Answer:

add both x coordinates and divide them by 2.

add both y coordinates and divide them by 2.

Now final product should be (x,y)

Step-by-step explanation:

Example.

let's take 2 points:

(2,5) and (7, 9)

let's add both x coordinates.

2+7 = 9

now add both y coordinates.

5+9 = 14

Now divide both by 2.

Final answer should be (4.5, 7) = this is your midpoint

elixir [45]

Answer:

The answer to your question is below

Step-by-step explanation:

See the picture, please

In the first picture, we notice the initial amount of brownies (7/10), 7 brownies in a pan for 10 brownies.

After Tyreese bought 2/5 (7/10 - 2/5 = 3/10) there are 3 brownies left.

So in the picture, we notice only 3 brownies in a pan for 3 brownies.

The number of orders received daily by an online vendor of used CDs is normally distributed with mean 270 and standard deviation

frez [133]

Answer:

Step-by-step explanation:

Given that the number of orders received daily by an online vendor of used CDs (say X) is normally distributed with mean 270 and standard deviation 16.

X is N(270, 16)

To find percentage of days will the company have to hire extra help or pay overtime, we can find probability using std normal table

X>302 means

$Z>\frac{302-270}{16} =2$

P(Z>2) = 0.25

Thus 25% of days will the company have to hire extra help or pay overtime
