Answer:
18 miles
Step-by-step explanation:
Well, the problem did say a taxi ride costs $3 plus $2 for every mile. So, $39-3=$36, then, 36÷2=18 miles
The general rule for a linear equation is y=mx+c where m is the slope or gradient... therefore the slope is 3.
Now we need to get 2 points on the line.
You can easily get the y-int by substituting x=0 into the equation... therefore the y-int is 11... you have one point on the line: (0,11)
Now that you have one point and we know the gradient or slope which is 3, go from the point you have found (0,11) and go up 3 and across 1 to find a second point... then simply rule a line in between the two points.
Kaine has 25 animals. 8 are cats.
Place 8 over 25
8/25. Divide.
8/25 = 0.32
0.32 = 32/100 = 32%
32% is your answer
hope this helps
Answer:
a) mean = u = 83
b) Your friend's score is 1.625 standard deviations below the mean
Step-by-step explanation:
Note:
- The correct question is as follows:
" In the Social Psychology course, you receive a score of 77 on the second exam. You are told that the standard deviation of the second exam is 8 and that your score is .75 standard deviations below the mean. "
Find:
a.What is the class mean of the second exam?
b.Your friend scored a 70 on the second exam. How many standard deviations below the mean is your friend’s score?
Solution:
- The class mean can be calculated by using the given data of your score being 0.75 standard deviation less than mean:
Your score = mean - 0.75*standard deviation.
- Plug in the values:
77 = mean - 0.75*8
mean = u = 83
- Now your friend has a score of 70 on second exam, using the above relation again we have:
Friend's score = mean - a*standard deviation.
Where, a is the constant to be found:
70 = 83 - a*8
a = (70 - 83 ) / -8
a = 1.625
- Your friend's score is 1.625 standard deviations below the mean
