What point is a solution to the inequality shown in this graph
Answer: A
Step-by-step explanation:
The solution to the graph of inequality given above is the shaded portion or the shaded part of the graph.
Since the point ( -3, -3) and ( 3, -1 ) are on the point line, and the line is a broken line, the inequality means greater than. That means that solution must be greater than those point. They are therefore not part of the solution.
Point ( 5, -5), where x = 5 and y = -5, according to the graph, the shaded portion does not cover y at -5.
Option C is therefore the correct answer which is within the shaded portion. (1, 5)

In OD, AB = CB and marc CE - 52. Find mZBCE. (See picture)
Answer:
A. 109
Step-by-step explanation:
We know that since AB = CB, then ΔABC is isosceles.
Since AC, one of the sides of ΔABC, is on the diameter of circle D, by definition, we know that ΔABC is also a right triangle. Thus, if ΔABC is an isosceles right triangle, then ∠BAC = ∠BCA = 45°.
Draw a line connecting D to B so that we now have isosceles triangle BDC. Since arc BC is 52°, by definition of central angles, ∠BDC is also equal to 52°. Then, ∠DBC = ∠DCB = (180 - 52)/2 = 64°.
∠BCE = ∠DCB + ∠BCA
∠BCE = 64 + 45 = 109°
The answer is thus A.

Which distribution is positively skewed?
Answer:
D
Step-by-step explanation:
not positive but i think it would be D
Option C is the distributions are positively skewed.
Since, A distribution that is positively skewed would have the following highlights:
More points on the left, if represented on a dot plot
Tall bars on the left, if represented on a histogram
Whisker on the left, if represented on a box plot
The above means that none of the distributions are positively skewed.
This is so because:
A is negatively skewed because the whisker is at the right
B and C are symmetrical because there are tall bars at the middle
D is positively skewed because the whisker is at the left.
Hence, Option D is the distributions are positively skewed.

One line passes through the points (−3,−1) and (1,−9). Another line passes through points (1,4) and (5,6). Are the lines parallel, perpendicular, or neither?
Answer:
the lines are perpendicular
Step-by-step explanation:
the first step to this question will be to find the slope intercept form of each of these lines. to do this we will first:
find the slope-
(-3,-1) and (1,-9)
y2-y1 / x2- x1
-9 - (-1) / 1 - (-3) (negative - negative = positive)
-8 / 4
therefore the slope is:
-2
we know that slope intercept form is y=mx+b
so.. y= -2x +______
I left the last part blank, because we only have the first half of the equation, now we will substitute the value of x and y into the equation from one of the coordinate points given above.
(-9) = -2(1) + _____
now we can simplify:
-9 = -2
this equation (-9 = -2) is not true, therefore we need to determine what we have to do to -2 to make it equal to -9.
-9 = -2 - 7 is true
therefore the answer is :
y= -2x-7
therefore the slope intercept form is y= -2x - 7
now that you know how to find the slope intercept form, you can find the other slope intercept form, and i'll provide the answer:
the slope intercept form you should find is
y= [tex]\frac{1}{2}[/tex]x + [tex]\frac{7}{2}[/tex]
now when we plot both of these lines we can see that:
the lines are perpendicular, meaning the lines pass through each other.
Answer:
the two lines are perpendicular to one another
Step-by-step explanation:
Find the slopes of the two lines and then compare them.
If the slopes are the same, the lines are parallel.
If the slopes are negative reciprocals, the lines are perpendicular.
If neither of these conditions hold, then the lines are neither parallel nor perpendicular.
(−3,−1) and (1,−9): As we go from the first point to the second, x (the "run") increases by 4 and y (the "rise") decreases by 8. Thus, the slope of the line through (−3,−1) and (1,−9) is m = rise / run = -8/4, or m = -2.
(1,4) and (5,6): As we go from the first to the second, x increeases by 4 and y increases by 2. Thus, the slope of the line through (1,4) and (5,6) is
m = rise / run = 2/4 = 1/2.
Because 1/2 is the negative reciprocal of -2, we know that the two lines are perpendicular to one another.

