They meet their median goal because if you rearrange the numbers from lowest to highest, the median mileage of their line of cars would be 19,23,25,26,29. There are five numbers of car mileages therefore 25 would serve as the median for all five mileages.
Answer:
a) E(X) = 3.30
b) If these are the only two grades (A and B) available in the school, then this calculated expected value will truly be the expected GPA for each quarter or semester But, if like real life, there are other grades available at the school not included in this calculation, then this value seizes to be the expected value for the GPA over any time period.
Step-by-step explanation:
P(X=xᵢ) = pᵢ
For an A,
P(X=4.0) = 0.3
For a B
P(X=3.0) = 0.7
But E(X) = Σ xᵢpᵢ
E(X) = (0.3 × 4.0) + (0.7 × 3.0) = 3.30
b) If these are the only two grades available in the school, then this calculated expected value will truly be the expected GPA for each quarter or semester But, if like real life, there are other grades available at the school not included in this calculation, then this value seizes to be the expected value for the GPA over any time period.
Answer:
Step-by-step explanation:
Answer:
Step-by-step explanation:
Y=3x-4
Slope of this line = 3
Slope of the line parallel to this line = 3 {slope of parallel lines are equal}
Slope of the line perpendicular to this line = -1/3 {product of the slope of perpendicular lines= -1}
