Answer:

The margin of error for the 94% confidence interval is 0.6154.

Step-by-step explanation:

The (1 - α)% confidence interval for population mean is:

[tex]CI=\bar x\pm z_{\alpha/2}\cdot\frac{\sigma}{\sqrt{n}}[/tex]

The margin of error of this interval is:

[tex]MOE=z_{\alpha/2}\cdot\frac{\sigma}{\sqrt{n}}[/tex]

The critical value of z for 94% confidence level is, z = 1.88.

Compute the margin of error for the 94% confidence interval as follows:

[tex]MOE=z_{\alpha/2}\cdot\frac{\sigma}{\sqrt{n}}[/tex]

          [tex]=1.88\times\frac{3}{\sqrt{84}}\\\\=0.6154[/tex]

Thus, the margin of error for the 94% confidence interval is 0.6154.

Answer:

B on edge 2022

Explanation:

Picture:

The time it takes the rock to reach the canyon floor is 8.5 seconds.

Option C is the correct answer.

An equation contains one or more terms with variables connected by an equal sign.

Example:

2x + 4y = 9 is an equation.

2x = 8 is an equation.

We have,

Using the quadratic formula.

t = (-b ± √(b² - 4ac)) / 2a

where a = -16, b = 0, and c = 255.

Now,

Plugging in the values.

t = (-0 ± √(0² - 4(-16)(255))) / 2(-16)

t = (± √(16320)) / (-32)

t = (± 128) / (-32)

So,

The solutions for t.

t = 4 seconds (taking the negative solution)

t = 8.5 seconds (taking the positive solution)

We can eliminate t = 0.87 seconds and t = 16 seconds as they are not solutions to the equation.

Therefore,

The time it takes the rock to reach the canyon floor is 8.5 seconds.

Answer:

Option c: 61° is the correct answer

Step-by-step explanation:

By the diagram attached with the question, we can conclude that a transversal is interesting two parallel lines which results in formation of 8 angles.

Angle 3 and angle 5 are interior angles on same side of transversal.

When a transversal intersects two parallel lines, the interior angles on same side of transversal are supplementary angles i.e. their sum is 180°

So using this

m∠3+m∠5 = 180°

m∠3 + 119° = 180°

m∠3 = 180°-119°

m∠3 = 61°

Hence,

Option c: 61° is the correct answer

Answer:

[tex]\dfrac{0.7\pi}{5.3}\cos(\dfrac{2\pi t}{5.3})[/tex]

0.16

Step-by-step explanation:

According to the question the mathematical model should be

[tex]B(t)=2.9+0.35\sin(\dfrac{2\pi t}{5.3})[/tex]

Differentiating with respect to time we get

[tex]B'(t)=0.35\cos(\dfrac{2\pi t}{5.3})\times(\dfrac{2\pi}{5.3})\\\Rightarrow B'(t)=\dfrac{0.7\pi}{5.3}\cos(\dfrac{2\pi t}{5.3})[/tex]

So, the rate of change of brightness after t days is [tex]\dfrac{0.7\pi}{5.3}\cos(\dfrac{2\pi t}{5.3})[/tex]

After 1 day means [tex]t=1[/tex]

[tex]B'(1)=\dfrac{0.7\pi}{5.3}\cos(\dfrac{2\pi\times 1}{5.3})\\\Rightarrow B'(1)=0.16[/tex]

The rate of increase after one day is 0.16.

Answer:

probability that student passes = 0.7815

Step-by-step explanation:

Given:

Student studies = 85% = 0.85

Student not study = 11% = 0.11

Student who pass = 90% = 0.90

Computation:

P(student not pass) = 1 - 0.85

P(student not pass) = 0.15

probability that student passes = P(Student studies)(Student who pass) + P(Student not study)(student not pass)

probability that student passes = (0.85)(0.90) + (0.15)(0.11)

probability that student passes = 0.765 + 0.0165

probability that student passes = 0.7815

Using the percentages given, it is found that there is a 0.7815 = 78.15% probability that student passes.

The percentages associated with passing the test are given by:

Hence, adding these percentages:

[tex]p = 0.9(0.85) + 0.11(0.15) = 0.7815[/tex]

0.7815 x 100% = 78.15%

There is a 0.7815 = 78.15% probability that student passes.
