8n-(2n-3)=12
8n-2n+3=12
6n+3=12
subtract 3 from both sides.
6n=9
divide 6 from both sides.
n=9/6 or 1.5

check your answer:
8n-(2n-3)=12
8(1.5)-(2(1.5)-3)=12
12-(3-3)=12
12-0=12
12=12

hope this helps.

A random sample of CO2 levels in a school has a sample mean of x¯=598.4 ppm and sample standard deviation of s=86.7 ppm. Use the
astraxan [27]

Answer:

99.7%

Step-by-step explanation:

we start by getting the z-scores for the values given

We can get the z-scores using the formula below;

z-scores = (x-mean)/SD

for 338.5;

z = (338.5-598.4)/86.7 = -2.99 approximately-3

for 858.5;

z = (858.5-598.4)/86.7 = 3

so we want to get the percentages that lie within 3 standard deviations from the mean

According to the empirical rule, the percentages within 3 SD of the mean is;

100-0.15-0.15 = 99.7%

The graph box linear function f passes through the point (1, -9) and has a slope of 3
Marat540 [252]

9514 1404 393

Answer:

  C) 4

Step-by-step explanation:

The point-slope equation of the line is ...

  y -k = m(x -h) . . . . . line with slope m through point (h, k)

  y +9 = 3(x -1) . . . . . line with slope 3 through point (1, -9)

For y=0 (the 0 of the function), we have ...

  9 = 3(x -1)

  3 = x -1

  4 = x

The x-intercept is (4, 0).

The lines graphed below are parallel. The slope of the red line is 2/5. What is the slope of the green line?
Naily [24]

Answer:

slope = 2/5

Step-by-step explanation:

The slope of the green line would also be 2/5 because in a graph where the lines are parallel, they always have the same slope, since the lines that are graphed are parallel, the slope of the green line will be the same as the slope of the red line.
