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

Answer:
x = 15
yes
Step-by-step explanation:
17²= 289
8²= 64
A² + B² = C²
8²+ B² = 17²
64 + B² = 289
-64 -64
B²= 225

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.

The true equations are given below and this can be determined by using the sum of interior angle properties and the trigonometric functions.
Given :
A triangle ABC is given. Angle A = 48 degrees.The following steps can be used in order to determine the true equations:
Step 1 - First, determine the measure of angle B by using the sum of interior angle property.
[tex]\rm \angle A + \angle B + \angle C = 180^\circ[/tex]
48 + 90 + [tex]\rm \angle B[/tex] = 180
[tex]\rm \angle B[/tex] = 42 degrees
Step 2 - Now, the trigonometric functions can be used in order to determine the true equations.
Step 3 - The expression of the sine function is given below:
[tex]\rm sin42 = \dfrac{b}{c}[/tex]
Step 4 - The expression of the cosine function is given below:
[tex]\rm cos48 = \dfrac{b}{c}[/tex]
Step 5 - The expression of the tangent function is given below:
[tex]\rm tan42 = \dfrac{b}{a}[/tex]
[tex]\rm tan48 = \dfrac{a}{b}[/tex]
Therefore, the true equations are given by options B), C), E), and F).

find the side length
Answer:
area of square=side²
36/49yd²=side²
(36/49yd²)²=side
6/7 yd=side
Answer:
s = [tex]\frac{6}{7}[/tex] yd
Step-by-step explanation:
The area (A) of a square is calculated as
A = s² ( s is the length of side )
Given A = [tex]\frac{36}{49}[/tex] , then
s² = [tex]\frac{36}{49}[/tex] ( take the square root of both sides )
s = [tex]\sqrt{\frac{36}{49} }[/tex] = [tex]\frac{\sqrt{36} }{\sqrt{49} }[/tex] = [tex]\frac{6}{7}[/tex]

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

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)
