The answer would be 40/10 because there are 4 blocks in each set, there are 10 sets, and all the blocks are positive.

Two dice are rolled. What is the probability that the sum of numbers rolled is either 5 or 12?

Maksim231197 [3]

ANSWER:

The probability that sum of numbers rolled is either 5 or 12 is $\frac{5}{36}$

SOLUTION:

Given, Two dice are rolled.

We have to find what is the probability that the sum of numbers rolled is either 5 or 12

We know that, probability of an event = $\frac{\text { favourable outcomes }}{\text { total outcomes }}$

Now, total outcomes for two dices = 6 for 1st dice x 6 for 2nd dice = 6 x 6 = 36.

Now, favourable outcomes = sum is 5 + sum is 12

= 4[(1,4), (2,3), (3, 2), (4, 1)] + 1[(6,6)]

= 5 total favourable outcomes.

Now, probability = 5/36

Hence, the probability that sum is either 5 or 12 is 5/36.

5y-30=-5y+30 and also can you show the steps :}

KatRina [158]

5y-30=-5y+30

add 30 to both sides

5y = -5y+60

add 5y to both sides

10y = 60

divide both sides by 10

y = 6

hope this helps!

One leg of an isosceles right triangle measures 5 inches. Rounded to the nearest tenth, what is the approximate length of the

Anestetic [448]

By definition, in an isosceles triangle, the two legs will have congruent lengths.

Since we know that one leg measures 5 inches, we know the other must measure 5 inches as well.

The Pythagorean Theorem states that in a right triangle, a² + b² = c².

Knowing that, we can substitute in our known values.

(5)² + (5)² = c²

From there, we can square our values.

(25) + (25) = c²

And from there, we can add the values together.

(50) = c²

Finally, we can find the square root of both values to give us the length of the hypotenuse.

7.07106781187 = c

And since we're rounding to the nearest tenth, we can rewrite this answer as:

7.1 = c

Therefore, the approximate length of the hypotenuse is 7.1 inches.

Hope this helped! :)
