Write an additional word problem in which the estimated sum is 14,000
The problem is about estimating the total sales sum of 7 TVs sold in a day, each priced at approximately $2,000, which gives us a total estimate of $14,000.
Explanation:The mathematics problem could be something along the lines of this: In a local electronics store, 7 high-definition smart TVs were sold in one day. If each TV is approximately priced at $2,000, what is the estimated total sales sum for that day?
First, analyze the problem. We want to find the estimated total sales sum for the smart TVs.Then, we use estimation to solve it. We know each TV costs around $2,000 and that 7 TVs were sold.Just multiply $2,000 by 7. Thus, $2,000 * 7 = $14,000So, the estimated sum is $14,000This estimation gives us a total sum of $14,000, which is close to the actual total if each TV is priced at $2,000.

In triangle JKL, if line JK is equal to line JL, angle J equals 23x-4, angle K equals 4x-1, and angle L equals 9x-31, find x and the measure of each angle.
m(∠J) = 134°, m(∠K) = 23° and m(∠L) = 23° is the answer.
From the figure attached,
JK and JL are equal sides of the triangle.m(∠J) = 23x - 4m(∠K) = 4x - 1m(∠L) = 9x - 31Since, two sides JK and JL of ΔJKL are equal in measure,
Therefore, ΔJKL is an isosceles triangle.
By the property of an isosceles triangle, opposite angles of the equal sides are equal.
Therefore, m(∠K) = m(∠L)
4x - 1 = 9x - 31
9x - 4x = 31 - 1
5x = 30
x = 6
By substituting the value of 'x' in the measures of each angle,
m(∠J) = 23x - 4
= 23(6) - 4
= 138 - 4
= 134°
m(∠K) = 4x - 1
= 4(6) - 1
= 24 - 1
= 23°
m(∠L) = 9x - 31
= 9(6) - 31
= 23°
Therefore, m(∠J) = 134°, m(∠K) = 23° and m(∠L) = 23° will be the answer.

Estimate 27.89 • 10.3 divided by 4.37 using compatible numbers
The profits of a company are found by subtracting the company's costs from its revenue. If a company's cost can be modeled by 14x + 120,000 and its revenue can be modeled by 40x - 0.0002x^2, what is an expression for the profit?
The profit function is given by [tex]\( P(x) = -0.0002x^2 + 26x - 120,000 \).[/tex]
To find the expression for the profit, we need to subtract the cost function from the revenue function.
Given:
Cost function: [tex]\( C(x) = 14x + 120,000 \)[/tex]
Revenue function: [tex]\( R(x) = 40x - 0.0002x^2 \)[/tex]
The profit function, ( P(x) ), is given by:
[tex]\[ P(x) = R(x) - C(x) \][/tex]
Substitute the given functions into the profit function:
[tex]\[ P(x) = (40x - 0.0002x^2) - (14x + 120,000) \][/tex]
Now, let's simplify:
[tex]\[ P(x) = 40x - 0.0002x^2 - 14x - 120,000 \][/tex]
[tex]\[ P(x) = 26x - 0.0002x^2 - 120,000 \][/tex]
This is the expression for the profit:
[tex]\[ {P(x) = -0.0002x^2 + 26x - 120,000} \][/tex]
So, the profit function is given by [tex]\( P(x) = -0.0002x^2 + 26x - 120,000 \).[/tex]

Carl is boarding a plane. He has 2 checked bags of equal weight and a backpack that weighs 4 kg. The total weight of Carl's baggage is 35kg. Write an equation to determine the weight, w ww, of each of Carl's checked bags. Find the weight of each of his checked bags.
Answer:
15.5 kg (each)
Step-by-step explanation:
Let [tex]w[/tex] be the weight of each checked bag (there are 2). Thus, we can write, from the information given:
[tex]w+w+4=35\\2w+4=35[/tex]
Now we solve this equation for [tex]w[/tex] to find weight of each checked bag:
[tex]2w+4=35\\2w=35-4\\2w=31\\w=\frac{31}{2}\\w=15.5[/tex]
So, the weight of each of his checked bags is 15.5 kg.
A clinical trial was conducted to test the effectiveness of the drug zopiclone for treating insomnia in older subjects. before treatment with zopiclone, 16 subjects had a mean wake time of 102.8 minutes. after treatment with zopiclone, the 16 subjects had a mean wake time of 98.9 minutes and a standard deviation of 42.3 minutes (based on data from cognitive behavioral therapy vs zopiclone for treatment of chronic primary insomnia in older adults," by silverstein et al., journal of the american medical association, vol. 295, no. 24). assume that the 16 sample values appear to be from a a normally distributed population and construct a 98% confidence interval estimate of the mean wake time for a population with zopiclone treatments. what does the result suggest about the mean wake time of 102.8 minutes before the treatment
To construct a 98% confidence interval estimate of the mean wake time for a population with zopiclone treatments, use the formula: Confidence interval = sample mean ± (critical value * standard deviation / square root of sample size).
Explanation:To construct a 98% confidence interval estimate of the mean wake time for a population with zopiclone treatments, we can use the formula:
Confidence interval = sample mean ± (critical value * standard deviation / square root of sample size)
Given that the sample mean after treatment with zopiclone is 98.9 minutes, the standard deviation is 42.3 minutes, and the sample size is 16, we need to find the critical value for a 98% confidence level. The critical value can be found using a t-distribution table or calculator.
Once the critical value is obtained, we can plug in the values into the formula to calculate the confidence interval estimate.
Graph each line y -7 = x + 4
To graph y - 7 = x + 4, rewrite the equation in slope-intercept form as y = x + 11. Plot the y-intercept at (0, 11), choose another value for x to find a second point, like (1, 12), and draw the line through these points to visualize the dependence of y on x.
Explanation:To graph the line given by the equation y - 7 = x + 4, we first need to write it in the slope-intercept form, which is y = mx + b, where m is the slope and b is the y-intercept. So, we add 7 to both sides of the equation to get y = x + 11. This tells us the slope of the line is 1 (since for every increase by 1 in x, y increases by 1) and the y-intercept is 11 (this is where the line crosses the y-axis).
We can then plot the y-intercept on the graph by putting a point at (0, 11). To find another point, we can choose any value for x and solve for y. For example, if we choose x = 1, then y = 1 + 11 = 12, so another point on the line is (1, 12). By plotting these two points and drawing a line through them, we create the graph of the equation.
For more accurate results, plotting more points using various x values and connecting them would be ideal. This graphical representation illustrates the dependence of y on x.

does velocity or mass impact momentum more and why
Both mass and velocity equally affect momentum in classical physics. However, at relativistic speeds, velocity has a more significant effect on momentum due to relativistic mass increase.
Explanation:The impact of mass and velocity on momentum depends on the context of the object's motion. In classical physics, momentum is defined as the product of an object's mass and velocity, thus both mass and velocity equally influence momentum. However, for objects moving at relativistic speeds—approaching the speed of light—the effect of velocity on momentum is more pronounced due to the relativistic mass increase. To illustrate, a football player with greater mass has a larger impact due to having more momentum when moving at the same velocity as a player with less mass. In contrast, at relativistic speeds, an increase in velocity would result in an exponentially greater momentum, surpassing the effect of just increasing mass.
