Answer:

Step-by-step explanation:

The number line that represents the solution set for the inequality is the number line on option B.

Option B is the correct answer.

It shows a relationship between two numbers or two expressions.

There are commonly used four inequalities:

Less than = <

Greater than = >

Less than and equal = ≤

Greater than and equal = ≥

We have,

Let's simplify the inequality.

2x - 6 ≥ 6(x - 2) + 8

2x - 6 ≥ 6x - 12 + 8

2x - 6x ≥ 6x - 4

-4x ≥ 6x - 4

-4x - 6x ≥ - 4

-10x ≥ -4

x ≥ 4/10

x ≥ 2/5

x ≥ 0.4

Now,

This number line will start from 0.4 till infinity on the right side of the number line.

Thus,

The number line on option B is the correct answer.

if (20 + 549+ 48574 - 46567476 x 987665) is the calculations of a number of apples, its total value is mathematically given as

X=−4.59930662*10^13

Generally, the equation for the statement is mathematically given as

20 + 549+ 48574 - 46567476 x 987665 +1

Let's equate it to x, Therefore

X= 20 + 549+ 48574 - 46567476 x 987665 +1

Using BODMAS

X= 20 + 549+ 48574 - 4.59930662*10^13 +1

X=49143-4.59930662×10^13

Based on the account receivable balance and the adjustments, the adjusting entries for doubtful debt under various assumptions is:

a. Bad debt is 1/4 of 1% of sales:

= 9,560,000 x 0.25%

= $23,900

b. Debit balance of $11,400:

= Estimated doubtful accounts + Debit balance

= 36,500 + 11,400

= $47,900

c. Credit balance of $4,700 and 1/2 of 1% of sales:

= Sales x 0.50%

= 9,560,000 x 0.50%

= $47,800

d. Credit balance of $4,700 and estimated doubtful of $39,000:

Based on the statistics, an average American spends $299.7 on lotteries each year

The population is given as:

Population = 325 million

23% are under the age of 18.

This means that this category is not eligible to play lotteries.

The eligible population is:

Eligible = (1 - 23%) * 325 million

Evaluate

Eligible = 250.25 million

The total amount is given as:

Total = $75 billion

So, the amount spent by each is:

Amount = Total/Eligible

This gives

Amount = $75 billion/250.25 million

Evaluate

Amount = $299.7

Hence, an average American spends $299.7 on lotteries each year

The hull speed of the Santa Monica in terms of the length, ln of the Nina Pinta is given as a√b where a = 1.34 and b = ln - 10

An equation is an expression that shows the relationship between two or more numbers and variables.

Given that:

v = 1.34√l

where l is the hull length in feet and v is the hull speed in knots.

Santa Monica has a hull length that is 10 ft shorter than that of the Nina Pinta and ln is the length of Nina. Hence:

v = 1.34√(ln - 10) = a√b

The nth term of the arithmetic sequence 300,250,200 is 350-50n if the common ratio is -50

It is defined as the systematic way of representing the data that follows a certain rule of arithmetic.

We have an arithmetic sequence:

300,250,200

The first term a = 300

Common difference d = 250-300 = -50

nth term:

A(n) = a + (n-1)d

A(n) = 300 + (n-1)(-50)

A(n) = 300 -50n + 50

A(n) = 350—50n

Thus, the nth term of the arithmetic sequence 300,250,200 is 350-50n if the common ratio is -50

The 73 customers who spend money in this store if a MOE of at most 0.075 with 80% confidence.

MOE is an error that provides an estimate of the percentage of errors in real statistical data.

The formula for finding the MOE:

MOE = z x s/√n

Where ,

Z = the z-score at the confidence interval

s =  the standard deviation

n = the number of samples.

We have p = 0.50 MOE = 0.075

Z = 1.282 at 80% confidence

0.075 = 1.282 x √0.50(1- 0.50)/ n

After solving,

n = (0.5)(0.5)/(0.0585)²

n = 73

Thus, the 73 customers who spend money in this store if a MOE of at most 0.075 with 80% confidence.
