To solve the problem, we need to determine the probability that a tire from the company will need to be replaced before it has covered a distance of 4000 kilometers. ### Step-by-Step Solution: 1. **Understand the Data**: The company has recorded the distances covered by tires before they need to be replaced. The frequency of tires needing replacement is given in the following ranges: - Less than 4000 km: 20 tires - 4000 to 9000 km: 210 tires ...

Xia is charging her laptop. She records the battery charge for the first 30 minutes after she plugs it in to get an idea of when it will be completely charged. The table above shows the results. If y is the percent battery charge on Xia's laptop, which linear equation represents the correct relationship between y and x ?

A vehicle of mass 500 kg is moving with a velocity of 15ms^(-1) . It is brought to rest by a retarding force. Find the distance moved by the vehicle before coming to rest, if the sliding friction between the tyres and the road is 3000N.

The coefficient of friction between the tyres and road is 0.4. The minimum distance covered before attaining a speed of 8 ms^(-1) starting from rest is nearly ( take g=10 ms^(-2) )

We wish to obtain an equal sized inverted image of a candle flame on a screen kept at a distance of 4 m from the candle flame. (a) Name the type of lens that should be used. (b) what should be the focal length of the lens and at what distance from the candle flame the lens be placed ? (c) Draw a labelled diagram to show the image formation in this case.

As mosquito is sitting on an L.P. record disc rotating on a trun tabel at 33 1/3 revolutions per minute. The distance of the mosquito from the centre of the turn table is 10 cm. Show that the friction coefficient between the record and the mosquito is greater than pi^2/81 . Take g=10m/s^2

A student performs an experiment to determine how the range of a ball depends on the velocity with which it is projected. The "range" is the distance between the points where the ball lends and from where it was projected, assuming it lands at the same height from which it was projected. It each trial, the student uses the same baseball, and launches it at the same angle. Table shows the experimental results. |{:("Trail","Launch speed" (m//s),"Range"(m)),(1,10,8),(2,20,31.8),(3,30,70.7),(4,40,122.5):}| Based on this data, the student then hypothesizes that the range, R, depends on the initial speed v_(0) according to the following equation : R=Cv_(0)^(n) , where C is a constant and n is another constant. The student performs another trial in which the ball is launched at speed 5.0 m//s . Its range is approximately:
