A= h (a+b)


solving for b:

Solve for b, i.e separate b in one side and the other terms in the other side

A = ah + bh


A - ah = bh

(A - ah) / h = b

b= \frac{A-ah}{h}



I hope that helps!

the correlation between two variables related to the same sample is a scaled quantitative measure. what is used to scale this me
Doss [256]

The correct option is the standard deviations of the variables.

What is correlation?

Any statistical relationship between two random variables or bivariate data, whether causal or not, is referred to in statistics as correlation or dependence.

Correlation is a term used to describe the linear relationship between two entities. When using a correlation tool, the variables must be present in quantities of two or more to test their relationship (degree of association).

In order to scale the measurement between two variables connected to a similar sample, the standard deviation measures dispersion.

The variables' standard deviations are the best choice as a result.

Option involving the standard errors of the variables is incorrect because standard error, which stands for standard deviation, determines the relationship between dependent and independent variables.

Option involving the coefficients of variation of two variables is incorrect because the coefficient expressing standard deviation and mean ratio determines how much variation there is.

Option The means of the variables are incorrect because they are not a scale for determining the correlation between two variables.

Hence, the correct option is the standard deviations of the variables.

Minerva starts a savings account with $50. The interest on the account balance is compounded annually. The graph below shows the
rodikova [14]

We can set up this equation using this formula:

a = p(1 + r/n)^nt

p = starting amount.

r = interest.

n = number of times it's compounded in a year

t = years

We'd set it up like this:

a = 50(1 + ?/1)^1(12)

Because we're missing the amount of interest, it would be impossible to tell what the amount would be after 12 years.

Write an equation in point-slope form of the line that passes through the given point and with the given slope m.
il63 [147K]

y = mx + c

7 = 4(-8) + c

c = 39

The equation is y = 4x + 39

y - 7 = 4 ( x - (-8))

y -7 = 4 (x +8)
