According to the National Education Association (NEA), teachers generally spend more than hours each week working on instruction

VladimirAG [237]

Answer/Step-by-step explanation:

=>Given the no. of hrs a sample of high school Science and English Teachers spend on instructional duties weekly as follows:

Science teachers: 53 56 54 54 55 58 49 61 54 54 52 53 54

English teachers: 52 47 50 46 47 48 49 46 55 44 47

=>Required:

a. Median number of hours worked by Science teachers weekly:

First step to take is to arrange our given data in ascending order as follows =>

49, 52, 53, 53, 54, 54, (54), 54, 54, 55, 56, 58, 61

Next is to find our median which is the the middle value of our data point = 54

b. Median number of hours worked by English teachers weekly:

First, order the data given as follows =>

44, 46, 46, 47, 47, (47), 48, 49, 50, 52, 55

Next is to find the middle data point = 47

C. The group with the highest median number of hours is Science Teachers = 54 hours per week

The difference in the median number of hours worked per week between both groups = 54 - 47 = 7hours

How many solutions does the system of equations have?

statuscvo [17]

5x - 20y = 60...reduce by dividing by 5
x - 4y = 12
this is the same as the other equation....therefore, it is the same line...meaning infinite solutions
=============
y - 7x = -14
y = 7x - 14.....slope = 7, y int = -14

7y - 49x = -2
7y = 49x - 2
y = 7x - 2/7.....slope is 7, y int is -2/7

if the slopes are the same, but the y int are different, then u have a parallel lines with no solutions

Answer:

Red circle: 30 cm

Blue circle: 60 cm

Step-by-step explanation:

The circle's circumference is calculated with

$d \times \pi$

They want you to make it <em>about</em> how long it is so instead of pi we can just use 3 (since pi is about 3,14). The diameter (d) is double the ratio.

So now we just put in the numbers.

For the red one

$10 \times 3 = 30$

The circumference is about 30 centimetres.

For the blue one

We know the ratio of the smaller so we just add together the small ratio with the rest of the length that we know so the blue one's ratio is 10 cm. (5+5=10)

And now we just put the numbers in again.

$20 \times 3 = 60$

The circumference is about 60 centimetres.
