Please I need help on question #4!!

Mathematics
1 answer:
Otrada [13]3 years ago
5 0

Answer:

(a) 2,481,115 ways

(b) 1 way

(c) 2,572,999 ways

Step-by-step explanation:

<em><u>a</u></em> = we select 3 units from 250-3 = 247 nondefective units.

<em><u>b</u></em> = since there is a different order of the units that will lead to  the same units being selected, the order isnt actually important and therefore we really just need to use a combination. We have to select 3 unis from 3 defective units.

<em><u>c</u></em> = we select 3 units from 250 units

<u><em>Brainliest please, I need 4 more :P</em></u>

Find the 50th term of the following<br> arithmetic sequence 5, 9, 13, 17?
yarga [219]

Answer:

201

Step-by-step explanation:

First you need to know the position to term rule and to find this you use a formula which is:

tn = an + b

Where tn is the term number,  a is the difference between the other terms.

So the tposition to term rule here is 4n+1.

Then we substitute n for the value 50 making it 4(50) + 1 = 201.

201 is the 50th term

A 5 ounce bottle of juice cost $1.35 and an 8 ounce bottle of juice cost $2.16 a what is the unit cost per ounce of juice and b
lorasvet [3.4K]

Answers:

First bottle's unit cost = 27 cents per oz

Second bottle's unit cost = 27 cents per oz

Both have the same unit cost.

----------------------------------------

Work Shown:

unit cost = price/(number of ounces)

1st bottle unit cost = (1.35)/(5) = 0.27 dollars per oz = 27 cents per oz

2nd bottle unit cost = (2.16)/(8) = 0.27 dollars per oz = 27 cents per oz

Both lead to the same unit cost. Therefore, you can pick either option and it doesn't matter.
