$Area=width*length\\\\
Area=480in^2\\
length=1\frac{1}{5}width\\\\
480=width*1\frac{1}{5}width\\\\
480=1.2width^2\ \ \ | divide\ by\ 1.2\\\\
width^2=400\ \ \ | make\ square\ root\\\\
width=20in\\\\
length=20*1.2=24\ in\\\\
Dimensions:\ 24inx20in$

The correct option is A

Step-by-step explanation:

From the question we are told that

The mean is $\mu = 0.8 \ pounds$

The standard deviation is $\sigma = 0.25 \ pounds$

Generally the the probability that a randomly selected zucchini will weigh between 0 55 pound and 13 pounds is mathematically represented as

$P(0.55 < X < 1.3) = P(\frac{0.55 - 0.8}{ 0.25} < \frac{X - \mu}{\sigma } < \frac{1.3 - 0.8}{0.25})$

=> P(0.55 < X < 1.3) = P( -1 < Z < 2 )

So looking the option of normal curves given in the question we see that it is option A that matches our interval

Zucchini weights are approximately normally distributed with mean 08 pound and standard deviation 0.
