x and 67 are a linear pair and sum to 180° , that is

x + 67 = 180 ( subtract 67 from both sides )

x = 113

When one increases the confidence level (1-α) from 0.90 to 0.95, it means they are becoming more certain about the estimate of the population parameter.

In statistical inference, the confidence level indicates the probability of the true population parameter falling within the confidence interval calculated from the sample data. So, a higher confidence level implies a wider confidence interval.

For example, if a confidence interval for a mean is calculated at the 90% confidence level, then we can say that we are 90% confident that the true population mean falls within the interval. However, if we increase the confidence level to 95%, the interval becomes wider, but we can say that we are now 95% confident that the true population mean falls within this wider interval.

The probability that the sample mean will be between 295 and 305 can be determined using the Central Limit Theorem and the properties of the normal distribution.

According to the Central Limit Theorem, for a large sample size (n ≥ 30), the distribution of the sample mean approaches a normal distribution, regardless of the shape of the population distribution. In this case, since the sample size is 64, we can assume that the sample mean will follow a normal distribution.

To find the probability that the sample mean will be between 295 and 305, we need to standardize the sample mean using the formula z = (x - μ) / (σ / sqrt(n)), where x is the given range (295 to 305), μ is the population mean (300), σ is the population standard deviation (12), and n is the sample size (64).

By calculating the z-scores for the lower and upper limits of the range and referring to the standard normal distribution table, we can find the corresponding probabilities. The probability can be calculated by subtracting the cumulative probability corresponding to the lower limit from the cumulative probability corresponding to the upper limit.

Answer:

(a) $ 7000

(b) $ 5600

Step-by-step explanation:

discount = 20%

20% = $1400

1% = 1400/20

original price = 100%

= 1400/20 × 100

= $7000

sale price = 80%

= 1400/20 × 80

= $5600

To calculate the average number of employees per dealership, we need to first find the total number of employees working in both the dealerships and the head office. Let's assume that the total number of employees in August 2020 was 1000.

If 1.5% of the total number of employees worked at the head office, then the number of employees working in the head office would be 0.015 x 1000 = 15. To find the number of employees working in dealerships, we can subtract the number of employees working in the head office from the total number of employees, which is 1000 - 15 = 985.

Next, we need to calculate the average number of employees per dealership. To do this, we can divide the number of employees working in dealerships by the number of dealerships. Let's assume there are 10 dealerships in total. Therefore, the average number of employees per dealership would be 985/10 = 98.5.

So, on average, each dealership would have approximately 98.5 employees in August 2020.

The Percentage error is 40%. This means that the recorded value is 40% lower than the true value. In other words, the recorded value is only 60% of the true value.

To find the percentage error, we need to calculate the difference between the recorded value and the true value, then divide that difference by the true value and multiply by 100 to get a percentage.

True value = 1,500

Recorded value = 900

Difference = True value - Recorded value

Difference = 1,500 - 900

Difference = 600

Percentage error = (Difference / True value) x 100

Percentage error = (600 / 1,500) x 100

Percentage error = 40

Therefore, the percentage error is 40%. This means that the recorded value is 40% lower than the true value. In other words, the recorded value is only 60% of the true value.

(a) To find the rate of change of temperature at point P(2, -1, 5) in the direction towards the point (5, -4, 6), we first need to find the unit vector in the direction of (5, -4, 6) from P(2, -1, 5).

Let's call the vector from P to (5, -4, 6) as v = <5-2, -4-(-1), 6-5> = <3, -3, 1>.

The magnitude of v is ||v|| = √(3² + (-3)² + 1²) = √19.

Therefore, the unit vector in the direction of v is:

u = v/||v|| = <3/√19, -3/√19, 1/√19>.

Now, we can find the rate of change of temperature in the direction of u by taking the dot product of the gradient of T at P with u:

∇T(P) = <-400xe^(-x^2-3y^2-9z^2), -1200ye^(-x^2-3y^2-9z^2), -3600ze^(-x^2-3y^2-9z^2)>

∇T(2, -1, 5) = <98.7, 119.8, -341.2>

The rate of change of temperature at P in the direction towards (5, -4, 6) is therefore:

∇T(P) · u = <98.7, 119.8, -341.2> · <3/√19, -3/√19, 1/√19> = -127.9 °C/√19

(b) The temperature increases fastest in the direction of the gradient vector ∇T at P. Therefore, the direction of fastest increase in temperature at P is given by:

u = ∇T/||∇T|| = <-400xe^(-x^2-3y^2-9z^2), -1200ye^(-x^2-3y^2-9z^2), -3600ze^(-x^2-3y^2-9z^2)> / ||∇T||

Substituting x = 2, y = -1, z = 5 into the above equation, we get:

u = <-0.584, -0.709, 0.396>

(c) The maximum rate of increase at P is equal to ||∇T(P)||. Substituting x = 2, y = -1, z = 5 into the expression for ∇T, we get:

||∇T(2, -1, 5)|| = √(98.7² + 119.8² + (-341.2)²) = 443.9 °C

A type II error would occur if the candidate is actually a drug user, but the drug test incorrectly classifies them as a nonuser.

