I just need help finding h pleasww
SCORPION-xisa [38]

Answer:

  • h = (2/3)√3
  • b = 3√2

Step-by-step explanation:

It is useful to remember the ratios between the side lengths of these special triangles.

  30°-60°-90° ⇒ 1 : √3 : 2

  45°-45°-90° ⇒ 1 : 1 : √2

__

h is the shortest side, and the given length is the intermediate side. This means ...

  h/1 = 2/√3

  h = 2/√3 = (2/3)√3 . . . . . . simplify, rationalize the denominator

__

b is the longest side, and the given length is the short side. This means ...

  b/√2 = 3/1

  b = 3√2 . . . . . multiply by √2

emma will roll two number cubes labeled 1 through 6. She will record the sum of the two numbers after each roll. She will roll t
SashulF [63]

Answer:

75 times

Step-by-step explanation:

First of all let's ook at the 36 possible outcomes and their sums.

2=1,1

3=1,2 2,1

4=1,3 ; 2,2 ; 3,1

5=1,4 ; 2,3 ; 3,2 ; 4,1

6=1,5 ; 2,4 ; 3,3 ; 4,2 ; 5,1

7=1,6 ; 2,5 ; 3,4 ; 4,3 ; 5,2 ; 6,1

8=2,6 ; 3,5 ; 4,4 ; 5,3 ; 6,2

9=3,6 ; 4,5 ; 5,4 ; 6,3

10=4,6 ; 5,5 ; 6,4

11=5,6 ; 6,5

12=6,6

Looking at the above, there are 4 sums equal to 5 out of a total of 36 sums.

Thus, probability of getting a sum equal to 5 is;

P(5) = 5/36

Now,since the cubes are rolled 540 times, number of times a sum equal to 5 will appear will be;

(5/36) x 540 = 75 times
