A counterexample is an example which opposes an idea. The idea that all freshman girls are going to the dance can be opposed by saying that one of them will not be going. If one out of a group does not go to the dance, then the statement that all of these girl types are going would be a false statement. Most of the freshman girls will be going, aside from one. Roberta is causing problems for this statement. You'd better tell her to straighten her act up!
Answer:

Step-by-step explanation:
Answer:
Option B:
Classification:
The hypothesis test is Two-tailed.
Step-by-step explanation:
The mean length of imprisonment for motor-vehicle theft offenders in this country is 22.1 months.
This means that the null hypothesis is that the mean is of 22.1 months, that is:
A hypothesis test is to be performed to determine whether the mean length of imprisonment for motor-vehicle theft offenders in this city differs from the national mean of 22.1 months.
At the alternate hypothesis, we test if this mean is different of 22.1, that is:
Which means that the answer is given by option b).
Which of the following is the correct classification of the hypothesis test?
We test if the mean is different from a value, which means that the hypothesis test is Two-tailed.
Answer:
r = 19 ft
Step-by-step explanation:
Circumference, C is given as 119.32 ft
Circumference of a circle is given by the formula, 2πr
This means that,
C = 2πr, we're told to assume that π = 3.14
So therefore,
119.32 = 2 * 3.14 * r
r = 119.32 / 6.28
r = 19 ft
Answer:
(-11,-4) and (-5,-7)
Step-by-step explanation:
the rule (x,y)→(x−7,y+2) means the x-value of the coordinate decreases by 7, and the y-value of the coordinate increases by two.
Apply the rule to the 1st question by plugging in the coordinates:
(x,y)→(x−7,y+2)
(−4,−6)→((-4)−7,(-6)+2)
(−4,−6)→(-11,-4)
Let's use the same process for the 2nd question:
(x,y)→(x−7,y+2)
(2,−9)→((2)−7,(-9)+2)
(2,−9)→(-5,-7)
