If data collected shows that 95% of the cars travel at the speed of less than 140 k m/h and 10% travel at the speed less than 90 km an hour what is the average speed and the SD for the cars traveling on that specific stretch of the highway?

Ahigh-altitude spherical weather balloon expands as it rises, due to the drop in atmospheric pressure. suppose that the radius r increases at the rate of 0.02 inches per second, and that r = 36 inches at time t = 0. determine the equation that models the volume v of the balloon at time t, and find the volume when t = 360 seconds. v(t) = 4π(0.02t)2; 651.44 in3 v(t) = 4π(36 + 0.02t)2; 1,694,397.14 in3 v(t) = four pi times the product of zero point zero two and t to the third power divided by three.; 4,690.37 in3 v(t) = four pi times the quantity of thirty six plus zero point zero two t to the third power divided by three.; 337,706.83 in3

Could these triangles be congruent? yes, if ab - deyes, if bc = 7yes, if ab - efno, because the hypotenuses must have different lengths
