Verify that -8+ (-11)/(-12) = (-11)/(-12)+ (-8)

No The equation -8+(-11)/-12=(-11)/(-12)+(-8) do not equal each other. No matter how you look at it, the will never equal each other here’s some work if you need it :)


-8+(-11) = -19
Then the equation would look like this :)

-19 / -12 = (-11)/(-12)+(-8)

Now the other side :)

-12 +(-8)= -20

Leaving the equation looking as so

-19 / -12 = -11 / -20


They don’t look the same, you wouldn’t even need to solve that to know that they are not equivalent :) but if you did it would look like this :)


1.583(in repeating) = 0.55

Even so they are still not equivalent :)


Hope this helped you!! :)) have a nice day!

Differentiate each of the following, where
ankoles [38]

Answer:

\frac{\textbf{dy}}{\textbf{dx}} = \textbf{10ax}+\textbf{9bx}^2

Step-by-step explanation:

Let

y= 5ax^2+3bx^3+5

Differentiating y with respect to x

\frac{dy}{dx} =5a(2x)+3b(3x^2)+0

\frac{dy}{dx}= 10ax+9bx^2    where a and b are constants

A fair coin is tossed four times, and each time the coin lands heads up. if the coin is then tossed 1996 more times, how many he
andrey2020 [161]

Answer:

998 heads are likely to appear

Step-by-step explanation:

When a fair coin is tossed, the probability to flip a head is 50% and to flip a tail is also 50%, so if the coin is tossed 1996 times, 0.5*1996 = 998 heads and 998 tails are likely to appear, despite the fact the coin lands heads up 4 times before, because every toss is independent of the other ones.

A recent study by a major financial investment company was interested in determining whether the annual percentage change in sto
PolarNik [594]

Answer:

c. y? =+4.198 x

Step-by-step explanation:

Hello!

Using the given data you need to estimate the equation of linear regression.

Dependent variable:

Y: Annual percentage change in stock price for a company.

Independent variable:

X: Annual percentage change in profits for the company.

The population regression line equation is:

Y_i= \alpha + \beta X_i + E_i

To estimate the equation you need to find the point estimator for α and β.

The following formulas are the ones to use:

α ⇒ a= y[bar] - bX[bar]

β ⇒ b= (∑xy - [(∑x)(∑y)]/n)/(∑X²-(∑x)²/n)

As you can see you need to make several summatories before calculating the values of a and b:

n= 7

∑x= 36.30

∑x²= 667.09

∑y= 51.60

∑y²= 747.98

∑xy= 560.74

Sample mean of de dependent variable Y[bar]= ∑y/n= (51.60/7)= 7.37

Sample mean of the independent variable X[bar]= ∑x/n= (36.30/7)= 5.19

b= \frac{560.74-\frac{(36.3*51.6)}{7} }{667.09-\frac{(51.60)^2}{7} }

b= 0.6122

a= 7.37-(0.61*5.19)

a= 4.196

The estimated regression equation is:

Y= 4.196 + 0.6122x

I hope it helps!
