I have the answers to the question but I’m not sure how they got them?
Answers
Hello there. To solve this question, we'll have to use the data from the graph (dot plot) and determine the answers for each letter.
a) How many babies begin walking before 13 months of age?
For this, we have to add all the number of babies walking from the dot plot that are less than 13.
In this case, we add the values of babies walking with 9, 10, 11 and 12 months:
1 + 1 + 3 + 5 = 10
Therefore 10 babies have begun walking before 13 months of age.
b) What percent of babies begin walking at 12 months?
For this, we add the entire number of babies walking by age and calculate the ratio between the number of babies walking at 12 months and this result.
We have 25 babies at total and 5 of them began walking at 12 months of age, so now we take the ratio:
[tex]\frac{5}{25}=\frac{1}{5}=20\%[/tex]c) Which three ages combined account for less than 16% of the babies?
For this, we find how many is 16% of 25, that is, the total of babies:
[tex]0.16\cdot25=4[/tex]So we have to find which three ages combined gives us less than 4 babies.
Notice we cannot choose the ages 12, 13, 14 because their number of babies, alone, are already bigger than 4.
We cannot also choose 11, because it is equal to 3 and all the other options are bigger than or equal to 1, so adding it with something else already would be equal to 4.
The same happens to 15 and 16, because their assigned value is 2, so adding both together gives us 4 and since all the others are greater than or equal to 1, we could not add other two together with them.
That's why the final answer is 9, 10 and 17, because they are the only numbers left that add up to 3 and this is a number less than 4, that is, less than 16% of the babies.
A desk is on sale for $380, which is 20% off the original price. Which equation can be used to determine theamount of money saved, s, in dollars, when purchasing this desk on sale?A s= 0.2(380)BS = (380 = 0.8) - 380Cs= (380 = 0.5) – 380D8 = (380 = 0.8)
Answers
Since the desk was 20% off, the price of $380 represents 80% of the original price.
Step 1. Define an expression to find the original price.
To find this original price, we divide the discounted price of 380 by the percentage it represents: 0.8 (we represent 80% in decimal form as 0.8)
[tex]380\div0.8[/tex]That expression represents the original price.
Step 2. To find the amount saved, we subtract the sale price to the original price:
[tex]s=(380\div0.8)-380[/tex]This expression will give as a result the amount saved s.

The slope (m) of the line using the given coordinates is 11/2 and the equation of the slope is plotted on the graph.
What do we mean by slope?The value of the steepness or the direction of a line in a coordinate plane is referred to as the slope of a line, also known as the gradient. Given the equation of a line or the coordinates of points situated on a straight line, a slope can be determined using a variety of approaches.A line's steepness can be determined by looking at its slope. The slope is calculated mathematically as "rise over run" (change in y divided by change in x).So, the slope formula is:
m = y₂ - y₁/x₂ - x₁Now, put the values and calculate as follows:
m = 33 - 11/6 - 2m = 22/4m = 11/2So, the slope equation will be:
y = mx + by = 11/2x + bNow, plot the graph of the equation, taking b = 1.
(Refer to the graph attached below)Therefore, the slope (m) of the line using the given coordinates is 11/2 and the equation of the slope is plotted on the graph.

What is angle sum property of a triangle?Angle sum property of triangle states that the sum of interior angles of a triangle is 180°.
Using angle sum property of triangle, we get
m∠X+m∠Y+m∠Z=180°

An aquarium is 0.5 feet wide, 1.5 feet tall, and 2 feet long.The bottom is covered with gravel to a height of 3 inches.The tank will be filled with water to 3 inches below the top.How many gallons of water are needed to fill the aquarium?(Use 1 gallon = 0.134 ft.) Ignore any water that might seepinto the layer of gravel. Round to the nearest tenth.
Answers
Step 1: Find the base area of the tank.
The base of the tank is a rectangle of length 2 ft and width 0.5 ft.
Hence,
[tex]\text{ the base area of the tank }=2ft\times0.5ft=1ft^2[/tex]Step 2: Find the height of the water in the tank.
The height of the tank = 1.5ft
the height of the gravel = 3in = 3/12 ft = 1/4 ft
The water is 3 inches (= 1/4 ft) below the top of the tank.
Hence, we must have that
[tex]\begin{gathered} x+\frac{1}{4}+\frac{1}{4}=1.5 \\ x+0.25+0.25=1.5 \\ x+0.5=1.5 \\ x=1.5-0.5=1\text{ ft} \end{gathered}[/tex]Therefore, the height of the water in the tank is 1 ft.
Step 3: Find the volume of the water in the tank
[tex]\begin{gathered} \text{ the volume of the water is given by} \\ V=\text{ base area of the tank }\times\text{ height of the water} \\ \text{ Where V is the volume of the water} \end{gathered}[/tex]Therefore,
[tex]V=1ft^2\times1ft=1ft^3[/tex]Since 1 gallon is equivalengt to 0.134 ft³ then
[tex]V=\frac{1}{0.134}\text{gallons }=7.5\text{ gallons}[/tex]Hence, the number of gallons of water are needed to fill the aquarium is 7.5 gallons.

Lonny takes a loan of 250000 and repays $1250 /month

p(6)=0 so x=6 is a root of a polynomial p(x).
Using factor theorem to find the remaining roots,

what is the slope of a passing line through the points(2, 5) and ( o, -4)?
Answers
The slope of the line is 9/2 passing line through the points(2, 5) and ( o, -4)
What is slope ?A line's slope is how steep it is moving from LEFT to RIGHT. The slope of a line is the ratio of its climb, or vertical change, to its run, or horizontal change. The slope remains consistent regardless of where you choose for the line's starting and finishing locations (it never changes).
CalculationWe know that the formula to find the slope of a line is
m = (y2 - y1) / (x2 - x1)
Where (x1, y1) and (x2, y2) are the points
The points given are (2, 5) and (0, -4)
Substituting it in the formula
m = (-4 - 5)/ (0 - 2)
So we get
m = -9/ -2
m = 9/2
Therefore, the slope of the line is 9/2.

Since the endpoints of the diameter are (10, 1) and (-8, 1)
Then the center of the circle is the midpoint of these 2 points
We will use the rule of the midpoint to find the center
[tex]M=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex][tex]\begin{gathered} M=(\frac{10+-8}{2},\frac{1+1}{2}) \\ \\ M=(\frac{2}{2},\frac{2}{2}) \\ \\ M=(1,1) \end{gathered}[/tex]The center of the circle is (1, 1)
The length of the diameter is the difference between the x-coordinate
