First find the slope by calculating rise (change in x) over run (change in y).
(4/5)-0/0-(-5)
(4/5)/5=0.16
The y intercept is 4/5. We know this because y interceot is the value of y when x is 0.
Then plug this into y=mx+b where m is slope andb is y intercept.
Final answer: y=0.16x+0.8 or y= 4/25x+ 4/5
Where is the cubic figure? But just to let you know for future reference there are calculators for that all you have to do is put in the dimensions! ;)
Based on the given description above, the answer for this would be the term DEMAND. Demand is defined as the consumers' <span>willingness to pay depends on what income and prices of related goods. Hope this is the answer that you are looking for. Have a great day ahead!</span>
Answer:
57
Step-by-step explanation:
Given that :
Standard deviation (σ) = 5 minutes = (5 *60) = 300 seconds
Margin of Error, E = 78
Assume a confidence interval of 95%;
Using the relation :
((Zα/2 * σ) / E)²
(1 - α)/2 = (1 - 0.95)/2 = 0.05 /2 = 0.025
Z0.025 = 1.96
Sample size = ((1.96 * 300) / 78)²
Sample size = (588 / 78)^2
Sample size = 7.5384615^2
Sample size = 56.828
= 57 samples
The answer is
96%.
Explanation:
It is generally presumed that the scores are normally distributed.
1) You are given how many standard deviations from the mean Jeremy's score is. This is exactly the definition of the
z-score. Therefore z = 1.75
2) Look at a left-tail z-table in order to find the area of the normal curve on the left of your z-score (see picture attached). A = 0.9599
3) Multiply the area by 100 in order to find the
percentile:
<span>0.9599 </span>× 100 = 95.99
Therefore, 95.99% of the students scored less than Jeremy.
Hence, the answer is
96%.
