Answer:
The probability a random selected radish bunch weighs between 5 and 6.5 ounces is 0.8185
Step-by-step explanation:
The weight of the radish bunches is normally distributed with a mean of 6 ounces and a standard deviation of 0.5 ounces
Mean =
Standard deviation =
We are supposed to find the probability a random selected radish bunch weighs between 5 and 6.5 ounces i.e.P(5<x<6.5)
At x = 5
Z=-2
At x = 6.5
Z=1
Refer the z table for p value
P(5<x<6.5)=P(x<6.5)-P(x<5)=P(Z<1)-P(Z<-2)=0.8413-0.0228=0.8185
Hence the probability a random selected radish bunch weighs between 5 and 6.5 ounces is 0.8185
Using proportions, it is found that $1,225 is earned from nachos.
- This question is solved by <em>proportions</em>, using a rule of three.
- The measures have an inverse relationship, hence line multiplication is applied instead of cross multiplication.
- When the theater makes $1,540 from popcorn sales, it makes $1,330 from nacho sales. How much is earned from nachos when $1,672 is earned from popcorn?
The <em>rule of three</em> is:
$1,540 - $1,330
$1,672 - $x
Applying line multiplication:
$1,225 is earned from nachos.

Equivalent form of the first equation that eliminates x when added to the second
To do this, we simply make the coefficients of x to be opposite in both equations.
In the second equation, the coefficient of x is 8.
So, we need to make the coefficient of x -8, in the first equation.
Multiply by -10
<em>When this is added to the first equation, the x terms becomes eliminated</em>
