Answer:
see explanation
Step-by-step explanation:
The opposite angles of an inscribed quadrilateral are supplementary, thus
5x + 20 + 7x - 8 = 180
12x + 12 = 180 ( subtract 12 from both sides )
12x = 168 ( divide both sides by 12 )
x = 14
Thus
∠ RQP = 10x = 10(14) = 140°
∠PSR = 180° - 140° = 40° ( opposite angles are supplementary )
∠ SRQ = 7X - 8 = 7(14) - 8 = 98 - 8 = 90°
∠ QPS = 5x + 20 = 5(14) + 20 = 70 + 20 = 90°
Using the Central Limit Theorem, it is found that:
- The standard deviation is
.
<h3>Central Limit Theorem</h3>
- It states that for a <u>proportion p in a sample of size n</u>, the sampling distribution of sample proportions has mean
and standard deviation 
- When two variables are subtracted, the mean is the subtraction of the means, while the standard deviation is the square root of the sum of the variances.
In 2006, 95% of new cars in the US came with a spare tire, with a sample of 250, hence:

In 2017, 72% of new cars in the US came with a spare tire, with a sample of 250, hence:

Hence, for the distribution of differences:

First I would find out how many inches are burned away in 1 hour, 1 1/2 inches. then u multiply 3/4 by 4 to get 3. then u subtract the 3 by 10 to get 7 inches. the answer is 7 inches.
Assuming the whale starts at 0 inches when it is born, it took it 31.4 days to grow 47.075 inches. To find this, divide the inches grown by the rate of growth.
