Answer:

£27

Step-by-step explanation:

From the above question, we know that:

The price of a shirt is usually = £45. During a sale the prices in the shop are reduced by 2/5 .

Hence, the amount that the cost of tht shirt is reduced by is :

£45 × 2/5

= £18

The cost of this shirt in the sale is calculated as:

£45 - £18

= £27

Answer:

I believe it is 6 days.

The total number of days all crew needs to pour concrete is 6 days consecutive.

What information do we have?

Total number of crew = 3

Total yards = 175,000

Each crew pour concrete per hour = 1200

Total concrete pour per day = 1200 × 3 × 8

Total concrete pour per day = 28,800 yard

Total number of days crew pours concrete = Total yards / Total concrete pour per day

Total number of days crew pours concrete = 175,000 / 28,800

Total number of days crew pours concrete = 6.076

Total number of days crew pours concrete = 6 days

Step-by-step explanation:

because 4 times 2.5 equals 10, we multiply 6 by 2.5 too

Step-by-step explanation:

sin²x = 2 - 2cosx

1 - cos²x = 2 - 2cosx (because sin²x + cos²x = 1)

cos²x - 2cosx + 1 = 0

(cosx - 1)² = 0

cosx - 1 = 0

cosx = 1

Hence x = 0.

Answer:

15/100 * 450 = 67.5 (discount)

450 - 67.5 = 382.5 (sale price)

7/100 * 382.5 = 26.775 (7% tax)

26.775 + 382.5 = 409.275 (final price)

Answer:

44

Step-by-step explanation:

44÷5 is 8.8 which is greater than 7

Answer:

x=44

Step-by-step explanation:

Divide each number by 5

-44/5 = -8.8

34/5 = 6.8

44/5=8.8

-34/5=-6.8

8.8 is the only one greater than 7 so 44 is the only one that satisfies the inequality

Answer:

The probability none mechanical engineering majors is 0.03967.

Step-by-step explanation:

Given that,

Total students = 125

Number of students in computer science = 28

Number of students in mechanical engineering = 52

Number of students in civil engineering= 12

Suppose six students from the class are chosen at random what is the probability none are mechanical engineering majors?

We need to calculate the probability none are mechanical engineering majors

Using given data

None mechanical engineering majors = [tex]\dfrac{125-52}{125}=0.584[/tex]

If six students from the class are chosen at random then

The probability none are mechanical engineering majors will be

[tex]P_{nme}=(0.584)^6[/tex]

[tex]P_{nme}=0.03967[/tex]

Hence, The probability none mechanical engineering majors is 0.03967.

Answer:

120ways

Step-by-step explanation:

This question bothers combination. Combination has to do with selection.

Given

Total number of brands = 10

If we the service is to rank the top 3, this can be done in 10C3 number of ways.

10C3 = 10!/(10-3)!3!

10C 3 = 10!/7!3!

10C3 = 10*9*8*7!/7!3!

10C3 = 10*9*8/6

10C3 = 720/6

10C3 = 120

Hence it will take 120ways for the consumer testing service to arrive at the final ranking
