In this case the answer is very simple. .
Step 01:
Data
Kareem's gift card = $25
Medium coffee = $2.50
Step 02:
We can represent the number of coffees Kareen can buy using a linear equation.
x 1 = 0 coffee y 1 = $25
x2 = 1 coffee y2 = 25 - 2.50 = $22.50
Slope formula
\(m=\frac{y2\text{ - y1}}{x2\text{ - x1 }}=\frac{22.50-25}{1-0}=-2.50\)Point-slope form of the line
(y - y1) = m (x - X1)
( y - 25) = -2.50 ( x - 0)
y = -2.50 x + 25
The answer is:
slope: m = - 2.50
equation of the line: y = -2.50 x + 25
y intercept = 25

https://brainly.com/question/28276953
Answer:
Step-by-step explanation
1. The total cost of the trip for all 16 families is Rs 2,16,352.
2. To find out how much each family paid, we need to divide the total cost by the number of families: Rs 2,16,352 ÷ 16.
3. When we do the division, we get the result: Rs 13,522.
Now let's check if this result is correct:
1. If each family paid Rs 13,522 for the trip, then the total cost for all 16 families would be: 16 × Rs 13,522 = Rs 2,16,352.

Step-by-step explanation:
Luisa is solving an equation on the bottom of a page. The corner of the page where the
equation is written is torn off as shown below.
7(x + 3) = 7(x + 5)
Luisa knows only one number was torn off, and she knows that the equation has an infinite number of solu-
tions. What must be the missing number?
A 2
B 14
C 21
D 35
To solve the equation 7(x + 3) = 7(x + 5), we can start by simplifying both sides of the equation:
7x + 21 = 7x + 35
Subtracting 7x from both sides, we get:
21 = 35
This is a contradiction, as 21 is not equal to 35. Therefore, the equation has no solution.
However, the problem states that the equation has an infinite number of solutions. This can only happen if the missing number is a factor that appears on both sides of the equation, and therefore cancels out when we simplify the equation.
Looking at the equation, we can see that both sides have a factor of 7, which cancels out when we simplify the equation. Therefore, the missing number must be the factor that was torn off, which is 7 multiplied by the difference between the two numbers inside the parentheses:
7(5 - 3) = 14
Therefore, the missing number is 14, which corresponds to answer option B.
Hi can any one teach me this constant difference
The constant differences between the consecutive terms are 2 (a); 2 (b), -3 (c), 7 (d), 1(e), and 6(f).
How do you find the constant difference in a sequence of numbers?In math, the constant difference can be defined as the number that defines the pattern of a sequence of numbers. This means that number that should be added or subtracted to continue with the sequence.
Due to this, to determine the constant difference it is important to observe the pattern and find out the number that should be added. For example, if the sequence is 2, 4, 6, 8, there is a difference of 2 between each of the numbers and this is the constant difference.

Last year’s computer models are discounted 20%. What was the original price to the nearest dollar of a computer that now costs $1,480?
$1,184
$1,500
$1,510
$1,850
Answer:
x=$1850
Step-by-step explanation:
Let the original price of the computer model is x.
Last years discount is 20%
We need to find the original price if the computer now costs $1480.
ATQ,
\(x-20\%\ \text{of x}=1480\\\\x-\dfrac{20x}{100}=1480\\\\x-\dfrac{x}{5}=1480\\\\\dfrac{4x}{5}=1480\\\\x=\dfrac{1480\times5}{4}\\\\x=\$1850\)
So, the original cost of the computer model is $1850.

The answer is in the explanation
Step-by-step explanation:
This question didn't provide much information to begin with. But since I got the same question as well, I'll help.
First off, we're given g(0) = -2.
Looking from the choices we're given, we're most likely going to have to choose an answer that makes most sense.
'g(x) = 0' doesn't make sense with this function because in 'g(0) = -2' we can see the our y-intercept is -2, not 0.
Another answer we're given is a table. Looking at the data, it doesn't match with the equation we're given.
Another answer choice we're given are multiple points that form a linear function. The points on the graph, however, don't match with 'g(0) = -2. Considering this is graph is showing a linear line, the point that would go with the function 'g(0) = -2 is (-2,0). In this answer choice, we don't see a point at either options.
This leaves us with the graph that displays a exponential line. We can however, see that there's a point that does match with this equation. That point is (0,-2). Considering this graph is showing an exponential line, one of the points for our function 'g(0) = -2' would be (0,-2).

The data set {3, 7, 5, 4, 1} consists of the lengths, in minutes, of a sample of speeches at an awards banquet. Use a formula to find the standard deviation of the sample, and label it with the correct variable.
Answer:
Standard deviation = 2.2360679774998
Step-by-step explanation:
We are asked to find the Standard deviation of a samples of speeches as an awards.
The formula for sample standard deviation is given as:
√[(x - μ)²/N - 1 ]
Step 1
We find the mean (μ)
The mean of the sample =>
= Sum of term/ Number of terms
= (3 + 7 + 5 + 4 + 1)/5
= 20/5
= 4
Step 2
Find the Standard deviation of the sample
√[(x - μ)²/N - 1 ]
N = number of samples or terms = 5
= √[(3 - 4) ² + (7 - 4)² + (5 - 4)² +(4 - 4)² +(1 - 4)²/ 4]
= √ (1 ² + 3² + -1² + 0² + -3²/4)
= √( 1 + 9 + 1 + 0 + 9/4)
= √20/5 - 1
= √5
= 2.2360679774998
The standard deviation of the sample = 2.2360679774998

