The data represent the results for a test for a certain disease. Assume one individual from the group is randomly selected. Find the probability of getting someone who tests ​negative, given that he or she has the disease.
Answer:
[tex]Probability = 0.0470[/tex]
Step-by-step explanation:
This question has missing detail. (See attachment for the data)
Required
Determine the probability that a selected individual who has the disease test negative.
This type of probability is referred to as conditional probability.
First, we need to get the number of individuals who have the disease.
[tex]Disease =142 + 7[/tex]
[tex]Disease =149[/tex]
Next, we list out the number of individual who have the disease but is negative.
[tex]Negative = 7[/tex]
The probability is then calculated as:
[tex]Probability = \frac{Negative}{Disease}[/tex]
[tex]Probability = \frac{7}{149}[/tex]
[tex]Probability = 0.04697986577[/tex]
[tex]Probability = 0.0470[/tex] (approximated)

Step-by-step explanation:
Answer:
x = 3, y = -2.
Step-by-step explanation:
5x + 6y = 3
2x - 3y = 12 Multiply this by 2:
4x - 6y = 24 Now add this to the first equation:
9x = 27
x = 3.
Substitute x = 3 in the second equation:
2(3) - 3y = 12
-3y = 12 - 6 = 6
y = 6 / -3
y = -2.

Answer:
32
Step-by-step explanation:
its just 50 minus 18 and dont forget to borrow
Answer:
32mph
Step-by-step explanation:
So I think all you have to do is subtract 18 from 50 so 50 - 18 = 32mph
So in conclusion the giraffe can run 32mph if a lion is running at 50mph

How long does it take for the contestant to go from A to D if 15 feet is a second. I got 13.333 seconds but it says im wrong. Can someone help me out please
========================================================
Explanation:
Since triangle ABD is congruent to triangle CBD, this means the corresponding pieces AB and BC are the same length. Both are 70 feet.
Similarly, AD = DC = 60 ft.
The total length traveled is:
AB+BC+CD = 70+70+60 = 200 ft
We never use BD = 50 at all.
Divide this total distance over the speed of 15 ft per second, and we get 200/15 = 13.333 seconds approximately.
You are correct so far. You just need to round this value to the nearest tenth, as the instructions indicate. So you'll round to one decimal place. The value 13.333 turns into 13.3 which is the final answer.

How many different triangles ABC can be formed if C=60∘, c=17√3 and a=34?
Answer:
Jordan, Its been 5 hours, whats the answer?
Step-by-step explanation:
There can be only 1 triangle formed by the given information.
What is triangle?A triangle is a closed, 2-dimensional shape with 3 sides, 3 angles, and 3 vertices. A triangle is also a polygon.
Given that, ABC can be formed if C=60∘, c=17√3 and a=34
Using the sine law for triangle,
A/sina = B/sinb = C/sinc
34/sina = 17√3/sin60°
⇒ sina = 90°
Since, The triangle ABC is a right triangle,
Hence, There can be only 1 triangle formed by the given information.

Find the degree measure of the angle with the given radian measure. (Round your answer to one decimal place.)
Answer:
108 degrees
Step-by-step explanation:
Since we are not given the radian measure. Let the radian measure be 3π/5 rad;
Using the conversion;
πrad = 180°
3π/5 rad = x
Cross mulriply;
π * x = 180 * 3π/5
x = 180 * 3/5
x = 36 * 3
x = 108 degrees
Hence the degree measure is 108 degrees
Note that the same conversion can be used to convert other values in radians
