Answer:
3 2/5
Step-by-step explanation:
8-3x4
ok well do 3x4 that is 12
so do 12 minus 8 which is 4. and 4 as a fraction is 2/5 so
do 6/2 plus 2/5
which is.....
.....
3 and 2/5
Answer:
cos(θ)
Step-by-step explanation:
Para una función f(x), la derivada es el límite de
h
f(x+h)−f(x)
, ya que h va a 0, si ese límite existe.
dθ
d
(sin(θ))=(

Total number of Pizzas sampled = 344+391+155+185 = 1075
No. of Thick crust Pizzas in sample = 391
Proportion of Thick crust Pizzas in sample = 391/1075
Expected number of Thick crust in next 3500 pizzas = 3500*(391/1075)
Expected number of Thick crust in next 3500 pizzas = 1273
Out of 3500, he may expect 1273 pizzas to be thick crust
Answer:
upper control limit = 13.34
Step-by-step explanation:
The c-chart is used to check the change in the number of recorded calls per day
First find out the center line
c = sum of recorded calls/number of days
c = (3 + 0 + 8 + 9 + 6 + 7 + 4 + 9 + 8)/9
c = 54/9
c = 6
The upper control limit for 3σ is
upper control limit = c + 3√c
upper control limit = 6 + 3√6
upper control limit = 13.34
Therefore, the upper control limit for the 3-sigma c-chart is 13.34.
