Answer:

In a standardized normal distribution the mean is 0 while the standard deviation is 1.

What is standardized normal distribution ?"Standardized normal distribution is also known as z - distribution curve where value of mean is always zero and value of standard deviation is 1."

As per the statement given,

In a standardized normal distribution the mean is 0 while the standard deviation is 1.

- This distribution helps to divide data into different category and allow to calculate the probability which is present in the conditional distribution.
- It helps to compare the data with the mean and standard deviation.

Hence, Option(B) is the correct answer.

What is the rate of change between the points (-3, 0) and (-2, -5)?

The rate of change is the change in Y over the change in X.

Rate of change = (-5 - 0) / (-2 - -3)

Rate of change = (-5 ) / (-2+3)

Rate of change = -5 /1

Rate of change = -5

X/5 +8=3 what would x be

Answer: x= -25

Step-by-step explanation:

Answer:

x=-25

Step-by-step explanation:

x/5 = 8 = 3 you would multiply both sides by 5

youd end up with x+40=15 then you would move the constan to the right

x=15-40 you would subtract 40 from 15

x=-25

How many complex roots does the equation 0=2x^3-4x^2-x+1 have

Answer:

No complex roots; 3 real roots

Step-by-step explanation:

If a third order polynomial has any complex roots, then as a rule it has 1 real root and 2 complex roots. In this particular case, the polynomial has three real roots, as can be determined by graphing the function. The graph crosses the x-axis in 3 places.

Answer:

The Answer would be 3 complex roots.

For what values of x does 25 Superscript x Baseline = 5 Superscript x squared minus 3?

For this case we have the following equation:

Rewriting we have:

For expressions to be equal, exponents must be equal. So:

To factor, we look for two numbers that, when multiplied, result in -3 and when added, result in -2. These numbers are -3 and 1.

Thus, the roots are:
