The simplify of given equation 11k/ (55k^2+ 22k) is 1/(5k+2).

Given,

[tex]\frac{11x}{55^{2}+22k }[/tex]  We have to simplify in rational expression

The common factor is 11. So, we have to pick the common factor from the equation.

= [tex]\frac{1}{5x + 2}[/tex]

Therefore the simplification of given equation is 1/(5k+2).

Elizabeth would travel a distance of [tex]11\frac{2}{5}[/tex] miles.

The distance between Elizabeth's house and Carson's house = Sum of (the distance between Elizabeth's house and the Library + the distance between the library and Millo's house + the distance between Millo's House and Carson's House). That is:

Total Miles = [tex]6\frac{1}{2}[/tex] + [tex]2\frac{2}{5}[/tex] + [tex]2\frac{1}{2}[/tex]

To calculate the total miles, we need to transform the mixed numbers into fractions. We can do that as:

[tex]6\frac{1}{2}[/tex] = [(6 × 2) + (1)]/2 = 13/2

[tex]2\frac{2}{5}[/tex] = [(2 × 5) + (2)]/5 = 12/5

[tex]2\frac{1}{2}[/tex] = [(2 × 2) + (1)]/2 = 5/2

So, the distance from Elizabeth's house to Carson's House has 57/5 miles, and it is calculated as:

13/2 + 12/5 + 5/2 = 57/5

Then, convert 57/5 into a mixed number, and we get:

57/5 = [tex]11\frac{2}{5}[/tex]

The length of GH is about 7.3 units. The solution has been obtained by using the formula of distance between two points.

What is distance between two points?

The distance between two points in a plane is the length of the line segment separating the two points. Typically, the equation

[tex]d=\sqrt{(x_{2} -x_{1})^{2} + (y_{2} -y_{1})^{2} }[/tex]  is used to calculate the distance between two points. One can use this formula to get the separation between any two points on an x-y plane or coordinate plane.

We are given two points as G(-9,-4) and H(-2,-6)

Using the distance formula,

[tex]d=\sqrt{(x_{2} -x_{1})^{2} + (y_{2} -y_{1})^{2} }[/tex]

[tex]d=\sqrt{(-2 +9)^{2} + (-6 +4)^{2} }[/tex]

[tex]d=\sqrt{(7)^{2} + (-2)^{2} }[/tex]

[tex]d=\sqrt{49 + 4 }[/tex]

[tex]d=\sqrt{53 }[/tex]

d = 7.3 units

Hence, the length of GH is about 7.3 units.

Using exponents rule the missing term in the equation 7^(-147) × 7^(98) = 7^(18) × 7^(-38) ×____ is found to be 7^(-29).

What is an exponent?

The way of representing huge numbers in terms of powers is known as an exponent. Exponent, then, is the number of times a number has been multiplied by itself.

The given expression is - 7^(-147) × 7^(98) = 7^(18) × 7^(-38) ×____

Let the missing term be x.

Then the equation is -

7^(-147) × 7^(98) = 7^(18) × 7^(-38) × x

Since, the base of the exponents is same, so apply the operations on the powers of the base.

The exponent rule is - a^(b) × a^(c) = a^(b + c)

Write the equation according to the rule -

7^(-147 + 98) = 7^(18 - 38) × x

Now perform the arithmetic operation of addition and subtraction -

7^(-147 + 98) = 7^(18 - 38) × x

7^(-49) = 7^(-20) × x

The exponent rule is - a^(b) / a^(c) = a^(b - c)

Write the equation according to the rule -

x = [7^(-49)] / [7^(-20)]

x = 7^[-49 - (-20)]

x = 7^(-49 + 20)

x = 7^(-29)

Therefore, the missing term is x = 7^(-29).

