Answer:
c = 10
Step-by-step explanation:
Using Pythagoras' theorem
The square on the hypotenuse of a right triangle is equal to the sum of the squares on the other 2 sides, that is
c² = a² + b² ← substitute values
c² = 6² + 8² = 36 + 64 = 100 ( take the square root of both sides )
c = 
= 10
Answer:
A sample size greater than 30
Step-by-step explanation: The central limit theorem proffers the conditions necessary to obtain a normal or bell shaped distribution. It defines normal distribution in terms of mean, standard deviation and sample size. The sample size is a very important factor in determining the shape of a distribution.
Thus with a population having mean and standard deviation stated, in other to make use of or assume normal distribution, the sample size must be large. According tho the central limit theorem, a size of greater than 30 is deemed to be large enough. As the Same size increases, the sample mean converges to the value of the population mean.
Answer:
how to find the slope from a graph
Step-by-step explanation:
Answer:
x = 4 ± 
Step-by-step explanation:
Given
x² - 8x + 10 = 0 ( subtract 10 from both sides )
x² - 8x = - 10
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 4)x + 16 = - 10 + 16
(x - 4)² = 6 ( take the square root of both sides )
x - 4 = ± ( add 4 to both sides )
x = 4 ± ← exact solutions
