Answer:
28.27 inches
Step-by-step explanation:
-Circumference of a circle is calculated using the formula:
#Substitute for radius in the formula to solve for C:
Hence, the plate's circumference is 28.27 inches
Answer:
And for this case the confidence interval is given by:
Since the confidenc einterval not contains the value 0 we can conclude that we have significant difference between the two population proportion of interest 1% of significance given. So then we can't conclude that the two proportions are equal
Step-by-step explanation:
Let p1 and p2 the population proportions of interest and let and the estimators for the proportions we know that the confidence interval for the difference of proportions is given by this formula:
And for this case the confidence interval is given by:
Since the confidence interval not contains the value 0 we can conclude that we have significant difference between the two population proportion of interest 1% of significance given. So then we can't conclude that the two proportions are equal
We have to find the focus of the parabola with equation:
In order to find the focus, we first need to convert the equation of parabola to its standard form, as shown below:
Comparing this equation to the similar general equation of parabola, we get:
k = -3
p= 3/4
h = - 2
The focus of the general parabola is located at ( h+p, k)
Using the values, we get:
Focus of the given parabolic satellite =
Answer:
C. 6x² + 12xy
Step-by-step explanation:
Distribute the 3x to both terms in the parenthesis by multiplying them together...
3x(2x) + 3x(4y)
6x² + 12xy
