A few that is charged per call.
It’s the constant which means that it isn’t going to change. It can’t be the total cost because there is no equal sign. It can’t be the cost per minute because the x represents the minutes, which means .1 represents the cost. Lastly it cannot be how long the call lasted because m is the minutes which is the length of the call.

Mark McGuire hit 70 home runs in the 1998 season. Given that there are 4 bases & 90 feet between each base, how many miles d
alekssr [168]

Answer:

4.8 or about 5 miles

Step-by-step explanation:

In order to solve this problem, you must first multiply the 4 bases × 90 feet to get how much feet he runs in 1 home run. 4 × 90= 360 feet. Then you must multiply 360 feet × 70 homeruns, this will give you how many feet he ran in 70 homeruns. Your answer will be 25,200 feet. Now, there are 5,280 feet in <em>one</em> mile, so you must divide 25,200 by 5,280. Using a calculator, my answer was 4.7727272727. I then rounded it up to 4.8 miles, or about 5 miles.

The margin of error is a statistic that expresses how much random sampling error there is in a survey's results. The Margin of error in this survey is 1%.

<h3>What is the margin of error?</h3>

The margin of error is a statistic that expresses how much random sampling error there is in a survey's results. The wider the margin of error, the less confident one should be that a poll result reflects the outcome of a population-wide survey.

The random sample of 2500 sports fans, out of which 61% prefer basketball over soccer, therefore, we can write n=2500 and p=0.61. Thus, the margin of error can be written as,

MOE=\sqrt{\dfrac{\hat p(1-\hat p)}{n}} = \sqrt{\dfrac{0.61(1-0.61)}{2500}} = 0.00975 = 0.975\% \approx 1\%

Hence, the Margin of error in this survey is 1%.
