Answer:
f(1)=-4
Step-by-step explanation:
f(1) means what is the y in the point on the curve of f so that x=1.
So I go to x=1 on the x-axis.
So I go right one from the origin.
I notice the curve is below the x-axis so I go down to the curve til I get to the curve.
Once I get to the curve, I look at the y-axis to tell what that number is for that ordered pair there at x=1.
That y-value is -4.
A graph/picture is probably worth a lot more to you then my words.

Answer:
$14.10
Step-by-step explanation:
To have 30 bulbs, Maura can buy 10 packages of 3 at $5.37 each, for a total of $53.70. Or, she can buy 15 packages of 2 at $4.52 each, for a total of $67.80.
Buying in packages of 3, Maura saves $67.80 -53.70 = $14.10.
Number 1 is 744 because if you minus the percentage form the number of songs you get the 744
Answer:
1.33 & n - 6 = 0.75(t - 8)
Explanation:
Speed can be calculated as miles ÷ minutes
4 ÷ 3 = 1.33 and 8 ÷ 6 = 1.33 as well
Since we know the n and t, we can substitute one into the equation to find the other (substitute t = 8 into all four equations and see do we get n = 6)
You can do this with t = 4 and n = 3 as well
A. yes this is a statistical question. it is a statistical question because you can answer the question by collecting data.
b. some clusters are.. 3,4,5, and 6 they are clusters because they are assembled around a particular value. the peak is 6 because it is the highest number it reaches. there are no gaps in this table.
c. to calculate the average with a graph you sum the numbers then divide by the total number of values in the set. for this table you add 1+2+3+3+4+4+4+5+5+5+5+5+5 then you divide by 15.
1+2+3+3+4+4+4+5+5+5+5+5+5=51
51 ÷ 15= 3.4
