Alotion is made from an oil blend costing $1.50 per ounce and glycerin costing $1.00 per ounce. four ounces of lotion costs $5.50. which value could replace x on the table? (4 – g) 1.5 (4 – g) + 1.5 4g – g(1.5) (4 – g)g

Given : An oil blend costing = $1.50 per ounce.

Glycerin costing = $1.00 per ounce.

In the given options g variable is taken.

So, let us assume number of ounces of glycerin = g ounces.

We are given, "Four ounces of lotion costs $5.50."

Therefore, total quantity of the lotion is given = 4 ounces.

Expression for number of ounces of oil blend = Total ounces of the lotion 4 - number of ounces of glycerin = (4 - g) ounces.

Cost per for (4 - g) ounces of oil blend = Number of ounces of oil blend * Oil blend costing per ounce.

Therefore, Cost per for (4 - g) ounces of oil blend = (4-g)*1.50

Therefore, (4-g)1.50 could replace x on the table.

Therefore, first option  (4 – g) 1.5 is correct option.

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.
