Answer:
Step-by-step explanation:
If a third drop out, Initial fraction of those who graduate = 
Three-fifths of those who dropped out(one third) eventually return = 
The proportion of students entering high school who eventually graduate
= Those who graduated Initially+Those who returned
=
Answer:
(1). 8
(2). 8
(3). 8
(4). 8
Step-by-step explanation:
Statement (1).
The domain of this graph is [0, 10]
True.
(x-values or input values of the function is a set of values between 0 and 10 including 0 and 10 both)
Statement (2).
The Range of this graph is {3, 7, 9, 12}.
True.
(For input values x = 0, 4, 9, 10 there is a distinct output value y = 3, 7, 9, 10
Statement (3).
This graph represents continuous data.
True.
Since this graph has a distinct value of y for every value of x and the graph is not interrupted.
Therefore, it's a continuous function.
Statement (4).
The graph represents a function.
True.
For every value of x (input value ) a distinct value of y (output value) is obtained.
Therefore, graph represents a function.
Problem 5
d = 29 = diameter
r = d/2 = 29/2 = 14.5 = radius
SA = surface area of sphere
SA = 4*pi*r^2
SA = 4*pi*(14.5)^2
SA = 841pi
SA = 841*3.14
SA = 2,640.74 square inches
To convert from square inches to square feet, we divide by 144. This is because 12^2 = 144.
2,640.74 square inches = (2,640.74)/144 = 18.3 sq ft
<h3>Answer:
18.3 square feet (approximate)</h3>
=====================================
Problem 6
d = 10.7 = diameter
r = d/2 = 10.7/2 = 5.35 = radius
L = 22.3 = slant height
SA = surface area of the cone
SA = pi*r^2 + pi*r*L
SA = pi*(5.35)^2 + pi*5.35*22.3
SA = 147.9275pi
SA = 147.9275*3.14
SA = 464.49235
<h3>Answer:
464.49235 square cm (approximate)</h3>
The slope-intercept form:
y = mx + b
m - slope
b - y-intercept
We have the line y = 2x - 5.
The parallel lines have the same slope. Therefore we have y = 2x + b.
Put the coordinates of the point B(8, 6) to the equation:
6 = 2(8) + b
6 = 16 + b <em>subtract 16 from both sides</em>
-10 = b → b = -10
The equation of a line: y = 2x - 10.
Put the coordinates of the point A(n, 4) to the equation:
4 = 2(n) - 10 <em>add 10 to both sides</em>
14 = 2n <em>divide both sides by 2</em>
<h3>7 = n → n = 7</h3>
