Step-by-step explanation:
Mid Point : A point which lies on the line segment and is equidistant from both the ends of the segment is called a mid point.
A line segment can have ONLY ONE mid point and it divides the line segment into two equal parts.
Now, Given : C is the midpoint of AB.
and B is the midpoint of CD.
⇒ AC = BC and BC = BD
Now by Euclid's Lemma
- "Things which are equal to the same thing are equal to each other."
Here, AC = BC , and BC = BD
⇒ AC = BD
Hence the result.
1000000 / 1000 = 1000
there are 1000, 1000's in 1000000

Answer:
Graph C
Step-by-step explanation:
Hi there!
The given linear equations are organized in slope-intercept form: where <em>m</em> is the slope of the line and <em>b</em> is the y-intercept, or the value of y when the line crosses the y-axis.
y = 2x + 4
Here, the <em>b</em> value is 4. Therefore, the y-intercept of this line is 4.
y = -3x - 2
Here, the <em>b</em> value is -2. Therefore, the y-intercept of this line is -2.
To identify the graph that models these equations, we just have to look for the graph where the lines cross the y-axis at 4 and -2.
The only graph that does this is graph C.
I hope this helps!
Answer:
And since the p value is lower than the significance level we have enough evidence to reject the null hypothesia and the best option is:
C. 0.0011; reject the null hypothesis
Step-by-step explanation:
For this case we have the following system of hypothesis:
Null hypothesis :
Alternative hypothesis:
In order to check this hypothesis we can use a z test for a proportion. The statistic is given by:
(1)
And the value for this case is
We are conducting a bilateral test so then the p value can be founded on this way:
And since the p value is lower than the significance level we have enough evidence to reject the null hypothesia and the best option is:
C. 0.0011; reject the null hypothesis
