A bag contains a mixture of identical coloured balls. The probability of selecting a blue ball from the bag is 0.4
(a) Calculate the probability of not selecting a blue ball
(b) If there are 80 balls in the bag, calculate how many are not blue

a) 0.6

b) 48

Step-by-step explanation:

a) 0.4 = 40%.

100% - 40% = 60% = 0.6

b) 0.6 (60%) are not blue.

0.6 x 80 = 48.

a, b, c, d are correct.

step-by-step explanation:

we have g(x) = 3 and are required to find which option is a translation of g(x).

now, 'translation' is a transformation which means to shift the function in any direction and the general form of translation is g(x) + k, where k is any real number.

so, according to the options we see that all are correct as they satisfy the general form of translation.

also, it can be seen from the graph below that the function g(x) = 3 is shifted from its position in all the four options.
