On his first day of school, Kareem found the high temperature in degrees Fahrenheit to be 76.1°. He plans to use the function C

of F = five-ninths (F minus 32) to convert this temperature from degrees Fahrenheit to degrees Celsius. What does C(76.1) represent? the temperature of 76.1 degrees Fahrenheit converted to degrees Celsius the temperature of 76.1 degrees Celsius converted to degrees Fahrenheit the amount of time it takes a temperature of 76.1 degrees Fahrenheit to be converted to 32 degrees Celsius the amount of time it takes a temperature of 76.1 degrees Celsiu

Answer:

(A)the temperature of 76.1 degrees Fahrenheit converted to degrees Celsius

Step-by-step explanation:

Kareem plans to use the function C(F) = \dfrac59(F-32) to convert temperature from degrees Fahrenheit to degrees Celsius.

The function gives a result in degrees Celsius. Therefore, 76.1 is in degree Fahrenheit and the result C(76.1) will be in degree Celsius.

Therefore, C(76.1) represents the temperature of 76.1 degrees Fahrenheit converted to degrees Celsius.

The correct option is A.

Maria will spin the arrow on the spinner 2 times. What is the probability that the arrow will stop on the same letter twice? 19
gavmur [86]
Suppose the spinner lands on <em>a</em>.  There's a 1/3 chance that it'll land on <em>a</em> the second time.
Suppose the spinner lands on <em>b</em>.  There's a 1/3 chance that it'll land on <em>b</em> the second time.
Suppose the spinner lands on <em>c</em>.  There's a 1/3 chance that it'll land on <em>c</em> the second time.

We've covered all possibilities for the first spin, and they're all equal, so their average is 1/3.

The probability that it'll land on the same letter twice is 33.3%.

A greengrocer sells melons at a profit of 37.5% on price he pays for it.What is the ratio of cost price to selling price
gavmur [86]
S-selling price
c-cost price
p-profit
p=37,5%
\frac{s-c}{s}*100%=37,5%  /:100%
\frac{s-c}{s}=0,375   /*s
s-c=0,375*s  /-s
0-c=-0,625*s /:(-s)
\frac{c}{s}=0,625

Answer:

The  value is  P(A) =  0.133617

Step-by-step explanation:

From the question we are told that

  The  mean is  \mu =  7.5

  The standard deviation is  \sigma  =  0.2

  The safest water level is  between  7.2 and  7.8

Generally the probability that the selected pool has a pH level that is not considered safe is mathematically represented as

       P(A) =  1 - P(7.2 \le X  \le 7.8 )

Here  

      P(7.2 < X  < 7.8 ) = P(\frac{ 7.2 - \mu }{\sigma } <  \frac{X - \mu }{ \sigma }

Generally \frac{X - \mu }{ \sigma } =  Z (The  \ standardized \  value  \  of  X )

So

 P(7.2 < X  < 7.8 ) = P(\frac{ 7.2 - 7.5 }{0.2 } < Z    

 P(7.2 < X  < 7.8 ) = P(-1.5 < Z  

=>  P(7.2 < X  < 7.8 ) = P(Z <  1.5) - P(  Z < - 1.5)

From the z-table the probability of  (Z <  -1.5) and   (  Z <1.5)  are

    P(Z <  1.5) =  0.93319

and  

    P(Z <  -1.5) =  0.066807

So

      P(7.2 < X  < 7.8 ) =0.93319 - 0.066807

       P(7.2 < X  < 7.8 ) =0.0866383

So

   P(A) =  1 - 0.0866383

=>  P(A) =  0.133617
