Mathematics

Length + width = 25cm
length = 25cm - width
length x width = 150 cm^2
(25cm-w)w= 150
25w-w^2=150
0=w^2-25w+150
0=(w-15)(w-10)
w=10cm
l=15cm

Answer:

the total amount is £756.

Step-by-step explanation:

given, monthly charge =£16

rate per min of call= £13 per min(150free calls )

rate per texts= £15per text (150 free text)

now, total calls made =170calls

total text = 180 text

now, minimum charge for 150 calls is free

so, left calls = 20 calls

charge for 20 calls= 20×£13

therefore, the charge for 20 calls is £260

now, for text

no. of text = 182-150=32

now, charge for 32 text =£ 15× 32

therefore the charge of 32 text is £ 480.

now, total amount = monthly charge + extra call charge+ extra text charge.

or, total amount = £16+£260+£480

=£756

<em>therefore</em><em>, </em><em> </em><em>the</em><em> </em><em>total</em><em> </em><em>amount</em><em> </em><em>is</em><em> </em><em>£</em><em>7</em><em>5</em><em>6</em><em>.</em>

<em>hope</em><em> </em><em>it</em><em> </em><em>helps</em><em>.</em><em>.</em><em>.</em>

Please helpppppp, i'm stuck
nata0808 [166]

Answer:

The operations you see with you eyes are multiplication and addition.

4 times X plus 2 = 10

The operations you don't see are Subtraction and Division.

4x+2=10

Subtract 2 from both sides.

4x+2−2=10−2

4x=8

Divide both sides by 4.

4x/4  =  8/4

x=2

Suppose the average tread-life of a certain brand of tire is 42,000 miles and that this mileage follows the exponential probabil
Ahat [919]

Answer: The probability that a randomly selected tire will have a tread-life of less than 65,000 miles is 0.7872 .

Step-by-step explanation:

The cumulative distribution function for exponential distribution is :-

P(X\leq x)=1-e^{\frac{-x}{\lambda}}, where \lambda is the mean of the distribution.

As per given , we have

Average tread-life of a certain brand of tire :  \lambda=\text{42,000 miles }

Now , the probability that a randomly selected tire will have a tread-life of less than 65,000 miles will be :

P(X\leq 65000)=1-e^{\frac{-65000}{42000}}\\\\=1-e^{-1.54761}\\\\=1-0.212755853158\\\\=0.787244146842\approx0.7872

Hence , the probability that a randomly selected tire will have a tread-life of less than 65,000 miles is 0.7872 .
