Answer:
Approx 467 students is the answer.
Step-by-step explanation:
Francis surveyed a random sample of 70 students at Franklin High School about their favorite season.
Of the students surveyed, 18 chose fall as their favorite season.
There are 1816 students at Franklin High School.
Now, students chose fall as their favorite season.
This comes to 0.257 percent.
We can say that 0.257 % of 1816 students can like fall season.
= 466.712 ≈ 467 students. (approx)
Therefore, the most reasonable estimate for the number of students at Franklin High School whose favorite season is fall is 467.

Answer:
RT = 12 units
Step-by-step explanation:
From the figure attached,
ΔSRQ is right triangle.
m∠R = 90°
An altitude has been constructed from point T to side SQ.
m∠RTQ = 90°
By applying geometric mean theorem in triangle SRQ,
x² = 16 × 9
x² = 144
x = √144
x = 12
Therefore, length of altitude RT is 12 units.
The coordinates of the 2 given points are W(-5, 2), and X(5, -4).
First, we find the midpoint M using the midpoint formula:
Nex, we find the slope of the line containing M, perpendicular to WX. We know that if m and n are the slopes of 2 parallel lines, then mn=-1.
The slope of WX is
.
Thus, the slope n of the perpendicular line is
.
The equation of the line with slope
containing the point M(0, -1) is given by:
