Answer:
x = 9
Step-by-step explanation:
Both the triangles are similar, so the corresponding sides are also similar.
That is,
12 / 8 = x / 6
Cross multiply,
x * 8 = 12 * 6
8x = 72
Divide 8 on both sides,
x = 72 / 8
x = 9
Answer:
76.2838
Step-by-step explanation:
E[X+Y] = E[X] + E[Y]
E[X] is the average of X or expectancy of X
E[Y] is the average or expectancy f Y
E[X] = 40P(student is in bus 1)+33P(student is in bus 2)+25P(student is in bus 3)+50P(student is in bus 4)=
40(40/148) + 33(33/148) + 25(25/148) + 50(50/148) = 39.2838
E[Y] = (number of students)/(number of drivers) = 148/4 = 37
So E[X+Y] = 39.2838 + 37 = 76.2838

The size of the paper is 5 inch by 7 inch
Hence, considering the longest side of paper representing the length of the car, it can be said that the drawing will fit the index card.
