The width of a red blood cell is approximately 8 micrometers, which is 8 x 10-6 meter. give your answers to the questions below in scientific notation. be sure to answer both a and b, and explain your answer to b.

a. what would be the width of 7.2 x 105 red blood cells in meters?

b. if a grain of salt is .5mm wide, how many red blood cells could fit across one grain of salt? explain your answer. (hint: 1mm = 1 x 10-3 m.)

A)  

B)  62

Step-by-step explanation:

The width of a red blood cell is approximately 8 micrometers meters

Part A)

Width of 1 red blood cell meters

width of red blood cells meters

Now change into scientific notation. So, decimal should be between 1 to 10

Decimal move 1 digit right to left

Hence, the width of red blood cells is

Part B)

If a grain of salt is 0.5 mm wide.

First convert mm to m. ( 1 mm = 1 × 10⁻³ m)

Therefore, 0.5 mm = 5 × 10⁻⁴ m

Size of a grain = 5 × 10⁻⁴ m

Size of a blood cell = 8 × 10⁻⁶ m

Hence, 62 number of red blood cells fit in a grain of salt.

85.560%

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560

segment bisector

step-by-step explanation:

line segment bisector. definition: a line, ray or segment which cuts another line segment into two equal parts. try this drag one of the orange dots at a or b and note the the line ab always divides the line pq into two equal parts.