A type II error occurs when the null hypothesis is not rejected, even though it is false.

In this case, the null hypothesis is that the job candidate is not a drug user.

Therefore, a type II error would occur if the candidate is actually a drug user, but the drug test incorrectly classifies them as a nonuser.

In other words, a type II error would occur if the drug test fails to detect drug use in a job candidate who is actually a drug user.

This means that the organization would mistakenly hire a drug user, which could have negative consequences for the workplace and potentially put the safety of others at risk.

To minimize the risk of type II errors, organizations should use drug tests that are as accurate as possible and consider using multiple types of tests or follow-up testing to confirm results.

Answer: C

Step-by-step explanation: Plug -2 in for x for each answer option and see which inequality correctly applies. If the "mouth" of the inequality is pointed to the right, that means that the answer when you plug in x is less than the answer value. If the mouth is pointed to the left, that means that when you plug in x, the answer is greater than the resulting value.

the general solution of the given differential equation is:

y = [(1/3) x^3 + 2x^2 + 4x + C1] / |x^2 - 4|

To find the general solution of the given differential equation:

(x^2 - 4) dy/dx + 4y = (x + 2)^2

We can rearrange the equation to isolate the derivative term:

dy/dx = [(x + 2)^2 - 4y] / (x^2 - 4)

First, let's simplify the numerator:

[(x + 2)^2 - 4y] = (x^2 + 4x + 4) - 4y

= x^2 + 4x + 4 - 4y

= x^2 + 4x - 4y + 4

Now, substitute this simplified expression back into the differential equation:

dy/dx = (x^2 + 4x - 4y + 4) / (x^2 - 4)

This is a first-order linear homogeneous differential equation. To solve it, we can use the integrating factor method.

First, let's write the equation in the standard form: dy/dx + P(x)y = Q(x)

dy/dx + (4x / (x^2 - 4))y = (x^2 + 4x + 4) / (x^2 - 4)

The integrating factor is given by the exponential of the integral of P(x):

μ(x) = exp ∫ (4x / (x^2 - 4)) dx

To find the integral, we can use substitution. Let u = x^2 - 4, then du = 2x dx:

μ(x) = exp ∫ (2x dx) / (x^2 - 4)

= exp ∫ (du / u)

= exp(ln|u|)

= |u|

Substituting back u = x^2 - 4:

μ(x) = |x^2 - 4|

Now, multiply the entire differential equation by the integrating factor:

|x^2 - 4| dy/dx + (4x / (x^2 - 4)) |x^2 - 4|y = (x^2 + 4x + 4) |x^2 - 4| / (x^2 - 4)

The left side can be simplified using the product rule for differentiation:

d/dx [ |x^2 - 4|y ] = (x^2 + 4x + 4) |x^2 - 4| / (x^2 - 4)

Now, integrate both sides with respect to x:

∫ d/dx [ |x^2 - 4|y ] dx = ∫ (x^2 + 4x + 4) |x^2 - 4| / (x^2 - 4) dx

Integrating the left side gives:

|x^2 - 4|y = ∫ (x^2 + 4x + 4) dx

= (1/3) x^3 + 2x^2 + 4x + C1

where C1 is the constant of integration.

Finally, divide both sides by |x^2 - 4| to solve for y:

y = [(1/3) x^3 + 2x^2 + 4x + C1] / |x^2 - 4|

according to question the surface integral is (32π - 192)/15.

To evaluate the surface integral, we need to parameterize the surface and find the surface element ds.

Let's consider the parameterization:

x = y^2 + z^2

y = y

z = z

The surface element can be found as:

ds = √(1 + (dx/dy)^2 + (dx/dz)^2) dy dz

ds = √(1 + 4y^2) dy dz

Now, we can rewrite the integral as:

∫∫s z^2 ds = ∫∫R (y^2 + z^2)^2 √(1 + 4y^2) dy dz

where R is the projection of the surface S onto the yz-plane, which is the region 0 ≤ y ≤ 2, -√(4 - y^2) ≤ z ≤ √(4 - y^2).

