If Jillian must average at last 90 on two quiz scores before she can move on the next skill level. Jillian got a 92 on her first quiz. What scores could jillian get on her second quiz in order to move to the next skill level
(92+x)/2 = 90
Solve for x.
To determine what scores Jillian could get on her second quiz to move to the next skill level, we need to find the range of possible scores that would give her an average of at least 90.
Let's assume the score Jillian gets on her second quiz is "x."
According to the given condition, the average of her two quiz scores must be at least 90. Therefore, the equation would be:
(92 + x) / 2 ≥ 90
Now, we can solve this inequality to find the range of possible scores for Jillian on her second quiz:
92 + x ≥ 180
x ≥ 180 - 92
x ≥ 88
Therefore, Jillian must get a score of 88 or higher on her second quiz in order to move to the next skill level.
