Answer:
20??? wow I feel stupid I forgot how to do everything
Answer:
460
Step-by-step explanation:
This quiz is Said to consist of 920 questions. Each if these questions have 2 options of answering them only. Which is True or False.
True represents correct = 0.5
False represents wrong = 0.5
The probability of correct is = 0.5
With a sample size of 920
Mean = no
= 920x0.5
= 460
So the mean number of correct answer from this calculations I just did is equal to 460
D(√x + (1/4) sin (2x)^2)/dx = 1/(2√x) + (1/4) cos (2x)^2 * 8x = 1/(2√x) + 2x cos (2x)^2
I think they both increased by 3 and the new dimensions is 8 ft by 7 ft
