Answer:

$141.33

Step-by-step explanation:

25% of 400 is 100

$100 to his friend and $158.67 to the other friend

100+158.67= 258.67 to his friends all together

(His money before)--> $400-$258.67<---(The money he gave)

=$141.33

Refer to the following frequency distribution of days absent during a calendar year by employees of a manufacturing company:
adelina 88 [10]

Answer:

(a) 91 employees were absent fewer than six days.

(b) 22 employees were absent more than five days.

(c) 20 employees were absent from 6 up to 12 days.

Step-by-step explanation:

The data for the number of days absent during a calendar year by employees of a manufacturing company is given below.

(a)

The number of employees that were absent for fewer than six days is =

Frequency\  for\  class\ [0\ - \ 3]+Frequency\  for\  class\ [3\ - \ 6]\\=60 +31\\=91

Thus, there were 91 employees who were absent for fewer than six days.

(b)

The number of employees that were absent for more than 5 days is =

Frequency\  for\  class\ [6\ -\ 9]+Frequency\  for\  class\ [9\ -\12]+\\Frequency\ for\  class\ [12\ - \15]\\=14+6+2\\=22

Thus, there were 22 employees who were absent for more than 5 days.

(c)

The number of employees that were absent from 6 up to 12 days is =

Frequency\  for\  class\ [6\ -\ 9]+Frequency\  for\  class\ [9\ -\12]=14+6\\=20

Thus, there were 20 employees who were absent from 6 up to 12 days.

The equation of line 2 is y = 4x - 7. Find line 1 given that line 1 is parallel to line 2 and has y-intercept (0,2).
MakcuM [25]

Answer:

hi! this may all seem confusing but don't worry it's easy once you get it!

so we have a line this line y=4x-7 is what we will use to plugin our point

and (0,2) is your point!

2=4(0)+b

2=b

and usually you don't have to do that (HINT: if it's 0,a number it's already b like the number that isn't 0 is b aka the y intercept)

y=4x + 2 would be the answer!

REMEMBER: Parallel is always the same so you will use the SAME SLOPE!

Well what is the slope? Slope is always mx! you can find it using the slope formula if it is not given, like this equation it was given

If this said PERPENDICULAR then it would be negative reciprocal of your slope and same equation!

hope this helps :)

new question:  write an equation of the line that contains the point (1,5) and have the same y-intercept as the line 2x+3y=6

so we need to move this from standard form to slope intercept

2x + 3y=6

-3y= -2x + 6

y= 2/3x - 2

now we've solved!  our y intercept is now -2 and slope is 2/3x

okay and now let's plug it in!

again let's plugin our point

5= 2/3 (1) + b

4 1/3= b

so! y= 2/3x - 4 1/3
