9x² + 12x - 6 = x² - 7
Take the ones on the right to the left

9x² - x² + 12x -6 + 7 = 0

8x² + 12x + 1 = 0

Directions- Write a formula from the given day for each linear function Find the equation of the line parallel to 6x+3y-11=0, th

lukranit [14]

Answer:

y = -3x-1 or 3x + y = -1

Step-by-step explanation:

6x + 3y - 11 = 0 can be written as y = -3x + (11/3)

In parallel lines the slope remains the same but the constant changes. To find the constant you place in the cordinates for x and y.

5 = -3(-2) + b

5 = 6 + b

5 - 6 = b

-1 = b

Now you replace (11/3) by the new b, -1

y = -3x - 1

Answer:

28 numbers

Step-by-step explanation:

There is a distance of 81 between -0.5 and 80.5. Divide this number by 3, since you are only counting every third number and you will get 27, but you need to count the first number, which has been excluded. Add one more to get the answer, 28.

Major league baseball salaries averaged $1.5 million with a standard deviation of $0.8 million in 1994. suppose a sample of 100

seropon [69]

Answer: The probability that the avg. salary of the 100 players exceeded $1 million is approximately 1.

Explanation:

Step 1: Estimate the standard error. Standard error can be calcualted by dividing the standard deviation by the square root of the sample size:

$SE=\frac{0.8}{\sqrt{100}}=\frac{0.8}{10} = 0.08$

So, Standard Error is 0.08 million or $80,000.

Step 2: Next, estimate the mean is how many standard errors below the population mean $1 million.

$\frac{1 - 1.5}{0.08}$

$=-6.250$

-6.250 means that $1 million is siz standard errors away from the mean. Since, the value is too far from the bell-shaped normal distribution curve that nearly 100% of the values are greater than it.

Therefore, we can say that because 100% values are greater than it, probability that the avg. salary of the 100 players exceeded $1 million is approximately 1.

[ Answer ]

$\boxed{\bold{LCM \ = \ 26}}$

[ Explanation ]

Find LCM For 2 & 13

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

LCM - The smallest number that two or more numbers can evenly fit into

LCM - What We Know
2 & 13 Must Evenly Fit
Must Be Smallest Number They Both Fit Into
Multiple Of Two Or More Numbers

The Smallest Number That Both 2 & 13 Evenly Fit Into Is 26

26 ÷ 2 = 13

26 ÷ 13 = 2

$\boxed{\bold{[] \ Eclipsed \ []}}$
