Answer:
Step-by-step explanation:
Here is a list of possible outcomes.
Penny nickel
Heads heads
Heads tails
tails Heads
tails tails
Since there are four ways the two coins can land, the chances of getting tails - tails is 1 chance in 4.
Answer:
C : does not have statistical significance
Step-by-step explanation:
Because there is a 15% chance of getting that many girls by chance, the method - does not have statistical significance.
By this method, the percentage of girls =
or 51.15%
This type of method does not have practical significance.
The measure of the angle 2 is 133° and the measure of the angle 3 is 47°.
<h3>Classification Angles</h3>
They are a lot of classifications for angles like: complementary angles, supplementary angles, right angles, and others. See below:
- complementary angles - two angles whose the sum is equal to 90°.
- supplementary angles - two angles whose the sum is equal to 180°.
- right angles - angles whose the measure is 90°.
From the figure, it is possible to see that:
- the angles 1 and 3 are supplementary angles
- the angles 2 and 3 are supplementary angles
Therefore, if angle1 is 133°, you have:
angle_1 + angle_3 = 180
133 + angle_3 = 180
angle_3=180-133
angle_3=47°
If angle3 is 47°, you have:
angle_3 + angle_2 = 180
47+ angle_2 = 180
angle_2=180-47
angle_2=133°
