What is the probability of rolling a sum of 8 on at least one of two rolls of a pair of number cubes?

RideAnS [48]

<span>P(At least one sum of 8) = 1 - P(No sums of 8)

P(At least one sum of 8) = 1 - (1 - 5/36)^2

P(At least one sum of 8) = 1 - (31/36)^2

P(At least one sum of 8) = 1 - 961/1296

P(At least one sum of 8) = 335/1296

So the answer is choice B

6 times the sum of a number and 7 is 18

lutik1710 [3]

The simplest way to find this number is to add your two known values (7 and 6) which should be 13. Now you should subtract it from 18. (18-13). That should equal to 5, which is your answer.

Answer:

Hence, (75,40) is the maximum point and maximum profit is $192.5

Step-by-step explanation:

Let the breakfast be x

And let the lunch or afternoon be y

Inequalities will become

$\frac{1}{3}x+\frac{1}{2}y\leq 45$

$\frac{2}{3}x+\frac{1}{2}y\leq 70$

And objective function will be

Z=1.5x+2.0y

You can see the graph in the attachement

ABCD is the feasible region

Points of feasible region is (0,90) ,(0,0) ,(75,40) and(105,0)

We have to find Z by substituting the points of feasible region

At (0,90) we get

Z=1.5(0)+2(90)

Z=180

At (0,0)

Z=1.5(0)+2(0)

Z=0

At (75,40)

Z=1.5(75)+2(40)

Z=192.5

At (105,0)

Z=1.5(105)+2(0)

Z=157.5

The maximum number we are getting is 192.5 which is at (75,40)

Hence, (75,40) is the point of maximum

Answer:

NO, It’s not a right triangle

Explanation:

Using the converse of Pythagoras’ theorem if the triangle is right then

Square on longest side = sum of square of the other sides

70^2= 4900

55^2 + 42^2 = 4789

Since 4900 ≠ 4789 not a right triangle
