Given
\(\begin{gathered} 2x+3y=1470 \\ x\rightarrow\text{ number of sandwiches} \\ y\rightarrow\text{ number of wraps} \end{gathered}\)1) Solve for y to find the slope-intercept form, as shown below
\(\begin{gathered} \Rightarrow3y=1470-2x \\ \Rightarrow y=\frac{1470}{3}-\frac{2x}{3} \\ \Rightarrow y=-\frac{2}{3}x+490 \end{gathered}\)The slope-intercept form of the equation is y=-2x/3+490, where -2/3 is the slope and +490 is the y-intercept.2) To graph the equation, start at (0,490), the y-intercept; then, move 3 units to the right for every 2 units down because the slope is -2/3.For example, to the right of (0,490) we can find (0+3,490-2)=(3,488)
3) From part 1), notice that to the right of the equality there are only terms of x; then, we can rewrite it as shown below
\(\begin{gathered} y=f(x) \\ \Rightarrow f(x)=-\frac{2x}{3}+490 \end{gathered}\)The graph of f(x) is the number of wraps as a function of the number of sandwiches (x).4)
5)
The slope of the two lines will be the same since the ratio cost of a sandwich to the cost of a wrap stays the same; in contrast, the value of the y-intercept will be different because the total profit is now $1593 rather than $1470

which algebra tiles are used in this equation:
4x + 7 = 23
Answer:
4x+7=23
4.4+7=23
Step-by-step explanation:
23-7=16
16/4=4
The algebra tiles used in the equation 4x + 7 = 23 are four x-tiles, seven unit tiles, and 23 unit tiles.
To model the equation 4x + 7 = 23 using algebra tiles, we would use variable tiles (x-tiles) and unit tiles.
For the term 4x, we would use four x-tiles since the coefficient is 4.
For the term 7, we would use seven unit tiles since it is a constant.
The equal sign (=) does not have a specific tile representation; it simply indicates the equation's balance.
On the other side of the equation, for the term 23, we would represent it using 23 unit tiles.
So, the algebra tiles used in this equation would be four x-tiles, seven unit tiles, and 23 unit tiles.

an outdoor theater currently has 1,375 ft next year 125 news seats will be added there will be 25 ft in each row after the new seeing has been added how many rows would a theater have after the new seats have been added?
The total number of rows in the Theater after 125 seats are added is 60 rows.
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
The Outdoor theater currently has 1,375 seats.
If we add 125 new seats then the number of seats are
= 1375 + 125
= 1500
Each row have 25 seats in one row.
Then, the total number of rows in Theater
= 1500/25

Answer:
See below.
Step-by-step explanation:
STEP 1: If you write the given terms all with denominators of 16, they are 28/16, 25/16, 22/16, 19/16, __, ____, ____, 7/16, 4/16.
STEP 2: The terms decrease by 3/16 for each step.
RULE: Term 1 = 7/4 and term (n + 1) = term 'n' - 3/16
The operation for increasing by the same amount every step is addition.
The operation for decreasing by the same amount every step is subtraction.
STEP 3: The rule is that the terms decrease by 3/16 at each step.
So the next 3 terms after 19/16 will be 16/16, 13/16, and 10/16.
Reformat them and you have 1, 13/16, 5/8.
So now the completed sequence is 1&3/4, 1&9/16, 1&3/8, 1&3/16, 1, 13/16, 5/8, 7/16, 1/4.

Solution(s):
q11: 5
q12: 36
q13: k=5w+36
q14: The first option
Explanation:
Question in your given image:
Duk collected 36 grams of pebbles for his large yard. He plans to collect an addition 5 kg each week.
For Question #11 and Question #12, based of the question from above we can conclude that the slope is the value 5 and the y-intercept is the value 36.
Question #13 asks us to represent the situation as an equation where "k" represents the total amount of pebbles (in kg) after "w" number of weeks.
This is simply a linear equation and we can use the slope-intercept formula, y=mx+b. Where "m" is the slope and "b" is the y-intercept.
Substitute the values we know into "m" and "b." We would have,
==> y=5x+36
What variables replace x and y? Well x is the input value and we want to input the number of week "w." y is the output value from which we can see the total mass of pebbles so "k" is the correct substitution.
Thus, to answer question #13, k=5w+36.
For the final question we already answered it.
x=input value=w(amount of weeks) and y=output value=k(total pebbles in kg)

