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

What is the difference between 3/7 and 1/14<br> A 1/2<br> B 4/14<br> C 5/14<br> D 9/14

Cerrena [4.2K]

C. 5/14
You find the LCD. In this case it would be 14 since both 7 and 14 can go into 14. You have to multiply the top by the same number as the bottom. 2*7=14
2*3=6. You now have 6/14. 6-1=5
The denominator stays the same. 5/14

A is the point (70, -80) and B has coordinates (-58, 48) what is exact length of AB

Nina [5.8K]

Answer:

$128\sqrt{2}$ units

Step-by-step explanation:

We are given;

Coordinates of A (70, -80)
Coordinates of B (-58, 48)

We are required to calculate the length of AB

To determine the length of AB we are going to use the formula for getting magnitude;
Given, coordinates (x₁, y₁) and (x₂, y₂), then

Magnitude =√((x₂-x₁)²+(y₂-y₁)²)

Therefore;

Length = $\sqrt{((48+80)^{2} +(-58-70)^2})$

= $\sqrt{16384+16384}$

= $\sqrt{16384*2}$

= $\sqrt{16384} *\sqrt{2}$

= $128\sqrt{2}$

Therefore, the exact length of AB is $128\sqrt{2}$ units
