Step-by-step explanation:
16= 2×2×2×2=2^4
(I just put this here because I needed 20 characters so yeah...)
Answer:
The answer is "
"
Step-by-step explanation:
For the +4 sample proportion
Sample percentage measurements estimated stdev
![= \sqrt{\frac{[(0.45)(1-0.45)]}{[(16+4)]}}\\\\ = \sqrt{\frac{[(0.45)(0.55)]}{[(20)]}}\\\\ = \sqrt{\frac{0.2475}{20}}\\\\= \sqrt{0.012375}\\\\=0.111](https://tex.z-dn.net/?f=%3D%20%5Csqrt%7B%5Cfrac%7B%5B%280.45%29%281-0.45%29%5D%7D%7B%5B%2816%2B4%29%5D%7D%7D%5C%5C%5C%5C%20%3D%20%5Csqrt%7B%5Cfrac%7B%5B%280.45%29%280.55%29%5D%7D%7B%5B%2820%29%5D%7D%7D%5C%5C%5C%5C%20%3D%20%5Csqrt%7B%5Cfrac%7B0.2475%7D%7B20%7D%7D%5C%5C%5C%5C%3D%20%5Csqrt%7B0.012375%7D%5C%5C%5C%5C%3D0.111)
Calculating the critical z for a=0.1, two-tailed = 1.64
Calculating the confidence interval:
$141, this is because 235 divide by 10 is 23.5, multiply 23.5 by 6 and your answer is $141
Answer:
1350
Step-by-step explanation:
1000 to 1100 is an increase of 100 bacteria per 6 hours
100/6 = 16.67 bacteria per hour
16.67 * 15 hours = 250
Total bacteria should be 1100+250= 1350
hope this helps :D
Answer:
14) Not a function 15) Function 16) Function
Step-by-step explanation:
The vertical line test is when you draw a line on the graph to see if it passes the function. The rule is that you can only have one intersection per line
for number 14, if you draw a line, it intersects the function twice each time
for 15, no matter what kind of vertical line you draw, each line will only intersect the function once and the same for 16 (except 16 is more of a linear function)
