Class A has a Greater number of lower quartiles then Class B as the imagie shows. Class A has 65-75 while class B has 70-75.
Answer:
45 °
Step-by-step explanation:
m< ABC = m< DBC + m< ABD
= 115 _ 70
= 45 °
<h2>9x^4 - 6x^2 - 3x - 6</h2><h2 />
(9x^4-13x^3-x-7)+(7x^3-2x+1)
Sort the terms by their powers, as x's with the same powers can be added together:
9x^4
-13x^3 + 7x^3 = -6x^3
-x - 2x = -3x
-7 +1 = -6
<h2>9x^4 - 6x^2 - 3x - 6</h2>
IN the given figure.
angle A + angle B + angle C = 180°
( angle sum property of Δ)
58°+47°+ x = 180°
105°+ x =180°
x = 180° - 105°
<h3>x = 75°</h3>
thus correct option is (d)
hope this will help u!!
