Nkechi wants to use a one-sample z interval to estimate what proportion of candies in a bag are red. She takes a random sample of 24 of the 80 total candies and finds that 18 of the candies in the sample are red. Which conditions for constructing this confidence interval did Nkechi's sample meet? Choose all answers that apply
Answer: The data is a random sample from the population of interest.
Step-by-step explanation: The condition is met since she randomly selected the sample from the population of interest.
The data is a random sample from the population of interests.(Option A), and individual observations can be considered independent.(Option C)
What are the conditions for valid inference about one proportion?Random sample: The sample should be taken randomly.Normal distribution of proportion: The sampling distribution of the proportion we're taking about should be normally distributed.Independent observations: Each of the observations must be independent.The missing options are:
A. The data is a random sample from the population of interests.
B The observed counts of successes and failures are both sufficiently large.
C. Individual observations can be considered independent.
For this case, we're given that the sample was random.
Sample size is 24,which is not sufficiently large (usually we take > 30 as sufficiently large size).
Also, each candle was independent for being red colored.
Thus, the data is a random sample from the population of interests.(Option A), and individual observations can be considered independent.(Option C)

Answer:
The y-int represents the base price of $200 for airfare from NYC
The slope represents a cost of 30 cents per mile traveled
If the base cost for airfare changed to $50 and the cost per mile is unchanged, the new equation would be y=50+0.30x
If the cost per mile changed to 50 cents, the new equation would be y=200+0.50x

The volume of the rectangular prism is 24 inches cube.
What is volume?Volume is the scalar quantity of any object that specified occupied space in 3D.
For example, the space in our room is referred to as volume.
Volume has units of cube example meter³,cm³, etc.
The volume of cuboid = length × height × width.
The volume of the cube = side³.
Given the rectangular prism with a bunch of small cubes whose volume is 1/4 inches³.
Number of small cubes = 8 × 4 × 3 = 96
The volume of the complete prism = Volume of 1 cube × the Number of small cubes.
The volume of the complete prism = 1/4 × 96
The volume of the complete prism = 26 inch³.
Hence "The volume of the rectangular prism is 24 inches cube".

Answer:
5c^2+2cd-2d^2-15
Step-by-step explanation:
Hello, to find the perimeter of any shape, you just add all the side together. In this picture, you would add all the sides up like this:
4c^2+4cd+12+-5d^2-5cd+2+c^2-d^2+1+3cd+4d^2-30
Then, combine like terms (add all of the numbers with the certain variable together) and you would get the answer which is:

Answer:
Volume of box V = 180 cm^3
Base area of box A = 36 cm^2
Height = h
Volume = base area × height
height = volume/base area
h = V/A
Substituting the values;
h = (180cm^3)/(36cm^2)
Height h = 5 cm
