Step-by-step explanation:
4 marbles we have to take out (without looking) to be sure that we have at least two marbles of the same color.
There are 4 black, 4 red, and 4 white marbles in a box.
So, in order to have atleast two marbles of the same color we must take out atleast four marbles.
That is 1 black, 1 red, and 1 white of each color and the fourth one may be of any color. So we have atleast two marbles of the same color.
Therefore we have to rake out atleast 4 marbles in order to have at least two marbles of the same color.

solve for m
0.2m=3.5
Answer:
m = 17.5
Step-by-step explanation:
Given 0.2m=3.5, we want to solve for m. This involves isolating m on the left side. To accomplish this, divide both sides by 0.2, obtaining:
m = 3.5/0.2, or m = 17.5

A cedar chest is a shaped like a rectangular prism. The cedar chest is 2 feet tall, 4 feet wide, and 2 feet deep What is the surface area of the cedar chest? Enter your answer in the box
Answer:
40 ft^2
Step-by-step explanation:
lateral surface area -Slat = 24 ft^2
top surface area-Stop = 8 ft^2
bottom surface area-Sbot = ft m^2
24+8+8= 40
total surface area-Stot = 40 ft^2
The surface area of a rectangular prism or cedar chest of 2 feet tall, 4 feet wide, and 2 feet deep is 40ft sq.
The length of a rectangular prism is 2 feet.
The width of a rectangular prism is 4 feet.
The height of a rectangular prism is 2 feet.
we need to find the surface area of a rectangular prism.
What is a rectangular prism?
A rectangular prism is a 3-dimensional representation, that has six rectangular faces two at the top and bottom and four are lateral faces. A rectangular prism is also known as a cuboid.
The surface area of a rectangular prism = 2(lb + bh + lh)
So, the surface area of a rectangular prism = 2(lb + bh + lh)
[tex]=2(2\times4+4\times2+2\times2)\\=2(8+8+4)\\=40[/tex]
Hence, the surface area of a rectangular prism or cedar chest is 40ft sq.

by side and then make a rectangular gravel border around the resulting it by 25t
plot. The area of the new garden and border will equal the sum of the areas of the two
original gardens and borders.

Write expressions for the length and width of the plot consisting of the new garden
and its gravel border. Each expression must be a linear polynomial with integer
coefficients. Use your expressions to draw a sketch of the new garden and border.

Answer:
last option: 9200 + 80c ≤ 25,000
Step-by-step explanation:
the options showing ≥ 25,000 cannot be solutions because the weight must be less than 25,000
if there already is 9200 then that would be added to 80c and, when solved, would tell you how many 80kg containers can be loaded
80c ≤ 25,000 - 9,200
80c ≤ 15,800
c ≤ 15,800 ÷ 80
c ≤ 197.5
An experiment to test the effectiveness of regular treatments with fluoride varnish to reduce tooth decay involved 36 volunteers who had half of their teeth (the right side or left side, determined by a coin flip) painted with a fluoride varnish every six month for 5 years. At the end of the treatments, the number of new cavities during the treatment period was compared on treatment (fluoride varnish) side versus the control (no fluoride varnish) side. The appropriate statistical test for analyzing the results of this experiment is
Answer:
One-sample t-test on paired data.
Step-by-step explanation:
Here, two different measures or reading were obtained for the two treatment (fluoride vanish) and the control (no fluoride vanish). However, this two measurement were obtained from each of the observations or subjects, hence why it is called one sample t-test on paired data. This would allow the effectiveness of the floiride vanish treatment on each the subjects teeth as we'll have two different data (fluoride vanish treatment) and control treatment on each the subjects employed for the study.
