A pharmaceutical company interviews 12 people for eight openings in the research department of the company. 7 of the 12 people a
viva [34]

Answer:

(a) 495, (b) 210

Step-by-step explanation:

Total number of persons = 12

number of openings = 8

number of women = 7

number of men = 12 - 7 = 5

(a) Number of ways to select the 8 persons

C_{8}^{12}\textrm{}\\\\= \frac{12!}{8!\times 4!}\\\\=495

(b) Three are men

So, 3 men and 5 women

The number of ways are

C_{3}^{5}\textrm{} \times C_{5}^{7}\textrm{}\\\\= \frac{5!}{3!\times 2!}\times \frac{7!}{5!\times 2!}\\\\=210

A square garden has a diagonal of 34 ft. Colton wants to put a fence around the entire garden.
andreyandreev [35.5K]
Let x be the side of your square. Use Pythagoras to find the side in the right triangle formed with 2 sides and the diagonals:

x² + x² = 34²

2x² = 34² = 1126

x² = 1126/2 = 578
and x =√578 = 17√2 ≈ 24 ft
H will need 24 x 4 = 96 ft

Find the surface area of the rectangular prism
grin007 [14]

Answer:

23 units²

Step-by-step explanation:

height = 2

length = 4

width = 2.5

Formula = 2(wl + lh + hw) ⇒ 2 [(2.5 × 4) + (4 × 2) + (2 ×2.5)] = 23 units²

Hope this helps.

Solve for the measure of angle 7
Verdich [7]

Answer:

7 is 35°

Step-by-step explanation:

The measure of an exterior angle is equal to the sum of opposite interior angles.

So 4x - 80 = x + x - 10

4x - 2x = 80 - 10

2x = 70 , x = 35°

Hence 7 is 35°

A sphere is inscribed in a cube with a surface area of 216 square centimeters. What is the volume of the sphere
pentagon [3]

Answer:

V=298.5cm^3

Step-by-step explanation:

To find the volume of the sphere we need to know its radius.

And the radius can be found with the information we have about the surface area.

The formula for the surface area is as follows:

SA=4\pi r^2

from this formula we clear the radius r:

r^2=\frac{SA}{4\pi}\\ \\r=\sqrt{\frac{SA}{4\pi} }

and we substitute the known value of the surface area, and also the value of \pi:

r=\sqrt{\frac{216cm^2}{4(3.1416)} }\\ \\r=\sqrt{\frac{216cm^2}{12.5664} }\\ \\r=\sqrt{17.1887cm^2}\\ \\r=4.146cm

and now that we know the radius we find the volume:

V=\frac{4\pi r^3}{3} \\\\V=\frac{4(3.1416)(4.146cm)^3}{3}\\ \\V=\frac{895.521cm^3}{3}\\ \\V=298.5cm^3

the volume of the sphere is 298.5cm^3
