Answer:

12 x 3 = 36

Step-by-step explanation:

This is a Multiplication problem Because the Factory can produce 12 shoelaces in 3 minutes so take 12 and multiply it by 3 and your answer is 36. So the factory made 36 shoelaces in that time.

Karen is starting a career as a professional wildlife photographer and plans to photograph Canadian Geese at one of the staging

balandron [24]

Answer:

$5000*0.816 = $4082

Step-by-step explanation:

It's a strange question, but based on the statement and the question it sounds like it's a poisson distribution:

* For 3 days she was able to get 2 good shots (<em>typical of that time of the year</em>)

* Good shots happen randomly

* Each day is independent of another

Let's call 'p' the probability that she makes a good shot per day

Let's call 'n' the number of days Karen is taking shots.

So, if in 3 days he got 2 good shots and that is typical at that time of the year, then the expected value for the number of good shots (X) is:

$E(x)=\frac{2}{3}$

For a Poisson distribution $E (x)=\lambda\\\lambda= np$

So:

$\lambda =\frac{2}{3}$

For a Poisson distribution the standard deviation is:

$\sigma = \sqrt{\lambda}\\\sigma = \sqrt{\frac{2}{3}}$

$\sigma = 0.816$ this is the standard deviation for the number of buentas taken.

So the standard deviation for income is the price of each shot per sigma

$5000*0.816 = $4082, which is the desired response.

How many equilateral triangles in the plane have two vertices in the set {(0, 0), (0, 1), (1, 0), (1, 1)}?

Vadim26 [7]

Answer:

Step-by-step explanation:

There are 4 points, so there are C(4,2) = 4C2 = 6 pairs of

points and since two equilateral triangles can be drawn having

that pair of points as vertices, there are 12 equilateral

triangles that can be drawn having two vertices in the set

{(0,0), (0,1), (1,0), (1,1)}.

Kathleen worked for 4 hours and 45 minutes. How should she write that on her time card?

Yuri [45]

Answer:

4.75 hours.

Step-by-step explanation:

We have been given that Kathleen worked for 4 hours and 45 minutes.

We will convert 45 minutes to hours by dividing 45 by 60 as one hour has 60 minutes.

$\frac{\text{45 minutes}}{\frac{60\text{ minutes}}{\text{hour}}}$

$\frac{\text{45 minutes}}{60}\times \frac{\text{ hour}}{\text {minutes}}$

$\frac{3}{4}\times \text{ hour}$

$0.75\text{ hour}$

Therefore, she should write 4.75 hours on her time card.
