Answers

The two equations that could be used to find the number of

treats each dog gets is B) 18 / 6 = 3 and 6 X 3 = 18 So, the option B is the correct answer

What is an equation?

Two expressions are combined in an equation using an equal symbol ("="). The "left-hand side" and "right-hand side" of the equation are the two expressions on either side of the equals sign. Typically, we consider an equation's right side to be zero. Since we can balance this by deducting the right-side expression from both sides' expressions, this won't limit the generality.

A condition on a variable is what an equation in algebra is. It can only be satisfied if the variable has a specific value. That indicates that only the value of x = 9 may satisfy the equation 2x - 5 = 13.

There are several sorts of equations as well, including:

Linear equations

Quadratic equations

cube-based equations

Differential equations

Parametric equations

As Tolen has 18 dog treats and he has 6 dogs to feed so each dog will get 3 treats i.e. (18 / 6 = 3) or we can there are 6 dogs and Tolen has 18 dog  treats to finish so he will give 3 dog treats to each dog  i.e.

(6 X 3 = 18)

Supposed that on January 1 you have a balance of $5600 on a credit cars whose APR is 17%, which you want to pay off in 1 year. Assume that you make no additional charges to the card after January 1.

Parts:
A. Calculate your monthly payments.
B. When the card is paid off, how much will you have paid since January 1?
C. What percentage of your total payment from part (b) is interest?

Answers

Answer:

  A.  $510.75

  B.  $6,129.00

  C.  8.63%

Step-by-step explanation:

You want the monthly payments, total amount paid, and fraction going to interest for the payoff of a $5600 credit card balance at an annual rate of 17% interest.

A. Payments

The monthly payments can be found using the amortization formula:

  A = P(r/12)/(1 -(1 +r/12)^(-12)) . . . . . P is the principal amount, r is the rate

This formula gives the monthly payment for payoff in 1 year.

  A = 5600(0.17/12)/(1 -(1 +0.17/12)^-12) ≈ 510.75

The monthly payment is $510.75.

B. Total paid

You will have made 12 monthly payments of $510.75, for a total of ...

  12 ×  $510.75 = $6,129.00

You will have paid $6,129.00.

C. Fraction to interest

The fraction of your total payoff that goes to interest is ...

  (6129 -5600)/6129 = 1 -(5600/6129) ≈ 0.0863 = 8.63%

About 8.63% of your total payment is interest.

__

Additional comment

Spreadsheets and calculator apps can be used to find these values. You need to be careful to specify that payments are made at the end of the month.

The amount to interest is slightly more than half the interest that would be due if the interest rate were used to calculate simple interest. Our answer of 8.63% is slightly higher than 17%/2 = 8.5%, so passes the reasonableness check.

b. An investment worth i costs $10 to withdraw, then the remaining amount is shared

between four people. Suppose each person gets $40. How much was the

investment worth?

Equation:

Solve it:

Answers

Answer:

the equation 10 = x - y

Step-by-step explanation:

Let x represent the initial value of the investment, and let y represent the amount of money that each person receives after the investment is withdrawn.

We know that the cost of withdrawing the investment is $10, so we can write the equation 10 = x - y. We also know that each person receives $40, so we can write the equation y = 40.

We can now solve for x by substituting the value of y into the first equation. Since y = 40, we can substitute 40 for y in the equation 10 = x - y to get 10 = x - 40. Solving this equation for x, we find that x = 50.

Therefore, the initial value of the investment was $50.

Discuss the coordinates of a point P(x, y) on a coordinate plane, and how these can be
described by its distance, r, from the origin and the angle made with the positive x-axis.

Answers

The distance between any coordinate (x,y) and the origin is given by the equation presented as follows:

D = square root of (x² + y²).

The angle between these coordinates and the positive x-axis is given as follows:

Angle = arctan(y/x).

How to obtain the distance and the angle?

The distance between two points on a coordinate line is equivalent to the hypotenuse of a right triangle.

The sides of the triangle are represented by the differences of the x-coordinates and the y-coordinates of each point.

For the origin, the coordinates are (0,0), hence the distance of any point from the origin is given by the equation presented as follows:

D = square root of (x² + y²).

For the angle, we have that:

The opposite side to the angle is the difference between the y-coordinates.The adjacent side to the angle is the difference between the x-coordinates.

Hence the tangent is applied, as follows:

tan(Angle) = y/x

Angle = arctan(y/x).

The time between arrivals of small aircraft at a country airport is exponentially distributed with a mean of one hour.

(a) We will find the probability that more than three aircraft arrive within an hour,

P(X > 3) = 1 - P(X ≤ 3)

             = 1 - (P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3))

             = 1 - [ ( [tex]e^{-4/3}[/tex] 1° / 0!) + ( [tex]e^{-4/3}[/tex] 1¹ / 1!) + ( [tex]e^{-4/3}[/tex] 1² / 2!) + [tex]e^{-4/3}[/tex] 1³/ 3!]

             = 1 - (0.7029)

P(X > 3) = 0.2970

(b) Now we calculate probability that no interval contains more than three arrivals if 30 separate one-hour intervals are chosen,

(1 - P(X > 3)³°) = (1 - 0.2970)³°

                      = 2.56

(c) Let the length of an interval of time is t, the calculation for t is given as;

P(X = 0) = 0.41

[tex]e^{-t}[/tex](t)° / 0! = 0.41

          [tex]e^{-t}[/tex] = 0.41

          - t = ln(0.41)

          - t = -0.891

            t = 0.891 hours

Negative 5 x minus 3.5 greater-than 6.5. Negative 5 x greater-than 10. x greater-than negative 50.

Answers

She should divide both sides by -5 while she multiplied by -5 on other side and she also did not change the > symbol to a < symbol

How to calculate errors did Parul make?

The idea of inequality, which is the state of not being equal, especially in terms of status, rights, and opportunities1, is at the core of social justice theories. However, because it frequently has different meanings to different people, it is prone to misunderstanding in public discourse. However, some distinctions are shared.

We are given

-5x - 3.5>6.5

Since, we have to solve for x

so, we will isolate x on anyone side

step-1:

Add both sides by 3.5

-5x - 3.5+3.5>6.5+3.5

-5x>10

step-2:

Divide both sides by -5

we know that whenever we divide both sides by negative sign , it's inequality gets revered

so, we get

-5x/5<-50/-5

we get

x<10

so,

She should divide both sides by -5 while she multiplied by -5 on other side and she also did not change the > symbol to a < symbol

The complete question is : Parul attempted to solve an inequality but made one or more errors. Her work and the graph she drew are shown below. What errors did Parul make? Check all that apply. She added 3.5 to both sides when she should have subtracted. She should have divided both sides by as her first step. She divided one side by -5 while multiplying the other side by -5. She did not change the > symbol to a < symbol. She used a closed circle instead of an open circle on the number line.

Conduct a test at the a=0.05 level of significance by determining ​(a) the null and alternative​ hypotheses, ​(b) the test​ statistic, and​ (c) the​ P-value. Assume the samples were obtained independently from a large population using simple random sampling.
Test whether p1>p2. The sample data are x1=119​, ​n1=253, ​x2=134, and n2=311.

Answers

a) The hypothesis are given as follows:

Null: [tex]H_0: p_d = 0[/tex].Alternative: [tex]H_1: p_d > 0[/tex].

b) The test statistic is of: z = 0.94.

c) The p-value is of: 0.1736.

What are the hypothesis tested?

At the null hypothesis, it is tested if there is not enough evidence that p1 is greater than p2, that is, if the subtraction is of zero, hence:

[tex]H_0: p_d = 0[/tex].

At the alternative hypothesis, it is tested if there is enough evidence that p1 is greater than p2, that is, if the subtraction is greather than zero, hence:

[tex]H_1: p_d > 0[/tex].

What are the mean and the standard error for the distribution of differences?

For each sample, the mean and the standard error are given as follows:

[tex]p_1 = \frac{119}{253} = 0.4704, s_1 = \sqrt{\frac{0.4704(0.5296)}{253}} = 0.0314[/tex].[tex]p_2 = \frac{134}{311} = 0.4309, s_1 = \sqrt{\frac{0.4309(0.5691)}{311}} = 0.0281[/tex].

Hence, for the distribution of differences, the mean and the standard error are given as follows:

[tex]p_d = p_1 - p_2 = 0.4704 - 0.4309 = 0.0395[/tex][tex]s = \sqrt{s_1^2 + s_2^2} = \sqrt{0.0314^2 + 0.0281^2} = 0.0421[/tex]

What are the test statistic and the p-value?

The test statistic is given by the division of the estimate of the proportion of differences by the standard error, hence:

z = 0.0395/0.0421 = 0.94.

We have a right-tailed test, as we are testing if the mean is greater than a value, with z = 0.94. Hence, looking at the z-table, the p-value is of:

0.1736.
