300,000 because you have to just multiply 150 by 200
Answer:
c
Step-by-step explanation:
because all the x values in c are different
The applicable choices are ...
2x +y ≥ c
y ≥ -2x +c
Answer:
True
Step-by-step explanation:
Margin of error of a confidence interval:
The margin of error of a confidence interval has the following format:
In which z is related to the confidence level(the higher the confidence level the higher z is), s is related to the standard deviation and n is the size of the sample.
A higher confidence level leads to a larger margin of error, that is, a wider interval. The interval expands around it's lower and upper bounds, which means that if a value is part of a lower confidence interval(such as 95%), it will be part of the higher(such as 99%), and the answer to this question is true.
Answer:
a. lts diameter = 13.540550005146 cm
b. Its circumference = 42.538892421732 cm
Step-by-step explanation:
suppose A the area ; d the Diameter ; P the circumference and r the radius
A = πr²
P = d×r = 2πr
then
r² = A/π = 144÷π = 45.836623610466
then
→ r = √(45.836623610466) = 6.770275002573
d = 6.770275002573×2 = 13.540550005146
→ P = 13,.540550005146×π = 42.538892421732
