Answer:

$25.44

Step-by-step explanation:

First, you multiply, 5*8 = $40.00

Then you subtract the discout, 40-40% = $24.00

Lastly, you must add the sales tax, 24+6% = $25.44

The total cost of the binders is $25.44

Given the five number summary, christina has scored 70 marks which is equal to the median of the test scores, therefore about [tex]\frac{1}{2}[/tex] class scored higher than her and  [tex]\frac{1}{2}[/tex] class scored lower than her, making option (d) correct.

The five number summary is the descriptive summary of a data where in you are provided the lowest observation, first quartile, median, third quartile and the maximum observation.

Here, the first quartile is the observation which lies at a point in the ordered data that 25% observations are lesser than it and 75% are greater than it.

the median is the observation which lies at a point in the ordered data that 50% observations are lesser than it and 50% are greater than it.

the third quartile is the observation which lies at a point in the ordered data that 75% observations are lesser than it and 25% are greater than it.

As given in the data,

Christina's marks = 70

median marks = 70

christina's marks = median marks

therefore, by definition of median, about half class scored lower than christina and half more than her.

Answer:

If you want to turn a percentage into a fraction divide by 100:

20%/100 = 0.2

0.2*16 = 3.2$

Percentage is the part of a whole given as a fraction of the hundred. The discounted price of the CD is $12.8.

Andrew has a coupon for 20 % off of the price of any CD.

The price of the CD purchased by the Andrew is $16.

Percentage is the part of a whole given as a fraction of the hundred.

As the Andrew has a coupon of 20 percent, the 20 percent will be off whatever he buys. Now the discount price for the $16 priced CD is equal to the 20 percent of the 16. Thus the discount is,

[tex]d=\dfrac{16\times20}{100} \\ [/tex]

[tex]d=3.2[/tex]

Thus the discount on the CD is 3.2.

Now the discounted price of the CD is equal to the difference of the price of the CD and the discount. Thus the discounted price of the CD is,

[tex]P=16-3.2[/tex]

[tex]P=12.8[/tex]

Thus the discounted price of the CD is $12.8.

Answer:

£24.26 (rounded to 2dp) or full answ £24.255

Step-by-step explanation:

find 1% of 22.05= 0.2205

0.2205*10=2.205(10%)

add this to the 90%(£22.05+2.025)= 24.255

                                                          =24.26(rounded to 2dp)

The price of the lamp before the reduction will be £24.5.

What is mean by Percentage?

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

To Calculate the percent of a number , divide the number by whole number and multiply by 100.

Given that;

The sale price of the lamp = £22.05

This is a 10% reduction of the normal price.

Now,

Let the price of the lamp before the reduction = x

So, We can formulate;

⇒ x - (10% of x) = £22.05

⇒ x - 10x/100 = £22.05

⇒ (100x - 10x)/100 = £22.05

⇒ 90x / 100 = £22.05

⇒ 90x = £22.05 x 100

⇒ 90x = £2205

⇒ x = £2205/90

⇒ x = £24.5

Thus, The price of the lamp before the reduction will be £24.5.

Bao Yu first step to solve the equation is,

⇒ adding –3 to both sides of the equation

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The polynomial is,

⇒ x² - x - 3 = 0

Now,

We can solve the equation as;

⇒ x² - x - 3 = 0

⇒ x² - x - 3 + 3 = 3

⇒ x² - x = 3

⇒ x² - x + 1/4 = 3 + 1/4

⇒ (x - 1/2)² = 13/4

⇒ x - 1/2 = ±√13 / 2

⇒ x = ±√13 / 2 + 1/2

Hence, Bao Yu first step to solve the equation is,

⇒ adding –3 to both sides of the equation

The area of most three-dimensional geometric shapes is

A = a · h

Area = area of the base · height of the figure.

In this case, the area of the base is the area of a circle, so a = πr²:

a = 10²π

a = 100π ≅ 314

Now, all we have to do is multiply the area of the base to the height:

A = 100π · 6

A = 600π                            ← In terms of "π"

A ≅ 1884                             ← Rounded answer

x+40 = 90

x = 90-40

x = 50

Supplements add to 180

y = 180-63

y = 117

If the sum of the measures of two angles is 90° they are known as complementary angles.

According to the question

⇨x + 40° = 90°

The probability that neither of them draws the Leeks card is P = 4/6 = 0.667

Here we can assume that all the cards have the same probability of being randomly drawn.

The cards are:

So we have 6 cards. We want to find the probability that neither contestant draws the "Leeks" card.

Sammy draws first, the probability of drawing the Leeks card will be equal to the quotient between the number of Leeks cards (one) and the total number of cards (6).

Then the probability of drawing the leeks card is p = 1/6

This means that the probability of NOT drawing the leeks card is:

q = 1 - 1/6 = 5/6.

Now draws Hanna, now there are 5 cards in the deck (because one was already drawn). With the same approach as before, the probability of drawing the Leeks card is p = 1/5, then the probability of NOT drawing the card is:

q = 1 - 1/5 = 4/5.

The joint probability (this is, the probability of both of these events to happen together) is just the product of the individual probabilities.

Then the probability that neither of them draws the Leeks card is:

P = (4/5)*(5/6) = 4/6 = 0.667
