Answers

Answer 1

Answer:

Point B

Step-by-step explanation:

-6 is to the left from origin and π/12 is in between 0 and π/6 above the x-axis. So the point (-6, π/12) is in the second quadrant.

Other points represent coordinates of:

A=(6, π/12), C=(-6, -π/12), D=(6, -π/12)

This is point B and correct choice is option B.

Answer 2

9514 1404 393

Answer:

  point C

Step-by-step explanation:

The given coordinates (-6, π/12) are equivalent to (6, 13π/12). That is, the negative radius is equivalent to a positive radius in the opposite direction (angle different by π radians).

The point on the diagram with coordinates (6, 13π/12) is point C.

X-3y=-12 and 4x+6y=-12 substitution

Answers

Answer:

x = -6

y = 2

Step-by-step explanation:

1. Approach

x - 3y = -12

4x + 6y = -12

In this problem, it would likely be easier to use elimination, but since the problem specifically says that one must use substitution, substitution will be used. Substitution is when one solves one of the equations for a variable, similar to solving a literal equation. The one will substitute in the value of the variable into the other equation and solve for the other varibale. Then one will finally back substitute in that value of the other variable to find the value of the first variable, hence solving the equation.

2. Solve equation 1

x - 3y = -12

Solve the literal equation with inverse operations;

x - 3y = -12

   +3y    + 3y

x = 3y - 12

3. Substitute the answer into the second equation

4x + 6y = -12

x = 3y - 12

4 ( 3y - 12 ) + 6y = -12

Distribute;

12y - 48 + 6y = -12

Simplify;

12y - 48 + 6y = -12

18y - 48 = -12

Inverse operations;

18y - 48 = -12

     +48     +48

18y = 36

/18   /18

y = 2

4. Backsolve for x

Substitute the value for y back into the equation for x and solve

x = 3y - 12

y = 2

x = 3(2) - 12

x = 6 - 12

x = -6

At a certain company, loan agents are paid based on the number of loans they close in a day. Based on company records, the number of loans X that a randomly selected loan agent closes on a randomly selected day has the probability distribution below.x 1 2 3 4 5 6 7p(x) 0.05 0.10 0.22 0.30 0.18 0.12 0.03 At the company, the daily salary of a loan agent is $150 plus $50 per loan closed. Let YY represent the amount of money made by a randomly selected loan agent on a randomly selected day. Which of the following statements is NOT true?A. The mean of X is less than the mean of Y. B. The standard deviation of Y is approximately $71. C. The mean daily salary is greater than $350 per day. D. The standard deviation of X is less than the standard deviation of Y. E. The shape of the probability distribution of Y is unimodal and roughly symmetric.

Answers

Answer:

C. The mean daily salary is greater than $350 per day

Step-by-step explanation:

The computation is shown below:

Y = a + bX

where,

Y = money made by a random selected

a = $150

b = $50

X = number of loan

Now

E(x) = (1 × 0.05) + (2 × 0.10) + (3 × 0.22) + (4 × 0.30) + (5 × 0.18) + (6 × 0.12) + (7 × 0.03)

= 3.94

Now

E(y) = $150 + ($50 × 3.94)

= $347

hence, the option C is not correct

The mean daily salary is greater than $350 per day and this can be determined by using the given data.

Given :

At a certain company, loan agents are paid based on the number of loans they close in a day.

The computation is given by:

Y = a + bX

where Y is the money made by randomly selected, a is $150, b is $50, and X is the number of loans.

Now, the value of E(x) is given by:

[tex]\rm E(x) = (1\times 0.5)+(2\times 0.1)+(3\times 0.22)+(4\times 0.3)+(5\times 0.18)+(6\times 0.12)+(7\times 0.03)[/tex]

[tex]\rm E(x) = 3.94[/tex]

Now, the value of E(y) is given by:

[tex]\rm E(y) = 150+(50\times 3394)[/tex]

E(y) = $347

So, the correct option is given by C) The mean daily salary is greater than $350 per day.

