let d be the difference in the number of puzzles solved by two randomly selected subjects in a 5-minute period. what is the standard deviation of d?

Answers

Answer 1

A randomly selected subject has a 0.40 probability of completing more tasks than expected in 5 minutes while listening to relaxing music.

The Probability distribution is:

    X                     1                    2                3              4          

   P(x)             0.20          0.40      0.30             0.10

If listening to soothing music, the expected number of puzzles in 5 minutes can be calculated as follows:

            E(x) = ∑x p(x)

       ⇒ E(x) = 1 ×(0.20) + 2× 0.40 + 3 × 0.30 + 4× 0.1

       ⇒ E(x) = 0.20 + 0.8 + 0.9 + 0.4

       ⇒ E(x) = 2.3

Thus, a randomly selected subject could solve 5 puzzles while listening to soothing music. The probability of solving more tasks than expected in a minute is calculated as:

    P( X > 2.3) = P(X = 3) + P(X = 4)

                      = 0.30 + 0.10

                      = 0.40

Explanation for other  option:

(a) The probability that a randomly selected participant completes more tasks than expected in 5 minutes while listening to relaxing music does not equal 0.1.

(c) 5 randomly selected participants. The probability of completing more tasks than expected in a minute of listening to relaxation music does not equal 0.8.

(d) The probability that a randomly selected participant completes more tasks than expected in 5 minutes while listening to relaxing music is not equal to 1.

(e) The likelihood of randomly selected participants completing more tasks than expected in 5 minutes while listening to relaxing music cannot be determined.

y+4=3(x-3) rewrite in Ax+By=C

Answers

Answer:

0=3x-y=-13

Step-by-step explanation:

Answer:

In the equation y+4=3(x-3), we can see that x and y are the variables and 4 and -3 are the constants.

To convert the equation to the form Ax + By = C, we'll first distribute the 3 on the right side:

y + 4 = 3x - 9

Next, we'll move all the terms with x to one side of the equation and all the terms with y to the other side:

-3x + y =  - 13

Now we have the equation in the form Ax + By = C, where A = -3, B = 1, and C = -13.

a small computing center has found that the number of jobs submitted per day to its computers has a distribution that is approximately mound-shaped and symmetric, with a mean of 84 jobs and a standard deviation of 9. where do we expect approximately 95% of the distribution to fall?

Answers

Our confidence interval is (66, 102).

In statistics, a confidence interval describes the likelihood that a population parameter would fall between a set of values for a given percentage of the time. Confidence ranges that include 95% or 99% of anticipated observations are frequently used by analysts. Therefore, it can be concluded that there is a 95% probability that the true value falls within that range if a point estimate of 10.00 is produced using a statistical model with a 95% confidence interval of 9.50 - 10.50.

Now, here:

Mean, μ = 84

Standard deviation, σ = 9

It is a 95% confidence interval. We know that, within 2 standard deviations of the mean lies 95% of the population. Hence, z = 2.

Now, calculating μ - z.σ and μ + z.σ to find the intervals.

μ - z.σ  = 84 - 2x9 = 66

μ + z.σ = 84 + 2x9 = 102

Thus, our confidence interval is (66, 102).

On a coordinate plane, a parabola opens down. It goes through (negative 2, negative 2), has a vertex at (1.5, 10), and goes through (5, negative 2).
Over which interval is the graph of f(x) = –x2 + 3x + 8 increasing?

Answers

This simplifies to x<3/2. So the graph of f(x) = –x^2 + 3x + 8 is increasing over the interval (-infinity,3/2)

What is the interval?

Generally, The vertex form of a parabola that opens downward is

f(x) = a(x-h)^2 + k,

where (h,k) is the vertex of the parabola.

We know that the vertex of the parabola is at (1.5, 10) so we can use that to find the value of a and h. So,

f(x) = a(x-1.5)^2 + 10

Given that the parabola goes through (- 2, - 2) and (5, - 2), we can substitute these points into the equation to find a and k.

Substituting (-2, -2) into the equation:

-2 = a((-2) - 1.5)^2 + 10

Substituting (5, - 2) into the equation:

-2 = a(5 - 1.5)^2 + 10

Solving these two equations will give you a = -1/2 and k = -8

So the equation is f(x) = -1/2(x-1.5)^2 - 8

The graph of a parabola is increasing on the interval where the derivative is greater than 0.

To find the derivative, we use the power rule and the chain rule:

f'(x) = -1/2(2x-3)

= -x+3/2

So, the graph of f(x) is increasing when -x+3/2 > 0

Answer:

y = -0.5x + 5.5

Step-by-step explanation:

A linear function can be represented in the form of y = mx + b, where m is the slope and b is the y-intercept. The slope of a line is the ratio of the change in y to the change in x (rise over run) and the y-intercept is the point where the line crosses the y-axis.

To find the rule for this linear function, we can use the two points (x1, y1) and (x2, y2) to find the slope m:

m = (y2 - y1) / (x2 - x1)

If we use the points (7, 2) and (5, 3) to find the slope, we have:

m = (3 - 2) / (5 - 7) = 1 / (-2) = -0.5

We can also use the point (x1, y1) to find the y-intercept b:

b = y1 - m * x1

If we use the point (7, 2) to find the y-intercept, we have:

b = 2 - (-0.5) * 7 = 2 + 3.5 = 5.5

So the rule for the linear function is:

y = -0.5x + 5.5

We can confirm this rule by checking the point (x=-1,y=6)

y = -0.5(-1) + 5.5 = 6

We are given that;

A regular octagon has equal sides = 9 feet and an apothem of 10.9 feet

The cost of the railing if it sells = $7.90 per foot

Now,

Let’s assume that the person has bought x pens.

The total cost of the pens would be 9x dollars.

The shopkeeper has given a discount of 70 dollars. So the total cost of the pens after discount would be 9x - 70 dollars.

We need to find the maximum number of pens he can buy now.

Find the value of (x − 6)² if x² – 12x = 30, and x > 0.

plsss answer ​

Answers

Answer:

65.9

Step-by-step explanation:

The equation x² – 12x = 30 (x>0) promises that we can determine possible values of x if we solve the equation.  So let's start there:

We can factor the equation or solve it with the quadratic equation.

Factor

  x² – 12x = 30

  x² – 12x - 30 = 0

I don't see an easy factor solution.  One possibility is to first rewrite the equation as

  (x-12)x-30 = 0

  (x-6)^2 - 66 = 0

 -(-x+[tex]\sqrt66}[/tex]+6)(x+[tex]\sqrt{66}[/tex]-6)

The roots are:

x = 6-[tex]\sqrt{66}[/tex] and

x = 6+[tex]\sqrt{66}[/tex]

Since x>0, only the second root is valid:  x = 6+[tex]\sqrt{66}[/tex]

x = 6 + (8.12)

x = 14.12

[That was painful]

Quadratic Equation

Solving with the quadratic equation gives values of:

14.12, and -2.12  Again, only the positive value is valid:  14.12

[The quadratic approach was far easier than factoring, in this case]

==

Since we established x = 14.12, (x − 6)² bcomes:

  (14.12 − 6)²

 (8.12)² = 65.9

Answer:

x = -2, x = -4

Step-by-step explanation:

Given quadratic equation:

[tex]x^2+6x+8=0[/tex]

Solve by the method of Completing the Square.

Step 1

When completing the square for a quadratic equation in the form ax²+bx+c=0, the first step is to move the constant to the right side of the equation:

[tex]\implies x^2+6x=-8[/tex]

Step 2

Add the square of half the coefficient of the term in x to both sides to form a perfect square trinomial on the left side:

[tex]\implies x^2+6x+\left(\dfrac{6}{2}\right)^2=-8+\left(\dfrac{6}{2}\right)^2[/tex]

Simplify:

[tex]\implies x^2+6x+3^2=-8+3^2[/tex]

[tex]\implies x^2+6x+9=-8+9[/tex]

[tex]\implies x^2+6x+9=1[/tex]

Step 3

Factor the perfect square trinomial on the left side:

[tex]\implies (x+3)^2=1[/tex]

Step 4

Square root both sides:

[tex]\implies \sqrt{(x+3)^2}=\sqrt{1}[/tex]

[tex]\implies x+3=\pm1[/tex]

Step 5

Subtract 3 from both sides:

[tex]\implies x+3-3=\pm1-3[/tex]

[tex]\implies x=-4, -2[/tex]

Therefore, the solutions of the given quadratic equation are:

What is a class 12 vector?

