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.
D. No assumptions can be made about the approximate proportion of all employees who visit the recreational-room because the sample size is too small.
Answer:

Trapezoid: b1 =3m; b2 = 4m
A= 7m 2 What the next missing dimension?
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.
dan buys a car for £2,200 it depreciates at a rate of 0.5% per year how much would it be worth in 6 years
Given:
The initial value of car = £2,200
Depreciation rate = 0.5%
To find:
The worth of car after 6 years.
Solution:
Exponential decay model:
[tex]y=a(1-r)^t[/tex]
Where, a is the initial value, r is the rate of depreciation and t is number of years.
Putting a=2200, r=0.005 and t=6, we get
[tex]y=2200(1-0.005)^6[/tex]
[tex]y=2200(0.995)^6[/tex]
[tex]y=2200(0.9703725)[/tex]
[tex]y=2134.8195[/tex]
[tex]y\approx 2134.82[/tex]
Therefore, the worth of the car after 6 years is £2134.82.
Solve the following quadratic equation.
(1 - 18)2 = 1
OA
x = 19 and x = 17
OB.
x= -19 and x = .17
OC. x= -19 and x = 17
D.
x = 19 and x=-17
Given:
Consider the given equation is
[tex](x-18)^2=1[/tex]
To find:
The values of x.
Solution:
We have,
[tex](x-18)^2=1[/tex]
Taking square root on both sides, we get
[tex]x-18=\pm\sqrt{1}[/tex]
[tex]x-18=\pm 1[/tex]
Adding 18 on both sides, we get
[tex]x-18+18=\pm 1+18[/tex]
[tex]x=\pm 1+18[/tex]
Now,
[tex]x=1+18[/tex] and [tex]x=-1+18[/tex]
[tex]x=19[/tex] and [tex]x=17[/tex]
Therefore, the correct option is A.

How long does it take $150 to grow to $600 at 5% annual percentage rate compounded continously? Round to the nearest whole number. Must show work.
Or, if your money is earning a 5 percent interest rate, you'll double it in 14.4 years (72 divided by 5 equals 14.4). If your money is earning a measly 1 percent interest rate, it will take you—yep, you guessed it—a whopping 72 years to double it.
