The principal P is borrowed at a simple interest rate r for a period of time t. Find the loan's future value A, or the total amount due at time t. Round answers to the nearest cent. P=$2000, r=%6, T=6 years

Answers

Answer:

$2720

Step-by-step explanation:

Given data

Principal=$2000

r= %6

T= 6 years

The expression for the final amount is

A= P(1+rt)

A=2000(1+0.06*6)

A=2000(1+0.36)

A=2000*1.36

A=2720

Hence the amount is $2720

Sora was given two data sets, one without an outlier and one with an outlier.

Data without an outlier: 108, 113, 105, 118, 124, 121, 109
Data with an outlier: 108, 113, 105, 118, 124, 121, 109, 41

How is the mean affected by an outlier?
The outlier did not affect the mean at all.
The outlier made the mean higher than all the other values.
The outlier made the mean lower than all the other values.
The mean is centered around all the other numbers in both sets of data.

Answers

Answer:

The outlier made the mean lower than all the other values.

Step-by-step explanation:

Mean is a measure of central tendency. It is the average of a set of numbers. It is determined by adding the numbers together and dividing it by the total number

Mean = sum of the numbers / total number

Mean of numbers without the outlier = (108 + 113 +105 + 118 + 124 + 121 +109) / 7 = 114

Mean of numbers with the outlier = (108 + 113 +105 + 118 + 124 + 121 +109 + 41) / 8 = 104.9

the mean with the outlier is lower than any of the numbers

The sum of two numbers is 38. The greater number is 8 more than the other number. Find each number.

Answers

Step-by-step explanation:

Answer:

23 and 15

Step-by-step explanation:

Create a system of equations where x is the greater number, and y is the smaller number.

x + y = 38

x = y + 8

Solve by substitution, by substituting the second equation into the first one, then solving for y:

x + y = 38

(y + 8) + y = 38

Add like terms and solve for y:

2y + 8 = 38

2y = 30

y = 15

Add 8 to this, to find the greater number:

15 + 8

= 23

So, the numbers are 23 and 15.

A box contains 12 cereal bars. The empty box weighs 1.75 oz. The box and the bars weigh 18.55 oz. What is the weight of each cereal bar?
please provide the answer and the equation

Answers

Answer:

Each cereal bar is 1.4 ounces

Subtract the weight of the empty box from the 18.55 (because that's the weight of the box AND the cereal)

You are then left with 16.8 ounces, which is just the weight of the 12 cereal bars.

To find the weight of one cereal bar, assuming that all cereal bars weigh the same, you need to divide 16.8 by 12.

So that results in each cereal bar weighing 1.4 ounces

Are the vectors u1→=<2,3>and u2→=<-3,-2>parallel? Show your work and explain.

Answers

Answer:

Two vectors are parallel if they are scalar multiples of one another. If u and v are two non-zero vectors and u = c v, then u and v are parallel. The following diagram shows several vectors that are parallel.

Step-by-step explanation:

The requried given vectors are not parallel. As their dot product is not zero.

What is a vector?

Vector is defined as the quantities that have both magnitude and direction are called a vector quantity and the nature of the quantity is called a vector.

Two non-zero vectors are parallel if they are scalar multiples of each other. In other words, if one vector is a constant multiple of the other, then they are parallel.

Let k be the scalar multiple such that:

u₁ = k u₂

Substituting the given values of u₁ and u₂, we get:

<2, 3> = k <-3, -2>

Multiplying both sides by -1, we get:

<-2, -3> = k <3, 2>

Now, we can see that the two vectors are not scalar multiples of each other, since there is no value of k that satisfies this equation. Therefore, u₁ and u₂ are not parallel.

We can also verify this by checking their dot product. If the dot product of two non-zero vectors is zero, then they are orthogonal (perpendicular), not parallel. The dot product of u₁ and u₂ is:

u₁ ⋅ u₂ = (2)(-3) + (3)(-2) = -6 - 6 = -12

Since the dot product is not zero, we can conclude that the vectors u₁ and u₂ are not parallel.

In the equation of a line, y = mx + b , what does m stand for? What is the value of m for the line of best fit?
Part D
Now that you know m and b, what is the equation of the line of best fit?

Answers

Answer:

Part A:

Most of the data points are above line m. All of the data points are below line n. The data points are evenly distributed on either side of line l. Therefore, line l is the line of best fit for the data.

Part B:

For the line of best fit, the y-intercept is approximately 10 and the slope is approximately 2 .

Part C:

Y= 2x+10

Step-by-step explanation:

Part A:

Part B:

To find the y-intercept of a line, identify where the line intersects the y-axis. Because the line of best fit is line l, the y-intercept is 10.

To find the slope, choose two points on line l, such as (10,30) and (30,70):

Part C:

To get the equation of the line, substitute the y-intercept, 10, for b and the slope, 2, for m.
