The interest estimated by compounding methods are-

(a) Annual: n = 1; CI = $860

(b) Semiannual: n = 2; CI = $862.

(c) Monthly: n = 12; CI = $865

(d) Daily: n = 365; CI = $855

The formula for computing the compound interest is -

The required equation of the line is given as y = -14x + 45.

A straight line can be written in the form of equation as, y = mx + c.

Two straight lines intersect each other only at one point.

When two straight lines are parallel to each other the angle between them is zero.

Given that,

The slope of the line is -14.

And, the point it passes through is (3, 3).

The equation of the line for given data can be written as follows,

(y - 3)/(x - 3) = -14

=> y - 3 = -14(x - 3)

=> y = -14x + 42 + 3

=> y = -14x + 45

Hence, the equation of the line for the given point and slope can be written as y = -14x + 45.

Answer:

x=2173

Step-by-step explanation:

The linear equation of the relationship is L = -8t + 40.

The amount Austin paid back each week is: $8.

A linear equation is straight line graph, which can be expressed as y = mx + b, in slope-intercept form. In the slope-intercept form, we have:

Slope = change in y / change in x.

Using two pairs of values from the table given, (1, 32) and (2, 24):

Slope (m) = (32 - 24) / (1 - 2)

m = 8/-1

m = -8.

Find the y-intercept (b) by substituting m = -8 and (x, y) = (1, 32) into y = mx + b:

32 = -8(1) + b

32 = -8 + b

32 + 8 = b

40 = b

b = 40

Substitute b = 40 and m = -8 into L = mt + b:

L = -8t + 40

The correct option is the standard deviations of the variables.

What is correlation?

Any statistical relationship between two random variables or bivariate data, whether causal or not, is referred to in statistics as correlation or dependence.

Correlation is a term used to describe the linear relationship between two entities. When using a correlation tool, the variables must be present in quantities of two or more to test their relationship (degree of association).

In order to scale the measurement between two variables connected to a similar sample, the standard deviation measures dispersion.

The variables' standard deviations are the best choice as a result.

Option involving the standard errors of the variables is incorrect because standard error, which stands for standard deviation, determines the relationship between dependent and independent variables.

Option involving the coefficients of variation of two variables is incorrect because the coefficient expressing standard deviation and mean ratio determines how much variation there is.

Option The means of the variables are incorrect because they are not a scale for determining the correlation between two variables.

Hence, the correct option is the standard deviations of the variables.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

The number of chicken sandwiches is 60.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 4 - 6 is an equation.

We have,

Number of ham sandwiches = H

Number of chicken sandwiches = C

Cost of ham sandwiches = $3.50

Cost of chicken sandwiches = $4

Now,

The total number of sandwiches = 110

The total amount earned = $415

Now,

The two equations are:

H + C = 110 _____(1)

3.50H + 4C = 415 _____(2)

From (1) we get,

C = 110 - H _____(3)

Now,

Putting (3) in (2) we get,

3.50H + 4(110 - H) = 415

3.50H + 440 - 4H = 415

-0.5H = 415 - 440

-0.5H = -25

H = 25/0.5

H = 50

Now,

Putting H = 50 in (3) we get,

C = 110 - H

C = 110 - 50

C = 60

Thus,

The number of chicken sandwiches is 60.

The value of r is r = -8/3, for a line that has slope -12, passes through points (-3, -6) and (r, -10)

Slope is a notation that shows that a surface of which one end or side is at a higher level than another surface.

Slope formula = (y₂-y₁)/(x₂-x₁)

Given that,

A line that has slope -12, passes through points (-3, -6) and (r, -10).

To find the slope of the line that passes through points (-3, -6) and (r, -10),

Use slope formula,

m =  (y₂-y₁) / (x₂-x₁)

m = (-10 + 6) / r - (-3)

m = -4 / (r+3)

Since a line that has slope -12 passes through the points (-3, -6) and (r, -10),

Therefore, both will have the same slope,

-4 / (r+3) = -12

r + 3 = 1/3

r = 1/3 - 3

r = -8/3

Based on the z-score, an Endure All battery selected at random has a 10.56% chance of lasting more than 550 hours.

How closely a value relates to the mean of a set of values is expressed by a Z-score.

The Z-score is created using standard deviations from the mean.

A data point's total value is equal to the mean value when the Z-score of the data point is equal to 0.

So, in order to determine how far the raw score deviates from the mean, the Z score is used.

The following steps are used to determine the Z score:

z = (x - μ)/σ

We know that:  x > 550 and μ = 500, σ = 40

z = 550 - 500 / 40

z = 1.25

The graph of the normal distribution indicates:

P(z > 1.25) = 1 - P(z < 1.25)

P(z > 1.25) = 1 - 0.8944

P(z > 1.25) = 0.1056

Therefore, based on the z-score, an Endure All battery selected at random has a 10.56% chance of lasting more than 550 hours.

Answer: X=0

Step-by-step explanation: X is equal to zero. This is the only way the equation can be true.

The required linear functions are A(t) = 50t + 100 and B(t) = 25t + 200  which are represented in the attached graph. Company A is cheaper if the time is less than 4 hours.

As per the given question, we can write the linear functions as:

A(t) = 50t + 100

B(t) = 25t + 200

We can determine time t when both companies charge the same rate by equating the two equations.

50t + 100 = 25t + 200

Subtract 25t from both sides and subtract 100 from both sides

25t = 100

Divide both sides by 25

t = 4

At 4 hours both companies charge the same rate. So Company A is cheaper if the time is less than 4 hours.

After 4 hours, company B is cheaper.

Since both functions are linear, we only need two points to plot each one onto a graph.

Thus, the required linear functions are A(t) = 50t + 100 and B(t) = 25t + 200  which are represented in the attached graph.

Given:

The sum of the digits of a three-digit number is 13.

The tens digit, t, is 1 more than the hundreds digit, h. The units digit, u, is 3 more than the sum of the tens and hundreds digits.

we are asked to determine each digit of the given number:

we frame the equation as:

tens digit (t) = 1+h

hundreds digit (h) = h

units digit (u) = 3+(t+h)

hence,

h + (1+h) + (3+(t+h)) = 13

open the brackets.

h+1+h+3+(t+h)=13

substitute t value from the above mentioned state.

h+1+h+3+((1+h)+h)=13

h+1+h+3+1+h+h=13

arrange the like terms and add.

4h + 5 = 13

4h = 13-5

4h=8

h = 8/4

h = 2

hence we get the hundreds digit as 2.

now substitute it to get t and u value.

t = 1+h

t = 1+2

t = 3

tens digit = 3

u = 3+(t+h)

u = 3+(3+2)

u = 3+5

u = 8
