The dashed line labeled as 6 is the diameter of the circular part of the figure.
The circumference of a circle is it's perimeter, so we need to find half the circumference first.
The formula for circumference is PI x diameter, since we need half we will divide the total circumference by 2.
Circumference = 3.14 x 6 = 18.85 / 2 = 9.425
Now we add that to the other 3 dimensions for total perimeter:
9.425 + 9 + 9 +6 = 33.425
You may need to round the answer, you didn't say if it needed to be rounded a certain way.
Answer:
98% confidence interval for the true population proportion of all New York State union members who favor the Republican candidate is 0.373±0.065, that is between 0.308 and 0.438
Step-by-step explanation:
Confidence Interval can be calculated using p±ME where
- p is the sample proportion of 300 union members in New York State who favor the Republican candidate ()
- ME is the margin of error from the mean
and margin of error (ME) around the mean can be found using the formula
ME= where
- z is the corresponding statistic in 98% confidence level (2.33)
- p is the sample proportion (
- N is the sample size (300)
Then ME=[tex]\frac{2.33*\sqrt{0.373*0.627}}{\sqrt{300} }[/tex≈0.065
98% confidence interval is 0.373±0.065
70 because 55+55 = 110 and a triangle is 180 so 180-110= 70 and X is opposite to the angle we worked out as the missing one
Triangle Area Formula:
0.5 * Base * Height
SO,
0.5 * 10 * Height = 45.5
5 * Height = 45.5
Height = 9.1
Answer:
72
Step-by-step explanation:
12 times 6 is 72
48 + 24 =72
