Anna35 [415]

Answer:

x = 2

Step-by-step explanation:

Five to the power of quantity nine minus three x equals one hundred and twenty five.

----------------------

  • 5^(9 - 3x) = 125
  • 5^(9 - 3x) = 5^3
  • 9 - 3x = 3
  • 3x = 9 - 3
  • 3x = 6
  • x = 6/3
  • x = 2

A dartboard has 20 equally divided wedges and you are awarded the number of points in the section of your dark lands in if you a
Leto [7]

Answer:

Pr =0.75

Step-by-step explanation:

Given

See attachment for wedge

Required

P(x > 5)

The sample space of the wedge is:

S = \{1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20\}

n(S) = 20

The outcomes greater than 5 are:

x > 5 = \{6,7,8,9,10,11,12,13,14,15,16,17,18,19,20\}

n(x>5) =15

So, the probability is:

Pr =\frac{(n(x>5)}{n(S)}

This gives:

Pr =\frac{15}{20}

Pr =0.75
