Both the first choice and the fourth choice are correct because the sum of supplementary angles is 180°
shoe size of certain age groups would be the best way
Step 1: arrange the data points in order
12 14 24 30 35 40 42 50 53 Step 2 : Find the median.
median is 35. Step 3. divide the data points into two : left and right
of median
12 14 24 30 and 40 42 50 53
Step 4: find median of each12 14 24 30 : (14+24)/2 = 1940 42 50 53 : (42+50)/2 = 46
step 5. draw lines on the scale on the median, two other
medians and least and the greatest value
Answer is B.
You can solve this using trigonometric functions.
The angle between the fish and the ground is
tan θ = 100 / 50
θ = tan-1 (2)
θ = 63.43°
The height of the bird before it dropped the fish is already given, which is 100 yards.
Answer:
The median length of all pregnancies will be 266 days.
Step-by-step explanation:
We have been given that the length of human pregnancies varies normally with a mean of 266 days and a standard deviation of 16 days. We are asked to find the median length of all pregnancies.
We know that mean, median and mode all are equal for normal distribution.
Since we are told that the length of human pregnancies varies normally, therefore, the median length of all pregnancies will be same as mean that is 266 days.
