1. A gambler makes 100 column bets at roulette. The chance of winning on any one play is 12/38. The gambler can either win $ 5 o

lapo4ka [179]

Answer:

a) Expected amount of the gambler's win = $0.209

b) SD = 2.26

c)P (X >1) = P(z >0.35) = 0.36317

Step-by-step explanation:

The probability of winning, p = 12/38 =6/19

Probability of losing, q = 1 -p = 1-6/19

q = 13/19

Win amount = $5

Loss amount = $2

a) Expected total amount of win = ((6/19)*5) - ((13/19)*2)

Expected total amount of win = 1.579 - 1.369

Expected amount of win, E(X) = $0.209

b) Standard Deviation for the total amount of the gambler's win

$SD = \sqrt{E(X^{2}) - (E(X))^{2} }$

E(X²) = (6/19)*5² - (13/19)*2²

E(X²) = 5.158

$SD = \sqrt{5.158 - 0.209^2}$

SD = 2.26

c) probability that, in total, the gambler wins at least $1.

P(X >1)

$z = \frac{X - \mu}{\sigma}$

μ = E(x) = 0.209

z = (1-0.209)/2.26

z = 0.35

P( X >1) = P(z >0.35)

P(z >0.35) = 1 - P(z <0.35)

P(z >0.35) = 1 - 0.63683

P(z >0.35) = 0.36317

Help need awnser ASAP

zzz [600]

Answer:

(B)

Step-by-step explanation:

It is given that: From ΔONP and ΔMLP,

$\frac{PO}{PL}=\frac{PN}{PM}$ (By basic proportionality theorem)

∠MPL=LPM(Common)

Therefore, ΔONP is similar to ΔMLP by SAS similarity postulate.

Also, From ΔONP and ΔKPJ,

$\frac{PO}{PK}=\frac{PN}{PJ}$ (By basic proportionality theorem)

∠OPN=KPJ(Common)

therefore, ΔONP is similar to ΔKPJ by SAS similarity postulate.

Now, since ΔONP is similar to ΔMLP by SAS similarity postulate and ΔONP is similar to ΔPJK by SAS similarity postulate, therefore ΔMLP is similar to ΔPJK by SAS similarity postulate.

Thus, all the three center triangles are similar by SSS similarity postulate.

V = lwh/3 (solve for h)

victus00 [196]

Answer:

$\displaystyle V = \frac{lwh}{3} \rightarrow h = \frac{3V}{lw}$

General Formulas and Concepts:

Pre-Algebra

Equality Properties

Multiplication Property of Equality
Division Property of Equality
Addition Property of Equality
Subtraction Property of Equality

Algebra I

Terms/Coefficients

Step-by-step explanation:

Step 1: Define

Identify

$\displaystyle V = \frac{lwh}{3}$

Step 2: Solve for h

[Multiplication Property of Equality] Multiply 3 on both sides: $\displaystyle V = \frac{lwh}{3} \rightarro 3V = lwh$
[Division Property of Equality] Divide lw on both sides: $\displaystyle V = \frac{lwh}{3} \rightarrow h = \frac{3V}{lw}$

A circular table has a radius 56cm. A tablecloth covers the table. The edge of the cloth is 10cm below the tabletop. What is the

REY [17]

Answer:

13,363.84 square cm

Step-by-step explanation:

For this question,

The circle table has a radius of 56 cm and the height of the edge of the cloth is 10cm(height) below the tabletop, which is a rectangle

We need to find out the area of a circle, Then the area of the rectangle.

Area of circle FORMULA= πr^2 | Area of rectangle FORMULA = l * h

πr^2

3.14 * 56 * 56 = area of circle = 9,847.04

[(2*3.14*56)Perimeter of circle which is also length of rectangle] * 10 = area of rectangle = 3516.8

9,847.04 + 3516.8 = 13,363.84