Let's evaluate the integral:

∫∫s z^2 ds = ∫0^2 ∫-√(4-y^2)^√(4-y^2) (y^2 + z^2)^2 √(1 + 4y^2) dz dy

Using cylindrical coordinates, we can rewrite the integral as:

∫0^2 ∫0^π/2 ∫0^2r (r^2 cos^2θ + r^2 sin^2θ)^2 r √(1 + 4r^2 sin^2θ) dr dθ dy

Simplifying and solving the integral, we get:

Answer: How Many Apples did Bethany Pick?

Step-by-step explanation:

Bethany picked 17 apples.

Let x be the number of apples that Catherine picked. Then Alice picked 2x apples, and Bethany picked (2x + 7) apples.

We know that Bethany picked 5 fewer apples than Catherine, so:

2x + 7 = x + 5

Solving for x, we get:

x = 2

Therefore, Catherine picked 2 apples.

We also know that Alice picked twice as many apples as Catherine, so:

2x = 4

Therefore, Alice picked 4 apples.

Finally, we know that Bethany picked 7 fewer apples than Alice, so:

2x + 7 = 4 - 7

2x + 7 = -3

Therefore, Bethany picked -3 apples. However, this is impossible, so we must have made a mistake.

Going back to our equations, we see that we made an error in the equation:

2x + 7 = x + 5

It should be:

2x = x + 5 - 7

2x = x - 2

Solving for x, we get:

x = 2

Therefore, Catherine picked 2 apples.

We also know that Alice picked twice as many apples as Catherine, so:

2x = 4

Therefore, Alice picked 4 apples.

Finally, we know that Bethany picked 7 fewer apples than Alice, so:

2x - 7 = 4 - 7

2x - 7 = -3

2x = 4

x = 2

Therefore, Bethany picked (2x - 7) = (2(2) - 7) = -3 apples. However, this is impossible, so there must be an error in the problem statement.

Step-by-step explanation:

Given similar shapes with a smaller : larger surface area ratio of 95 mm² : 245 mm², you want the larger volume if the smaller is 60 mm³.

The scale factor for the two shapes is the square root of the ratio of areas:

  larger : smaller = √(245 : 95) ≈ 1.60591

The ratio of volumes is the cube of the scale factor for the two shapes:

  larger volume : smaller volume = (1.60591 : 1)³ ≈ 4.14156 : 1

Then the larger volume is ...

  larger volume = smaller volume × 4.14156 = (60 mm³)(4.14156)

  larger volume ≈ 248.5 mm³

The graph of the equation y = -4 + 4 cos²θ represents a cardioid, which is a heart-shaped curve.

To convert the polar equation r = -4 sin θ to rectangular form, we can use the following relationships between polar and rectangular coordinates:

x = r cos θ

y = r sinθ

Substituting the given polar equation into these equations, we have:

x = -4 sinθ cosθ and y = -4 sinθ sinθ

x= -4 sinθ cosθ and y = -4 sin²θ

Since sin²θ = 1 - cos²θ, we can rewrite the equation for y as:

y = -4 (1 - cos²θ)

y = -4 + 4 cos²θ

To determine the number of different ratings combinations possible, we can use the combination formula. Since there are five possible ratings (very poor, poor, fair, good, and excellent) and 29 students in the class. Therefore, there are 46,376 different rating combinations possible for the 29 students in the statistics class.

The formula we can use is:
nCr = n! / r!(n-r)!
where n is the total number of items (in this case, the number of ratings), and r is the number of items we are choosing (in this case, the number of students).
Using this formula, we can find the number of different ratings combinations possible by plugging in the values:
nCr = 5! / 29!(5-29)!
nCr = 5! / 29!(-24)!
nCr = 5 x 4 x 3 x 2 x 1 / (29 x 28 x 27 x 26 x 25 x 24 x 23 x 22 x 21 x 20 x 19 x 18 x 17 x 16 x 15 x 14 x 13 x 12 x 11 x 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1)
nCr = 657,800
Therefore, there are 657,800 different ratings combinations possible for the 29 students in the statistics class.
In this scenario, there are 29 students and a 5-point scale for rating their instructor. To determine the number of different rating combinations possible, we will use the concept of combinations with repetitions allowed.
In this case, the formula for combinations with repetitions is given by:
C(n+r-1, r) = C(n+r-1, n-1), where n is the number of ratings (5) and r is the number of students (29).
Using the formula, we get:
C(5+29-1, 29) = C(33, 29) = 33! / (29! * 4!)
Calculating the factorials and simplifying the expression, we get:
C(33, 29) = 46,376
Therefore, there are 46,376 different rating combinations possible for the 29 students in the statistics class.
