times tables

Let us now find out how Time Period of oscillation vary with time. Set up a simple pendulum and measure the time taken for 10 oscillations of the simple pendulum for different lengths like 10,20,40,60,80 and 100 cm. Time period of a pendulum varies with th..

The table shows the number of hours spent by Tom in his office per day. If he continued to spend time in his office in the pattern shown, how many hours did he spend in his office on the first day? Day of the month 1 2 3 4 5 Time spent (in hours) - 9 11 14 18 => 18 hou..

Andrew played a maze game 9 times. There are 5 ways to exit the maze. The table shows the different ways Andrew went through the maze to exit. Way to exit Number of times Andrew went through the way Way A 3 Way B 2 Way C 1 Way D 3 Way E 0 Express as a fraction, the num..

Jimmy tossed a coin 24 times and recorded the outcomes as shown in the table. Outcome Number of Occurrences Head 9 Tail 15 What is the experimental probability of getting a head? => 3 8 or 4 5 or 7 8 or 11 10..

A survey revealed the following details in the table, which shows the time taken by each of the persons to prepare a breakfast. Find the experimental probability of choosing a person who takes more than 20 minutes to prepare the breakfast. Person Time taken (in minutes..

The observed frequencies in rolling a die 102 times are: Face 1 2 3 4 5 6 Observed Frequency 14 16 16 17 20 19 Using a significance level α = 0.05, find the chi-square test value and can you regard the die as a fair one? => 11.1, the die is fair or 1.412, the die is fair or 11.1, th..

Time also has a wide range of values. They are tabulated below in the order of their magnitude. Event Order of magnitude of time interval (s) Time taken by light to cross distance of nuclear size [time proportion to revolve once in nucleus] 10 -..

Velocity-Time Graph - The variation of velocity with time can be represented graphically to calculate acceleration exactly like we calculated speed from distance-time graph. Let us now plot a velocity-time (v - t) graph for the following data. Velocity in m/s..

The frequency table displays the number of students of a class who spend varying amounts of time for doing their homework. Find the range of the data. Time (in min) Frequency 15 7 20 15 25 17 30 3 35 14 40 2 => 2 or 17 or 19 or 15..

Multiply: 8 7 4 × 6 => 5,244 or 890 or 880 or 5,344..
