Using function concepts, it is found that:
1. The y-intercept of the graph of an equation will sometimes have a y-coordinate of 0.
2. If a linear equation contains only one variable, its graph will sometimes pass through the origin.
3. The statement is true.
What is the y-intercept of a function?The y-intercept of a function is the value of f(x) when x = 0, that is, the value of y for which the function crosses the y-axis.
If the function crosses the y-axis at y = 0, it will have a y-coordinate of 0, hence:
1. The y-intercept of the graph of an equation will sometimes have a y-coordinate of 0.
One example of linear equation with one variable is: y = 0.
Which passes through the origin, but y = 2 does not, hence:
2. If a linear equation contains only one variable, its graph will sometimes pass through the origin.
In item 3, the intercept is of By = 0 -> y = 0, hence when x = 0, y = 0, meaning that the statement is true, as the function will always pass through the origin.

A certain missing number will result in the expression 20 + 24 when using the Distributive Property. What number must be multiplied by ( 5 + 6 ) to result in the expression: 20 + 24
Answer:
4
Step-by-step explanation:
You want to know what number, multiplied by (5 +6), gives 20 +24.
Distributive propertyFor some number 'a', you want ...
a(5 +6) = (20 +24)
We can solve for 'a' in the usual way.
11a = 44 . . . . simplify
a = 44/11 = 4 . . . . divide by the coefficient of 'a'
The missing number is 4: 4(5 +6) = 20 +24.

You can also look at it term by term:
5a = 20 ⇒ a = 4
6a = 24 ⇒ a = 4 . . . . the same factor, as you want it to be

0.50 and 1 probability values indicates an event that is certain to happen
An event that is certain to happen has a probability of 1. An event that cannot possibly happen has a probability of zero. If there is a chance that an event will happen, then its probability is between zero and 1.
Probability of an event can not be negative.
We can easily discard first two options i.e. -0.80 and -0.60 as they are negative values.
Last two options i.e., 0.5 and 1 are positive values and they also lies in the range from 0 to 1. We can say that these values are considerable.

how this change will affect the area.
A. The area will be one-fourth the original area.
B. The area will be 4 times greater.
C. The area will be 16 times greater.
D. The area will be increased by 4 units.
If the side-lengths of a triangle are increased by a scale factor of 4 then the area will be 16 times greater.
As given in the question,
Let 'a' be the base of the triangle
and 'h' be the height of the triangle
Area of the triangle = (1/2)×a× h
Side length increased by scale factor 4
New base = 4a
New height=4h
New area=(1/2)×4a×4h
= 16×(1/2)×a ×h
= 16 times the original area
Therefore, if the side-lengths of a triangle are increased by a scale factor of 4 then the area will be 16 times greater.

SHOW WORK PLS AND THE EQUATION
Answer:
Let the number of 50p coins be x
and the number of 25p coins be 2x
Therefore,
Value of 50p coins = 50x p
and value of 25p coins = 2 * 25x p
= 50x p
Total value = Rs 34 = 34 * 100 p= 3400p
According to the question,
50x p + 50x p = 3400 p

