Answer:

z-score for 900 points = -4

Step-by-step explanation:

To find the z scores

z=(x-mean)/standard deviation

so

z=(900-1500)/150

z= -600/150

1.06t can be written as (1.061/2)2t to give the approximate equivalent monthly interest rate based on an annual rate of 6%. Use

Tema [17]

Answer: $1.06^t$ .

Step-by-step explanation: We are given expression $1.06^t$ .

And $1.06^t$ expression is converted in $(1.06^{1/2})^{2t}$ .

Now, we need to transform the expression into a single exponent expression using the properties of exponents.

We know, according to the properties of exponents

$(a^m)^n = a^{m\times n}$

Applying same rule in given expression, we get

$(1.06^{1/2})^{2t} = (1.06)^{\frac{1}{2} \times 2t}$

On simplifying exponents, we would get t in exponent.

= $1.06^t$ .
