Answer:

1) 5/6
2) 19/30
3) They are mutually exclusive.

Step-by-step explanation:

Let's break the diagram down.
We have four types of smoothies:

Contains apple but not blueberry - 12
Contains blueberry but not apple - 7
Contains both blueberry and apple - 3
Doesn't contain either - 8

From here, we find that there are 30 smoothies in total.

In addition, we know that the number of smoothies containing an apple is 15, and the number of smoothies containing blueberry is 10.

Therefore,

[tex]P(\text{contains apple}) = \frac{\text{contains apple}}{\text{total}} = \frac{15}{30} = \frac12\\\\P(\text{contains blueberry}) = \frac{\text{contains blueberry}}{\text{total}} = \frac{10}{30} = \frac13\\\\\text{a) } P(\text{contains apple}) + P(\text{contains blueberry}) = \frac12 + \frac13 = \frac36 + \frac26 = \frac56[/tex]

Now, the probability of getting apple OR strawberry is given by adding the probabilities of getting one of the flavors but not the other.

[tex]P(\text{apple, no blueberry}) = \frac{12}{30}\\\\P(\text{blueberry, no apple}) = \frac{7}{30}\\\\P(\text{apple or blueberry}) = \frac{12}{30} + \frac7{30} = \frac{19}{30}[/tex]

We can check if the events are mutually exclusive using the formula:

[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B)[/tex]
In our case, A means contains apple, and B means contains blueberry.
[tex]P(A \cup B)[/tex] resembles the case for exclusively apple or exclusively blueberry (AKA our answer for b).

[tex]P(A \cap B)[/tex] resembles the case for both apple and blueberry (AKA the intersection), which is equal to 3/30 = 1/10.

If the two sides are equal, the cases are not mutually exclusive.

[tex]\frac{19}{30} = \frac{15}{30} + \frac{10}{30} - \frac{3}{30}\\\\\frac{19}{30} \ne \frac{22}{30}[/tex]

The solution of the equation for B over the interval [0,2π] is undefined

From the question, we have the following parameters that can be used in our computation:

-√3tan(β) = tan(β)sin(β)

Divide both sides of the equation by tan(β)

so, we have the following representation

-√3 = sin(β)

Rewrite as

sin(β) = -√3

Take the arc sin of both sides

β = undefined

Hence, the solution of the equation for B over the interval [0,2π] is undefined

A graph of this quadratic equation x² + x - 6 = 0 is shown below.

The solutions to the equation x² + x - 6 = 0 are (-3, 0) and (2, 0).

In Mathematics, the graph of a quadratic function always form a parabolic curve or arc because it is u-shaped. Based on the graph of this quadratic function, we can logically deduce that the graph is an upward parabola because the coefficient of x² is positive one (1) and the value of "a" is greater than zero (0).

Since the leading coefficient (value of a) in the given quadratic function x² + x - 6 = 0 is positive one (1), we can logically deduce that the parabola would open upward and the solution would be on the x-intercepts (-3, 0) and (2, 0).

Reema should use 3 hooks. The distance between the hooks is approximately 4 inches, and the distances of each hook from the left edge of the wood are approximately 1.75 inches, 5.75 inches, and 9.75 inches.

Given:

Wall length: 4 feet

Wood length: 28 inches

Space between hooks: about 7 or 8 inches

Minimum distance from each end: 1 3/4 inches

To center the coat rack on the wall, we need to find the remaining space on either side of the wood after accounting for the minimum distances from each end.

Convert measurements to inches:

Wall length: 4 feet = 48 inches

Calculate the available space for the wood on the wall:

Available space on each side = (Wall length - Wood length) / 2

Available space on each side = (48 inches - 28 inches) / 2

Available space on each side = 20 inches / 2

Available space on each side = 10 inches

Determine the number of hooks and the space between them:

Space between hooks: about 7 or 8 inches

Let's assume we choose a space of 8 inches between hooks for this calculation.

Remaining space for hooks = Wood length - (Minimum distance from each end × 2)

Remaining space for hooks = 28 inches - (1 3/4 inches × 2)

Remaining space for hooks = 28 inches - (3 1/2 inches)

Remaining space for hooks = 28 inches - 7/2 inches

Remaining space for hooks = 28 inches - 3.5 inches

Remaining space for hooks = 24.5 inches

Number of hooks = Remaining space for hooks / Space between hooks

Number of hooks = 24.5 inches / 8 inches (approximately)

Number of hooks ≈ 3.06 (rounded to the nearest whole number)

Since we cannot have a fraction of a hook, we'll round down to 3 hooks.

