Answer:
(a) 0.85
(b) 0.7225
Step-by-step explanation:
(a) The point estimate for the proportion of all such components that are not defective is given by the number of non-defective units in the sample divided by the sample size:
The proportion is 0.85.
(b) Assuming that the sample is large enough to accurately provide a point estimate for the whole population, this can be treated as a binomial model with probability of success (non-defective part) p = 0.85. Since both components must be non-defective for the system to work, the probability of two successes in two trials is:
An estimate of 0.7225 for the proportion of all such systems that will function properly.
Answer:
What percent of the school are girls? 55%
What percent of the school are boys? 45%
How many boys are there? 162
How many girls are there? 198
Step-by-step explanation:
The number of girls = 198
The percent of girls = 198/360 x 100% = 55%
The number of boys = 360-198 = 162.
The percent of boys = 162/360 x 100% = 45%.
Answer:
Your answer would be C)1,350 mm
Step-by-step explanation:
face area = (15 mm)² = 225 mm²
cube area = 6 × face area = 6×225 mm² = 1350 mm²
Answer:
c) The golf ball will travel 260.8 yards.
d) Hence the residual is 4.2 yards.
Step-by-step explanation:
c) y' = 2.8333x - 22.4967
Now the golf ball will travel 
= 260.8 yards
here y'= 260.8 yards.
d) The residual is : y - y' = 265 - 260.8 = 4.2 yards.
The answer to #1 is C. The answer to #2 is 9 checks. Hope that helps! :)