A survey of 280 homeless persons showed that 63 were veterans. Construct a 90% confidence interval for the proportion of homeless persons who are veterans.

Answers

Answer:

[0.184, 0.266]

Step-by-step explanation:

Given:

Number of survey n =280

Number of veterans = 63

Confidence interval = 90%

Computation:

Probability of veterans = 63/280

Probability of veterans =0.225

a=0.1

Z(0.05) = 1.645 (from distribution table)

Confidence interval = 90%

So,

p ± Z*√[p(1-p)/n]

0.225 ± 1.645√(0.225(1-0.225)/280)

[0.184, 0.266]

Answer:

[tex]\large\boxed{\boxed{\pink{\bf \leadsto (-2,2) \ is \ the \ solution \ of \ the \ given \ linear \ equations .}}}[/tex]

Step-by-step explanation:

Given to equations to us are ,

[tex]\qquad \red{\bullet} \: y = x + 4 \\\\\qquad \red{\bullet} \: y = -2x - 2 [/tex]

And we need to find the solution using graphical method.

So , after plotting the graph of both equations the point where both lines intersect will be the solution of the graph.

And , for plotting we need at least two points .

For equation (1) :-

[tex]\implies y = x + 4 [/tex]

When x = (-4) .

[tex]\implies y = -4+4\\\\\bf\implies y = 0 [/tex]

When x = (-3)

[tex]\implies y = -3+4\\\\\bf\implies y = -1 [/tex]

[tex]\large\boxed{\begin{tabular}{|c|c|c|} \cline{1-3} \bf x & (-4) & (-3) \\\cline{1-3} \bf y & 0 & 1 \\\cline{1-3}\end{tabular}}[/tex]

For equation 2 :-

[tex]\implies y = -2x - 2 [/tex]

When x = (-1) .

[tex]\implies y = -2(-1)-2\\\\\bf\implies y = 0 [/tex]

When x = (0)

[tex]\implies y = 0-2\\\\\bf\implies y = -2 [/tex]

[tex]\large\boxed{\begin{tabular}{|c|c|c|} \cline{1-3} \bf x & (-1) & 0 \\\cline{1-3} \bf y & 0 & -2 \\\cline{1-3}\end{tabular}}[/tex]

Now , let's plot their graphs. Graph is in attachment. Hence on plotting the graph we see that both the lines Intersect on (-2,2) . Hence x = -2 and y = 2 is the solution of the given linear equation.

Hence (-2,2) is the solution of the given pair of linear equations in two variables.

Answer:

B.  BD = 67

Step-by-step explanation:

ABCD is a square.

BD and AC are diagonals and they have equal length.

We have AC = 7x + 18 and BD = 10x - 3

Since AC = BD, we substitute their values and solve for x:

7x + 18 = 10x - 310x - 7x = 18 + 33x = 21x = 21/3x = 7

Then find the length of BD:

BD = 7x + 18 = 7*7 + 18 = 49 + 18 = 67

Correct option is B.  BD = 67

Jason buys 8 colored markers at the art store. He handed the cashier $15. The cashier gave him back $1. How much did each marker cost?

Answers

Answer:

2.25

Step-by-step explanation:

i think though

Each colored marker costs $1.75.

What is Unit Rate?

The amount of one quantity in another single quantity is termed as the unit rate of that quantity.

For example, speed is a unit rate in terms of distance and speed.

Number of colored markers Jason bought = 8

Cash that Jason gives the cashier = $15

Cash that cashier gives back = $1

Price of 8 colored markers = 15 - 1

                                             = $14

We have to find the unit rate of the colored marker, that is the price of one colored marker.

Let x be the cost of the one colored marker.

Using proportion,

8 : 14 = 1 : x

8/14 = 1/x

Doing cross multiplication,

8x = 14

x = 14/8

x = 1.75

Hence the unit rate of the colored marker or the cost of one colored marker is $1.75.
