Answer:
choice D.) 0.9429
Step-by-step explanation:
Given a Normal data set
mean u = 54
standard deviation s = 3.8
we want P( X > 48)
Standardize this probability so we can use Z-scores.
P( X > 48) = P( (X - u)/s > (48 - 54)/3.8 ) = P(Z > -1.5789)
so I look for P ( Z > 1.5789) = 0.0571
so P(Z > -1.5789) = 1 - P(Z > 1.5789) = 1 - 0.0571 = 0.9429
So remember range means subtract from least number from the greater number in the set.
so the smallest number in the set is 0 and the biggest number is 18.
18-0=18
Range=18

Step 3....because a number has been added only to one side of the equation
True.
A diameter is a line that goes across the whole circle and passes by the center.
A chord is any line segment that connects two points on the circumference.
Since the diameter is a line from one opposite end of the circle to the other, it is connect two points on the circumference, thus it is a chord.
2/3 x - 5 = 21
2/3 x = 21 + 5 = 26
x = 26 / 2/3 = 26 * 3 /2 = 78/2 = 39
