Which statement explains whether -4.5 can be a value in the shaded region
A. No it cannot, because -4.5 lies to the right of -3.5
B. No it cannot, because -4.5 lies to the right of -3.5
C. Yes it can, because-4.5 lies to the left of -3.5
D. Yes it can, because -4.5 lies to the right of -4.5
Answer:
Option C is correct option.
Step-by-step explanation:
The option C : Yes it can, because-4.5 lies to the left of -3.5 is the correct option.
Reason:
-4.5 is less than -3.5 and it comes after -4 so it lies under the shaded region.
Option C is correct option.

An electrician has a piece of wire that is 18 feet long. He cuts off 14% of the wire. Then he cuts the remaining pieces of wire into 3 equal pieces. What is the length of each piece.
Answer:
the 3 pieces are 5.16ft each and the 14% that he cut off is 2.52 ft
Step-by-step explanation:
the 14 % that he cut off is 2.52ft
he has 15.48ft left
15.48/3=5.16
What is the equation of the line that passes through the point (-4,-8) and has a slope of 4
Answer:
y=4x+28
Step-by-step explanation:
(y-y1)=m(x-x1)
(y +4) = 4(x+8)
y+4 = 4x+ 32
y=4x + 28

The accompanying data resulted from a flammability study in which specimens of four different fabrics were tested to determine burn times. Fabric Type Ýi. Si ni 1 11.6 .75 42 13.1 .88 43 14.5 .94 44 15.6 .98 4The analysis of variance is given as follows: Source DF SS MS F p-value Fabric Type 3 28.322 9.441 11.875 0.002 Error 12 9.543 0.795 Total 15 37.865 A) Write a linear contrast for Question 1: Is the mean burn time of fabrics of type 3 different than the mean burn time of type 4? B) Write a linear contrast for Question 2: Is the mean burn time of fabrics of type 1 different than the average of burn times of fabrics of the other three types (2, 3, 4)? C) Are the two contrasts defined in (a) and (b) mutually orthogonal? Explain why or why not. D) Conduct a F test about the linear contrast defined in (a). Use a = 0.05
Answer:
Following are the solution to the given point.
Step-by-step explanation:
In point a:
Linear comparison of the mean burning period of textiles of type three different from the mean type 4 burn time:
[tex]\to C_1= \bar{y_3}- \bar{y_4}[/tex]
In point b:
Linear comparison to the moderate burning time of type 1 textiles distinct from the average burn periods of all the other three styles of textiles[2,3,4]: is
[tex]\to C_2 = \bar{y_1} - \frac{1}{3} \bar{Y_2} - \frac{1}{3} \bar{Y_3} - \frac{1}{3} \bar{Y_4}[/tex]
In point c:
The comparison in a and (b) above is orthogonal to one another. Since the number of coefficient products is :
In point d:
The contrast value is [tex]C_1 = \bar{y_3} -\bar{y_4}.[/tex] The estimate of the contrast:
[tex]=14.5-15.6\\\\=-1.1[/tex]
The standard error is
[tex]= \sqrt{0.795 \times \frac{2}{4}}\\\\ = \sqrt{0.3975}\\\\= \sqrt{0.6305}[/tex]
[tex]t= \frac{(\bar{y_3} - \bar{y_4})}{SE(\bar{y_3} - \bar{y_4})}= \frac{-1.1}{0.6305}= -1.7447[/tex]
T is 2.1788 as the critical value. Since the value of t=1.7447<th of the critical value is absolute, the null is not rejected
The hypothetical one. theory. Therefore the impact of contrast is not statistically significant.
As we know t is a test F. Alternatively, as we know. The F-statistics at 1,12 df is [tex]t^2 = -1.7445^2 = 3.0440.[/tex]
F test is critical to 4,7472.

Equation of (y - k)^2 = 4p (x - h), where the focus is (h + p, k) and the directrix is x = h - pGiven is the parabola:
(y + 1)^2 = (x + 2)It has a vertex at (-2, -1)
New vertex (-1, -1) requires translation to the right by 1 unit. Which changes the function to:
(y + 1)^2 = (x + 2 - 1) ⇒ (y + 1)^2 = (x + 1)For this function the focus and directrix is:
(y + 1)^2 = (x + 1)k = -1, p = 1/4, h = -1Focus is
(h +p, k) = (- 0.75, -1)Directrix is:

Find the slope of the line parallel to the given line and the slope of the line perpendicular to the given line (3,5) (2,8)
Answer:
-3
Step-by-step explanation:
(8 - h)(jh + jh) use h=-1 and j=5
I would do this but im kind of confused please help
Answer:
-90
Step-by-step explanation:
(8-h)(jh+jh)
Since the values of h and j are given, we use substitution to replace the variables with their number values
(8-(-1))(j(-1)+j(-1) replaced all the h with -1
(8-(-1))((5)(-1) + (5)(-1)) replaced all the j with 5
Then we solve inside the parenthesis first
(8+1)(-5+(-5))
(9)(-10)
Then, multiply
-90
