Answer:

3/4

Step-by-step explanation:

To find the probability of landing on green, we have to divide the number of sections that are green by the total number of sections

we have this as:

6/8 = 3/4

Answer:

$\bar X = \frac{52384 +54079 +52762 +54364 +52584+53987 +53108 +51588 +50554 +53987}{10}=52939.7$

$Mode= 53987$

$Median = \frac{52762+53108}{2}=52935$

$Midrange=\frac{50554+54364}{2}=52459$

Step-by-step explanation:

We can calculate the mean with the following formula:

$\bar X = \frac{\sum_{i=1}^n X_i}{n}$

And if we replace the values given we got:

$\bar X = \frac{52384 +54079 +52762 +54364 +52584+53987 +53108 +51588 +50554 +53987}{10}=52939.7$

The mode is the most repeated value and for this case with a frequency of 2 the mode is:

$Mode= 53987$

In order to find the median we need to order the dataset on increasing way like this:

50554, 51588, 52384 ,52584, 52762

53108, 53987 , 53987 , 54079, 54364

Since we have 10 values an even number the median is calculated from the average between positions 5 and 6 on the data ordered, and we got:

$Median = \frac{52762+53108}{2}=52935$

The mid range is defined like this:

$Midrange = \frac{Max +Min}{2}$

And if we replace we got:

$Midrange=\frac{50554+54364}{2}=52459$

So you do length times width and in your case it would be 14 times 14 = 196

Find x. Leave answers in simplified radical form. (Step by step)

just olya [345]

Answer:

$\sf x = 4\sqrt{2}$

Given:

adjacent: 4 cm
hypotenuse: x cm
angle: 45°

<u>using cosine rule:</u>

$\sf cos(x) = \dfrac{adjacent}{hypotenuse}$

$\sf cos(45) = \dfrac{4}{x}$

$\sf x = \dfrac{4}{cos(45)}$

$\sf x = 4\sqrt{2}$
