Arionna needed to graph triangle PQR reflected across the y-axis. Her work is shown below. Arionna’s Work: Blue right-arrow red. P (3,7) right arrow P prime (3, negative 7). Q (0, 4) right-arrow Q prime (0, 4). R (5, 8) right-arrow R prime (negative 5, 8). Arionna’s Graph On a coordinate plane, a red triangle has points (negative 7, 3), (negative 5, 8), (0, 4). A blue triangle has points (0, 4), (3, 7), (5, 8). Which statements identify her errors? Check all that apply. Arionna did not find the correct point for P’. She should have negated the x-value, not the y-value. Arionna did not find the correct value for Q’. All points in a reflection will move. Arionna did not find the correct value for R’. She should have negated the y-value, not the x-value. Arionna’s red triangle should be reflected below the horizontal axis rather than across the vertical axis. Arionna switched the order of the coordinates of P’ (3, –7) when she graphed them.

What is cartesian plane?A two-dimensional coordinate plane called the cartesian plane is what is created when the x- and y-axes cross. The origin is the place where the x-axis and y-axis meet perpendicularly.
A pair of perpendicular lines connect to create the cartesian plane, a two-dimensional coordinate plane. The term "Y-axis" refers to the vertical line, whereas "X-axis" refers to the horizontal line. The Cartesian coordinate point (x, y) indicates that the point's horizontal and vertical distances from the origin, respectively, are x and y, respectively. If x has a positive sign, the point will be to the right of the origin.
Given, Arionna needed to graph triangle PQR reflected across the y-axis.
Arionna’s Work:
Blue right-arrow red. P (3,7) right arrow P prime (3, negative 7). Q (0, 4) right-arrow Q prime (0, 4). R (5, 8) right-arrow R prime (negative 5, 8).
Reflection across y axis
(x , y) becomes ( - x , y)
P ( 3 , 7) P ' ( 3 , -7) The correct solution should have been ( -3 , 7),
Q ( 0 , 4) Q' ( 0 , 4) This is correct,
R (5 , 8) R' (-5 , 8) This is correct,
Arionna was unable to determine P's proper point. Not the y-value, but the x-value should have been negated instead.
The graph of Arionna
The points of a red triangle on a coordinate plane are (-7, 3), (-5, 8), and (0, 4).
When graphing P"s coordinates (3, -7), Arionna reversed their order.
A blue triangle has points (0, 4), (3, 7), (5, 8).
Hence Arionna Graph is attested in image.

145
Step-by-step explanation:
Each triangular side is 30ft
bottom is a 5*5 so it 25ft
30*4(#of sides)=120
120+25(bottom)=145
Answer:
I will give you the easy explanation here, go down there though to get a more complexed explanation and answer. Seeing it is a triangle, you can not multiply the 12 by 5. You have to multiply it by 2.5 because it dips in (because it's a triangle). Now you multiply the 5x5 to get 25. Now we have 25 for the base and 30 for each side. 30x4 to represent each side and add 25 for the base to get 145 as the final answer.
Step-by-step explanation:
Ok, they made this really easy with the 5's. You multiply the 5 by the 5 to get 25 in which the 12 there is about half of that, that made things really easy. Since the 12 goes to the middle that means that we can take what is from the middle to the side removing the half there getting you -2. Therefore, 12-2=10. Meaning the center is 10.

The distribution of the amount of money spent by students on textbooks in a semester is approximately normal in shape with a mean of: μ = 473 and a standard deviation of: σ = 28. According to the standard deviation rule, almost 0.15% of the students spent more than what amount of money on textbooks in a semester?
Answers
Answer:
0.15% of the students spent more than 557 on textbooks in a semester
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 473
Standard deviation = 28
According to the standard deviation rule, almost 0.15% of the students spent more than what amount of money on textbooks in a semester?
99.7% of the measures are within 3 standard deviations of the mean, so 100 - 99.7% = 0.3% are more than 3 standard deviations from the mean.
The normal distribution is symmetric, which means that 0.3%/2 = 0.15% spend less than 3 standard deviations below the mean, and 0.15% spend more than 3 standard deviations above the mean.
473 + 3*28 = 473 + 84 = 557
0.15% of the students spent more than 557 on textbooks in a semester

The city of Raleigh has 6000 registered voters. There are two candidates for city council in an upcoming election: Brown and Feliz. The day before the election, a telephone poll of 250 randomly selected registered voters was conducted. 100 said they'd vote for Brown, 141 said they'd vote for Feliz, and 9 were undecided. Describe the population actually represented by this survey.
Answers
Answer:
[tex]Brown = 2400[/tex]
[tex]Feliz = 3384[/tex]
[tex]Undecided = 216[/tex]
Step-by-step explanation:
Given
[tex]N = 6000[/tex] -- population
[tex]n = 250[/tex] -- sample
From the sample, the proportions are:
[tex]B = 100[/tex] -- Brown
[tex]F=141[/tex] -- Feliz
[tex]U = 9[/tex] -- undecided
Required
Describe the actual population
The actual is calculated using:
[tex]Actual = \frac{p}{n} * N[/tex]
So, for Brown
[tex]Brown = \frac{100}{250} *6000[/tex]
[tex]Brown = \frac{100*6000}{250}[/tex]
[tex]Brown = \frac{600000}{250}[/tex]
[tex]Brown = 2400[/tex]
For Feliz
[tex]Feliz = \frac{141}{250} * 6000[/tex]
[tex]Feliz = \frac{141* 6000}{250}[/tex]
[tex]Feliz = \frac{846000}{250}[/tex]
[tex]Feliz = 3384[/tex]
For undecided
[tex]Undecided = \frac{9}{250}*6000[/tex]
[tex]Undecided = \frac{9*6000}{250}[/tex]
[tex]Undecided = \frac{54000}{250}[/tex]
[tex]Undecided = 216[/tex]
