Answer:
Step-by-step explanation:
in supplementary angle sum of two angles is always 180 degree
let another angle be x
x+151=180
x=180-151
x=29 degree
There is 12 inches in 1 ft......so in 66 inches.....66/12 = 5.5 ft or 5 1/2 ft or 5 ft 6 inches
Answer:
359.19
Step-by-step explanation:
Using the formula V=(πr^2) * h/3 and plugging in the given values we get 359.19.
I estimated pi at about 3.14
We have been given that a set of average city temperatures in May are normally distributed with a mean of 20.66°C and a standard deviation of 2 C. The average temperature of Singapore is 26°C. We are asked to find the proportion of average city temperatures that are lower than that of Singapore.
First of all, we will find z-score corresponding to sample score of 26.
, where,
z = z-score,
x = Random sample score,
= Mean,
= Standard deviation.
Now we need to find probability of a z-score less than 2.67 that is .
Using normal distribution table, we will get:
Upon rounding to 4 decimal places, we will get:
Therefore, approximately of average city temperatures are lower than that of Singapore.
