How do you explain a diameter of 0.00085 inches using scientific notation
dezoksy [38]

Answer:

8.5 E^{-4} inches

Step-by-step explanation:

        Scientific scientific notation  is where the super small / super large number is multiplied by a 10 (E) to the power of a number. Here, the number is smaller than 8.5 so our power must be negative. As we are making it four "places" bigger, we use the exponent of -4.

Hope this helps, have a nice day! :D

kykrilka [37]

Answer:

X=1, P = 0.091

X=2, P = 0.124

X=3, P = 0.115

X=4, P = 0.378

X=5, P = 0.264

X=6, P = 0.028

Step-by-step explanation:

To calculate the probability distribution of X, first we have to define the sample space.

In this case X=1,2,3,4,5,6. This are the values that X can take.

The probability is calculated as equal to the relative frequency of each of the values.

For X=1, P = 364/4000 = 0.091

For X=2, P = 496/4000 = 0.124

For X=3, P = 460/4000 = 0.115

For X=4, P = 1512/4000 = 0.378

For X=5, P = 1056/4000 = 0.264

For X=6, P = 112/4000 = 0.028
