(7x^3y^2)(4x^3y^2)^=exponentssolve in scientific Notation

Mathematics

<h3>Answer:</h3>

(2.8×10¹)x⁶y⁴

<h3>Step-by-step explanation:</h3>

Multiplication can be done in the usual way, then the number converted to scientific notation. Scientific notation does not apply to the variables.

(7x^3y^2)(4x^3y^2)=(7\cdot 4)x^{3+3}y^{2+2}=28x^6y^4\\\\=2.8\cdot 10^1x^6y^4

_____

If you write the numbers in scientific notation to start, then do the multiplication, the effect is virtually the same: an adjustment is needed in the product to get it back to scientific notation.

(7)(4) = (7×10⁰)(4×10⁰) = 7·4×10⁰⁺⁰ = 28×10⁰ = 2.8×10¹

What is the probability that a student eye color would be blue if their grade in physics is A? A two way table is presented belo
Zarrin [17]
The <u>correct answer</u> is:

16/45.

Explanation:

We want the probability that a student's eye color is blue if they made an A in physics.  This means we look at the column for students with an A.

There are 32 students with blue eyes in the A column.

This is out of 32+58=90 students that made an A.

This makes the probability 32/90, which simplifies to 16/45.
