Answer:

x = -2,  5.

Step-by-step explanation:

|2x - 3| = 7

2x - 3 = 7

2x = 10

x = 5 or:

2x - 3 = -7

2x = -4

x = -2.

 Use what you've learned in this unit to model the population of Western
azamat

The population function of the Western Lowland Gorillas can either represent population growth or population decay

<h3>How to model the population</h3>

The question is incomplete, as the resources to model the population of the Western Lowland Gorillas are not given.

So, I will give a general explanation to solve the question

A population function can be represented as:

y = a(1 \pm r)^x

Where:

  • The initial population of the Western Lowland Gorillas is represented by (a)
  • The rate at which the population changes is represented by (r)
  • The number of years since 2022 is represented by (x)
  • The population in x years is represented by (y)

From the question, we understand that the population of the Western Lowland Gorillas decreases.

This means that the rate of the function would be an exponential decay i.e. 1 -r

Take for instance:

y = 2000 * 0.98^x

By comparison.

a = 2000 and 1 - r = 0.98

The above function can be used to model the population of the Western Lowland Gorillas

In 1997, the American Diabetes Association (ADA) and the federal government lowered the standard for diagnosing diabetes from a
Klio2033 [76]

Answer:

10 percent

Step-by-step explanation:

- Before 1997, people with a minimum FBGL of 140mg/dl were diagnosed as diabetic

- After 1997, people with a minimum FBGL of 126mg/dl were diagnosed as diabetic

- What is the proportion of people who were not considered diabetic before 1997 but are now considered diabetic (after 1997)?

140 - 126 = 14

In percentage, this proportion is = 14/140 × 100

= 10%

Hence, 10% of the people who were not considered diabetic before 1997 are now or will now be considered diabetic.

1/3 of the guests chose beef
mario62 [17]
Find the common denominator of 3 and 12 which would be 12.
Then we add the 2 fractions together to get 9/12.
Now we know that 9/12 of the guests chose chicken and beef.
We also know that 69 guests is equivalent to 3/12 which can be simplified down to get 1/4.
So now we can do 69x4 to get 4/4 which is also 12/12, the amount of guests .
69x4 is 276
Your final should be 276.

Anna71 [15]
----------------------------------------------------------
Ticket Sellers
----------------------------------------------------------
1 ticket seller  = $10 x 50
1 ticket seller  = $500

12 ticket sellers = $500 x 12
12 ticket sellers = $6000

----------------------------------------------------------
Cleaning person
----------------------------------------------------------
1 cleaning person = $7.50 x 50 
1 cleaning person = $ 375

25 cleaning person = $375 x 25
25 cleaning person = $9375

----------------------------------------------------------
Ushers
----------------------------------------------------------
1 usher = $8.50 x 50
1 usher = $425

15 ushers = $425 x 15
15 ushers = $6375

----------------------------------------------------------
Total
----------------------------------------------------------
$6000 + $9375 + $6375 = $21750

----------------------------------------------------------
Answer: Total monthly salary per month = $21750
