Answer:
150
Step-by-step explanation:
75% of 200 is 150.
75*200=15000
15000/100=150
Answer:
1). m∠ACE = 115°
2). m(∠DCB) = 35°
3). m(∠ACB) = 30°
Step-by-step explanation:
In the diagram attached,
1). AB and CD are the parallel lines and the line AC is a transverse,
m(∠ABC) = 35°
m(∠BAC) = 115°
∠BAC ≅ ∠ACE [Alternate interior angles]
m(∠ACE) = m(∠BAC) = 115°
2). Since, AB and CD are the parallel lines and line CB is a transverse,
∠ABC ≅ ∠DCB [Alternate interior angles]
m(∠ABC) = m(∠DCB) = 35°
3). From ΔACB,
m(∠ACB) + m(∠CBA) + m(BAC) = 180°
m(∠ACB) + 35° + 115° = 180°
m(∠ACB) = 30°

Step-by-step explanation:
Precision describes the closeness of estimates from different samples, it refers to the width of the confidence interval and can aso be described as the margin of error. While the confidence level describes the accuracy.
Going for a higher confidence level will bring about a wider confidence interval, and thus lead to a less precise estimate.
