Find the mean of the first 7 odd prime number?

bekas [8.4K]

Answer: 75/7 or 10.71 (rounded)

Step-by-step explanation:

Mean = Average

To find the average you should add all the numbers together and then divide it by the amount of numbers.

In this question, the formula is $\frac{n_1+n_2+n_3+n_4+n_5+n_6+n_7}{7}$

----------------------------------------------------------------------------------------

The list of the first 7 odd prime numbers:

3, 5, 7, 11, 13, 17, 19

Now, add them together

3+5+7+11+13+17+19=75

Divide the sum by 7

75÷7=75/7=10.71 (rounded)

Hope this helps!! :)

Find the slope and y-intercept of 3y - 4x = 39

Alexus [3.1K]

<h2>Greetings!</h2><h3>Firstly, the slope is found by rearranging the formula:</h3>

3y = 4x + 39

y = $\frac{4x}{3}$ + $\frac{39}{3}$

When x is 0, y = 0(x) + $\frac{39}{3}$ , so the y intercept is $\frac{39}{3}$

<h3>Next, the slope is simply the number in front of the x, </h3>

So $\frac{4x}{3}$ can be rearranged to $\frac{4}{3}x$ , so the slope would be $\frac{4}{3}$ .

<h2>Hope this helps!</h2>
