Answer:

Find the difference between two integers by adding the additive inverse. The distance is the absolute value of the difference. Check the distance by plotting the original two integers on a number line and counting the units between them.

Step-by-step explanation: Its the right answer

Alex Ar [27]

Answer:

n=\frac{0.5(1-0.5)}{(\frac{0.03}{1.96})^2}=1067.11  

And rounded up we have that n=1068

Step-by-step explanation:

For this case we have the following info given:

ME=0.03 the margin of error desired

Conf= 0.95 the level of confidence given

The margin of error for the proportion interval is given by this formula:  

ME=z_{\alpha/2}\sqrt{\frac{\hat p (1-\hat p)}{n}}    (a)  

the critical value for 95% of confidence is z=1.96

We can use as estimator for the population of interest \hat p=0.5. And on this case we have that ME =\pm 0.03 and we are interested in order to find the value of n, if we solve n from equation (a) we got:  

n=\frac{\hat p (1-\hat p)}{(\frac{ME}{z})^2}   (b)  

And replacing into equation (b) the values from part a we got:

n=\frac{0.5(1-0.5)}{(\frac{0.03}{1.96})^2}=1067.11  

And rounded up we have that n=1068

alexira [117]

You can obtain information about the mean population by taking a random sample of it and taking the average of that sample. The Law of big Numbers says that the bigger the sample, the more likely we will be closer to the real mean value. In other words, the margin of error is less likely to be big.

Katerina is a botanist studying the production of pears by two types of pear trees. she noticed that Type A trees produced 20 pe
Ronch [10]

Answer:

120 pears

Step-by-step explanation:

Let the  number of pears produced by Type B be x

Number of pears  produced by type A=144

  According to question

Type A produce 20% more pears than B

x+ x ×20%= 144

x+x×\frac{20}{100}= 144

\frac{100x+20x}{100}= 144

\frac{120x}{100}=144

x= 144×\frac{100}{120}

x=120 pears

Hence, Number of pears produced by B= 120 pears

Hence, the correct answer is 120 pears
