The correct answer is a) No you cannot, because the lower boundary of the confidence interval is .131, which is less than .30, and so the true correlation could be less than .30.

Correlation analysis allows us to examine the strength, direction, and nature of the relationship between two variables, and to determine whether or not there is a statistically significant association between them.

Based on the information given, there appears to be a positive correlation between time spent exercising and test scores. This means that as the time spent exercising increases, the test scores also tend to increase. However, we cannot determine the strength or causality of this correlation without additional information or analysis. It is possible that other factors could be influencing both variables or that there could be confounding variables affecting the relationship.

The sorting algorithms that are not comparison based are counting sort, bucket sort, and radix sort.

Counting sort works by counting the number of occurrences of each element in an array and then using this information to determine the position of each element in the sorted array.

Bucket sort works by dividing the array into a number of smaller arrays, called buckets, and then sorting each of these smaller arrays separately.

Radix sort works by sorting the elements of an array based on the individual digits of each element, starting with the least significant digit and working up to the most significant digit.

These algorithms do not rely on comparisons between elements, which is why they are not considered comparison based.

The value of f(1) will be 45.

A relationship between a group of inputs and one output is referred to as a function. In plain English, a function is an association between inputs in which each input is connected to precisely one output. A domain, codomain, or range exists for every function. Typically, f(x), where x is the input, is used to represent a function.

Given a function f(n) = 45.(4/5)ⁿ⁻¹

To calculate the value of f(1) we will substitute the value of the n by 1.

f(1) = 45.(4/5)¹⁻¹

f(1) = 45.(4/5)⁰

f(1) = 45

To calculate the value of f(n -1) we will substitute the value of the n by

n - 1.

f(n -1) = 45.(4/5)ⁿ⁻¹⁻¹

that can also be written as, from the rule of power

f(n -1) = (45.(4/5)ⁿ⁻¹)/4/5

f(n -1) = (45.(4/5)ⁿ⁻¹) * 5/4

f(n -1) = f(n) * 5/4

so,

f(n) = f(n-1) * 4/5

Therefore, the value of f(1) will be 45, and the value of f(n) = f(n-11)*4/5.

Barbara will therefore shell out $171.36 for the cost of shipping and handling.

The amount of money, or its equivalent, for which anything being offered for sale, purchased, or otherwise transacted. A price on someone's head is a sum provided for their capture, whether they are alive or dead.

We must calculate 28% of the chandelier's original purchase price in order to calculate the value Sarah will charge for shipping and handling.

Step 1

Calculate 28% of $612

We can multiply a value by 0.28 to get 28% of it, or reduce it by 100 & then multiply the result by 28. So:

28% of $612 = 0.28 x $612 = $171.36

Step 2

Add the cost of shipping and handling to the purchase price.

Yes You can buy 24 apples for $0.125 per pound. This price will not available except in festival or discounts sale.

what are ounces ?

An ounce is a unit of weight or mass commonly used in the United States and other countries. It is usually abbreviated as oz. One ounce is equal to 1/16th of a pound or approximately 28.35 grams. Ounces are often used to measure small quantities of food or ingredients in recipes, as well as for measuring the weight of small objects.

According to the question:

To determine whether you can buy 24 apples for $9, we need to find the cost per apple.

If 24 apples cost $9, then the cost per apple is:

$9 / 24 apples = $0.375 per apple

Since each apple weighs about 5 ounces, there are about 3 apples per pound:

16 ounces / 5 ounces per apple ≈ 3.2 apples per pound

Therefore, the cost per pound of apples is:

The measure of the angle m∠C = m∠H is equal to 35°.

We know two similar planer figures are congruent when we have sides or angles or both that are the same as the corresponding sides or angles or both.

Given, Triangle ABC is similar to triangle FGH.

Therefore, m∠A = m∠F = 63° and m∠B = m∠G = 82°.

We know the sum of the measure of all the interior angles in a triangle is 180°.

Therefore, m∠C = m∠H = 180° - 63° - 82° = 35°.

Angle CAB is in a triangle which means all the angles add up to 180 degrees and the value of this angle is:

= 180 - 80 - 57 = 43 degrees

The value of DAC would then be;

= 180 - EAD - CAB

With the thickness of a flange on an aircraft component is uniformly distributed between 0.95 and 1.05 millimeters.

a) 40% of the flanges exceeds 1.01 millimeters.

b) 1.04 millimeters is the thickness that is exceeded by 90% of the flanges.

c) The mean of flange thickness is 1 millimeters and the variance of flange thickness is 0.01 millimeters^2.

a) To determine the proportion of flanges that exceeds 1.01 millimeters, we need to find the area under the probability density function (pdf) of the thickness that is greater than 1.01 millimeters.

Let's call the random variable X representing the thickness of the flange. The pdf of X is uniform, so it has constant value over the interval [0.95, 1.05]. Therefore, the proportion of flanges that exceeds 1.01 millimeters can be found as follows:

P(X > 1.01) = (1.05 - 1.01) / (1.05 - 0.95) = (1.05 - 1.01) / 0.1 = 0.04 / 0.1 = 0.4

So, 40% of the flanges exceed 1.01 millimeters.

b) To find the thickness that is exceeded by 90% of the flanges, we need to solve for X in the following equation:

P(X > X) = 0.9

Substituting the values for the pdf, we get:

(X - 0.95) / (1.05 - 0.95) = 0.9

Solving for X, we get:

X = 0.95 + 0.9 * (1.05 - 0.95) = 0.95 + 0.9 * 0.1 = 0.95 + 0.09 = 1.04

So, 1.04 millimeters is the thickness that is exceeded by 90% of the flanges.

c) The mean of X can be calculated as follows:

Mean = (0.95 + 1.05) / 2 = 1

The variance of X can be calculated as follows:

Variance = (1.05 - 0.95)^2 / 12 = 0.01

So, the mean and variance of flange thickness are:

Mean = 1 millimeters

Variance = 0.01 millimeters^2

To get the solution, we have to solve for the area of the square shape and the area of the circle

The area of a square is given as A = a²

We would have area of remaining fabric as

a² -  πr²

The square has its sides as a = 9 cm

Answer:W+6

Step-by-step explanation:

The circles with the specified angle of internal sectors, indicates that we get the following arc and radial lengths;

2. m∠ADC = 160°

m∠BDC = 160°

3. Length of [tex]\widehat{CB}[/tex] ≈ 11.17 inches

4. Length of [tex]\widehat{ABC}[/tex] ≈ 13.96 inches

5. a. The radius of ⊙ Q ≈ 14.324 inches

The radius is the straight line extending from the circle center to the circumference. The radius is the shortest distance from the circle center to the circumference of the circle.

Angle ∠ADC is congruent to ∠BDC in the circle with center D

∠ADC ≅ ∠BDC

2. ∠ADC ≅ ∠BDC, therefore;

m∠ADC = m∠BDC

The angle sum property of the angle at the center of a circle, indicates that we get;

40° + m∠ADC + m∠BDC = 360°

Therefore by plugging in m∠ADC = m∠BDC, we get;

40° + m∠ADC + m∠ADC = 360° (substitution property)

40° + 2 × m∠ADC = 360°

2 × m∠ADC = 360° - 40° = 320°

m∠ADC = 320° ÷ 2 = 160°

m∠ADC = 160° = m∠BDC

m∠BDC = 160°

3. The length of the arc [tex]\widehat{CB}[/tex], can be obtained from the proportion of the circumference of the circle D represented by the sector BDC as follows;

Length of the arc [tex]\widehat{CB}[/tex] = ((m∠BDC)/360°) × 2·π·r

Where;

r = The radius of the circle

The radius of the circle, r = 4 inches

Therefore; Length of the arc [tex]\widehat{CB}[/tex] = (160°/360°) × 2 × π × 4 ≈ 11.17

4. The length of the arc [tex]\widehat{ABC}[/tex] can be found as follows;

The angle at the center of the arc [tex]\widehat{ABC}[/tex] = 40° + m∠BDC

Therefore; The angle at the center of the arc [tex]\widehat{ABC}[/tex] = 40° + 160° = 200°

5. The length of the arc [tex]\widehat{AB}[/tex] = 15 inches

The angle formed by the sides AQ and BQ of the sector AQB = 60°

Therefore, we get;

length of the arc [tex]\widehat{AB}[/tex] = (60°/360°) × 2 × π × r = 15 inches

r = 15/((60°/360°) × 2 × π) ≈ 14.324
