Answer:
A) <SQT = 36 degrees
B) <QRW = 36 degrees
C)<PRV = 72 degrees
Step-by-step explanation:
A) <SQT = 36 degrees (< SQT and < PQR are<em> vertically opposite angles</em>, and vertically opposite angles are equal)
B) <QRW = 36 degrees ( <QRW and < SQT are <em>corresponding angles</em> since they lie on the same side of the transversal across the parallel lines. Corresponding angles are equal)
C)<PRV = 72 degrees( <PRV is the <em>exterior base angle </em>to < PQR and exterior base angles, are always twice their interior correxpondents)
Answer:
The correct option is a)
05; .73; .27 , type 1 error, type 11 error and the power of the test respectively.
Step-by-step explanation:
Alpha is the probability of a type 1 error, given the null hypothesis is true. Therefore alpha= 0.05
Type 11 error is the probability of accepting a false null hypothesis.
Beta= 0.73
The Power of a test is the probability of rejecting the null hypothesis, given it is false
Power= 1- beta
Power= 1-0.73
Power= 0.27
Therefore the type 1 error is 0.05
The type 11 error is= 0.73
The power of the test= 0.27
The right option is a)
Answer:
The number of students who took English and History, but not Math is 143.
Step-by-step explanation:
Denote the subject choices as follows:
<em>M</em> = a students was taking Math
<em>E</em> = a students was taking English
<em>H</em> = a students was taking History
The data provided is as follows:
N (M) = 257
N (E) = 282
N (H) = 323
n (M ∩ E) = 154
n (M ∩ H) = 171
n (E ∩ H) = 143
n (M ∩ E ∩ H) = 80
Consider the Venn diagram below.
From the provided data and the Venn diagram the value of the set E and H minus M is 143.
Thus, the number of students who took English and History, but not Math is 143.
