Probability the two numbers will have a sum of 5: P
P=(Number of favorable results)/(Number of possibe results)

Number of favorable results: 4
1) Dice 1: 1 and Dice 2: 4
2) Dice 1: 2 and Dice 2: 3
3) Dice 1: 3 and Dice 2: 2
4) Dice 1: 4 and Dice 2: 1  

Number of possible results: 36

P=4/36
Simplifying, dividing the numerator and the denominator by 4:
P=(4/4)/(36/4)
P=1/9

Answer: Option B. 1/9

Answer:

it's 1/7^2

Step-by-step explanation:

When multiply bases with exponents, as long as they are the like bases, you add the exponents. 7^3 x 7^-5 = 7^-2.

When you have a negative exponent, you can get rid of it by moving it to a fraction. put a 1 over the base and exponent and drop the negative, so 1/7^2

Please I need help!!!
inessss [21]

Answer:

  44 ft

Step-by-step explanation:

There are a couple of ways this can be worked. You could find the height of the tower, then use the Pythagorean theorem to find the wire length.

Or, you can find the wire length for the smaller triangle and scale up the result to the larger triangle. We choose this method.

The length of the wire (w) from the stake to the top of the pole is given by the Pythagorean theorem:

  w² = 4² +7² = 16 +49 = 65

  w = √65 . . . . . . take the square root

The base of the larger triangle is 18+4 = 22. The scale factor from the smaller to larger triangle is the ratio of base lengths: 22/4 = 11/2

The overall length of the guy wire is this ratio times "w" ...

  (11/2)√65 ≈ 44 . . . . feet
