<span>Angle T = Angle C, let them equal x
So x + x + 140 = 180
2x = 40
x = 20
So Angle T = 20 degrees </span>
5
2 = 32
Exponents are like a simplified or easier version of multiplying
2*2*2*2*2
People use exponents in real life. For an example, they use it for finding cubic feet ,square feet, or area of something or an object.
Sorry if I am bad at explaining this or if I confused you
Answer:
Step-by-step explanation:
Given: 76,45,64,80,92
Required: Determine the standard deviation
We start by calculating the mean
Where x-> 76,45,64,80,92 and n = 5
Subtract Mean (71.4) from each of the given data
Determine the absolute value of the above result
Square Individual Result
Calculate the mean of the above result to give the variance
Hence, Variance = 255.298
Standard Deviation is calculated by
