ashley is on a road trip. so far she has traveled 28.61% of the trip which is 101 miles. how many miles is the entire trip?

bulgar [2K]

Answer:

Around 300 Miles

Step-by-step explanation:

Nots sure of the exact number. If 28% of the trip is 101 miles then 50% would be around 210 miles.

So the entire trip as a whole should be near 300 miles.

Hope this Helps!

Thirty students in the fifth grade class listed their hair and eye colors in the table below: Brown hair Blonde hair Total Green

Mars2501 [29]

Answer:

No, the events "brown hair" and "brown eyes" are not independent.

Step-by-step explanation:

The table that represents the hair and eye colors of thirty students of the fifth grade are given in table as:

Brown hair Blonde hair Total

Green eyes 9 6 15

Brown eyes 10 5 15

Total 19 11 30

No, the events "brown hair" and "brown eyes" are not independent.

Since, two events A and B are said to be independent if:

P(A∩B)=P(A)×P(B)

where P denotes the probability of an event.

Here we have:

A= students having brown hair.

B= students having brown eyes.

A∩B= students having both brown hair and brown eyes.

Now,

P(A)=19/30 (ratio of addition of first column to the total entries)

P(B)=15/30 ( ratio of addition of second row to the total entries)

Also,

P(A∩B)=10/30

Now as:

P(A∩B) ≠ P(A)×P(B)

Hence, the two events are not independent.

According to u.s. postal regulations, the girth plus the length of a parcel sent by mail may not exceed 108 inches, where by "gi

Pepsi [2]

Let x represent the side length of the square end, and let d represent the dimension that is the sum of length and girth. Then the volume V is given by
V = x²(d -4x)
Volume will be maximized when the derivative of V is zero.
dV/dx = 0 = -12x² +2dx
0 = -2x(6x -d)
This has solutions
x = 0, x = d/6

a) The largest possible volume is
(d/6)²(d -4d/6) = 2(d/6)³
= 2(108 in/6)³ = 11,664 in³

b) The dimensions of the package with largest volume are
d/6 = 18 inches square by
d -4d/6 = d/3 = 36 inches long
