Zara has a rectangular garden. The length of her garden is 12 feet and the width is 7 feet. She extends the width

prisoha [69]

Given the perimeter and length of the garden, the width of the garden was extended by 4 feet

<h3>How to find width of the garden</h3>

Length of the garden = 12 feet
Width of the garden = 7 feet

Width extension =( 7 + w) feet

Perimeter = 46 feet

Perimeter = 2(length+ width)

46 = 2{12 + (7 + w)}

46 = 2(12 + 7 + w)

46 = 2(19 + w)

46 = 38 + 2w

46 - 38 = 2w

8 = 2w

w = 8/2

w = 4 feet

Answer:

[-5, 4) ∪ (4, ∞)

Step-by-step explanation:

Given functions:

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

$g(x)=\sqrt{x+5}$

Composite function:

$\begin{aligned}(f\:o\:g)(x)&=f[g(x)]\\ & =\dfrac{1}{\sqrt{x+5}-3} \end{aligned}$

Domain: input values (x-values)

For $(f\:o\:g)(x)$ to be defined:

$x+5\geq 0 \implies x\geq -5$

$\sqrt{x+5}\neq 3 \implies x\neq 4$

Therefore, $-5\leq x < 4$ and $x > 4$

⇒ [-5, 4) ∪ (4, ∞)

A factory produces fuses, which are packaged in boxes of 22. Four fuses are selected at random from each box for inspection. The

mojhsa [17]

The probability of finding one of the two defective fuses is:
$\frac{2C1\times20C3}{22C4}=0.3117$
The probability of finding 2 defective fuses is: $\frac{2C2\times20C2}{22C4}=0.026$
Therefore the probability of rejecting is 0.3117 + 0.026 = 0.3377.
