Answer:
E. 99.7%
Step-by-step explanation:
Calculate each z-score.
z = (x − μ) / σ
z = (173 − 128) / 15
z = 3
z = (x − μ) / σ
z = (83 − 128) / 15
z = -3
You can use a z-score table, or use the empirical rule.
P(-3 < z < 3) = 99.7%.
The best way is to use the number 3 because they would have a equal amount of kids in each group..10×3=30
So 6 people split 143.40. 143.40/6 = 23.90. Thats how much each person paid for the dinner. Add the 7.50 they paid for the movie and you would get 31.40$ total for each person. If this is right could I possibly have brainliest? Hope this helped!! :)
