Answer:
The two equations that passes through (2, -3) and has a slope of five are:
y + 3 = 5(x - 2) and y = 5x - 13
Step-by-step explanation:
For the first equation, you get y equal to itself. To do that, you need to simplify the right side of the equation. For 5(x - 2), you will distribute the 5 to the x and -2, equalling to 5x - 10. Next, we subtract 3 from both sides to cancel out the 3 on the left side. The equation is now y = 5x - 13. The -13 is the y intercept so we start at the point (0, -13). Since the slope goes up by 5 for every one point it moves to the right, it will eventually reach the point (2, -3). In other words, you add 1 to the x value and 5 to the y value. The points will look like this: it starts at (0, -13) and goes to (1, -8) and goes to (2, -3). The second equation is equivalent to the first equation. Hopefully this helps you out!
The ratio of Jaynee's money to Owen's money is 3:11. If Jaynee has $33,
how much money do Jaynee and Owen have ALL TOGETHER?
Answer:
42 dollars
Step-by-step explanation:
Jaynee's money is 11 out of (11+3) = 14 or 11/14ths of the total
11/14 x = 33
x = total amount = 33 * 14/11= 42 dollars
the length of pregnancy isn't always the same. in pigs, the length of pregnancies varies according to a normal distribution with mean 114 days and standard deviation 5 days. what percent of pig pregnancies are longer than 109 days?
95.61 percent of pig pregnancies are longer than 109 days with 0.8413 probability.
A standard normal distribution or z-table can be used to approximate the probability of multiple ranges of values for a random normal variable X with a particular mean and standard deviation. This method entails changing X to a typical normal variable Z.
The normal, random variable X equals the length of pregnancy.
The mean and standard deviation are then calculated.
u, Mean = 114 days
σ, Standard deviation = 5 days
Then, as follows, transform X to its standard normal variable:
Z = (X - u) ÷ σ
Z = (X - 114) ÷ 5
To determine the likelihood of a pregnancy lasting more than 109 days,
P(X ≤ 109) = P(Z ≤ 114 - 109 ÷ 5)
P(X ≤ 109) = P(Z ≤ 1)
P(Z ≤ 1) = 0.8413 when using a typical normal distribution or z-table.
The percentage of pig pregnancies that last more than 109 days,
P = (109 ÷ 114) × 100
P = 95.61%

What is meant by length of side?By dividing the base's length by its height, one may calculate any quadrilateral's surface area. We can conclude that all of the sides are the same length because the shape is square. Using the square root of the area to determine the length of one side, we can then work backwards from this information. A square has four sides, thus to determine the length of one side, divide the perimeter by 4. Assumed Area: Since s2 is the formula for a square's area and that number corresponds to one of its sides, you must get the square root of the area. A side is the line segment that connects two vertices of a shape or two-dimensional figure according to the definition of geometry.
Length of SU
= RS - RT - TU
= 24 - 12 - 6
= 24 - 1
= 6
Thus, the length of the US is 6 units.

Find the Standard deviation of 2, 2.6, 3.2, 4.3 5, 4.7, 6.2
The most appropriate choice for standard deviation will be given by-
Standard deviation is 1.41
What is Variance and standard deviation?
At first, it is important to know about mean of a data.
Mean gives the average value of the data.
Variance is calculated by taking the sum of the square of deviation of each value of the data set and then dividing the sum by the total number of values of the data set.
On taking the square root of the variance, we will obtain the standard deviation of the data set.
Here,
The data set is 2, 2.6, 3.2, 4.35, 4.7, 6.2
Mean = [tex]\frac{2 + 2.6 + 3.2 + 4.35 + 4.7 + 6.2}{6}[/tex]
= 3.84
Variance = [tex]\frac{(2-3.84)^2+(2.6-3.84)^2+(3.2-3.84)^2+(4.35-3.84)^2+(4.7-3.84)^2+(6.2-3.84)^2}{6}[/tex]
= [tex]\frac{11.9021}{6}[/tex]
= [tex]1.983[/tex]
Standard deviation = [tex]\sqrt{1.983}[/tex]

