b. Is there sufficient evidence to conclude that there is a linear correlation the two variables?

Answer:

Step-by-step explanation:

we have several angles that have the same vertex and so they are congruent

1) e = 35 degrees because the opp angle has this measure

2) d = 109 degrees for the reason above

3) for find f we have to notice that the sum of the three angles (if you look at the vertical line you can notice that it is a straight line, so describes two angles whose measures are 180 degrees)

f = 180 - (35 + 109)

f = 180 - 144 = 36 degrees

Answer:

D. 96 inches.

Step-by-step explanation:

Radius of cylinder = 1/2 * 24 = 12 inches.

Radius of the cone = 1/2 * 12 = 6 inches.

Volume of the cylinder = pi r^2 h and volume of the cone = 1/3 pi r^2 h

So pi 12^2 * 8 = 1/3 pi * 6^2 * h

1152 pi = 12 pi h

h = 1152/12

h = 96 inches.

The length of the guy wire is approximately 74.7 feet, and the height of the antenna is approximately 72.2 feet.

Here, we have,

To find the length of the guy wire and the height of the antenna, we can use trigonometry and the concept of right triangles.

In this scenario, the guy wire represents the hypotenuse of a right triangle, and the height of the antenna represents one of the legs of the triangle.

The angle of elevation formed by the guy wire is given as 79 degrees.

Let's denote the length of the guy wire as h and the height of the antenna as a.

Using the trigonometric function sine (sin), we can relate the angle of elevation and the sides of the triangle:

sin(angle) = opposite/hypotenuse.

In this case, the opposite side is the height of the antenna (a), and the hypotenuse is the length of the guy wire (h).

sin(79°) = a/h.

To solve for h, we can rearrange the equation as:

h = a / sin(79°).

We also have another relationship between the sides of the triangle.

The base of the right triangle is given as 15 feet, and the height of the antenna is a.

Therefore, using the Pythagorean theorem, we have:

h² = a² + 15².

Now we can substitute the expression for h from the first equation into the second equation:

(a / sin(79°))² = a² + 15².

Expanding and simplifying, we get:

a² / sin²(79°) = a² + 225.

Multiplying both sides of the equation by sin²(79°), we have:

a² = sin²(79°) * (a² + 225).

Expanding again, we get:

a² = sin²(79°) * a² + 225 * sin²(79°).

Rearranging the equation, we have:

a² - sin²(79°) * a² = 225 * sin²(79°).

Factoring out a², we get:

(1 - sin²(79°)) * a² = 225 * sin²(79°).

Using the trigonometric identity sin²(θ) + cos²(θ) = 1,

we know that cos²(θ) = 1 - sin²(θ).

Therefore:

cos²(79°) * a² = 225 * sin²(79°).

Taking the square root of both sides, we have:

cos(79°) * a = 15 * sin(79°).

Simplifying, we get:

a = (15 * sin(79°)) / cos(79°).

Using a calculator or software, we find:

a ≈ 72.2 feet (rounded to one decimal place).

Now, to find the length of the guy wire (h), we can substitute the value of a into the first equation:

h = a / sin(79°).

Using a calculator or software, we find:

h ≈ 74.7 feet (rounded to one decimal place).

Therefore, the length of the guy wire is approximately 74.7 feet, and the height of the antenna is approximately 72.2 feet.

Answer:

  9 weeks

Step-by-step explanation:

In problems of this nature, the usual assumption is that the time required is proportional to the work product and inversely proportional to the number of people doing the job. Here, there is no change in the amount of work, but the number of people is reduced by a factor of 12/18 = 2/3.

So, the amount of time required is expected to increase by a factor of 1/(2/3) = 3/2.

  (6 weeks)×(3/2) = 9 weeks

It would have taken 9 weeks to sew the 540 dresses.

There are 26 alphabet and 10 digits then the number of the possible ID codes will be 67600.

A permutation is an act of arranging the objects or elements in order. Combinations are the way of selecting objects or elements from a group of objects or collections, in such a way the order of the objects does not matter.

A company is making aid badges with personal ID codes on them for each employee.

The ID code will consist of two letters followed by 2 digits.

Then the number of ways ID codes are there will be

Step-by-step explanation:

V= 51 Degrees (has told in the question)

U= 90 Degrees (Its A Right Angel Triangle, And Right Angle Is Always 90 Degrees)

W= 39 Degrees (Sum Of All Sides Of A Triangle = 180 Degrees

                           51 + 90 + W = 180

                           141 + W = 180

Step-by-step explanation:

The dimensions of the dollhouse bed are 3.6 inches × 6 inches. By dividing 10 by each dimension, the dollhouse bed's dimensions may be found.

Dilation is the process of increasing the size of an item without affecting its form. Depending on the scale factor, the object's size can be raised or lowered.

The dimension of real bad;

a = 36 inches

L = 60 inches

Down scale factor = 1/10

The dimensions of the dollhouse bed are obtained by dividing 10 in each dimension;

a'=36/10

a'=3.6 inches

L'=60/10

L'=6 inches

Hence the dimensions of the dollhouse bed are 3.6 inches × 6 inches.

f = 19.0

Step-by-step explanation:

By applying sine rule in the triangle given in the figure,

By applying triangle sum theorem,

m∠F + m∠G + m∠H = 180°

110° + m∠G + 40° = 180°

m∠G + 150° = 180°

m∠G = 30°

Answer:

(155.301 ; 159.299)

Step-by-step explanation:

Xbar = 157.3

Sample size, n = 234

Population standard deviation, σ = 15.6

The confidence interval :

Xbar ± standard Error

Standard Error = Zcritical * σ/√n

Zcritical at 95% = 1.96

Standard Error = 1.96 * (15.6/√234) = 1.999

Lower boundary : 157.3 - 1.999 = 155.301

Upper boundary : 157.3 + 1.999 = 159.299
