A hypothesis test using a significance level of
= 0.05
produces a P-value of 0.066.
Which of the following conclusions is appropriate?
Accept the null (WHICH WE NEVER DO!) hypothesis at = 0.05 level.
Do not reject the null hypothesis at = 0.05 level.
Reject the null hypothesis at = 0.05 level.
Reject the alternative hypothesis at = 0.05 level.

Answers

Answer 1

Answer:

Do not reject the null hypothesis at = 0.05 level.

Step-by-step explanation:

There's a saying like " If P is low, H.o must go" or "if P is low, reject the H.o".

H.o is another way of saying null hypothesis.

In our situation, our p values is actually bigger than the significance level thus we cannot reject the H0. We can never accept accept null. Thus the only thing we can say is "Do not reject the null hypothesis at = 0.05 level". We also say "Fail to reject the null".

I don't know about what you were taught but for me, we were taught to usually not bring alternative hypothesis in discussion b/c the point of the whole study is to disprove or find contrary information to null hypothesis thus we either reject null or fail to reject it (nothing to do with alternate)

1. A student says that the zeros of y = (x - 2)(x + 7) are -2 and 7. Is the student correct? If not, describe and correct the error the student made.

2. Explain why x^2 + 25 is not equal to (x + 5)^2?

3. Describe how the factoring can help you find the x-intercepts of the graph of the quadratic function y = x^2 - 4x + 3.

Answers

Answer: 1) NO. the zeros are: 2 and -7

              2) (x + 5)² has a middle term when in expanded form

             3) Factoring provides the Intercept form: y = a(x - p)(x - q)

Step-by-step explanation:

1) y = (x - 2)(x + 7)

To find the zeros, set the factors equal to zero:

0 = x - 2        0 = x + 7

x = 2              x = -7

The zeros are 2 and -7.  

The student did not set the factors equal to zero.

2) (x + 5)² = (x + 5)(x + 5)

               = x² + 5x + 5x + 25

               = x² + 10x + 25       ≠  x² + 25

3) The Intercept form of a quadratic equation is: y = a(x - p)(x - q) where p and q are the x-intercepts.  Notice that the intercept form IS the factored form. Set the factors equal to zero to find the x-intercepts.

y = x² - 4x + 3

y = (x - 1)(x - 3)     --> Intercept form

0 = (x - 1)(x - 3)    --> finding the zeros (aka x-intercepts)

0 = x - 1       0 = x - 3

x = 1            x = 3       -->    zeros are 1 and 3

1.The zeroes are 2,-7

2.\(x^2 + 25\neq ( x + 5)^{2}\)

3. So, factoring can help to find the x-intercepts

1.We have y = (x - 2)(x + 7)

For zeroes of y , Put y=0

(x - 2)(x + 7) =0

x=2,-7

So, the zeroes of y = (x - 2)(x + 7) are 2 and -7.

2. We have \(x^2 + 25\)

\(x^2 + 25= x^2 + 5^{2}\)

And

\((x+ 5)^{2} \\=x^{2} +5^{2} +10x\\=x^{2} +25 +10x\\\neq x^{2} +25\)

So, \(x^2 + 25\neq ( x + 5)^{2}\)

3.We have the quadratic function \(y = x^2 - 4x + 3\)

\(y=x^2 - 4x + 3\\=(x-3)(x-1)\\\)

For x-intercept put y=0, we get

\((x-3)(x-1)=0\\x=3,x=1\)

So, factoring can help to find the x-intercepts of the graph of the quadratic function \(y = x^2 - 4x + 3.\)

The volume of a cone is 13.4m cubed and the radius is 3.2m what is the height

Answers

Answer:

The height is 1.25m.

Step-by-step explanation:

Volume = 1/3 πr²h

Given:

V = 13.4 m³

r = 3.2 m

Asked: height (h)

Substitute the formula with the given values then solve

13.4m³ = 1/3π(3.2m)²h

13.4(3) = 10.24πh

40.2 = 10.24πh

h = 40.2/10.24π

h = 1.25m

The height of the cone is 1.25 meters.

We know that the volume of the cone is given by

V = (1 / 3) * π * r ^2 * h................equation 1

where,

V is the volume of the cone.

r is the radius of the cone's base

h is the height

The volume and radius of the cone are given,

V = 13.4 m

r = 3.2m

substituting these values in equation 1 we get,

13.4 = (1 / 3) * 3.14 * 3.2 ^ 2 * h

on simplifying further

13.4 = 10.717  * h

h = 1.25m

The height of the cone is 1.25 meters.

Answers

Both parabolic equations yield distinct y values for any x in the set of integers (Z). Thus, there are two distinct y values satisfying the given equation.

How to solve

There are two distinct y values satisfying the given equation.

First, we rewrite the equation as |y-3| = 5 - x² + 8x - 18. Then, we express |y-3| as two cases: y-3 and -(y-3).

Case 1: y - 3 = 5 - x² + 8x - 18

Solving for y, we get y = x² - 8x + 16.

Case 2: -(y - 3) = 5 - x² + 8x - 18

Solving for y, we get y = x² - 8x + 10.

Camila has 6 bags of candy. She can pour 1/3 of a bag of candy into a bowl. How many bowls of candy can Camila make in all?

