In the given question, it is already disclosed that the typing speed of Finke has increased from 40 words per minute to 45 words per minute. Now we have to find the percentage increase in the speed of typing.
For this purpose we have to find the solution in the method described below.
Number of increase in words typed per minute = 45 -40
= 5
Then Percentage increase in the speed of typing by Finke = (5/40) * 100
= (1/8) * 100
= 25/2
= 12.5
So the percentage increase in the typing speed of Finke is 12.5%. I hope this has answered your question and the description used to solve this problem is understandable.
Answer:
(2,3) becomes A'(-2,-3)
Step-by-step explanation:
Using the 180 cc rotation rule (x,y) --> (-x,-y). Points 2 and 3 become negative resulting in (-2,-3)
These are the answers. You subtract 6 from -3 giving you n≥-9. Since n/3 is a fraction, in order to undo it we must multiply it to the other side, giving us n≤-63.
1. n≥-9
3. n≤-63
I hope it helped!
So, and, but, but, or, nor, so. Im pretty sure this is correct.
Answer:
The probability is 0.9938
Step-by-step explanation:
In this question, we are asked to calculate the probability that the mean blood pressure readings of a group of people is less than a certain reading.
To calculate this, we use the z score.
Mathematically;
z = (mean - value)/(standard deviation/√N)
From the question, we can identify that the mean is 125, the value is 123 , the standard deviation is 9.6 and N ( total population is 144)
Let’s plug these values;
z = (125-123)/(9.6/√144) = 2.5
Now we proceed to calculate the probability with a s score less than 2.5 using statistical tables
P(z<2.5) = 0.9938
