Answer:
a) 0.7
b) 0.3
c) 0
d) 1
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
(a) Coke
Out of 10, 7. So
(b) fanta
3 out of 10. So
(c) neither Coke nor fanta
7 Coke, 3 fanta, so all 10 are either coke or fanta. Thus:
(d) either Coke or fanta
All 10. Thus:
Answer:
y = -(3/7)x + 2
Step-by-step explanation:
(see attached)
recall that the slope-intercept form of a linear equation is
y = mx + b
where m = slope = given as -(3/7)
and b = y-intercept = 2
substituting these values into the eqation:
y = mx + b
y = -(3/7)x + 2
Inverse variation means y=k/x (direct variation is y=kx) so we can use the info given to find the constant k
y=k/x
6=k/900
k=6(900)
k=5400 so the equation is:
y=5400/x or more accurately for this problem
t(v)=5400/v then:
t(800)=5400/800
t(800)=6.75 hours
Answer:
4
Step-by-step explanation:
because the car says which one is more
To get your answer we'll plug 0 in for x into the equation.
So, multiply 4*0 which equals 0.
Then we'll add 0 and 7 which leaves us with
The y-intercept of this equation is: 
To find the x-intercept of this equation we'll rewrite it as
Then we'll subtract 7 from both sides,
Now we'll divide each side by 4. Then simplify which brings us to our answer,
The x-intercept of this equation is:
