The null hypothesis was not refuted. There is insufficient evidence to support the assertion that male commute times are considerably longer than female commute times (P-value=0.155).

The data is:

Males n1 = 237

M1 = 31.6

s1 = 24.0

Females n2 = 263

M2 = 29.3

s2 = 24.3

This is a hypothesis test for a population mean differences.

According to the assertion, the average daily travel time for men is much longer than the average daily commuting time for women.

The null and alternative hypotheses are then:

\(H_{0}\) = \(\mu_m\) - \(\mu_f\) = 0

\(H_{a}\) = \(\mu_m\) - \(\mu_f\) > 0

The threshold of significance is set at 0.05.

The mean of Sample 1 (males) is 31.6, with a standard deviation of 24.

Sample 2 (females) does have a mean of 29.3 and a standard deviation of 24.3 (n2 = 263).

Md = 2.3 is the difference in sample means.

\(M_{d}\) = \(M_{m}\) - \(M_{f}\)

\(M_{d}\) = 31.6 - 29.3

\(M_{d}\) = 2.3

The formula to calculate the estimated standard error of the difference between the means:

\(S_{Md}\) = √(((σ1)² ÷ (n1)² + ((σ2)² ÷ (n2)²)

\(S_{Md}\) = √((24)² ÷ (237)²) + (24.3)² ÷ (263)²))

\(S_{Md}\) = √(0.0102 + 0.0085)

\(S_{Md}\) = 0.136

the t-statistic as,

t = ((\(M_{d}\) - ( \(\mu_m\) - \(\mu_f\) )) ÷ \(S_{Md}\))

t = ((2.3 - 0) ÷ 0.136)

t = 1.611

The degrees of freedom for this test are:

df = n1 + n2 - 1 = 237 + 263 - 1

df = n1 + n2 - 1 = 499

Because this is a right-tailed test with 499 degrees of freedom and t = 1.611, the P-value is determined as follows (using a t-table):

P - value = P(t > 1.611) = 0.155

The impact is not significant since the P-value (0.155) is greater than the significance threshold (0.05).

As a result, the null hypothesis was not rejected.

The term that refers to the fact that the distance between two or more points is equal is "equidistant".

In geometry, the concept of equidistance is important when dealing with circles, which are sets of points that are equidistant from a single point called the center. This property is what allows circles to be defined in terms of their radius, which is the distance between the center and any point on the circle.

Equidistance is also important in other areas of mathematics and science. For example, in physics, equidistant points can be used to define a plane or surface that is perpendicular to a given line or axis. This is useful in many applications, such as designing electronic circuit boards or constructing buildings.

The concept of equidistance is not limited to mathematics and science, however. It can also be applied in everyday life. For instance, if you are planning a road trip and want to visit several destinations that are equidistant from your starting point, you can use this information to help plan your route and estimate your travel time.

There are 180 different starting lineups that can be created for the college team.To find the number of different starting lineups that can be created for the college team, we need to use the combination formula.

The number of ways to choose k items from a set of n distinct items is given by the formula:

nCk = n! / (k! * (n-k)!)

where "!" denotes the factorial function, which means the product of all positive integers up to that number.

In this case, we want to choose 2 guards out of 5, 2 forwards out of 4, and 1 center out of 3. So the total number of different starting lineups that can be created is:

(5C2) * (4C2) * (3C1)

= (5! / (2! * 3!)) * (4! / (2! * 2!)) * (3! / (1! * 2!))

= (10) * (6) * (3)

Since both triangles are right triangles, we can apply the Pythagorean theorem:

c^2 = a^2 + b^2

Where:

c = hypotenuse ( the longest side )

a & b = the other 2 legs of the triangle

for the left side triangle ( T1 )

9^2 = 6^2 + y^2

Let's label "y" the missing side on triangle 1 , which is a common side for both triangles.

81 = 36 + y^2

81 - 36 = y^2

45 = y^2

√45 = y

Now, with triangle 2:

x^2 = 8^2 + (√45)^2

Solve for x

x ^2 = 64 + 45

x^2 = 109

x = √109 = 10.44

Answer:

x = 14°

Step-by-step explanation:

We know that,

→ Straight line is always 180°.

Forming the equation,

→ 156° + (x + 10°) = 180°

Now the value of x will be,

→ 156° + (x + 10°) = 180°

→ x + 166° = 180°

→ x = 180° - 166°

→ [ x = 14° ]

Hence, the value of x is 14°.

The value of x in the given supplementary angle pair is 14°.

Then,

156 + (x + 10) = 180

166 + x = 180

x = 180 - 166

x = 14°

The correct option is for the value of c,  such that f(c) is the average value of the function on the interval [0, 2], is D.

The average value of a function on an interval [a, b] is given by:

The point does not lie on the center of the circle.

The point (5, 11) does not lie on the circle centered at the origin and containing the point (2, 5√).

The center of the circle in question is the origin (0, 0). The point (2, 5√) lies on the circle, so we need to check if the distance between the origin and (5, 11) is equal to the radius.

To determine if a point lies on a circle, we can calculate the distance between the center of the circle and the given point. If the distance is equal to the radius of the circle, then the point lies on the circle.

The distance between two points in a coordinate plane can be calculated using the distance formula: d = sqrt((x2 - x1)^2 + (y2 - y1)^2).

Calculating the distance between the origin and (5, 11), we have:

d = sqrt((5 - 0)^2 + (11 - 0)^2) = sqrt(25 + 121) = sqrt(146)=12.083.

Since the distance, sqrt(146), is not equal to the radius of the circle, the point (5, 11) does not lie on the circle centered at the origin and containing the point (2, 5√).

Multifactor productivity (MFP) is a measure of how efficiently a company is using its resources. It is calculated by dividing the total output of a company’s production process by the total inputs used.

To calculate the MFP for Telco Inc., we need to first calculate the total output.

The total output is the number of units produced (50,000) multiplied by the cost of materials ($20,000) and the cost of energy ($20).

500000×20000×20= 1000000

This gives us a total output of $1,000,000.

Next, we need to calculate the total inputs used. The total inputs used is the labor rate (2,000) multiplied by the labor hours (4,000) plus the machine rate ($15) multiplied by the machine hours (5,000).

2000×4000+(15×5000)= 105000

This gives us a total input of $105,000. MFP is calculated by dividing the total output by the total inputs used. Therefore, the MFP of Telco Inc. is 1.667.

Answer:

To calculate the surface area and volume of a cylinder, we can use the following formulas:

a) Surface Area of a Cylinder:

The surface area of a cylinder consists of two circles (top and bottom) and the curved surface area.

The formula for the surface area of a cylinder is:

SA = 2πr² + 2πrh

Where:

SA = Surface Area

r = Radius of the base (half the diameter)

h = Height of the cylinder

Given that the diameter is 16 yards, the radius is half of that, so r = 8 yards. The height is 20 yards.

Substituting the values into the formula, we get:

SA = 2π(8)² + 2π(8)(20)

= 2π(64) + 2π(160)

= 128π + 320π

= 448π

So, the surface area of the cylinder is 448π square yards.

b) Volume of a Cylinder:

The formula for the volume of a cylinder is:

V = πr²h

Using the same values for the radius (r = 8 yards) and height (h = 20 yards), we can calculate the volume:

V = π(8)²(20)

= 64π(20)

= 1280π

The volume of the cylinder is 1280π cubic yards.
