Answer: $18.19

Step-by-step explanation:

The tax is applied after the discount so first find the discounted price:

= Price * ( 1 - discount rate)

= 20 * ( 1 - 15%)

= $17

The sales tax of 7% can then be applied:

= Price * ( 1 + tax rate)

= 17 * ( 1 + 7%)

= $18.19

Arisa [49]

Answer:

68% of the sample can be expected to fall between 28 and 32 cm

Step-by-step explanation:

The Empirical Rule states that, for a normally distributed random variable:

68% of the measures are within 1 standard deviation of the mean.

95% of the measures are within 2 standard deviation of the mean.

99.7% of the measures are within 3 standard deviations of the mean.

In this problem, we have that:

Mean = 30

Standard deviation = 2

What proportion of the sample can be expected to fall between 28 and 32 cm

28 = 30-2

28 is one standard deviation below the mean

32 = 30 + 2

32 is one standard deviation above the mean

By the Empirical Rule, 68% of the sample can be expected to fall between 28 and 32 cm

Calculate the volume, in cubic centimeters, of a box which is 125 cm long, 37 cm wide, and 68 cm high. Report your answer with c
viva [34]

Answer:

Volume = 314500cm^3

Step-by-step explanation:

Given

Length = 125cm

Width = 37cm

Height = 68cm

Required

Determine the volume

Volume is calculated as:

Volume = Length * Width * Height

Substitute values for Length, Width and Height

Volume = 125cm * 37cm * 68cm

Volume = 314500cm^3

<em>Hence, the volume of the box is </em>314500cm^3<em></em>

2. Given: mZABD = rº and mZACB = yo
Ede4ka [16]

Step-by-step explanation:

the angle ABC = 180 - x, as ABD and ABC are complementary angles on top of the bottom line : all angles around a point on one side of a line are always adding up to 180 degrees.

but because we also know that the sum of all angles in a triangle is 180 degrees too, we can say

180 = ACB + ABC + CAB

180 = y + 180 - x + CAB

0 = y - x + CAB

x = y + CAB

x - y = CAB

therefore, the second answer option is correct.

The figure shows that the polygon:

  • Has 6 sides.
  • Divided into 4 triangles.
  • Total interior angle measure of 180°.
  • Total measure of the interior angles of this polygon is 720°.

<h3>What is the polygon about?</h3>

The polygon has sides of: AB, BC, CD, DE, EF, FA.

So, this means that they have 6 sides and when you look at the diagram, this 6 sides can be divided into 4 triangle of which whose total interior will sum up to 180°.

Since there are 4 triangles and the interior is 180°, then to get  the total measure of the interior angles of this polygon will be:

= 180 X 4 = 720

Therefore, one can say that the The figure shows that the polygon, has 6 sides, may be divided into 4 triangles, each of which will have a total interior angle measure of  180. Therefore, the total measure of the interior angles of this polygon is 720.
