It is 629, because I used gauthmarh to translate it
<span>To check if multiple ratios are proportional, you could write them as fractions then you would have to reduce them and compare them. If the reduced fractions are all the same, then the ratios are proportional. </span>
Unit Imaginary Number The "unit" Imaginary Number (the equivalent of 1 for Real Numbers) is √(−1) (the square root of minus one). In mathematics we use i (for imaginary) but in electronics they use j (because "i" already means current, and the next letter after i is j).
-1= i
Answer:
C)3
Step-by-step explanation:
divide 3/4 by 1/4 and get 3
Answer:
P-value ≈ 0.3463
Step-by-step explanation:
Hypothesis test would be
:p=0.20
:p>0.20
We need to calculate the z-score of sample proportion and then the corresponding P-value.
z-score can be calculated as:
z= where
- p(s) is the sample proportion of specimens yield before the theoretical point ()
- p is the proportion assumed under null hypothesis. (0.20)
- N is the sample size (40)
Using the numbers
z= =0.3953
and the P-value is then P(z)≈0.3463
