1/2
When you put a square root into exponential form, the square root turns into an exponential fraction. Since the square root is 2, our fraction would be 1/2

If our root was a cube root, our exponent would be 1/3, etc.

A glacier advances toward the sea 0.004 mile anually. In 2010 the front of the glacier is 6.9 miles from the mouth of the sea. H

olchik [2.2K]

You know where the glacier is now, and how far it moves in
one year. The question is asking how close to the sea it will be
after many years.

Step-1 ... you have to find out how many years

Step-2 ... you have to figure out how far it moves in that many years

Step-3 ... you have to figure out where it is after it moves that far

The first time I worked this problem, I left out the most important
step ... READ the problem carefully and make SURE you know
the real question. The first time I worked the problem, I thought
I was done after Step-2.

============================

Step-1: How many years is it from 2010 to 2030 ?

   (2030 - 2010) = 20 years .

Step-2: How far will the glacier move in 20 years ?

   It moves 0.004 mile in 1 year.

    In 20 years, it moves 0.004 mile 20 times

    0.004 x 20 = 0.08 mile

Step-3: How far will it be from the sea after all those years ?

In 2010, when we started watching it, it was 6.9 miles
      from the sea.

      The glacier moves toward the sea.
   In 20 years, it will be 0.08 mile closer to the sea.
   How close will it be ?

       6.9 miles - 0.08 mile = 6.82 miles (if it doesn't melt)

In order to estimate the mean amount of time computer users spend on the internet each month. How many computer users must be su

evablogger [386]

Answer:

Step-by-step explanation:

Given that confidence level is 95% and sample mean is within 10 minutes of the population mean. i.e. margin of error = 10

Std deviation of population= 211 minutes

Margin of error = Z critical * std error

Std error = sigma/sq rt n = $\frac{211}{\sqrt{n} }$

Hence we have

\frac{211}{\sqrt{n} } $\frac{211}{\sqrt{n} }*1.9641.356\\n>1710$

The minimum sample size is 1710

a) There may not be 1,809 computer users to survey

A small business owner has created a linear regression model to predict the number of new customers who will visit a shop based

coldgirl [10]

Answer: Explanatory variable = " number of times the owner has an advertisement played on the radio"

Response variable = "number of new customers who will visit a shop"

Step-by-step explanation:

An explanatory variable is a kind of independent variable that can be manipulated by researcher in a study to check the response of the response variable.

In the given situation , the business owner is predicting the number of new customers who will visit a shop based on the number of times the owner has an advertisement played on the radio.

Here , He is controlling the advertisement played on the radio to see the response of customers.

Therefore ,

Explanatory variable = " number of times the owner has an advertisement played on the radio"

Response variable = "number of new customers who will visit a shop"
