Several million lottery tickets are sold, and 21% of the tickets are held by men. Suppose you select a random sample of people and let X represent the number of people in your sample for which are men with winning tickets. What type of random variable is X?
hypergeometric
Bernoulli
poisson
uniform
Answer:
hypergeometric
Step-by-step explanation:
For each winning ticket, there are only two possible outcomes. Either it is held by a men, or it is not.
There is a set number of X, and as the number of winning tickets decrease, the probability of a winning ticket being held by a men can decrease or increase. This is a characteristic of the hypergeometric distribution.
Solve and graph y−5<7
Answer:
y < 12
Step-by-step explanation:
Add 5 on both sides since the opposite of subtraction is addition. Then cross it out where you will be left with y and 7 + 5 equals 12 so the answer is: y < 12

Six jurors are to be selected from a pool of potential candidates to hear a civil case involving a lawsuit between two families. Unknown to the judge or any of the attorneys, of the prospective jurors are potentially prejudiced by being acquainted with one or more of the litigants. They will not disclose this during the jury selection process. If jurors are selected at random from this group of , find the probability that the number of potentially prejudiced jurors among the selected jurors is exactly .
Complete question :
Six jurors are to be selected from a pool of 20 potential candidates to hear a civil case involving a lawsuit between two families. Unknown to the judge or any of the attorneys, 2 of the 20 prospective jurors are potentially prejudiced by being acquainted with one or more of the litigants. They will not disclose this during the jury selection process. If 6 jurors are selected at random from this group of 20, find the probability that the number of potentially prejudiced jurors among the 6 selected jurors is ;
a. exactly 1
b. none
c. at most 2
Answer:
0.442 ; 0.479 ; 1
Step-by-step explanation:
Given:.
Total number of candidates = 20
Number of jurors to be selected = 6
Number of prejudiced jurors = 2
Required outcome / Total possible outcomes :
Using the combination formula :
nCr = n! ÷ (n-r)!r!
1.)
P(number of prejudiced jurors is exactly 1) :
[2C1 * 18C5] ÷ 20C6
(2*8568)÷ 38760
= 0.442
B.)
P(None of the jurors is prejudiced) :
[2C0 * 18C6] ÷ 20C6
(1 * 18564) ÷ 38760
= 0.479
C.)
P(at most 2 of the jurors are prejudiced)
P(x =0) + p(x = 1) + p(x = 2)
P(x = 2) :
[2C2 * 18C4] ÷ 20C6
(1 * 3060) ÷ 38760
= 0.079
P(x =0) + p(x = 1) + p(x = 2)
(0.479 + 0.442 + 0.079)
= 1
Write an expression that is equivalent to 8(a + 5).
Select the correct answer from each drop-down menu.
(cos2x-cos4x)/(sin2x+sin4x)=
a. cot x
b. tan x
c. sin x
d. cos x
(cos2x+cos4x)/(sin2x-sin4x)=
a. cot x
b. -cot x
c. sin x
d. -tan x
Answer:
[tex](b)\\\tan x, \cot x[/tex]
Step-by-step explanation:
Given
trigonometric function is
[tex]\dfrac{\cos 2x-\cos 4x}{\sin 2x+\sin 4x}[/tex]
Applying trigonometric formulae
[tex]\Rightarrow \cos C-\cos D=-\sin (\dfrac{C+D}{2})\sin (\dfrac{C-D}{2})\\\\\Rightarrow \sin C+\sin D=\sin (\dfrac{C+D}{2})\cos (\dfrac{C-D}{2})[/tex]
[tex]\Rightarrow \dfrac{\cos 2x-\cos 4x}{\sin 2x+\sin 4x}=\dfrac{2\sin 3x\cdot \sin x}{2\sin 3x\cdot \cos x}\\\\\Rightarrow \dfrac{\sin x}{\cos x}=\tan x[/tex]
option (b) is correct
[tex]\Rightarrow \dfrac{\cos 2x+\cos 4x}{\sin 2x-\sin 4x}=\dfrac{2\cos 3x\cdot \cos x}{2\cos 3x\cdot \sin (-x)}=-\cot x[/tex]

WILL GIVE BRAINLIEST!!!!!!! find the value of x. find the value of y.
Answer: x=20 y=20√2
Since this is a 45-90-45 right triangle, so sides are going to be the same. To solve for y, you have to use Pythagorean theorem. (a^2+b^2=c^2) So put in the a and b values, in this case, it's 20 and 20. (20^2+20^2=c^2) Then you can solve the exponents, (400+400=c^2) add them up (800=c^2), then square root everything which gives you y=20√2 or 28.28(rounded)

Apply the distributive property to factor out the greatest common factor. 35+14=35+14=35, plus, 14, equals
Answer:
The greatest common factor is 7
[tex]35 + 14 = 49[/tex]
Step-by-step explanation:
Given
[tex]35 + 14 =[/tex]
Required
Apply distributive property
Express 35 as 7 * 5 and 14 as 7 * 2
[tex]35 + 14 = 7 * 5 + 7 * 2[/tex]
Apply distributive property
[tex]35 + 14 = 7 ( 5 + 2)[/tex]
The greatest common factor is 7
Solving further to get the solution
[tex]35 + 14 = 7 * 7[/tex]
[tex]35 + 14 = 49[/tex]
Answer:
7(5+2)

Answer:
Please answer my question
Answer:
a = 15, b = - 14
Step-by-step explanation:
Given the 2 equations
[tex]\frac{a}{5}[/tex] - [tex]\frac{b}{2}[/tex] = 10 ( multiply through by 10 to clear the fractions )
2a - 5b = 100 → (1)
a - b = 29 → (2)
Multiplying (2) by - 2 and adding to (1) will eliminate the a- term
- 2a + 2b = - 58 → (3)
Add (1) and (3) term by term to eliminate a
0 - 3b = 42
- 3b = 42 ( divide both sides by - 3 )
b = - 14
Substitute b = - 14 into (2) and evaluate for a
a - (- 14) = 29
a + 14 = 29 ( subtract 14 from both sides )
a = 15

Please help mee
Answer:
Options A, D and E
Step-by-step explanation:
If a number in square root can't be solved Or square root of the number can't be removed then it is a surd.
Option A
√17 = Surd [Can't be simplified further]
Option B
√36 = 6
Not a surd
Option C
√100 = 10
Not a surd
Option D
√15 = Surd
Option E
√30 = Surd
Therefore, Options A, D and E are the surd.

I need help finding the rate of change can someone help me
Answer:
rate of change is 4.
Step-by-step explanation:
rate of change is the slope, so, pick any two relations given to us in the table.
(-3, -14) and (-1, -6).
slope = y2 - y1/ x2 - x1
slope = -6 - (-14)/-1-(-3)
slope = 8/2 = 4.
the rate of change is 4.
