Answer:
Slope: [tex]-\frac{2}{5}[/tex]
Y-intercept: 2
Step-by-step explanation:
We have to isolate y;
2x + 5y = 10
5y = -2x + 10
y = [tex]\frac{-2x + 10}{5}[/tex]
y = [tex]-\frac{2}{5} x + 2[/tex]

Find the dividend if quotient is x–3, remainder is 7x–9 and divisor is x^2-2
Answer:
[tex]\implies Dividend = x^3-3x^2+4x-3[/tex]
Step-by-step explanation:
Given :-
Quotient is x–3, remainder is 7x–9 and divisor is x^2-2 .And we need to find out the Dividend. We know that ,
[tex]\implies Dividend = Quotient\times Divisor + Remainder [/tex]
Substituting the respective values :-
[tex]\implies Dividend = (x-3)(x^2-2)+7x-9 \\\\\implies Dividend = x^3-2x-3x^2+6+7x-9 \\\\\implies Dividend = x^3-3x^2+4x-3[/tex]

What is the median of the data?
Answer: Median: 10
Step-by-step explanation:
Answer: 10
Step-by-step explanation: First you place the numbers in order from least to greatest (5,5,7,9,11,12,16,23) then you take away one from each side at a time so 5,23 then 5,16 etc. you end up with 9 and 11 left so you find the middle of 9 and 11 which is 10.

A coin is tossed 10 times. 4 of the 10 tosses result in heads. What is the THEORETICAL probability of landing on heads
Answer:
1 /2
Step-by-step explanation:
The theoretical probability is the possibility of an event occurring based on reasoning and not on the outcome of a trial or experiment. Hence, for the question above, the outcome of the tosses or trials would have no effect on the theoretical probability that a coin lands oon head or tail.
Theoretical probability of an event =
Favorable outcome / Total possible outcomes
Favorable outcomes = number of heads in a coin = 1
Total possible outcomes = number of faces on a coin = 2 (head and tail)
Therefore,
Theoretical probability of landing on head = 1 /2
Subtract 2xy-8 from 5x^2+3xy+12
Answer:
5x^2 + xy + 20
Step-by-step explanation:
Begin with 5x^2+3xy+12, Subtracting 2xy yields 5x^2 + xy + 12. Next, subtracting -8 yields 5x^2 + xy + 12 - (-8), or 5x^2 + xy + 20

What is the meaning of f '' (4) = -4?
Hi there!
f''(4) = -4 means that at x = 4, the second derivative is equal to -4. This is equivalent to the instantaneous rate of change of the graph of f'(x) at x = 4 as well.
Answer:
Step-by-step explanation:
if the second derivative is -4 means that the function is concave down and that at point 4 the function has a maximum
Drag each tile to the correct box. Amanda, Derrick, and Todd attend the same high school. Each student works as the cashier one night a week at the school's concession stand. The number of items sold at the concession stand to the first 20 customers on three different nights is represented on the dot plots below. Find the interquartile range, IQR, for each dot plot. Then, place the students in order from greatest to least IQR.
Answer:
Amanda > Todd > Derrick
Step-by-step explanation:
Amanda's IQR- 3.5
Derrick's IQR- 2
Todd's IQR- 3
The solution is, ordering the IQR in descending order :
Emma, Sally, Olivia
What is IQR?The interquartile range (IQR) contains the second and third quartiles, or the middle half of your data set. Whereas the range gives you the spread of the whole data set, the interquartile range gives you the range of the middle half of a data set.
here, we have,
Writing out the points obtained from the dot plot, and applying the relevant formula, the Interquartile range of each dot plot is given below ;
Writing out each score on the dot plot to calculate the statistical values :
Emma's Scores:
6 , 7 , 8 , 8 , 9 , 9 , 9 , 10 , 10 , 11 , 11 , 11 , 11 , 11 , 12 , 13 , 13 , 13 , 13 , 14
Q1 = 1/4(n+1)th term
Q1 = (5th + 6th) terms
Q1 = (9 + 9) / 2 = 9
Q3 = 3/4(n+)th term
Q3 = (12 + 13) ÷ 2 = 12.5
IQR = Q3 - Q1
IQR = 12.5 - 9 = 3.5
Sally's Scores:
6 , 6 , 6 , 7 , 7 , 8 , 8 , 8 , 9 , 9 , 10 , 10 , 10 , 10 , 10 , 10 , 11 , 11 , 12 , 12 , 14
Q1 = 1/4(n+1)th term
Q1 = (7 + 8) ÷ 2 = 7.5
Q3 = 3/4(n+1)th term
Q3 = (10 + 11) ÷ 2 = 10.5
IQR = Q3 - Q1
IQR = 10.5 - 7.5 = 3
Olivia's Scores:
6 , 6 , 7 , 7 , 7 , 8 , 8 , 8 , 8 , 9 , 9 , 9 , 9 , 9 , 10 , 10 , 12 , 12 , 13 , 14
Q1 = 1/4(n+1)th term
Q1 = (7 + 8) ÷ 2 = 7.5
Q3 = 1/4(n+1)th term
Q3 = (10 + 10) ÷ 2 = 10
IQR = Q3 - Q1
IQR = 10 - 7.5 = 2.5
Therefore, ordering the IQR in descending order :

The horizontal cross section shown is a parallel to the base of the pyramid is the shortest side of the cross-section measures 1.2 cm what is the measure of the cross
Answer:
The longest side of the cross-section is: [tex]2.4cm[/tex]
Step-by-step explanation:
Given
See attachment for pyramid
Required
The longest side of the cross-section
The base of the pyramid is a rectangle with the following dimension (in terms of length)
[tex]Long = 6cm[/tex]
[tex]Short = 3cm[/tex]
For the cross-section, we have:
[tex]Long = x[/tex]
[tex]Short =1.2cm[/tex]
Since both are parallel, then the following relationship exist between both
[tex]Ratio = Long : Short[/tex]
So, we have:
[tex]6cm : 3cm = x: 1.2cm[/tex]
Express as fraction
[tex]\frac{6cm }{ 3cm }= \frac{x}{1.2cm}[/tex]
[tex]2= \frac{x}{1.2cm}[/tex]
Make x the subject
[tex]x = 2 * 1.2cm[/tex]
[tex]x = 2.4cm[/tex]

1. The graph below shows Calvin’s distance from home throughout the day
on Friday. He spent about 7 hours at school, 1 hour at a friend’s house,
and about 30 minutes at a store.
Answer:
Step-by-step explanation:
The solution is Option C.
The section on the graph which represents the equation at which Calvin spends his time at friend's house is section S
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
On a graph, a linear equation forms a straight line. On a graph, a nonlinear equation produces an S-curve, a bell curve, or another nonlinear shape.
Let the total time spend by Calvin at school = 7 hours
Let the total time spend by Calvin at friend's house = 1 hour
Let the total time spend by Calvin at a store = 30 minutes
From the graph , we can see that
The section Q represents the line from x = 1 to x = 8 which means a total time of 7 hours is spend by Calvin at school
And , section S represents the line from x = 9 to x = 10 which means a total time of 1 hour is spend by Calvin at friend's house
And , section U represents the line from x = 10.5 to x = 11 which means a total time of 30 minutes is spend by Calvin at a store
Hence , the solution is section S of on the graph
