The probability would be 1/52, since there are only 1 two of diamonds in all 52 cards.

Final answer. 1/52 or 1.92%

Answer:

13/52

Step-by-step explanation:

a standard 52-card deck has 13 diamond cards (1,2,3,4,5,6,7,8,9,10,J,Q,K)

P(diamond) = number of diamonds/number of cards in a deck = 13/52

Marjorie drops an object from a height of h meters, and it hits the ground with a velocity of v m/s, as given by the function v

Savatey [412]

Answer:

The object was dropped at a height of 338.1 meters.

Step-by-step explanation:

According to the statement, the function velocity ( $v$ ), in meters per second, in term of the initial height of the object ( $h$ ), in meters, is represented by:

$v = \sqrt{19.6\cdot h}$ (1)

This formula represents a particular case of a free fall analyzed by means of the Principle of Energy Conservation. If we know that $v = 81.4\,\frac{m}{s}$ , then the height of the object before being dropped is:

$h = \frac{v^{2}}{19.6}$

$h = 338.059\,m$

The object was dropped at a height of 338.1 meters.

Use the formula L= 10 log 10 R, where Is the loudness of a sound and R is the sound's relative intensity. to find out how much l

WINSTONCH [101]

Answer:

$X=24.1decibels$

Step-by-step explanation:

From the question we are told that:

Loudness function $L= 10 log_{10} R$

Sound of a person $S_p=80\ decibels\ or 10^8$

Number of persons talking $n=20 people$

Generally the Relative intensity for 20 people is mathematically given by

Relative intensity for $R_{20}=$ $20*10^8$

Relative intensity for $R_{20}=$ $20^8$

Generally the loudness for 20 people is mathematically given by

$L_{20}= 10 log_{10} R$

$L_{20}= 10 log_{10} 20^8$

$L_{20}= 10 (8 log_{10} 20)$

$L_{20}= 104.1 decibels$

Therefore increase in loudness X is given as

$X=104.1-80=-52.90$

$X=24.1decibels$

The drawing below (not to scale) shows a running track. The ends are semicircles. The distance between the two inner parallel st

aleksklad [387]

We are looking for the inner perimeter of the track. Since there are two semicircles, these mix to form one full circle so we can use the formula to find the circumference of the circle with a diameter of 60 m, which was given to us. With a diameter of 60m, the radius will be 30m. Now we can solve this problem.
C = 2πr
C = 2π(30)
C = 60π
The semicircle ends of the track are a distance of 60π m, and now we just need to add the lengths of the inner track which are 100 m each. So:
P = 60π + 100m + 100m
P = 200 + 60π
P = 388.5 m
