Answer:

x = 1.28

Step-by-step explanation:

We have given an equation.

5.eˣ = 18

We have to find the value of x.

Dividing by 5 to both sides of given equation, we have

(5.eˣ) / 5 = 18 / 5

eˣ = 18 / 5

Taking logarithm to both sides of above equation, we have

ln(eˣ) = ln(18/5)

x(lne) = ln(18/5)

since, lne = 1

x.1 = ln(18/5)

x = ln(18/5)

x = 1.280933 ≅ 1.28 which is the answer.

Answer:

The answer is x = 1.28

Step-by-step explanation:

∵ 5(e^x) = 18

∴ e^x = 18/5 ⇒ insert ln in both sides

∴ ln(e^x) = ln(18/5)

∴ x · ln(e) = ln(18/5)

∵ ln (e) = 1

∴ x = ln(18/5)

∴ x = 1.280933 ≅ 1.28

Martha earned a gross pay of $1,215.60 last week. Using the fact that Social Security tax is 6.2% of gross pay, determine the am

zhuklara [117]

Answer:

c. $75.37

Step-by-step explanation:

Gross pay of Martha = $ 1,215.60

Percentage of Social Security Tax = 6.2%

In order to find the amount of Social Security Tax we need to find out what is 6.2% of $ 1,215.60

6.2% in decimal form will be 0.062

So,

6.2% of $ 1,215.60 = 0.062 x 1,215.60

= $ 75.37

This means, the amount of Social Security Tax is $ 75.37. Therefore, option C gives the correct answer.

The mass of a penny was measured six times. The following data was reported:

Scrat [10]

Answer:

a) 8.103 g

b) 9.2948

c) 0

Step-by-step explanation:

Given:

Data reported:

9.314 g, 9.215 g, 9.323 g, 8.103 g, 9.278 g, and 9.344 g

Now,

All the values except the 8.103 are above 9

Here the data 8.103 varies very much with respect to the other values

Hence,

a) the data 8.103 should be excluded

b) average value of the mass of the penny = $\frac{9.314 + 9.215 + 9.323 + 9.278 + 9.344 }{5}$

= 9.2948 g

c) Deviation = Mean - Data

9.2948 - 9.314 = -0.0192

9.2948 - 9.215 = 0.0798

9.2948 - 9.323 = -0.0282

9.2948 - 9.278 = 0.0168

9.2948 - 9.344 = -0.0492

Thus,

Average deviation from mean = tex]\frac{-0.0192 + 0.0798 -0.0282 + 0.0168 -0.0492 }{5}[/tex]

= 0
