Answer:
C. n=23; p^=0.5
Step-by-step explanation:
Normal distribution is symmetrical about the mean.
So, p should be close to ½
Solution given:
here
by using Pythagoras law
hypotenuse =
Cos C=
1 1/5 mi
We need to add the three legs together
3/10 + 1/2 + 2/5
The common denominator is 10
3/10 =3/10
1/2 *5/5 = 5/10
2/5 *2/2 =4/10
3/10 + 5/10+4/10 = 12/10
10/10 = 10/10+2/10 = 1+2/10 = 1 1/5 mi
96 is close to 100
.499 is close to .5
100 divided by .5
copy dot flip
100 * 2 =200
My estimate is 200
