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.
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

32.5 pounds of meat for them each day. Each mountain lion receives
the same amount. What equation can you use to find how much meat
each mountain lion eats in a day?
Answer:
y=32.5÷5
Step-by-step explanation:
the 32.5 lbs of meat is distributed between 5 lions so 32.5÷5=y

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.

Ms. Brown is preparing for an upcoming project in her art class. The students will be making paper mâché bowls and flowers. To prepare for the lesson, Ms. Brown needs to make the glue mixture that her students will be using. The mixture includes flour, water, and salt. For every 2 cups of flour she uses in the mixture, she also adds 5 cups of water and 1 tablespoon of salt.
Which statements are correct about the glue mixture?
Select the three correct statements.
A
There is 1 tablespoon of salt for each cup of water in the mixture
B
There are
2/5 cups of flour for each cup of water in the mixture.
C
There are 5/2 cups of flour for each cup of water in the mixture.
D
There is 1/2 tablespoon of salt for each cup of flour in the mixture.

Step-by-step explanation:
Multiply both sides by the reciprocal of the coefficient of c.
(5/2c)(2/5) = (8 1/3)(2/5)
c = (25/3)(2/5) = 50/(3·5) = 10/3
c = 10/3 = 3 1/3

Question in pic (50 points!)
Answer:
[tex]y=-\dfrac{5}{4}x+5[/tex]
Step-by-step explanation:
[tex]\boxed{\begin{minipage}{8cm}\underline{Slope Formula}\\\\Slope $(m)=\dfrac{y_2-y_1}{x_2-x_1}$\\\\where $(x_1,y_1)$ and $(x_2,y_2)$ are two points on the line.\\\end{minipage}}[/tex]
From inspection of the given graph, two points on the line are:
A = (0, 5)B = (4, 0)Substitute the two points into the slope formula to find the slope of the line:
[tex]\implies m=\dfrac{0-5}{4-0}=-\dfrac{5}{4}[/tex]
[tex]\boxed{\begin{minipage}{6.3 cm}\underline{Slope-intercept form of a linear equation}\\\\$y=mx+b$\\\\where:\\ \phantom{ww}$\bullet$ $m$ is the slope. \\ \phantom{ww}$\bullet$ $b$ is the $y$-intercept.\\\end{minipage}}[/tex]
From inspection of the given graph, the y-intercept is (0, 5), therefore b = 5. Substitute the found slope and y-intercept into the slope-intercept formula:
[tex]\implies y=-\dfrac{5}{4}x+5[/tex]
Answer:
Slope-intercept form
y = (-5/4)x + 5Step-by-step explanation:
The coordinates are,
→ x1 = 0, y1 = 5
→ x2 = 4, y2 = 0
Formula we use,
→ Slope(m) = (y2 - y1)/(x2 - x1)
Now the slope will be,
→ m = (y2 - y1)/(x2 - x1)
→ m = (0 - 5)/(4 - 0)
→ [ m = -5/4 ]
The y-intercept is,
→ y1 = 5
→ [ b = 5 ]
Then slope-intercept form is,
→ y = mx + b
→ y = (-5/4)x + 5
Thus, answer is y = (-5/4)x + 5.
