Answer: 0.6934%
Step-by-step explanation:
Probability is the branch of mathematics that is concerned with the numerical descriptions of how likely an event will occur or how likely a proposition is true
If 37% of high school students said that the exercise regularly, the
probability that 5 students who are randomly selected will say thay they exercise regularly will be:
= (37/100)^5=0.006934
= 0.6934%

Answer:
y = 
Step-by-step explanation:
First, we need to rearrange the equation to make it y = mx + c
4x - y = 3
y + 3 = 4x
y = 4x -3
So the slope of the line is 4.
The slope of a line perpendicular to an equation is:

So the slope of the perpendicular line is:
= -0.25
Now to find the equation of a line you can use the following equation:
y - y₁ = m(x - x₁)
Where y₁ is the y-coordinate, x₁ is the x-coordinate and m is the gradient. Plug the values in:
y₁ = 6
x₁ = -5
m = 
y - 6 =
(x - - 5)
To get rid of the fraction we need to multiply the whole equation by 4:
4y - 24 = -1(x - - 5)
The two negatives cancel out:
4y - 24 = -1(x + 5)
Multiply the brackets out:
4y - 24 = -x + 5
Now, to rearrange the formula back into y = mx + c
Move the -24 over to the other side making it a +24:
4y = 2x + 5 + 24
4y = 2x + 29
Divide everything by 4:
y = 
y =

Answer:
laps can Fred run in one hour.
Step-by-step explanation:
Given Statement: Fred is running on the school track. He can run
laps in
of an hour.
Unit rate are expressed as a quantity of 1, such as 3 feet per second or 7 miles per hour, they are called unit rates
From the given condition we have;
In
he can run
laps
Unit rate per hour = 
=
laps
Therefore, Fred can run in one hour is,
laps.
2/3 of the journey = 6 miles
1 (whole journey ) = 6 / 2/3 = 6 * 3/2 = 9 miles answer
