Which graph is correct?

The correct statement is f(x)=33(1.32)^(x). .

The original statement is false because it does not accurately represent the increase in the number of weekly flu tests. The original statement suggests that the number of tests decreases by 32% each week, which is not the case.

To accurately represent the increase in the number of weekly flu tests, we need to use the growth factor of 1.32, which is equivalent to 100% + 32%. This means that the number of weekly flu tests increases by 32% each week, as stated in the problem.

Therefore, the correct statement is f(x)=33(1.32)^(x).

Therefore , the solution of the given problem of graph comes out to be option A f(n) = 7 - 2(n-1)

Theoretical physicists use graphs to analytically chart or visually represent claims rather than values. A graph point typically depicts the relationship between any number of things. A specific type of non-linear train assembly made up of clusters and lines is known as a graph. Glue should be used to connect the networks, also referred as the boundaries. In this network, the nodes had the numbers 1, 2, 3, and 5, whilst edges had the numbers 1, 2, 3, and 4, as well as the numbers (2.5), (3.5), (4.5), and yet also (4.5). (4.5).

Here,

We can use the following method to determine the general term of an arithmetic series:

=> f(n) = a + (n-1)d

where the usual difference is "d" and "a" is the first term.

Since the series begins at 7, "a" is 7, as shown by the graph. Additionally, since each term reduces by 2, we can see that the common difference is 2.

Step-by-step explanation:

The sample size that would be required to estimate the confidence interval with a margin of error of 1% is given as follows:

n = 9604.

A confidence interval of proportions has the bounds given by the rule presented as follows:

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which the variables used to calculated these bounds are listed as follows:

The confidence level is of 95%, hence the critical value z is the value of Z that has a p-value of [tex]\frac{1+0.95}{2} = 0.975[/tex], so the critical value is z = 1.96.

The margin of error is modeled as follows:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

We have no estimate of the proportion, hence it is used as follows:

[tex]\pi = 0.5[/tex]

The margin of error is of M = 0.01, hence the sample size is obtained as follows:

[tex]0.01 = 1.96\sqrt{\frac{0.5(0.5)}{n}}[/tex]

[tex]0.01\sqrt{n} = 1.96 \times 0.5[/tex]

[tex]\sqrt{n} = 98[/tex]

By evaluating the function in j = 1, we conclude that each bottle costs 80 cents.

We know that the total cost in dollars can be represented by the linear equation:

C(j) = 0.8*j

Where C is the cost, and j is the number of juice bottles bought.

Then to get the cost of each bottle, we can evaluate the function in 1, which means buying only one.

C(1) = 0.8*1 = 0.8

So each bottle costs $0.80 (or 80 cents).

(a)  The future value of the investment if interest is compounded semiannually is $24,840.28.

(b) The future value of the investment if interest is compounded quarterly is $25,025.68.

(c) The future value of the investment is $185.40 greater when the interest is compounded quarterly.

The future value of an investment can be calculated using the formula FV = P(1 + r/n)^(nt), where FV is the future value, P is the principal amount deposited, r is the annual interest rate, n is the number of times interest is compounded per year, and t is the number of years the investment is held.

If the interest is compounded semiannually, then n = 2. Plugging in the given values, we get:

FV = 18000(1 + 0.04/2)^(2*9)

FV = 18000(1.02)^18

FV = $24,840.28

So the future value of the investment if interest is compounded semiannually is $24,840.28.

If the interest is compounded quarterly, then n = 4. Plugging in the given values, we get:

FV = 18000(1 + 0.04/4)^(4*9)

FV = 18000(1.01)^36

FV = $25,025.68

So the future value of the investment if interest is compounded quarterly is $25,025.68.

To find out how much greater the future value of the investment is when the interest is compounded quarterly, we can subtract the future value when interest is compounded semiannually from the future value when interest is compounded quarterly:

$25,025.68 - $24,840.28 = $185.40

So the future value of the investment is $185.40 greater when the interest is compounded quarterly.

To find the number of degrees for each part of the museum visitors graph, we need to know the total number of visitors for that month. Let's assume that the total number of visitors for the month is 10,000.

Age 18 and under:

Let's assume that the number of visitors aged 18 and under is 3,000. To find the number of degrees for this section of the graph, we need to use the formula: (Number of visitors in the age group / Total number of visitors) x 360 degrees. So, (3000/10000) x 360 = 108 degrees.

Age 19 – 44:

Let's assume that the number of visitors aged 19-44 is 5,000. Using the same formula as above, we get (5000/10000) x 360 = 180 degrees.

Age 45 – 64:

Let's assume that the number of visitors aged 45-64 is 1,500. Using the same formula as above, we get (1500/10000) x 360 = 54 degrees.

Age 65 and over:

Step-by-step explanation:

The difference of the two polynomials is 7x^(4) - 9x - 23.

The difference of the two polynomials (19x^(4)-17x-18)-(12x^(4)-8x+5) can be found by subtracting the corresponding terms of the two polynomials.

Subtract the first term of the second polynomial from the first term of the first polynomial: 19x^(4) - 12x^(4) = 7x^(4)

Subtract the second term of the second polynomial from the second term of the first polynomial: -17x - (-8x) = -17x + 8x = -9x

Subtract the third term of the second polynomial from the third term of the first polynomial: -18 - 5 = -23

Write the resulting polynomial by combining the terms  7x^(4) - 9x - 23

Therefore, the difference of the two polynomials is 7x^(4) - 9x - 23.

Answer:4. (a) BMN = 75°(b) AMP = 105°Explanation:Given that ABC is an isosceles triangle with base BC, and ABC = 75°. Also, BC = MB = PM and MN || BC.(a) To find BMN, we can use the fact that MN || BC. This means that ∠BMN = ∠ABC = 75°. Therefore, BMN = 75°.(b) To find AMP, we can use the fact that BC = MB = PM. This means that triangle BMP is an isosceles triangle with base MP. Since BMN = 75°, we can find ∠BMP by using the fact that the sum of the angles in a triangle is 180°:∠BMP = (180° - 75°)/2 = 52.5°Now, we can find AMP by using the fact that the sum of the angles in a triangle is 180°:AMP = 180° - 75° - 52.5° = 52.5°Therefore, AMP = 105°.

(a) The angle BMN is 30°.

(b) The angle AMP is 15°.

The total angle of a triangle is 180°.

We have an isosceles triangle ABC with base BC and ∠ABC is 75°. We construct point M on AC and N, P on AB. It makes BC = MB = PM and MN || BC.

Since ABC is an isosceles triangle, ∠ACB is also 75°. See the picture attached!

Since BC = MB, the triangle MBC is isosceles with base MC. So, BMC is 75°.

The angles of triangle MBC will sum up to 180°. So,

∠MBC = 180 - (75 + 75) = 30°

The angle BMN and MBC is alternate interior angles, so

∠BMN = ∠MBC = 30°

Now, we have ∠NBM = 75 - 30 = 45°. Since MB = PM, it makes BMP an isosceles triangle. The angle BPM will be the same with PBM. It is 45°.

The angle PMN will be

= 180 - (45 + 45 + 30)

= 60°

The angle CMB, BMN, NMP, and AMP are supplementary. So, the angle AMP is

= 180 - (75 + 30 + 60)

= 15°

Triangle AXC is congruent to triangle AYB by the SAS Congruence Criteria.

In geometry, two triangles are said to be congruent if they have the same shape and size. More specifically, two triangles are congruent if all three sides and all three angles of one triangle are equal to the corresponding sides and angles of the other triangle. When two triangles are congruent, they can be superimposed on top of each other, and all corresponding parts of the triangles will match exactly.

There are several ways to prove that two triangles are congruent, including using the side-angle-side (SAS) theorem, the angle-side-angle (ASA) theorem, the side-side-side (SSS) theorem, and the hypotenuse-leg (HL) theorem.

Given that |AB|=|CD| and triangle ABC is isosceles.

We need to prove that triangle AXC = triangle AYB.

y = 26/90

To solve this system of equations using elimination, we will add the two equations together and rearrange the terms.

2y = x - 5

2y = x + 5

Add the equations together:

2y + 2y = x - 5 + x + 5

4y = 2x + 0

Rearrange the terms:

4y - 2x = 0

We will now use this equation and the equation x + 2y = 13 to solve for x and y.

Substitute 4y - 2x = 0 into x + 2y = 13:

x + 2(4y - 2x) = 13

x + 8y - 4x = 13

Rearrange the terms:

5x + 8y = 13

Substitute 4y - 2x = 0 into 5x + 8y = 13:

5x + 8(4y - 2x) = 13

5x + 32y - 16x = 13

Rearrange the terms:

21x + 32y = 13

Divide by 21:

x + (32/21)y = 13/21

Rearrange the terms:

x = 13/21 - (32/21)y

Substitute x = 13/21 - (32/21)y into 4y - 2x = 0:

4y - 2(13/21 - (32/21)y) = 0

4y - (26/21) + (64/21)y = 0

Rearrange the terms:

(90/21)y = 26/21

y = (26/21) / (90/21)

y = 26/90

Substitute y = 26/90 into x = 13/21 - (32/21)y:

x = 13/21 - (32/21)(26/90)

x = 13/21 - (832/1890)
