Answer:
D, A
Step-by-step explanation:
a line segment has two endpoints and a length that is finite or can be measured.
a line goes in both directions infinitely; cannot be measured
a ray has one endpoint and travels in 1 direction infinitely; cannot be measured
Answer:
Step-by-step explanation:
'll just help with proving whether she is correct.
First of all, a fraction divided by a fraction can be made into multiplication since the division of two fractions is kinda difficult
so remember keep, change, flip
keep the first fractions, change the division symbol into multiplication, then flip the fraction i.e. 1/2 becomes 2/1
so 5/2 divided by 1/4 becomes
5/2 * 4/1
which then solved becomes
20/2 which is simplified to 10
Hope this helps :)
I don't understand this question, can you maybe reword it or make it easier to understand? There's no grammar so I can't understand.
This is a binomial distribution where 80% of flights arrive on time (p = 0.8) and 20% do not (q = 1 - 0.8 = 0.2). Then the probability that exactly 2 flights arrive late follows the formula:
(nCr)(p^r)(q^(n-r)), where n = 16 (total # of flights), r = 14 (flights that arrive on time)
(16C14)(0.8^14)(0.2^2) = 0.2111
$200
They first took $100 then came back and bought $70 worth of merchandise and paid with the 100 dollars they stole, in turn you gave them change of 30 dollars. So you are now short $130 in the register and 70 in merchandise for a total of $200.
