confidence interval:
This tells us the degree of certainty or uncertainty that is existent in a sampling method. It gives us a range of values, telling us we are fairly sure that our true value or parameter lies within the range.
Degree of confidence:
This tells us that the confidence interval has captured the true/exact population parameter.

Answer:
6
Step-by-step explanation:
15-8 =7 as LHS is 7 so RHS must also be 7 so at RHS 6+1 =7
X = 3
10 + 12x = 15x + 1
10 = 3x + 1
9 = 3x
3 = x
Answer:
∠ DBE = 25.5°
Step-by-step explanation:
Given ∠ DBC = 90° and ∠ DBE + ∠ EBC = ∠ DBC, then
∠ DBE = ∠ DBC - ∠ EBC = 90° - 64.5° = 25.5°
