For example, a car was traveling at 60 miles per hour (mph) and hit another car, but there was hardly a dent. The reason is that the second car was traveling in the same direction at 59 mph, so the car was travelling only 1 mph with respect to the second car when the collision Speed<span> is how fast an object is going with respect to an object. </span>Velocity<span> is a measure of the speed in a given direction. You can say the top speed of an airplane is 300 kilometers per hour (kph). But its velocity is 300 kph in a northeast direction. We distinguish between speed and velocity because if you add the speeds of multiple objects, their directions are important. For example, the velocity of an airplane with respect to the ground would vary according to the direction of the wind.</span>
A. Assuming that the mean weights of wolves in the populations are equal, the probability of obtaining a test statistic that is greater than 2.771 or less than −2.771 is 0.01.
Aleena expands 2xx+3-5(x-2) as 2x²+3-5x-10. She is mistaken because the sign before 10 should be +10 instead of -10. Hence, the correct expanded form is 2x²+3-5x+10. Hence, this is the required solution.
