Jane is 3 years older than Mary. Mary is twice as old as Kay. If Kay is x years how old is jane
Jane is 2x+3 years old. (answer)
In this case, we can use Kay as the base/foundation in this problem. Kay is x years old. Mary is twice as old as Kay, making Mary 2 times x or 2x. We are solving for Jane. Jane is 3 years older than Mary, who we know is 2x. We can add on 3 years making the final expression for Jane's age: 2x+3. Since we do not know Kay's age, or x, we cannot solve this problem any further.

An architectural company is trying to test the effectiveness of its promotional activity by looking at how many designs for
new buildings it sells each year.
Year Sales
2012 23
2013 18
The company assumes its promotional activity is less effective, which is why sales decreased. However, there could be many
confounding factors. Which of the following is not a possible confounding factor?
The factor that is not a possible confounding factor is B. the expected sales for the year 2014.
What is a confounding factor?A confounding factor is a third variable that influences or explains both the independent and dependent variables.
The independent variable here is the year while sales are the dependent variable.
However, confounding factors could include the number of new buildings constructed in 2013, which was not factored in by the architectural company and the state of the economy in 2013.
Thus, the expected sales for the year 2014 cannot be a confounding variable for the decreased sales in 2013 because it cannot explain the 2013 performance.

7x + (4x-21) = 12 -> 11x -21 = 12 -> 11x = 33 -> x = 3
plug x=3 into y=4x-21 to get
y = 4(3) - 21 = 12 - 21 = -9
Hall dimensions 200m by 85m. Diagram office wall scale 1:40. What are the dimensions of floor space in cm
The dimensions of floor is 500 cm by 212.5 cm
HOW TO FIND DIMENSION OF HALL ?Multiply the width and length of each rectangle to find its area. The areas of each rectangle are then added up to determine the total area. In the event that your room is L-shaped, for instance, this can be split into two rectangles. Additionally, this method still works in a complicated room.
CALCULATION500 cm by 212.5 cm
Given :
The main arena hall has dimensions 200 m by 85 m.
On a large diagram on the office wall the scale is 1:40.
Length of arena hall = 200 m
Scale is 1:40
So, the length of the floor =
Since 1 m = 100 cm
So, 5 m = 100*5 = 500 cm
Width of arena hall = 85 m
So, width of floor =[tex]\frac{85 * 1}{40}[/tex] = 2.125m
Now 1 m = 100 cm
So, 2.125 m = 212.5 cm
Thus the dimensions of floor is 500 cm by 212.5 cm

Answer:
Answers below
Step-by-step explanation:
To find per 20 miles
= 26miles/ 208minutes / 26 (to simplify)
= 1mile / 8minutes / 2 (to simplify)
= 1/2mile / 4 minutes x 40 (to get miles per 20 min)
= 20 miles / 160 minutes
_____________________________________________
To find per 15 miles
= 26miles/ 208minutes / 26 (to simplify)
= 1mile / 8minutes / 2 (to simplify)
= 1/2mile / 4 minutes x 30 (to get miles per 15 minutes)
= 15 miles / 120 minutes
_____________________________________________
To find miles per minute
= 26miles/ 208minutes / 26 (to simplify)
= 1mile / 8minutes / 8 (to get miles per minute)
= 0.125 miles / 1 minute

The container that holds the water for the football team is 2/5 full. After pouring in 6 gallons of water, it’s 7/10 full. How many gallons can the container hold
Answer:
20
Step-by-step explanation:
We need to determine what fraction of the container 6 gallons is. We know the difference between 2/5 and 7/10 is 6 gallons, so all we have to do is solve for 7/10 - 2/5. The common denominator is 10, as both 5 and 10 are factors of 10. 10/5 is 2, so we multiply the numerator of 2/5 by 2.
7/10 - 4/10 = 3/10
We now know that 6 gallons is 3/10 of the container. Now we solve.
10/3 = 3 1/3
So:
6 x 3 1/3 = 20
Answer:
20 gallons.-
Step-by-step explanation:
Let x be the number of gallons that the container holds.
The we have the equation
2/5 x + 6 = 7/10 x
Multiply through be 10
4x + 60 = 7x
3x = 60
x = 20.

