Answer:
Becky completed the proof incorrectly.
Step-by-step explanation:
The only difference of the two proofs, at least what I can see, is the reason for step 2. Angie claims that it is the Definition of Supplementary Angles, while Becky claims Angle Addition Postulate.
The Definition of Supplementary Angles states that m∠A + m∠B = 180°.
While the Angle Addition Postulate states that m∠A + m∠B = m∠C.
Because the context used is that m∠AKG + m∠GKB = 180° and m∠GKB + m∠HKB = 180°, it would be using the Definition of Supplementary Angles.
So Becky is the one who is incorrect.
Answer:
i would say B a stick shift
Step-by-step explanation:
There are two ways you could go about solving this.
You could divide the length of the base (6mm) by 2 and use that to find the area or you could find the area of the whole triangle using 6mm and divide that by 2.
I will use the first method I described:
base = 6/2
base = 3 mm
height = 5.2 mm
area = bh/2
area = (3 * 5.2)/2
area = 7.8 square mm
(don't forget your units)
Using the other method would look like this:
area = bh/2
b = 6
h = 5.2
area = (6 * 5.2)/2
area = 15.6 square mm
area/2 = 7.8 square mm
As you can see either method yields the same result.
Hope this helped.
Cheers and good luck,
Brian
Answer:
a) 4.16 years
b) 27.73 years
c) 238.44 years
d) 3,870.53 years
Step-by-step explanation:
Let X be the random variable that measures the decomposition time.
a)
In this case, since the decomposition time is exponentially distributed with a mean of 1/6, we have
and we must find a t such that P(x>t)=0.5.
b)
c)
d)
