castortr0y [4]

If you would like to know the purchase price of Wilma's game, you can calculate this using the following steps:

15% of $43.89 = 15% * 43.89 = 15/100 * 43.89 = $6.5835 = $6.58

$43.89 - $6.58 = $37.31

5% of $37.31 = 5% * 37.31 = 5/100 * 37.31 = $1.8655 = $1.87

$37.31 - $1.87 = $35.44

The correct result would be <span>$35.44.</span>

A particular fruit's weights are normally distributed, with a mean of 476 grams and a standard deviation of 36 grams. The heavie

4vir4ik [10]

Answer:

Step-by-step explanation:

Given that:

mean (μ) = 476 grams, standard deviation (σ) = 36 grams. P(z) = 19%

The z score shows by how many standard deviation the raw score is above or below the mean. It is given by the equation:

$z=\frac{x-\mu}{\sigma}$

Since the 19% weigh more, therefore 81% (100% - 19%) weigh less.

From the normal distribution table, the z score that corresponds to a probability of 81%(0.81) = 0.87

We substitute z = 0.88 in the z score equation to find the raw score. Therefore:

$z=\frac{x-\mu}{\sigma}\\0.87=\frac{x-476}{36}\\ x-476=31.32\\x=31.32+476\\x=507.32\\$

x ≅ 507 grams

Therefore 19% of fruits weigh more than 507 grams
