Describe how a statistical question yields an answer with variability. Give a example.
Answers
Explanation:
A question with variability is a question that does NOT have one definitive answer. Instead, it has a range of different answers.
A statistical question is one that can be answered by collecting data. By nature, there will be variability in that data, because no two people will necessarily respond the same way.
An example of a statistical question would be asking a classroom of students how many hours they studied that week. After collecting the data, there will be multiple answers instead of just one.

A triangle is:
either scalene, isoceles, or equilateral, and
either acute, right, or obtuse.
Question 1: The triangle is right b/c it has a right angle.
The triangle is isoceles because it has two congruent sides.
Right isoceles triangle
Question 2: The triangle is obtuse b/c it has an obtuse angle. (>90°)
The triangle is isoceles b/c it has two congruent sides.
Obtuse isoceles triangle
Question 3: All angles in a triangle add up to 180°. Let's find the 3rd angle.
180 - (80 + 60) = 180 - 140 = 40°
Congruent angles
If the angles are all different, the sides are all different and the triangle is scalene. It is also acute because all angles are <90°.
Acute scalene triangle
Question 4
An exterior angle of a triangle = the sum of its remote interior angles.
what does this mean? In this case, it means that
4x + 10 = 50 + x + 5
The reason this works: <ACD is supplementary to <ACB, so they must both add up to 180. Likewise, the angles of the triangle <ACB, <BAC, and <ABC all add up to 180. Since both = 180, we can set them equal (substitution prop)
m<ACD + m<ACB = m<ACB + m<BAC + m<ABC
subtract m<ACB from each side
m<ACD = m<BAC + m<ABC
now let's solve our equation.
4x + 10 = 50 + x + 5
4x + 10 = 55 + x
subtract x from each side
3x + 10 = 55
subtract 10 from each side
3x = 45
divide by 3
x = 15
the measure of the interior angle = (x+5)° = (15+5)° = 20°
the measure of the exterior angle = (4x+10)° = (4(15)+10)° = (60+10)° = 70°
Question 5
As we can see from the diagram...
AB = CD, AD = BC
<ABD = <BDC, <ADB = <CBD
Also obvious from the reflexive prop...
BD = BD
And because the three angles add up to 180° and we know that two of them are the same, the third must be the same as well.
<A = <C
(three points don't need specified because only one angle is possible with this vertex)
Question 6
Because the angles in a triangle add up to 180°...
m<A + m<ADB + m<ABD = 180°
We know that m<A = 60°...
60 + m<ADB + m<ABD = 180°
We know that m<DBC = 70°, and from the diagram, <ADB is cong. to <DBC.
Therefore m<ADB = 70°.
60 + 70 m<ABD = 180°
130 + m<ABD = 180°
m<ABD = 50°

Answer:
x= 40.33
Step-by-step explanation:
In geometry, alternate exterior angles are a pair of angles that are on the outer side of two parallel lines but on opposite sides of the transversal. In other words, they are the angles that are not on the same line as the parallel lines.
The alternate exterior angles are always equal in measure. This is because when a transversal intersects two parallel lines, it creates two pairs of alternate exterior angles, and each pair of angles is supplementary to each other (meaning that their measures add up to 180 degrees).
In this case:
a° = b°
Since,, the alternate exterior angles are always equal in measure.
3x+17 = 138
subtracting 17 on both sides
3x + 17-17 = 138-17
3x = 121
dividing both sides by 3.
The value of x is 40.33 which proves that r is parallel to s.
Answer:
c) 40.3
Step-by-step explanation:
According to the Alternate Exterior Angles Theorem, when two parallel lines are intersected by a transversal, the angles that are exterior to the parallel lines and on the alternate sides of the transversal are congruent.
Therefore, if lines r and s are parallel, then a° = b°.
To find the value of x that proves line r is parallel to line s, solve a° = b° for x.
Therefore, the value x that proves line r is parallel to line s is:

The probability of rolling a value of 1 or 6 for the unfair die ls 1/2
The probability of an event is given as :
P(event) = Required outcome / Total possible outcomes
Let the probability of other numbers on the die = n
Therefore, Probability of 6 = 3n
The Cummulative probability can be expressed thus since the Cummulative sun must be equal to 1 :
Other values on the die are 5 ; 1, 2, 3, 4, and 5
5n + 3n = 1
8n = 1
n = 1/8
The probability of other numbers = 1/8
Probability of 6 = 3(1/8) = 3/8
Probability of (1 or 6) = P(1) + P(6) = 1/8 + 3/8 = 4/8 = 1/2
Therefore, the probability of obtaining 1 or 6 is 0.5

Answer:
1/2.
Step-by-step explanation:
Probability totals must add up to 1.
P = probability.
If P(any number other than 6) = x, then P(6) = 3x, so
3x + 5x = 1
x = 1/8
P(6) = 3/8 and P(not 6) = 1/8
Therefore P(6 or 1) = 3/8 + 1/8 = 1/2 (answer).
