Answer:
meter is difference in height between the submarine and the aircraft
Step-by-step explanation:
The height of aircraft above the surface
meter
Depth at which the submarine lies below the surface
meter
Depth at which the underwater robotic vehicle below the surface
meter
Difference in height between the submarine and aircraft is equal to
meter
Answer:
A
Step-by-step explanation:
Given 2 secants from a point outside the circle.
Then the product of the external part and the entire secant of one secant is equal to the product of the external part and the entire secant of the other secant, that is
(x + 1)(x + 1 + 11) = (x + 4)(x + 4 + 1)
(x + 1)(x + 12) = (x + 4)(x + 5) ← expand both sides
x² + 13x + 12 = x² + 9x + 20 ← subtract x² + 9x from both sides
4x + 12 = 20 ( subtract 12 from both sides )
4x = 8 ( divide both sides by 4 )
x = 2 → A
The answer to the equation is 30%
A particular country has 60 total states. if the areas of all 60 states are added and the sum is divided by 60, the result is 212 comma 469 square kilometers. determine whether this result is a statistic or a parameter.
Answer: Before solving the given question, let us understand what the parameter and statistic is:
Parameter: Parameter is a number that summarizes data for an entire population. Like Population mean
Population standard deviation 
Statistic: Statistic is a number that summarizes data for a sample. Like sample mean
sample standard deviation
.
From the given information, we can clearly see that given characteristic describes the population.
Therefore, the option d is correct
d. the result is a parameter because it describes some characteristic of a population. is correct.
