Answer:

36/121

Step-by-step explanation:

Probability is a relation between the amount of appropriate results and the total amount of results.

The total amount of the marbles is 6+5=11

We must take only blue marbles so the amount of appropriate results is 6.

The probability of taking blue marble in the 1st turn is 6/11. Then we put the marble back so the amount of marbles doesn't change. That's why the probability of taking blue marble in the 2nd turn is also 6/11.

But we have to count the probability of taking blue marble in both cases. To do it we must multiply the probability of taking blue marble in the 1st turn and the probability of taking blue marble in the 2nd turn.

(6/11)*(6/11)=36/121

What is the area, in square inches, of the isosceles trapezoid below?
Nostrana [21]

Area of a trapezoid: (top + bottom)/2 x height

Area = (6.5 + 15.1)/2 x 5

Area = 21.6/2 x 5

Area = 10.8 x 5

Area = 54 square inches.

A building 50 ft high casts a 75-ft shadow. Sarah casts a 6-ft shadow. The triangle formed by the building and its shadow is sim
Rom4ik [11]
Make each known side into a ratio like so...
75/6 
(Because 75 is the shadow casted by the building, and 6 is the shadow casted by sarah)
and 50/x 
(50 is how tall the building is and sarah's height is what needs to be found) 
Therefore, 
75    50
----  -----
 6      x

Do cross products;
50 x 6 = 75 x X
300 = 75x 
Divide by 75 
x = 4ft

An athletic director pays $90 for 12 sun visors for the softball team. how much will the athletic director pay to buy 15 more su
satela [25.4K]

An athletic director pays $90 for 12 sun visors for the softball team. The rate per sun visor is equal to $90 / 12 sun visor = $ 7.5 per sun visor. So the athletic director should pay ($ 7.5 per sun visor)*(15 sun visor) = $ 112.5

If [x] denotes the least integer greater than or equal to x and [x/2] = 0, which of the following could be the value of x?A. -2B
podryga [215]

Answer:

B) -3/2

Step-by-step explanation:

If [x/2]=0 then x/2 is a number such that the least integer greater than or equal to x/2 is 0. We can rewrite this as the inequality x/2≤0. Then, the value of x in C, D and E is wrong because they are positive numbers, then x/2 would be a positive number which contradicts this inequality.

Now, 0 is the least integer that satisfies this inequality, therefore we cannot have that x/2≤-1 since -1 is an integer and -1<0. Then x/2>-1. This discards A as wrong, because for x=-2, x/2=-1, contrary to x/2>-1.

Thus B is the right answer. To verify, if x=-3/2, then x/2=-3/4 and we have that -1<-3/4≤0 as required.
