The value of A and B will be 6 and 3 respectively

The steps are as follow:

Ax +By = 15

Ax - By = 9

2A + B = 15

2A - B = 9

4A = 24

A = 6

2A + B = 15

2(6) + B = 15

B = 3

So the value of A and B will be 6 and 3 respectively

Answer:

62.8 inches

Step-by-step explanation:

c = 2πr

Where,

c = Circumference of a circle

π = pi = 3.14

r = radius = 10 inches

c = 2πr

= 2 × 3.14 × 10

= 62.8 inches

c = 62.8 inches

Therefore,

The circumference of the circle is 62.8 inches

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]

X=5 and 3

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:

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]

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]

Its easy... 5 and 5.04!

Step-by-step explanation:

You have to look at it properly. It says "The value of SQUARE ROOTED K."

So all you have to do is square root them and whatever is in between 2.2 and 2.3 is ur answer. Ur answer 5 and 5.04.

The values of √k that lies between 2.2 and 2.3 is 5 and 5.04.

An equation is an expression that shows the relationship between two or more numbers and variables.

Given that √k falls between 2.2 and 2.3

For k = 1.49, √1.49 = 1.22 which is not between 2.2 and 2.3

For k = 4.8, √4.8 = 2.19 which is not between 2.2 and 2.3

For k = 5, √5 = 2.2 3which is between 2.2 and 2.3

For k = 5.04, √5,04 = 2.23 which is between 2.2 and 2.3

For k = 5.3, √5.3 = 2.302 which is not between 2.2 and 2.3

For k = 6, √6 which is not between 2.2 and 2.3

The values of √k that lies between 2.2 and 2.3 is 5 and 5.04.
