The value of z is \boxed{1.17} for the value of the cumulative standardized normal distribution at z is 0.8770.

Further explanation:

Given:

The cumulative standardized normal distribution is 0.8770.

Concept used:

The normal distribution that has mean zero and variance one is called as standard normal distribution.

The random variable X follows standard normal distribution with mean zero and variance one.

\boxed{X \sim N\left( {0,1} \right)}

Then the value of z can be obtained as,

\boxed{Z = \frac{{X - \mu }}{\sigma }}

Calculation:

The normal distribution is symmetric.

The standard normal distribution is bell shaped curve and it also a symmetric curve.

The cumulative standardized normal distribution is 0.8770 it is area under the curve.

The probability of a number less than z value is 0.8770.

From the z table the approximate value of the z is \boxed{1.17}.

Kindly refer to the image attached.

<span>The value of z is 0.8770. This answer was derived from information in the question, which states that the value of z is 0.8770. Granted, I don't understand what is meant by "cumulative standardized normal distribution." I only passed statistics because the professor felt sorry for me.</span>

Answer:

A.) (7t³ + 2k^4)(7t³ - 2k^4)

Step-by-step explanation:

Factor the following:

49 t^6 - 4 k^8

49 t^6 - 4 k^8 = (7 t^3)^2 - (2 k^4)^2:

(7 t^3)^2 - (2 k^4)^2

Factor the difference of two squares. (7 t^3)^2 - (2 k^4)^2 = (7 t^3 - 2 k^4) (7 t^3 + 2 k^4):

Answer:  (7 t^3 - 2 k^4) (7 t^3 + 2 k^4)
