Answer:
-5p-55
Step-by-step explanation:
multiply -5 by p and -5 by 11
(1) The value of x is 25
(2) The measure of ∠CBD is 60°
Explanation:
(1) The given two angles are vertical angles. Since, vertical angles are equal, we can add the two angles to determine the value of x.
Thus, we have,
Subtracting 5x from both sides, we have
Adding 10 to both sides , we have,
Thus, the value of x is 25.
(2) It is given that the measure of ∠ABC = (x+7)° and ∠CBD = (2x+14)°
Since, these two angles are supplementary angles and supplementary angles add upto 90°
Thus, we have,
Simplifying, we get,
Thus, substituting the value of x in ∠CBD = (2x+14)° to determine its value.
Thus, the measure of ∠CBD is 60°

What question do you need help with? You have to include that!
Answer:
One of the assumptions we sometimes need to make when performing statistical inferences is that the response variable in the population has a Normal distribution. Is it possible to check that this assumption is satisfied?
Statement A is correct
Step-by-step explanation:
When performing statistical inferences, one of the assumptions often made is that the response variable in the population has a normal distribution.
Since we do not have the whole population, the above assumption cannot put to a check.
However, the t distribution is robust to modest departures from normality, thus it can be used, if there are no major outliers in the plot of the data.
Therefore, statement A is correct.
