<h2>x = 13</h2>

Step-by-step explanation:

\frac{2x + 1}{3}  =  \frac{x + 5}{2}  \\ 2(2x + 1) = 3(x + 5) \\  \:  \:  \:  \: 4x + 2 = 3x + 15 \\ 4x - 3x = 15 - 2 \:  \\  \:  \:  \: x = 13

Using the shortcut for binomial expansion, which still took 45 minutes, I got 23-26.  The coefficient on the x^6 term is 34,020; the coefficient on the x^4 term  is -495; on the x^7 term it's 1800; on the x^3 term it's 337,920.  I'm pooped.  The rest is factorial notation, kinda the same thing, but...

What is the equation of a line that passes through the points (-3, 4) and (2,8)?
ziro4ka [17]

Given that the line passes through the two points (-3,4) and (2,8)

We need to determine the equation of the line.

<u>Slope:</u>

The slope of the line can be determined using the formula,

m=\frac{y_2-y_1}{x_2-x_1}

Substituting the points (-3,4) and (2,8) in the above formula, we get;

m=\frac{8-4}{2+3}

m=\frac{4}{5}

Thus, the slope of the line is m=\frac{4}{5}

<u>Equation of the line:</u>

The equation of the line can be determined using the formula,

y-y_1=m(x-x_1)

Substituting the point (-3,4) and m=\frac{4}{5} in the above formula, we have;

y-4=\frac{4}{5}(x+3)

y-4=\frac{4}{5}x+\frac{12}{5}

     y=\frac{4}{5}x+\frac{12}{5}+4

     y=\frac{4}{5}x+\frac{32}{5}

Thus, the equation of the line is y=\frac{4}{5}x+\frac{32}{5}

Write the equation of the line from the given information. through (-3,5) &amp; (4,-2)
Masteriza [31]

Answer:

y = -x + 2

Step-by-step explanation:

(-3,5) and (4,-2)

Slope: (-2-5)/(4 - - 3) = -7/7 = -1

y-intercept= -2 - (-1)(4) = -2 + 4 = 2

When sample size increases Group of answer choices
Olenka [21]

Answer:

Option A)

Confidence interval decreases

Step-by-step explanation:

If we increase the sample size, then,

  • The standard error of the interval decrease.
  • If the standard error increase, the margin of error of the interval decrease.
  • If the margin of error decreases, the width of the confidence level decreases, hence, the confidence interval become narrower.

Thus, the correct answer is

Option A)

Confidence interval decreases
