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

Ket [755]

Answer:

0.9115 is the proportion of paint cans that contain less than 5.54 ml of the dye.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 5 ml

Standard Deviation, σ = 0.4 ml

We are given that the distribution of amount of dye dispensed is a bell shaped distribution that is a normal distribution.

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

P(paint cans contain less than 5.54 ml of the dye)

$P( x < 5.54) = P( z < \displaystyle\frac{5.54 - 5}{0.4}) = P(z < 1.35)$

Calculation the value from standard normal z table, we have,

$P(x < 5.54) =0.9115 = 91.15\%$

0.9115 is the proportion of paint cans that contain less than 5.54 ml of the dye.

Joanna buys a table and 2 chairs. She receives a 25% discount for being a preferred customer and then pays 6% sales tax on the d

Scrat [10]

The total purchase price is $ 357.75

Solution:

Joanna buys a table and 2 chairs

Cost of table = $ 250

Cost of 1 chair = $ 100

Therefore, cost of a table and 2 chairs = 250 + 2(100) = 450

Thus, cost price = $ 450

She receives a 25% discount for being a preferred customer

Therefore, discount = 25 % of cost price

$discount = 25 \% \times 450\\\\discount = \frac{25}{100} \times 450\\\\discount = 0.25 \times 450 = 112.5$

Thus, amount after discount = cost price - discount

amount after discount = 450 - 112.5 = 337.5

Thus, amount after discount is $ 337.5

Then pays 6% sales tax on the discounted purchase price

Sales tax = 6 % of 337.5

$sales\ tax = 6 \% \times 337.5\\\\sales\ tax = \frac{6}{100} \times 337.5\\\\sales\ tax = 20.25$

Thus, total purchase price is given as:

total purchase price = Amount after discount + sales tax

total purchase price = 337.5 + 20.25 = 357.75

Thus total purchase price is $ 357.75

$\angle BAD=100^{\circ}$ (opposite angles in a parallelogram)

$\angle EAD=80^{\circ}$ (subtraction)

$\angle ADE=65^{\circ}$ (angles in a triangle add to 180 degrees)

$\angle CDA=80^{\circ}$ (adjacent angles in a parallelogram are supplementary)

$\boxed{\angle CDE=15^{\circ}}$ (subtraction)

$\angle CED=65^{\circ}$ (angles in a triangle add to 180 degrees)

$\boxed{\angle AEB=80^{\circ}}$ (angles on a straight line add to 180 degrees)
