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. ​

The evening low temperature in New York in the month of February was -7°F. The following day, the
temperature rose to a high of 25°F. What was the change in temperature that day?

Answers

Answer:

32°F

Step-by-step explanation:

Given that,

The low temperature in New York in the month of February was -7°F. The following day, the  the temperature rose to a high of 25°F.

We need to find the change in temperature that day.

Change = final temperature - initial temperatur

Change = 25°F - (-7°F)

= 25 +7

= 32°F

so, the required change in temperature is 32°F.

how many factors of 10 are in 10 of the third power?

Answers

Answer:2 times 5 equals 10

Step-by-step explanation:

"The factors of 10 are 1, 2, 5, and 10. You can also look at this the other way around: if you can multiply two whole numbers to create a third number, those two numbers are factors of the third. 2 x 5 = 10, so 2 and 5 are factors of 10." From ww.infoplease.com great resource

The required factor of 10 in 10 of the third power is 3.

What are the factors?

A number or algebraic expression that evenly divides another number or expression—i.e., leaves no remainder—is referred to as a factor.

Here,

10 of the third power = 10³
10³ = 10×10×10
The expression 10×10×10 has 3, 10's

Thus, the required factor of 10 in 10 of the third power is 3.

Answers

Answer:

x = 25

Step-by-step explanation:

A quadrilateral is inscribed in a circle, so it is a cyclic Quadrilateral.

Opposite angles of a cyclic quadrilateral are supplementary.

Therefore,

3x + 21y = 180°.....(1)

2x + 26y = 180°.....(2)

From equations (1) & (2)

3x + 21 y = 2x + 26y

3x - 2y = 26y - 21y

x = 5y

y = 1/5 x

Plug y = 1/5 x in equation (1)

3x + 21*1/5x = 180

15x + 21x = 180*5

(Multiplying both sides by 5)

36x = 900

x = 900/36

x = 25

Step-by-step explanation:

We need to write the expression for the given statement.

Seven less than the product of a number n and  1 means (n-7).

It is no more than 95. No more than 95 means less than or equal to i.e.

(n-7) ≤ 95

Hence, the above inequality shows the given statement.
