gavmur [86]

Answer

given,

mean of women  (μ)=63 inches

standard deviation of women (σ)= 2.4 inches

mean of men (μ)=70 inches

standard deviation of women (σ)= 2.5 inches

for women

P(x>66)

P(x>66) = 1-P( \dfrac{x - \mu}{\sigma}

P(x>66) = 1-P( z

P(x>66) = 1-P( z

using z-table

P(x>66)= 1 - 0.8944

P(x>66)=0.1056[/tex]for men[tex]P(x>66)

P(x>66) = 1-P( \dfrac{x - \mu}{\sigma}

P(x>66) = 1-P( z

P(x>66) = 1-P( z

A grocery store has a shelf with half-gallon containers of milk. What type of number best represents the total number of gallons
Veronika [31]
As a number, half-gallon can be represented as 0.5.
In order to answer this question we will define each term:

whole numbers are numbers that can be defined as a <span>number without fractions which are greater or equal than 0. E.g. 2 0 1 5 6 85
</span>
integer numbers are numbers that can be defined as a number without fractions but which can be either equal to 0 or greater and lower than 0
E.g. -9 -68 8 0 59

rational numbers are  any number that<span> can be expressed as a fraction p/q of two integers E.g. 0.5 = 1/2 1 = 1/1 1.25 = 5/4
</span>
irrational numbers are those which have an approximate value E.g. pi = 3.14...
√2 = 1.41.....

real numbers are all of the above

From all those kind of choices the most accurate representation is rational numbers.
