An experiment consists of choosing objects without regards to order. Determine the size of the sample space when you choose the

sdas [7]

Answer:

a

$n= 75, 582$

b

$n= 2300$

c

$n = 253$

Step-by-step explanation:

Generally the size of the sample sample space is mathematically represented as

$n = \left N } \atop {}} \right. C_r$

Where N is the total number of objects available and r is the number of objects to be selected

So for a, where N = 19 and r = 8

$n = \left 19 } \atop {}} \right. C_8 = \frac{19 !}{(19 - 8 )! 8!}$

$= \frac{19 *18 *17 *16 *15 *14 *13 *12 *11! }{11 ! \ 8!}$

$n= 75, 582$

For b Where N = 25 and r = 3

$n = \left 25 } \atop {}} \right. C_3 = \frac{25 !}{(19 - 3 )! 3!}$

$= \frac{25 *24 *23 *22 ! }{22 ! \ 3!}$

$n= 2300$

For c Where N = 23 and r = 2

$n = \left 23 } \atop {}} \right. C_2 = \frac{23 !}{(23 - 2 )! 2!}$

$= \frac{23 *22 *21! }{21 ! \ 3!}$

$n = 253$

The length of a rectangle is 20 meters and the width is 4 meters. What is the perimeter of the rectangle? Do not include units i

alina1380 [7]

Answer:

$\boxed {\boxed {\sf 48 \ meters }}$

Step-by-step explanation:

The perimeter is the sum of the side lengths.

A rectangle has 4 sides: 2 lengths and 2 widths, so the perimeter formula is

$p= 2l+2w$

The length is 20 meters and the width is 4 meters.

$p= 2(20 \ m )+ 2(4 \ m )$

Multiply.

$p= 40 \ m + 8 \ m$

Add.

$p= 48 m$

The perimeter of the rectangle is <u>48 meters. </u>

Suppose that y varies inversely with x. write an equation for the inverse variation.y = 2 when x = 3

erastova [34]

For inverse variation:
y = k/x
2 = k/3
k = 6

Therefore, required equation is y = 6/x

A pie company arranges its three-flavor cheesecake sampler into equal-sized slices as shown, where S represents strawberry, C re

Citrus2011 [14]

Answer:

$37.68$ square inches

Step-by-step explanation:

Given:

A pie company arranges its three-flavor cheesecake sampler into equal-sized slices: S represents strawberry, C represents chocolate, and P represents plain.

Diameter of the pie = 12 inches

To find: total area of the strawberry portion in the pie

Solution:

Diameter of the pie = 12 inches

Radius of the pie (r) = Diameter / 2 = $\frac{12}{2}=6$ inches

Area of the pie = $\pi r^2=3.14(6)^2=113.04$ square inches

Ratio of the strawberry portion in the pie = $\frac{2}{6}=\frac{1}{3}$

Therefore,

total area of the strawberry portion in the pie = $\frac{1}{3}(113.04)=37.68$ square inches
