Can someone help me on question 8

Mathematics
1 answer:

Answer:

x = -7, y = 3

Step-by-step explanation:

x = -2y - 1

x = 3y - 16

so:

-2y - 1 = 3y - 16

add 2 y to each side of the equation:

-1 = 5y - 16

add 16 to each side:

5y = 15

divide both sides by 5:

y = 3

x = 3(3) - 16 = -7

Answer:

\bullet \ \large\text{The mean in period 2 is higher than the mean in period 1.}

Step-by-step explanation:

<u><em>the mean in period</em></u> 1 :

(2.3+2.1+2.2+2.2+2.2+2.1+2.4+2.5+2.2+2.0+1.9+1.9+2.1+2.2+2.3)÷15=21.733...

<u><em>the mean in period</em></u> 2 :

(2.3+2.1+3.3+1.5+3.6+1.6+3.0+1.1+4.7+2.1+2.4+1.9+2.8+0.5+2.3)÷15=23.466...

Since 23.466 > 21.733 then “The mean in period 2 is higher than the mean in period 1”.

So, we have the following equation...

3^2*3^3=(?)

Remember 3^2 and 3^3 is the following...

3^2=3*3\\3^3=3*3*3

Therefore, 3*3=9\\3*3*3=27\\9*27=243

So, your final answer is \boxed{243}.
