The ages of commercial aircraft are normally distributed with a mean of 13.5 years and a standard deviation of 7.3 years. what p
Artist 52 [7]
Answer: The percent higher is 41.68%. If 49 planes were selected, 20 of them should be above 15 years.

To find the percent, we first need the z-score.

(15 - 13.5) / 7.3 = 0.21

Now, use a normal distribution table to find the percent above a score of 0.21. It will be 41.68%.

To find the number of 49 planes above this value, multiply 49 by 0.4168. You will have about 20.4 planes.

skelet666 [1.2K]
We know that

[volume of a <span>cylindrical paint can 1]=[area of the base]*h
so
</span>[area of the base]*h=1 gallon

if <span>the height is doubled
</span>[volume of a cylindrical paint can 2]=[area of the base]*(2*h)
[volume of a cylindrical paint can 2]=2*{[area of the base]*h)}
[volume of a cylindrical paint can 2]=2*[volume of a cylindrical paint can 1]
[volume of a cylindrical paint can 2]=2*[1 gallon]-----> 2 gallons

the answer is
<span>the capacity of the lager one is 2 gallons</span>

The scale of a room in a blueprint is 6in : 13ft. A wall in the same blueprint is 9 inches. How long is the actual wall?
Ganezh [65]

Answer:

Step-by-step explanation:

6 in to 13 ft = 9 in to x ft

6 / 13 = 9 / x.....cross multiply because this is a proportion

(6)(x) = (13)(9)

6x = 117

x = 117/6

x = 19.5 (or 19 1/2) ft <====

9966 [12]

Answer:

The lady is on the second door

Step-by-step explanation:

we have that

The sign on the first door reads "In this room there is a lady, and in the other one there is a tiger"

The sign on the second door reads "In one of these rooms, there is a lady, and in one of them there is a tiger."

so

The sign on the second door is true

The sign on the first door is true or false

Since one of these signs is true and the other is false, the sign in the first door must be false

therefore

The lady is on the second door