Calculate the distance between hooks:

Distance between hooks = Space between hooks / (Number of hooks - 1)

Distance between hooks = 8 inches / (3 hooks - 1)

Distance between hooks = 8 inches / 2

Distance between hooks = 4 inches

Calculate the distance of each hook from the left edge of the wood:

Hook 1 distance from the left edge = Minimum distance from each end

Hook 2 distance from the left edge = Minimum distance from each end + Distance between hooks

Hook 3 distance from the left edge = Minimum distance from each end + (Distance between hooks × 2)

Using the given minimum distance from each end of 1 3/4 inches (or 1.75 inches), we can calculate the distances for each hook:

Hook 1 distance from the left edge = 1.75 inches

Hook 2 distance from the left edge = 1.75 inches + 4 inches

Hook 2 distance from the left edge = 5.75 inches

Hook 3 distance from the left edge = 1.75 inches + (4 inches × 2)

Hook 3 distance from the left edge = 9.75 inches

So, Reema should use 3 hooks. The distance between the hooks is approximately 4 inches, and the distances of each hook from the left edge of the wood are approximately 1.75 inches, 5.75 inches, and 9.75 inches.

Step-by-step explanation:

Based on the regression equation, the best prediction for the price of a 70-pound container of detergent can be found by substituting x = 70 into the equation:

y^ = 0.86x + 0.52

y^ = 0.86(70) + 0.52

y^ = 60.2 + 0.52

y^ ≈ $60.72

Therefore, the best prediction for the price of a 70-pound container of detergent is approximately $60.72. However, since we are dealing with prices, it is reasonable to round this value to the nearest dollar, which would be $61. But since none of the answers are 61 it would be $60.

The job A is the best job based on pay scale

Given data ,

a) Job A:

Hours per week: 40

Hourly rate: $15

On simplifying the equation , we get

Gross pay per week: 40 hours * $15/hour = $600

b) Job B:

Hours per week: 30

Hourly rate: $5

On simplifying the equation , we get

Gross pay per week: 30 hours * $5/hour = $150

In addition to the base pay, Job B also offers tips averaging $350 per week.

Considering the total compensation for each job:

Total compensation for Job A: $600 per week (base pay)

Total compensation for Job B: $150 per week (base pay) + $350 per week (tips) = $500 per week

Based on the total compensation, Job A offers a higher gross pay of $600 per week, while Job B offers a total compensation of $500 per week.

Hence , if the decision is solely based on pay, Job A would be the better choice.

Answer:

The length of a side of the base of the box is 13 cm.

Step-by-step explanation:

To find the length of a side of the base of the box, we need to use the formula for the volume of a box.

The volume of a box is given by the formula:

V = l^2 * h

Where:

V is the volume,

l is the length of a side of the base, and

h is the height of the box.

Substituting the given values:

V = 1352 cm^3

h = 8 cm

1352 = l^2 * 8

Dividing both sides by 8:

l^2 = 169

Taking the square root of both sides:

l = √169

Calculating the length of a side of the base:

l = 13 cm

Therefore, the length of a side of the base of the box is 13 cm.

In my community, there are several situations where hypothesis testing can be applied. Here are three examples: Traffic Flow Optimization, Recycling Program Assessment, and Crime Prevention Strategy Evaluation

For the purpose of this response, let's choose Situation 1 (Traffic Flow Optimization) and go through the four steps.

1. Problem Statement: The local authorities want to determine if implementing a new traffic signal timing system will significantly reduce the average travel time for commuters passing through a busy intersection during peak hours.

2. Null Hypothesis (H0): The new traffic signal timing system has no effect on the average travel time for commuters passing through the intersection.

Alternative Hypothesis (H1): The new traffic signal timing system significantly reduces the average travel time for commuters passing through the intersection.

3. Level of Significance: α = 0.05

4. Rejection Region: The rejection region will depend on the specific test statistic used. Let's assume we are using a t-test to compare the mean travel time before and after implementing the new traffic signal timing system. In this case, we would calculate the t-statistic and determine the critical value(s) based on the degrees of freedom and the chosen level of significance. The rejection region would be in the tails of the t-distribution corresponding to the critical value(s).

Possible Type I Error: Rejecting the null hypothesis when it is actually true, indicating that the new traffic signal timing system is effective when it is not. In this case, it would mean concluding that the new system significantly reduces travel time when, in reality, it has no effect.

Possible Type II Error: Failing to reject the null hypothesis when it is actually false, indicating that the new traffic signal timing system is ineffective when it is actually effective. In this case, it would mean not detecting a significant reduction in travel time when the new system does indeed have a positive impact.

It's worthy of note that the specific test statistic and rejection region may vary depending on the nature of the data and the chosen statistical test. The above steps provide a general framework for conducting hypothesis testing in the given situation.
