Answer:

$\sf\longmapsto \: x = 10$

Step-by-step explanation:

$\sf\longmapsto \: 2x = 22 - 2$

$\sf\longmapsto \: 2x = 20$

$\sf\longmapsto \: x = \frac{20}{2}$

$\sf\longmapsto \: x = 10$

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

The vertex of this parabola is at (2, -4). When the y-value is -3, the x-value is -3. What is the coefficient of the squared ter

lyudmila [28]

Answer:

The squared term is 1/25

Step-by-step explanation:

The parabola equation in the vertex form is

$y = a \times (x - h)^2 + k$

where point (h,k) is the vertex and a is the squared term. In this case h = 2 and k = -4. On the other hand, we know that y = -3 and x = -3 are in the parabola. Replacing these values in the formula gives

$-3 = a \times (-3 - 2)^2 - 4$
