<span>half of the number is (1/2 N) 15 more than that is 1/2 N + 15
1/2 N + 15 =9
subtract 15 form each side: 1/2 N = -6
multiply each side by 2: N = -12

Answer:
c.145.3 to 154.7.
Step-by-step explanation:
We have to find our level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Z-table as such z has a p-value of .
That is z with a p-value of , so Z = 1.645.
Now, find the margin of error M as such
In which is the standard deviation of the population and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 150 - 4.7 = 145.3.
The upper end of the interval is the sample mean added to M. So it is 150 + 4.7 = 154.7.
Thus the correct answer is given by option c.
Answer:
as a decimal 5 2/3 would be 5.67 rounded to the nearest hundredth. As a decimal 5 1/5 5.2 to the nearest tenth.
Rohit rode his bike a greater distance because 5 2/3 is only 1/3 away, while 5 1/5 is 4/5 away.
I hope this helps!
<span>The first statement is correct. The two events are independent because Roger winning does not affect Stephan's chances. The probability that both events occur is found by multiplying the probabilities together.</span>
