2.5 b = 27.5
b = 27.5 / 2.5
b = 11
26 / 8 = 3.25;
14 / 4 = 3.50;
The mistake is obvious !
Answer:
the answer is below
Step-by-step explanation:
We have the total number of possible samples = 4 * 4 = 16 (As 4 choices for each value)
in addition we have to as all sample occur with equal probability, probability of each sample = 1/16, below is samling distribution of mean
x1 x2 probabilityP(x1,x2) sample mean
190 190 1/16 190
190 100 1/16 145
190 272 1/16 231
190 74 1/16 132
100 190 1/16 145
100 100 1/16 100
100 272 1/16 186
100 74 1/16 87
272 190 1/16 231
272 100 1/16 186
272 272 1/16 272
272 74 1/16 173
74 190 1/16 132
74 100 1/16 87
74 272 1/16 173
74 74 1/16 74
Summarizing above with adding duplicate values
sample mean probability
74 1/16
87 1/8
100 1/16
132 1/8
145 1/8
173 1/8
186 1/8
190 1/16
231 1/8
272 1/16
Answer:
Hello Adam Here!
Step-by-step explanation:
When multiplying by powers of 10, move the decimal point one place to the right for each power of ten. 2. When dividing by powers of 10, move the decimal point one place to the left for each power of ten. The following diagram shows how to multiply and divide numbers by powers of 10.
Hope This Helps From, Adam :)
