Naval intelligence reports that 5 enemy vessels in a fleet of 18 are carrying nuclear weapons. If 9 vessels are randomly targeted and destroyed, what is the probability that no more than 1 vessel transporting nuclear weapons was destroyed
Answers
Answer:
0.1471 = 14.71% probability that no more than 1 vessel transporting nuclear weapons was destroyed.
Step-by-step explanation:
Vessels are chosen without replacement, which means that we use the hypergeometric distribution to solve this question.
Hypergeometric distribution:
The probability of x sucesses is given by the following formula:
[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]
In which:
x is the number of sucesses.
N is the size of the population.
n is the size of the sample.
k is the total number of desired outcomes.
Combinations formula:
[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
Naval intelligence reports that 5 enemy vessels in a fleet of 18 are carrying nuclear weapons.
This means, respectively, that [tex]k = 5, N = 18[/tex].
9 vessels are randomly targeted and destroyed
This means that [tex]n = 9[/tex]
What is the probability that no more than 1 vessel transporting nuclear weapons was destroyed?
This is:
[tex]P(X \leq 1) = P(X = 0) + P(X = 1)[/tex]
In which
[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]
[tex]P(X = 0) = h(0,18,9,5) = \frac{C_{5,0}*C_{13,9}}{C_{18,9}} = 0.0147[/tex]
[tex]P(X = 1) = h(1,18,9,5) = \frac{C_{5,1}*C_{13,8}}{C_{18,9}} = 0.1324[/tex]
[tex]P(X \leq 1) = P(X = 0) + P(X = 1) = 0.0147 + 0.1324 = 0.1471[/tex]
0.1471 = 14.71% probability that no more than 1 vessel transporting nuclear weapons was destroyed.

Is the graph shown at right the graph of -2x + 5y = 20? yes or no? explain your thinking
ILL GIVE YOU BRAINLIST
Answers
Rewrite the equation in slope intercept form.
First add 2x to both sides:
5y = 2x + 20
Divide both sides by 5
y = (2/5)x + 4
Based on this equation, the y-intercept is 4, which is true for the graph. The slope is 2/5, which is also true for the graph, seeing as how there are points at (-5,2), (0,4), and (5,6). Between each point you go 2 up and 5 to the right.

Given system:
2y = 14 - 2x y = -x + 7Divide the first equation by 2 and rearrange:
2y/2 = 14/2 - 2x/2y = 7 - xy = -x + 7We got the same equation with the second one. It means we have two of the same lines overlapping.

Given that the measure of ∠x is 90°, and the measure of ∠y is 64°, find the measure of ∠z.
Answers
Answer:
26°Step-by-step explanation:
Assuming that your figure is a triangle, we should keep in mind that all the interior angles of a triangle add up to 180°, always.
So, we have the values of angles x and y as 90° and 64°.
90 + 64 = 154° ⇒ Add them up.
Now, subtract 154 from 180 to get ∠z.
180 - 154 = 26°

Answer:
30%

64.99 - 45.49 = 19.50
divide the answer by the original price
[tex]\frac{19.50}{64.99}[/tex] = 0.30
multiply the answer by 100
0.30 x 100 = 30%
to check:
take the original number and multiply it by the decimal form of the percentgae:
64.99 x 30% (0.30) = 19.50
take the answer and subtract it from the orginal answer
64.99 - 19.50 = 45.49
Find the measure of angle w
Answers
Answer: Angle w=90
Step-by-step explanation: A line is 180 degress,so 90 plus w = 180. 180-90 is 90, so w is 90.
Answer:
90
Step-by-step explanation:
There is perpendicular bisector separating a given angle of 90, and a variable of w
We can assume the other ray is at a 180 degree angle, this means we can find w by using this simple equation; 180 - (given number) = remaining number, in this case, w.

The length of x in the circle shown will be 5 units.
What is a circle?A circle is a geometric shape that is created by drawing a point in an orbit around a fixed point while maintaining a fixed distance.
The longest line which can be drawn inside the circle will be the diameter.
Area of circle = πr² and the perimeter of circle = 2πr where r is the radius of the circle.
Given the circle with a radius of 5 units.
A radius is a line that goes from the center and touches the periphery of the circle.
Since the x line also goes from the center and touches to the periphery hence, x should be a radius.
Since the radius of a circle is always the same so
x = radius = 5

5x+(2)(6x)+(2)(-2)=98
Then I distributed
5x+12x+-4=98
(5x+12x) + (-4)=98
Then I combined like terms
17x+-4=98
17x-4=98
Then I just added four both sides
17x-4+4=98+4 17x=102
Then lastly I Divided both sides by 17
17x/17 = 102/17 x=6

First we have to find 1 percent of 35, and then we will multiply it by 40. So: 35/100 = 0.35
0.35 (40) = 14
35 - 14 = 21
