Answer:
<em>D</em>
Step-by-step explanation:
I tried all the other equations by plugging in numbers and disproving their accuracy. <u>D was the only one that worked.</u>
Area of a triangle=bh/2
27= x(x-3)/2
27= (x^2-3x)/2
54= x^2-3x
x^2-3x-54=0
(x-9)(x+6)=0
x=9, x=-6.
In this case, x must equal 9 since the base cannot be a negative number.
Final answer: Height=6 m

Step-by-step explanation:
Considering the median, the missing value of the data-set is of 31.
<h3>What is the median of a data-set?</h3>
The median of the data-set separates the bottom half from the upper half, that is, it is the 50th percentile.
In this problem, since the set has even cardinality, the median is the mean of the middle elements, which are 23 and x. Since it is of 27, we have that:
(23 + x)/2 = 27
23 + x = 54
x = 31
Hence, the missing value of the data-set is of 31.

Answer:
Dilacey took a loan of $2800
Step-by-step explanation:
P=(Simple Interest×100)/R×T
P=$420×100/10×1½
