Given:
The equation of the line of best fit is :
[tex]y=4.722392638x+50.99539877[/tex]
To find:
The x-intercept and check whether it make sense in this context.
Solution:
We have,
[tex]y=4.722392638x+50.99539877[/tex]
Substitute [tex]y=0[/tex] to find the x-intercept of the given best fit line.
[tex]0=4.722392638x+50.99539877[/tex]
[tex]-50.99539877=4.722392638x[/tex]
[tex]-\dfrac{50.99539877}{4.722392638}=x[/tex]
[tex]-10.7986359202=x[/tex]
So, the x-intercept is at point (-10.7986359202,0). It means the score on final examination is 0 if -10.7986359202 hours spent on studying.
But is does not make sense because the number of hours cannot be negative.

what are sides 'a' and 'b' called in a right triangle
Answers
Answer:
The relation between the sides and angles of a right triangle is the basis for trigonometry.
Step-by-step explanation:
The side opposite the right angle is called the hypotenuse (side c in the figure). The sides adjacent to the right angle are called legs (sides a and b ).
Answer:
The legs
Step-by-step explanation:
In a right triangle, sides a and b are called "the legs." These are the sides that create the right angle. Side c is called the hypotenuse and it is the longest side of a right triangle. Side c is opposite of the right angle.

Answer:
y > 4x - 2
Step-by-step explanation:
The basic format of a line in slope-intercept form is,
[tex]y=mx+b[/tex]
This format undergoes no change when one implements it for the use of a two-variable inequality.
The parameter (m) represents the slope of a line, this can be found by using the formula ([tex]\frac{rise}{run}[/tex]). Traditionally, one would use a formula to find the slope of a line that is the following, ([tex]\frac{y_2-y_1}{x_2-x_1}[/tex]). However, in the given situation, one can simply count the number of boxes from one point with respect to the x-axis to another, and thus get (4).
The parameter (b) represents the point in which the graph intersects the y-axis, one can see that this point is (-2).
Since the line is dotted, one would only use the greater than symbol, not the greater than or equal-too-symbol.
Finally, since the area above the line is shaded, therefore one knows that it is (y) is greater than.

If the simple interest on $1,000 for 8 years is $ 480 then what is the interest rate?
Answers
Answer:
6%
Step-by-step explanation:
Given data
Principal = $1,000
Time= 8 years
Simple interest= $480
The expression for the simple interest is
Simple interest= PRT/100
Substitute
480= 1000*R*8/100
Cross multiply
480= 8000R/100
480*100= 8000R
48000= 8000R
Divide both sides by 8000
R= 48000/8000
R=6%

if ax+bx=a^2-b^2 then what is the value of x
Answers
Answer:
Factorise both sides of
ax+bx=a2−b2
and get
(a+b)x=(a+b)(a−b).
If
a+b≠0,
because division by 0 is not allowed, then divide by a + b and get
(a+b)xa+b=(a+b)(a−b)a+b.
It reduces to
x=a−b.
If a+b=0, then
ax+bx=a2−b2 is
(a+b)x=(a+b)(a−b)
and this simplifies to
0x=0(a−b),
that is,
0=0,
so that the value of x is indeterminate.

A door is fixed at the point O. Ben opened it by an angle of 30°. The area swept by the door was {25}{12}\pi\
Answers
Answer:
5 units
Step-by-step explanation:
Area swept by the floor will be the area ofd a sector
Area of a sector = theta/2π * πr²
We are to find the radius r
Given
Area= 25π/12
theta = 30° = π/6
Substitute
25π/12 = 30/360 * πr²
25π/12 = 1/12 * πr²
25/12 = r²/12
r² = 25
r = √25
r = 5
Hence the radius od the part swept by the door is 5 units
