Answer is approximately 1.07 lbs, You divide 14 pounds into the 13 bags of popcorn to get the weight of each bag
Given:
Population mean, μ = 10
Population standard deviation, σ = 1.5
Random variable, x = 11.
By definition, the z-score is
z = (x - μ)/σ
= (11 - 10)/1.5
= 0.667
Answer: 0.667
Answer:
21/4
Step-by-step explanation:
Rate of change also means slope.
Pick any two points, for example (8,167) and (12, 188)
Now use the formula y2-y1/x2 - x1 to find slope
188 - 167/ 12 - 8
21/4
The rate of change is 21/4, <em>note you would NOT convert the fraction into to a decimal until your teacher specifies you to.</em>
W = L - 15
WL = 76
(L-15)L = 76
L^2 - 15L - 76 = 0
(L-19)(L+4) = 0
L = 19 or -4
Since a length cannot be negative, the length must be 19 units.
The width is 19-15=4 units.
