Answer:
a<-7/2 or a>1
Step-by-step explanation:
2a+5<-2 or -4a-1<-5
2a<-2-5 -4a<-5+1
2a<-7. -4a<-4
2a/2<-7/2 -4a/-4<-4/-4
a<-7/2 a>1
So, here you have to look at the periodic table and see what the molar mass of each molecule composing the water compound

its two hydrogen atom plus an oxygen molecule, making it about 18g per mol.
That said, looking at the mass, we have to ask ourselves, if a mol of water contains 18g of mass, how many moles do we have in 0.5g of water?
We just do a cross multiplication:
Answer:
$38
Step-by-step explanation:
cost of ticket for adult = $22
cost of ticket for youngster = $16
______________________________
cost of ticket for John's mom = $22 as she is adult
cost of ticket for john = $16 as he is young , his age is less than 18 years
Total cost of ticket for John and his mother = $22 + $16 = $38
Rime: A number with exactly two factors; one and itself. What does this mean? This means that for us to call a number prime, only two whole numbers can divide into it without a remainder. Here are a few examples: 2, 3, 5, 7, 11<span>, </span>13<span>, </span>17<span>, </span>19<span>, </span>23<span>, and so on.</span>
Answer:
Residual = 11.462
Since the residual is positive, it means it is above the regression line.
Step-by-step explanation:
The residual is simply the difference between the observed y-value which is gotten from the scatter plot and the predicted y-value which is gotten from regression equation line.
The predicted y-value is given as 20.7°
The regression equation for temperature change is given as;
y^ = 9.1 + 0.6h
h is the observed amount of humidity and it's given to be 23 percent or 0.23.
Thus;
y^ = 9.1 + 0.6(0.23)
y^ = 9.238
Thus:
Residual = 20.7 - 9.238
Residual = 11.462
Since the residual is positive, it means it is above the regression line.
