6,000 is invested in an account that earns 4.5% annual interest, compound quarterly. What is the value of the account after 8 years?

Answer:

choice A:   y = 25*x

Step-by-step explanation:

A proportional relationship between x and y  would be  y = 25*x

because   y/x = 25  (a constant)

We could say that   y = 2x  + 0.5   can be a proportion relationship,  but not between y and x directly.

y=  2* x  +  2* (1/4)  =  2* (x + 1/4)

and get :    y / (x + (1/4) )  = 2     y  and  (x + (1/4)) are in a proportional relationship,  except it would not be y and x  .

A) y = 2 5 x

Answer:

27

Step-by-step explanation:

Those angles are co interior, and thus add up to 180°. So therefore:

(x+72) + 3x = 180

simplified:

4x+72 = 180

so 180 - 72 = 108

4x = 108

x = 27

Answer:

E2020

Step-by-step explanation:

The infinite sequence can be written as -2, 4, -6, 8 ..... with common difference -2.

In a geometric sequence, the ratio of two consecutive terms are always equal.

The general expression for the nth term is given as aₙ = a₁ × rⁿ⁻¹ .

The sum of n terms for this sequence is given as Sₙ = (rⁿ - 1)/(r - 1).

The expression for the general term for the given sequence is as below,

aₙ = (-1)ⁿ2n

The various terms can be written for different values of n as follows,

⇒ a₁ = (-1)¹ × 2 × 1 = -2

⇒ a₂ = (-1)² × 2 × 2 = 4

⇒ a₃ = (-1)³ × 2 × 3 = -6

⇒ a₄ = (-1)⁴ × 2 × 4 = 8

The common ratio can be given as a₂/a₁ = 4/-2 = -2

Hence, the given infinite sequence can be written as -2, 4, -6, 8 ..... with common ratio -2.

Step-by-step explanation:

Answer:

20% increase

Step-by-step explanation:

1- New number-original number

2- number increased divided by new number then multiply by 100

15-12= 3

3 divided by 15= 0.2

0.2 times 100= 20%

If an original quantity is 12, and the new quantity is 15, then the percentage increase is 25%.

Given that, an original quantity is 12, and the new quantity is 15.

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

Here,

Percentage increase = (New quantity - Original quantity)/Original quantity ×100

= (15-12)/12 ×100

= 3/12 ×100

= 0.25×100

= 25%

Therefore, if an original quantity is 12, and the new quantity is 15, then the percentage increase is 25%.

Answer:

0.013 M NaOH

Step-by-step explanation:

HCL + NaOH = NaCL + water

The mole ratio of acid and base is 1:1

Molarity is equal to the moles of solute divided by the liters of solution

Solute mole = 12.5 × 10^-3 × 0.3

= 0.003075

To neutralize 0.00375mol of HCl, 0.00375 mol of NaOH will be required. Since molarity is moles per liter, divide this amount of moles by the volume in liters:

Molarity = 0.00375/285 × 10^-3

Molarity = 0.0131 M

The molarity concentration of the NaOH solution is 0.013M NaOH

The equation of reaction is given as:

[tex]HCl + NaOH >>>>>> NaCl + H_2O[/tex]

Concentration of Hcl, [tex]C_{Hcl}=0.30M[/tex]

Volume of Hcl, [tex]V_{HCl}=12.5mL[/tex]

Concentration of NaOH = [tex]C_{NaOH}[/tex]

Volume of NaOH, [tex]V_NaOH = 285mL[/tex]

From the equation of reaction:

Number of moles of Hcl, [tex]n_{HCl}=1[/tex]

Number of moles of NaOH, [tex]n_{NaOH}=1[/tex]

The formula for neutralization is given as:

[tex]\frac{C_{HCl}V_{HCl}}{C_{NaOH}V_{NaOH}} = \frac{n_{HCl}}{n_{NaOH}}[/tex]

Substitute the values of the parameters

[tex]\frac{0.30(12.5)}{C_{NaOH}(285)} =\frac{1}{1} \\\\C_{NaOH}(285) = 0.30(12.5)\\\\C_{NaOH}(285) = 3.75\\\\C_{NaOH}=\frac{3.75}{285} \\\\C_{NaOH} = 0.013M[/tex]

The molarity concentration of the NaOH solution is 0.013M NaOH

12 multiple choice questions

Step-by-step explanation:

The system of equations is:

m + t = 19 (quantity of questions)

6m + 4t = 100 (point value)

We use elimination to solve.

