Answer:
1) Radius of the cone = 9.5 cm
2) BA = 90.25 π cm²
3) SA = 384.7 π cm²
Step-by-step explanation:
1) Radius of the cone = 9.5 cm
2) Base Area of the cone =
BA = (π)(9.5)²
BA = 90.25 π cm²
3) Surface Area of Cone =
SA = π(9.5)(9.5 + √(29.5)²+(9.5)²)
SA = 9.5π(9.5 + 31)
SA = 9.5π(40.5)
SA = 384.7 π cm²

Answer:
The 98% confidence interval for the probability of flipping a head with this coin is (0.4756, 0.7044).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of
, and a confidence level of
, we have the following confidence interval of proportions.

In which
z is the z-score that has a p-value of
.
An experimenter flips a coin 100 times and gets 59 heads.
This means that 
98% confidence level
So
, z is the value of Z that has a p-value of
, so
.
The lower limit of this interval is:

The upper limit of this interval is:

The 98% confidence interval for the probability of flipping a head with this coin is (0.4756, 0.7044).
Answer:
English to Algebra translation says that "four less than twice a number is 10" yields the equation 2N - 4 = 10 2N = 14 N = 7
Step-by-step explanation:
The ratio of rise to run between points B and C is the same as the slope of line AB
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Slope of a line = ratio of rise to run = rise / run
Hence:
The ratio of rise to run between points B and C is the same as the slope of line AB
