Does crime pay? The FBI Standard Survey of Crimes showed that for about 80% of all property crimes (burglary, larceny, car theft

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

⇒ $n>=10.31$

$n=11 \ crimes$

One number exceeds another by 26. the sum of the numbers is 58. what are the numbers

Gnom [1K]

First number = X

second number = x +26 ( exceeds means higher so add 26)

x + x+26 = 58

combine like terms:

2x + 26 = 58
subtract 26 from each side:

2x = 58-26

2x = 32

divide both sides by 2:
x = 32/2
x = 16

first number is 16
second number = 16+26 = 42
