Answer:
960
Step-by-step explanation:
3/8*total number of animals = 600
total number of animals = 8/3 * 600 = 1600
number of animals fed = 40/100 * 1600 = 640
animals still to be fed = 1600 - 640 = 960
Answer:
The standard error of the mean is 4.5.
Step-by-step explanation:
As we don't know the standard deviation of the population, we can estimate the standard error of the mean from the standard deviation of the sample as:
The sample is [30mins, 40 mins, 60 mins, 80 mins, 20 mins, 85 mins]. The size of the sample is n=6.
The mean of the sample is:
The standard deviation of the sample is calculated as:
Then, we can calculate the standard error of the mean as:
A) The perimeter is the length around the rectangle, so it would be 2 + 5 + 2 + 5 = 14m
The area is 2m * 5m = 10m^2
b/c) You have to draw a rectangle with a perimeter of 14m, and an area that ISN'T 10m^2. You could draw a 3m by 4m rectangle which would have a perimeter of 14m and an area of 12m^2.
Answer:
DB = 13 cm
Step-by-step explanation:
ΔCAB ≅ ΔDBA by ASA, so CA ≅ DB by CPCTC.
CA = 13 cm, so DB = 13 cm.