Answers

Answer:

18 Bowls of Candy

Step-by-step explanation:

Camila has 6 bags of candy, and she can pour 1/3 of a bag into a bowl. To determine how many bowls of candy she can make in total, we need to divide the total amount of candy by the amount of candy per bowl.

Since Camila can pour 1/3 of a bag into a bowl, it means she can make 3 bowls of candy with a full bag.

Now, we can calculate the total number of bowls of candy:

Total bowls of candy = (Number of bags) x (Bowls per bag)

Total bowls of candy = 6 bags x 3 bowls per bag

Total bowls of candy = 18 bowls

Therefore, Camila can make a total of 18 bowls of candy with her 6 bags of candy.

Please only responded if you know how to do it, will give the brainiest to however answers it correctly

Answers

The total value of the loan with quarterly compounded interest is approximately $45,288.38, while the total value of the loan with monthly compounded interest is approximately $45,634.84. The difference in total interest accrued is approximately $346.46.

Part A: To determine the total value of the loan with quarterly compounded interest, we can use the formula for compound interest:

A = P(1 + r/n)^(nt),

where:

A is the total value of the loan,

P is the principal amount (initial loan amount),

r is the interest rate (in decimal form),

n is the number of times interest is compounded per year,

and t is the number of years.

Given:

P = $20,000,

r = 9% or 0.09,

n = 4 (quarterly compounding),

t = 10 years.

Substituting the values into the formula, we have:

A = 20000(1 + 0.09/4)^(4*10).

Calculating this value, we find:

A ≈ $45,288.38.

Therefore, the total value of the loan with quarterly compounded interest is approximately $45,288.38.

Part B: To determine the total value of the loan with monthly compounded interest, we follow the same formula but with a different value for n:

n = 12 (monthly compounding).

Substituting the values into the formula, we have:

A = 20000(1 + 0.09/12)^(12*10).

Calculating this value, we find:

A ≈ $45,634.84.

Therefore, the total value of the loan with monthly compounded interest is approximately $45,634.84.

Part C: The difference between the total interest accrued on each loan can be calculated by subtracting the principal amount from the total value of each loan.

For the loan with quarterly compounding:

Total interest = Total value - Principal

Total interest = $45,288.38 - $20,000

Total interest ≈ $25,288.38.

For the loan with monthly compounding:

Total interest = Total value - Principal

Total interest = $45,634.84 - $20,000

Total interest ≈ $25,634.84.

The difference between the total interest accrued on each loan is approximately $346.46.

The property you are referring to is called the associative property of multiplication. According to this property, when multiplying three numbers, the grouping of the numbers does not affect the result. In other words, you can change the grouping of the factors without changing the product.

In the equation you provided: 3x(5x7) = (3x5)7

The associative property allows us to group the factors in different ways without changing the result. So, whether we multiply 5 and 7 first, or multiply 3 and 5 first, the final product will be the same.

Therefore the value of x is less than 4 when x is in the inequality 3x + 2 < 14 and greater than -3 when x is in the inequality 2 x-5> -11

What is inequality?

In mathematics, "inequality" refers to a relationship between two expressions or values that is not equal to each other. Therefore, inequality emerges from a lack of balance. For instance, let's say you have 225 and want to purchase a new bicycle that costs $250.

What is expressions or values?

Expressions are carried out, or evaluated, in order to yield a value. In an evaluation process, values of expressions can be employed as components of surrounding expressions.

To solve for x in the inequality 3x + 2 < 14, we can begin by subtracting 2 from both sides to get 3x < 12. Then, dividing both sides by 3 gives x < 4.

To solve for x in the inequality 2 x-5> -11, we can begin by adding 5 to both sides to get 2x> -6, then divide both sides by 2 to get x > -3

So x can be any number greater than -3 and less than 4

Since the inequality is strict (y >), we draw a dashed line to indicate that points on the line are not solutions to the inequality. Then, we shade the region above the line to indicate all points that satisfy the inequality.

If we have (3,5) as a point, we can see that it lies on the boundary line

. Suppose a government agency has a monopoly in the provision of internet connections.
The marginal cost of providing internet connections is 1
2
, whereas the inverse demand
function is given by: p = 1

Answers

The government agency as a monopolist will produce and sell internet connections up to the point where the marginal cost is 1/2. The price will be set at 1, given the perfectly elastic demand function.

In the scenario where a government agency has a monopoly in the provision of internet connections and the inverse demand function is given by p = 1, we can analyze the market equilibrium and the implications for pricing and quantity.

The inverse demand function, p = 1, implies that the market demand for internet connections is perfectly elastic, meaning consumers are willing to purchase any quantity of internet connections at a price of 1. As a monopolist, the government agency has control over the supply of internet connections and can set the price to maximize its profits.

To determine the optimal pricing and quantity, the monopolist needs to consider the marginal cost of providing internet connections. In this case, the marginal cost is given as 1/2. The monopolist will aim to maximize its profits by equating marginal cost with marginal revenue.

Since the inverse demand function is p = 1, the revenue received by the monopolist for each unit sold is also 1. Therefore, the marginal revenue is also 1. The monopolist will produce up to the point where marginal cost equals marginal revenue, which in this case is 1/2.

As a result, the monopolist will produce and sell internet connections up to the quantity where the marginal cost is 1/2. The monopolist will set the price at 1 since consumers are willing to pay that price.
