Sindrei [870]

Answer:

143.70 = 3(39.95) + x

where x is the additional fee spent to race the cars at the park

Step-by-step explanation:

Let’s write the complete question first before we solve;

Blake and two of her friends are going to an amusement park. The cost of admission to the park is $39.95 per person. Once they are in the park, Blake and her friends ride the race cars, which require an additional fee. The total amount spent by all three boys is $143.70. Write an equation that can be used to find the additional fee to ride the race cars.

solution;

we are trying to write an equation that could help determine the additional fee used to race cars at an amusement park by a group of friends.

we proceed as follows;

We identify that they are 3, with each spending an amount equal to $39.95 for admission.

now to find the additional fee, we simply multiply the admission fee by 3 and subtract from the total amount spent.

let’s say the additional fee is x

This means;

143.70 = 3(39.95) + x

To get x, we can then open the bracket then take the value to the other side to get x

Scores on a college entrance examination are normally distributed with a mean of 500 and a standard deviation of 100. What perce
Alla [95]

Answer:

The percentage is P(350 <  X  650 ) = 86.6\%

Step-by-step explanation:

From the question we are told that

   The population mean is  \mu  =  500

     The standard deviation is  \sigma  =  100

The  percent of people who write this exam obtain scores between 350 and 650    

    P(350 <  X  650 ) =  P(\frac{ 350 -  500}{ 100}

Generally  

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

   P(350 <  X  650 ) =  P(\frac{ 350 -  500}{ 100}

   P(350 <  X  650 ) =  P(-1.5

   P(350 <  X  650 ) =  P(Z < 1.5) -  P(Z <  -1.5)

From the z-table  P(Z <  -1.5 )  =  0.066807

   and P(Z < 1.5  ) =  0.93319

=>    P(350 <  X  650 ) =  0.93319 -  0.066807

=>  P(350 <  X  650 ) = 0.866

Therefore the percentage is  P(350 <  X  650 ) = 86.6\%
