Answer:
Step-by-step explanation:
Let x be the random variable representing the number of miles that each person walked each day for 6 months. Since it is normally distributed and the population mean and population standard deviation are known, we would apply the formula,
z = (x - µ)/σ
Where
x = sample mean
µ = population mean
σ = standard deviation
For Rueben,
µ = 5
σ = 1.1
the probability that Rueben walked more than 6.1 miles is expressed as
P(x > 6.1) = 1 - P( x ≤ 6.1)
For x = 6.1,
z = (4 - 6.1)/1.1 = - 1.91
Looking at the normal distribution table, the probability corresponding to the z score is 0.02807
P(x > 6.1) = 1 - 0.02807 = 0.97193
P(x > 6.1) = 0.97 × 100 = 97%
For Victor,
µ = 4.4
σ = 1.4
the probability that Victor walked less than 5.8 miless is expressed as
P(x < 5.8)
For x = 5.8,
z = (5.8 - 4.4)/1.4 = 1
Looking at the normal distribution table, the probability corresponding to the z score is 0.8413
P(x < 5.8) = 0.84 = 84%
Answer: (x,y) = (4/3,6)

Answer: Choice A
y=2x+3; y=-1/3x+3
==================================================
Explanation:
The left portion of the blue curve is y = 2x+3 but it is only graphed when x < 0 (we could argue that but I'll set that aside for the other portion).
The right portion is the line y = -1/3x + 3 and it's only graphed when
So we could have this piecewise function
Or we could easily swap the "or equal to" portion to move to the first part instead like this
Either way, we're involving the equations mentioned in choice A
<u>Answer:</u>
The numbers represent in a linear equation in slope-intercept form are described
<u>Solution:</u>
We have to know about what do the numbers represent in a linear equation in slope-intercept form
We know that,
In the equation of a straight line when the equation is written as "y = mx + b" is called slope intercept form
The slope is the number " m " that is multiplied on the x, and " b " is the y - intercept (that is, the point where the line crosses the vertical y-axis).
And, x, y are the coordinates set representing the points a particular line which is represented by given line equation.
Hence, numbers in slope intercept form are described
