By using ratio, it is obtained that if there are 8 atoms of hydrogen, there are 4 atoms of oxygen.
What is ratio?
Ratio is used to find a comparision between two quantities with the same unit
The first part of the ratio is called antecedant and the second part of the ratio is called consequent.
Here,
In a molecule of water, there are 2 atoms of hydrogen and 1 atom of oxygen
Ratio of hydrogen and oxygen = 2 : 1
Number of atoms of hydrogen = 8
Let the number of hydrogen atom be 2x and number of oxygen atom be x

Step-by-step explanation:
Given dimensions of a rectangular prism:
Width = (2x - 2) ftHeight = (x + 7) ftArea of the base = (3x² + 3x - 4) ft²
The area of the base of a rectangular prism is the product of the width of the base and the length of the base.

[tex]\begin{aligned}\implies \sf Area\;of\;base&=\sf length \times width\\&=b \times (2x-2)\\&=(3x-1)(2x-2)\\&=3x(2x-2)-1(2x-2)\\&=6x^2-6x-2x+2\\&=6x^2-8x+2\end{aligned}[/tex]

A certain insecticide kill 70% of all insects in a laboratory experiments A sample of 10 insects is exposed to the insecticide in a particular experiment what is the probability that exactly 3 insectswill die round your answer to four decimal places
Answers
The probability that exactly three insects will die is 0.343
Given 70% chance that an insect will die.
let A be the event that 1 insect dies.
P(A) = 0.7
The probability that the insect will not stay alive
= 1 - P(A)
= 1 - 0.7
= 0.3
Now there is a sample of 10 insects that are affected by the insecticide.
Therefore number of ways exactly 3 insects will die using binomial distribution is
= 10C3 × (0.7)³ × (0.3)⁷
= 120 × (0.7)³ × (0.3)⁷
=0.00901
≈ 0.009
Hence the required probability is 0.009 .
A probability distribution is an idealised frequency distribution. The frequency distribution of a certain sample or dataset serves as a description of it.
It is the frequency with which each conceivable value of the variable appears in the dataset. How frequently a value emerges in a sample is determined by its probability of occurrence.

Please help!!Here is a scale drawing of a playground. The scale is 1 centimeter to 30 meters. Make another scale drawing of the same playground at a scale of 1 centimeter to 20 meters. Take a picture of your drawing and upload it. Then, answer the following question: How do the two scale drawings compare?
Answers
Answer:
The second scale gives us a bigger drawing than the first scale.
Explanation:
Let's draw the initial scale figure with its measures in centimeters:
So, if the scale is 1 cm to 30 meters, the true length of side A will be:
[tex]A=2\operatorname{cm}\times\frac{30\text{ meters}}{1\text{ cm}}=60\text{ meters}[/tex]
In the same way, the true length of sides B and D of a playground is:
[tex]\begin{gathered} B=2\operatorname{cm}\times\frac{30\text{ meters}}{1\text{ cm}}=60\text{ meters} \\ D=4\operatorname{cm}\times\frac{30\text{ meters}}{1\text{ cm}}=120\text{ meters} \end{gathered}[/tex]
Now, if we scale the length in meters to centimeter but using the new scale 1 cm to 20 meters, we get that the new scale lengths will be:
[tex]\begin{gathered} A=60\text{ meters}\times\frac{1\text{ cm}}{20\text{ meters}}=3\text{ cm} \\ B=60\text{ meters}\times\frac{1\text{ cm}}{20\text{ meters}}=3\text{ cm} \\ D=120\text{ meters}\times\frac{1\text{ cm}}{20\text{ meters}}=6\text{ cm} \end{gathered}[/tex]
So, the new scale drawing is:
Then, we can compare both scale drawing and observe that the second scale gives us a bigger drawing than the first scale.

