Answer:
Step-by-step explanation:
All the interior angles are of measure 60 degrees.
We want to find the height of this triangle. Call it h. On the left side of this illustration is a right triangle with height h and base (1/2)(10), or 5.
The ratio of height to base is the tangent of 60 degrees:
h
tan 60 degrees = --------------
5
h
and tan 60 degrees = 1.73 = ------
5
Multiplying both sides of this equation by 5 yields h = 8.66. This is |BD|. This is the same as Answer B.

Q) WHICH FORMULA SHOULD BE USED TO CALCULATE VARIANCE?
ANSWER)
We know that there are 2 types of variance, Population variance and sample variance. As in this question, we are considering all the values of the data to find variance. we'll find Population Variance. If we would considered only some values (sample) from the data (population), we would have considered to find sample variance.
Population Variance is given as sigma squared which is calculated by sum of square variables minus mean, divided by number of observation in population.
which is represented by option C
Answer:
(x+6)[ 3x-5]
Step-by-step explanation:
3x(x + 6) - 5(6 + x)
We can rewrite the second term in parentheses because order doesn't matter in addition inside the parentheses
3x(x + 6) - 5( x+6)
Factor out the (x+6)
(x+6)[ 3x-5]
Answer:
The volume of paint that covers the whole car is gallons or one and a quarter gallons.
Step-by-step explanation:
Let the volume of paint required to cover whole car be 'x'.
Given:
Volume of paint to cover one-fifth of a car = one-fourth of a gallon.
We use unitary method to determine the volume of paint required.
∵ One-fifth of a car requires paint =
∴ Whole volume of car requires paint =
Therefore, the volume of paint that covers the whole car is gallons or one and a quarter gallons.
