Subtract the difference from the total, then divide by 2, that would be the age of the youngest, then add the difference to that for the age of the oldest.
37 - 5 = 32
32 / 2 = 16
The youngest is 16.
16 + 5 = 21
The oldest is 21.
The ages are 16 and 21.

Answer:
Answer:
a).
The amount spent on school materials for each term of all ST201students
b).
a).
It is not a random sample. This looks like a convenience sampling and there is sampling bias. This sample is not representative of the entire population. Since it is not a random sample it is not appropriate to generalize the results to all students.
b).
The sample size is 80 which is greater than 30. It is large enough to assume normal distribution according to central limit theorem.
c).
mean: $617
z critical value at 95%: 1.96
standard error = σ/sqrt(n) =500/sqrt(80) = 55.9017
lower limit= mean-1.96*se = 617-1.96*55.9017=507.43
upper limit= mean+1.96*se = 617+1.96*55.9017=726.57
d).
The amount spent on school materials for each term for the 80 ST201students is $617. We are 95% confident that amount spent on school materials for each term of all ST201students falls in the interval ($507.43, $726.57).

Answer:
<h2>y = 2x + 4</h2>
Step-by-step explanation:
The linear functions are the ones that can have at most 1 x-intercept. Specifically, slant lines and vertical lines have this characteristic.
The quadratic function doesn't have this characteristic because there are cases where it intercepts x-axis at two points (concave down).
Additionally, the exponential function doesn't have any x-intercept, because its range is restricted.
Therefore, the right asnwer is the linear function
Answer:
D.
Step-by-step explanation:
I have been doing this in Geometry.
We know perpendicular means opposite recipicoles and opposite slopes.
so.. the slope is 3 to get the y-intercept you do this.
(1, 2) Use the points it gave you and the slope 3 and put it is y=mx + b form
2 = 3(1) + b (I do this because I don't know what b is yet) (b = y-intercept)
2 = 3 + b (subtract 3 on both sides)
-1 = b
The equation is y = 3x - 1
