True, if Στ = 0 in a single-factor experiment, then all treatment means must be equal.

In single-factor experiments, if the sum of the treatment effects (Στ) is equal to zero (Στ = 0) for all levels (i=1 to n), then it implies that all treatment means (Ti) must be equal.

In a single-factor experiment, a single independent variable (factor) is manipulated, and its effect on the dependent variable is studied across different levels or treatments.

The treatment effects (τ) represent the differences in the mean response between each treatment level and the overall mean of the dependent variable.

If the sum of these treatment effects (Στ) is equal to zero (Στ = 0), it means that the positive and negative differences cancel each other out, resulting in a net effect of zero.

If Στ = 0, it implies that the total treatment effect across all levels is balanced, indicating that there are no systematic differences between the treatment means.

Consequently, if all treatment effects cancel out and Στ = 0, it implies that the means of all treatment levels (Ti) must be equal since any deviations from the overall mean are offset by equal and opposite deviations in other treatment levels.

Therefore, if Στ = 0 in a single-factor experiment, it indicates that all treatment means must be equal.

Given that the test's p-value is 0.0562>0.05, there is enough data to conclude that the machines' manufacturer should perform a new calibration.

A statistic employed in statistical hypothesis testing is known as a test statistic. A test statistic, which can be thought of as a numerical summary of a data set that condenses the data into a single value that can be used to conduct the hypothesis test, is how a hypothesis test is commonly expressed.

Here,

x=4.88 cm

μ=5 cm

σ=0.44 cm

n=49

The test statistic,

=(4.88-5)/(0.44/7)

z=-1.909

The p-value of the test is the probability that the sample mean is different by at least 4.88 - 5 = 0.12 from the target value, which is P(|z| > -1.909), which is 2 multiplied by the p-value of z = -1.909

At z=-1.909, p-value=0.0281

2*0.0281=0.0562

The test's p-value is 0.0562>0.05, indicating that there is enough data to conclude that the machines' manufacturer should perform a recalibration.

The equation 5(2x – 3) = 5  has one solution.

The solution of the equation is x = 2.

Equations are mathematical statements containing two algebraic expressions on both sides of an 'equal to (=)' sign.

Therefore, let's solve the equation as follows:

5(2x – 3) = 5

open the brackets

5(2x – 3) = 5

10x - 15 = 5

add 15 to both sides of the equation

10x - 15 = 5

10x - 15 + 15 = 5 + 15

10x  = 20

divide both sides by 10

x = 20 / 10

x = 2

Hence, the solution of the equation is x = 2.

The total interest that will be paid over the life is $5,28,000. The solution has been obtained using arithmetic operations.

What are arithmetic operations?

For all the real numbers, there are four basic mathematical operations which are:

1. Addition(‘+’) wherein the sum of the numbers is obtained.

2. Subtraction(‘-’) wherein the difference of the numbers is obtained.

3. Multiplication(‘×’) wherein the product of the numbers is obtained.

4. Division(‘÷’) wherein the quotient of the numbers is obtained.

We are given 30 year loan amounting $220,000 at interest rate of 8 percent with monthly payments of $1,614.28.

The range of the function g(x) = |x - 12| - 2 is {y | y > -2}, indicating that the function can take any value greater than -2.

To find the range of the function g(x) = |x - 12| - 2, we need to determine the set of all possible values that the function can take.

The absolute value function |x - 12| represents the distance between x and 12 on the number line. Since the absolute value always results in a non-negative value, the expression |x - 12| will always be greater than or equal to 0.

By subtracting 2 from |x - 12|, we shift the entire range downward by 2 units. This means that the minimum value of g(x) will be -2.

Therefore, the range of g(x) can be written as {y | y > -2}, which means that the function can take any value greater than -2. In other words, the range includes all real numbers greater than -2.

Visually, if we were to plot the graph of g(x), it would be a V-shaped graph with the vertex at (12, -2) and the arms extending upward infinitely. The function will never be less than -2 since we are subtracting 2 from the absolute value.

The sum of interior Angles of Hexagon is always 720°

Any hexagon's internal angles add up to 720° in all cases. By dividing 720° by 6, we may get the size of each interior angle of a regular hexagon. As a result, we have:

720°÷6 = 120°

In a regular hexagon, each inside angle is 120°.

An example of a regular hexagon with equal-length sides and angles is shown in the diagram below. By multiplying the six 120° angles together, we can demonstrate that the result is 720°.

Therefore, the interior angles of a hexagon are always added up to 720°.

\(2x = 56.3\)

\(x = 28.15\)

b.

\((3 \cos(x) + 1)(2 \cos(x) + 3) = - 2\)

\(6 \cos {}^{2} (x) + 11 \cos(x) + 3 = - 2\)

\(6 \cos {}^{2} (x) + 11 \cos(x) + 5 = 0\)

\(6 \cos {}^{2} (x) + 6 \cos(x) + 5 \cos(x) + 5 = 0\)

\(6 \cos(x) ( \cos(x) + 1) + 5( \cos(x) + 1) = 0\)

\((6 \cos(x) + 5)( \cos(x) + 1) = 0\)

Set each factor equal to zero.

\(6 \cos(x) + 5 = 0\)

\(6 \cos(x) = - 5\)

\( \cos(x) = - \frac{5}{6} \)

\(x = \cos {}^{ - 1} ( \frac{5}{6} ) \)

Step-by-step explanation:

American nickels are issued as currency. A value of $1.70 is equal to 10 nickels and 12 dimes ($0.50 + $1.20).

A dime is worth ten cents and a nickel five cents. In other words, one dime is equivalent to two nickels.

In light of this, we might state that a nickel is worth half what a dime is worth.

Despite having a higher value than a nickel, the dime is smaller.

n + d = 22 <— d = 22-n

Amount in pennies: 5n + 10d = 170

5n + 10(22 - n) = 170

5n + 220 - 10n = 170

220 - 5n = 170

220 - 170 - 5n = 0

50 - 5n = 0

50 = 5n

n = 10

A value of $1.70 is equal to 10 nickels and 12 dimes ($0.50 + $1.20).

So, -7π/9, -19π/9, and -31π/9 are three negative angles coterminal with 5π/9.

To find angles coterminal with 5π/9, we need to add or subtract a multiple of 2π until we reach another angle with the same terminal side.

To find a positive coterminal angle, we can add 2π (one full revolution) repeatedly until we get an angle between 0 and 2π:

5π/9 + 2π = 19π/9

19π/9 - 2π = 11π/9

11π/9 - 2π = 3π/9 = π/3

So, 19π/9, 11π/9, and π/3 are three positive angles coterminal with 5π/9.

To find a negative coterminal angle, we can subtract 2π (one full revolution) repeatedly until we get an angle between -2π and 0:

5π/9 - 2π = -7π/9

-7π/9 - 2π = -19π/9

-19π/9 - 2π = -31π/9

For the angle J in this problem, we have that:

Hence the cosine of angle J is given as follows:

\(\cos{J} = \frac{4}{\sqrt{98}} \times \frac{\sqrt{98}}{\sqrt{98}}\)

\(\cos{J} = \frac{4\sqrt{98}}{98}\)

\(\cos{J} = \frac{2\sqrt{98}}{49}\)

The measure of an exterior angle of a triangle is equal to the measure of its neighboring interior angle if both measure 90 degrees, according to the theory of supplementary angles.

If the sums of two angles equal 180 degrees, they are said to be supplementary.

However, two angles do not need to be near one another in order to be complementary.

If two angles' measures sum up to 180 degrees, they are said to be supplementary.

A triangle's outside angle complements the neighboring inner angle.

The adjacent internal angle will therefore likewise be 90 degrees if the exterior angle is.

Answer:

The equation of line in point slope form is: \(\mathbf{y+5=-\frac{2}{3} (x-4)}\)

Option A is correct option.

Step-by-step explanation:

We need to identify an equation in point-slope form the line parallel to y=-2/3x+8 that passes through(4, -5).

The general equation of point slope form is: \(y-y_1=m(x-x_1)\)

where m is slope of the equation.

Finding slope of the equation.

Since the two lines are parallel so, both lines have same slope.

Equation of given line: y=-2/3x + 8

This equation is in slope-intercept form, comparing with general equation \(y=mx+b\) where m is slope , we get the value of m= -2/3

So, slope of given line = m = -2/3

Slope of required line = m =-2/3

Now, writing equation in point-slope form:

We are given point (4,-5) so, we have \(x_1=4, y_1=-5\) and slope is: m=-2/3

So, equation of line in point-slope form is:

\(y-y_1=m(x-x_1)\\y-(-5)=-\frac{2}{3}(x-4)\\y+5=-\frac{2}{3}(x-4)\)

So, the equation of line in point slope form is: \(\mathbf{y+5=-\frac{2}{3} (x-4)}\)

Option A is correct option.
