Answer:
b= 1421/956
Step-by-step explanation:
- 9.14b +0.42 = 9.56b
- 9.56b - 8.3 = 5.91
- 9.56b= 5.91 +<u>8</u><u>.</u><u>3</u>
- 9.56b = 14.21
- Now devide both sides by 9.56
- Your Final answer is: b= 1421/956
Answer:
165
Step-by-step explanation:
First, we multiply 50 and 2 to find out how much they traveled first, which is 100. And then, multiply 65 and 1 to get 65 for the second part. Add then, to get 165. Hope this helps!
Answer:
MAD is 5.12
Step-by-step explanation:
The following data were obtained from the question:
42, 50, 54, 38, 48
Next, we shall determine the mean of the data. This can be obtained as follow:
Mean = summation X / n
n is the number of the data.
Summation X = 42 + 50 + 54 + 38 + 48
Summation X = 232
n = 5
Mean = summation X / n
Mean = 232 / 5
Mean = 46.4
Therefore, the mean of the data is 46.4
Finally, we shall determine the mean absolute deviation (MAD) of the data as follow:
MAD = summation |mean – X| /n
MAD = (|(46.4 – 42) + (46.4 – 50) + (46.4 – 54) + (46.4 – 38) + (46.4 – 48|) /5
MAD = |4.4 + 3.6 + 7.6 + 8.4 + 1.6| /5
MAD = 25.6/5
MAD = 5.12
Therefore, the mean absolute deviation (MAD) is 5.12
6 14 miles in 5 days.
In 1 day Tom rides 6 14/5 = 1 228 miles
1 week has 7 days
5 weeks have 35 days
1 day Tom rides 1 228 miles
35 days Tom rides for 1 228 * 35 = 42 98miles.
Answer:
The first four terms in the sequence 57, 50, 43, and 36
Step-by-step explanation:
Put the numbers in place of x (or n in this case).
You subtract that number you put in place of n by 1.
You then distribute the difference of n and 1.
You then subtract the distributed number by 57
