Find the x and y intercepts of 4x - 5y = 40
Is this correct and can someone explain why??
Answer:
no, the correct answer is D.
Step-by-step explanation:
for the x-intercept you would first add 5y to both sides giving you 4x=5y+40. then you would divide both sides by 4, so the final equation would be x=5/4y+10.
for the y-intercept you would subtract 4x from both sides, making -5y=-4x+40. then you would divide both sides by -5, making the final equation y=4/5x-8.

Which is the better definition of line of best fit?
A line of best fit guides a line through a scatter plot of data points that best describes the association between those points.
What is line of best fit?
A line of best fit guides a line through a scatter plot of data points that best describes the association between those points. Statisticians typically utilize the least squares approach to arrive at the geometric equation for the line, either through manual computations or regression analysis software.
A line of best fit can be approximately specified utilizing an eyeball the method by marking a straight line on a scatter plot so that the numeral of points above the line and below the line stands about equal (and the line passes via as many points as possible).

Answer: 3 is in the domain of f(g(x)). Step-by-step explanation: ... What is the domain of the given function? a) {x | x = –6, –1, 0, 3}; {y | y = –7, –2, ...
The domain is all real numbers except 9 (positive)
This is because we can't have 0 in the denominator, and when x equals 9, then the denominator is 0. Anything divided by 0 is undefined, which is why 9 (in this equation) is not included.
Answer:

A woman decides to have children until she has her first girl or until she has five children; whichever happens first. Find the expected value and standard deviation of X. Let X represent the number of children she has. Assume that she is equally likely to give birth to a boy or a girl on each child, and that gender is independent between children.
(a) Write out and sketch the complete probability distribution function for X.
(b) Write out and sketch the complete cumulative distribution function for X.
(c) Find the expected value and standard deviation of X.
Answer:
E(X) = 1.9375
SD(X) = 1.20
Step-by-step explanation:
Let :
G = girl ; B = Boy
P(G) = 0.5 ; P(B) = 0.5
Sample space :
G, BG, BBG, BBBG, BBBBG, BBBBB
Using the multiplication rule of independence :
P(G) = 0.5
P(BG) = 0.5 * 0.5 = 0.25
P(BBG) = 0.5 * 0.5 * 0.5 = 0.125
P(BBBG) = 0.5 * 0.5 * 0.5 * 0.5 = 0.0625
P(BBBBG) = 0.5 * 0.5 * 0.5 * 0.5 * 0.5 = 0.03125
P(BBBBB) = 0.5 * 0.5 * 0.5 * 0.5 * 0.5 = 0.03125
Creating a probability distribution table :
X = 1, 2, 3, 4, 5
For X = 5 ;
P(BBBBG) + P(BBBBB) = 0.03125 + 0.03125 = 0.0625
X :___ 1 ____ 2 ____ 3 _____ 4 _____ 5
P(X) : 0.5 __ 0.25 _ 0.125 _0.0625 _0.0625
The expected value E(X) :
√(ΣX * P(X)) = (1*0.5)+(2*0.25)+(3*0.125)+(4*0.0625)+(5*0.0625) = 1.9375
The standard deviation SD(x) :
√(ΣX²*p(x) - E(X)²
√((1^2*0.5)+(2^2*0.25)+(3^2*0.125)+(4^2*0.0625)+(5^2*0.0625) - 1.9375^2)
√(5.1875 - 3.75390625)
√1.43359375
SD(X) = 1.197
SD(X) = 1.20
A computer game was originally priced at $59.99. It was marked down 15%. Then it was moved to a clearance rack marked "Take an additional 50% off the lowest marked price." What was the final price of the computer game?
Answer:
25.50 is the final price
Step-by-step explanation:
First find the new price at 15% off
59.99 * 15%
59.99 * .15
9.00
Subtract 9 dollars from the price
59.99-9.00
50.99
Now take 50% off
50.99 * 50%
50.99*.50
25.50
50.99-25.50
25.50

Leslie tunes a guitar with 6 strings and a piano with 37 times as many strings.
How many strings did the piano have?
Choose 1 answer:
(Choice A)
The piano has 422 strings, because 37×6=422.
(Choice B)
The piano has 222 strings, because 37×6=222.
(Choice C)
The piano has 6 strings, because 37÷6=6 remainder 1.
23) When a two digits number is divided by the sum of its digits, then the
quotient is 8 and the remainder is 2. If the digits are reversed and the
resulting number so formed is divided by the sum of the digits, the
quotient is 2 and the remainder is 8. Find the two digits number.
Answer: 82
Step-by-step explanation:
As we know remainder formula:-
Dividend = Quotient × Divisor + Remainder
Here, dividend = Two digits number & divisor = Sum of digits
m + 10n = 8 × (m + n) + 2
m + 10n = 8m + 8n + 2
m - 8m + 10n - 8n = 2
2n - 7m = 2
2n = 7m + 2
n = (7m + 2)/2 - - (Eq.1)
Digits interchanged, two digits number is divided by sum of digits, quotient is 2 & remainder is 8.
Now, when digits interchanged:-
Two digits number = 10m + n
Using same formula we get:-
10m + n = 2 × (m + n) + 8
10m + n = 2m + 2n + 8
10m - 2m + n - 2n = 8
8m - n = 8
8m = n + 8
n = 8m - 8 - - - (Eq.2)
Comparing both equations:-
(7m + 2)/2 = 8m - 8
7m + 2 = 2(8m - 8)
7m + 2 = 16m - 16
7m - 16m = -16 - 2
-9m = -18
m = -18/-9
m = 2
So, digit at unit's place = 2
Put this value in (Eq.2)
n = 8(2) - 8
n = 16 - 8
n = 8
So, digit at ten's place = 8
Now two digit number:-
Two digit number = 2 + 10(8)
Two digit number = 2 + 80
Two digit number = 82

Find the range of values for which
x2–5x + 6 < 0
Answer:
Step-by-step explanation:
x^2 - 5x + 6 = 0
(x - 2)(x - 3)
So the critical point are x = 2 and x = 3.
The graph of the function opens upwards and pass through the x axis at (2, 0) and (3, 0).
So the required range is the values of f(x) between when x = 2 and x = 3
that is 2 < x < 3.
Answer:
Step-by-step explanation:
1 Factor {x}^{2}-5x+6x
2
−5x+6.
(x-3)(x-2)<0
(x−3)(x−2)<0
2 Solve for xx.
x=3,2
x=3,2
3 From the values of xx above, we have these 3 intervals to test.
\begin{aligned}&x<2\\&2<x<3\\&x>3\end{aligned}
x<2
2<x<3
x>3
4 Pick a test point for each interval.
For the interval x<2x<2:
Let's pick x=0x=0. Then, {0}^{2}-5\times 0+6<00
2
−5×0+6<0.
After simplifying, we get 6<06<0, which is false.
Drop this interval..
For the interval 2<x<32<x<3:
Let's pick x=\frac{5}{2}x=
25
. Then, {(\frac{5}{2})}^{2}-5\times \frac{5}{2}+6<0( 25) 2−5× 25+6<0.
After simplifying, we get -0.25<0−0.25<0, which is true.
Keep this interval..
For the interval x>3x>3:
Let's pick x=4x=4. Then, {4}^{2}-5\times 4+6<04 2 −5×4+6<0.
After simplifying, we get 2<02<0, which is false.
Drop this interval..
5 Therefore,
2<x<3
2<x<3
