Answer:
4w^2 +4w+1
this is the product.
Step-by-step explanation:
15% of 25 is the greatest of the two.
Answer:
25% of 15 is 3.75
15% of 25 is also 3.75
15 - 3.75 = 11.25
25 - 3.75 =21.25
Compare and then determine.
11.25 < 21.25

4x^2 + 11x + 6 = (4x + 3)(x + 2)
9x^2 - 4 = (3x +2)(3x - 2)</span>
Hey! I'll provide the steps required.
First, solved the proportion by cross multiplication.

Then use the commutative property to reorder the terms as well as multiply the numbers.
90x = 9720
Finally, divide it by 90.
x = 108
Answer:

Step-by-step explanation:
Given
The above table
Required
The standard deviation
First, calculate the class mid-point. This is the average of the class interval.
The mid-point x is:





So, we have:

Calculate mean




The standard deviation is:
