A company's human resources (HR) department wants to find out what proportion of the company's 1,500 employees regularly visit the in-office recreational room. Throughout a week, HR assistants randomly handed out surveys to employees as they entered the office building every day, until 400 different employees confirmed or denied they visited the recreational room on a regular basis. The survey found that over 30% of the employees who completed the survey visit the recreational room on a regular basis. Which assumption can be made regarding the proportion of all the employees who visit the recreational room on a regular basis?

А. No assumptions can be made about the approximate proportion of all employees who visit the recreational room because the sample is blased.
B. The approximate proportion of all employees who visit the recreational room will be similar to the sample proportion because the sample accurately represents the population.
C. The approximate proportion of all employees who visit the recreational room will be greater than the sample proportion because it is a larger group of employees.

what solution is -5m=8m-2

Answers

Answer:

m=2/13

Step-by-step explanation:

Given function:

-5m=8m-2

Subtract middle value from both side:

[tex]-5m-8m=8m-2-8m[/tex]

Combine like terms:

[tex]-13m=-2[/tex]

Divide both sides by the same term:

[tex]\frac{-13}{13}=\frac{-2}{-13}[/tex]

Divide the terms:

[tex]=\frac{2}{13}[/tex]

Therefore, m=2/13.

Trapezoid: b1 =3m; b2 = 4m
A= 7m 2 What the next missing dimension?

Answers

9514 1404 393

Answer:

  h = 2m

Step-by-step explanation:

We can put the given values into the area formula and solve for the missing one.

  A = (1/2)(b1 +b2)h

  7m²= (1/2)(3m +4m)h

  7m² = (7/2)m·h

  (7m²)(2/(7m)) = h = 2m

The missing height is 2 m.
