Suppose you arrive at a bus stop and the bus arrives every 30 minutes. Given that you arrive at time at the bus stop was uniform random, find the probability that you will wait between 25 to 30 minutes.
Answer:
0.167
Step-by-step explanation:
Arrival time of the bus = 30 minutes
We have to find the probability of waiting between 25 to 30 minutes.
From this we have that,
a = 0
b = 30
The solution can be expressed as;
P(25<x<30) = (30 - 25) / (30 - 0)
P(25<x<30) = 5/30
P(25<x<30) = 0.167
0.167 is the probability of waiting between 25 minutes and 30 minutes.

Which statement is true about this radical function?
f(x)=-√(x+6)
A. As x approaches positive infinity, f(x) approaches positive infinity.
B. As x approaches negative infinity, f(x) approaches positive infinity.
C. As x approaches positive infinity, f(x) approaches negative infinity.
D. As x approaches negative infinity, f(x) approaches negative infinity.
Answer:
C
Step-by-step explanation:
As x approaches positive infinity, the negativity of f(x) increases.
you can try by putting values 5 and 10 into x and notice how f(x) approaches negative infinity
As x approaches positive infinity, f(x) approaches negative infinity , Option C is the answer.
What is a Function ?Function is a mathematical statement that links two variables m a dependent and an independent variable with each other.
It is given that
f(x) = - [tex]\rm \sqrt{x+6}[/tex]
as x----- > ∞ y ---->- ∞

Two less than 3/2 of a number X is no more than 5 1/2
Answer:
[tex]\frac{3}{2} x-2\leq 5\frac{1}{2}[/tex]
Step-by-step explanation:
[tex]\frac{3}{2} x-2\leq 5\frac{1}{2}[/tex] is the equation in symbols. First, to find 3/2 of x you must multiply them together. Then to find 2 less than that you must subtract 2 from [tex]\frac{3}{2}[/tex]x. Finally, if this is no more than 5 1/2 then the less than or equal to symbol must be used.

The revenue, cost, and profit functions for this figurine, based on price, are represented on the graph. Using the graph, which price should result in the maximum profit for the sales of this figurine?
Answer:
$34.00
Step-by-step explanation:
The solution is : Kami sold 28 large figurines.
What is simplification?Simplify simply means to make it simple. In mathematics, simply or simplification is reducing the expression/fraction/problem in a simpler form. It makes the problem easy with calculations and solving.
here, we have,
from the given information, we get,
Let x represent the number of large figurines that Kami sold.
Let y represent the number of small figurines that Kami sold.
This month kami sold 70 figurines in 2 sizes.
This means that
x + y = 70 - - - - - - - - - - 1
The large figurines sold for $12 each and the small figurines sold for $8 each. The amount of money he received from the sales of the large figurines was equal to the amount of money he received from the sales of the small figurines. This means that
12x = 8y
y = 12x/8
y = 1.5x
Substituting y = 1.5x into equation 1, it becomes
x + 1.5x = 70
2.5x = 70
x = 70/2.5
= 28
y = 1.5x
= 1.5 × 28
= 42
Hence, The solution is : Kami sold 28 large figurines.
