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!! :)

HELPPP QUICKKK PLSSSS PEOPLE I NEED HELP NOW PLSSSSS Which of the following equations describes the line shown below? Check all
Sav [38]

Let there exists a point (x, y) on the given line.

Slope of all points must be same, as they lie on the same line.

=> (y - 1)/(x - 2) = (4 - 1)/(-4 - 2)

=> (y - 1)/(x - 2) = - 1/2

=> y - 1 = (-½) (x - 2)

Option 1 is the correct option

trasher [3.6K]

\bf \begin{array}{ccll} \stackrel{paint}{gallons}&fence\\ \cline{1-2} \\\frac{1}{4}&\frac{2}{3}\\\\ x&1 \end{array}\implies \cfrac{~~\frac{1}{4}~~}{x}=\cfrac{~~\frac{2}{3}~~}{1}\implies \cfrac{~~\frac{1}{4}~~}{\frac{x}{1}}=\cfrac{2}{3}\implies \cfrac{1}{4}\cdot \cfrac{1}{x}=\cfrac{2}{3} \\\\\\ \cfrac{1}{4x}=\cfrac{2}{3}\implies 3=8x\implies \cfrac{3}{8}=x
