The value of the z test statistic will be 2.55.

The z test statistic is a statistical evaluation of a value's correlation to the mean of a collection of values, expressed in terms of standard deviation.

The z test statistics is given as

z = (x – μ) / σ

Where μ is the mean, σ is the standard deviation, and x is the sample.

A sample of 25 provided a sample mean μ = 14 and a sample standard deviation σ = 4.32.

Then the value of the z test statistic will be

z = (x – μ) / σ

z = (25 - 14) / 4.32

z = 11 / 4.32

z = 2.546 ≈ 2.55

Step-by-step explanation:

First, find the circumference of the whole circle.

C=2pir

C=2(3.14)(17)

C=106.76

Then, divide by 2 because a semi-circle is half of a circle.

106.76/2 = 53.38

Therefore, the circumference, or the perimeter, of the semicircle is 53.38

Step-by-step explanation:

The value of cotθ where θ is in fourth quadrant is \(-\frac{5}{\sqrt{171} }\)  which is option (A).

It is given that cosθ = 5 /14 .        ....(1)

As we know that cosθ  = Base / Hypotenuse     ...(2)

On comparing equation (1) and (2) , we get

Base = 5 and Hypotenuse = 14

Using Pythagorean theorem , we get

          Hypotenuse² = Perpendicular² + Base²

                   14²   = P² + 5²

                   196 = P²  +25

                    171 = P²

                   ± \(\sqrt{171}\) = P

Then , cotθ = Base / Perpendicular

                   = ±\(\frac{5}{\sqrt{171} }\)

As in fourth quadrant cotθ is negative so cotθ will be negative.

So , we will consider the negative value .

  Cotθ = - \(\frac{5}{\sqrt{171} }\)

Step-by-step explanation:

The equation of the tangent line at (1,1) is given as follows:

y - 1 = -0.25(x - 1).

The curve for this problem is given as follows:

x² - y² = 2x + y + xy - 4.

Applying implicit differentiation, we obtain the slope of the tangent line, as follows:

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

(dy/dx)(1 + x + 2y) = 2x - 2 - y

m = (2x - 2 - y)/(1 + x + 2y).

At x = 1 and y = 1, the slope is given as follows:

m = (2 - 2 - 1)/(1 + 1 + 2)

m = -0.25.

Hence the point-slope equation is given as follows:

y - 1 = -0.25(x - 1).

Answer:62 7/20

Step-by-step explanation:

The measure of angle O is 56 and the value of m and n are 8.1 in and 14.5 in respectively.

Trigonometric Ratios are defined as the values of all the trigonometric functions based on the value of the ratio of sides in a right-angled triangle. The longest side is hypotenuse and it is the side facing the right angle. The other two sides are opposite and adjascent.

sin(tetha) = opp/hyp

cos(tetha) = adj/hyp

tan,(tetha) = opp/adj

angle O = 180-(90+34)

= 180- 124

= 56°

To find m,

Tan 34 = m/12

m = Tan34 × 12

m = 8.1 in

using Pythagoras theorem to find n,

n= √8.1²+12²

n = √65.61+144

n = √209.61

The cost of one small box of fruit and the cost of one large box of fruit is $11.5 and $14.5 respectively.

Let

cost of one small box of fruit = x

cost of one large box of fruit = y

15x + 15y = 390

20x + 25y = 592.50

From (1)

x + y = 26

x = 26 - y

Substitute x = 26 - y into (2)

20x + 25y = 592.50

20(26 - y) + 25y = 592.50

520 - 20y + 25y = 592.50

- 20y + 25y = 592.50 - 520

5y = 72.50

divide both sides by 5

y = 72.50/5

y = 14.5

Substitute y = 14.5 into

15x + 15y = 390

15x + 15(14.5) = 390

15x + 217.5 = 390

15x = 390 - 217.5

15x = 172.5

divide both sides by 15

x = 172.5/15

x = 11.5

Therefore, small box cost $11.5 and large box cost $14.5

The fraction represented on the number line is equivalent to 2/6 is 1/3.

In Mathematics, fractions are represented as a numerical value, which defines a part of a whole. A fraction can be a portion or section of any quantity out of a whole, where the whole can be any number, a specific value, or a thing.

The given fraction is 2/6.

Now we have to find an equivalent fraction to 2/6

Let us divide both numerator and denominator  by the same number 2.

That is, 2÷2/6÷2

= 1/3

Hence, the equivalent fraction is 1/3.

The mean of the given dataset is 153.5.

The sum of all values divided by the total number of values determines the mean (also known as the arithmetic mean, which differs from the geometric mean) of a dataset. The term "average" is frequently used to describe this measure of central tendency.

Given a data set:

265 190  175  155  145 145  125  125 125  125

(a) To find the mean, we need to add up all the values and divide by the total number of values:

Mean = (265 + 190 + 175 + 155 + 145 + 145 + 125 + 125 + 125 + 125) / 10

Mean = 153.5

(b) To find the median, we need to find the middle value when the data is arranged in order. Since there are 10 values, the median will be the average of the fifth and sixth values:

Median = (145 + 145) / 2

Median = 145

(c) The mode is the value that appears most frequently in the data. In this case, the mode is 125, since it appears four times.

(d) The midrange is the average of the highest and lowest values:

Midrange = (265 + 125) / 2

Midrange = 195

(e) The results tell us that the net worth of all celebrities varies widely, from 125 million dollars to 265 million dollars. The mean and median are both around 150 million dollars, which suggests that the distribution is roughly symmetric.

However, the presence of two modes (125 and 145) suggests that there are multiple sub-groups of celebrities with different net worths.

The value of m∠1 is 103°. The solution has been obtained by using the angle sum property.

What is the angle sum property?

The angle sum property of a triangle states that the sum of the three internal angles of a triangle is 180 degrees.

We are given that m∠5 = 142° and m∠4 = 65°.

Since m∠5 and m∠2 lie on a straight line so, they form a linear pair.

So,

⇒ m∠5 + m∠2 = 180°

⇒ 142° + m∠2 = 180°

⇒ m∠2 = 38°

We know that sum of angles of a triangle is 180°.

So,

⇒ m∠3 + m∠4 + m∠2 = 180°

⇒ m∠3 + 65° + 38° = 180°

⇒ m∠3 + 103° = 180°

⇒ m∠3 = 77°

Now, since m∠3 and m∠1 lie on a straight line so, they form a linear pair.

So,

⇒ m∠3 + m∠1 = 180°

⇒ 77° + m∠1 = 180°

⇒ m∠1 = 103°

Hence, the value of m∠1 is 103°.

Question: Find m∠1 if m∠5 = 142° and m∠4 = 65°.

Answer:

Step-by-step explanation:

By means of recurrence formulas and a given initial value, we find the following three results: f(5) = 19, f(125) = 469, f(3125) = 11719.

Sequences are sets of values defined by at least one condition. In this case, we have three conditions to generate the required values:

f(n) = f(n/5) + 3 · n

f(1) = 4

\(n \in \mathbb{N}\)

Now we proceed to find the elements by recurrence:

f(5) = f(1) + 3 · 5

f(5) = 4 + 15

f(5) = 19

f(25) = f(5) + 3 · 25

f(25) = 19 + 75

f(25) = 94

f(125) = f(25) + 3 · 125

f(125) = 94 + 375

f(125) = 469

f(625) = f(125) + 3 · 625

f(625) = 469 + 3 · 625

f(625) = 469 + 1875

f(625) = 2344

f(3125) = f(625) + 3 · 3125

f(3125) = 2344 + 9375

f(3125) = 11719

By means of recurrence formulas and a given initial value, we find the following three results: f(5) = 19, f(125) = 469, f(3125) = 11719.
