Answer:

atleast 12

Step-by-step explanation:

someone donated $10, you use the $10 to buy 5 cakes

the profit is $50

you still need 50 more

10-2= $8 in profits

50/8= 6.25 cakes

5 + 6.25 = 11.25

<u>or atleast 13 if you don't count the $10 in</u>

Answer:

P(52

And we can find this probability with this difference:

P(-0.851

And if we use the normal standard distribution or excel we got:

P(-0.851

Step-by-step explanation:

Let X the random variable that represent the time required to construct and test a particular component of a population, and for this case we know the distribution for X is given by:

X \sim N(60,9.4)  

Where \mu=60 and \sigma=9.4

We want to find this probability:

P(52

And the best way to solve this problem is using the normal standard distribution and the z score given by:

z=\frac{x-\mu}{\sigma}

Using this formula we got:

P(52

And we can find this probability with this difference:

P(-0.851

And if we use the normal standard distribution or excel we got:

P(-0.851

Listed below is data on profit and market capitalization for a sample of 15 different firms in U.S. Profit is the y variable and
MissTica

Answer:

Step-by-step explanation:

Hello!

You have two study variables:

Dependent variable

Y: Profit of the firm in the U.S.

Independent variable

X: Market capitalization of the firm

a.

See the scatterplot in the attachment.

Looking at the graphic it seems that there is a positive regression between the profit and the market capitalization, meaning that every time the market capitalization of the firm increases, the profit of this firm also increases. But not all the "firms" adjust linearly, so I wouldn't expect the regression to be powerful.

b.

The regression model is E(Yi)= α + βXi

Where the parameters of the model are α and β, these two parameters are to be estimated to estimate the regression equation. The estimator for α is a and the estimator for β is b:

a= Y[bar] - bX[bar]

b= [∑XY-(∑X*∑Y)/n]/[∑X²-(∑X)²/n]

I'll use a statistic software to calculate the estimated regression equation:

^Yi= a + bXi

^Yi= 325.89 + 0.07Xi

c.

You need to predict the value of Y (Profit) given a value of X= 70721.3 (million). To make this prediction you have to use the estimated equation:

^Yi= 325.89 + 0.07Xi

^Yi= 325.89 + 0.07(70721.3)= 5276.381

The predicted profit for a market capitalization value of 70,721.3 is 5276.381 million.

I hope this helps!

Which expression is equivalent to the expression shown (5^3)^9 divides by 5 ^12
OleMash [197]

Answer:

5^15

Step-by-step explanation:

(5^3)^9

--------------

5^12

Power to a power means multiply

5^3^9 means 5^(3*9) = 5^27

5^27

----------

5^12

Division with the same base means subtract the exponents

5^(27-12)

5^15
