4a square - 9b square - 2a - 3b​

Answer:

No solution.

Step-by-step explanation:

Step 1: Write equation

-3(-x + 4) = 5 + 3(x + 1)

Step 2: Solve for x

Here, we see that x has to equal no solution. No value of x would make the equation true.

Answer:

no solutions

Step-by-step explanation:

distribute the parenthesis

3x - 12 = 5 + 3x + 3

move all variables to one side of the equation and the constants to the other

3x - 3x = 5 + 3 + 12

0 = 20

The statement that is true among the given options is: "The population mean and a sample mean for a sample selected from the population will usually be different values." This statement accurately describes the relationship between the population mean and a sample mean.

In statistics, the population mean refers to the average value of a variable in the entire population, while a sample mean represents the average value of the variable calculated from a subset of the population (a sample). It is important to note that unless the sample is the entire population itself, the sample mean will typically differ from the population mean.

The reason for this discrepancy is due to sampling variability. When we select a sample from a population, we are observing a smaller subset of the whole, which introduces some level of randomness or uncertainty. Different samples from the same population may yield slightly different values for the sample mean.

However, as the sample size increases, the sample mean tends to converge towards the population mean.

In summary, the population mean and sample mean are generally not identical, and their values are likely to differ due to sampling variability. The sample mean provides an estimate of the population mean, and the accuracy of this estimate improves with larger sample sizes.

Answer: x

Step-by-step explanation:

The inverse undos any changes to x, reversing those changes will leave x. Ex: f(x)=x+2. The inverse (from replacing x with y and y with x and solving for y) is h(x)=x-2. Plugging x+2 into h(x) (composition of functions) results in x. 2 and -2 cancel out.

Answer:

Width is 10

Length is 18

Step-by-step explanation:

Perimeter is calculated as 2(w+l) or w+w+l+l. When you put those two numbers into the equation 2(10+18) or 10+10+18+18, you get the exact same answer of 56, and since 10 is eight less than 18, it would be the width.

Answer:

Step-by-step explanation:

perimeter P = 2L + 2W

where

Perimeter P = 56 m

Width W = L - 8 m

find:

length L

width W

solution:

just plugin the values into the formula:

P = 2L + 2W

56 = 2L + 2(L - 8)

56 = 2L + 2L - 16

56 + 16 = 4L

L = 72/4

L = 18 m

solve for W:

substitute L=18 back into the equation W=L-8

W = 18 - 8

W = 10 m

therefore:

length L = 18 m

Width W = 10 m

proof:

56 = 2(18) + 2(10)

56 = 36 + 20

56 = 56 ----- OK

Answer: $24.38

Step-by-step explanation:

So since the cost of a movie ticket is $20 and the cost is predicted to increase by 2% each year over the next 10 years. to find the cost after 10 years you want to solve for x.

so x=20(1.02)^10

20 is the initial cost and 0.02 is the rate of growth. expressed as a decimal number, the base is b=1+0.02=1.02 and the exponent 10 is the number of years

Step-by-step explanation:

someone asked this same question so if you need a better explanation copy and paste your question ito the box but here is how I got that

d=w2+l2=92+402=41

The single payment required 90 days from now to pay off the two obligations, including interest, is approximately $2230.41.

To calculate the single payment required to pay off the two obligations, we need to consider the interest accrued over the specified time period.

Let's break down the problem into two parts:

1. Loan payment of $1000 due 60 days ago:

This payment has already accrued interest for 60 days. To calculate the total amount owed, we need to calculate the interest accrued. The formula to calculate simple interest is:

Interest = Principal * Rate * Time

Here, the principal amount is $1000, the interest rate is 12% (0.12 as a decimal), and the time is 60/365 years (since we're assuming a 365-day year). Using these values, we can calculate the interest accrued as:

Interest1 = $1000 * 0.12 * (60/365)

2. Loan payment of $1200 due in 30 days:

This payment will accrue interest for the remaining 30 days until the agreed focal date, which is 90 days from now. Using the same formula, we can calculate the interest accrued as:

Interest2 = $1200 * 0.12 * (30/365)

To find the total amount required to pay off the two obligations, we sum the principal amounts and the accrued interest:

Total payment = $1000 + Interest1 + $1200 + Interest2

Now, let's calculate the values:

Interest1 = $1000 * 0.12 * (60/365) = $19.18 (approx.)

Interest2 = $1200 * 0.12 * (30/365) = $11.23 (approx.)

Total payment = $1000 + $19.18 + $1200 + $11.23 = $2230.41 (approx.)

Therefore, the single payment required 90 days from now to pay off the two obligations, including interest, is approximately $2230.41.

Step-by-step explanation:

a. The probability that you win on none of your 5 plays is approximately 0.6634. b. The probability that you win 3 or more of your 5 plays of this game is approximately 0.004497.

To solve these problems, we'll use the binomial probability formula.

a. The probability of winning in any one play is 0.08, so the probability of losing in any one play is 1 - 0.08 = 0.92.

The probability of winning on none of your 5 plays can be calculated as the probability of losing on each play, which is 0.92, raised to the power of the number of plays.

P(losing all 5 plays) = (0.92)^5 = 0.6634 (rounded to four decimal places)

Therefore, the probability that you win on none of your 5 plays is approximately 0.6634.

b. To find the probability of winning 3 or more of your 5 plays, we need to calculate the probability of winning 3, 4, or 5 plays and sum them up.

P(winning 3 or more plays) = P(winning 3 plays) + P(winning 4 plays) + P(winning all 5 plays)

P(winning 3 plays) = C(5, 3) *[tex](0.08)^3 * (0.92)^2[/tex]

                  = 10 * 0.000512 * 0.8464

                  ≈ 0.00434 (rounded to five decimal places)

P(winning 4 plays) = [tex]C(5, 4) * (0.08)^4 * (0.92)^1[/tex]

                  = 5 * 0.000032768 * 0.92

                  ≈ 0.000151 (rounded to six decimal places)

P(winning all 5 plays) = [tex](0.08)^5[/tex]

                     ≈ 0.000006 (rounded to six decimal places)

Now we can sum up these probabilities:

P(winning 3 or more plays) ≈ 0.00434 + 0.000151 + 0.000006

                          ≈ 0.004497 (rounded to six decimal places)

Therefore, the probability that you win 3 or more of your 5 plays of this game is approximately 0.004497.
