Answer:
Step-by-step explanation:
48) 3 numbers
49) each output or y value is going up 1.5 times so 7 is your answer
50)
n is going to equal the amount of paper karen needs.
karen will need 2250 pieces of paper.
500/50= karen can print 10 reports.
500x4=2000 sheets of paper in 4 packages.
51) (2,4) (x,y)
52) point f (1,0) (x,y)
Answer:
Lyrics A
Step-by-step explanation:
Problem statement does not mention anything about conditions of the test, so we dont know if the experiment was correctly done, but we know the kind of problem we are facing here is concerning a normal distribution
Then assuming the test was done by knowledgeable people, which means:
- they got correct information from the population
-sample was big enough
- level of confidence was acceptable for the test ( approximately 95 %) - Alternative hypothesis took into account two tails test
-Test was evaluated according to sample size
-And finally calculations were right
Under the above mentioned conditions, they tested the hypotesis H₀ = μ₀ = 16 ounces and they got results that implies the acceptance of such hypothesis (that means the null hypothesis should not be rejected), and the answer is lyrics A
Answer:
f(-2) = 3.
Step-by-step explanation:
Reading off the graph, f(-2) = 3.
Answer:
A task time of 177.125s qualify individuals for such training.
Step-by-step explanation:
Problems of normally distributed samples can be solved using the z-score formula.
In a set with mean 
and standard deviation 
, the zscore of a measure X is given by
After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X. Subtracting 1 by the pvalue, we This p-value is the probability that the value of the measure is greater than X.
In this problem, we have that:
A distribution that can be approximated by a normal distribution with a mean value of 145 sec and a standard deviation of 25 sec, so 
.
The fastest 10% are to be given advanced training. What task times qualify individuals for such training?
This is the value of X when Z has a pvalue of 0.90.
Z has a pvalue of 0.90 when it is between 1.28 and 1.29. So we want to find X when 
.
So
A task time of 177.125s qualify individuals for such training.