By applying a rotation of 180° counterclockwise to triangle ABC, we have the following:
The ordered pair for A' is (4, 0).The ordered pair for B' is (7, 2).The ordered pair for C' is (9, 9).What is a rotation?A rotation can be defined as a type of transformation which moves every point of the object through a number of degrees around a given point, which can either be clockwise or counterclockwise (anticlockwise) direction.
In Geometry, rotating a point 180° about the origin in a clockwise or counterclockwise (anticlockwise) direction would produce a point that has the coordinates (-x, -y).
By applying a rotation of 180° counterclockwise (anticlockwise) to triangle ABC, the coordinate of the image of triangle A'B'C' is given by:
(x, y) → (-x, -y)
Points at A = (-4, 0) → Points at A' = (-(-4), -(0)) = (4, 0)
Points at B = (-7, -2) → Points at B' = (-(-7), -(-2)) = (7, 2).
Points at C = (-7, -2) → Points at C' = (-(-9), -(-9)) = (9, 9).

c.) 5x – 50 = y and 4x – 46 = y
d.) 5 – 50x = y and 4 – 46x = y
Answer:
a
Step-by-step explanation:
Let's look at Enrique:
He starts with $50 and every time he buys lunch his account goes down by 5. The y would represent how much money he has left in his account.
So, say he buys 3 lunches how much is in his account if he started with 50?
50 - 5-5-5 = 35
Use the equation
50 - 5(3) = y
50 - 15 = y
35 = y

the graph represents the total number of plants and number of seed packets used. what i’d the constant of proportionality?
The constant of proportionality is 10 in the given graph which represents the total number of plants and number of seed packets used.
What is proportionality?Equivalence between two ratios is referred to as proportionality in algebra. A and B are in the same proportion as C and D in the expression a/b = c/d. When one of a proportion's four quantities is unknown, a proportion is typically used to solve a word problem.
It is resolved by multiplying one numerator by the opposing denominator and equating the result to that of the other numerator and denominator. Any relationship that always has the same ratio is referred to as proportional.
For instance, the ratio of proportionality is the average number of apples per tree, and the quantity of apples in a crop is proportional to the number of trees in the orchard.
Here, when number of seeds packet is 1 plants are 10 and when seeds packet are 5 plants are 50, we can divide each of the variables to find the constant,
10/1 = 10
20/2 = 10
30/3 = 10
Thus, constant is 10 represented as y = kx

Diana severs breakfast to two groups of children at a daycare center. One box of Oaties contains 12 cups of cereal. She needs ⅓ cup for each younger child and ¾ cup for each older child. Is one box of Oaties enough for everyone
One box of oaties will be enough for two groups of children.
We can state the box of oaties is enough for everyone, if the amount required by number of children in each group is less than or equal to 12.
So, amount of cereal required by younger/older children = amount required by one child × number of children
Amount of cereal required by younger children = 1/3 × 11
Amount of cereal required by younger children = 11/3 cups of cereal
Amount of cereal required by older children = 3/4 × 10
Amount of cereal required by younger children = 15/2 cups of cereal
Amount of cereal = 12 - (11/3 + 15/2)
Taking LCM in the bracket, we get 6
Amount of cereal = 12 - (11×2 + 15×3/6)
Solving the bracket
Amount of cereal = 12 - (22 + 45/6)
Performing addition = 12 - (67/6)
Amount of cereal = (12×6 - 67)/6
Amount of cereal = 72 - 67/6
Performing subtraction in numerator
Amount of cereal = 5/6
As 5/6 cups of cereal is remaining, thus, a box of oaties will be enough for 11 younger children and 10 older children.

What is an encyclopedia?
An encyclopedia (American English) or encyclopaedia (British English) is a reference source or compendium that provides summaries of general or specific information to a certain topic or discipline. Encyclopedias are organized into articles or entries that are either alphabetically sorted by article name or by subject categories, or are hyperlinked and searchable by random access. The entries in encyclopedias are longer and more thorough than those in most dictionaries. In general, encyclopedia articles focus on factual information about the subject specified in the title, as opposed to dictionary entries, which focus on linguistic information about words, such as their derivation, meaning, pronunciation, use, and grammatical forms.
Width of bookrack = 61 1/4 inches
Width of an encyclopedia = 1 3/4 inches
no. of encyclopedias to be fit = (61 1/4)/(1 3/4)
= (245/4)/(7/4)