A trader claims that the proportion of stocks that offer dividends is different from 0.14. If the trader wants to conduct a hypothesis test, should they use a left-, right-, or two-tailed hypothesis test to analyze whether the proportion of stocks that offer dividends is different from 0.14? Select the correct answer below: Left-tailed test Right-tailed test Two-tailed test
Answer:
The correct option is;
Two-tailed test
Step-by-step explanation:
From the interpretation of the question statement, the trader wants to conduct a hypothesis test on the trader's claim that the proportion of stocks that offer dividends is different from 0.14
Given that the difference is hypothesized, then the null hypothesis, H₀ and the alternative hypothesis, H₁ should be written as follows;
H₀: Null hypothesis (no difference, or no change)
H₁: μ ≠ μ₀ which is hypothesizing difference which is known as a two-tailed test
The confidence level is then selected and the test statistic is calculated
Three congruent isosceles triangles $DAO$, $AOB$ and $OBC$ have $AD=AO=OB=BC=10$ and $AB=DO=OC=12$. These triangles are arranged to form trapezoid $ABCD$, as shown. Point $P$ is on side $AB$ so that $OP$ is perpendicular to $AB$.
Point $X$ is the midpoint of $AD$ and point $Y$ is the midpoint of $BC$. When $X$ and $Y$ are joined, the trapezoid is divided into two smaller trapezoids. The ratio of the area of trapezoid $ABYX$ to the area of trapezoid $XYCD$ in simplified form is $p:q$. Find $p+q$.
Answer:
p+q = 12
Step-by-step explanation:
Let's draw the diagram obtained from the given information. Find attached the diagram.
When X and Y divides the line AD and line BY into half respectively, the diagram splits into two trapezoid.
See attachment for diagram.
Ratio of area ABYX to XYCD = p:q
p+q = ?
Area of trapezoid = ½(base 1 + base 2)height
For trapezoid ABYX:
Base 1 = AB = 12, Base 2 = XY
Using Pythagoras theorem to find height of ∆AOB
AO² = AP² + PO²
PO² = (10²-6²) = (100-36)
PO = √64 = 8
height of trapezoid ABYX =h = ½ PO
= 8÷2 = 4
base of triangles in trapezoid ABYX:
base² = 5² -4² = (25-16)
base = √9 = 3
XY = 12+3+3 = 18
Area of trapezoid ABYX = ½(AB + XY)height
= ½(12+18)×4
= ½(120) = 60
Area of trapezoid XYDC = ½(XY + DC)height
Height of both trapezoid = ½ PO = 4
base of triangles in trapezoid XYCD = 3
DC = 3+18+3 = 24
= ½(18+24)×4
= ½(168) = 84
Ratio of both areas
p:q = 60: 84
p:q = 5:7
p+q = 5+7
p+q = 12

Consider the graph of the linear function h(x) = –6 + h(x) equals negative 6 plus StartFraction 2 Over 3 EndFraction x. x. Which quadrant will the graph not go through and why?
Answer:
2nd quadrant.
Step-by-step explanation:
The given function is
[tex]h(x)=-6+\dfrac{2}{3}x[/tex]
We need to find the quadrant from which the graph of function is not passing.
At x=0,
[tex]h(0)=-6+\dfrac{2}{3}(0)=-6[/tex]
So, y-intercept is (0,-6).
At h(x)=0,
[tex]0=-6+\dfrac{2}{3}x[/tex]
[tex]6=\dfrac{2}{3}x[/tex]
[tex]18=2x[/tex]
[tex]9=x[/tex]
So, x-intercept is (9,0).
It means the graph intersect negative side of y-axis and positive side of x-axis. When we join these two points, we get the graph is not passing through the 2nd quadrant.
Therefore, the required quadrant is 2nd quadrant.

Determine the slope of the lines parallel and perpendicular to -4x+3y=11
Answer:
parallel = 4/3
perpendicular =-3/4
Step-by-step explanation:
Solve for y
-4x+3y=11
Add 4x to each side
3y = 4x+11
Divide by 3
y = 4/3 x +11/3
This is in the form y = mx+b where m is the slope
m =4/3
The parallel line has the same slope
parallel slope is 4/3
The perpendicular line has a negative reciprocal slope
m = -(1 /4/3) = - 3/4
Answer:
[tex]\frac{4}{3}[/tex] and - [tex]\frac{3}{4}[/tex]
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
- 4x + 3y = 11 ( add 4x to both sides )
3y = 4x + 11 ( divide all terms by 3 )
y = [tex]\frac{4}{3}[/tex] x + [tex]\frac{11}{3}[/tex] ← in slope- intercept form
with slope m = [tex]\frac{4}{3}[/tex]
Parallel lines have equal slopes, thus
slope of parallel line = [tex]\frac{4}{3}[/tex]
Give a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{4}{3} }[/tex] = - [tex]\frac{3}{4}[/tex]
