Answer:
angle ABC= 2* 61= 122
Step-by-step explanation:
In a meter there are 100 cm.
In 100 cm there are 1000 mm.
Therefore in 1 meter you have 1000 millimeters.
Then to find out how many millimeters you have in 14 meters, you just multiply 14 by 1000 to give you 14000 mm.
Final answer= 14 m of gold wire is the equivalent to 14000 mm of wire.
Answer:
4.25
Step-by-step explanation:
Here in this question, we want to calculate the mean absolute deviation of the data.
The first thing we will do here is to calculate the mean;
= (74 + 79 + 76 + 85 + 87 + 83 + 86 + 78)/8 = 81
Now, the next thing to do here is to calculate how far each of the values have deviated from the mean. This can be calculated by subtracting the mean from each individual value;
This is presented in the table on the attachment, please check attachment for this
Afterwards, we find the absolute value of all these subtractions then divide by 8 which is the number of values in the data.
Mean absolute deviation = Sum of all absolute deviations/number of values in dataset
