The value of m must be 4 and the value of b must NOT be -3.
No matter what numbers they involve, two equations with the SAME slope (m) and a DIFFERENT y-intercept (b) have no solution. This is because they form parallel lines, never crossing and therefore never giving a solution.
Answer:
0.11069
Step-by-step explanation:
We will assume that the trains pass by his house following a uniform distribution with values between 0 and 24. The probability of a train passing on a 9-hour time period is 9/24 = 3/8 = 0.375. Lets call Y the amount of trains passing by his house during that 9-hour period. Y follows a Binomail distribution with parameters 22 and 0.375.
P(Y ≤ 5) = P(Y = 0) + P(Y=1) + P(Y=2) + P(Y=3) + P(Y=4) + P(Y=5) =

I hope that works for you!
Answer:
Page number 74
Step-by-step explanation:
Let
x ---> the number of days
y ---> the number of pages read
we know that
The linear equation in slope intercept form is equal to

where
m is the slope
b is the y-intercept
we have
<em>Anne</em>
The slope is equal to

The y-intercept is equal to

substitute
----> equation A
<em>Willow</em>
The slope is equal to

The y-intercept is equal to

substitute
----> equation B
equate equation A and equation B

solve for x

Find the value of y
substitute the value of x in equation A or equation B
equation A

equation B

Answer:
group A.)220/330
group B.)339/509
Step-by-step explanation:
2/3 of 330 is 220 therefore the people selected in group a to win $100 fuel cards will be 220/330
same thing for group B. 2/3 of 509 is 339 so the answer will be 339/509
