Circle Q is centered at the origin and has a radius of 9 units. which equation could represent circle Q
Answers
Answer:
x^2 + y^2 = 81
Step-by-step explanation:
Mathematically, the equation of a circle can be represented by ;
(x-h)^2 + (y-k)^2 = r^2
where (h,k) is the center of the circle which is the origin in this case. The origin has the coordinates (0,0)
the radius here is 9 units
Thus, the equation of the circle would be;
(x-0)^2 + (y-0)^2 = 9^2
= x^2 + y^2 = 81

For a hypothesis test of H0: p = 0.35 against the alternative Ha: p > 0.35, the z test statistic is found to be 2.45. What can be said about this finding?
A. The finding is significant at α = 0.05, but not at α = 0.01.
B. The finding is significant at α = 0.01, but not at α = 0.05.
C. The finding is significant at both α = 0.05 and α = 0.01.
D. The finding is not significant at α = 0.05 and α = 0.01.
Answers
Answer:
C
Step-by-step explanation:
Is is a one-tailed test
P(z < 2.45) = 0.9929
1 - 0.9929 = 0.0071
Significant at both 0.05 and 0.01 because both are greater than 0.0071
Answer:
The finding is significant at both α = 0.05 and α = 0.01.

Does the equation y = x/2
represent a proportional relationship?
Yes, because the coefficient of x is positive
No, because it is not in the form y=kx
No, because its graph does not pass through the origin
Yes, because its graph is a line that passes through the origin
QUICK PLEASE!! TY!
Answers
Answer:
D) Yes, because its graph is a line that passes through the origin--------------------------
The form of the equation of a proportional relation is:
y = kx, where k is the coefficient.In the given case y = 1/2x, where k = 1/2, so it represents proportional relationship.
Answer choices:
A. Yes, because the coefficient of x is positive.
False, as the coefficient of x can be negative too.B. No, because it is not in the form y = kx.
False, as it is in the form of y = kx.C. No, because its graph does not pass through the origin.
False, graph passes through the origin.D. Yes, because its graph is a line that passes through the origin
True, the graph passes through the origin; y = 0 at x = 0 regardless the value of k.Describe an event that involves dice and has a theoretical probability of 5\6.

Answers
Answer:
1. Given
2. Addition property of inequality
3. Division property of inequality
4. Square root property
Step-by-step explanation:
The first equation is always going to be the given since it hasn't been solved yet, on the next step you had to get rid of the 1 so you had to add 1 to both sides, this is called addition property of inequality, then to isolate the x you had to divide both sides by 4, this is called division property of inequality and lastly you had to do the opposite of squaring a number, which is taking the square root.

How many times larger is the volume of a cone if the radius is multiplied by 6?
Answers
Answer:
36 times larger.
Step-by-step explanation:
V= [tex]\pi *r^{2}*\frac{h}{3}[/tex] is the original volume of a cone formula.
If the radius is multiplied by 6 the new formula is:
V= [tex]\pi *(6x)^{2} * \frac{4}{3}[/tex]
Which is simplified to:
V= [tex]\pi *36r^2*\frac{h}{3}[/tex]
The only difference between the simplified formula and the original is the *36 so the new volume is 36 times larger when the radius is multiplied by 6.

The line plot shows the number of bags of grapes,grouped by weight, to the nearest 1/8 pound. How many bags of grapes had a weight of 3/8 pound or less
Answers
Answer:
2.25 pounds
Step-by-step explanation:
The diagram showing the weight of bags with grapes is shown in the attached file below.
From the diagram; number of bags of grapes that had a weight of [tex]\dfrac{3}{8}[/tex] pounds or less is:
[tex]\dfrac{3}{8}[/tex] pounds = 3
[tex]\dfrac{1}{4}[/tex] pounds = 4
[tex]\dfrac{1}{8}[/tex] pounds = 1
Thus; the total is = 3+4+1 = 8
However, The total weight of the grapes in the bag that had a weight of [tex]\dfrac{3}{8}[/tex] pounds or less is :
= [tex]\dfrac{3}{8}(3) + \dfrac{1}{4}(4) + \dfrac{1}{8}(1)[/tex]
= [tex]\dfrac{9}{8} + 1 + \dfrac{1}{8}[/tex]
= [tex]\dfrac{9+8+1}{8}[/tex]
= [tex]\dfrac{18}{8}[/tex]
= 2.25 pounds

Find the area of the shaded segment of the circle.
Answers
Answer:
The shaded segment = The arc area - The triangle
The arc area = pi x radius^2 x angle/360
= pi x 9^2 x (360-270)/360 = 63.61 (m2)
The triangle area = 9 x 9/2 = 41.5 (m2)
(because this is right triangle)
=> The shaded segment = 63.61 - 41.5 = 22.11 (m2)

Write the equation of a line that passes through the origin and is perpendicular to the line whose equation is 12x - 4y = 24.
Answers
Answer:
y=-1/3x
Step-by-step explanation:
Let's convert this to slope intercept form:
12x-4y=24
-4y=-12x+24
y=3x-6
Therefore, the slope of this line is 3, so the perpendicular line to this would have slope -1/3. Therefore, the slope of the line would be y=-1/3x. Hope this helps!
A lawn sprinkler located at the corner of a yard is set to rotate 50 degrees and project water out 30.0 feet. To the nearest tenth of a foot, what area of the lawn is watered by the sprinkler
Answers
Answer:
Area of the lawn is watered by the sprinkler is 392.75 ft²
Step-by-step explanation:
As the lawn sprinkler rotate 50 degrees when it project water out, it makes an arc from the corner where it is located.
The area of the lawn in which the water sprinkles, forms a sector with an angle of 50 degrees and radius of 30.0 feet.
[tex]Area \ of \ sector = Area \ of \ lawn= \frac{\theta}{360} \pi r^2\\\\ Area \ of \ lawn= \frac{50}{360} \pi (30)^2 = 392.75 \ ft^2[/tex]
Therefore, area of the lawn is watered by the sprinkler is 392.75 ft²
