45th percentile means that 45% of the data fall below that number while 55% (that is, 100-45) fall above it.
Now, arranging the number in ascending order;
$60, $85, $95, $105, $120, $145, $155, $175, $190, $215, $235, $240, $260, $285, $325
The total number of counts = 15
Then,
Index = 15*45% = 15*0.45 = 6.75
Round up,
Index = 7
The,
7th number = $155
Therefore, 45th percentile value of the data = $155
Answer:
x = 69
Step-by-step explanation:
The exterior angle is equal to the sum of the opposite interior angles in a triangle
x+90 = 159
Subtract 90 from each side
x +90-90 = 159-90
x =69
Das is difference of 2 perfect squares
remember
a^2-b^2=(a-b)(a+b)
so
25x^4=(5x^2)^2
16y^2=(4y^2)
(5x^2)^2-(4y)^2=(5x^2-4y)(5x+4y)
cannot be factored further
Answer:
192
Step-by-step explanation:
The volume of a prism is 3 cubic units. Dividing each cube into 1/4 size cubes means each small cube will have 1/64 cubic inches.
This means 64 1/4 cubes fit into 1 cube. So for 3 cubes, 3*64 = 192 cubes.
