Answer:
A. $46,650
Step-by-step explanation:
Taking the first number of $50,150, we have to subtract his expenses. After subtracting Leroy's expenses, we get $46,650.
50150
<u>- 3500</u>
46650
Answer:
(a) 0.5899
(b) 0.9166
Step-by-step explanation:
Let X be the random variable that represents the height of a woman. Then, X is normally distributed with
= 62.5 in
= 2.2 in
the normal probability density function is given by
, then
(a)
= 0.5899
(in the R statistical programming language) pnorm(63, mean = 62.5, sd = 2.2)
(b) We are seeking
where n = 37.
is normally distributed with mean 62.5 in and standard deviation
. So, the probability density function is given by
, and
= 0.9166
(in the R statistical programming language) pnorm(63, mean = 62.5, sd = 2.2/sqrt(37))
You can use a table from a book to find the probabilities or a programming language like the R statistical programming language.
Answer:
23/2
Step-by-step explanation:
first turn the mixed number into a fraction:
2*10=20
20+3=23
so, we get 23/2
