Answer: The mean temperature for the first eight days is 6.5 degrees
Step-by-step explanation: The most important piece of clue has been given which is the mean (average) for the observed data set, which is 7 days.
Note that the formula for the mean of a data set is derived as;
Mean = ∑x / f
Where ∑x is the summation of all observed data set and f is the number of data observed, that is 7. The formula now becomes;
6 = ∑x / 7
By cross multiplication, we now have,
6 * 7 = ∑x
42 = ∑x
This means the addition of all temperature observed on the first 7 days is 42. The temperature on the eighth day is now given as 10 degrees, this means the summation of all observed data for the first eight days would become 42 + 10 which equals 52. Therefore when calculating the mean for the first eight days, ∑x is now 52. The formula for the first eight days therefore is derived as follows;
Mean = ∑x / 8
Mean = 52 / 8
Mean = 6.5
The calculations therefore show that the mean temperature for the first eight days in January is 6.5 degrees
Answer:
88
Step-by-step explanation:
Looks close to a right angle so 88 degrees most likely.
Answer:
a)5/9 yards=0.556yards
b)10/9 yards=1.11 yards
Step-by-step explanation:
for the part a
To solve this exercise we must divide the total distance traveled by the grasshopper (5 yards) by the number of jumps that were made (9).
if you use the calculator you will realize that the value is 0.55yards
for the part b
knowing the distance traveled in a jump, we multiply this value by two to find out how much is the distance traveled in 2 jumps
if you use the calculator you will realize that the value is 1.11 yards
