Answer:
Q, R
Step-by-step explanation:
All of the listed sets of numbers are Real numbers. The fraction is not an integer, so is not in sets I or N. Because it is a fraction, it is in set Q, and because R includes Q, ...
the number is in sets Q and R
Let's expand the products they are all in the form

For the first one we have a=x and b=2i:

For the second one we have a=x-2 and b=2i:

For the third one we have a=x+1 and b=i:

<h2><u>A = 4</u> is the correct answer!</h2><h3></h3><h3>3 x ? = 12</h3><h3>12 ÷ 3 = 4</h3><h3>so</h3><h3>1 x 4 = 4</h3><h3 /><h3>You're wrong. It is not six.</h3><h3>By the way, it's "one" not "won".</h3><h3>It was probably a mistake.</h3><h3>:)</h3><h3 /><h3><em>Please let me know if I am wrong.</em></h3>
Answer:
I believe the answer is neither
Step-by-step explanation:
Answer:
1) The probability that the mean mpg for a random sample of 25 light vehicles is 0.042341.
2) between 20 and 25 --> 21-25/2.9 = -1.38
Step-by-step explanation:
Problem #1:
- Using the z-score formula, z = (x-μ)/σ/n, where x is the raw score = 20 mpg,μ is the population mean = 21 mpg , σ is the population standard deviation = 2.9, n = random number of samples.
<h3><u>X < 20</u></h3>
- = z = 20 - 21/2.9/√25
- = z = -1/2.9/5
- = z = -1.72414
<h2><u><em>Now</em></u></h2>
<em>P-value from Z-Table:</em>
<h3><u>P(x<20) = 0.042341</u></h3>
Problem #2:
<h3>21-25/2.9 = -1.38</h3>
