C= -3 and d=15
I took the 'c' term out of the left side
c multiplied by 4x makes -12x so c must be -3
that means that -3 multiplied by -5 equals d (which is 15)
Answer:
it would be 2
Step-by-step explanation:
what you do to find the probability is to divide so you divide 60 from 12 which automatically = 5 so then you divide 10 from 5 which gives you 2
The two numbers are 6 and 3
If 3c+4d=2 then c=(2-4d)/3
And if you put that into the other equation
Then you multiply everything by 3, getting
And then
Leaving
I dont have a calc with me right now but you just pot this into the calculator:
And when you get the number you insert it into the nest eqation to get c
So basically
Answer:
H0 : μ1 = μ2
H0 : μ1 < μ2
Step-by-step explanation:
Given :
Early studiers, group 1, mean μ1
Late studiers, group 2 ; mean, μ2
To test the claim that students who study earlier have an average score that is less than the average score for students
The null hypothesis ; there is no difference in average score
H0 : μ1 = μ2
Alternative hypothesis is early studiers means is less than average score of late studiers
H0 : μ1 < μ2
