Answer:

y=t/(12dt+19)

Step-by-step explanation:

This question want us to make y the subject of formula...it involves a step by step process

Back to the question

12ytd=-19y+t

Let's start solving by asking how can we make y the subject of formula from this equation...you have to be a fast thinker

Let's continue with the solution

12ytd=-19y+t

Add 19y to both sides

12ydt+19y=t

Then factorise only from the left side and y is common to the two figures

y(12dt+19)=t

Divide both sides by (12dt+19)

y=t/(12dt+19)

Therefore the final answer is y=t/(12dt+19)

The scores on a test are normally distributed with a mean of 78 and a standard deviation of 13. Find the score that is 2 standar

Veronika [31]

Answer:

Step-by-step explanation:

Given that :

Mean (m) = 78

Standard deviation (s) = 13

Score that is 2 standard deviations below the mean

Using the relation :

Zscore = (x - m) / s

2 standard deviations below the mean means a Zscore of - 2

Hence,

-2 = (x - 78) / 13

Cross multiply

-2 * 13 = x - 78

-26 = x - 78

x = - 26 + 78

x = 52

Score which is 2 standard deviations below the mean is 52

Find the derivative of f(x) = negative 9 divided by x at x = -4. (6 points) 4 divided by 9 16 divided by 9 9 divided by 16 9 div

Len [333]

Answer:

9/16

Step-by-step explanation:

$f(x)=-\frac{9}{x}$

$f(x)=-9x^{-1}$

Derivative rule:

$f(x)=x^{n} \\$

$\frac{df}{dx}=nx^{n-1}$

Here, n=-1, so

$\frac{df}{dx}=(-9)(-1)x^{-2} =\frac{9}{x^{2} }$

Evaluating this at x=-4 gives 9/16