Multiply everything in the first equation by 4.

4m + 4t = 76.

subtract that from the second equation.

2m = 24

Divide both sides by 2.

m = 12

Answer:

Step-by-step explanation:

Let x be the number of true or false questions.

Let y be the  number of multiple choice questions

Total questions = 19

x + y = 19   ---------------(i)

Total points = 100

4x + 6y = 100  ---------------(ii)

Multiply equation (i) by (-4).

(i)*(-4)            -4x - 4y = -76

(ii)                  4x + 6y = 100   {Now add. thus x will get eliminated}

                            2y = 24

y = 24/2

y= 12

In this situation, where the price of the soda remains constant regardless of the number of refills, the slope of the function representing this scenario is 0.

In mathematics, the slope of a function can be thought of as the rate of change of the dependent variable (in this case, cost) in relation to the independent variable (in this case, number of refills). Given that the price for the soda remains constant at $3 regardless of the number of refills, the slope would be 0. This is because the cost (the y-value) does not change as the number of sodas (the x-value) increases. Thus, the correct answer is 1) 0.

Answer:

32 cubic meter

Step-by-step explanation:

Volume  for any pyramid  is given by  following expression

volume of pyramid = 1/3( area of base of pyramid * height of pyramid)

________________________________

In the problem

base area of pyramid = 24 sq. m

height = 4 m

Therefore substituting the above given value in formula for volume of pyramid we have

volume of pyramid = 1/3( 24 sq. m * 4 m) = 8 sq. m * 4 m   (since 24/3 = 8)

volume of pyramid =  32 cubic meter.

Answer:

  -4, 2, 8, 14, 20

Step-by-step explanation:

The rule is called a "position to term" rule. That means the word "position" is being used to identify the location of a term in the sequence. The first term is in position 1, for example. Using the rule that the position is multiplied by 6, then 10 is subtracted, we find the terms to be as follows.

In position 1, the term is ...

  1×6 -10 = -4

In position 2, the term is ...

  2×6 -10 = 2

In position 3, the term is ...

  3×6 -10 = 8

In position 4, the term is ...

  4×6 -10 = 14

In position 5, the term is ...

  5×6 -10 = 20

The first 5 terms are -4, 2, 8, 14, 20.

Answer:

Yes they are independent, because P(girl) ≈ 0.42 and P(girl l plays a sport) ≈ 0.42

Step-by-step explanation:

A.P.E.X

Yes, being a girl and playing a sport are independent events as P(girl) = P(girl plays a sport) = 0.4

The term probability refers to the likelihood of an event occurring. It is a branch of mathematics which deals with finding out the likelihood of the occurrence of an event."

Girl             70                             50                        120

Total          175                            125                       300

Here, Formula for probability of independent events:

"If A and B are independent events then, P(A∩B) = P(A).P(B)"

And, Formula of the probability of an event A is:

⇒ P(A) = n(A)/n(S)

where,  n(A) is the number of favorable outcomes, n(S) is the total number of events in the sample space.

Now, Using the definition of probability:

⇒ P(girl)  = Number of girls/ Number of students

⇒ P(girl) = 120/300

⇒ P(girl) = 0.4      .....(1)

And, we find the probability of girls that play a sport.

Using the definition of probability:

P(girl plays a sport) = Number of girls who plays a sport/ number of students who plays a sport

= 70/ 175

= 0.4    ...(2)

From (1) and (2),

P(girl) = P(girl plays a sport)

Thus, Being a girl and playing a sport are Independent events.
