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>
Answer:
4. sin 40= 0.7451131604793488384
5. cos 40= -0.666938061652261888
6. tan 50= -0.2719006119976306688
7. tan 40= -1.1172149309238962176
8. sin A= -0.5882162892399388672
9. cos A= -0.8087036521945458688
10. tan A= 0.7273570332515760128
Answer:
Without graphing, determine whether the parabola -2(3x + 5)(6 - x) opens up or down and ... Use the shortcut to write the equation for the axis of symmetry and find the ...
Step-by-step explanation:
<u> Answer I got for this was 16.
Subtract the 1/4 from the 3/4 and get 2/4, simplified: 1/2
You should have 1/2 h -9 = -1 by now,
Then add nine to the other side, getting 8.
You should have 1/2 h = 8.
Then divide 1/2 by 8.
8/1÷1/2 ---> 8/1 × 2/1 (you flip the fraction when you divide)
So your answer is 16!
Hopefully that helped!</u>
