Material for a dress costs £5.50 per metre.<br> find the cost of 10cm and 70cm

Zielflug [23.3K]

Answer:

<em>The cost of 10 cm and 70 cm are £0.55 and £3.85 respectively.</em>

Step-by-step explanation:

Material for a dress costs £5.50 per meter.

We know that, <u>1 meter = 100 cm</u>.

Suppose, the cost of 10 cm material is $x$ and the cost of 70 cm material is $y$

Now, <u>according to the ratio of "cost" to the "length of material"</u> , we will get.......

$\frac{x}{10} =\frac{5.50}{100}\\ \\ 100x=10*5.50=55\\ \\ x=\frac{55}{100}=0.55$

and

$\frac{y}{70} =\frac{5.50}{100}\\ \\ 100y=70*5.50=385\\ \\ x=\frac{385}{100}=3.85$

So, the cost of 10 cm material is £0.55 and the cost of 70 cm material is £3.85

Chegg: Amoung 400 randomly selected drivers in the 16-18 age bracket, 206 were in a car crash in the last summer. If a driver in

Digiron [165]

The probability of a car crash is 56.75

Approx probability of car crash = 227/400 = 0.5675 i.e. 56.75%

This probability is high enough to be of concern to those in the 16-18 age bracket because the probability is not unlikely.

Probability is the department of mathematics concerning numerical descriptions of the way in all likelihood an occasion is to occur, or how probable it's miles that a proposition is actual. The probability of an occasion is more than a few between zero and 1, in which, kind of talking, 0 indicates impossibility of the occasion and 1 shows actuality.

The probability of an occasion can be calculated through chance system via simply dividing the favorable range of results by using the overall number of possible results.
