Answer:

a. FALSE

b. FALSE

c. FALSE

d. TRUE

Step-by-step explanation:

Statement a.

2 (3 - 4 y) = 6 - 4 y

use distributive property on the left:

6 - 8 y which is NOT 6 - 4 y then, FALSE statement

Statement b.

3 + 5 (9 + 2 n) = 48 + 5 n

apply distributive property on the left:

3 + 45 + 10 n = 48 + 10 n which is NOT 48 + 5 n then , FALSE statement

Statement c.

9 - 3 (y - 2) = 3 - 3 y

apply distributive property on the left:

9 - 3 y + 6 = 15 - 3 y which is NOT 3 - 3 y then, FALSE statement

Statement d.

3 (6 x - 2) - 7 = 18 x - 13

apply distributive property on the left:

18 x - 6 - 7 = 18 x - 13 which IS the same as 18 x - 13 then , TRUE statement

A production system has a total daily output of 400 units and a total labor of 350 hours, what kind of productivity measure can

fomenos

Answer:

1.14 products per hour of labor

Step-by-step explanation:

To calculate the daily productivity would be the amount of products per hour of labor.

That is: 400 products / 350 hours of labor, and that is approximately 1.14 products per hour of labor.

Which means that for every hour of labor, 1.14 products are produced in one day, which would be a factor of productivity.

A consumer product magazine recently ran a story concerning the increasing prices of CINCO-FONES. The story stated that CINCO-FO

Leviafan [203]

Answer:

Check the explanation

Step-by-step explanation:

We have:

Null Hypothesis:

H o:μ = 215

Alternate Hypothesis:

Η α :μ> 215 This is a one tailed test

Standardized value to be tested:

$\frac{new Mean Value - nullValue}{SE}$ == $\frac{245.23 – 215}{15.62}$ -= 1.93

Since this is a one tailed test, critical t value which occurs at 95% confidence level is 1.943.

Since 1.93 < 1.943, we can say that At α = 0.05, there is insufficient evidence to indicate that the mean price of all digital cameras exceeds $215.00.

To make it sufficient, we need value more than 1.943.

At α = 0.10, critical t value is 1.440 (less than 1.93) which makes it sufficient.

What makes 50.652 rational?

Ivanshal [37]

Remember a rational number is a number that can be written with two whole numbers in a fraction, for example, 0.25 can be written as 1/4 notice how, both, the numerator and denominator are whole numbers AKA Integers(numbers that aren't decimals or fractions).

any number that can't be written by whole numbers in the numerator or denominator is an irrational number, things like Pi, Pi cannot be written by two whole numbers in the fraction.

50.652, is definitely rational because the fraction does not need decimal numbers in the numerator or denominator.

it can be written as:
$50 \frac{50}{50}$ or $\frac{12663}{250}$

notice how neither the numerator or denominators are decimals?
