Answer:

X = -0.5

Y = -2.5

Step-by-step explanation:

I found this by the forumla determine the X1 and X2 add the together then divide it by 2 for the value of X midpoint. Then add Y1 and Y2 and divide it by 2 together for the value of Y midpoint.

Answer:

(-0.5,-2.5)

Step-by-step explanation:

(x1 + x2) / 2 = x midpoint
(y1 + y2) / 2 = y midpoint

⇒ 2 + -3 = 5

⇒ 5 / 2 = -0.5

⇒ 4 + -9 = -5

⇒ -5 / 2 = -2.5

→ = (-0.5, -2.5)

The distribution of the number of graduate students over the past 13 years in the math department was: 1 69 2 445 3 347 4 0269 5

Sergio [31]

Answer:

largest number os students = 73

smallest number of students is 16

Step-by-step explanation:

Distribution of student over the period of 13 year is given in the following table

first column represent the stem which are on tens digit while column 2 represent the leaf which are on one digit.

1 6 9

2 4 4 9

3 3 4 7

4 0 2 6 9

7 3

hence the graduate student number is calculated as

16, 19, 24,24,29, 33, 34,37,40,42,46,49,73.

hence from the obtained data largest and smallest number of students over a period of 13 year can be calculate

largest number os students = 73

smallest number of students is 16

Traveling math word problem - thank you! :)

Anni [7]

<u>We are given:</u>

car and train leave at the same time

average velocity of car = 50 miles/hour

average velocity of train = 70 miles/hour

train arrives 2 hours early

<u>Assuming variables and making equations!</u>

let the time taken by the train = t hours

since the car arrived late, it took more time as compared to the train

time taken by the car = t + 2 hours

since the distance from Pasadena to Sacramento doesn't change, both the vehicles covered the same distance, d

<u>Distance travelled by the car:</u>

d = 50 $\frac{miles}{hour}$ * (t+2) hours [distance = velocity * time]

d = 50(t+2) miles

rewriting in terms of t

$t = \frac{d-100}{50}$

<u>Distance travelled by the train:</u>

d = 70 $\frac{miles}{hour}$ * t hours

d = 70t miles

rewriting in terms of t

$t = \frac{d}{70}$

now we have two expressions for t, both of which are equal because t is just the time taken by the train

<u>Finding the distance:</u>

because t is the same:

$\frac{d-100}{50} = \frac{d}{70}$

$\frac{d-100}{5} = \frac{d}{7}$

7(d - 100) = 5(d)

7d - 700 = 5d

(7d - 5d) - 700 = 0 [subtracting 5d from both sides]

2d = 700 [adding 700 on both sides]

d = 350 miles [dividing both sides by 2]

The distance between Pasadena and Sacramento is 350 miles!

What is the pattern for 360,60,10

alexgriva [62]

Step-by-step explanation: Begin by studying the pattern.

Notice that if we divide the first term,

360, by 6, we get the second term, 60.

Similarly, if we divide the second term,

60, by 6, we get the third term, 10.

So each new term is equal to the previous term

divided by 2, so we use this idea to find any missing terms.
