Answer:i believe its 3 correct me if im wrong
Step-by-step explanation:
The Answer is B Because i fu plug it in it works
Answer:
From the General Equation of a straight line
Y=Mx + c
where M = Slope of the line
c= Intercept on Y axis
y=-4.2x-80
Comparing with the Eqn of a straight line
Slope = -4.2
From the Options the answers are in Fractions
You can easily convert this figure to fraction by Moving the decimal to the back once and then divide by 10
Then we have -42/10
Reducing Further
you have = -21/5.
Option D✅
There are 36 outcomes when rolling a pair of dice.
The ones adding up to 8 are: (2,6),(3,5),(4,4),(5,3),(6,2).
So the probability of rolling a sum of 8 is 5/36.
With three (independent) random throws, the probability of having a sum of 8 at least once equals 1-probability of no 8 at all.
P(not 8)=1-5/36=31/36
For this to happen three times, we use the multiplication rule
P(not 8 three times)=(31/36)^3=29791/46656=
Therefore
P(sum of 8 at least once)=1-29791/46656=16865/46656
[=0.3615 approx.]
