Mathematics
1 answer:
TiliK225 [7]3 years ago
5 0

Answer:

100

Step-by-step explanation:

\frac{x}{5} = 20

isolate the variable, by multiplying both sides by 5

(5) \frac{x}{5} = 20(5)

the 5 cancels out on the right, leaving:

x = 100

How can you tell whether or not a question is a statistical question?
Ray Of Light [21]

A statistical question is one for which you don't expect to get a single answer. Instead, you expect to get a variety of different answers, and you are interested in the distribution and tendency of those answers. For example, "How tall are you?" is not a statistical question. But "How tall are the students in your school?" is a statistical question.

A 100-gram sample of a radioactive isotope decays at a rate of 6% every week. How much of the sample will be left one year from
Dvinal [7]

4 grams sample will be left after 1 year

Step-by-step explanation:

The decay function for percentage decay is given by:

y =a (1-r)^x

Here,

a is the initial value

r is the rate

x is the number of time periods

Given

Initial value = 100 grams

Rate = 6% = 0.06

Time = 1 year = 52 weeks

Putting the values in the formula

y = 100 (1-0.06)^{52}\\y = 100(0.94)^{52}\\y = 4.00\ grams

Hence,

4 grams sample will be left after 1 year

Keywords: Decay, percentage
