The volumes of the 20% solution, 35% solution, and 80% solution used by the chemist are 18 liters, 12 liters, and 24 liters, respectively.

The chemist has three different acidic solutions. The first solution contains 20% acid, the second contains 35% acid, and the third contains 80% acid. She created 54 liters of a 50% acid mixture, using all 3 solutions. The number of liters of 80% solution used is 2 times the number of liters of 35% solution used.

Let the amounts of 20% solution, 35% solution, and 80% solution used be x, y, and z. We already know that z = 2y. We can write equations as given below.

The sum of the volumes must be equal to the final volume.

x + y + z = 54

x + y + 2y = 54

x = 54 - 3y

Now we will write the equation using the concentrations of the acid.

50%*54 = 20%*x + 35%*y + 80%*z

27 = 0.2(54 - 3y) + 0.35y + 0.8(2y)

2700 = 20(54 - 3y) + 35y + 80(2y)

2700 = 1080 - 60y + 35y + 160y

1620 = 135y

y = 1620/135 = 12

z = 2y = 2*12 = 24

x = 54 - 3y = 54 - 36 = 18

The Natural Unemployment Rate based on the information is 5%.

The natural rate of unemployment is the lowest unemployment rate when inflation is stable, or the unemployment rate when inflation is not accelerating. The natural rate of unemployment (NAIRU) is the rate of unemployment caused by all factors other than changes in aggregate demand. Potential GDP estimates are based on the long-term natural rate.

The unemployment rate is the proportion of the total labor force that is unemployed but actively looking for work and willing to work. Cyclical unemployment is associated with an industry's business cycle. It is a direct result of a drop in consumer demand, which has resulted in a drop in labor demand. If cyclical unemployment rises, it indicates that the economy is slowing, which is not good.

Cyclical unemployment occurs when labor forces are reduced as a result of business cycles or economic fluctuations. If you are cyclically unemployed, it means that your employer has laid you off to save money during a period of slow business.

In this case, the unemployment will be:

The average of the certain set of data can be calculated by dividing the sum of the given numbers/data by their count.

(a) In this item, we are given with: -0.05, 0.09, -0.04, -0.08

Their sum is as follows:  

                S = (-0.0.5) + (0.09) + (-0.04) + (-0.08)

                  S = -0.08

Then, divide the sum by 4.

                  M = -0.08 / 4 = -0.02

b. The answer to this question can be calculated through the equation below,

                    M₂ = (S + F) / 5

Substituting the known values,

                 -0.01 = (-0.08 + F) / 5

the value of F is equal to 0.03.

Answer:

15a: -0.02 15b: 0.03

Step-by-step explanation:

15a.

To find the mean, you need to add the values together and divide by the number of values.

(-0.05+0.09+-0.04+-0.08)/4

Simplify:

(-0.05+0.09-0.04-0.08)/4

(-0.05+0.09-0.12)/4

(0.09-0.05-0.12)/4

(0.04-0.12)/4

-0.08/4

-0.02

15b.

let's say the change for Friday is "x"

insert the numbers and add in -0.08 from earlier:

(-0.08+x)/5=-0.01

rearrange (-0.08+x):

(x-0.08)/5=-0.01

multiply both sides by 5:

x-0.08=-0.05

add 0.08 to both sides:

x=0.03

The length of the swimming pool is 30 feet

The width of the swimming pool is 15 feet

The volume of the swimming pool is 16875 gallons

Given,

Length of the rectangular swimming pool = 2x

Width of the rectangular swimming pool = x

A small concrete walkway surrounds the pool.

The width of the walkway = 2 feet

The area of the walkway = 196 square feet

We have to find the dimensions of the pool;

Here,

Area of rectangle = length x width

Area of walkways = (4x + 8x) + 4 x 4 = 196

12x + 16 = 196

12x = 196 - 16

12x = 180

x = 180/12

x = 15

That is,

Width of the pool is 15 feet

Length of the pool = 2 × x = 15 x 2 = 30 feet

Now,

If the depth of the pool is 6 feet, we have to find the amount of water that the pool can hold if the height of water is 1 foot below the top of the pool.

