A Union worker is to see an increase in pay of 2.5% per year next year. Her salary is $41,000/yr. If inflation was predicted to be 1.9% for the upcoming year, how much more purchasing power would she have in dollars next year?

Answers

Answer:

i need points rq thanks so much

Step-by-step explanation:

imma go waste these points now

She'll have $246 more purchasing power.

Current salary per year = $41000

Next year salary = $41000 × (2.5% × $41000)

= $41000 + (0.025 × $41000)

= $41000 + $1025

= $42025

Effect of Inflation will be:

= $41000 + (1.9% × $41000)

= $41000 + (0.019 × $41000)

= $41000 + $779

= $41779

Therefore, the difference will be:

= $42025 - $41779

= $246

Use the following dot plot to answer the questions.

What is the mean of the set?

If an additional dot is added to the set in the 3 column, how will the mean change? What will the new mean be?

Answers

Answer:

3.4

Decrease ; 3.375

Step-by-step explanation:

Mean = Σfx / Σf

Σfx = (1 * 2) + (2 * 2) + (3 * 3) + (4 * 9) = 51

Σf = 1 + 2 + 3 + 9 = 15

Mean = 51 / 15 = 3.4

If 1 more dot is added to the 3rd column:

Σfx = (1 * 2) + (2 * 2) + (3 * 4) + (4 * 9) = 54

Σf = 1 + 2 + 4 + 9 = 16

Mean = 54 / 16 = 3.375

(a) Write down an expression, in terms of x, to represent the distance travelled by
Alex in the first 2 hours of his journey

Answers

Answer:

4x + 10

Step-by-step explanation:

Given

Let

[tex]t = time[/tex]

[tex]s = speed[/tex]

So:

[tex]t = 2; s = (2x +5)[/tex] --- first 2 hours

[tex]t = 3; s = (3x -5)[/tex] --- last 3 hours

Required

Distance covered in the first 2 hours

Distance (d) is calculated as:

[tex]Distance = speed * time[/tex]

i.e.

[tex]d = s * t[/tex]

For the first 2 hours, we have:

[tex]t = 2; s = (2x +5)[/tex]

So:

[tex]d = (2x + 5) * 2[/tex]

Open bracket

[tex]d =2x * 2 + 5 * 2[/tex]

[tex]d =4x + 10[/tex]

Hence, the distance covered in 4x + 10

A storage tank contains a liquid radioactive element with a half-life of 96 years. It will be relatively safe for the contents to leak from the tank when 0.02% of the
radioactive element remains. How long must the tank remain intact for this storage procedure to be safe?
The tank must remain intact for lears.
(Round the base of the exponential function to four decimal places. Then round the final answer to the nearest year as needed.)

Answers

Answer:

t = 1180 years

Step-by-step explanation:

We will solve this using the radioactive decay formula which is;

A = A_o × 2^(-t/h)

Where;

A = Amount of liquid remaining after time (t)

A_o = initial amount of liquid at initial time

t = time of decay

h = half-life of the liquid

We have;

A_o = 1(we assume it is 100% which is 1)

A = 0.02% = 0.0002

h = 96 years

Thus;

0.0002 = 1 × 2^(-t/96)

0.0002 = 2^(-t/96)

(-t/96)log 2 = log 0.0002

(-t/96) = (log 0.0002)/log 2

(-t/96) = -12.2877

t = 96 × 12.2877 (negative has canceled out)

t = 1179.6192

To the nearest year gives;

t = 1180 years