(b)
How many successes were there in the Washington sample?
How many failures were there in the Washington sample?
(c)
Calculate a 95% confidence interval for the true difference in population proportions between the people of Washington, DC, and the people of Atlanta who agree with the statement (DC − Atlanta). (Use a table or technology. Round your answers to three decimal places.)
Step-by-step explanation:
Results of the Assembly elections in five States are indeed a shot in the arm for the Bharatiya Janata Party (BJP), which won in all four States where it was in power. The Hindu editorial captures the broad trends that emerge out of these results. Prime Minister Narendra Modi has said these results have sealed the outcome of the 2024 Lok Sabha elections too in the BJP’s favour. He said people have rejected caste and dynastic politics.
b. The number of successes in the Washington sample were 4740 .
The number of failures in the Washington sample is 1,260
c. the 95% confidence interval for the true difference in population proportions between the people of Washington, DC, and the people of Atlanta who agree with the statement "Employers should be required to pay men and women the same salary for the same job" is 0.018 to 0.068.
How do we calculate?(b) Number of successes and failures in the Washington sample:
Total number of respondents in the Washington sample: 6,000
Percentage who agreed with the statement: 79%
Number of successes = 79% of 6,000
= 0.79 * 6,000
= 4,740
Number of failures = Total - Number of successes
= 6,000 - 4,740
= 1,260
(c)
confidence interval = (p1 - p2) ± Z * √((p1 * (1 - p1) / n1) + (p2 * (1 - p2) / n2))
p1 = Proportion of successes in the Washington sample
p2 = Proportion of successes in the Atlanta sample
n1 = Size of the Washington sample
n2 = Size of the Atlanta sample
Z = Z-score for the desired confidence level = 1.96
confidence interval = (0.79 - 0.74) ± 1.96 * √((0.79 * (1 - 0.79) / 6000) + (0.74 * (1 - 0.74) / 4800))
confidence interval = 0.05 ± 1.96 * √((0.79 * 0.21 / 6000) + (0.74 * 0.26 / 4800))
confidence interval = 0.05 ± 1.96 * √(0.00013815 + 0.0001244583)
confidence interval = 0.05 ± 1.96 * √(0.0002626083)
Lower bound of the confidence interval (DC - Atlanta)
= 0.05 - 0.0317226549
= 0.018
Upper bound of the confidence interval (DC - Atlanta)
= 0.05 + 0.0317226549

based on the equation 5×x+860=2×x+380, you can say
The value of x is -160.
An equation in which the power of any variable is not more than one is called a linear equation.
Here, we are given a linear equation as follows-
5 × x + 860 = 2 × x + 380
⇒ 5x + 860 = 2x + 380
Let us solve the given equation-
Subtracting 2x from both sides, we get
5x - 2x + 860 = 2x - 2x + 380
3x + 860 = 380
Subtracting 860 from both sides-
3x + 860 - 860 = 380 - 860
3x = -480
dividing both sides by 3,
3x/3 = -480/3
x = -160
Thus, the value of x comes out to be -160.

Create a system of equations to represent this situation. Use the graph below and explain how many movies x would cause the 2 plans would have an equal monthly cost
Using linear functions, it is found that 4 movies would cause the two plans to have an equal monthly cost.
What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.For the functions in this problem, we have that:
The fixed cost is the intercept.The cost per movie is the slope.Hence the cost functions are given as follows:
C1(x) = 22 + x.C2(x) = 14 + 3x.The costs will be the same when:
C1(x) = C2(x).
Hence:
22 + x = 14 + 3x
2x = 8
x = 4.
4 movies would cause the two plans to have an equal monthly cost.
