About ____% of the area is between z= -2 and z= 2 (or within 2 standard deviations of the mean)

never [62]

Answer:

<em>The percentage of area is between Z =-2 and Z=2</em>

P( -2 ≤Z ≤2) = 0.9544 or 95%

Step-by-step explanation:

<u><em>Explanation:-</em></u>

Given data Z = -2 and Z =2

The probability that

P( -2 ≤Z ≤2) = P( Z≤2) - P(Z≤-2)

= 0.5 + A(2) - ( 0.5 - A(-2))

= A (2) + A(-2)

= 2 × A(2) (∵ A(-2) = A(2)

= 2×0.4772

= 0.9544

<em>The percentage of area is between Z =-2 and Z=2</em>

P( -2 ≤Z ≤2) = 0.9544 or 95%

Z minus one third equals one and two thirds

Ainat [17]

First you rewrite 1 2/3 into an improper fraction: z-1/3=5/3
Then you have: z-1/3=5/3
Move -1/3 to the right side of the equation by adding 1/3 to both sides.
z=1/3+5/3
Simplify the right side by combining the numerators over the common denominator: z=(1+5)/3
Add 1 and 5 to get 6: z=6/3
Divide 6 by 3 and get 2

z=2

What are the real zeros of the function g(x) = x3 + 2x2 − x − 2?

Diano4ka-milaya [45]

For this case, to find the roots of the function, we equate to zero.

$x ^ 3 + 2x ^ 2-x-2 = 0$

We rewrite how:

$x ^ 3 + 2x ^ 2- (x + 2) = 0$

We factor the maximum common denominator of each group:

$x ^ 2 (x + 2) -1 (x + 2) = 0$

We factor the polynomial, factoring the maximum common denominator $(x + 2):$

$(x + 2) (x ^ 2-1) = 0$

By definition of perfect squares we have to:

$a ^ 2-b ^ 2 = (a + b) (a-b)$

ON the expression $(x ^ 2-1):$

$a = x\\b = 1$

So:

$(x ^ 2-1) = (x + 1) (x-1)$

Thus, the factorization of the polynomial is:

$(x + 2) (x + 1) (x-1) = 0$

$x_ {1} = - 2\\x_ {2} = - 1\\x_ {3} = 1$

ANswer: $x_ {1} = - 2\\x_ {2} = - 1\\x_ {3} = 1$