That is,

Volume of pool = length x width x depth

Here, depth = 6 - 1 = 5 feet

So,

Volume = 15 x 30 x 5 = 2250 cubic feet

(80.55, 77.45).

Following are the calculation to the confidence interval :

Given that,

σ = 15

n = 430

X = 79

Here C = 97% = 0.97

⇒ α = 1 -C = 1 - 0.97 = 0.03

∴ Zₙ =  Zₙ/2 = Z₀.₀₁₅ = 2.17

Now,

97% confidence interval,

C.I = X ± σ/√n

     = 79 ± 2.17 × (15/√430)

     = 79 + 2.17 × (15/ 21)                [taking round figure of √430=2.0736441]

     = 80.55

Now taking the negative sign,

Solving an equation we will see that x = 13, then the measure of interior angle G is 63°.

Here we have the 3 interior angles of a triangle defined with a variable x.

m∠E = (5x + 6)°

m∠F = (4x - 6)°

m∠G = (5x - 2)°

Now, remember that the sum of the interior angles of a triangle is always equal to 180°.

Then we can write:

(5x + 6)° + (4x - 6)° +  (5x - 2)° = 180°

We can solve this for x.

14x - 2 = 180

14x = 180 + 2

x = 182/14 = 13

Now that we know the value of x, we can find the value of angle G.

Mia's error in her thinking was that she interchanged the coordinate of both the x- and y-axis. Also, the point would actually be located at (5, 8).

In Mathematics, a reflection across the x-axis would maintain the same x-coordinate while the sign of the y-coordinate would change from positive to negative. Therefore, a reflection across the x-axis is given by this transformation rule:

(x, y)                   →               (x, -y)

In Geometry, a reflection across the y-axis of a graph is given by this transformation rule (x, y) → (-x, y).

(x, y)                   →               (-x, y)

(-5, -8)                   →            (5, -8)

Next, we would apply another reflection across the x-axis of a graph as follows:

(x, y)                   →               (x, -y)

Answer:

ones: 0

tenths: 9

thousandths: 3

Step-by-step explanation:

Because 0 is at the beginning of the whole "part" of the number, it is a "one" in place value (confusing right??) for example, in the number 54,743, 3 would be the digit in the ones place.

Because 9 is one decimal place across the example number, it is a tenth - because you would need 10 lots of 0.1 in order to make a whole number.

Because 3 is three decimal places across the example number, it is a thousandth - because you would need 1000 lots of 0.001 to make a whole number.

A good way of remembering these decimal place values is by using the number of zeros after 10, 100, 1,000, 10,000, and so on (one zero is a ten-th, two zeros is a hundred-th, etc, etc.)

The probability of each outcome in the sample space = 1/16

The probability of getting a sum of 5 = 1/4

Step-by-step explanation:

We have been given a four-sided die is a pyramid whose four faces are labeled with the numbers 1, 2, 3 and 4

sample space = {(1,1), (1,2), (1,3), (1,4), (2,1),(2,2), (2,3), (2,4),(3,1), (3,2), (3,3), (3,4), (4,1), (4,2), (4,3), (4,4)}

Two fair 4-sided dices are rolled and all sixteen possible outcomes are equally likely.

The possible outcomes can be deduced by making combinations of different faces with a particular face.

given that each of the outcomes in the sample space is equally likely. So the probability of each outcome in the sample space is the same.

now we find the probability of each of the outcomes in the sample space

(a) when two dices are rolled, we have n(s) = 4*4=16

the chances of getting the outcome as (1,1) n(a) = 1

the probability of getting the outcome as (1,1) p(a)= n(a)/n(b)

p(a) = 1/16

so the probability of each outcome in the sample space = 1/16

(b) P(A) is the probability of getting 5 as a sum

   P(A) = Total outcomes with 5 as a sum/Total outcomes

  Total outcomes with 5 as sum= 4

  Total outcomes= 16

  P(A)=4/16=1/4
