All you need to do is find the frequency of the test scores.
70 = 2 dots
75 = 0
80 = 3 dots because there are 3 students that got a 80 %
85 = 3 dots because there are 3 students that got a 80 %
90 = 4 dots because there are 4 students that got a 90 %
95 = 3 dots
100+ = 0 dots
An earthquake with a rating of 3.8 can cause destruction in areas of up to 100 kilometers that are populated.
<span>R = log x </span>
<span>R = rating of the earthquake's size on the Richter scale </span>
<span>x = ratio of earthquake intensity to a minimum level of intensity</span>
Step-by-step explanation:
Z - 0.72 = - 2.5
Z = - 2.5 + 0.72 = - 1.78
Z = - 1.78
12 times 2 + 9 times 2 = 24 + 18 = 42 divided by 16 = 2.625
