Answer:
The correct explaination is Point G can be the centroid because 12:6 equals 2:1
Step-by-step explanation:
Given in triangle ABC, the segments drawn from vertices intersect at point G.
Segment FG measures 6 cm and and segment FC measures 18 cm.
FG = 6 cm & FC = 18 cm
and also FC = FG + GC
18 = 6 + GC ⇒ GC = 12
Note: The centroid divides each median in a ratio of 2:1
& 12:6 give rise to 2:1
Hence, the correct explaination for this is Point G can be the centroid because 12:6 equals 2:1
Answer:
Option D, ∠FBE
Step-by-step explanation:
The image for the question is attached herewith
Solution
As per the property of arc, angles subtended by the same arc (chord) on the circumference of a circle have equal measures.
∠FAE is an angle subtended by the arc FE that touches the circle at point 'A'.
∠FBE is also subtended by the arc FE at the point 'B'.
Therefore, we must have
m∠FAE = m∠FBE.
Since, m∠FAE = 72°, so m∠FBE = 72°.
Hence, option D, ∠FBE
Answer:
The best recommendation is to: Increase the sample size.
Step-by-step explanation:
The width of a confidence interval ,depends on three things,
- Sample size (n)
- Standard deviation
- Confidence level
To decrease the width the following options can be used:
- Increase the sample size.
Since the sample is inversely proportional to the width of the confidence interval, increasing the value of <em>n</em> will decrease the width.
- Decrease the standard deviation.
The standard deviation is directly proportional to the width of the confidence interval. On decreasing the standard deviation value the width of the interval will also decrease.
- Decrease the confidence level.
The critical value of the distribution is based on the confidence level. Higher the confidence level, higher will be critical value.
So, on deceasing the confidence level the critical value will decrease, hence decreasing the width of the interval.
Thus, the best recommendation is to: Increase the sample size.
Okay here we go. The diameter is 8, therefore the radius is 4. so you plug in 4 to r. 2pi4.
i believe it is 25
The LCM of 15 and 50 is 150
