What are the slope and the y-intercept of the linear function that is represented by the table?
x. y
-3/4. -1/30
-1/2. -2/15
1/4. -13/30
2/3. -3/5
a. the slope is -2/5 and the y intercept is -1/3
b.the slope is -1/3 and the y intercept is -2/5
c.the slope is 1/3 and the y intercept is -2/5
d.the slope is 2/5 and the y intercept is -1/3
Answer: a. the slope is -2/5 and the y-intercept is -1/3
Step-by-step explanation:
Find the slope by finding the difference in x-values divided by the difference in y-values
(1/4 ,-13/30) and (-3/4, -1/30) are useful values
-13/30 --1/30 = -12/30 = -2/5 is the rise
-1/4 - -3/4 = 1 is the run (-2/5)/1 Division by 1 leaves the original numerator)
the slope is -2/5
To find the y intrcept, substitute the y and x values from any given coordinate into the slope intercept form and solve for b
y= mx + b
-3/5 = (-2/5)(2/3) + b
-9/15 + 4/15 = b
-5/15 = b
-1/3 = b This is the y-intercept

EXPLAIN YOUR ANSWER
A clothing store owner decided to track customers' reasons for returning items. She found that 9% of customers do not provide a reason, 29% say the item did not fit, 13% find a flaw with the item and 4% changed their mind about the purchase. The remaining customers returns gifts purchased for them. What is the probability that out of 40 returns on a given day, 20 are gifts that are being returned?
Answer:
0.102542
Step-by-step explanation:
Given that 9% of customers do not provide a reason, 29% say the item did not fit, 13% find a flaw with the item, and 4% changed their mind about the purchase.
So, the total percentage of items returned due to no reason, unfit, flaw, and due to changing mind
=9%+29%+13%+4%=55%
As the remaining customers returned gifts purchased for them, so, the percentage of customers who returned gifts =100-55=45%.
So, the fraction of customers who returned gifts=45/100=0.45.
Now, observe that if 1 item returned, there is a chance of 0.45 that the item is a gift.
Moreover, there are only two possibilities for any idem, i.e the idem was a gift or not a gift, so the number of total returned items can be considered a Bernoulli's population.
Let p be the probability of a returned item which is the same for all the returned items,
p=0.45
So, according to Bernoulli's theorem, the probability that out of n=40 returns on a given day, r=20 are gifts is
[tex]\binom{n}{r}p^r(1-p)^{n-r}=\binom{40}{20}(0.45)^{20}(1-0.45)^{40-20}[/tex]
[tex]=0.102542[/tex]
Hence, the probability that 20 returned items are gifts among the total 40 returned items is 0.102542.

If 1 foot ≈ 0.305 meter, approximately how many feet are in 8 meters? Round to the nearest tenth, if necessary.
Answer:
26.22 foot
Step-by-step explanation:
The relation between foot and meter is given by :
1 foot = 0.305 meter
We firstly find value of 1 meter in terms of foot.
So,
[tex]1\ m=\dfrac{1}{0.305 }\ \text{foot}[/tex]
To find no of foot in 8 meters, multiply [tex]\dfrac{1}{0.305 }[/tex] by 8 i.e.
[tex]8\ m=\dfrac{1}{0.305 }\times 8\ m\\\\=26.22\ \text{foot}[/tex]
So, there are 26.22 foot in 8 meters.

Answer: 32
Step-by-step explanation:
This is an example of an arithmetic sequence as the difference between the first 3 terms is constant. We can see that 4 is constantly being subtracted.
[tex]a_{n}=a+(n-1)d[/tex] is the formula for an arithmetic sequence.
[tex]a_{n}[/tex] = nth term
a = the first term in the sequence
n = term you are looking for (in this case 45)
d = common difference between the terms (in this case -4)
∴
[tex]a_{n}=a+(n-1)d[/tex]
[tex]a_{45} =208+(45-1)(-4)\\a_{45}=32[/tex]

