A fair coin is tossed 20 times. The probability of getting the three or more heads in a row is 0.7870 and the probability of get

adelina 88 [10]

Answer:

The value is $P( H \ n \ T ) = 0.6049$

Step-by-step explanation:

From the question we are told that

The number of times is n = 20

The probability of getting three or more heads in a row is $P(H) = 0.7870$

The probability of getting three or more heads in a row or three or more tails in a row is $P(H \ u \ T ) = 0.9791$

Generally given that it is a fair coin , then $P(H) = P(T) = 0.7870$

Here P(T) is probability of getting three or more tails in a row

Generally the probability of getting three or more heads in a row and three or more tails in a row is mathematically represented as

$P( H \ n \ T ) = P(H) + P(T) - P( H \ u \ T )$

=> $P( H \ n \ T ) = 0.7870 + 0.7870 - 0.9791$

=> $P( H \ n \ T ) = 0.6049$

Find the mass of the object if it has a volume of 20 mL and a density of 3 g/mL.

photoshop1234 [79]

Answer:

60 g

Step-by-step explanation:

Use the density formula, D = m/v, where m is the mass and v is volume

Plug in the volume and density, then solve for the mass:

D = m/v

3 = m/20

60 = m

So, the mass is 60 g

-3(x-2)=12 solve the equation

jonny [76]

Answer:

Step-by-step explanation:

-3(x-2)=12

-3x+6-6=12-6

-3x=6

divide by -3

-3x/3=6/-3

x=-2
