In 386750.36 years the Carbon - 14 will be 20 g in the substance
Step-by-step explanation:
Here A = 20 g
The given equation is,
A= 25e - 0.000124t
We need to find the value of t
20 = 25e - 0.000124t
20 - 25e = - 0.000124t
25e - 20 = 0.000124t
(25e - 20 ) / 0.000124 = t
t = (25e - 20) / 0.000124
t = (65.957 - 20) / 0.000124
t = 45.957 / 0.000124
t = 386750.36 years
Answer:
8
Step-by-step explanation:
Recall the formula for the population mean of a data set:
We already know that μ is 6 and the sum is 48. Substitute:
Divide both sides by 48:
Reciprocal of both sides:
Thus, there are 8 scores in the population size.
And we're done!
Answer:
0.5

Answer:
No, they are not equivalent
Step-by-step explanation:
8x + 3(x + y)
8x + 3x + 3y
11x + 3y
7x + 7y + 4x + 4y
11x + 11y
They are not equivalent because in one of the equations, the like terms add up to 11y which is different from the other equation which adds up to 3y.
I hope this helps.
D is the midpoint of A and B
A = (0,s)
B = (r,0)
Add up the x coordinates to get 0+r = r. Then cut that in half to get r/2
Similarly, do the same for the y coordinates: s+0 = s ---> s/2
So the location of point D is (r/2, s/2)