How many solutions and what type of solutions does a quadratic equation have if the value of the discriminant is a positive perfect
square?
2 rational solutions
2 irrational solutions
1 rational solution
O real solutions
Answer:
2 rational solutions
Step-by-step explanation:
the degree of the polynomial (the highest exponent of the variable) defines how many solutions there are.
that means for how many values of x the result y is 0 (how many x-axis interceptions there are or should be).
so, a quadratic equation has 2 such solutions.
there are a few different cases how these solutions present themselves :
"normal case" : all the solutions are real (not only rational) numbers, and the curve has that many different x- acid interceptions.
a turn of the curve leads to only "touching" the x-axis : this is just a special case that the curve is "too high" or "too low" and the regular 2 intersects merge into 1. there are formally still 2 solutions, but they are identical.
there can be "S-curves" especially for higher degrees (3 and up) with the center smoothing in with the x-axis : this is similar but can merge even more than 2 solutions into 1.
the curve is really "too high" or "too low" and never even touches the x-axis : then the solutions are irrational.
the general solution for a quadratic equation is
x = (-b ± sqrt(b² - 4ac))/(2a)
the discriminate is (b² - 4ac).
if this is a positive perfect square, then the square root is a perfect integer. in fact, 2 perfect integers (+ and -).
and so we get two solutions with integer/integer and they are therefore 2 rational solutions.
What is a fraction that is halfway in between 1/5 and 1/6?
I REALLY NEED HELP
Answer:
Step-by-step explanation:
Let's find the LCM of 5 and 6. 5x6 is 30. So 1/5 times 6 to both numerator and denominator is 6/30. 1/6 is slightly different. 30 is 5 times 6. So 1/6 times 5 to both denominator and numerator is 5/30. Since 6/30 and 5/30 does not have a halfway point, let's multiply both by 2. It is 10/60 and 12/60. Midway point is 12+10/2 which is 11/60.

EJERCICIOS: Resuelvan los problemas aplicando regla de tres en conversion de metros a varas A) Una mesa cuadrada mide 1.85 M de lado ¿ cuantas varas debe tener cada tabla de largo para fabricarla? B) Jose tiene un lote de 25 M de largo y 15 M de ancho ¿cuantas varas cuadradas tiene el terreno? Por favor ayuda es para ahorita si mo saben no contesten ok por favor gracias
Answer:
A) Se requiere una tabla con una longitud de 2.213 varas para fabricar la mesa.
B) El lote de José tiene una extensión de 536.481 varas cuadradas.
Step-by-step explanation:
A) La vara es una unidad de longitud equivalente a 0.836 metros. También sabemos que un cuadrado es una figura geométrica con cuatro lados de igual longitud y cuatro ángulos rectos, de modo que la longitud y ancho de la mesa es igual. Entonces, el largo de la tabla, esto es, la superficie superior de la mesa, tiene una medida de 1.85 metros.
A continuación, realizamos la regla de tres para determinar su equivalente en varas:
[tex]x = 1.85\,m\times\frac{1\,vara}{0.836\,m}[/tex]
[tex]x = 2.213\,varas[/tex]
Se requiere una tabla con una longitud de 2.213 varas para fabricar la mesa.
B) La vara es una unidad de longitud equivalente a 0.836 metros. Una vara cuadrada es una unidad de área y es igual a:
[tex]r = (0.836\,m)\cdot (0.836\,m)[/tex]
[tex]r = 0.699\,m^{2}[/tex]
De manera semejante, tenemos que el área del lote de Jose es un rectángulo y que se calcula como sigue en metros cuadrados:
[tex]A = l\cdot w[/tex] (Eq. 1)
Donde:
[tex]A[/tex] - Área del lote de José, medido en metros cuadrados.
[tex]l[/tex] - Largo del lote de José, medido en metros cuadrados.
[tex]w[/tex] - Ancho del lote de José, medido en metros cuadrados.
Si [tex]l = 25\,m[/tex] y [tex]w = 15\,m[/tex], entonces el área del lote es:
[tex]A = (25\,m)\cdot (15\,m)[/tex]
[tex]A = 375\,m^{2}[/tex]
Por último, hallamos el área en varas cuadradas mediante la siguiente regla de tres:
[tex]x = 375\,m^{2}\times \frac{1\,vara}{0.699\,m^{2}}[/tex]
[tex]x = 536.481\,varas^{2}[/tex]
El lote de José tiene una extensión de 536.481 varas cuadradas.

Step-by-step explanation:
Using the Sine rule in Δ TUV, that is
[tex]\frac{t}{sinT}[/tex] = [tex]\frac{u}{sinU}[/tex] , substitute values
[tex]\frac{2.5}{sin26}[/tex] = [tex]\frac{u}{sin85}[/tex] ( cross- multiply )
u × sin26° = 2.5 × sin85° ( divide both sides by sin26° )
u = [tex]\frac{2.5sin85}{sin26}[/tex] ≈ 5.7 ( to 1 dec. place )

Write an equation in point-slope form of the line that passes through the given point and has the given slope. (12, 5); m = -3
Answer:
y - 5 = -3(x - 12)
Step-by-step explanation:
Point slope form is: y - y1 = m(x - x1), where (x1, y1) is a point on the line, and m is the slope of the line.
Plug in the point and the slope:
y - y1 = m(x - x1)
y - 5 = -3(x - 12)
So, y - 5 = -3(x - 12) is the equation in point slope form of the line.
