Answer:
B. The evidence is very strong - there is NO difference in the proportion of Republicans between the two areas of town.
Step-by-step explanation: Generally, a p-value of less than 0.05 is described as a strong evidence in favour of the null hypothesis. A p-value also known as the probability value is also known to provide the smallest level of evidence at which the null hypothesis would be rejected.
In the question, The p-value is 0.105 which is bigger in value than 0.05 which means there is no significant difference between the evidence and the null hypothesis.
Step-by-step explanation:
2πrh+2πr²=surface area
2π(3)(6)+2π(3²)
36π+18π
54π
convert all to a common ratio
24 1/6
30 3/6
36 2/6
(24+30+30+30+36+36)/6
186/6
the expected value is 31.
Answer:
C. 0.6625 square inches
Step-by-step explanation:
To get the area of the net of a square pyramid;
We need to find the are of the square base and the area of the four triangles;
Area of the square base = s²
= (0.25 in)²
= 0.0625 in²
Area of one triangle = 0.5 × b × h
= 0.5 × 0.25 in × 1.2 in
= 0.15 in²
Area of the four triangles = 0.15 in² × 4
= 0.6 in²
Therefore;
Area of the net square pyramid = 0.0625 in² + 0.6 in²
= 0.6625 square inches
