Answer:

Since, the equation of a line passes through (x_1, y_1) with slope m is,

y-y_1=m(x-x_1)

Thus, the equation of line passes through (4, 3) with slope \frac{1}{2} is,

y-3=\frac{1}{2}(x-4)

2y - 6 = x - 4

x-2y = -6 + 4

x-2y = -2

If x = 0,

-2y=-2\implies y =1

Thus, the line intersects y-axis at (0, 1),

If y = 0,

x-2(0) = -2\implies x = - 2

Thus, the line intersects x-axis at (-2, 0),

By joining the points (0, 1) and (-2, 0) we get the graph of the given line ( shown below )

Answer: The graph is attached.

Step-by-step explanation:

The equation of the line in Slope-Intercept form is:

y=mx+b

Where "m" is the slope and "b" is the y-intercept.

We can find "b" substituting the slope and coordinates of the (4,3) into thte equation  y=mx+b, and then solving for "b":

3=\frac{1}{2}(4)+b\\\\3-2=b\\\\b=1

By definition, the line intersects the x-axis when "y" is zero.

Then, we need to substitute the y-intercept and y=0 into  y=mx+b and then solve for "x" in order to find the x-intercept:

0=\frac{1}{2}x+1\\\\-1(2)=x\\\\x=-2

Knowing the x-intercept and the y-intercept, we can graph the line (The graph is attached)

Can a triangle with the angles of 0, 90 , and 90 be considered a triangle?
asambeis [7]

A "triangle" with the angles 0, 90, and 90 degrees cannot be considered a triangle since the two 90 degree angles make a right angle, and 0 degrees would mean a flat line. Rather it would resemble something like a straight U that is stretched sideways.

For the 405 highway that car pass through a checkpoint, assume the speeds are normally distributed such that μ= 61 miles per hou
Strike441 [17]

Answer:

Z = 1

Step-by-step explanation:

Z - score

In a set with mean \mu and standard deviation \sigma, the zscore of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

\mu = 61, \sigma = 4

Calculate the Z value for the next car that passes through the checkpoint will be traveling slower than 65 miles per hour.

This is Z when X = 65. So

Z = \frac{X - \mu}{\sigma}

Z = \frac{65 - 61}{4}

Z = 1
