Answer:

answer: 18

Step-by-step explanation:

Hello to find area in triangle you just have to do...

base × height ÷ 2 = area So our base is 3 and our height is 12 so 3 × 12 = 36 then 36 ÷ 2 = 18 Hope that helps!

For the​ following, indicate whether a confidence interval for a proportion or mean should be constructed to estimate the variab
anzhelika [568]

Answer:

A confidence interval for a mean should be constructed to estimate the variable of interest.

Step-by-step explanation:

The confidence interval for a mean uses the sample mean to estimate the true population mean.  Since it is a confidence interval, instead of a single number for the mean, the result shows a lower estimate and an upper estimate of the mean.  In this experiment, the confidence interval cannot be for a proportion since the population of healthy males is unknown, but the calculation is being done with a sample of 75 healthy males.

Step-by-step explanation:

<u>Step 1: Define</u>

\displaystyle ln(x^2) = -2

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Raise both sides by e:                    e^{\displaystyle ln(x^2)} = e^{-2}
  2. Simplify equation:                           x^2 = e^{-2}
  3. Square root both sides:                 x = \pm e^{-1}

An artist wants to frame a square painting with an area of 400 square inches. She wants to know the length of the wood trim that
Maurinko [17]
Area=legnth times width

if legnth=x
and
area=400

400=x times width

wait
SQUARE painting
legnth=width
width=x

400=x times x
400=x^2
sqrt both sides
20=x
answer is 20 in

equation is
400=x times x

Find (F/g)(x)<br> F(x) = sqrt x^2-1<br> g(x) sqrt x-1
Margaret [11]

Answer:

Option A. √(x + 1)

Step-by-step explanation:

Data obtained from the question include:

f(x) = √(x² – 1)

g(x) = √(x – 1)

(f/g) (x) =..?

(x² – 1) => difference of two square

(x² – 1) => (x – 1)(x + 1)

f(x) = √(x² – 1)

f(x) = √(x – 1)(x + 1)

(f/g) (x) = f(x) /g(x)

f(x) = √(x – 1)(x + 1)

g(x) = √(x – 1)

(f/g) (x) = √(x – 1)(x + 1) / √(x – 1)

(f/g) (x) = √[(x – 1)(x + 1) / (x – 1)]

(f/g) (x) = √(x + 1)
