2)

Z distribution.

3)

Generally, the equation for is mathematically given as

Solutions

we have, \($u=300$$$\begin{aligned}& \sigma=150 \text { dollars } \\N &=64 \text { individuals } \\\bar{x} &=255 \text { dollare. } \\a=& 0.05 .\end{aligned}\)

(1):

H0: M \(\geqslant\) 300 dollars;  customers save at least 300 dollars per year by switching to them.

H0: M \(\geqslant\) 300 dollars:

(This is a left-tailed test)

(2):

when \(\sigma\) is known, we use the Z test. we use Z distribution.

(3):

\(\begin{gathered}z=\frac{\bar{x}-\mu}{6 / \sqrt{n}}=\frac{255-300}{150 / \sqrt{64}}=\frac{-45}{18.75}=-2.4 \\z=-2.4\end{gathered}\)

(4):

\(Pvalue $=P(z < -2 \cdot 4)$ $=0.0082 \quad\{$ wing $z$ tables $\}$ \\\\\text { Pvalue }=0.0082\)

(5):

In conclusion, Since p-value = 0·0082 <0.05

This is statistically significant at the 0.05 level.

We thus "Refect H0" using a threshold of significance of 0.05.

"H0" is rejected as a hypothesis with a level of significance of 0.05.

There is not enough data to support the assertion that consumers may save at least $300 annually by switching insurance providers.

The expected value of a $2 ticket is $0.63

To calculate the expected value of a $2 ticket, we need to multiply the probability of winning by the value of the prize, then sum those products:

The Probability of winning the grand prize = 1/2000

Product: (1/2000) x $500 = $0.25

The Probability of winning a secondary prize: 3/2000

Product: (3/2000) x $200 = $0.30

The Probability of winning a third level prize: 8/2000

Product: (8/2000) x $20 = $0.08

The sum of the products:

$0.25 + $0.30 + $0.08 = $0.63

So the expected value of a $2 ticket is $0.63, meaning that on average, a person can expect to win $0.63 for every $2 they spend on a ticket.

The charity is expected to make a profit, which is why the answer is negative.

That is -$2 + $0.63 = -$1.37

So the expected profit for the charity per ticket sold is -$1.37, which is approximately the same as the given answer of negative $1.358(rounding off)

The 99% confidence interval for the true population mean backpack weight is approximately (68.15, 71.85) ounces, rounded to two decimal places.

To construct a 99% confidence interval for the true population mean backpack weight, we can use the formula:Confidence Interval = Sample Mean ± (Critical Value * Standard Deviation / √Sample Size).

Since the population standard deviation is known, we can use the z-distribution and find the critical value corresponding to a 99% confidence level. The critical value for a 99% confidence level is approximately 2.576.

Given that the sample mean weight is 70 ounces, the population standard deviation is 6.4 ounces, and the sample size is 48, we can calculate the confidence interval:

Confidence Interval = 70 ± (2.576 * 6.4 / √48).

Simplifying the expression, we get:

Confidence Interval ≈ 70 ± 1.855.

Step-by-step explanation:

The maximum error in the calculated area of the disk is 26.39 cm². The percentage error is 3.73%. (Round your answer to two decimal places.)

The radius of a circular disk is given as 15 cm with a maximum error in measurement of 0.28 cm.

Use differentials to estimate the maximum error in the calculated area of the disk.

We know that the formula for the area of a circle is given by:

A = πr²

where r is the radius of the circle.

Using differentials, we have:

dA = 2πrdr

Substituting the given values:

r = 15 cm and dr = 0.28 cmdA = 2π(15)(0.28)dA ≈ 26.39 cm²

Therefore, the maximum error in the calculated area of the disk is 26.39 cm².

The relative error is given by the formula:

Relative error = (Error in measurement / Actual value) × 100%

The actual value of the area of the disk is given by:

A = π(15)²A = 706.86 cm²

Substituting the values we calculated earlier, we have:

Relative error = (26.39 / 706.86) × 100%

Relative error ≈ 3.73%

Therefore, the relative error is approximately 3.73%.

The percentage error is the same as the relative error, which is 3.73%.

Therefore, the percentage error is 3.73%.

Given:

The graph of a line a.

To find:

The slope of the line a.

Solution:

Slope formula:

\(m=\dfrac{y_2-y_1}{x_2-x_1}\)

From the given graph it is clear that the line a passes through the points (-1,1) and (0,-2). So, the slope of the line a is:

\(m=\dfrac{-2-1}{0-(-1)}\)

\(m=\dfrac{-3}{1}\)

\(m=-3\)

The slope of the line a is -3. Therefore, the correct option is C.

