Solve for y,

13x - 11 y = -12

13x + 12 = 11y

Determine the quotient: (22.8 × 10–3) ÷ (5.7 × 10–6)
lana66690 [7]

Answer:

0.399

Step-by-step explanation:

The key to doing this problem properly lies in knowing and following order of operations rules.

Here we must perform mult. and div.  before  addition and subtr., but even before that we must do all work enclosed in parentheses first.

(22.8 × 10–3) is evaluated by doing the mult. first, and then subtracting 3:

(228-3) = 225

and

(5.7 × 10–6) is evaluated by doing the mult. first, then subtracting 6:

(570-6) = 564.

Finally, we divide 225 by 564, obtaining 0.399 (after rounding off to three decimal places).

For which of the following sets of data should a stacked bar chart be used? A. The average height of men vs. the average height
Kobotan [32]

Answer:

C. The total number of movies watched categorized by science fiction vs. non-science fiction

Step-by-step explanation:

A stacked bar chart is a type of graph that is mostly used to simplify multiple parts and compare them as a whole.

It uses different "bars" and each bar represents one part of the whole and segments of that bar show the different parts or categories of the whole.

Consider option A

In this option, the total average height of men and women cannot be considered as a whole. Therefore, the stacked chart cannot be used.

Consider option B

In this option, the totak number of red cars and bicycles cannot be considered as a whole because cars and bicycles are two different kinds of sets.

Consider option C

Here, the total number of movies watched categorized by science fiction and non-science fiction can be considered a whole because science and non-science fiction movies are the same sets of data and they add up to the total number of movies.

Hence, a stacked graph is appropriate here.

Option C is the correct answer

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!

Fantasty-N-Fun sells gaming cards for $9.99 but they pay only $6.75 per card. What is the percent markup
Sliva [168]
100%=9.99
×%=6.75

9.99x=100×6.75
9.99X=675

X=675/9.99
67.567% or 67.57

you could also say:

6.75/9.99=0.67567

0.67567×100=67.57%

so the markup is 100%-67.57%=32.43%

32.43%off
