Did the test

Answer: The critical value is a value used in hypothesis testing to determine the rejection or acceptance of a null hypothesis. The critical value is determined based on the significance level of the test and the degrees of freedom. The critical value is usually determined from a table or calculated using statistical software.

Here are the general steps to calculate the critical value:

Determine the significance level, denoted by α. This is the probability of making a Type I error, which is the probability of rejecting a true null hypothesis.

Determine the degrees of freedom, which depend on the specific test and sample size.

Look up the critical value in a table of critical values for the appropriate significance level and degrees of freedom. These tables are available in most statistics textbooks or can be found online.

If a table is not available, the critical value can be calculated using statistical software or a calculator that provides a cumulative distribution function for the appropriate distribution. For example, the critical value for a two-tailed t-test can be calculated in R using the qt function. The syntax is qt(1-α/2, df), where α is the significance level and df is the degrees of freedom.

Note that the critical value will depend on the specific hypothesis test being performed and the null and alternative hypotheses. It is important to choose the correct test and use the appropriate critical value to ensure accurate results.

Answer:

B

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 2x + 3 ← is in slope- intercept form

with slope m = 2

Parallel lines have equal slopes, thus

y = 2x + c ← is the partial equation

To find c substitute (3, 1) into the partial equation

1 = 6 + c ⇒ c = 1 - 6 = - 6

y = 2x - 5 → B

The number of compounding years that

Tim and Sally should request when they are taking out a personal loan to pay

is 4 years.

A loan is an amount taken that's to be returned at a specific period.

To calculate the number of years goes thus:

P = PMT × (1 - 1/(1 + r)^n /r(

where P = 9000

interest = 9.5% = 0.095

This will be:

9000 = 250 × [(1 - 1/1 + 0.00791)^n / 0.007917)

Solving for n will be 48 months

Since 12 months = 1 year

48 months = 48/12 = 4 years.

The number of years is 4 years.

Step-by-step explanation:

5 (x + 6) = 45

Multiply 5 by what's in parenthesis.

5 times x = 5x ** use the + sign ** 5 times 6 = 30

5x + 30 = 45

The equation that is equivalent to  5x + 30 = 45 is 5(x + 6) = 45.

The option that would be equivalent to the value of x in the equation. The first step is to determine the value of x.

5x + 30 = 45

Combine similar terms

5x = 45 - 30

5x = 15

Divide both sides by 5

x = 3

Option A

35x = 45

In order to determine the value of x, divide both sides by 35

x = 45 / 35  = 1.3

Option B

5x = 75

In order to determine the value of x, divide both sides by 5

x = 75/5 = 15

Option C

5(x + 30) = 45

Divide both sides of the equation by 5

x + 30 = 9

Combine similar terms

x = - 30 + 9

x = -21

Option D

5(x + 6) = 45

Divide both sides of the equation by 5

x + 6 = 45 / 5

x + 6 = 9

Combine similar terms

x = 9 - 6

x = 3

The system equations are y= -1.3x+130 and  y =\(\frac{-167}{5625}x^2+167\).

What is equation?

When the slope of the line being studied is known, and the provided point is also the y intercept, the slope intercept formula, y = mx + b, is utilised (0, b).   It provides both a slope and an intercept, which is why the form is known as the slope-intercept form.

Here let us set the origin as (0,0) in lower left.

Then slope m = -130/100 = -1.3

Y-intercept  b= 130 ft.

Then equation is y=mx+b

=> y= -1.3x+130

Now for the parabola , it appears that the vertex is at 167 ft.

V=(0,167)

Now using vertex form of equation then,

=> y = a\((x-p)^2+q\)

=> y = a\(x^2\)+167

Now y=0 when x=75 then,

=> 0 = a\(75^2\)+167

=> -167=5625a

=> a = -167/5625

Then the equation is y =\(\frac{-167}{5625}x^2+167\).

Rounding to one decimal place, the initial population p0 is approximately 4954 by using integration in given equation
dp/dt = kp

1. First, let's establish the proportionality relationship. If the population growth rate is proportional to the number of people present at time t, we can write the equation as:

dp/dt = kp, where dp/dt is the population growth rate, k is the constant of proportionality, and p is the population at time t.

2. We need to solve this differential equation to find the relationship between the population p and the time t. Separating variables and integrating, we get:

∫(1/p) dp = ∫k dt

=> ln(p) = kt + C, where C is the integration constant.

3. To find C, we'll use the information that the population doubles in 5 years:

ln(2p0) = k(5) + ln(p0)

=> ln(2) = 5k

=> k = ln(2)/5

4. Now we know that the population is 8,000 after 3 years. We can plug this information into the equation:

ln(8000) = (ln(2)/5)(3) + ln(p0)

5. Solving for p0:

ln(p0) = ln(8000) - (ln(2)/5)(3)

=> p0 = e^(ln(8000) - (ln(2)/5)(3))

=> p0 ≈ 4954.3

The values of a and b that make the piecewise defined function f(x) = 3x + 4, for x < -3, and f(x) = 2x^2 + ax + b, for x > -3, both continuous and differentiable everywhere are a = 6 and b = 9.

To ensure that the piecewise defined function is continuous at the point where x = -3, we need the left-hand limit and right-hand limit to be equal. The left-hand limit is given by the expression 3x + 4 as x approaches -3, which evaluates to 3(-3) + 4 = -5.

On the right-hand side of the function, when x > -3, we have the expression 2x^2 + ax + b. To find the value of a, we need the derivative of this expression to be continuous at x = -3. Taking the derivative, we get 4x + a. Evaluating it at x = -3, we have 4(-3) + a = -12 + a. To make this expression continuous, a must be equal to 6.

Next, we find the value of b by considering the right-hand limit of the piecewise function as x approaches -3. Substituting x = -3 into the expression 2x^2 + ax + b, we get 2(-3)^2 + 6(-3) + b = 18 - 18 + b = b. To make the function continuous, b must equal 9.

Therefore, the values of a and b that make the piecewise defined function both continuous and differentiable everywhere are a = 6 and b = 9.
