Step-by-step explanation:
Since we have given that
Time taken by steamboat makes the trip=5 hours
Time taken by yacht makes the trip =2.5 hours
Since we have also given that
the yacht is 20 knots faster than the steamboat,
So let the speed of steamboat be x
Let the speed of yacht be x+20
Now, we have given that both boats will travel the same distance ,
So,

Hence,

Step-by-step explanation:
From given data,
n = 1496
x = 478
Proportion estimate ( p ) = 
=
= 0.3195 ≅ 0.31
Proportion estimate ( p ) = 0.31
∴ The proportion of new car buyers who prefer foreign cars -> 0.31
Answer:
136 cubic feet
Step-by-step explanation:
2x2x2= 8
4x4x8 = 128
128 + 8 = 136
Answer:
Step-by-step explanation:
Perimeter of a rectangle = 2(l+b)
Let the length be x
then width = x-2
44 ft = 2(l+b)
44ft = 2(x + x-2)
44ft = 2(2x-2)
44 ft = 4x -4
44+4 = 4x
48 = 4x
x = 48/4 = 12
Length = <u>x = 12</u>
Width = <u>x-2 = 12-2 =10</u>
<u></u>
<u>Length is 12 and width is 10</u>
<u></u>
<u>check if its correct </u>
2(l+b) = 44
2(12+10)=44
2(22) = 44
