<h2><u>106 square inches</u> is the correct answer!</h2><h3></h3><h3>1. Divide the shape into three sections (Two rectangles and one triangle)</h3><h3></h3><h3>2. Calculate the area of the triangle:</h3><h3>One side is 4 inches and the other side is 5 + 3 + (7 - 4) = 11 inches.</h3><h3>4 x 11 = 44</h3><h3>44 ÷ 2 = <u>22</u></h3><h3></h3><h3>3. Calculate the area of the top rectangle:</h3><h3>One side is 8 inches and the other side is 3 inches.</h3><h3>8 x 3 = <u>24</u></h3><h3></h3><h3>4. Calculate the area of the lower rectangle:</h3><h3>One side is 6 inches and the other side is 7 + 3 = 10 inches.</h3><h3>6 x 10 = <u>60</u></h3><h3></h3><h3>5. Add all of them together</h3><h3>22 + 24 + 60 = <u>106</u></h3><h3></h3><h3><em>Please let me know if I am wrong.</em></h3>

kow [346]

Answer: 0.6

Step-by-step explanation:

The probability formula to find p(B/A) is :

P(B/A) = p(A n B) / p(B)

Which means that A is contain in B and p(A n B) is p(A)

p(A n B)= p(A)=0.6 × 0.05 = 0.03

p(B)=0.05

Therefore

P(B/A) = p(A n B) / p(B)=p(A) / p(B)

P(B/A)=0.03 / 0.05

P(B/A)=0.6

Answer:

$\dfrac{z-y}{a+b}$

Step-by-step explanation:

Given expression:

$\dfrac{z^2-y^2}{a^2-b^2}\div \dfrac{z+y}{a-b}$

Substitute

$a^2-b^2=(a-b)(a+b)\\ \\z^2-y^2=(z-y)(z+y)$

into the expression:

$\dfrac{(z-y)(z+y)}{(a-b)(a+b)}\div \dfrac{z+y}{a-b}\\ \\ \\=\dfrac{(z-y)(z+y)}{(a-b)(a+b)}\times \dfrac{a-b}{z+y}\\ \\ \\=\dfrac{z-y}{a+b}$

Define a function f on a set of real numbers as follows: f(x) = 3x − 1 x , for each real number x ≠ 0 Prove that f is one-to-one

dalvyx [7]

Answer with Step-by-step explanation:

We are given that

$f(x)=\frac{3x-1}{x}$

For each real number $x\neq 0$

To prove that f is one -to-one.

Proof:Let $x_1$ and $x_2$ be any nonzero real numbers such that

$f(x_1)=f(x_2)$

By using the definition of f to rewrite the left hand side of this equation

$f(x_1)=\frac{3x_1-1}{x_1}$

Then, by using the definition of f to rewrite the right hand side of this equation of $f(x_1)=f(x_2)$

$f(x_2)=\frac{3x_2-1}{x_2}$

Equating the expression then we get

$\frac{3x_1-1}{x_1}=\frac{3x_2-1}{x_2}$

$3x_1x_2-x_2=3x_2x_1-x_1$

$3x_1x_2-3x_1x_2+x_1=x_2$

$x_1=x_2$

Therefore, f is one-to-one.
