9.05 as a improper fraction

Suppose that your statistics professor tells you that the scores on a midterm exam were approximately

DedPeter [7]

Answer:

Yes

Step-by-step explanation:

z-score representing 85% is 1.04 (from table)

Let x be the score representing the lower limit of 85%.

Use the formula to find z-scores:

z = (x - μ)/σ

We have:

z = 1.04, μ = 78, σ = 7

Substitute the values and solve for x:

1.04 = (x - 78)/7
x - 78 = 7.28
x = 85.28

The lower limit of the top 15% is 85.28.

Since your score is greater than 85.28 you earned an A

write an equation in standard form with integer coefficients for the line with slope 6/11 going through the point (-1,-6)

yKpoI14uk [10]

If the slope is 6/11 then, in y=mx+b form, m will be 6/11. When you multiply 6/11 and -1 you get -6/11. To get the y (-6), you have to add -60/11. So in, y=mx+b form the equation is y=6/11x+(-60/11). To make it standard form, you add negative 6/11x to both sides and then multiply by 11 to get rid of the fractions. So therefore the equation would be:

-6x + 11y = - 60

Step-by-step explanation:

First, identify your variables:

Let "l" represent the weight of one large box.

Let"s" represent the weight of one small box.

Then, stack the two equations on top of each other:
