an verage person has 6x10^2 times as many red bloods cells as white blood cells. A small sample of blood has 7x10^3 white blood
m_a_m_a [10]

Answer:

4.2 x 10⁶

Step-by-step explanation:

The problem says that there are 6x 10² times as many red blood cells as white blood cells. This means that you will need to multiply the given number of white blood cells, which is 7 x 10³ by 6x 10².

To do this, first you multiply the coefficients:

7 x 6 = 42

Next you combine the exponents of the 10s, because their bases are the same, we just add the exponents when you multiply them and copy the base:

10² x 10³ = 10⁵

So the result would be:

42 x 10⁵

However the following the form of scientific notation, you need to move the decimal one more time so that means you add one more to the exponent of 10.

4.2 x 10⁶

What is the median of the following set of numbers?
Gnesinka [82]
21, 45, 121, 300, 312, 333, 347, 421, 614,

The median is the middle number of a data set therefore you need to arrange the data is order from smallest to largest as I have done above. Then you need to find the number in the middle which is 312 in this case by finding the number which has the central position (position 5 in this case) of the data set. If there are an even number of numbers in the data set, you add them together and divide by 2 though that is not necessary this time as there are an odd number of numbers.
