To answer the first question, the spinner has only two colors: green and blue. The probability of landing on green is given by the ratio of the number of green sections to the total number of sections.

1. Probability of the spinner landing on green:

To predict the probability of the spinner landing on green, you need to know the total number of possible outcomes and the number of favorable outcomes (landing on green). Let's assume there are "x" favorable outcomes for green.

Probability of landing on green = (Number of favorable outcomes) / (Total number of outcomes)

Since the spinner is spun 150 times, the total number of outcomes is 150. The probability will be:

Probability of landing on green = x / 150

2. Proportional relationship between regular price and sale price:

The fabric store is having a sale, and every item's price is reduced by 30%. To find the proportional relationship between the regular price (r) and the sale price (s), we can use the following equation:

Sale price (s) = Regular price (r) * (1 - Discount percentage)

Since the discount percentage is 30%, we can write the equation as:

s = r * (1 - 0.30)

or

s = 0.70r

This equation shows the proportional relationship between the regular price (r) and the sale price (s).

The measure of angle 5 of the transverse lines is; C.) 105°

The line transversal theorem states that If two parallel lines are cut by a transversal, then it means that corresponding angles are congruent. Two lines cut by a transversal are parallel IF AND ONLY IF corresponding angles are congruent.

Now, we are given that the measure of 2 is 75°. It is clearly seen that angle 5 is a corresponding angle to angle 1 and angle 1 forms a straight line with angle 2. Sum of angles on a straight line is 180 degrees. Thus;

angle 5 = 180 - 75

angle 5 = 105°

Answer:

Pizza 1: lenght(l)=16 and width(w)=4

Perimeter=40in.

Pizza 2: l=32 and w=2

Perimeter=68in.

Step-by-step explanation:

1. List down factors of 64.

64=1,2,4,8,16,32,64

2. Select the factors you'll be using to draw your rectangles. In this case I selected the factors 2,4,16 and 32 because area of rectangle=l×w. Therefore 2×32=64 and 4×16=64.

3. Draw your rectangles according to the measurements you chose. If the drawing is too big to fit the box you can simply use a scale. Such as 1 inch=4 inches on your drawing. For example, when drawing the length of the second Pizza which is 32in. you can simply draw a line of 8 inches.

4. After drawing your pizzas you niw have to find the Perimeter of both. Simply use the formula Perimeter of a rectangle=2(l+w)

Pizza 1: Perimeter=2(16+4)

=2×20

=40in.

Now do the same for Pizza 2 using its own lengjt and width. Hope this helped.

The probability the chosen volunteer does not possess yq 77 is 0.655 (nearest to three decimal places).

Given information: One of the volunteers whose sam 77 test result was positive will be chosen at random.

To find: The probability the chosen volunteer does not possess yq 77.

Let P(Y) be the probability that a volunteer possesses yq77 and P(Y') be the probability that a volunteer does not possess yq77. It is given that out of 150 volunteers, 77 tested positive for SAM.

Therefore, the probability of testing positive for SAM is:

P(SAM) = number of volunteers who tested positive for SAM / total number of volunteers= 77/150

Now, using the probability law of total probability, we can find the probability of a volunteer not possessing yq77, as follows:

P(Y') = P(Y'|SAM) P(SAM) + P(Y'|SAM') P(SAM')

It is given that yq77 is found in 60% of volunteers who tested positive for SAM, and in 30% of those who did not test positive for SAM.

Therefore:

P(Y'|SAM) = 0.6, P(Y'|SAM') = 0.3

Now, substituting the given values in the equation,

P(Y') = (0.6 × 77/150) + (0.3 × 73/150)≈ 0.655

Lengths of the diagonals are decreasing at a rate of approximately 7.07 meters per second when the sides are 5 meters long.

Area of the square is decreasing at a rate of 10 square meters per second when the sides are 5 meters long.

a) To find the rate of change of the area of the square, we can use the formula A = s², where A is the area and s is the length of the side. We can take the derivative of both sides with respect to time to get dA/dt = 2s(ds/dt).

Puting in the values given, we get dA/dt = 2(5)(-1) = -10 m²/s. Therefore, the area of the square is decreasing at a rate of 10 square meters per second when the sides are 5 meters long.

b) To find the rate of change of the lengths of the diagonals, we can use the Pythagorean theorem. Let d be the length of the diagonal, then d² = s² + s² = 2s². Taking the derivative of both sides with respect to time, we get

2d(dd/dt) = 4s(ds/dt).

Puting in the values given, we have 2d(dd/dt) = 4(5)(-1), which simplifies to dd/dt = -10/sqrt(2) m/s.

Therefore, the lengths of the diagonals are decreasing at a rate of approximately 7.07 meters per second when the sides are 5 meters long.

Step-by-step explanation:

The correct answer is A. The null hypothesis is rejected in error.

In statistical hypothesis testing, a Type II error occurs when the null hypothesis is incorrectly retained or failed to be rejected when it is actually false.

In other words, a Type II error happens when the researcher concludes that there is no significant difference or relationship between variables when, in reality, there is.

It is a false negative result, as the researcher fails to detect a true effect or relationship.

Option A accurately describes Type II error, while the other options are not related to Type II error.

Option B refers to rejecting the research hypothesis, which is not a Type II error but rather a Type I error.

Option C refers to the study being underpowered, which may increase the likelihood of both Type I and Type II errors but is not a direct description of Type II error.

Option D mentions double-blinding, which is a methodological consideration and not directly related to Type II error.

Option E refers to accepting the research hypothesis in error, which is not a Type II error but rather a correct decision or Type I error.

Answer: Find the vertex form of h(x) = x2 - 14x + 6?

Solution:

It is given that,

h(x) = x2 - 14x + 6

We know that the vertex form is obtained by completing the square.

So we have to add and subtract a term, which is formed by the squared power of half the coefficient of the linear term:

= x2 - 14x + 6

= x2 - 14x + 6 + (14/2)2 - (14/2)2

= x2 - 14x + 6 + 72 - 72

= x2 - 14x + 72 + 6 - 72

Use the algebraic identity,

(a - b)2 = a2 - 2ab + b2

= (x - 7)2 + 6 - 72

= (x - 7)2 + 6 - 49

= (x - 7)2 - 43

Therefore, the vertex form of h(x) = x2 - 14x + 6 is (x - 7)2 - 43.

Find the vertex form of h(x) = x2 - 14x + 6?

Fruit punch is served during the reception in 154-ounce cups using division.

Repetitive subtraction is the process of division. It is the multiplication operation's opposite. It is described as the process of creating equitable groupings. When dividing numbers, we divide a bigger number down into smaller ones such that the larger number obtained will be equal to the multiplication of the smaller numbers.

For instance, 4 2 Equals 2. As a multiplication fact, this can be expressed as 2 + 2 = 4.

The division is represented mathematically by a symbol consisting of a tiny horizontal line with dots above and below the line. The division of two integers is represented by one of two fundamental division symbols.

Total fruit punch foe prepared = 3696 ounces

Number of punch balls = 4

Each serving has = 6 ounces of punch

So, 4 servings will have

4 × 6 = 24
