Answer:

Group 2 has the greatest range

Step-by-step explanation:

From the data given we can find the range by this formula :

Range = Largest score - smallest score

Range of group 1 = 1700 - 1300 = 400

Range of group 2 = 2100 - 1250 = 850

Range of group 3 = 2000 - 1390 = 610

Range of group 4 = 2150 - 1340 = 810

400 < 610 < 810 < 850

Therefore, we can see that students of Group 2 has the greatest range.

Alina [70]

Answer:

<h2> Amount in liters is 47.9 liters</h2>

Step-by-step explanation:

The Question is incomplete, it does not provide the measurements or options to choose from, but we can estimate the answer

Step one:

Given data

Taryn Bought 12.6gallons of gasoline

1 gallon of gasoline is  3.8 liters

We want to convert from gallons to liters

Step two:

----if 1 gallon has 3.8 liters

then 12.6 gallons will have x liters

cross multiply we have

x= 12.6*3.8

x=47.88 liters

Hence the estimated amount in liters is 47.9 liters

Given 8x + 2 = 3 - x; x =
schepotkina [342]

Answer:

x = 1/9

Step-by-step explanation:

8x + 2 = 3 - x

Add x to both sides.

9x + 2 = 3

Subtract 2 from both sides.

9x = 1

Divide both sides by 9.

x = 1/9

Can someone do this aleg.2
balu736 [363]
So first we factor
9-t^2=difference of 2 perfect squares
a^2-b^2=(a-b)(a+b)
3^2-t^2=(3-t)(3+t)


t^2+t-12
factor by finding what 2 number add to get 1 and multiply to get -12
the numbers are -3 and 4
(t-3)(t+4)


[(3-t)(3+t)]/[(t-3)(t+4)] we can't factor out any further

if it was t^2-9 then we could go further but since it isn't this is the factored form
(<u><em>if</em></u> it was t^-9 then the answer would be (t+3)/(t+4))
