One can convert temperature from Kelvin into Fahrenheit using the formula F=95(K−273)+32. What is the temperature in Kelvin corr

DiKsa [7]

Answer:

The temperature in Kelvin corresponding to F degrees Fahrenheit is $K=\frac{F-32}{95}+273$

Step-by-step explanation:

Given : One can convert temperature from Kelvin into Fahrenheit using the formula $F=95(K-273)+32$ .

To find : What is the temperature in Kelvin corresponding to F degrees Fahrenheit?

Solution :

Temperature from Kelvin into Fahrenheit is given by,

$F=95(K-273)+32$

Writing Kelvin in terms of Fahrenheit,

Subtract 32 both side,

$F-32=95(K-273)$

Divide by 95 both side,

$\frac{F-32}{95}=K-273$

Add 273 both side,

$\frac{F-32}{95}+273=K$

Therefore, The temperature in Kelvin corresponding to F degrees Fahrenheit is $K=\frac{F-32}{95}+273$

Aneli [31]

The probability that Pete exceeds 200 in at least 9 of his next 10 games is 0.268+0.1074 = 0.3754

<h3>What is Probability ?</h3>

Probability is defined as the likeliness of an event to happen.

It has a range of 0 to 1.

It is given that

Pete, a professional bowler, is unhappy with any game below 200

80% of his games exceed this score.

the probability that Pete exceeds 200 in at least 9 of his next 10 games is given by

P( 9/10 > 200) +P(10/10>200)

The binomial experiment consists of n trial out of it x is success.

$P( x) = \dfrac{n!}{x!(n-x)!}p^x(1-p)^{n-x}$

Here p = 0.8

For 9/10 matches

$P( 9/10 > 200) = \dfrac{10!}{9!(10-9)!}0.8^9(1-0.8)^{10-9}\\\\ = {10}(0.8)^9(0.2)\\= 0.268$

For (10/10 >200)

$P( 10/10 > 200) = \dfrac{10!}{10!(10-10)!}0.8^{10} (1-0.8)^{10-10}\\\\ = {1!}(0.8)^{10}\\= 0.1074$

Therefore the probability that Pete exceeds 200 in at least 9 of his next 10 games is 0.268+0.1074 = 0.3754.
