Answer:1/(8a^12)

Step-by-step explanation:

(2a^4)^-3

2^(-3) x (a^4)^(-3)

1/(2^3) x a^(-12)

1/(2x2x2) x 1/(a^12)

1/8 x 1/a^12

1/(8a^12)

aivan3 [116]

1st quartile (25%) and the 3rd quartile (75%) values are -0.6745 and 0.6745 respectively. Use this formula z= (x-mean)SD -0.6745 = (x-25.3)/6.5.
x=25.3 - 0.6745(6.5) = 25.3 - 4.3843 = 20.9157 1st Quartile
0.6745 = (x - 25.3) 6.5
x = 25.3 + 0.6745 = 25.3 + 4.3843 = 29.6843 3rd quartile
interquartile range is the difference between the 1st quartile and the 4th quartile

Please help me solve this with multiplication. Thankl you!

Answer:

1/6x² -1/6x -1/8

Step-by-step explanation:

The distributive property applies. Fractions are multiplied and added in the usual way.

<h3>Product of binomials</h3>

The distributive property is used to eliminate parentheses. It can be convenient to write the fractions with a common denominator, then simplify the final product.

$\left(\dfrac{1}{2}x+\dfrac{1}{4}\right)\left(\dfrac{1}{3}x-\dfrac{1}{2}\right)=\dfrac{2x+1}{4}\cdot\dfrac{2x-3}{6}=\dfrac{1}{24}((2x)(2x-3)+1(2x-3))\\\\=\dfrac{1}{24}(4x^2-6x+2x-3)=\boxed{\dfrac{1}{6}x^2-\dfrac{1}{6}x-\dfrac{1}{8}}$
