Answer:
Step-by-step explanation:
Assuming this is a linear equation in the form of 
, we can first solve for the slope using 
, for these points, the slope would be 
. Now we plug in the points to get the equation:
plugging in (7,5), we get 
×
+ 
and solving for b, we get b = 
therefore, the equation of the line passing through (7,5) and (1,2) is .
hope this helps!
The equation that represents the amount saved by Alyssa after tt weeks is AA = 100 + $7tt
The equation that represents the amount saved by Colton after tt weeks is CC = $55 + $10tt
The amount they would have when they have same amount of money is $205.
<h3>What equation represents the total amount saved?</h3>
The total amount saved: inital amount + (amount saved per week x total number of weeks
AA = 100 + $7tt
CC = $55 + $10tt
<h3>What would be the amount when they have the same amount of money?</h3>
$55 + $10tt = 100 + $7tt
Combine similar terms and solve for tt
100 - 55 = 10tt - 7tt
45 = 3tt
tt = 15 weeks
100 + $7(15) = $205

Answer:
C
Step-by-step explanation:
Finding the z-score:
z = (x - μ) / σ
z = (66 - 57) / 9
z = 1
Using a z-score table or calculator:
P(z < 1) = 0.8413
84.13% of 4000 is:
0.8413 (4000) = 3365.2
Rounding up to the nearest whole number, approximately 3366 students will score less than 66. Answer C.
