Question

Please help !! <33

u) a=42 correct to 2 sig figs. b = 24 correct to 2 sig figs. c = 14 correct to 2 sig figs. work out the lower bound for the value of y. give your answer correct to 2 sig figs.
y = 2a/b-c
(I attached a sc to this question if its hard to read)

Answer 1

23

Explanation:

Answer 2

The lower bound for the value of y is 8.3.

The lower bound for the value of y can be found by substituting the lower bounds for a, b, and c into the formula given:

y_lower bound = 2a/b-c

By using the lower bound values of a = 41.5, b = 23.5, and c = 13.5.

y_lower bound = (2 × 41.5) / (23.5 - 13.5)

y_lower bound = 8.3

Therefore, the lower bound for the value of y is 8.3 (correct to 2 significant figures).
