Ok so the first one is
1.x=135
2.x=-23
3.x=3
4.x=70
Answer: 4x
Step-by-step explanation: Move all terms that don't contain y to the right side and solve. y = 4x
<span>Maybe xy is also given ........................</span>
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
