Evaluate [(40 + 5) - 3^2] divided by 9 times 2

Estimate √97.5 / 1.96

evablogger [386]

Answer: 5

Step-by-step explanation:

1. You have the following expression given in the problem above:

$\frac{\sqrt{97.5}}{1.96}$

2. You can estimate the result by rounding the numerator and the denominator.

3. As you can see, you can round up 97.5 to 100.

4. Then, you can round up 1.96 to 2.

5. Therefore, you have:

$\frac{\sqrt{100}}{2}$

$\frac{10}{2}=5$

6. Therefore, the result is 5.

7th term in geometric sequence an=2 5(n-1)

Soloha48 [4]

To find the 7th term, all you have to do is plug it in the equation.

First n would equal 7 because we are looking for the 7th term.

Now, let's plug everything we know into the equation.

a7 = 2+5 * (7-1)

= 2 + 5 * 6

= 2 + 30

= 32

In conclusion, the 7th term would equal 32.

Use the graphing tool to create a histogram of Gretchen’s data. Use eight bins for your histogram.

lozanna [386]

The number of bins in the histogram determines the width of the bins and

the frequency (number of members) in a bin.

Please find attached the graph of the histogram of Gretchen's data created with MS Excel.

<h3 /><h3>Method used to create the histogram of Gretchen's data</h3>

Given:

The table from Gretchen's data is presented as follows;

$\begin{tabular}{|c|c|} \underline{ Member}& \underline{Number of Days}\\x_1&2\\x_2&4\\x_3&7\\x_4&8\\x_5&12\\x_6&15\\x_7&10\\x_8&7\\x_9&9\\x_{10}&6\\x_{11}&13\\x_{12}&3\\x_{13}&8\\x_{14}&10\\x_{15}&10\end{array}\right]$

The required number of bins = 8 bins

The steps to create the histogram using MS Excel;

Enter the 15 dataset for the number of days as presented in the above table in a column on the worksheet.

Select the dataset entered into the cells from above then select the Insert menu.

In the Chart section of the insert menu click on the Histogram icon to view the quick options for histograms type charts.

Select the Histogram option from the drop down menu from the quick options for histograms, to create an histogram chart.
