Black_prince [1.1K]

Answer:

0.98046

Step-by-step explanation:

Given:

  • μ = 5.67
  • σ = 0.07

Here we are required to find

P(5.48 <X<5.82) and between 5.48 and 5.82 we each z-score given by

<em>z = (x - μ) / σ</em>

So 5.48 we have z = -2.714  and 5.82 we have  z = 2.143

Therefore we have the area of interest on the normal distribution chart given by :

P( -2,714 < z < 2.143)

= 1 - P(Z<-2.714) + P(Z >  2.143)

= 1 - P(Z<-2.714) + (1 - P(Z <  2.143))

= 1 - 0.00336 + 1 - 0.98382

= 1 - 0.01954 = 0.98046

... a = √175 = √(25·7)

... a = 5√7

Why does the associative property work with addition but not subtraction?
lbvjy [14]

Answer:

Contrary to addition, subtraction doesn't have the associative property. If we subtract the first two numbers, 10 minus 5, it gives us 5. ... Changing the way of associating the numbers in subtraction changes the answer. Thus, subtraction doesn't have the associative property.
