$\ln(1\cdot2^{2} \cdot3^{3}\cdot4^{4} ...\cdot10^{10} )$

Step-by-step explanation:

By logarithm rules

$\ln1+2\ln2+3\ln3+....+10\ln10\\\ln1+\ln2^2+\ln3^3+....\ln10^{10}\\\ln(1\cdot2^{2} \cdot3^{3}\cdot4^{4} ...\cdot10^{10} )$

Find the Error: A student is finding the measures of the angles in a triangle that have the ratio 4:4:7. Find the mistake and co

BaLLatris [955]

Answer:

angles are 48°, 48°, 84°

Step-by-step explanation:

ratio of angles = 4 : 4 : 7 = 4x : 4x : 7x ( x is a multiplier )

the sum of the 3 angles = 180 , then

4x + 4x + 7x = 180 , that is

15x = 180 ( divide both sides by 15 )

x = 12

the student made the error of assuming x = 12 was the size of the 2 equal angles.

the correct angles are

4x = 4 × 12 = 48°

7x = 7 × 12 = 84°

Help me please, you get 50 points. This is easy I just need help

pentagon [3]

Fraction -> Decimal

4/5 = 0.8

1/8 = 0.125

Decimal -> Percent

0.22 * 100% = 22%

0.47 * 100% = 47%

Percent -> Fraction

34% / 100 = 0.34 = 17/50

25% / 100 = 0.25 = 1/4

Fraction -> Percent

1/3 = 0.33... * 100% = 33.3%

2/5 = 0.4 * 100% = 40%

Decimal -> Fraction

0.65 = 65/100 = 13/20

0.4 = 4/10 = 2/5

Percent -> Decimal

81% / 100 = 0.81

4% / 100 = 0.04

Best of Luck!

Mama L [17]

Answer:

Explained below.

Step-by-step explanation:

The human resource department at a certain company wants to conduct a survey regarding worker morale. The department has an alphabetical list of all 4,502 employees at the company and wants to conduct a systematic sample of size 50.

Systematic sampling is a kind of probability sampling method in which individuals from a larger population are nominated according to a random initial point and a static, periodic interval.

(a)

A sample of size 50.

Then the value of <em>k</em> will be: $k=\frac{4502}{50}=90.04\approx 50$

Thus, the value of <em>k</em> is 90.

(b)

Label the employees from 1 to 4502.

And select every 90th employee.

So, the individuals who will be administered the survey are:

90th, 180th, 270th,...
