A random sample of 9th-grade students was asked if they prefer taking notes on a computer or using a paper and pencil. Of the 180 students who were surveyed, 75 said they preferred using the computer. The resulting 99% confidence interval for the proportion of students who prefer taking notes on the computer was (0.322, 0.511). The school newspaper ran a story saying that less than half of the student body prefers taking notes on a computer. Based on the interval, is the newspaper justified in this statement?
Answer:
NO
Step-by-step explanation:
since the interval contains values above 0.5, it is plausible that more that 50% of students prefer using a computer for notes.
Using the given confidence interval, since it's upper bound is above 50%, the newspaper is not justified in this statement.
What is the interpretation of a x% confidence interval?It means that we are x% confident that the population parameter(mean/proportion/standard deviation) is between a and b.
Hence, in this problem, we are 99% confident that the proportion is between 0.322 and 0.511. Since the upper bound of the interval is above 50%, there is not enough evidence to say that the proportion is below 50%, hence the newspaper is not justified in this statement.

Step-by-step explanation:
Again, we have to rotate to make the shape fit in, right?
But it wouldn't fit... Or will it? If you can take 2 guesses, you can try the rotation and a translation or the rotation.

Answer:
(a) Reflection and rotation
Step-by-step explanation:
The order of the vertices in the original polygon CDEF is clockwise. The order of vertices in the image polygon GEIH is counterclockwise. This means a reflection is involved in the transformation. Rotation with or without translation will not reverse the orientation.
The only choice that includes reflection is ...
A reflection and a rotation
__
A reflection alone cannot do the transformation shown. A reflection together with rotation and/or translation will do it. For example, reflection across the y-axis, and 90° counterclockwise rotation about the point F'. Or, reflection across the line y=-x and translation right 3 and down 1.

A company makes wax candles in the shape of a cylinder. Each candle has a diameter of 6 centimetres and a height of 2 centimetres. How much wax will the company need to make 270 candles?
Use 3.14 for π, and do not round your answer.
Answer:
270 = 15,268.14030 in³
Step-by-step explanation:
A company makes wax candles in the shape of a cylinder. Each candle has a diameter of 6 inches and a height of 2 inches. How much wax will the company need to make 270 (use 3.14 for n, and do not round your answer)?
Volume = π r² h __ 3.14 * 9 * 2 = 56.52 in³ * 270 = 15,260.4 in³
Using a typical ten digit calculator
3.141592654 * 9 * 2 = 56.54866777 in³ * 270 = 15,268.14030 in³ (rounded)
Volume of cylinder = pi x r^2 x height
Volume = 3.14 x 3^2 x 2 = 56.52 cubic cm.
Multiply the volume of a cylinder by total candles:
56.52 x 270 = 15,260.4 cubic cm

What is the equation of the line that passes through the point (-3, 1) and has a
slope of -2?
Answer:
y = -2x - 5
Step-by-step explanation:
x1 = -3 , y1 = 1 ; m = -2
point slope form : y - y1 = m(x -x1)
y - 1 = -2(x - [-3])
y - 1 = -2(x + 3)
y - 1 = -2x + 3*(-2)
y - 1 = -2x - 6
y = -2x - 6 + 1
y = -2x - 5
