Answer:
0.729
Step-by-step explanation:
3.50÷7 = £0.50 per cake
5 cakes = 0.5 x 5 = £2.50
Since z is proportion to the x
z = a x
190 = a 10
a = 19
when x = 13
z = a x
z = 19 * 13
z = 247
The mode is the number that occurs the most so if you look at the numbers, thee only one that occurs twice is 5 so 5 is the mode.
