Yunika downloaded three applications for $2.99 each to her cell phone. The remaining applications that Yunika purchased cost $1.

777dan777 [17]

You can formulate the equation below to work out your question:

3(2.99) + 1.99(x-3)
8.97 + 1.99x - 5.97
1.99x + 3

CHECK:
If x = 5
3 x 2.99 + 2 x 1.99 = 8.97 + 3.98 = 12.95
1.99 x 5 +3 = 12.95

Hope I helped.

A paint machine dispenses dye into paint cans to create different shades of paint. The amount of dye dispensed into a can is kno

Anton [14]

Answer:

4.464 ml

Step-by-step explanation:

Given that:

mean (μ) = 5 mm, standard deviation (σ) = 0.4 ml

The z score is a score in statistics used to determine by how many standard deviation the raw score is above or below the mean. If the z score is positive then the raw score is above the mean and if the z score is negative then the raw score is below the mean It is given by:

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

From the normal distribution table, the 9th percentile (0.09) corresponds to a z score of -1.34

$z=\frac{x-\mu}{\sigma}\\\\-1.34=\frac{x-5}{0.4}\\\\x-5=-0.536\\\\x=5-0.536\\\\x=4.464$

The dye amount that represents the 9th percentile of the distribution is 4.464 ml
