First set up equation for Raj, which is 10x + .5, .5 is the y-intercept because he got a head start of .5 hours
Ruth, 14x
10x + .5 = 14x
- .5 -.5
10x = 14x - .5
-14x -14x
-4x = -.5
/-4 /-4
x = .125 miles
So she will overtake him at more than .125 miles
I hop this is right, and hope this helps
Answer: 23
Step-by-step explanation:
Here are the solutions:
X^2 - X = 0
Factor out X
X(X - 1) = 0
Here are 2 solutions
X = 0 and X - 1 = 0, which is the same as X = 1.
The solutions are:
X = 0
X = 1.
Answer:
And we can find this probability with this difference:
And if we use the normal standard distribution or excel we got:
Step-by-step explanation:
Let X the random variable that represent the time required to construct and test a particular component of a population, and for this case we know the distribution for X is given by:
Where
and
We want to find this probability:
And the best way to solve this problem is using the normal standard distribution and the z score given by:
Using this formula we got:
And we can find this probability with this difference:
And if we use the normal standard distribution or excel we got:
