A warehouse employs 21 workers on first shift, 15 workers on second shift, and 13 workers on third shift. Eight workers are ch

Crank

Answer: Our required probability is 0.11.

Step-by-step explanation:

Since we have given that

Number of workers in first shift = 21

Number of workers in second shift = 15

Number of workers in third shift = 13

We need to find the probability of choosing exactly two second shift workers and two third shift workers.

So, it becomes,

$\dfrac{^{15}C_2\times ^{13}C_2\times ^{21}C_4}{^{49}C_8}\\\\=0.11$

Hence, our required probability is 0.11.

WILL GIVE BRAINLIEST! Show that diagonals of MNPQ are congruent if M (3, 2), N(3, –1), P(7, –1), and Q(7, 2). Provide your compl

Tcecarenko [31]

Answer:

Yes the Diagonals are congruent

Step-by-step explanation:

Show that diagonals of MNPQ are congruent if M (3, 2), N(3, –1), P(7, –1), and Q(7, 2)

We are given the coordinates if a quadrilateral.

The first step would be to find the length of the sides of the quadrilateral, using the formula

√(x2 - x1)² + (y2 - y1)²

When given coordinates (x1, y1) , (x2, y2)

M (3, 2), N(3, –1), P(7, –1), and Q(7, 2)

For MN

M (3, 2), N(3, –1),

=√(3 - 3)² + (-1 -2)²

= √0² + -3²

= √9

= 3

For NP

N(3, –1), P(7, –1)

=√(7 - 3)² +(-1 - (-1))²

= √4² + 0²

= √16

= 4

For PQ

P(7, –1), and Q(7, 2)

=√(7 - 7)² +(2 - (-1))²

= √0² + 3²

= √9

= 3

For MQ

M (3, 2),Q(7, 2)

= √(7 - 3)² + (2 - 2)²

= √4² + 0²

= √16

= 4

From the above solution,

We can see that

Side NP = Side MQ

Side PQ = Side MN

Hence this Quadrilateral is as Rectangle

Side PQ = Side MN = Width = 3

Side NP = Side MQ = Length = 4

To find out if their diagonals are congruent we make use of Pythagoras Theorem

Diagonal is the line that divides a quadrilateral into 2 halves

Width 3, Length = 4

= W² +L² = Diagonal ²

= 3² + 4² = D²

= 9 + 16 = D²

= √25 = D

D = 5

Since the Width and Length are the same for the other side, the diagonal would also be equal to 5

Therefore, their diagonals are congruent i.e they are the same

Solve for x:<br> 3x – 2(6 - x) = 7x + 2(5 + x) – 6

MAVERICK [17]

Answer:

-4

Step-by-step explanation:

3x-2(6-x)=7x+2(5+x)-6

First, distribute.

3x+ −12+ 2x = 7x + 10 + 2x −6

Combine like terms on each side.

5x − 12= 9x + 4

To solve for x, pick a side to solve. I will solve the right x.

5x - 12 = 9x + 4

-5x -5x

-12 = 4x + 4

Subtract 4 to isolate the variable.

-16 = 4x

Divide 4.

-4 = x
