Answer:

Step-by-step explanation:

Price of 1 DVD: $9.10

Price of 4 DVDs: 4 * $9.10 = $36.40

Discount: 25%

Now we find 25% of $36.40.

25% of $36.40 =

= 0.25 * $36.40

= $9.10

The 25% discount amounts to $9.10. We now subtract $9.10 from $36.40 to find the discounted price.

$36.40 - $9.10 = $27.30

Now we need to apply the 6.75% tax to $27.30.

6.75% of $27.30 =

= 0.0675 * $27.30

= $1.84

The sales tax is $1.84.

Now we add the sales tax amount to the total discounted price.

$27.30 + $1.84 = $29.14

Answer: $27.14

Answer:

  no solution

Step-by-step explanation:

The equations are inconsistent. The set of equations reduces to ...

  x + 2y + 3z = 12

  x + 2y + 3z = 30

  x + 2y + 3z = 60

No values of x, y, and z can satisfy all three equations. There is no solution.

Answer:

6/7

Step-by-step explanation:

First you just have to plug the numbers in so you get 3*-4/-2+(-12) which simplifies to -12/-14 which can be simplified to 6/7

The value of expression bd/a+c will be 6/7.

What is substitution method?

To find the value of any one of the variables from one equation in terms of the other variable is called the substitution method.

Given that;

The expression is ,

bd / a+c

And, The values are a=−2 , b=3 , c=−12 , and d=−4.

Now, Find the value of the expression we can substitute all the given values in the expression;

⇒ bd / a+c

⇒ 3 × (-4) / -2+(-12)

⇒ -12/-2-12

⇒ -12/-14

⇒ 12/14

⇒ 6/7

Thus, The value of expression bd/a+c will be 6/7.

No

Step-by-step explanation:

SD=8+2+5+4+11+9÷6

13=10+9+20÷6

13=19+20÷6

13=39÷6

13=6.5-False=No

13 is not a usual number. A further solution of the given query is provided below.

Given:

Number of observations = 6

Series 8, 2, 5, 4, 11, 9

The Mean will be:

= [tex]\frac{Sum \ of \ observation}{Total \ number \ of \ observations}[/tex]

By substituting the values, we get

= [tex]\frac{8+2+5+4+11+9}{6}[/tex]

= [tex]\frac{32}{6}[/tex]

= [tex]6.5[/tex]

Now,

The Standard deviation will be:

The probability of drawing a red chip from bowl B will be ( 23 / 40 ).

Probability is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.

Probability = Number of favourable outcomes / Number of sample

Bowl A contains three red and two white chips, and bowl B contains four red and three white chips. A chip is drawn at random from bowl A and transferred to bowl B.

The probability will be calculated as:-

[tex]\rm P_B(r)=P_A(r)P_B(r)+P_A(w)P_B(r)\\\\P_B(r) = (\dfrac{3}{5})(\dfrac{5}{8})+(\dfrac{2}{5}(\dfrac{4}{8})\\\\P_B(r)=\dfrac{23}{40}[/tex]

B) -6 is the answer :) :) *-*

Multiply both sides by 2pi:

F(2pi) = sqrt(g/l)

Square both sides:

F^2 (2pi)^2 = g/l

Solve for l by dividing both sides by F^2 (2pi)^2

L = g/ F^2 (2pi)^2

Simplify:

L = g / 4pi^2(f^2)

A function is given to us and we need to find its range. So the given function is ,

The upper bound of the range for sine is found by substituting the positive magnitude of the coefficient into the equation.

Answer:

Step-by-step explanation:

Answer:

A.)

0.852 ; 0.999 ; 0.013

B.)

0.018 ; 0.593 ; 0.050

Step-by-step explanation:

Given :

Proportion of marketing personnel that are extrovert, p = 0.75

1 - p = 1 - 0.75 = 0.25

Proportion of computer programmers that are introverts, p = 0.55

1 - p = 1 - 0.55 = 0.45

According to binomial distribution formula :

P(x =x) = nCx * p^x * (1 - p)^(n - r)

A.) n = 15

Probability that 10 or more are extrovert

P(x ≥ 10) = p(x = 10) + p(x = 11) +... p(x = 15)

To save computation time, we can use a binomial probability calculator ;

P(x ≥ 10) = 0.8516 = 0.852

Probability that 5 or more are extrovert :

P(x ≥ 5) = p(x = 5) + p(x = 6) +... p(x = 15)

To save computation time, we can use a binomial probability calculator ;

P(x ≥ 5) = 0.9999 = 0.999

Probability that all are extrovert :

P(x = 15) = 15C15 * 0.75^15 * 0.25^0

P(x = 15) = 1 * 0.75^15 * 0.25^0

P(x = 15) = 0.01336 = 0.013

B.

What is the probability that all are introverts?

n = 5

None are introvert :

P(x = 0) = 5C0 * 0.55^0 * 0.45^5

P(x = 0) = 1 * 1 * 0.0184528125

P(x = 0) = 0.01845 = 0.018

P(x ≥ 3) = p(3) + p(4) + p(5)

To save computation time, we can use a binomial probability calculator ;

P(x ≥ 3) = 0.5931 = 0.593

Probability that all are introvert

P(x = 5) = 5C5 * 0.55^5 * 0.45^0

P(x = 5) = 1 * 0.55^5 * 0.45^0

P(x = 5) = 0.0503 = 0.050

S0, [tex]t=2.713 hr[/tex]

Answer:

( -2, 3 )

Step-by-step explanation:

3x + y = -3

y = x + 5

Since "y" has been given to us, all we need to do is substitute.

3x + x + 5 = -3

Combine like terms

4x + 5 = -3

Subtract 5 onto both sides

4x + 5 - 5 = -3 - 5

4x = -8

Divide by 4 into both sides to isolate the variable

4x/4 = -8/4

x = -2

Now that we have x ( -2 ), we can substitute that to get what y is.

y = x + 5

y = -2 + 5

y = 3

( x, y ) ---> ( -2, 3 )
