The 2017 population of California was 39536653 and of Arizona was 7016270. Compute and compare the rate of pedestrian fatalities

jasenka [17]

Answer:

The pedestrian fatality rate for California per 100,000 residents would be;

= (858/39,536,653) * 100,000

= 2.17 people per 100,000

In Arizona that figure is;

= (216/7,016,270) * 100,000

= 3.08 people per 100,000

This shows that even though California has a higher number of pedestrian fatalities in absolute terms, when this figure is made relative to population, Arizona has more pedestrian fatalities.

A three-digit number has tens digit two greater than the units digit and the hundreds digit one greater than the tens digit. The

Paha777 [63]

Answer:

875

Step-by-step explanation:

As given, there is a three digit number

So, let assume three digit number be `xyz`.

Now, as given tens digit is 2 greater than the unit digit.

∴ $y= 2+z$

Next, the hundred digit one greater than the tens digit.

∴ $x= 1+y$

The sum of the tens and the hundreds digits is three times the units digit.

∴ $x+y= 3z$

Now, substituting the value in the equation.

$x+y= 3z$

⇒ $(1+y)+y= 3\times (y-2)$

solving it to get value of y

⇒ $2y+1= 3y-6$

⇒ $-y= -7$

∴ $y=7$

Next, finding value of z

y= $2+z$

substituting the value of y and subtracting both side by 2

∴ z= $7-2= 5$

Last, finding the value of x

$x=1+y$

substituting the value of y

∴ x= 8

xyz= 875
