An evaluation of the habitats of endangered salmon species was performed in Conservation Ecology (December 2003). The researcher

s identified 734 sites (habitats) for Chinook, coho, or steelhead salmon species in Oregon and assigned a habitat quality score to each site. (Scores range from 0 to 36 points, with lower scores indicating poorly maintained or degraded habitats.) The data are saved in the HABITAT file. Give your opinion on whether the habitat quality score is normally distributed.

X + 3 = -1 Prove x<br> Need help I need to see work. Don’t understand this problem.
raketka [301]

Answer:

x=-4

Step-by-step explanation:

X needs to be a number that when 3 is added to it, becomes -1. So, adding 3 to -4 gives you -1, therefore, x=-4. Hope this helped!

f(x)=4 hallar el dominio, codominio, ceros o raices, vertices, asintotas, tabla de valores, graficas, identificar el tipo de fun
nekit [7.7K]

Answer:

Tipo de función: Función Constante o Función Polinómica de Orden Cero

Dominio: Dom \{f(x)\} = \mathbb{R}

Codominio: Ran \{f(x)\} = 4

Asíntota: y = 4

Raíces: No tiene.

Vértices: No tiene.

La tabla de valores y el gráfico se encuentran adjuntos al fondo.

Step-by-step explanation:

Sea f(x) = 4, el cual representa a una Función Constante o Función Polinómica de Orden Cero, cuyos dominio y codominio son Dom \{f(x)\} = \mathbb{R} y Ran \{f(x)\} = 4. No tiene vértices. Esta función tiene una asíntota horizontal coincidente con la función (y = 4) y carece de raíces al ser f(x) \ne 0 para todo x\in \mathbb{R}.

Finalmente, agregamos una tabla de valores y la gráfica asociada a la función:

x         -2         -1         0         1          2

y         4          4         4         4         4

Finger [1]

Answer:

15 sqrt 2

Step-by-step explanation:

Use Pythagorean Theorem

a^2 + b^2 = c^2

15^2 + 15^2 = c^2

225 + 225 = 450

Find prime factors of the sq rt of 450

450 = 2 * 3 * 3 * 5 * 5

15 sqrt 2

Marta wrote six and eighty hundredths. Nicky wrote six and eight tenths. Who wrote the greater number? explain
nataly862011 [7]
The numbers are both equal because, 6.80 is six and eight hundredths, and 6.8 is six and eight tenths. When writing decimals any zero added to the end of the number has no value, 8/10 as a fraction is equal to 80/100 if simplified, so Nicky and Marta wrote equal numbers. :)
