dedylja [7]

Answer:

The appropriate answer is "11 crimes".

Step-by-step explanation:

Let,

The number of crimes be "n".

Now,

⇒ P(solved \ at \ least \ one) = 1-P(solved \ none \ of \ n)

or,

⇒ 1-(0.8)^n>0.9

⇒       (0.8)^n

By taking log both sides, we get

⇒ n>=\frac{log(0.1)}{log(0.8)}

By putting the values, we get

⇒ n>=10.31

      n=11 \ crimes

Find volume of this prism
attashe74 [19]

Answer:

324 km²

Step-by-step explanation:

The prism shown is a square pyramid

The volume of a square pyramid can be calculated by using this formula

V=lw\frac{h}{3}

where l = length of base, w = width of base and h = height

We are given the following dimensions...

length of base = 9 km

width of base = 9 km

height = 12 km

To find the volume of the pyramid, we plug in these given values into the formula

Hence,

V = 9 * 9* \frac{12}{3} \\\frac{12}{3} =4\\V = 9*9*4\\9*9=81\\81*4=324\\

V = 324