The final result of the integral is:

∫ (log(1 + x²) / (x + 1)²) dx = log(x + 1) - 2 (log(x + 1) / x) - 2Li(x) + C,

where Li(x) is the logarithmic integral function and C is the constant of integration.

We have,

To solve the integral ∫ (log(1 + x²) / (x + 1)²) dx, we can use the method of substitution.

Let's substitute u = x + 1, which implies du = dx. Making this substitution, the integral becomes:

∫ (log(1 + (u-1)²) / u²) du.

Expanding the numerator, we have:

∫ (log(1 + u² - 2u + 1) / u²) du

= ∫ (log(u² - 2u + 2) / u²) du.

Now, let's split the logarithm using the properties of logarithms:

∫ (log(u² - 2u + 2) - log(u²)) / u² du

= ∫ (log(u² - 2u + 2) / u²) du - ∫ (log(u²) / u²) du.

We can simplify the second integral:

∫ (log(u²) / u²) du = ∫ (2 log(u) / u²) du.

Using the power rule for integration, we can integrate both terms:

∫ (log(u² - 2u + 2) / u²) du = log(u² - 2u + 2) / u - 2 ∫ (log(u) / u³) du.

Now, let's focus on the second integral:

∫ (log(u) / u³) du.

This integral does not have a simple closed-form solution in terms of elementary functions.

It can be expressed in terms of a special function called the logarithmic integral, denoted as Li(x).

Therefore,

The final result of the integral is:

∫ (log(1 + x²) / (x + 1)²) dx = log(x + 1) - 2 (log(x + 1) / x) - 2Li(x) + C,

where Li(x) is the logarithmic integral function and C is the constant of integration.

In order to solve this system of linear equations, we just have to isolate one of the variables in one of the equations, then replace it into the other equation and solve for one of the variables, like this:

By taking the first equation and solveing for y, we get:

4x + y = 8

4x - 4x + y = 8 - 4x

0 + y = 8 - 4x

y = 8 - 4x

Now, let's replace 8 - 4x for y into the second equation:

2x - 3y = 4

2x - 3×(8 - 4x) = 4

2x - 3 ×8 - 3×4x = 4

2x - 24 + 12x = 4

Now combine like terms and solve for x:

2x + 12x - 24 = 4

14x - 24 = 4

14x - 24 + 24 = 4 + 24

14x = 28

14x/14 = 28/14

x = 2

Now that we know the value of x, we can replace it into y = 8 - 4x to get the value of y, like this:

y = 8 - 4×2

y = 8 - 8 = 0

Then, y equals 0.

Since these equations are independent of each other we can say that there is exactly one solution, and that is (2,0), the correct answer is option C

Answer:

i) Consecutive interior angles

ii) Supplementary angles

iii) The two oars are parallel by consecutive interior angles theorem

Step-by-step explanation:

i) m∠1  and m∠2 lie between two line and on the same side of the line passing through the two lines. Therefore, they are consecutive interior angles

ii)x = 10

m∠1 = 6x + 18

= 6(10) + 18

= 60 + 18

= 78

m∠2 = 9x + 12

= 9(10) + 12

= 90 + 12

= 102

m∠1 + m∠2 = 72 + 108 = 180

Since m∠1 and m∠2 add to 180, they are supplementary angles.

iii) The two oars are parallel

consecutive interior angle theorem:

If  a transversal cuts through two line and the consecutive interior angles are supplimentary, then the two lines are parallel

The volume of the solid formed when this region is rotated around the y-axis is V = ∫[1,9] π(8 - y/2)² dy cubic units

Volume is a measure of the amount of three-dimensional space that a solid object occupies.

To find the volume of the solid formed when the region is rotated around the y-axis, we need to use the disk method. This involves slicing the solid into thin disks perpendicular to the y-axis and adding up the volumes of all the disks.

Each disk will have a thickness of dy and a radius of x, which can be expressed in terms of y. We can find the radius of each disk by considering the distance between the y-axis and the edge of the region. Since the region is in quadrant i, we know that the edge of the region is at x = 0 (the y-axis) and x = 6 (the right boundary of the region). Therefore, the radius of each disk is given by x = 6 - (y - 5)/2, or equivalently, x = 8 - y/2.

The area of each disk is given by the formula for the area of a circle, A = πr². Substituting our expression for x into this formula, we get

=> A = π(8 - y/2)².

To find the volume of the solid, we need to integrate the area of each disk over the range of y values that covers the region. Since the region has centroid (3,5) and area 12 square units, we know that the region must extend from y = 1 to y = 9. Therefore, the volume of the solid is given by the integral:

V = ∫[1,9] π(8 - y/2)² dy cubic units

Evaluating this integral will give us the volume of the solid formed by rotating the region around the y-axis.
