Answer:
The median weight for shelter A is greater than that for shelter B.
The median weight for shelter B is greater than that for shelter A.
The data for shelter A are a symmetric data set.
The data for shelter B are a symmetric data set.
The interquartile range of shelter A is greater than the interquartile range of shelter B.
Answer:
a. 0.047
b. Unlikely.
Step-by-step explanation:
a. The probability of a test result being wrong for a person not using mrijuana = 8 / 170 = 0.047.
b. As the probability for a wrong result is < 0.05 we can say that the test is unlikely to be wrong.
They are vertical angles meaning they both have the same angle thus you can set the two equations equal to each other
9y+7 = 2y+28
Solve for y
Plug your y into one of the equations and you’ll get your angle
Answer the anser is 3

Step-by-step explanation:
Answer:
The measure of the three angles are 120°, 20° and 40°
Step-by-step explanation:
Let
x ----> the measure of the first angle
y ---> the measure of the second angle (smallest angle)
z ---> the measure of the third angle
Remember that
The sum of the angles in a triangle must be equal to 180 degrees
so
----> equation A
-----> equation B
------> equation C
solve the system by substitution
substitute equation B and equation C in equation A
solve for y
<em>Find the value of x</em>
----
<em>Find the value of z</em>
---->
therefore
The measure of the three angles are 120°, 20° and 40°
