The answer would be the algebraic expression, b + 9. The
translation here is b is representing the number of blue bikes then you needed
to add the 9 which represents the 9 red bikes. The two is added together, to get
the total of those red and blue bikes which we are looking for.
Answer:
- 0.5 - 1.7 = - 2.2
Step-by-step explanation:
We need to add two numbers using the number line.
Steps to Add Numbers on the Number Line:
When we add a negative numbers that we move the point to the left of the number line.
We are adding two negative numbers. Locate the first number which is -0.5. Then, add negative 1.7 to it which means moving the existing point 1.7 units to the left of the number line.
So, we get 2.2 on the left.
2.2 is left side it means sign is negative.
Final answer is -2.2
Answer:

This question will be solved using the finite correction factor
First, calculated the z score
So:
Using z table
(5,3) is the answer for the current question
x - 12/6 = 9
x - 1/2 = 9
x = 9 + 1/2
x = (9/1)×2 + 1/2
x = 18/2 + 1/2
x = 19/2 = 9.5
