Answer:
1/2 y - 1/3 x -1 = 0
Multiply through by the LCD -6 to clear the fractions and the negative coefficient with the 'x'.
-3y + 2x + 6 = 0
Then reorder
2x - 3y + 6 = 0

What is the question? there is only statement.
Using the normal distribution, it is found that 7.64% of of sample means are greater than 8.8 hours.
<h3>Normal Probability Distribution</h3>
The z-score of a measure X of a normally distributed variable with mean
and standard deviation
is given by:

- The z-score measures how many standard deviations the measure is above or below the mean.
- Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.
- By the Central Limit Theorem, the sampling distribution of sample means of size n has standard deviation
.
The parameters are given as follows:

The proportion of sample means greater than 8.8 hours is <u>one subtracted by the p-value of Z when X = 8.8</u>, hence:

By the Central Limit Theorem


Z = 1.43
Z = 1.43 has a p-value of 0.9236.
1 - 0.9236 = 0.0764.
7.64% of of sample means are greater than 8.8 hours.

Answer:
Step-by-step explanation:
Use PEDMAS. So first addition has to be done as it is inside parenthesis. After that multiplication has to be done
0.060 +
<u>0.008</u>
<u>0.068</u>
In decimal multiplication, first multiply the numbers ie, 2 * 68 which is 136. Then count the number of decimal places in both the multiplicands and keep the same number of decimal places in the result(136).
0.02 * 0.068 = 0.00136
