Step-by-step explanation:

Yes, the equation y = 5x represents direct proportion.

In Mathematics, a proportional relationship produces equivalent ratios and it can be modeled or represented by the following mathematical equation:

y = kx

Where:

In order to have a proportional relationship, the variables representing the each of the quantities must have the same constant of proportionality:

Constant of proportionality, k = y/x

Constant of proportionality, k = 5/1

Constant of proportionality, k = 5.

In conclusion, we can logically deduce that the given equation represents direct proportion.

Equation: \(S = 40w + 550\)

Amount of money by the end of week 12: $1030

Step-by-step explanation:

Equation:

Total amount = (Amount of money per week) x ( Amount of weeks) + Starting amount

or

\(S = 40w + 550\)

-

You are solving for the total amount of money Heather will have in 12 weeks. Plug in 12 for w in the given equation, and solve for S with PEMDAS.

PEMDAS is the order of operations and stands for:

Parenthesis

Exponents (& Roots)

Multiplications

Divisions

Additions

Subtractions

~

\(s = 40w + 550\\w = 12\\\\s = 40(12) + 550\)

First, multiply 40 with 12:

\(s = (40 * 12) + 550\\s = (480) + 550\\s = 1030\)

$1030 will be the amount of money Heather will have in 12 weeks.

Jill's annual earnings can be calculated by multiplying her weekly pay by the number of weeks in a year: $298/week x 52 weeks/year = $15,496/year. Her earnings to date are $14,900, so she has earned an additional $596 in the current week.

Social Security is taxed at 6.2%, so the amount deducted from her pay each week is 6.2% of her gross weekly pay. That's 0.062 x $298 = $18.48.

The total surface area of the hemisphere is the sum of this curved surface area or the area of its base. The base of a hemisphere is circle of radius (r) equal as the radius of the sphere

Given,

hemisphere = 15

hight = 100

so, 100 - 15 = 85

a hemisphere is half of the sphere so to get a hemisphere from the sphere you divide by 2. the hight of the hemisphere is 15 feet so subtract that from the total of the 100 and you get 85.

The equation of the circle with center (0, 5) and a point on the circle (2, 4) is x² + (y - 5)² = 5

In geometry, a circle is a closed two-dimensional shape that is formed by a set of points that are equidistant from a fixed point called the center. The distance between any point on the circle and the center is called the radius.

The equation of a circle with center (h, k) and radius r is given by:

 r²=(x - h)² + (y - k)²  

In this case, the center of the circle is (0, 5) and a point on the circle is (2, 4). The radius of a circle, which is the separation between its centre and any point on the surface, may be calculated using the following formula:

r = √((2 - 0)² + (4 - 5)²) = √(5)

Now we can substitute the values of the center and the radius into the equation of the circle:

(x - 0)² + (y - 5)² = (√(5))²

Simplifying, we get:

x²+ (y - 5)² = 5

As a result, the circle's equation with its centre (0, 5) and a point on it (2, 4) is:

x² + (y - 5)² = 5

Answer:

The answer would be "j"

Step-by-step explanation:

First, you would want to find the value of the original equation:

5(y + 2) + 4

Use order of operations and distribute the five.

5y + 10 + 4

5y +14

This is the value of the original equation

Now we can work through the other options, but because we already know the answer, lets see about that one.

5 x y + 5 x 2 + 4

Again, use order of operations.

Multiply first

5y + 10 + 4

and complete the equation

5y + 14, which equals our original equation.

Answer:

sensory measurement are lower after hypnotism

Step-by-step explanation:

Given the data :

Before 6.6 6.5 9.0 10.3 11.3 8.1 6.3 11.6

After 6.8 2.4 7.4 8.5 8.1 6.1 3.4 2.0

The difference ;

After - Before, d = 0.2, - 4.1, - 1.6, - 1.8, - 3.2, - 2, - 2.9, - 9.6

Hypothesis :

H0 : μd = 0

H0 : μ < 0

The test statistic ;

T = μd / sd/√n

Where, xd = mean of difference

sd = standard deviation of difference

n = sample size

Mean of difference, μd = Σx/n = - 3.13

Standard deviation of difference, sd = 2.91

T = - 3.13 / 2.91/√8

T = - 3.13 / 1.0288403

T = - 3.042

α = 0.01

The Pvalue using a Pvalue calculator ;

Degree of freedom, df = n - 1 ; 8-1 = 7

Pvalue(-3.042, 7) = 0.00939

Pvalue < α ; we reject the null and conclude that sensory measurement are lower after hypnotism

It will take Cromwell approximately 22.2 / 2 = 11.1 years to pay for the land.

We can use the formula for the present value of an annuity to find the number of years it will take Cromwell to pay for the land. The formula is:

\(PV = PMT * [(1 - (1 + r)^{(-n)}) / r]\)

where PV is the present value (in this case, 1,750,000), PMT is the payment amount (100,000), r is the interest rate per period (6.35% / 2 = 0.03175), and n is the total number of periods (in this case, twice the number of years since there are two semiannual payments per year).

Substituting in the values, we get:

1,750,000 = \(100,000 * [(1 - (1 + 0.03175)^{(-2n)}) / 0.03175]\)

Simplifying and solving for n, we get:

\((1 - (1 + 0.03175)^{(-2n} ) / 0.03175 = 17.5\\1 - (1 + 0.03175)^{(-2n)} = 0.03175 * 17.5\\(1 + 0.03175)^{(-2n)} = 0.933\)

Taking the natural logarithm of both sides, we get:

\(-2n * ln(1.03175) = ln(0.933)\\n = ln(0.933) / (-2 * ln(1.03175))\\n ≈ 22.2\)

Therefore, it will take Cromwell approximately 22.2 / 2 = 11.1 years to pay for the land.
