3. b=4
Step-by-step explanation:
Answer:
P(X<1200) is 0.8212
Step-by-step explanation:
Test statistic (z) = (X - mean)/sd
X is score of a tester = 1200
mean = 1497
sd = 322
z = (1200 - 1497)/322 = -297/322 = -0.92
The cumulative area of the test statistic is the probability that X<1200. The cumulative area is 0.8212.
Therefore, P(X<1200) = 0.8212
x/5(10-11) Remember PEMDAS and remember to isolate the variable;)
1. x/5(10-11) =2 (subtract)
2. x/5 * -1 =2 (add +1 to each side)
3. x/5= 3 (multiply both sides by five)
4. x=15