y-1= 3/4(x +3)
Answer:
slope= 3/4
point on the line = (-3, 1)
Step-by-step explanation:
Given the point-slope equation: y - y1 = m(x - x1),
where:
m = slope
(x1, y1) = point on the line
In your given point-slope equation:
y - 1 = 3/4( x + 3 )
slope (m) = 3/4
and the point on the line is (-3, 1).
If you plug in the given point on the line (-3, 1) and the slope (m = 3/4) in the point-slope form:
y - y1 = m(x - x1)
y - 1 = 3/4(x - (-3))
Then it will become:
y - 1 = 3/4(x + 3) because negative multiplied by a negative will become a positive number.
Therefore, the correct answers are:
slope= 3/4
and the point on the line is (-3, 1).

The observations X1, . . . , Xn have a mean of 52, a median of 52.1, and a standard deviation of 7. Eight percent of the observations are greater than 66; 7.9% of the observations are below 38. Based on this information, which of the following statements best describes the data?
a. The distribution has positive skew.
b. The distribution has negative skew.
c. The distribution has high kurtosis.
d. The distribution conforms to a normal distribution.
Answer:
d. The distribution conforms to a normal distribution.
Step-by-step explanation:
A normal distribution is when data has equal symmetry such that the distribution is not positive skewed nor negative skewed. A normal distribution has zero skewness as mean, median and mode are all equal.
In the above example, the data has a normal distribution because most values lie close to the mean(7.9 percent are less than 38 and 8 percent are more than 66)

you and your friend are debating about which singer is better, harry styles or taylor swift. a random sample of reviews were taken from spotify for both singers, 300 reviews for harry styles and 200 reviews for taylor swift.
Student t distribution will be used to test the hypothesis that both singers have same average rating.
An inferential statistic called a t-test is used to assess whether the means of two variables differ statistically significantly.
Three basic data values are necessary to calculate a t-test. They consist of the variation in mean values, the standard deviation, and the total amount of data values for each group.
The numerator value is the difference between the two sample sets' means.
The variance present in the sample sets serves as the denominator and serves as a gauge of dispersion or variability.
Then, this determined t-value is contrasted with a figure taken from a critical value table.
A significant difference is shown by higher t-score values. The more similar the two sample sets are, the smaller the t-value.

She uses the most hard words, examples, vocals, and lyrics, which she executes flawlessly. She has won so many awards, including 12 Grammys, which 3 of them are for album of the year. Taylor Swift is the music industry.

1. Initial prediction for the data set with smaller Mean Absolute Deviation was Period A. Prediction was wrong.
2. The Mean Absolute Deviation for Period A is 1.8 and Period B, 1.1
This means that period B has a smaller Mean absolute deviation.
How do we calculate the Mean Absolute Deviation?We start by finding the mean for each set;
Period A: Mean = (1×92 + 1×94 + 3×95 + 1×96 + 2×97 + 1×99 + 1×100)/10
= 960/10
= 96
Period B: Mean = (1×94 + 3×95 + 1×96 + 4×97 + 1×98)/10
= 961/10
= 96.1
Period A:
Mean Absolute Deviation = ((92-96) + (94-96) + 3(95-96) + (96-96) + 2(97-96) + (99-96) + (100-96))/10
Mean Absolute Deviation = (4 + 2 + 3 + 0 + 2 + 3 + 4)/10
Mean Absolute Deviation = 1.8
Period B:
Mean Absolute Deviation = ((94-96.1) + 3(95-96.1) + (96-96.1) + 4(97-96.1) + (98-96.1))/10
Mean Absolute Deviation = (2.1 + 3.3 + 0.1 + 3.6 + 1.9)/10
Mean Absolute Deviation = 1.1
