what is Segment Addition Postulate
The segment addition postulate states that if we are given two points on a line segment, A and C, a third point B lies on the line segment AC if and only if the distances between the points meet the requirements of the equation AB + BC = AC. See Diagram 1 to gain a clearer understanding of this postulate definition.
Remember that a line segment is part of a line bound by two clear end points. It is comprised of a bunch of points between those two end points.
An easier way of stating the segment addition postulate is that if point B lies on line segment AC, then AB + BC will equal AC. That seems pretty simple, does it not?
How do confidence intervals tell you whether your results are statistically significant?.
It can be inferred that there is a statistically significant result if the confidence interval excludes the value of zero effect.
Confidence Interval;
In statistics, confidence is another word for probability. For instance, if you create a confidence interval with a 95% confidence level, you can be sure that 95 times out of 100 the estimate will fall between the upper and lower values indicated by the confidence interval.
Therefore,
The confidence level is 95% if your significance level is 0.05. The hypothesis test is statistically significant if the P value is lower than your significance (alpha) level. The findings are statistically significant if the confidence interval excludes the null hypothesis value. 0

Find the equation of the linear function g that ha g(10)=5 and that i parallel to q(r)=−19/5r6
The linear equation for g is g(r)= (19/5)r - 33.
Parallel lines have the same slope. Therefore, line g(10)=5 and line q(r)=19/5 r+6 have the same slope of 19/5.
Apply slope m=19/5, and point (r=10, g=5) to line function g, we will find the y-intercept of the linear function g :
5 = 19/5 * 10 + b
solving for b we get,
b=-33
Substitute m=19/5 and b=-33 to slope-intercept form of the g function for the linear function we are looking for:
g(r)= (19/5)r - 33
Therefore, the linear function of g is g(r)= (19/5)r - 33

The expression to represent your monthly earnings would be 4550x - 400y.
What are the linear equations in two variables?
A linear equation in two variables is one that is written in the form ax + by + c=0, where a, b, and c are real numbers and the coefficients of x and y, i.e. a and b, are not equal to zero. For example, 10x+4y = 3 and -x+5y = 2 are two-variable linear equations.
Let the number of clients signed be 'x' and the number of clients whose business lose for the company be 'y'.
For each client signed company will earn = $4300 + $250
and for every client, y, whose business you lose for the company the penalty would be = $400
So we can prepare the equation for total monthly earning as
Monthly earning = (4300 + 250)x - (400)y
= 4550x - 400y.
Hence, the expression to represent your monthly earnings would be

A circular arc has measure and is intercepted by a central angle of radians.
The radius (r) of circle is 1.91 m
Here given data :
• circular arc (s) = 5 cm
• Angel (A) = 5π/6
We know that the following formula is,
Length arc = radius × angel
=> Radius (r) = Length / angel
=> Radius (r) = 5 m / (5π /6)
=> Radius (r) = ( 5 × 6 / 5π ) m
=> Radius (r) = 6/π m
=> Radius (r) = 1.91 m

(0, -2)
(0, 3)
(3, 0)
(-2, 0)
You need to solve for y:
6x – 9y = 18
6x – 9y - 6x = 18 - 6x
– 9y = 18 - 6x
– 9y/-9 = 18/-9 - 6x/-9
y = - 2 + 2/3x
or:
y = 2/3x - 2
y-intercept is: (0 , -2)
Answer:
(0, - 2 )
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
given
6x - 9y = 18 ( subtract 6 from both sides )
- 9y = - 6x + 18 ( divide through by - 9 )

if measurements are made on four different days, find the level such that there is probability only 0.02 that the mean glucose level of four test results falls above for shelia's glucose level distribution. what is the value of ?
For the value of L = 144.48, the probability of having L greater than the mean glucose level of Shelia is 0.02.
Here it is given that Sheila's glucose level follows a normal distribution with a mean of 128 mg/dl and a standard deviation of 8 mg/dl
L is the patient's blood test level.
It is given that the probability that the mean glucose level i.e 128 mg/dl is above L is 0.02.
We need to find L
We know
P(128>L) = 0.02
or, 1 - P(128 ≤ L) = 0.02
or, P(128 ≤ L) = 0.98
We know that for any Normal distribution we find the probability by converting it to standard form and then checking the p-value.
P(X < x) = Φ[(x - μ)/σ]
where,
μ = mean
σ = standard deviation
Therefore,
Φ[(L - 128)/8] = 0.98
we see that for a Z score of 2.06,
Therefore we get
(L - 128)/8 = 2.06
or, L - 128 = 16.48
or, L = 128 + 16.48
= 144.48
Therefore, the value of L would be 144.48
