The answer would be 2 inches.
The ratio of the model to the real figure is 1 feet to 12 feet, since 15 divided by 1.25 is 12. And since 24 inches = 2 feet, 2 divided by 12 would equal 1/6 feet, which would equals 2 inches.
Let the distance remaining after time t be x miles.
Distance traveled by Alan = (6-x) miles
Distance traveled by Soren = (8-x) miles
Time takes by the two is the same. Therefore,
(8-x)/12 = (6-x)/7 => 7(8-x) = 12(6-x) => 56-7x = 72-12x => 12x-7x = 72 -56 => 5x= 16 => x = 16/5 = 3.2 miles.
And then, time taken (t) = (8-3.2)/12 = (6-3.2)/7 = 0.4 hours
Answer: 0.38
Step-by-step explanation:
Since the variable x is represented by a standard normal distribution, the probability of x > 0.3 will be calculated thus:
P(x > 0.3)
Then, we will use a standard normal table
P(z > 0.3)
= 1 - p(z < 0.3)
= 1 - 0.62
= 0.38
Therefore, p(x > 0.3) = 0.38
The probability of x > 0.3 is 0.38.
Answer:
A fixed cost: Does not change with changes in the volume of activity within the relevant range
Step-by-step explanation:
Fixed Cost:
In economics, a fixed cost in a specified period of time does not change with respect to an increase or decrease in the production of goods or services. In contrast, the variable cost changes in proportion to changes in production of goods or services.
Examples of Fixed Cost:
Salaries, Rents, insurance payments, taxes, some utilities etc
Answer:
$1.30
Step-by-step explanation:
Let x = the cost of the pencil
Let x + .80 = the cost of the pen
Let 4(x + .80) = the cost of the binder
x + x + .80 + 4(x + .80) = 11.80
2x + .80 + 4x + 3.20 = 11.80
6x + 4.00 = 11.80
6x = 7.80
x = $1.30
x + .80 = $2.10
4(x + .80) = $8.40
