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.

A right triangle has one leg that is 24 feet long and another that is 6 feet long what is the perimeter? A right triangle had a

natka813 [3]

In the first example we must calculate hypotenuse's length using pythagorean theorem
c^2 = a^2 + b^2 => c^2 = 24^2 + 6^2 = 576 + 36 = 612 =>
c = square root of 612 + 24.74 ft
perimeter P1 = a+b+c = 24+6+24.74= 54.74 ft
In the second example we must calculate second leg in the same manner
a^2 = c^2 - b^2 => a^2 = 15^2 - 9^2 = 225 - 81 = 144 =>
a = square root of 144 = 12
perimeter P2= 15+9+12=36 ft
Good luck !!!!

Suppose 1 in 5 (1/5) JWU students own their own car. If four students are randomly selected, what is the probability that all fo

slavikrds [6]

Answer:

1/625 = 0.0016

Step-by-step explanation:

update, oh sorry, this is about 4 picks and not 5.

so, it is 1/5⁴ = 1/625 = 0.0016

1 in 5 own their own car.

that is 20% or a chance of 1/5 = 0.2 of picking a student owning a car.

let's assume that the total number of students is large enough that each pick does not change the individual probabilities.

each event (picking a student and checking the ownership of a car) is independent and non-overlapping.

so, the probability that all 5 own a car is the chance of picking the 5th student owning a car AND all 4 previous student picks owning a car.

the probability that all 4 previous picks own a car is the chance of picking the fourth student owning a car AND all 3 previous student picks owning a car.

the probability that all 3 previous picks own a car is the chance of picking the third student owning a car AND all 2 previous student picks owning a car.

the probability that all 2 previous picks own a car is the chance of picking the second student owning a car AND the previous student pick owning a car.

the probability that the first student pick owns a car is 1/5 or 0.2

so, we have a clean

1/5×1/5×1/5×1/5×1/5 = 1/5⁵ probability = 1/3125 = 0.00032

Reflect 4, 1 in the x-axis

Marysya12 [62]

Hello there,

When you reflect a point over the x-axis the x-coordinate stays the same while the y-coordinate is its opposite.

In the given point (4,1) when it is reflected over the x-axis you would get (4, -1).

Hope I helped,

Amna
