Answer:
Slope = -1/4
Step-by-step explanation:
Slope = (-8 + 5)/(0 + 12) = -3/12 = -1/4
Answer: D. Both triangles have an obtuse angle
This is because it says "Each triangle has <u>1 obtuse angle</u> and 2 acute angles" in the instructions. An obtuse angle is any angle between 90 and 180 degrees, excluding both endpoints.
Answer:
A. Division property of inequality
Step-by-step explanation:,
If a, b and c are any real numbers,
By the division property of inequality,
a = b ⇒ 
,
By the inverse property of multiplication,
where, 1 is multiplication identity.
By the subtraction property of inequality,
a = b ⇒ a - c = b - c
By transitive property of inequality,
a = b and b = c ⇒ a = c,
Thus, it is clear that,
Division property of inequality is used in step 4.
Option A is correct.
Answer:
Yes, the test was conducted with a risk of a type I error.
Step-by-step explanation:
If we reject the null hypothesis, does this mean that we have proved it to be false beyond all doubt? Explain your answer.
Yes, for a null hypothesis to be rejected, it has being proven beyond all doubt that the null hypothesis will not work. the normal distribution has being used for the probability calculation.
if the null hypothesis is rejected and the alternative hypothesis is accepted, a type I error as occur.
In general terms:
‘a hypothesis has been rejected when it should have been accepted’. When this occurs, it is called a type I error.
