Halle la ecuación del eje x y la ecuación del eje y, usando dos puntos que se encuentren sobre los mismos.

lisov135 [29]

Una linea recta ( cualquier eje coordenado es una línea recta) queda definida si se conocen dos puntos que están sobre ella.

Solución:

Ecuación del eje x y = 0

Ecuación del eje y x = 0

Para darle respuesta a la pregunta podemos seguir el siguiente procedimiento:

Escogemos dos puntos arbitrarios sobre el eje x, por ejemplo

P ( 2 ; 0 ) y Q ( 5 ; 0 ) ( todos los puntos sobre el eje x tienen coordenada y = 0.

Según la cual m = (y₂ - y₁)/ ( x₂ - x₁ ) m = 0

Usamos la ecuación pendiente-Intercepto

y = m×x + b donde m es la pendiente y b el intercepto con el eje y

y entonces tenemos:

m = 0 b ( 0 ; 0 )
Por sustitución en la ecuación pendiente-intercepto

y = 0

Procediendo de forma similar obtendremos la ecuación del eje y

P´( 0 ; 4 ) Q´( 0 : 8 ) entonces

y = m×x + b

En este caso, la pendiente no es definida ( tang 90° ) y b es de nuevo el punto b ( 0 ; 0).

A partir de que todos y cada uno de los puntos sobre el eje y son de valor 0 para x, concluímos que ecuación del eje y es

x = 0

5. A survey of student pizza preferences showed that 43 students preferred cheese, 56 preferred sausage, 39 preferred pepperoni,

cestrela7 [59]

Answer:

P (Cheese) = 0.199, P (Sausage) = 0.259, P (Pepperoni) = 0.181,

P (Supreme) = 0.130, P (Another Kind) = 0.144

and P (Does not like any kind) = 0.088

Step-by-step explanation:

Given:

Number of students who prefer cheese = 43

Number of students who prefer sausage = 56

Number of students who prefer pepperoni = 39

Number of students who prefer supreme = 28

Number of students who prefer another kind = 31

Number of students who did not like any kind = 19

∴ The total number of students surveyed = $43+56+39+28+31+19=216$ The number of students who prefer pizza = $43+56+39+28+31=197$

The probability that a students likes pizza is,

$P(Student\ likes\ pizza)=\frac{No.\ of\ students\ who\ prefer\ pizza}{Total\ no.\ of\ students\ surveyed}$

$=\frac{197}{216} \\=0.912$

The probability that a students does not likes pizza is,

$P(Student\ does\ not\ likes\ pizza)=\frac{No.\ of\ students\ who\ does\ not\ prefer\ pizza}{Total\ no.\ of\ students\ surveyed}$

$=\frac{19}{216} \\=0.088$

The probability distribution of students who prefer different kinds of pizza is:

The probability that a student likes cheese:

$P(A\ Student\ prefers\ cheese)=\frac{No.\ of\ students\ who\ prefer\ cheese}{Total\ no.\ of\ students\ surveyed}$

$=\frac{43}{216}\\=0.199$

The probability that a student likes sausage:

$P(A\ Student\ prefers\ sausage)=\frac{No.\ of\ students\ who\ prefer\ sausage}{Total\ no.\ of\ students\ surveyed}$

$=\frac{56}{216}\\=0.259$

The probability that a student likes pepperoni:

$P(A\ Student\ prefers\ pepperoni)=\frac{No.\ of\ students\ who\ prefer\ pepperoni}{Total\ no.\ of\ students\ surveyed}$

$=\frac{39}{216}\\=0.181$

The probability that a student likes supreme:

$P(A\ Student\ prefers\ supreme)=\frac{No.\ of\ students\ who\ prefer\ supreme}{Total\ no.\ of\ students\ surveyed}$

$=\frac{28}{216}\\=0.130$

The probability that a student likes another kind:

$P(A\ Student\ prefers\ another\ kind)=\frac{No.\ of\ students\ who\ prefer\ another\ kind}{Total\ no.\ of\ students\ surveyed}$

$=\frac{31}{216}\\=0.144$

Thus, the probability distribution table is displayed below:

I’m not sure how to do solving and graphing inequalities

Juliette [100K]

Answer:

its easy

Step-by-step explanation:

First you need to get your two numbers or more than to like for example 6 and 9 6<9 the alligator mouth would go to the 9 because its bigger and say for instances 9,10,5 it would be 9<10>5 ten is bigger than them all so there you go

Deena drive 585 miles in 9 hours Kristen drove 605 in 11 hours who drove the faster rate

Lady bird [3.3K]

Deena drove:
585 miles/9 hrs
....which means
her average rate was:
65miles/hour

whereas

Kristen drove:
605 miles/11 hrs
....meaning
her average rate was:
55 miles/hour

Therefore, Deena drove at a faster rate than Kristen
