Answer:
there is no answer to that
Step-by-step explanation:
what do you mean by that.
Answer:
The statue is 12 meters taller than Anakka.
Step-by-step explanation:
Use the Pythagorean Theorem which is a^2+b^2=c^2. The length is b. You know that the statue in Dover Park is 16 miles away so that is b. You know that the hypotenuse is 20 so that means the equation will be a^2+16^2=20^2. Simplify this to get a^2+256=400. Simplify this to get a^2=144. Divide each side by squared so that means a=square root of 144 which is equal to 12. Therefore, the statues is 12 meters taller than Anakka.
Answer:
x=31
<c = 93
Step-by-step explanation:
The sum of the angles of a triangle is 180 degrees
<a +<b + <c = 180
35+ 52+3(x+2) = 180
Combine like terms
87+3(x+2) = 180
Subtract 87 from each side
87-87 +3(x+2) = 180-87
3(x+2) =93
Divide each side by 3
3(x+2)/3 = 93/3
x+2 = 31
Subtract 2 from each side
x+2-2 = 31-2
x = 29
Substitute x into the expression for angle c
<c = 3(x+2)
=3(29+2)
= 3(31)
=93
Answer:
Option a) A 95% confidence interval for the mean diameter of the 120 bearings in the sample is .
Step-by-step explanation:
We are given the following information in the question:
Sample size, n = 120
Sample mean = 10 mm
Standard Deviation = 0.24 mm
Formula:
Hence, the correct interpretation for the confidence interval is given by option a).
A 95% confidence interval for the mean diameter of the 120 bearings in the sample is .
We have to consider the factor of sampling of 120 ball bearings from a population of 10,000 ball bearings.
