Answer:

x=-8

Step-by-step explanation:

-3(3x+8)+2=26-3x

We move all terms to the left:

-3(3x+8)+2-(26-3x)=0

We add all the numbers together, and all the variables

-3(3x+8)-(-3x+26)+2=0

We multiply parentheses

-9x-(-3x+26)-24+2=0

We get rid of parentheses

-9x+3x-26-24+2=0

We add all the numbers together, and all the variables

-6x-48=0

We move all terms containing x to the left, all other terms to the right

-6x=48

x=48/-6

x=-8

Answer:

The first rectangle is 3x² - 6x + 13 more square feet then the second rectangle

Step-by-step explanation:

A rule for subtracting polynomials

Steps

At the end of the expression is (7x²- 4x + 12) + -4x² - 2x + 1

At this point you combine like terms like you do with adding polynomials so ( 7x² + (-4x²) is 3x², (-4x) + (-2x) is (-6x), and 12 + 1 is 13) so the final answer would be 3x²-6x+13

The probability of randomly selecting a red six or a black king from a 52-card deck is 1/13.

To find the probability of selecting a red six or a black king from a 52-card deck, we need to determine the number of favorable outcomes (red six or black king) and divide it by the total number of possible outcomes (52 cards).

There are 2 red sixes (hearts and diamonds) and 2 black kings (spades and clubs) in a deck.

Since we want to select either a red six or a black king, we can add these numbers together to get a total of 4 favorable outcomes.

Since there are 52 cards in a deck, the total number of possible outcomes is 52.

Now, we can calculate the probability by dividing the number of favorable outcomes by the total number of possible outcomes: Probability = Number of favorable outcomes / Total number of possible outcomes Probability = 4 / 52 Probability = 1 / 13

Therefore, the probability of randomly selecting a red six or a black king from a 52-card deck is 1/13.

Answer: moderate, C, B

Step-by-step explanation:

A)  A shows a moderate negative correlation.  It is moderate because the scattered points are sort of close to the line so it has moderate/medium correlation.  It is also negative because it has a negative slope

B) C shows the strongest correlation because the points around the line are tight and close.

C)  B should not have been drawn.  The  correlation is very weak.  You do know where the line should be because the points are all over the place.

Using the t-distribution, it is found that:

a. The margin of error is of $122.4.

b. The 95% confidence interval for the population mean amount spent on restaurants and carryout food is of ($1,750.6, $1,995.4).

c. The estimate is the sample mean of $1,873.

The bounds of the confidence interval are given according to the following rule:

\(\overline{x} \pm t\frac{s}{\sqrt{n}}\)

In which the parameters are described as follows:

In the context of this problem, the values of these parameters are given by:

\(\overline{x} = 1873, s = 550, n = 80\)

Hence, for item c, the estimate is of $1,873, as it is the sample mean.

The critical value, using a t-distribution calculator, for a two-tailed 95% confidence interval, with 80 - 1 = 79 df, is t = 1.9905.

The margin of error is given by:

\(M = t\frac{s}{\sqrt{n}}\)

Hence:

\(M = 1.9905\frac{550}{\sqrt{80}} = 122.4\)

The confidence interval is the sample mean plus/minus the margin of error, hence:

The percent increase in the cost of the uniform from last year to this year is 25%.

To find the percent increase in the cost of the uniform from last year to this year, we need to calculate the difference between the two prices, divide it by the original price, and then multiply by 100 to express the result as a percentage.

The difference between this year's price and last year's price is:

$65 - $52 = $13

The original price (last year's price) is $52.

So the percent increase in the cost of the uniform is:

percent increase = (difference / original price) x 100

percent increase = ($13 / $52) x 100

percent increase = 0.25 x 100

percent increase = 25%

Therefore, the percent increase in the cost of the uniform from last year to this year is 25%.

Answer:

15%

Step-by-step explanation:

As we see, by the time one day passes, we have the amount of weeds as 1650 times 0.85 to the power of 1. We can rewrite 0.85 as 85%. That means that 1650 keeps getting multiplied by 85% to the power of as many days that have passed. 85% can be rewritten again to 1 - 15%. We can see in the equation that the population of weeds decreases by 15% as d, increases, and d is the number of days, so the population of the weeds decreases by 15% each day.

The FIFO principle and enter the units with the lower unit cost first in the Cost of Goods Sold Unit Cost column and in the Inventory Unit Cost column.

To determine the cost of goods sold for each sale and the inventory balance after each sale using the first-in, first-out (FIFO) method, we need to follow these steps:

1. Identify the units sold and their respective costs:
  - Start with the units available for sale at the beginning of the year.
  - For each sale, allocate the units sold from the oldest inventory (first-in) at their corresponding cost.

2. Calculate the cost of goods sold (COGS) for each sale:
  - Multiply the number of units sold by their respective cost.
  - This will give you the cost of goods sold for each sale.

3. Update the inventory balance after each sale:
  - Subtract the units sold from the total units available for sale.
  - Multiply the remaining units by their respective cost to get the ending inventory value.

Remember to follow the FIFO principle and enter the units with the lower unit cost first in the Cost of Goods Sold Unit Cost column and in the Inventory Unit Cost column.

The probability that the first student is a boy and the second student is a girl is 7/26.

To answer your question, we'll need to calculate the probabilities for each event and then multiply them together.

Probability of selecting a boy first:
There are 7 boys and 13 students total (7 boys + 6 girls), so the probability is 7/13.

Probability of selecting a girl second:
After selecting a boy, there are now 12 students remaining (6 boys + 6 girls). The probability of selecting a girl is 6/12 (which simplifies to 1/2).

Now, multiply the probabilities together: (7/13) × (1/2) = 7/26

So, the probability that the first student is a boy and the second student is a girl is 7/26.

The worth of the horse is 1800 dollars

Given that a cowboy worked for one year for 19,200 plus a horse.

After 7 months, he quit and was paid 10,450 but got to keep the horse.

We need to find the worth of the horse.

Here, the horse is part of the payment in total, so it has to be used as a variable when setting up the proportion.

Let us consider the net worth of the horse to be H

solving for H,

[19,200 + H] / 12 = [10,450 + H] / 7

Now, cross multiply

134,400 + 7H = 125,400 + 12H

134,400 - 125,400 = 12H - 7H

9,000 = 5H

H = 9,000 / 5

H = $1,800

Hence, the net worth of the horse, H is $1,800.

Step-by-step explanation:

The dilation scaling factor that would map ΔABC to ΔADE is \(k = \dfrac{5}{3}\)

A dilation transformation is one in which the size of the object enlarged or reduced by a scale factor.

Possible parts of the question obtained from a similar question, found online are;

Triangle ΔABC is similar to triangle ΔADE

ΔABC ~ ΔADE

The triangle ΔABC is inscribed in the triangle ΔADE, such that the vertex B is located on the side AD and the vertex C is located on the side AE

The similar relationship between the two triangles indicates that the ratio of the corresponding sides on each triangles have the same values, therefore;

\(\dfrac{AD}{AE}\) = The ratio of the corresponding sides on the triangle ΔABC

\(\dfrac{AD}{AE} = \dfrac{12+8}{18+12} = \dfrac{2}{3} = \dfrac{12}{18} = \dfrac{AB}{AC}\)

Therefore, the corresponding side to AD is AB, and the corresponding side to AE is AC

The scale factor, k, that maps ΔABC to ΔADE, produce the length of AD from AB, or AE from AC as follows;

AD = k × AB

20 = k × 12

Therefore; \(k = \dfrac{20}{12} = \dfrac{5}{3}\)
