Answer:
About 91%
Step-by-step explanation:
According to the box plot provided :
Total number of students = 40
Minimum weight = 152 pounds
Third quartile (Q3) = 245
The approximate percentage of students that weigh 245 kg or less
About 10 of the intervals out of the 11 coverage interval of the box plot fall between 152 and 254 ; Hence,
(10 / 11) * 100
90.90
= about 91 % of the total students weigh 245 kg or less
Answer:
x = 250
y = 125
u(x,y) = 3125500
Step-by-step explanation:
As given,
The utility function u(x, y) = 100xy + x + 2y
= 2 ,
= 4
Now,
Budget constraint -
x +
y = 1000
⇒2x + 4y = 1000
So,
Let v(x, y) = 2x + 4y - 1000
Now,
By Lagrange Multiplier
Δu = Δv
⇒< 100y + 1, 100x + 2 > = < 2, 4 >
By comparing, e get
100y + 1 = 2 ........(1)
100x + 2 = 4 .........(2)
Divide equation (2) to equation (1) , we get

⇒2(100y+1) = 1(100x+2)
⇒200y + 2 = 100x + 2
⇒200y = 100x
⇒2y = x
Now,
As 2x + 4y = 1000
⇒2x + 2(2y) = 1000
⇒2x + 2x = 1000
⇒4x = 1000
⇒x = 250
Now,
As 2y = x
⇒2y = 250
⇒y =
= 125
∴ we get
x = 250
y = 125
Now,
u(250, 125) = 100(250)(125) + 250 + 2(125)
= 3125000 + 250 + 250
= 3125000 + 500
= 3125500
⇒u(250, 125) = 3125500
I'm pretty sure that 20 is 5 but other than that, I can't help with anymore.
700 people were surveyed.
SOLUTION
70/10%
=700
Or
7 x 10^2
=700
HOPE THIS HELPS!! :))
