ANSWER

The midpoint is a) (m,n)

EXPLANATION

The point O has coordinate (0,0) and the point A has coordinate (2m,2n)

The x-coordinate of the midpoint is

x =  \frac{0 + 2m}{2}

x =  \frac{2m}{2}

x = m

Also,

y =  \frac{0 + 2n}{2}

y =  \frac{ 2n}{2}

y = n

The answer is A

I am Lyosha [343]

It is given that there are 41 males and 48 females in the small school.

So, the number of ways a male student can be chosen from 41 males is ^{41}C_1

Likewise, the number of ways a female student can be chosen from 48 females is ^{48}C_1.

Thus, the total number of ways in which 2-person combinations are possible to represent the student body at the PTSAC meetings will be given by:

^{41}C_1\times ^{48}C_1=1968

A researcher is exploring the notion that there is an economy of scale in raising children. While having one child might add to
trasher [3.6K]

Answer:

The probability is   G  =  85%

Step-by-step explanation:

From the question we are told that

   The percentage of parents that have one child under 18 in their homes is  k = 15%

  The percentage of parents that have two children is  T = 65%

    The percentage of parents that have three or more children is  Y = 20%

Generally the probability that any given family who is selected have two or more children at home is mathematically evaluated as

     G  =  T  +  Y

=>  G  =  65% +  20%

=>  G  =  85%

Last month, 17 people showed up to help a local charity. This month, 55 people volunteered. What is the percentage increase?
astra-53 [7]

Step-by-step explanation:

The formula for percent change is

change/original.

So let's subtract 17 from 55 to find the change. 55-17=38

This is the change. Now we divide it by the original, 17.

38/17=2.235294

We're not done yet! We have to move the decimal point over to the right 2 spaces to make it a percentage. So, the percentage increase is

about 223.53 percent

What is 5.8×10^6 seconds in minutes?
Wewaii [24]

Answer:

<u>9.66 x 10⁴ minutes</u>

Step-by-step explanation:

To convert seconds into minutes, simply divide by 60.

=> 5.8 x 10⁶ / 60

=> 580 x 10⁴ / 60

=> 29 x 10⁴ / 3

=> <u>9.66 x 10⁴ minutes</u>

55% of 6th grade students voted in the student election. 440 sixth grade students voted in the student election. How many total
Ne4ueva [31]

Answer:

800. Here's why:

Step-by-step explanation:

This indicats that 440 students make up 55% of the 6th grade population. We can write this as

55/440.

We also know that 'x' total students make up 100% of the 6th-grade population, so we can write this as

100/x.

55/440 must be equal to 100/x. When cross multiplied, it becomes 50x=44000. If we divided each side by 50, we'll find that x=880. Therefore, there are 800 6th graders