The value of test statistics z=1.04

First, state the null and alternative hypotheses:

[tex]H_o=u_1=u_2\\H_a=u_1 > u_2[/tex]

Use z-statistics:

[tex]z=\frac{x_1-x_2}{y} ------(1)[/tex]

where x₁ and x₂ are the means and:

[tex]y=\sqrt{\frac{s_1^2}{n_1}+\frac{s_2^2}{n_2} }[/tex]

Calculating the value of test statistics:

[tex]y=\sqrt{\frac{(23.53)^2}{47}+\frac{(71.32)^2}{54} }[/tex]

[tex]y=\sqrt{\frac{533.6609}{47}+\frac{5086.542}{54} }[/tex]

[tex]y=\sqrt{11.780+7.460}[/tex]

[tex]y=\sqrt{19.24}[/tex]

y = 4.386

Now substitute the y value in equation (1)

[tex]z=\frac{75.57-71.32}{4.386}[/tex]

z = 1.04

The test statistics is z = 1.04

The decision rule for rejecting the null hypothesis is:  α≤ test statistics

Using the z-score table, it is possible to determine the p-value, which is:

value = 0.877

Comparing the p-value with the level of significance (α = 0.05):

0.877 > 0.05

Therefore, we fail to reject the null hypothesis.

The correct option is Option C - 85.274.94.

The face value of the 10-year term insurance policy on a 25-year-old Female given that the annual premium for the insurance policy of $384.59 is 85,274. 94.

Given:

Annual premium for the insurance policy = $384. 59

According to the chart at the conclusion of the answer, the amount paid per $1,000 of coverage for a female 25 year old for a 10 year policy is 4.51.

Face value = (1,000 x Annual premium) / Amount paid for 25 year old female for 10 year policy)

Face value = (1000 x 384.59) /4.51

Face Value = 384590 / 4.51

We usually cancel out the common factors from both the numerator and the denominator of the fraction we obtained. Numerator is the upper quantity in the fraction and denominator is the lower quantity in the fraction).

Suppose that we've got a = 6, and b= 4, then:

[tex]a:b = 6:2 = \dfrac{6}{2} = \dfrac{2 \times 3}{2 \times 1} = \dfrac{3}{1} = 3\\or\\a : b = 3 : 1 = 3/1 = 3[/tex]

Remember that the ratio should always be taken of quantities with same unit of measurement. Also, ratio is a unitless(no units) quantity.

Given;

Ratio of first line segment = 4.4/6.3

Ratio of other line segment= 14.08/x

Now, to find the value of x

4.4/6.3 = 14.08/x

The number of students who do not buy lunch is 624 students - 420 students = 204 students.

The circle graph represents the proportion of students who buy lunch and those who don't. To find the number of students who don't buy lunch, we need to subtract the number of students who buy lunch from the total number of students.

Since 255° represents the proportion of students who buy lunch, we can use this to find the number of students who buy lunch. To do this, we divide the number of degrees by 360° and multiply by the total number of students, 624:

(255° / 360°) x 624 students = 420 students

The length of the diagonals of the rhombus is 3.5cm.

A rhombus's diagonals are always perpendicular to one another and always the same length. It contains four right angles, hence an acute angle of 840 is an obtuse angle. We are aware that in a rhombus, the diagonal is the hypotenuse of a right triangle, and the other two sides make up each half of the side.

Consequently, we can use the Pythagorean theorem to determine the diagonal's length:

c = √(a² + b²)

where an is the rhombus's half-length side and b is the other half, and c is the length of the diagonal. So we have:

a = (5cm) / 2 = 2.5cm

b = (5cm) / 2 = 2.5cm

c = √(2.5² + 2.5²) = √(6.25 + 6.25) = √12.5 = 3.5cm

Pipes used = 1/2 yards

Pipes left = total pipes bought - she doesn't suit that way

Pipes left = Total pipes available - pipes used

The balloons were never at the same altitude because the gold balloon was already 1515 meters above the purple balloon at the start.

Let t be the number of seconds since the balloons took off, and Hp(t) and Hg(t) be the altitude of the purple and gold balloons respectively at time t.

We know that:

Hp(t) = 0 + 2.5t (the purple balloon starts at sea level and climbs at a rate of 2.5 m/s)

Hg(t) = 1515 + 222t (the gold balloon starts 1515 m above sea level and climbs at a rate of 2*22 m/s)

We want to find the time t when the balloons are at the same altitude, so we can set Hp(t) = Hg(t) and solve for t:

0 + 2.5t = 1515 + 222t

2.5t = 1515 + 222t

2.5t - 222t = 1515

0.5t = 1515 - 1515

t = 0

So the balloons were never at the same altitude because the gold balloon was already 1515 meters above the purple balloon at the start.
