PLEASE HELP!!!

Answer:

The value of g(-1) is -2

Step-by-step explanation:

g(x) = 2x^4 + 3x^3 - x^2

Now we find g(-1)

To find g(-1) plug in -1 for x  in the given g(x) equation

Replace all x by -1

g(x) = 2x^4 + 3x^3 - x^2

g(x) = 2(-1)^4 + 3(-1)^3 - (-1)^2

g(x) = 2-3-1=-2

The value of g(-1) is -2

Is 1/8 - 10(3/4-3/8x)+5/8x equivalent to -1/8(59-35x)
madreJ [45]

Answer:

Yes

Step-by-step explanation:

1/8-10(3/4-3/8x)+5/8x

1/8-(30/4-30/8x)+5/8x

1/8-30/4+30/8x+5/8x

Lcm is 8

1-60+30x+5x/8

-59+35x/8

Factorise

-1/8(59-35x)

So when comparing the two,they are observed to be the same

Explain how to determine whether a sample correlation coefficient indicates that the population correlation coefficient is signi
NeX [460]

The population correlation coefficient is significant if the correlation is closer to 1, less significant is closer to zero, and not significant at all if the correlation coefficient is zero.

  • Correlation coefficients are used in determining the significance of a population and the strength of the relationship <u>between two variables. </u>

  • This relationship can either be strong, weak, or not exist.

  • The correlation coefficient can have values between 0 and 1 inclusive.  The population correlation coefficient is significant if the correlation is closer to 1, less significant is closer to zero, and not significant at all if the correlation coefficient is zero.
