Answer:

The correct option is C .

Step-by-step explanation:

A logarithm function is written in the form of  y=log_ax,

Since, y = 0.25x is the type of function y = mx + c,

Which is the general form of a linear function,

⇒ y = 0.25x is not a logarithm function,

y=x^{0.25} is the type of function y=kx^a, where k and a are any real number,

Which is the general form of a power function,

⇒ y=x^{0.25} is not a logarithmic function.

y=(0.25)^x is the type of function y=ab^x

Which is the general form of exponential function,

⇒ y=(0.25)^x is not a logarithmic function,

Hence, only the function in option C has written in the form of y=log_ax.

Option C is correct.

I think the answer is C, y= log 25^x. Logarithmic functions are inverses of exponential functions. the inverse of exponential function y =a ^x is x = a^y. The logarithmic function y = logaX, is defined to be equivalent to the exponential equation x= a^y.

x - 2y = 3 5x + 3y = 2 The lines whose equations are shown intersect at which point? (1, -1) (-1, 1) (0, 3/2)
gtnhenbr [62]
I would solve the first equation for x and then sub that value into x in the second equation.  That's the easiest way.  x - 2y = 3 solved for x is x = 2y+3.  Now sub that in for x in the second equation: 5(2y+3)+3y=2 and 10y + 15 + 3y = 2.  13y = -13, and y = -1.  Now sub that y value into either equation to solve for x: x = 2(-1) + 3 gives us an x value of x = 1.  Therefore, your solution to this system is (1, -1), first choice above.

Answer:

d. H0: melanoma mortality rate is not linearly related to latitude

   Ha: melanoma mortality rate is linearly related to latitude

Step-by-step explanation:

The linear regression equation is

y=α+βx where α=intercept and β=slope.

β=slope demonstrates the change in dependent variable due to unit change in independent variable.

If the slope is zero then we can say that Y and X are not linearly related.

Thus, the hypothesis for testing significance of linear relationship two variables can be written as

Null hypothesis: The two variables are not linearly related i.e. β=0

Alternative hypothesis : The two variables are linearly related i.e. β≠0.

Thus, in the given scenario the hypothesis are

H0: melanoma mortality rate is not linearly related to latitude

Ha: melanoma mortality rate is linearly related to latitude.
