Answer:
9
Step-by-step explanation:
When plugging 6 in for y, you get
2x + 3(6) = 36
You have to multiply 3 and 6, getting
2x + 18 = 36.
Now, you subtract 18 from both sides to isolate the x variable, getting
2x = 18
Now, you divide 2 from both sides because we want x standing by itself, getting
x = 9
Therefore, your answer is 9.
Hope this helped

Conner played a total of 6 +3 + 6 = 15 games. He won or tied 6+ 3 = 9 games.
His percentage is 9/15 = 0.6 x 100 = 60%
April played 5+7+4 = 16 games and won or tied 5 +7 = 12 games.
Her percentage is: 12/16 = 0.75 x 100 = 75%
Tony played 20 games and won or tied 14.
His percentage is: 14/20 = 0.7 x 100 = 70%
April has the highest percentage so she is the one who should play.
Margin of error formula:
ME = z * (Sigma) / √ n
z = 1.96 for a 95 % confidence interval;
Sigma = 3 ( the population standard deviation )
n = 500
ME = 1.96 * 3 / √500 =
= 1.96 * 3 / 22.36 =
= 5.88 / 22.36 = 0.263
Answer:
The margin error for a 95% confidence interval is 0.263.
Answer:
0≤x≤8
Step-by-step explanation:
the domain is basically all the x-values that are applicable to the graph.
Here we can clearly see that the graph starts at x = 0 and ends at x = 8. There are no other possible x-values which is applicable to the graph,
hence the domain is 0≤x≤8
The time needed at 2 meters per second for both rounds would be 100/2 s or 50 seconds. For the first lane he already used 50/1.5 -> 33.33 seconds, so he would need to cover the other 50 meters in exactly 16.67. 50m divided by the 16.67 seconds he has left means he has to swim at a speed of 3 meters per second.
