One year British columbia had 6149 police officers and a total population of 3282000 Nova scotia had 1542 police officers and a total population of 900000 which province had the greater number of people per police officer

Answers

Answer 1

Answer:

Answer: Nova Scotia

Step-by-step explanation:

British Columbia people per police officer:

= Population number / no. Of policemen

= 3,282,000/6,149

= 534 people per policeman

Nova Scotia

= 900,000 / 1,542

= 584 people per policeman

4m + 9 + 5m - 12 = 42

Answers

First, combine like terms.

4m+5m = 9m

9m + 9 - 12 = 42

9-12= -3

9m - 3 = 42

Second, apply the inverse operation to isolate the variable.

9m - 3 = 42
+3 +3

9m = 45

Third, divide 9 by both sides to solve for m.

$(9m)/(9) = (45)/(9)$

m = 45/9

m = 5

Answer: $m = 5$

4m+9+5m-12=42 is 5. m= 5.

Suppose 70% of kids who visit a doctor have a fever, and 45% of kids with a fever have sore throats. What's the probability that a kid who goes to the doctor has a fever and a sore throat?I am stuck on this question, sadly I just did a lot of these for my exams but I forget how to solve it. Someone help??

Answers

To find the probability that a kid has both a fever and a sore throat, multiply the two probabilities together: 70% * 45% = 31.5%

70/100 = 0.7%
45/100 = 0.45%
0.7 x 0.45 = 0.31
0.31= 31%
31% is your answer sir

Robert runs 25 miles. His average speed is 7.4 miles per hour. He takes a break after 13.9 miles. How many more hours does he run? Show your work

Answers

Answer: Robert runs for approximately 1.50 more hours after taking a break.

Step-by-step explanation:

To find out how many more hours Robert runs after taking a break, we need to determine the time it takes for him to run the remaining distance.

We know that Robert runs a total of 25 miles and his average speed is 7.4 miles per hour. To find the time it takes for him to run the entire 25 miles, we can use the formula:

Time = Distance / Speed

Time = 25 miles / 7.4 miles per hour

Time ≈ 3.38 hours

Since Robert takes a break after running 13.9 miles, we need to subtract the time it took him to run that distance from the total time.

To find the time it took him to run 13.9 miles, we can use the formula:

Time = Distance / Speed

Time = 13.9 miles / 7.4 miles per hour

Time ≈ 1.88 hours

Now, we can subtract the time for the break from the total time to find how many more hours Robert runs:

Remaining time = Total time - Time for the break

Remaining time ≈ 3.38 hours - 1.88 hours

Remaining time ≈ 1.50 hours

Therefore, Robert runs for approximately 1.50 more hours after taking a break.

Answer:

1.5 hours more

Step-by-step explanation:

In order to find out how many more hours Robert runs, we need to find the total time it takes him to run 25 miles. We can do this by dividing the total distance by his average speed.

$\sf \textsf{Total time }= \frac{\textsf{Total distance }}{\textsf{ Average speed}}$

$\sf \textsf{Total time }=\frac{ 25 miles }{7.4\textsf{ miles per hour}}$

$\sf \textsf{ Total time = 3.378378378378378 hours}$

We already know that Robert takes a break after 13.9 miles. This means that he runs for:

$\sf \textsf{25 miles - 13.9 miles = 11.1 miles after his break}$

And to find out how many hours Robert runs after his break, we need to divide the distance he runs after his break by his average speed.

$\sf \textsf{Time after break } =\frac{\textsf{ Distance after break }}{\textsf{Average speed}}$

$\sf \textsf{Time after break CD call }=\frac{ 11.1 miles }{\textsf{ 7.4 miles per hour}}$

$\sf \textsf{Time after break = 1.5 hours}$

Therefore, Robert runs for 1.5 hours more after his break.

The vertical height v, in feet, of a snowboarder jumping off of an overhang can be modeled by the function h(t)=15-10t-16t^2, where 15 is the initial height (in feet) of the overhang, -10 is the initial vertical velocity (in feet per second), and t is the time (in seconds). How long does it take the snowboarder to land after jumping off the overhang?"

Answers

Step-by-step explanation:

It is given that, the vertical height v, in feet, of a snowboarder jumping off of an overhang can be modeled by the function as :

$h(t)=15-10t-16t^2$

Where

15 is the initial height of the overhang

-10 is the initial vertical velocity

t is in second

We need to find the time taken by the snowboarder to land after jumping off the overhang. At this condition,

h(t) = 0

So, $15-10t-16t^2=0$

On solving above equation using online calculator, we get the value of t = 0.705 seconds. So, the time taken by the snowboarder to land after jumping off the overhang is 0.705 seconds.

I don't know for sure, but I think there might be an error in the way you copied your function. In all of my dealings with these types of problems, I have learned the formula to be h(t) = 15 + 10t - 16t^2. Notice the plus in front of the "10t". This is due to the fact that if he pushes off of the overhang he would have an upward force of 10 feet per second as soon as his feet left the ground. The only thing pulling him back to Earth is gravity, modeled by the "-16t^2". This is derived from a bit of slightly advanced physics involving the gravitational constant, but let's work under my formula for a second...

Either way, we will wind up using the Quadratic Formula (or possibly factoring if the numbers are easy enough to work with). So let's start.

h(t)= 15 +10t - 16t^2

In order to use the QF or factoring I will need to make h(t)=0. Simply done by:

0= 15 +10t -16t^2

Looking at the numbers, I'd prefer to use the QF so here it is:

$x= \frac{-b + or - \sqrt{b^(2)-4ac } }{2a}$

I know that my answer will need to be positive since you can't have a negative value when dealing with time, so I will eliminate the positive sign from the "+or-" part leaving me with:

$x= \frac{-b -\sqrt{b^(2)-4ac } }{2a}$

And I know that a= -16, b= 10, and c=15. So all that's left to do is substitute and solve.

$x= \frac{-10 -\sqrt{-16^(2)-4*-16*15 } }{2*-16}$

There's a decent amount of math that would be difficult and sloppy for me to do over the computer, but all you need to do is solve the rest of the equation and you would get your answer.

Exact answer: $(5-4 √(15) )/(8)$ or rounded answer: ≈1.31 seconds.

Hope this helps!
