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

Answer:
123
Step-by-step explanation:
In a parallelogram, both pairs of opposite angles are congruent. Also, both pairs of opposite sides are parallel, meaning there are consecutive interior angles. Consecutive interior angles equal 180, so simply subtract 57 from 180 to find your missing angles.
To simplify, we'd simply distribute the power of 4 to each individual within the parentheses
answer = D.
Answer:
68% 32%
73.5% 26.5%
Step-by-step explanation:
Start:
total number = 561 + 264 = 825
glucose aversion = 561
percent = 561/825 × 100% = 68%
no glucose aversion: 264
percent = 264/825 × 100% = 32%
End:
total number = 441 + 159 = 600
glucose aversion = 441
percent = 441/600 × 100% = 73.5%
no glucose aversion: 159
percent = 159/600 × 100% = 26.5%
