The fraction of the original mass that was lost in the second month is 1/12.
<h3>What is the fraction?</h3>
A fraction is a non-integer that is made up of numerators and denominators. An example of a fraction is 1/10.
Weight lost in the first month = 1/6 x 120 = 20kg
Weight lost in the second month = 1/10 x (120 - 20)
= 1/10 x 100 = 10kg
Fraction of the original mass that was lost in the second month : weight lost in the second month / total mass
10 kg / 120 = 1/12

Answer:
We cannot infer at the 10% significance level that the assumption of ski centers is wrong
Step-by-step explanation:
The null hypothesis for this question can be stated as
Null hypothesis H0: =4
Alternate hypothesis Ha:
The test is two tailed
Standard Deviation –
= 2
z=(4.84-4)/(2/sqrt(63))
=3.33
Z(0.1/2)=1.645 is less than Z =3.334
Hence, we will reject H0
Hence, the average growth skier ski’s four times a year is not true
Answer:
D. (x + 7, y - 2)
Step-by-step explanation:
To get back the original after translating left 7 and up 2, you must translate right 7 and down 2. The transformation of choice D does that.
Answer:
These two lines that are running horizontally are parallel lines.
The angle with measure 115 degrees is congruent to angle 2 (by the law of parallel lines).
So, if these two angles are congruent, angle 2 is also 115 degrees.
Let me know if this helps!
