Answer:
1.5kg
Step-by-step explanation:
The mean for the packages on day 1 will be:
= (1 + 8 + 1 + 12 + 1 + 11 + 7 + 6)/8
= 47/8
= 5.875
The mean for day 2 will be:
= (47 + 12)/8
= 59/8
= 7.375
The increase in mean:
= 7.375 - 5.875
= 1.5
a²=15²-9²
a²=225-81
a²=144
a=12
114
z = (x − μ) / σ
0.93 = (x − 100) / 15
x ≈ 114
finger it out
5/6 % 1/2 you flip the 1 and 2 so it will look like 2/1 then you multiply the fractions together
5/6 % 2 you make the 2 a frustration like 1/2 then you multiply 5/6 and 1/2 together
