so what is the question?
What is the slope of the line connecting the points (2, 1) and (4, 5)?
Answer:
2
use y2 - y1 / x2 - x1
5 - 1 / 4 - 2 = 4/2 = 2
Answer:
[tex]2[/tex]
Step-by-step explanation:
1. Find the difference between the two y values. 5 − 1 = 4
This is usually called the "rise" of the line.
2. Find the difference between the two x values. 4 − 2 = 2
This is usually called the "run" of the line.
3. Divide the rise buy the run: [tex]\frac{rise}{run} = slope \frac{4}{2} = 2[/tex]

20 POINTS!!!!!!!!!! what are two numbers that multiply to equal -13 but add to equal +7
Answer:
x = -1.525
y = 8.525
Step-by-step explanation:
xy = -13
x + y = 7
we can let 'y' equal 7-x and use substitution
x(7-x) = -13
7x - x² + 13 = 0
divide through by negative one to get a positive x²
x² - 7x - 13 = 0
use the quadratic formula to get:
x = -1.525
y = 8.525
A Carpenter was told to make
a rectangular desk with top
dimension of 50cm by40cm.
The Carperter altually made
the desk 60cm by 35cm.
Callulate the percentage
error in (a) the length and
b) the breath (1) the product
of the two enors (2) area of
the table top.
Answer:
a. Percent error = 12.5%
b. Percent error = 20%
c. Product = 250
d. Area of rectangle = 200 cm²
Step-by-step explanation:
Given the following data;
Actual length = 40cm
Experimental length = 35cm
Actual breadth = 50cm
Experimental breadth = 60cm
To find the following values;
a. Percentage error in length;
Percent error can be defined as a measure of the extent to which an experimental value differs from the theoretical value.
Mathematically, it is given by this expression;
[tex] Percent \; error = \frac {experimental \;value - actual \; value}{ actual \;value} *100[/tex]
Substituting into the formula, we have;
[tex] Percent \; error = \frac {35 - 40}{40} *100[/tex]
[tex] Percent \; error = \frac {5}{40} *100[/tex]
[tex] Percent \; error = 0.125 *100[/tex]
Percent error = 12.5%
b. Percentage error in breadth;
[tex] Percent \; error = \frac {60 - 50}{50} *100[/tex]
[tex] Percent \; error = \frac {10}{50} *100[/tex]
[tex] Percent \; error = 0.2 *100[/tex]
Percent error = 20%
c. Product of the error;
Product = 12.5 * 20
Product = 250
d. Area of the table top;
Dimensions = 50 * 40 cm
Area of rectangle = length * breadth
Area of rectangle = 40 * 50
Area of rectangle = 200 cm²
In the figure, side AB is given by the expression 1 + 3, and side BC is 21 – 4.
The simplified expression for the area of rectangle ABCD is
Answer:
[tex]\text{Area}=\frac{15(x+1)}{2(x-2)}[/tex]
Step-by-step explanation:
Length of the rectangle given in the picture = [tex]\frac{5x+5}{x+3}[/tex]
Width of the rectangle = [tex]\frac{3x+9}{2x-4}[/tex]
Area of the rectangle = Length × Width
= [tex]\frac{5x+5}{x+3}\times \frac{3x+9}{2x-4}[/tex]
= [tex]\frac{5(x+1)}{x+3}\times \frac{3(x+3)}{2(x-2)}[/tex]
= [tex]\frac{15(x+1)(x+3)}{2(x+3)(x-2)}[/tex]
= [tex]\frac{15(x+1)}{2(x-2)}[/tex]
Therefore, area of the given rectangle is [tex]\frac{15(x+1)}{2(x-2)}[/tex].

Answer:
G
Step-by-step explanation:
From the box plots given, the options that seem very much on support of the information given in the box plot is option G.
Median number in a box plot is the number at the point where the vertical line divides the box.
The median for Thin Crust is about 55 while the median for Thick Crust is above 55.
Therefore we can conclude that:
"The median number of orders for thick crust pizzas is larger than the median median number of orders for thin crust".
Indicate whether each statement about linear functions A and B shown below is true or false by checking the appropriate box in the table.

TRUE OR FALSE
The y-intercepts for both Function A and Function B are positive.
Answer: The rates of change for both function A and function B are positive : TRUE
The rates of change for functions A is 3 times the rate of change for function B : FALSE
The y - intercepts for both Function A and Function B are positive : FALSE

Which equation represents the following table?
Answer:
y = 2x+4
Step-by-step explanation:
When we substitute the value of x in y =2x+4. The output of function is exactly like in the table shown.
x = 1 —> y = 2(1)+4 = 6
x = 3 —> y = 2(3)+4 = 10
x = 5 —> y = 2(5)+4 = 14
x = 7 —> y = 2(7)+4 = 18
x = 9 —> y = 2(9)+4 = 22
Since the output is exactly like in the table. Therefore, y = 2x+4 represents the following table.
Q: using the Substitution Method, and the value ory in
Using the Substitution Method, find the value of y in
the below system of equations?
-2y = 44 – 4
7x = -4y + 10
Answer:
Step-by-step explanation:
To properly apply the substitution method, it will be better for us to rearrange the system of equations to have similar variables on the same side
[tex]44 - 4 = -2y ----equation 1[/tex]
[tex]10 = 7x + 4y --- equation 2[/tex]
We can simply evaluate equation 1 to have
[tex]40 = -2y\\y = 40/-2 = -20\\[/tex]
y = -20
From the first equation alone, we can evaluate the value of y as -20. This is because only one unknown is present in equation one, hence a single equation is sufficient enough to evaluate it. If to unknowns were present, the two equations would have been utilized to evaluate the solution.