There are different quantities, which include direction and magnitude. If the quantity has both magnitude and direction, it is said to be a vector. These are referred to as vector quantities. Examples include displacement, speed, acceleration, energy, weight, impetus, and electric intensity. Consequently, the vector quantity is and the SI unit for it is m/s².

The given line is-

x = -1+4t, y = 6-2t, z = 3+9t

That is,

r(t) = <-1+4t, 6-2t, 3+9t> = < -1,6,3> +t<4, -2,9>

The line concurrent to the given line's direction vector is

u = <4,-2,9>

Equation for line going through point (x0,y0,z0) and has direction vector u is line passing through point (0,15,-9)

r(t) = < x0, y0,z0> +tu

That is

r(t) = <0,15, -9> +t<4,-2,9>

The solution to the system in given tables of line 1 and line 2, using linear equation is (b) (0,5)

What is linear equation?

A linear equation is one that has a degree of 1 as its maximum value. No variable in a linear equation, thus, has an exponent greater than 1. A linear equation's graph will always be a straight line.

from the table of line 1, the equation of line is

y = 2x +5.

from the table of line 2, the equation of line is

y = 5 - x

to find the solution of the system, we compare both of the equation, we get

2x + 5 = 5 - x

add x from both side, we get

3x + 5 = 5

subtract 5 from both side, we get

3x = 0

So that, x = 0

putting the value of x in the equation of line 2

y = 5 - x

y = 5 - 0

y = 5

The solution to the system in given tables of line 1 and line 2 is (0,5)

Annual Salary: $24,872; personal exemptions: $1,500.
This person is paid semimonthly.
Use the following graduated income tax rates and find the income tax withheld per pay
period.
First $10,000 is 2.75%
Next $15,000 is 3.25%

Answers

If Annual Salary: $24,872; personal exemptions: $1,500.  the income tax withheld per pay is: $29.57 per pay period.

How to find the income tax withheld per day?

Total taxable income = $24,872 - $1,500

Total taxable income = $23,372

The first $10,000 is taxed at a rate of 2.75%.  The tax owed on the first $10,000 is:

$10,000 * 0.0275

= $275.

The remaining $13,372 ($23,372 - $10,000) is taxed at a rate of 3.25%, so the tax owed on this amount is:

$13,372 * 0.0325

= $434.57

The total tax owed is:

$275 + $434.57

= $709.57

Since the person is paid semimonthly, we divide the annual tax owed by 24 to find the tax withheld per pay period:

$709.57 / 24

= $29.57 per pay period

Therefore the income tax withheld per pay is: $29.57 per pay period.

What is the range of slope?

Answers

Range of slope is from 0 to 90 degrees.

X is the midpoint of UV, Y is the midpoint of UW, and T is the midpoint of VW. If mZU= 56° and mZV=41°, find mZTYW.

Answers

Answer: We know that T is the midpoint of VW, which means that ZW = ZV. So we can say that ZV = ZW = 41°.

Also, we know that Y is the midpoint of UW, so the angle ZYU is half of ZUW. So we can say that ZYU = ZUW/2.

We know that X is the midpoint of UV, so the angle ZXU is half of ZUV. So we can say that ZXU = ZUV/2.

Since Y is the midpoint of UW, ZYU + ZXU = ZUW/2 + ZUV/2 = ZUW/2 + (ZUW - ZXU)/2 = ZUW/2 + (ZUW - ZUV/2)/2 = ZUW/2 + (ZUW - ZUW/2)/2 = ZUW/2 + ZUW/4 = (3/4)ZUW

We know that X is the midpoint of UV, so ZXU + ZVU = ZUV/2 + ZUV = ZUV

The angle ZTYW is supplementary to the angle ZXU + ZVU + ZYU so mZTYW = 180 - ( ZXU + ZVU + ZYU)

Therefore, mZTYW = 180 - ( ZUV + (3/4)ZUW + 41)

mZTYW = 180 - (56 + (3/4)56 + 41) = 180 - (56 + 42 + 41) = 180 - 139 = 41 degrees
