Answer:

32%

Step-by-step explanation:

Imagine 100000 people are tested.  

<u>Of these 100000:</u>

  • 10000080.02= 2000 will have the disease

<u>8% of them:</u>

  • 2000*0.08= or 160, will test negative and the remaining
  • 1840 will test positive.  

<u>Of the 98000 who do not have the disease, 4% will test positive:</u>

  • 98000*0.04= 3920 will test positive

<u>So of the:</u>

  • 1840+3920= 5760 total people who test positive,
  • 1840 will have the disease

<u>Thus, the probability is: </u>

  • 1840/​5760 ​​ ≈0.3194 = 32%

So, out of people who test positive actually 32% has the disease.

$1.12 for 8.2 ounces? Unit Rate
Reil [10]
That is around 13 or 14 cents. The specific answer is 13.65853659 cents, but you can either round up to 14 or round down to 13 (rounding up to 14 is the correct way to do it.)

First you divide 1.12 by 8.2 to get the unit rate because It takes $1.12 to buy 8.2 ounces. 1.12/8.2=13.65853659

Find two constructive odd integers who sum is 36
Alex

Two consecutive odd integers with a sum of 36 are 17 and 19.

To find these integers, we start by using the definition of consecutive odd integers to represent our consecutive odd integers as n and n + 2. Now, we can set up an equation using the fact that the sum of these two integers is equal to 36.

n + (n + 2) = 36

Solving this equation for n will give us the first of our consecutive odd integers that sum to 36.

n + (n + 2) = 36

Simplify the left-hand side.

2n + 2 = 36

Subtract 2 from both sides of the equation.

2n = 34

Divide both sides of the equation by 2.

n = 17

We get that the first of the two consecutive odd integers is 17, so the second one is 17 + 2, or 19. Therefore, we find that two consecutive odd integers whose sum is 36 are 17 and 19.h

If ∆ABC = ∆EDF where the coordinates of A(0,2), B(2,4), and C(2,-1), what is the measure of DF?A-3B-3.1C-5D-5.9Please respond qu
aev [14]

The triangles ABC and EDF are congruent, meaning they have the same side lengths and angles measures.

The measure of DF, as both triangles are congruent, is equal to the measure of BC.

We can calculate the length of BC using the distance formula:

\begin{gathered} D=\sqrt[]{(x_c-x_b)^2+(y_c-y_b_{})^2} \\ D=\sqrt[]{(2-2)^2+(-1-4)^2} \\ D=\sqrt[]{0^2+(-5)^2} \\ D=\sqrt[]{(-5)^2} \\ D=|-5| \\ D=5 \end{gathered}

As BC is congruent with DF and BC=5, the length of DF is 5 units.