can someone help me find the measure of the angle indicated in bold please
9514 1404 393
Answer:
A) 105°
Step-by-step explanation:
The two marked angles are alternate interior angles, so are congruent.
8x +17 = 9x +6
11 = x
8x +17 = 8(11) +17 = 88 +17 = 105 . . . . degrees
The bolded angle is 105°.
Answer:
105 degrees
Step-by-step explanation:
Here ,
8x+17=9x+6(being alternate angles )
17-6=9x-8x
11= x
Again,
8x-17=8×11+17
Therefore 8x-17=105 degrees

If a random sample of 26 text messages is taken and results in a sample mean of 28 characters, find a 98% confidence interval for the population mean. Round your answers to two decimal places. z0.10 z0.05 z0.04 z0.025 z0.01 z0.005 1.282 1.645 1.751 1.960 2.326 2.576
Answer:
The answer is "[tex](25.32, 30.68)[/tex]"
Step-by-step explanation:
Given:
[tex]\bar x = 28\\\\ \sigma = 4\\\\n =26\\\\[/tex]
When [tex]98\%[/tex] confidence level so, the z:
[tex]\alpha = 1 - 98\% = 1 - 0.98 = 0.2\\\\\frac{\alpha}{2} =\frac{0.02}{2} = 0.01\\\\Z_{\frac{\alpha}{2}} = Z_{0.01} = 1.645\ \ \ ( Using \ z \ table )\\\\[/tex]
[tex]E = Z_{\frac{\alpha}{2} \times ( \frac{\sigma}{\sqrt{n}})[/tex]
[tex]= 1.645 \times (\frac{4}{\sqrt{26}})\\\\=2.68[/tex]
When 98% confidence interval estimate of the population mean is,
[tex]\bar x - E < \mu < \bar x + E\\\\28 - 2.68 < \mu < 28 + 2.68\\\\25.32 < \mu < 30.68\\\\(25.32, 30.68)\\\\[/tex]

A lawn service owner is testing new weed killers. He discovered that a particular weed killer was effective 89% of time. Suppose that this estimate was based on a random sample of 60 applications. Find the lower confidence limit (LCL) for a 90% confidence interval for p, the true proportion of weeds killed by this particular brand. Round your answer to two decimal places.
Answer:
The LCL for a 90% confidence interval for p is 0.82.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].
A lawn service owner is testing new weed killers. He discovered that a particular weed killer was effective 89% of time. Suppose that this estimate was based on a random sample of 60 applications.
This means that [tex]\pi = 0.89, n = 60[/tex]
90% confidence level
So [tex]\alpha = 0.1[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.1}{2} = 0.95[/tex], so [tex]Z = 1.645[/tex].
The lower limit of this interval is:
[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.89 - 1.645\sqrt{\frac{0.89*0.11}{60}} = 0.8236[/tex]
Rounding to two decimal places, the LCL for a 90% confidence interval for p is 0.82.

1. Based on the information given, what is the Worthington Family's net worth? Will they qualify for the loan?
1
Net worth:
Will they qualify for the loan? (yes or no)
Question Completion:
The Worthington family has liquid assets of $10,000, use assets of $150,000 and investment assets of $34,000. They also have liabilities totaling $108,000. They need a loan from the bank and to qualify for the loan, they must have a net worth of $100,000. They will incur additional $7,000 in liabilities.
Answer:
1. The Worthington Family's net worth is:
= $79,000.
2. No. They will not qualify for the loan, as their net worth fell short of the requirement by $21,000.
Step-by-step explanation:
a) Data and Calculations:
Worthington Family's net worth:
Liquid assets = $10,000
Use assets = 150,000
Investment assets = 34,000
Total assets = $194,000
Liabilities = 115,000
Net worth = $79,000
Required net worth = $100,000
Shortfall in net worth = $21,000
b) The Worthington Family's net worth is the difference between their assets (the things that they own) and their liabilities (the things that they owe others). It is an important financial metric for calibrating the family's financial health. Computing it provides a useful snapshot of the family's current financial position. Financial institutions and other potential creditors use it to gauge if they might extend some credit facilities to the Worthington family.
A swimming pool is in the shape of this prism. A cubic foot of water is about 7.5 gallons. How many gallons of water can the pool hold? If a pump is able to pump water into the pool at a rate of 15 gallons per minute, how long will it take to fill the pool?
Answer:
48,000
Step-by-step explanation:
SOLUTION: Each cubic foot holds 7.5 gallons of water. So, the amount of water required to fill the pool is 6400(7.5) = 48,000.
x and y are two integers and x ≠ 0. Which of the following is not a rational number? a) z b) y c)x/y d) y/x
Answer: Choice A) z
==========================================================
Explanation:
x and y are two integers, with x being nonzero
This means x/y is rational as long as y is nonzero as well. If y = 0, then we have a division by zero error. Try something like 1/0 on your calculator and you'll find it doesn't work.
Similarly, y/x is rational as well. Any rational number is simply dividing two integers as a fraction like this. Other examples include stuff like 1/2, 4/5, 8/17, and so on.
Since y is an integer, this means we can write it like this: y = y/1. This shows any integer is also rational, but not the other way around. A fraction like 2/3 is rational but not an integer.
All of what was discussed above indicates that choices B, C and D can be ruled out. The only thing left is choice A. The variable z isn't defined, so it's not clear what it is exactly. But it's likely the answer as it's the only thing left after the eliminations.
