Find the midpoint of the line segment with the given endpoints
mezya [45]

Answer:

Option D.

Step-by-step explanation:

Hey there!

The given points are:(-4,-10) and (2,1).

Now; use midpoint formula,

(x,y) =  (\frac{x1 + x2}{2} , \frac{y1 + y2}{2} )

Put all values.

(x,y) =  (\frac{ -4  + 2}{2} , \frac{ - 10 + 1}{2} )

Simplify it.

(x,y) = ( - 1, \frac{ - 9}{2} )

(x,y) =  (- 1,- 4 \frac{1}{2})

Therefore, your required answer is Option D.

Svetach [21]

Answer:

a) P=0.2

b) P=0.1

Step-by-step explanation:

We have a total of 1,000 employees in the company.

Out of this 1,000 employees, 200 had colds. If this proportion allow us to estimate the probability of next year colds, we have:

P(colds)=\frac{200}{1000} =0.2

If we take only the ones that are involved in excercise programs, we have 50 cases of cold out of 500 employees (half of the total employees).

The probabillity of cold for them is then:

P(cold\,|\,exercise)=\frac{50}{500}=0.1
