$\text {Hello! Let's Solve this Problem!}$

$\text {The First Step is to Solve the Parentheses:}$

$\text {90*20=180+60=240}\\\text {20*5=100}$

$\text {Your new Problem should be: 240/4-16+4+100}$

$\text {The Next Step is to Divide:}$

$\text {240/4=60}$

$\text {Your new Problem should be: 60-16+4*100}$

$\text {The Next Step is to Subtract:}$

$\text {60-16=44}$

$\text {Now the Next Step is to Multiply:}$

$\text {4*100=400}$

$\text {The Final Step is to Add:}$

$\text {44+100=}$

$\text {Your Answer should be:}$

AnnyKZ [126]

Answer:

x = 29

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 3 given angles and equate to 180

x + 2x + 2 + 3x + 4 = 180, that is

6x + 6 = 180 ( subtract 6 from both sides )

6x = 174 ( divide both sides by 6 )

x = 29

Consider a total of 1,000 people. If it was said that within 1 deviation (of the mean) of all people like MATH 123, how many of

Lesechka [4]

Answer:

680 students

Step-by-step explanation:

The 68 - 95 - 99.7 rule (empirical rule) states that 68% of the population lies within one standard deviation of the mean, 95% of the population lies within two standard deviations and 95% of the population lies within three standard deviations.

Hence since it was said that within 1 deviation (of the mean) of all people like MATH 123, therefore the number of people that like MATH 123 is:

number of people that like MATH 123 = 68% of the population

number of people that like MATH 123 = 0.68 * 1000

number of people that like MATH 123 = 680 students