. You want to buy some underwear. Apackage of 8 costs $3.12. A package of 15costs $6.15. A package of 20 costs $7.60.Which package is the best buy?
Answers
We shall consider the options one after the other before choosing the best option;
Option 1;
[tex]\begin{gathered} \text{Pack of 8 costs 3.12} \\ 1\text{ unit = }\frac{3.12}{8} \\ 1\text{ unit=0.39} \end{gathered}[/tex]
Option 2;
[tex]\begin{gathered} \text{Pack of 15 costs 6.15} \\ 1\text{ unit=}\frac{6.15}{15} \\ 1\text{ unit=0.41} \end{gathered}[/tex]
Option 3;
[tex]\begin{gathered} \text{Pack of 20 costs 7.60} \\ 1\text{ unit=}\frac{7.60}{20} \\ 1\text{ unit=0.38} \end{gathered}[/tex]
Based on the calculations above, the third option is the best deal because that would make you pay the least amount per underwear. By choosing option 3, you will end up paying $0.38 for each underwear.
Therefore, "a package of 20 costs $7.60" is the best buy.

Answers
The coordinates of A' is (-0.5, 1)
What is Scale Factor?
To adjust the size of a figure without altering its shape, a scale factor is a number or conversion factor that is utilised. It is employed to change the size of an object.
A scale factor is a numerical value that can be used to alter the size of any geometric figure or object in relation to its original size.
Given:
A (-1,2) B(4,-3) and C (0,0)
First ABC is dilated by 0.5.
The transformation rule of this dilation is:
(x, y)--> 0.5 (x, y)--> (0.5x, 0.5y)
So, the coordinate of A' after dilation is
(-1, 2 ) --> 0.5(-1, 2)--> (-0.5 , 1)
Hence, the coordinates of A' is (-0.5, 1)

Using the conversion method, 4.6228 meter ribbon we need for craft project.
In the given question,
For a craft project you need 182 inches of ribbon, but it is only sold by the meter.
We have to determine the amount of ribbon, in meters.
As given 1 inch = 2.54 centimeters and 1 centimeter = 0.01 meter.
Firstly we know that inches, meters and centimeters all are units to measure the length.
Since we know that in 1 inch have 2.54 centimeters and 1 centimeters have 0.01 meter.
So we firstly convert the 2.54 centimeters in meter.
1 centimeter = 0.01 meter
2.54 centimeter = 2.54×0.01 meter
2.54 centimeter = 2.54×0.01 meter
2.54 centimeter = 0.0254 meter
So we can say that
1 inch = 0.0254 meter
We have to by 182 inches of ribbon. So
182 inches = 0.0254×182 meters
182 inches = 4.6228 meters
Hence, 4.6228 meter ribbon we need for craft project.

What is a linear function?
The slope-intercept representation of a linear function is given as follows:
y = mx + b
The coefficients of the function and their meaning are described as follows:
m is the slope of the function, representing the change in the output variable y when the input variable x increases by one, and the higher it's value, the higher the vertical increase of the function.b is the y-intercept of the function, which is the initial value of the function, that is, it's value when the function crosses the y-axis.
A proportional relationship is a linear function with intercept zero, hence it is given as follows:
y = mx.
Item a states that the students collect $24 for selling 10 raffles, hence the slope is:
m = 24/10 = 2.4.
Hence the equation is:
M = 2.4R.
If they sold 1000 tickets, the amount they would raise is of:
y = 2.4 x 1000 = $2,400.
The domain of this graph excludes negative values, as the number of raffles sold cannot be negative.
The function for item 4 is:
y = 3/11(x - 2).
Hence the intercepts are:
x-intercept (2,0).y-intercept (0, -6/11).

If Brady & Mathew knows that it will sell many of these cameras, should it expect to make or lose money from sell them? How much?
Answers
Given:
• Profit per camera = $186
,
• Cost of replacing the camera = $3100
,
• Probability it will be replaced once = 4% = 0.04
,
• Probability it will be replaced twice = 1% = 0.01
,
• Probability it will not be replaced = 95% = 0.95
Now, let's determine if the company should expect to make money or lose money from selling the camera.
Let's find the expected cost of repair.
We have:
E = (0.04 x 3100) + (0.01 x 2 x 3100) + (0.95 x 0)
E = 124 + 62 + 0
E = 186
Therefore, the expected cost of repair is $186.
We can see the profit per camera and the expected cost of repair are the same.
Profit per camera = Expected cost of repair
Since they are equal, the company should expect to neither make nor lose money from selling these cameras.
