MISCELLANEOUS EQUATIONS A die is rolled and a coin is tossed. Find the probability of picking a tail or 3. A bag contains 4 green balls and 3 blue balls given that 2 balls are picked at random one at or time without replacement, find the probability that one of the balls is green. Given that , evaluate. Given that Find (i) (ii) By use of elimination method, solve the simultaneous equation below. The circle below has its centre at O. Find angles K and L. Make q the subject of the formular from, If and that Find the value of Given that. Make x the subject of the formula The line cuts the y-axis at . Find ;(i)the gradient of the line (ii) the value of k. Box A had cards marked with 2, 3 and 7 while Box B had cards marked with 4, 6 and 8. Two cards are to be picked at random, one from each box and one would get a prize if the sum of the numbers on the cards is at least more than 10. Draw a table showing the sample space. Find the probability that Sarah failed to get the prize. The line passes through point . Determine its gradient value of P. A piece of land of area 45km2 is represented on a map of scale . What is the area of the land on the map in cm2? Express with a rational denominator hence evaluate (to 2dp) without using tables or calculator, given that = 1.414. Express in the simplest form of , hence find Determine the base used in the equation = Find the equation of the line passing through point which is perpendicular to the line whose equation is Express in the form + and hence state the …
