When x increases from a to a + 2, y increases by a difference of 8. For which functions is this statement true?

lord [1]

Answer:

That would be Option C.

Step-by-step explanation:

Lets look at y = 4x + 2:-

Let x = a then y = 4a + 2

Now if x in creases to a +2, y = 4(a +2) + 2 = 4a + 8 + 2

= 4a + 10.

(4a + 10) - (4a + 2) = 8 , so this is the required expression, y = 4x + 2.

What is the variance of the following data? If necessary, round your answer to two decimal places 600,470,170,430,300

Mkey [24]

Answer:

72112885110079700000000000000.00

Step-by-step explanation:

X(mean) = (600470170430300 + 23056 + 22123 + 21704 + 20365) / 5 = 120094034103510

n=5

S²(variance) = ((600470170430300-120094034103510)²+(23056-120094034103510)²+(22123-120094034103510)²*+(21704-120094034103510)²+(20365-120094034103510)²/(5-1)

S² = 72112885110079700000000000000.00
