Answer:
56 packs of crazy straws
Step-by-step explanation:
1. 224 x 2= 448 *the total straws*
2. Once you have that, Divide the 448 by 8 so you can find out the packages he started with. You get 56.
3. Check your work by doing 56 x 8, which is 448, just to make sure.
4. Divide 448 by two which gives you 224, which is what you started with.
the measure of ∠1 is 92 degrees
mean=42
SD=7.8
X=54
Z=(X-u)/SD
Z=(54-42)/7.8=12/7.8
=1.54
