Plot (−134,412) on the coordinate plane.
We are given coordinate (-1 3/4, 4 1/2).
(-1 3/4, 4 1/2) represents x-coordinate -1 3/4.
And y-coordinate 4 1/2.
First we need to go -1 and three fourth between -1 and -2.
And then for 4 1/2, we need to got 4 above on y-axis and then a half between 4 and 5.
We would draw the coordinate of intersection of vertical line of point -1 3/4 and horizontal line at 4 1/2.
The shown green point on the graph is the coordinate (-1 3/4, 4 1/2).Answer:
I hope this helps! <3
Step-by-step explanation:
Pollsters are concerned about declining levels of cooperation among persons contacted in surveys. a pollster contacts 90 people in the 18-21 age bracket and finds that 76 of them respond and 14 refuse to respond. when 297 people in the 22-29 age bracket are contacted, 262 respond and 35 refuse to respond. assume that 1 of the 387 people is randomly selected. find the probability of getting someone in the 18-21 age bracket or someone who agreed to respond. report the answer as a percent rounded to one decimal place accuracy. you need not enter the "%" symbol. prob = 23.3 incorrect%

Can someone check my answer please?
Quadrilateral ABCD is inscribed in circle O.
What is m∠B?
m∠A + m∠B = 180°
2x - 7 + 2x + 3 = 180
4x - 4 = 180
4x = 184
x = 46
m∠B = 2x + 3
m∠B = 2(46) + 3
m∠B = 92 + 3
m∠B = 95°

what is the sum or difference 10y^10-14y^10
Answer:
The required solution is [tex]-4y^{10}[/tex].
Step-by-step explanation:
The given expression is
[tex]10y^{10}-14y^{10}[/tex]
Take out the common factor [tex]y^{10}[/tex] from both terms.
[tex]y^{10}(10-14)[/tex]
[tex]y^{10}(-4)[/tex]
[tex]-4y^{10}[/tex]
Therefore the required solution is [tex]-4y^{10}[/tex].

What is the ratio for the volumes of two similar cylinders, given that the ratio of their heights and radii is 3:7?
Answer:
The ratio is [tex]\frac{27}{343}[/tex] or 27:343
Step-by-step explanation:
The volume of cylinder is = [tex]V=\pi r^{2} h[/tex] ; where r is radius and h is height.
Given that the ratio of the heights and radii of two similar cylinders is 3 : 7.
Let r' be the radius and h' be the height of the other cylinder.
Its volume is [tex]V'=\pi r'^{2} h'[/tex]
According to the given information, we have
[tex]\frac{r}{r'}=\frac{h}{h'}=\frac{3}{7}[/tex]
Hence, we get
[tex]\frac{V}{V'}=\frac{\pi r^2h}{\pi r'^2h'}[/tex]
= [tex](\frac{3}{7})^{2} \times \frac{3}{7}[/tex]
= [tex]\frac{27}{343}[/tex]
Therefore, the ratio is 27:343

Circle Y is shown. What is the area of the shaded part of the circle?
This question will employ the use of the formula for the area, A, of a sector of any circle. The formula is as:
[tex] A=\frac{\theta}{360^{\circ}}\times \pi r^2 [/tex]
Where [tex] \theta [/tex] is the angle subtended by the required sector. In our case, the sector is the shaded region and we need to find the angle of that shaded region. We know that the total angle of a circle is 360 degrees and the unshaded region subtends an angle of 75 degrees. Thus, the value of [tex] \theta [/tex] is calculated to be:
[tex] \theta=360^{\circ}-75^{\circ}=285^{\circ} [/tex]
r is the radius of the circle which in our case is 9 cm.
Thus, the area of the shaded region is:
[tex] A=\frac{285}{360}\times \pi\times 9^2=\frac{19}{24}\pi\times 81 =\frac{19\times 81}{24}\pi [/tex]
[tex] \therefore A=\frac{19\times 27}{8}\pi=\frac{x}{y} =\frac{513}{8}\pi [/tex] cm^2
Thus, Option D is the correct option.

The cost of producing hard drives has three parts: cost of materials, cost of labor, and cost of equipment. To produce x hard drives, the cost of materials is 30x dollars and the cost of labor is 10x cents. The cost of equipment is a one-time, fixed amount of $10,000. Which equation could represent the cost function for making x hard drives? Answer Choices f(x)=10,030.1x f(x)=10,000x+40 f(x)=30.1x+10,000 f(x)=40x−10,000

Suppose you roll a special 49-sided die. what is the probability that the number rolled is a "1" or a "2"?
Final answer:
The probability of rolling a "1" or a "2" on a 49-sided die is found by adding the separate probabilities of each event, resulting in 2/49 or approximately 0.04082.
Explanation:
In probability, when you want to find the chance of one event or another occurring, you add the probabilities of each event if they cannot happen at the same time. Given a special 49-sided die, each outcome is equally likely, and every roll is an independent event. Therefore, the probability of rolling a "1" is 1 out of 49, and the probability of rolling a "2" is also 1 out of 49. To find the combined probability of rolling either a "1" or a "2", you simply add these two probabilities together.
The probability of rolling a "1" is 1/49, and the probability of rolling a "2" is 1/49. So, the combined probability (P) is:
P("1" or "2") = P("1") + P("2") = 1/49 + 1/49 = 2/49 or approximately 0.04082.

What is the value of n?
Enter your answer in the box.
n = cm
Answer:
n = 14 cm
Step-by-step explanation:
We are required to find the find the value of n.
Since, we have the lines are intersecting in the circle.
So, using the 'Intersecting Chord Theorem', which states that the product of the line segment formed by the intersecting lines are equal.
[tex]4\times n= 8\times 7[/tex]
i.e. [tex]4n=56[/tex]
i.e. n = [tex]\frac{56}{4}[/tex]
i.e. n = 14
Hence, the value of n is 14 cm.