The Johnsons have accumulated a nest egg of $40,000 that they intend to use as a down payment toward the purchase of a new house. Because their present gross income has placed them in a relatively high tax bracket, they have decided to invest a minimum of $2400/month in monthly payments (to take advantage of the tax deduction) toward the purchase of their house. However, because of other financial obligations, their monthly payments should not exceed $3000. If local mortgage rates are 4.5%/year compounded monthly for a conventional 30-year mortgage, what is the price range of houses that they should consider? (Round your answers to the nearest cent.)
Using the monthly payment formula, the price range of houses that they should consider is:
[$513,666.78, $592,083.48].
What is the monthly payment formula?It is given by:
[tex]A = P\frac{\frac{r}{12}\left(1 + \frac{r}{12}\right)^n}{\left(1 + \frac{r}{12}\right)^n - 1}[/tex]
In which:
P is the initial amount.r is the interest rate.n is the number of payments.For this problem, the parameters are given as follows:
r = 0.045 -> r/12 = 0.045/12 = 0.00375.n = 30 x 12 = 360.The minimum price, discounting the down payment, is found when A = 2400, hence:
[tex]A = P\frac{\frac{r}{12}\left(1 + \frac{r}{12}\right)^n}{\left(1 + \frac{r}{12}\right)^n - 1}[/tex]
[tex]2400 = 0.00375P\frac{(1.00375)^{360}}{(1.00375)^{360} - 1}[/tex]
[tex]P = \frac{2400[(1.00375)^{360} - 1]}{0.00375 \times (1.00375)^{360}}[/tex]
P = $473,666.78.
Considering the down payment, we add $40,000, hence the minimum value of the range is: $513,666.78.
The maximum price, discounting the down payment, is found when A = 3000, hence:
[tex]A = P\frac{\frac{r}{12}\left(1 + \frac{r}{12}\right)^n}{\left(1 + \frac{r}{12}\right)^n - 1}[/tex]
[tex]3000 = 0.00375P\frac{(1.00375)^{360}}{(1.00375)^{360} - 1}[/tex]
[tex]P = \frac{3000[(1.00375)^{360} - 1]}{0.00375 \times (1.00375)^{360}}[/tex]
P = $592,083.48.
Considering the down payment, we add $40,000, hence the maximum value of the range is: $592,083.48.
Hence the price range is:

The range is the difference between the highest and lowest values within a set of numbers. To calculate range, subtract the smallest number from the largest number in the set.The statistical distributions' characteristics are described by the terms mean, median, mode, and range. The set of all potential values for terms that indicate predetermined events is known as a distribution in statistics. A term's value stated as a variable is referred to as a random variable.
The two main categories of statistical distributions are as follows. There are discrete random variables in the first category. This indicates that each phrase has a distinct, precise numerical value. A continuous random variable is present in the distribution of the second major kind.

What is a relative frequency?A relative frequency is given by the number of desired outcomes divided by the number of total outcomes.
A frequency distribution is composed by the relative frequencies of each outcome. From the pie chart, we have that there is a total of 3 + 13 + 22 + 17 + 14 + 13 + 4 = 86 people, hence the frequency distribution is given as follows:
0-4: 3/86 = 0.0349.5-9: 13/86 = 0.1512.10-14: 22/86 = 0.2558.15-19: 17/86 = 0.1977.20-24: 14/86 = 0.1628.25-29: 13/86 = 0.1512.30: 4/86 = 0.0465.What are the mean and the standard deviation of a discrete distribution?The mean of a discrete distribution is given by the sum of each outcome multiplied by it's respective probability.The standard deviation of a discrete distribution is given by the square root of the sum of the differences squared between each observation and the mean, multiplied by their respective probabilities.This is relevant because we want to treat the frequency distribution as a discrete distribution, taking the midpoint of each interval, hence:
P(X = 2): 0.0349.P(X = 7): 0.1512.P(X = 12): 0.2558.P(X = 17): 0.1977.P(X = 22): 0.1628.P(X = 27): 0.1512.P(X = 32): 0.0465.Hence the mean is:
E(X) = 0.0349 x 2 + 0.1512 x 7 + 0.2558 x 12 + 0.1977 x 17 + 0.1628 x 22 + 0.1512 x 27 + 0.0465 x 32 = 16.71.
The mean is of 16.71.
The standard deviation is found as follows:
S(X) = sqrt[0.0349 x (2 - 16.71)² + 0.1512 x (7 - 16.71)² + 0.2558 x (12 - 16.71)² + 0.1977 x (17 - 16.71)² + 0.1628 x (22 - 16.71)² + 0.1512 x (27 - 16.71)² + 0.0465 x (32 - 16.71)²] = 10.95.
