Answer:
Step-by-step explanation:
x+3y=1
<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>
The sum of the numbers should total to 1. Let us say that
x is the missing number, therefore:
x + ¼ + ¼ + 1/5 = 1
x = 1 – ¼ - ¼ - 1/5
The numbers should have similar denominator:
x = 20/20 – 5/20 – 5/20 – 4/20
x = 6/20
<span>x = 3/10</span>

==================================
What is the product of (2x-7) and (3x + 3)?
- A. 6x2 + 15x-21
- B. 6x2 - 15x - 21
- C. 6x2 + 15x + 21
- D. 6x2 - 15x + 21
==================================
*Please read and understand my solution. Don't just rely on my direct answer*
==================================
Here we have the given choices:
- A. 6x2 + 15x-21
- B. 6x2 - 15x - 21
- C. 6x2 + 15x + 21
- D. 6x2 - 15x + 21
Solve this equation using the distributive property,where you multiply each term to get the number.
Therefore, the correct option is letter B.
