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

A student measured the lead content of a paint sample 4 times. The standard deviation of the measurements was found to be 0.76%
Lady_Fox [76]

Answer:

CI =0.894%

Step-by-step explanation:

From the question we are told that:

Sample size n=4

Standard deviation \sigma=0.76\% of \=x

Confidence level \mu =90\%=0.90

Degree of Freedom Df=n-1=3

Therefore

Test T from table is given

 t=2.353

Generally the equation for Confidence interval CI is mathematically given by

 CI =t*\frac{\sigma}{\sqrt{n}}

 CI =2.353*\frac{0.76}{\sqrt{4}}

 CI =0.894%

The multiplication law is potentially helpful when we are interested in computing the probability of a. mutually exclusive event
Korvikt [17]

Answer:

b )  the intersection of two events

Step-by-step explanation:

Gary and Steve are both hosting . There are 50 buttons total, 15 buttons are blue and 27 buttons are red. Gary puts all of the buttons into a bag. Steve and Gary both want to wear red buttons.What is the probability ? To solve this problem, you need to understand the Multiplication Rule of Probability.This probability  means to find the probability of the intersection of two events, multiply the two probabilities.

Probability of two events occurring that is called intersection of two events. There are two different set of events , called independent and dependent events.

Independent events  event is not affected by a previous event.

A dependent event is when one event influences the outcome of another event . To find the intersection of two events, whether they are independent or dependent, multiply the two probabilities together.
