For un = (2n + 1)3 − (2n − 1)3, (i) suggest an expression for ; (ii) prove it using the definition of u.
The two bounds to verify are and . Again un = (2n + 1)3 − (2n − 1)3. (i) Express u_n as a quadratic in v = 2n + 1. (ii) Hence express in terms of T2(n), T1(n), T0(n). (iii) Hence show that…
Find, in terms of r, (i) the arc length UV; (ii) hence the perimeter of the insert.
The insert has perimeter 20 cm. Find r.
The insert has perimeter 20 cm. Hence find the insert’s area.
State the mode.
Find (i) the mean; (ii) the median; (iii) the population standard deviation.
Draw a box-and-whisker plot on the scale provided.
Initially w=3, p=1/3 and charge is 1. (i) Show that the probability a of still running with charge 1 after exactly two ticks is 2/9. (ii) Find the probability b that full charge is reached for the first time on tick 4.
Under the same w=3, p=1/3 settings, a run is still active at charge 1 after tick 4. State the probability that it is again active at charge 1 after the next two ticks.
