Answer:

$\frac{7}{11}$

Step-by-step explanation:

Probability is defined as the likelihood of an event occurring.

-The probability of being selected is :

$P_s=\frac{4}{11}$

-The probability of not being selected is :

$P_{ns}=1-P_s\\\\=1-\frac{4}{11}\\\\=\frac{7}{11}$

Hence, the probability of John not being selected is $\frac{7}{11}$

Kaitlyn and Hakim each bought a tube

Pie

<h2>Answer:</h2>

<h3>container B requires more plastic to make.</h3>

<h2>Step-by-step explanation:</h2>

Container A:

diameter- 7 cm

height- 122 cm

radius- 3.5 cm

<h3>calculating for the surface area</h3>

SA=2×π×r×r+2×π×r×h

SA=2(3.14)(3.5)(3.5)+2(3.14)(3.5)(122)

SA=76.93+2681.56

SA=2758.49 cm^2

<h3>Container B:</h3>

diameter- 11 cm

height- 85 cm

radius- 5.5 cm

<h3>calculating for the surface area</h3>

SA=2×π×r×r+2×π×r×h

SA=2(3.14)(5.5)(5.5)+2(3.14)(5.5)(85)

SA=189.97+2935.90

SA=3125.87 cm^2

<h3>Container B required more plastic to make</h3>

The owner of the Outdoor Furniture Center decides to use the 120% markup. At the end on

lana66690 [7]

Answer: The total price of a bench is 1.008x.

Step-by-step explanation:

Since we have given that

Let the cost price be 'x'.

Mark up % = 120%

So, Mark up value would be

$\dfrac{120}{100}x\\\\=1.20x$

Discount % = 20%

Amount of discount is given by

$\dfrac{20}{100}\times 1.2x\\\\=0.2\times 1.2x\\\\=0.24x$

So, it becomes,

Amount after discount is given by

$1.2x-0.24x\\\\=0.96x$

Sales tax = 5%

Amount of sales tax would be

$\dfrac{100+5}{100}\times 0.96x\\\\=\dfrac{105}{100}\times 0.96x\\\\=1.05\times 0.96x\\\\=1.008x$

Hence, the total price of a bench is 1.008x.
