Answer: option C is the correct answer.
Step-by-step explanation:
The television costs $1,350. Chuy decides to save the same amount of money each week, for 27 weeks. After 8 weeks Chuy saved $440. This means that the amount that she saved per week is
440/8 = $55
If she saves $55 in 8 weeks, the number of weeks left is
27 - 8 = 19 week
Amount that she would save in 19 weeks is
19 × 55 = 1045
Total amount saved in 27 weeks is
1045 + 440 = $1485
Therefore, the conclusion that you can make about Chuy's plan is
C. Chuy will save more than he needs and will meet his goal in less than 27 weeks.
Answer:
0.15866 is the probability of the average fracture strength of selected 100 pieces of glasses that of exceed 14.3.
Step-by-step explanation:
Given that, the strength of a tempered(x) a glass has average 14.1 and has standard deviation 2.
,
n=number of selected pieces= 100.
The probability that the average fracture strength of 100 pieces of this glass exceed 14.3 is
= 1 - 0.84134
=0.15866.
