Answer:
13.1
Step-by-step explanation:
Finding mean in data set is finding the average. The way to find the average is by adding all the data in the set (the # of movies watched), then divide them by how many numbers are in the data set (7).
16+13+19+16+8+10+10=92
After you add the data in the set, you have to divide it by the pieces of data there is.
So 92/7=
13.1428571

If you round 13.142...to the nearest tenth, you get <u>13.1.</u>
Answer:
a. m = Vd
b. 6.012g
Step-by-step explanation:
a. you need to rearrange the equation so that you're solving for m. you can do so by multiplying both sides by V so you end up with
Vd = m or m = Vd (i prefer writing it this was purely cause it looks better)
b. now, you can plug in each value into the new equation so you get
5.01g/cm3 x 1.2 cm3 = m
from here you just multiply as normal
Answer:
Question 1: seems all A,B and C are incorrect
Question 2: long = 45/(3*3) =45/9 =5
We have two relations between length and width. One is given in the problem statement. The other is given by the formula for perimeter. We can solve the two equations in two unknowns using substitution.
Let w and l represent the width and length of the sign in feet, respectively.
... l = 2w -12 . . . . . the length is 12 ft less than twice the width
... p = 2(l +w) = 114 . . . . the perimeter is 114 ft
Using the first equation for l, we can substitute for l in the second equation.
... 114 = 2((2w -12) +w)
... 114 = 6w -24 . . . . . . . . simpify
... 138 = 6w . . . . . . . . . . . add 24
... 23 = w . . . . . . . . . . . . . divide by 6
... l = 2w -12 = 2·23 -12 = 34 . . . . use the equation for l to find l
The length and width of the sign are 34 ft and 23 ft, respectively.
