Greatest Common Factor of 12,18,84.
Factors of 12:1,2,3,4,6,12
Factors of 18:1,2,3,6,9,18
Factors of 84:1,2,3,4,6,7, 12,14,21,28 42,84
The Greatest Common Factor (GCF) of all those three factors is 6.
The Greatest Common Factor is the greatest Factor in all the numbers. In this set, 12,84,84, 6 is the greatest, making it the Greatest Common Factor.
Answer:
Type II error will occur when we conclude that the mean breaking strength of the cord is smaller than or equal to 250 pounds but in actual it was not true.
Step-by-step explanation:
We are given that you are considering going bungee jumping, but would only go if the mean breaking strength of the cord was greater than 250 pounds.
If the mean breaking strength of the cord is greater than 250 pounds, the bungee cord will not break.
<u><em>Let </em></u>
<u><em> = mean breaking strength of the cord</em></u>
So, Null Hypothesis,
:
250 pounds
Alternate Hypothesis,
:
> 250 pounds
Here, null hypothesis states that the mean breaking strength of the cord was smaller than or equal to 250 pounds.
On the other hand, alternate hypothesis states that the mean breaking strength of the cord was greater than 250 pounds.
Now, Type II error states the Probability of accepting null hypothesis given the fact that it was false or Probability of accepting the false hypothesis.
SO, <u>according to our question, Type II error </u>will occur when we conclude that the mean breaking strength of the cord is smaller than or equal to 250 pounds but in actual it was not true and he mean breaking strength of the cord was greater than 250 pounds.
1.86 : 2 = 186 hundredths : 2
1.86 : 2 = 93 hundredths
1.86 : 2 = 0.93
The interior angles of a parallelogram will always equal 360. The interior angles of a triangle are 180 if it is a equilateral triangle then the angles are 60 degrees each. You know 2 sides of parallelogram. The 100 degree and 90 degree. You can find the one opposing the x because it’s on a straight line and a straight line is 180 degrees if a triangle is 60 degree angle then the opposing angle to complete the straight line must be 180-60 so you get 120. You now know 3 sides. 120, 90 and 100
They should add up to be 360 so you can set up an equation like so
120+90+100+x=360
And x = 50
