Answer:The ansewers are c and d.
Step-by-step explanation:
The function f(x)=x is really y=x.
Answer:
Probability is the likelihood or chance of an event occurring. Probability = the number of ways of achieving success. the total number of possible outcomes.
Step-by-step explanation:
Think of it as a chance or the percent of an event happening. Such as it raining on a sunny day would be 15%-0% probability.
Answer:
P (not drawing a black marble) = 4/5
P (red marble) = 3/10
Step-by-step explanation:
The total number of marbles is
5 blue marbles +2 black marbles+ 3 red marbles = 10 marbles
P (not drawing a black marble) =
The marbles that are not black/ total marbles
(blue + red)/ total
(5+3)/10
8/10
4/5
P (red marble) = red marble/ total
= 3/10
Not sure
te rate is r
for decay, it is
A=P(1-r)^t
r=rate
P=present amount
dunno what b is
but I guess
A=28000(1-0.13)^t
A=28000(0.87)^t
I would guess the decay factor would be 0.87
Using proportions, it is found that:
- Each of Brendan and Clair get R 1387.5.
<h3>What is a proportion?</h3>
A proportion is a fraction of total amount.
In this problem, the total amount divided is R 4625.
For every R4 Andrew gets, both Brendan and Clair gets R3, hence the ratio is 4:3:3, which means that:
- Andrew gets
of the total amount.
- Brendan gets
of the total amount.
- Clair gets of the total amount.
Then:
Hence:
- Each of Brendan and Clair get R 1387.5.
