Find the surface area of a sphere with a radius of 1. Use 3.14 for π. Round your answer to the nearest tenth.
Butoxors [25]
The formula for finding the surface area of a sphere is A=4πr^{2}. Since we already have the radius, we just plug that into the equation, like so:
A = 4 x 3.14 x 1^{2}
First, following the rules of PEMDAS, do the exponent, coming out with an answer of 1. Now, multiply 4 x 3.14, which is 12.56. 12.56 x 1 = 12.56.
Rounded to the nearest tenth, your answer is 12.6.
Hope this helps!

A sample of 80 Valencia oranges showed a mean weight of 5.5 ounces with a standard deviation of 0.2 ounces. Obtain a 95% confide
BartSMP [9]

Answer:

[ 5.456, 5.544]

Step-by-step explanation:

Confidence interval can be defined as a range of values so defined that there is a specified probability that the value of a parameter lies within it.

The confidence interval of a statistical data can be written as.

x+/-zr/√n

Given that;

Mean x = 5.5 ounces

Standard deviation r = 0.2 ounces

Number of samples n = 80

Confidence interval = 95%

z value (at 95% confidence) = 1.96

Substituting the values we have;

5.5+/-1.96(0.2/√80)

5.5+/-1.96(0.022360679774)

5.5+/-0.043826932358

5.5+/-0.044

= ( 5.456, 5.544) ounces

Therefore the 95% confidence interval (a,b) = ( 5.456, 5.544) ounces
