Answer:
3
Step-by-step explanation:
Standard derivation is how much the data varies from the mean
class 2 has a lower derivation, the scores vary less from the mean, being closer
K= 10(-7) -19
k= -70-19
k=-89
3s + 135 = 4.5s + 45
Now move the variables and coefficients
135 = 1.5s + 45
And then the numbers
90 = 1.5s
Simplify
90/1.5 = 1.5s/1.5
60 = s
Hope this helps!
Answer:
Step-by-step explanation:
95%+15%=110% so, 110%-100% is 10% and this means that 10% of both, costs 1.20. now, 10 times 1.20 is 12 dollars and we know that the whole purchace costs 12 dollars. 15 percent of 12 dollars is 1.8 dollars or, one dollar and 80 cents
