Answer:

Approximately 104 joggers are female

Step-by-step explanation:

The U.S census bureau reported that 9 out of every 20 joggers at female.

Let x be the number of females out of 230 joggers.

Rewrite it as

$\begin{array}{cc}\text{Female}&\text{All joggers}\\9&20\\x&230\end{array}$

Now we can write a proportion:

$\dfrac{9}{x}=\dfrac{20}{230}$

Cross multiply:

$20x=9\cdot 230\\ \\2x=9\cdot 23\ [\text{Divided by 10}]\\ \\x=\dfrac{9\cdot 23}{2}=\dfrac{207}{2}=103.5\approx 104$

Answer:

Step-by-step explanation:

TO find the value for the terms, substitute n for the number in the sequence. so

for 1st term n = 1

for 2nd term n =2 etc.

1st Term = 1^2-3 = 1-3 = -2

2nd term = 2^2 - 3 = 4-3 = 1

3rd Term = 3^2 - 3 = 6

10th Term = 10^2 - 3 = 100 - 3 = 97
