Answer:
He had $36 in the beginning
Step-by-step explanation:
We are asked to calculate how much John has after making some series of purchases. Let’s proceed.
Now, let the initial amount of money John had be $X. Let’s keep this
He initially spends 2/3 at a bookstore, the fraction unspent is 1/3. Since x is our figure, the amount unspent is $x/3
Now, he spent 1/3 of this at a craft store. This means he didn’t spend 2/3 of this and it corresponds to $8.
This mathematically means:
2/3 * $x/3 = $8
2x/9 = $8
2x = $72
x = $72/2 = $36
If I did the math correctly I’d should be -5 or rewritten as -5/1.
Answer:
0.5613
Step-by-step explanation:
Here mean strain of bacteria x = sum of all numbers/ total numbers = 0.5514 %
Standard deviation s = 0.0040 %
Test statistic
G = (x_{max} -x)/s = (0.5613 - 0.5514)/ 0.0040 = 2.475
95% confidence value for outlier for n = 8 and alpha = 0.05
G_{critical} = 2.1266
so here we see that G > G_critical , so we reject that the there is no outlier . the value of 0.5613 is and outlier.