How many solutions does this system have? no solutions one unique solution O O two solutions O or an infinite number of solutions
Answer:
no solutions
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
equation of blue line is y = x + 2 , in slope- intercept form
with slope m = 1
equation of red line is y = x - 3 , in slope- intercept form
with slope m = 1
• Parallel lines have equal slopes
then the blue and red lines are parallel.
the solution to the system is at the point of intersection of the 2 lines
since the lines are parallel then they do not intersect each other.
thus the system shown has no solution.
mr. jones has a patio in the sahpe of a trapezoid. a round fountain having a circumference of 14 pi linear feet is placed in the corner as showin in the accompanying diagram. to the nearest square foot, how much of the patio s area ins not taken up by the fountanin? reall tha the circumferencie of a circle is calculated using c = 2
The area of the patio not taken up by the fountain is 241ft²
Please find attached an image of the patio
Area of the patio not taken up by the fountain = area of patio - area of fountain
The patio is in a shape of a trapezoid. Thus, the area of the patio can be determined by using the formula for the area of a trapezoid
A trapezoid is a convex quadrilateral. A trapezoid has at least on pair of parallel sides. the parallel sides are called bases while the non parallel sides are called legs
Characteristics of a trapezoid
It has 4 vertices It has 4 edges If both pairs of its opposite sides of a trapezoid are parallel, it becomes a parallelogramArea of a trapezoid = 0.5 x (sum of the lengths of the parallel sides) x height
Taking a look at the image, we are not provided with the height of the trapezoid, just the parallel sides and the hypotenuse.
Pythagoras theorem can be used to determine the the height of the trapezoid
The Pythagoras theorem : a² + b² = c²
where a = height
b = base = 20 ft - 12 ft = 8ft
8ft / 2 = 4
c = hypotenuse
a² + 4² = 25²
a² = 625 - 16
a² = 609
√609 = 24.68 ft
Area of the trapezoid = 0.5 x (20 + 12) x 24.68 = 394.88 ft²
The fountain is in the shape of a circle.
Area of a circle = πr²
Where : = π = pi = 22/7
R = radius
The radius would have to determined from the circumference
circumference of a circle = 2πr
14π = 2πr
r = 14π / 2π
r = 7
Area of the circle = \(\frac{22}{7}\) × 7²
\(\frac{22}{7}\) × 49 = 154 ft²
Area of the patio not taken up by the fountain = 394.88 ft² - 154 ft² = 240.88ft²
To round off to the nearest square, look at the first number after the decimal, if it is less than 5, add zero to the units term, If it is equal or greater than 5, add 1 to the units term.
The tenth digit is greater than 5, so one is added to 0. The number becomes 241ft²

For each description below, identify each underlined number as a parameter or statistic. Use appropriate notation to describe each number, e.g., .(a) Nationwide, 84% of people are living in the same house they were living in one year ago. The town council of Pleasant Valley surveys 100 residents and find that 75% of them have not moved in the past year.(b) The mean birthweight of infants in the United States in 2006 was 3.3 kg with a standard deviation of 0.57 kg. An obstetrician determines that among her own patients, the mean birthweight was 3.6 kg.
The mean birthweight of the obstetrician's own patients is higher than the national mean.
In the first description, 84% is a parameter, since it describes the population as a whole. The survey of 100 residents in Pleasant Valley yields a statistic of 75%, since it is a sample of the population.
In the second description, the mean birthweight of infants in the United States in 2006 of 3.3 kg and the standard deviation of 0.57 kg are both parameters. The mean birthweight of the obstetrician's own patients of 3.6 kg is a statistic. To calculate the difference between the two means, we can subtract the two values: 3.6 kg - 3.3 kg = 0.3 kg. This 0.3 kg difference indicates that the mean birthweight of the obstetrician's own patients is higher than the national mean.

Answer:
20 blogs
Step-by-step explanation:
Step 1: Determine the proportion of pop culture blogs:
First, we need to determine the proportion of pop culture blogs already written. We can do this by dividing the number of pop culture blogs already written by the total number of blogs written:
The proportion of pop culture bloggers = Number of pop culture bloggers / Total number of bloggers
Proportion = 26 / (20 + 26 + 7 + 12)
Proportion = 26 / 65
Proportion = 0.4
Step 2: Multiply the proportion of pop culture blogs by the number of upcoming blogs:
To determine the expected number of pop culture blogs that will be written given the data, we can multiply the proportion of pop culture blogs already written by the number of upcoming blogs:
Expected number of pop culture blogs = proportion of pop culture blogs * number of upcoming blogs
Expected number = 0.4 * 50
Expected number = 20
Thus, you should expect 20 pop culture blogs to be written given the data.
The volume of a box is 36 cubic inches. If the length is 3 inches and the width is 3 inches, what is the height of the box?
The height of the box is 4 inches.
The volume of a box is given by the formula V = lwh, where V is the volume, l is the length, w is the width, and h is the height. We are given that the volume of the box is 36 cubic inches, the length is 3 inches, and the width is 3 inches.
So, we can plug in these values into the formula and solve for the height h:
V = lwh
36 = 3 x 3 x h
36 = 9h
h = 36/9
h = 4
Therefore, the height of the box is 4 inches.
