ANSWER

x = 1.6

EXPLANATION

The given equation is:

- 0.5x - 2 = 2x - 1 - 6

Group similar terms to obtain:

- 0.5x - 2x =  - 5 - 1 + 2

Simplify similar terms,

- 2.5x =  - 4

Divide both sides by -2.5

x =  \frac{ - 4}{ - 2.5}

x = 1.6

What is the graph of the rational function? Y=-3x+5/-5x+2
Natalija [7]

Answer:

See attached picture.

Step-by-step explanation:

Find critical points to graph the rational function.

When x = 0, then y = 5 / 2 = 2.5.

When y=0, then 0=-3x+5 and x= 5/3 =1.6667.

Plot the points (0,2.5) and (1.6667, 0). Then draw the "L" shape graphs of the rational function.

To assess the precision of a laboratory scale, we measure a block known to have a mass of 1 gram. we measure the block n times a
vlada-n [284]
<span>n = 5 The formula for the confidence interval (CI) is CI = m ± z*d/sqrt(n) where CI = confidence interval m = mean z = z value in standard normal table for desired confidence n = number of samples Since we want a 95% confidence interval, we need to divide that in half to get 95/2 = 47.5 Looking up 0.475 in a standard normal table gives us a z value of 1.96 Since we want the margin of error to be ± 0.0001, we want the expression ± z*d/sqrt(n) to also be ± 0.0001. And to simplify things, we can omit the ± and use the formula 0.0001 = z*d/sqrt(n) Substitute the value z that we looked up, and get 0.0001 = 1.96*d/sqrt(n) Substitute the standard deviation that we were given and 0.0001 = 1.96*0.001/sqrt(n) 0.0001 = 0.00196/sqrt(n) Solve for n 0.0001*sqrt(n) = 0.00196 sqrt(n) = 19.6 n = 4.427188724 Since you can't have a fractional value for n, then n should be at least 5 for a 95% confidence interval that the measured mean is within 0.0001 grams of the correct mass.</span>
