Answer:
The answer is 68°.
Step-by-step explanation:
Following the arc length equation:
s = r * θ where s is arc length, r is radius of the circle, and θ is the angle in radians.
12 is the Radius of the Circle and therefore solve for θ:
θ =
=
=
rad. or radians
Now, convert the radians to degrees:
= 68°
Answer:
y =
<em>x</em> + 70
or
y = 70 
(They're both the same equation, whichever one you prefer you can use!)
Answer: 92,700
Step-by-step explanation:
9,270,000 / 100 = 92,700
Answer:
That means that there´s a 0.01 of probability that the student is guessing.
Remember that the significance level is related to the strength of the evidence before rejecting the null hypothesis. The Significance level is the probability of rejecting the null hypothesis if it is true.
For example if the significance level is 0.03 it will indicate that there is a 3% of probability that students are guessing.
Lower significance levels indicate that you require stronger evidence before you will reject the null hypothesis.
So we can say that the teacher needs more evidence before rejecting the null hypothesis.
