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
12-13= yx this is that expression
Answer:
A lies on (1,3) a reflection across the y-axis is (x,y) to (-x,y). The x turns the opposite and y stays the same so...
(-1,3)
Answer:
x=8/9
Step-by-step explanation:
5x+2(x-3)=-2(x-1)
5x+2x-6=-2x+2
7x-(-2x)-6=2
7x+2x=2+6
9x=8
x=8/9
