Step-by-step explanation:

goodjob so correct

Answer:

for number 3, it is D, not C  and you are correct for 4

Step-by-step explanation:

Given:

Principal value = $240,000

Rate of interest = 6% compounded continuously.

Time = 30 years

To find:

The amount after interest.

Solution:

The formula for amount after continuous compounding the interest is:

[tex]A=Pe^{rt}[/tex]

Where, P is principal, r is rate of interest and t is the number of years.

Putting [tex]P=240,000,r=0.06,t=30[/tex], we get

[tex]A=240,000e^{0.06(30)}[/tex]

[tex]A=240,000e^{1.8}[/tex]

[tex]A=1451,915.39146[/tex]

[tex]A\approx 1451,915.39[/tex]

Therefore, Martins will pay $1451,915.39 for the house, including interest.

Answer:

$38

Step-by-step explanation:

$10 × 2= $20

Therefore the first two lines cost $20

$3 for each additional line of text

since the total lines are 8 lines therefore 8 -2=6

$3 × 6=$18

Tolat cost: First two lines + additional lines

$20+$18= $38

Answer:

Question 1: 0.18

Question 2: 87.50%

To find a decimal of a percentage always divide by one hundred.

So :

0.18

To find a percentage from a fraction, divide the numerator [top number] by the denominator [bottom number]  = 0.875

Take the result and multiply by one hundred. 87.5%

Answer:

356.05 cm³

Step-by-step explanation:

We are looking for the volume. The formula is density = mass / volume.

If we plug in our numbers, our formula would be 2.76 = 982.7 / V.

Multiply both sides by V and your formula would be (V) 2.76 = 982.7.

Divide both sides by 2.76 and you would get V = 356.05.

The volume of the given large emerald is required.

The volume of the given large emerald that was discovered in the mine was 356.05 cm³. The calculations to find this value is shown below.

m = Mass of object = 982.7 grams

[tex]\rho[/tex] = Density of the material the object is made of = 2.76 grams over centimeters cubed

The relation between mass, volume and density is given by

[tex]V=\dfrac{m}{\rho}\\\Rightarrow V=\dfrac{982.7}{2.76}\\\Rightarrow V=356.05072\approx 356.05\ \text{cm}^3[/tex]

We want to compare two linear equations and answer some things in regards to these.

So we have two sets of data:

A) First we want to compare the steepness of the lines, it will represent how much money you and your friend gets per week, a more steep line means a larger weekly income.

By the given points, you can see that you have an increase of $60 in 3 weeks, while your friend has an increase of $60 in 4 weeks, thus, your line should be steeper.

B)  We know that for a line that passes through points (x₁, y₁) and (x₂, y₂) the slope is given by:

[tex]s = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

So, for you, the slope is:

[tex]s_y = \frac{\$100 - \$40}{5 weeks - 2 weeks} = \$20\ per \ week[/tex]

For your friend the slope is:

[tex]s_f = \frac{\$120 - \$60}{8 weeks - 4 weeks} = \$15 \ per \ week[/tex]

C) Your friend saves $5 less than you per week.

D) You, by week 5, have $100

So you need to save another $65

And you save $20 per week, so we need to solve:

$20*x = $65

x = $65/$20 = 3.25

Rounding to the next whole number, x = 4

And this is 4 weeks after the 5th week, so you need to save for a total of 9 weeks.

For your friend, he has $120 at the 8th week, then he must save another $45, and he saves $15 per week, so we need to solve:

$15*x = $45

x = $45/$15 = 3

He must save for another 3 weeks, for a total of 11 weeks.

Answer: a. x=3 or 5

Step-by-step explanation:

x^2-8x+15=0

When factoring this equation we need to find 2 numbers that multiply to get positive (15) and add to get negative (-8)

So -3 and -5 fit this description because -3+-5=-8 and -3*-5=15

(x-3)(x-5)=0

Solve for values of x to get x=3 and x=5

so X=3 or 5

Answer:

1.2

Step-by-step explanation:

First, we need to find the mean of the data. We do this by adding all of the given numbers than dividing it by the number of numbers given. For example, we will add 9+7+11+10+8 which is 45. Since there are 5 given numbers, we are going to divide 45 by 5 which is 9. Now, we need to find the difference (subtraction) of all of the numbers in relation to 9. For example, for 9, we do 9-7 which is 2. Keep 2 in mind. Then we do 11-9 which is also 2. 10-9 is 1. 9-9 is 0. And finally, 9 minus 8 is also 1. Then, like what we did before, we need to find the mean of all of these differences. 2 plus 2 plus 1 plus 0 plus 1 is 6. Then, we divide 6 (our total of these differences) by 5 (the number of differences) 6 divided by 5 is 1.2 so there is your MAD and answer.

The mean absolute deviation of the given data is 1.2.

The mean absolute deviation of a dataset is the average distance between each data point and the mean. It gives us an idea about the variability in a dataset.

Here's how to calculate the mean absolute deviation.

Data given: 9, 7, 11, 10, 8

Step 1: Calculate the mean.

[tex]mean = \frac{sum\ of\ observations}{number\ of\ observations} \\\\mean = \frac{9 + 7+11 + 10 + 8}{5}\\ \\mean =9[/tex]

Step 2: Calculate how far away each data point is from the mean using positive distances. These are called absolute deviations.

Data    Distance from mean

9          |9 - 9| = 0

7          |7 - 9| = 2

11          |11 - 9| = 2

10         |10 - 9| = 1

8          |8 - 9| =1

Step 3: Add those deviations together.

Sum of deviations =  0 + 2 + 2 + 1 + 1 = 6

Step 4: Divide the sum by the number of data points.

Mean absolute deviation = [tex]\frac{sum\ of\ deviations}{number\ of\ observations}\\ \\[/tex] = [tex]\frac{6}{5} = 1.2[/tex]
