A complex number, (a + bi), multiplied by (2 + 3i) and added to -i gives the product of (-11 + 5i) and (1 – i).a = and b =

Answers

Answer:

Hence, we have:

               a= 3 and b= 4

Step-by-step explanation:

It is given that:

A complex number, (a + bi), multiplied by (2 + 3i) and added to -i gives the product of (-11 + 5i) and (1 – i).

i.e.

(a+ib)(2+3i)-i=(-11+5i)(1-i)\n\ni.e.\n\na(2+3i)+ib(2+3i)-i=-11(1-i)+5i(1-i)\n\ni.e.\n\n2a+3ai+2bi+3bi^2-i=-11+11i+5i-5i^2

Since, we know that :

i^2=-1

Hence, we have:

2a+3ai+2bi-3b-i=-11+11i+5i+5\n\ni.e.\n\n(2a-3b)+i(3a+2b-1)=-11+5+11i+5i\n\ni.e.\n\n(2a-3b)+i(3a+2b-1)=-6+16i

i.e. we have:

2a-3b=-6---------(1)

and

3a+2b-1=16\n\ni.e.\n\n3a+2b=16+1\n\ni.e.\n\n3a+2b=17------------(2)

On multiplying equation (1) by 2 and equation (2) by 3 we get:

13a=39\n\ni.e.\n\na=3

on putting the value of a into equation (1) we get:

2* 3-3b=-6\n\ni.e.\n\n6-3b=-6\n\ni.e.\n\n-3b=-6-6\n\ni.e.\n\n-3b=-12\n\ni.e.\n\nb=4
(a+bi)(2+3i)-i=(-11+5i)(1-i)
2a+3ai+2bi+3bi²-i=-11+11i+5i-5i²
2a+(3a+2b-1)i-3b=-11+16i+5
(2a-3b)+(3a+2b-1)i=-6+16i
Therefore; we have the next system of equations:
2a-3b=-6
3a+2b-1=16

Finally, the system of equations is:
2a-3b=-6
3a+2b=17
We can solve this system of equations by reduction method
 2(2a-3b=-6) 
 3(3a+2b=17)
----------------------
   13a=39  ⇒a=39/13=3

 3(2a-3b=-6)
-2(3a+2b=17)
----------------------
       -13b=-52   ⇒ b=52/13=4

Answer: a=3;    b=4

A football coach gives half his players a protein bar to eat before each game; the other players do not receive the protein bar. After a month of games, he analyzes their playing stats. He concludes the protein bar helped improve their performance on the field. How can the coach test the means to be sure the results are not likely to happen by chance?A.He can rerandomize the results by separating the two groups randomly, then calculate the means and the difference of the means.
B.He can pick players at random and analyze their playing stats without calculating means.
C.He can analyze the two groups by calculating the means and the difference of the means.
D.He can pick the players he wants to analyze based on the best stats.

Answers

Answer:

The answer is option A.

Step-by-step explanation:

How can the coach test the means to be sure the results are not likely to happen by chance?

A.He can re randomize the results by separating the two groups randomly, then calculate the means and the difference of the means. (This is because, in statistical data, it cannot happen by chance. It has to be a valid occurrence, nothing by chance.)

Answer:

A.He can rerandomize the results by separating the two groups randomly, then calculate the means and the difference of the means.

Step-by-step explanation:

He can randomize again the players that are receiving the bar and those who are not, and then after that he can see if the results from the previous experiment were accurate or if they happened just by chance. In this way he can make sure that if the results with this two new groups after randomizing are the same that the bar is actually improving the players an edge on performance.

Answer:

B. $13.75.

Step-by-step explanation:

To find the bill for lunch before the tip was added, we can set up an equation using the given information.

Let's assume the bill for lunch is represented by the variable "x".

We know that Mrs. Chin paid a 20% tip on the bill, which is equivalent to 0.20x.

According to the question, the tip amount is $2.75.

So we can write the equation as:

0.20x = $2.75

To solve for x, we need to isolate it.

Divide both sides of the equation by 0.20:

x = $2.75 / 0.20

Simplifying this gives us:

x = $13.75

Therefore, the bill for lunch before the tip was added is $13.75.

Jack mows the lawn in 3 hours. Jane mows the same yard in 4 hours. If they worked together how much time would it take them to mow the yard?

Answers

Jack mows 1/3 of the lawn each hour.
Jane mows 1/4 of the lawn each hour.

Working together, they mow (1/3 + 1/4) of the lawn each hour.

In order to add the fractions, you need a common denominator.
12 will work:

(1/3 lawn/hour + 1/4 lawn/hour) = (4/12 + 3/12) = 7/12 lawn/hour.

This rate of work produces 12/7 hour/lawn.

12/7 hour = 1 hour    42 minutes    51.4 seconds
(1)/(3)+(1)/(4)=(1)/(x)\n (4)/(12)+(3)/(12)=(1)/(x)\n (7)/(12)=(1)/(x)\n 7x=12\n x=(12)/(7)\hbox { h}=1\hbox{ h }42\hbox{ min } 51.43 \hbox{ s}

Read the complete problem before answering. Tang bought m of rope. Rope costs $1.30 a meter. How much did Tang spend? A student solved the problem this way. m = 1.5 m Let n represent the amount Tang paid for rope. n = 1.5 × $1.30 n = $1.95 Tang spent $1.95. Use a similar strategy to solve this problem. Jeff bought yards of blue denim and yards of black denim. Denim cost $4.30 a yard. How much did Jeff spend on denim? A. $3.50 B. $7.80 C. $12.90 D. $15.05

Answers

You would do 4.30*(how many yards) which would equal the total price.  But I cannot solve it for you seeing as the question lacks the necessary information.
