Answer:
The inspector's claim has strong statistical evidence.
Step-by-step explanation:
To answer this we have to perform a hypothesis test.
The inspector claimed that the actual proportion of code violations is greater than 0.07, so the null and alternative hypothesis are:
We assume a significance level of 0.05.
The sample size is 200 and the proportion of the sample is:
The standard deviation is
The z-value can be calculated as
The P-value for this z-value is P=0.00914.
This P-value is smaller than the significance level, so the effect is significant and the null hypothesis is rejected.
The inspector's claim has strong statistical evidence.
I think DB is congruent to DB by reflexive property. (Same line)
If it is =x then the line will be vertical
<u>Answer</u>
yes it does.
<u>Explanation</u>
The equation of a straight line is in the form of Y = mX + c, where m is a constant (the gradient) and c is the y-intercept.
The equation above, y= 4x +3 is the equation of a straight line.
y ∝ x
Introducing the constant of proportionality now become y = 4x. When like this the a line is a straight line from the origin but when we add 3 in the equation we have. Y = 4X + 3.
The equation remains proportional. This time the line passes through the point (0,3).
