Answer:
y = -x -
Step-by-step explanation:
Slope intercept form: y = mx + b
To put the equation in slope intercept form, isolate the y:
2x + 3y = -7
3y = -2x - 7
y = -x -
<u>Answer-</u>
<em>In </em><em>25.15%</em><em> cases their response times is over 30 minutes.</em>
<u>Solution-</u>
Hint- Calculating the z-score (how much standard deviations away from the mean) and then getting the corresponding probability value from normal distribution table we can get solution.
Applying the formula for Z-score,
Here,
X = score = 30,
μ = mean = 22,
σ = standard deviation = 11.9
Putting the values,
(Subtracted from 1 as the values of area to the left of the Z score is given in table, but we need the area right to Z score as response times more than 30 minutes is asked)
