PLEASE HURRY Quadilateral abcd is inscribed in circle z such that AB is parallel to DC and m
Answer:
41°
Step-by-step explanation:
Looking at the attached diagram
A central angle of a circle is always congruent to its intercepted arc.
Therefore, m arc BC = m∠BZC
Again, m∠BAC is one-half m arc BC, as the measure of an inscribed angle is half the measure of its intercepted arc.
This gives us the following results:
= m∠BZC = 82°
= m arc BC = m∠BZC
= m arc BC = 82°
= m∠BAC = 1/2 × 82°
= m∠BAC = 41°
Note that:
∠DCA ≅ ∠BAC because alternate interior angles are congruent.
So m∠DCA = m∠BAC.
Hence, m∠DCA = 41°.
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
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.

Given the parent function of f(x) = x^(4, what change will occurr when the function is changed to f((1)/(2) x))
Answer:
The graph of the function f( (1/2)x ) will expand across x-axis
Step-by-step explanation:
We have been given the function:
f(x) = x⁴
If we substitute x = (1/2)x into the given equation, we get:
f((1/2)x) = ( (1/2)x )⁴
We can simplify the equation
f((1/2)x) = = (1/2)⁴ x⁴
f((1/2)x) = = (1/16) x⁴
Graph of both of the functions is shown below. We can clearly see that that the graph of the function f((1/2)x) = = (1/16) x⁴ expands horizontally on x-axis as compared to the graph of f(x) = x⁴

Answer:
A. x = -4
Step-by-step explanation:
We are given the equation:

x - 5 + 5 = -9 + 5
x = -4
The answer is thus A.

2) The volume of water in swimming pools in a local neighborhood are normally distributed. What is the percentage of
volumes that are within 3 standard deviation of the mean?
Answer:
The percentage of volumes that are within 3 standard deviation of the mean is 99.73%.
Step-by-step explanation:
We want to calculate the area under the curve within 3 standard deviations from the mean.
If we use the standard normal distribution, this probability can be calculated as the diference between P(z<3) and P(z<-3).
[tex]P(-3<X<3)=P(z<3)-P(z<-3)\\\\P(-3<X<3)=0.9987-0.0013=0.9973[/tex]
The area under the curve for the standard distribution and for any normal distribution within 3 standard deviation from the mean is 0.9973.
The percentage of volumes that are within 3 standard deviation of the mean is 99.73%.

Answer: Ok for the second one because I don't really get the wording in the first one (thats cuz i SUCK at vocabulary) the answer is 756,100 and a number greater is any number from 756,073-756,149
Step-by-step explanation:
ok so 756072 rounds to 756100 because 72 is closer to 100 than it is to 0
from 50 on, you would round up so to round up to 756100 the smallest possible number is 756050 since the 50 will round up
the highest number is 756149 because from 50 onwards it will round to 756200 instead.
so you can choose any number from 756050-756149
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)

0 4x - y = -6
O x + 4y = 7
Ox - 4y = -9
O 4x + y = 2
Answer:
The answer is x + 4y = 7
Equation of a line is y = mx + c
Where m is the slope
c is the y intercept
Slope of the line between the points
(-1, 2) and (3, 1) is
Slope = 1-2/ 3+1 = - 1/4
Equation of the line using point
(-1, 2) is
y - 2 = -1/4(x + 1)
4y - 8 = - x - 1
x + 4y = 7

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
