Answer:
39°
Step-by-step explanation:
A radius of a circle (segment CD) drawn to the point of tangency (D) intersects the tangent (line DE) at a 90-deg angle.
That makes m<D = 90.
m<D + m<C + m<E = 180
90 + 51 + m<E = 180
m<E = 39
Answer:
A. The first equation is for sample data; the second equation is for a population.
Step-by-step explanation:
The first equation is y =
, this is the equation for sample data as the intercept (
) and the slope parameter(
) both are calculated then we have got this and these values are not taken as given.
The Second equation is
, this is the equation for population data as we can't calculate these
and
as we take these values as given and also we do testing for
parameter using t test and it is sure that testing is always done on population data not on sample data.
X= is the number looked for.
56% of x=14
We suggest this equation:
(56/100)x=14
x=(14*100)/56=25
Solution: 25
The radius of the cone is 8.9 ft
