Find x of the triangle
sukhopar [10]

Answer:

Step-by-step explanation:

altitude = sqrt(6*8) = 4*sqrt(3)

Use the Pythagorean Theorem to derive x

altitude^2 + 18^2 = x^2

48 + 18^2 = x^2

x^2 = 342

x = 3*sqrt(38)

x = 18.49

the ratio of peters money to henrys money is 4 : 3 there at first. after perter spent 12 dollars they had an equal amount of mon
MatroZZZ [7]

Using a system of equations, it is found that Peter had $48 at first.

<h3>What is a system of equations?</h3>

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

In this problem, the variables are:

  • Variable x: Peter's money.
  • Variable y: Henry's money.

The ratio of peters money to henrys money is 4 : 3, hence:

\frac{x}{y} = \frac{4}{3}

After Peter spent $12, they had the same amount, hence:

y = x - 12.

Then, replacing in the ratio:

\frac{x}{y} = \frac{4}{3}

\frac{x}{x - 12} = \frac{4}{3}

4(x - 12) = 3x

x = 48.

An international polling agency estimates that 36 percent of adults from Country X were first married between the ages of 18 and
alukav5142 [94]

Answer:

(B) 0.2843

Step-by-step explanation:

Let d be the difference in proportions from Country X and Country Y who were first married between the ages of 18 and 32.

Then hypotheses are

H_{0}: d=0.15

H_{a}: d<0.15

Test statistic can be found using the equation

z=\frac{p1-p2-0.15}{\sqrt{{p*(1-p)*(\frac{1}{n1} +\frac{1}{n2}) }}} where

  • p1 is the sample proportion of Country X (0.36)
  • p2 is the sample proportion of Country Y (0.26)
  • p is the pool proportion of p1 and p2 (\frac{60*0.36+50*0.26}{50+60}=0.31)
  • n1 is the sample size of adults from Country X (60)
  • n2 is the sample size of adults from Country Y (50)

Then z=\frac{0.36-0.26-0.15}{\sqrt{{0.31*0.69*(\frac{1}{60} +\frac{1}{50}) }}} ≈ 0.5646

p-value of test statistic is ≈ 0.2843

p-value states the probability that the difference in proportions between a random sample of 60 adults from Country X and a random sample of 50 adults from Country Y who were first married between the ages of 18 and 32 is at least 0.15
