For a standard normal distribution, the expression that is always equal to 1 is P(z≤-a)+P(-a≤z≤a)+P(Z≥a). This expression represents all of the possible values in a curve, or in other words, the total area of a curve. According to standard normal distribution, the total area of a curve is always equal to 1.

A investor obtained a loan of $600,000 to buy a car wash business. The monthly mortgage payment was based on 30 years at 5.5%. F
Lisa [10]

Answer:

The monthly mortgage payment is $ 8306.58

Step-by-step explanation:

Given as :

The loan taken as $ 600,000

The rate of interest = 5.5 %

The time period = 30 Years

So, from compounded method

Amount = principal × (1 +\frac{Rate}{100})^{Time}

or, Amount = $ 600,000 × (1 +\frac{5.5}{100})^{30}

Or, Amount =  $ 600,000 × (1.055)^{30}

∴   Amount = $ 2990370.77

<u>Now for The monthly mortgage payment </u>

∵ Time period is 30 years

So , 30 years = 12 × 30 = 360 months

∴ Amount payment in monthly =$ \frac{2990370.77}{360}

Or, Amount payment in monthly =$ 8306.58

Hence The monthly mortgage payment is $ 8306.58   Answer

Westkost [7]
Okay.  You have 15 lbs of concrete, and x bags that can individually hold 2.5 lbs.  What you need to do is divide 15 by 2.5, and the quotient will be 6.
Problem:  15 ÷ 2.5 = 6
So the answer to your problem will be: 6 bags.
