(12 - 9) / 12 = (40 - x) / 40
3/12 = (40 - x) / 40
40(1/4) = 40 - x
10 = 40 - x
10 - 40 = -x
-30 = -x
30 = x <=== percent decrease from 40 to 30
Answer:
t(d) = 0.01cos(5π(d-0.3)/3)
Step-by-step explanation:
Since we are given the location of a maximum, it is convenient to use a cosine function to model the torque. The horizontal offset of the function will be 0.3 m, and the horizontal scaling will be such that one period is 1.2 m. The amplitude is given as 0.01 Nm.
The general form is ...
torque = amplitude × cos(2π(d -horizontal offset)/(horizontal scale factor))
We note that 2π/1.2 = 5π/3. Filling in the given values, we have ...
t(d) = 0.01·cos(5(d -0.3)/3)
Answer:
Men can be concluded to enjoy shopping electronic activity more than women, but in weekend days. The case might not hold true for week working days also.
Step-by-step explanation:
To study : whether the percent of men who enjoy shopping for electronic equipment is higher than the percent of women who enjoy that.
- Out of 67 men, 24 said they enjoyed the activity
So, % of men enjoying the activity = (24 / 67) x 100
= 35.82%
Out of 24 women, 8 said that they enjoyed the activity
So, % of women enjoying the activity = (8 / 24) x 100
= 33.33%
