Write a linear equation expressing the number of t-shirts sold each month as a function of price per t-shirt. Please be explicit about what your chosen variables represent. Find the slope and intercepts of this equation. What real life meaning do these values have?
Answer:
t = c - bp
Step-by-step explanation:
Where : t = number of t shirts sold per month ,
p = price per t shirt
Equation of t shirts sold in terms of price per t shirt , ie t = f (p) , is -
t = c - bp
As per law of demand - other factors remaining constant, price & sale demand of a product are inversely related to each other.
In equation- Negative intercept of 'p' in defining 't' denotes this inverse relationship. c denotes the constant autonomous value in the equation. b denotes the slope of demand equation, which signifies demand change in response to price change.

Answer:
a = 0.3
b = 0.4
c = 40%
d = 15%
Step-by-step explanation:
There are a total of 10 tick marks. So we know that 1 tick mark = 10%
a has 3 tick marks so you can say it's 0.3
b has 4 tick marks so you can say it's 0.4
c also has 4 tick marks, but it's asking for the percentage, so you get 40%
d is 1 1/2 tick marks. It's also asking for percentage. You know 1 tick = 10% and 1/2 tick = 5* so d = 15%

Dennis is getting balloons for his grandmother's birthday party. He wants each balloon string to be 9 feet long. At the party store, string is sold by the yard. If Dennis wants to get 56 balloons, how many yards of string will he need?
1 foot = 1/3 yard
Answer:
168 yards
Step-by-step explanation:
3 feet = 1 yard
9 (ft for each balloon) x 56 (# of balloons.) = 504 (ft of string needed in total)
504 (ft in total) divided by 3 (three feet = 1 yard) = 168 (yards of string needed)

You are estimating the cost of optical sensors based on the resolution of the sensor. You decide to calculate the coefficient of determination (R2) as part of determining the goodness of fit of an equation. Using the preliminary calculations below, calculate the R2 and determine its meaning.
Summation of (Yi - Ybar)2 = 147172
Summation of (Yhat - Ybar)2 = 130542
Summation of (Y - Yhat)2 = 16630
a. 88.70% of the variation in the cost is being explained by the resolution.
b. 88.70% of the variation in the resolution is being explained by the cost.
c. 11.30% of the variation in the resolution is being explained by the cost.
d. 11.30% of the variation in the cost is being explained by the resolution.
Answer:
a. 88.70% of the variation in the cost is being explained by the resolution.
Step-by-step explanation:
Given :
Summation of (Yi - Ybar)2 = 147172
Summation of (Yhat - Ybar)2 = 130542
Summation of (Y - Yhat)2 = 16630
The Coefficient of determination (R²) :
Sum of Square regression (SSR) / sum of square TOTAL (SST). It gives the percentage of the dependent variable which can be explained by the regression line.
Cost is the dependent variable in this scenario.
SSR = Summation of (Yhat - Ybar)2 = 130542
SST = Summation of (Yi - Ybar)2 = 147172
Hence,
SSR / SST = 130542 / 147172
R² = 130542 / 147172
R² = 0.8870029 = (0.8870029 * 100%) = 88.7%
pls answer, show work A jacket at a clothing store is being discounted by 10%. If the jacket was originally priced at x dollars, which of the following expressions does NOT represent the final price of the jacket before sales tax is added?
A.
x – 0.10x
B.
x(1 – 0.10)
C.
x – 1.10x
D.
0.90x
Answer:
C
Step-by-step explanation:
This is the only possible correct answer because the other three all show the final price as 0.90x, which is correct since the price is the normal one minus 10 percent. C is incorrect because it suggests the normal price has a 10% tax, or extra value on it.

Lauren has a purse full of dimes and quarters. She has 25 less dimes than quarters. If she has a total of $10.45, which system of equations would she write to find the number of dimes, d and quarters, q?
Answer:
D(0.10) + Q(0.25) = 10.45
Q = D + 25 (or Q - D = 25)
Step-by-step explanation:
D = number of dimes
Q = number of quarters
D(0.10) + Q(0.25) = 10.45
Q = D - 25 (or D - Q = 25)
We multiply the number of dimes she has by $0.10, because that is the worth of each dime, and we multiply the number of quarters she has by $0.25 because that is the worth of each quarter. We then set that equal to $10.45, the overall value of her coins.
Because she has 25 less dimes than quarters, the number of dimes she has should be 25 less than the number of quarters she has. So the number of quarters she has should be equal to the number of dimes she has plus 25.
What is the value of x in the figure? Enter your answer in the box. 145 degrees and (2x + 15) degrees
Answer:
65°
Step-by-step explanation:
2x + 15° = 145° ( being vertically opposite angles)
2x = 145° - 15°
2x = 130°
x = 65°
Hope it will help :)✔
The value of x is 65 degrees.
What is Vertically opposite angle?When two lines intersect each other, then the opposite angles, formed due to intersection are called vertical angles or vertically opposite angles.
Given:
angles are: 145 and (2x +15)
As, the pair of angle are in relation of vertically opposite angle
145 = 2x +15
2x= 130
x= 130/2
x= 65 degree.
