In a gambling game a person draws a single card from an ordinary 52-card playing deck. A person is paid $17 for drawing a jack o
Artyom0805 [142]

Answer:

E.G=\$2

Step-by-step explanation:

Sample size 52 card

Pay for J or Q =\$17

Pay for King or Ace =\$5

Pay for others =-\$2

Therefore

Probability of drawing J or Q

P(J&Q)=\frac{8}{52}

Probability or drawing King or Ace

P(K or A)=\frac{8}{52}

Probability or drawing Other cards

P(O)=\frac{36}{52}

Therefore

Expected Gain is mathematically given as

E.G=\sum_xP(x)

E.G=17*\frac{8}{52}+5*\frac{8}{52}+(-2)*\frac{36}{52}

E.G=\$2

I need to graduate please.<br>Which expression is a perfect cube?<br> x^8<br> y^24<br> m^26<br> s^64
myrzilka [38]
Remember
(a^b)^c=a^{bc}

note that if a^3 is a perfect cube then (a^3)^c is also a perfect cube when c is an integer

(a^3)^c=a^{3c}
so if a number is a perfect cube then the power must be divisible by 3

8 is not divisible by 3
24 is divisible by 3
26 is not divisibley by 3
64 is not divisible by 3

the perfect cube is y^24

What does a star mean after a number
Triss [41]
A star is written to show multiplication. It is a replacement for a dot or a x which is what you probably learned to be the "times" sign. In upper level maths, the "x" is replaced with a " * " to make it more legible and to avoid confusion with the variable "x".

The weight Wkg of a metal bar varies jointly
maria [59]

Answer:

d = \sqrt{\frac{216W}{35L} }

Step-by-step explanation:

Given that W varies jointly as L and d² then the equation relating them is

W = kLd² ← k is the constant of variation

To find k use the condition W = 140 when d = 4 and L = 54, thus

140 = k × 54 × 4² = 864k ( divide both sides by 864 )

\frac{140}{864} = k , that is

k = \frac{35}{216}

W = \frac{35}{216} Ld² ← equation of variation

Multiply both sides by 216

216W = 35Ld² ( divide both sides by 35L )

\frac{216W}{35L} = d² ( take the square root of both sides )

d = \sqrt{\frac{216W}{35L} }
