Answer:
0.9962
Step-by-step explanation:
The z score shows the number of standard deviations by which the raw score is above or below the mean. If the raw score is above the mean then the z score is positive but if the raw score is less than the mean then the raw score is negative. The z score is given by:

μ = 20.66°C, σ = 2°C
For x < Singapore temperature, i.e. x < 26

From the normal distribution table P(x < 26) = P(z < 2.67) = 0.9962

Because the denominators are same, you can just add the numerators.

they can be any shape the baker wants to be.
Answer:
if it right angled
m<4+m<8=90
