Answer:

the total payment need to pay is $525

Step-by-step explanation:

Given that

The amount at promissory note issued is $500

The rate of interest is 10%

And, the time period is 180 days

So, the total payment included is

= $500 + ($500 × 10% × 180 days ÷ 360 days)

= $500 + $25

= $525

hence, the total payment need to pay is $525

c) if x=2, then 4x=8

Step-by-step explanation:

There are 9 questions on the test.

Let, the number of multiple-choice questions on the test = m

the number of essay questions on the test = s

m + s = 26  .......(1)

So, We are also told that multiple choice is worth 3 points each, so the total number of points for m questions will be 3m.

As essays are worth 8 points each, so the total number of points for s questions will be 8s.

3m + 8s = 123 .......(2)

Now we will use the substitution method to solve a system of linear equations.

From equation (1) we will get,

m = 26 -s

Substituting this value in equation (2) we will get,

3 * (26- s) + 8s =123

78 - 3s + 8s = 123

5s = 123 -78

5s = 45

s = 45/5 = 9

So, there are 9 questions on the test.

Answer:

A rectangle.  

Step-by-step explanation:

A square would have four congruent sides.  Because this does not and it has the four right angles, it is a rectangle.

Vertical asymptotes of trigonometric functions are generally drawn as dashed lines on the graph to indicate that the function approaches infinity or negative infinity as x approaches a certain value.

The variable typically used when writing the equation of a vertical asymptote is "x" because the vertical asymptote occurs at a specific x-value.

For the function f(x) = tan(x/2), the vertical asymptotes occur when the denominator of the tangent function equals an odd multiple of pi/2, since this results in a division by zero error. Therefore, two vertical asymptotes for this function are:

x = (2n + 1)pi, where n is an integer.

The room air-conditioning system is a closed-loop control system.

A closed-loop control system is a system that continuously monitors and adjusts its output based on a desired reference value. In the case of a room air-conditioning system, it typically includes sensors to measure the temperature of the room and compare it to a setpoint.

The system then adjusts the cooling or heating output to maintain the desired temperature. This feedback mechanism makes it a closed-loop control system.

Let's assume the sum of the scores of the 28 students who took the test yesterday is 28 * 72 = 2016.

We know that the sum of the scores of all 30 students is (28 * 72) + x + y, where x and y are the scores of the two students who took the test this morning.

We also know that the mean of all 30 scores is 73. So we can write an equation:

[(28 * 72) + x + y]/30 = 73

Multiplying both sides by 30, we get:

2016 + x + y = 2190

So, x + y = 174.

We are given that the difference of the two scores is 22, so we can write another equation:

y - x = 22

Solving these two equations simultaneously, we get y = 98 and x = 76.

Therefore, the lower score from this morning is 76.

Answer:

5x^2(2x-7)

Step-by-step explanation:

Hope this helps!

Your answer is option b)

The time at which a star rises shifts approximately 4 minutes earlier each day, due to Earth's orbit around the Sun. Since there are roughly 30 days in a month, we can calculate the change in the rise time of Aldebaran over the course of a month.

Step 1: Calculate the time change over one month
30 days * 4 minutes per day = 120 minutes

Step 2: Convert minutes to hours
120 minutes ÷ 60 minutes per hour = 2 hours

Step 3: Subtract the time change from the current rise time
2:00 am - 2 hours = 12:00 am (midnight)

Therefore, you can expect Aldebaran to rise next month at midnight. The correct answer is b) midnight.

The ability of the normal distribution to approximate the binomial distribution under appropriate conditions justifies the use of the normal distribution for the sampling distribution of the proportion.

A sampling distribution is a statistical probability distribution derived from a larger number of samples gathered from a certain population. The sampling distribution of a particular population is the distribution of frequencies of a range of possible outcomes for a population statistic.

A population is the whole pool from which a statistical sample is selected in statistics. A population can be defined as a large group of people, things, events, medical visits, or measures. A population can thus be defined as an aggregate observation of persons linked by a common trait.

All solutions make sense, so none of them should be eliminated.

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

The polynomial equation is given below.

x³ + 6x² - 40x = 192

Solutions: x = -8, x = -4, and x = 6

Substitute x = -8, then we have

(-8)³ + 6(-8)² - 40(-8) = 192

-512 + 384 + 320 = 192

192 = 192

Substitute x = -4, then we have

(-4)³ + 6(-4)² - 40(-4) = 192

-64 + 96 + 160 = 192

192 = 192

Substitute x = 6, then we have

(6)³ + 6(6)² - 40(6) = 192

216 + 216 - 240 = 192

192 = 192

Step-by-step explanation:

When Substituting a=5 and b=-3, you get:

\(\frac{3(5)-(-3)}{6(-3+5)}\)

which becomes:

\(\frac{15+3}{12} = \frac{18}{12} = \frac{3}{2} = 1.5\)

Answer:

4, 15

Step-by-step explanation:

First of all, simplify the first equation. When you simplify, you get -2x-8 = -16, which you then add 8 to both sides. You get -2x = -8, so you divide both sides by -2 to get 4. In the second equation, you subtract 5 from both sides to get x/3= 5. Multiply both sides by 3 to get the value of x, and you'll get the equation of x=15, which is the answer.

The conditions to check about our sample(s) to use the central limit theorem are c. All of the above

As long as the sample size is sufficient, the central limit theorem states that the sampling distribution of the mean will always be normally distributed. The sampling distribution of the mean will be normal regardless of whether the population has a normal, Poisson, binomial, or any other distribution. The sample size must be sufficient to allow for at least 10 successes and 10 failures to be expected from the sample.

This requirement makes sure that the sample is not biased in favour of one result, enabling a more representative and trustworthy sampling distribution. The condition is largely stated in the same way by statement B, however, it is written more succinctly. It emphasises how crucial it is to have a sizable sample size in order to guarantee that the CLT can be used correctly. Thus, both situations are necessary.

A type II error is a statistical term used to describe the failure to reject a false null hypothesis. It occurs when the null hypothesis is actually false but is not rejected because the statistical test failed to find significant evidence against it.

In other words, it happens when an alternative hypothesis is true, but we fail to reject the null hypothesis.

Types of errors in hypothesis testing

There are two types of errors in hypothesis testing:

Type I error: Rejecting a true null hypothesis

Type II error: Failing to reject a false null hypothesis.Type I error occurs when a true null hypothesis is rejected while Type II error occurs when a false null hypothesis is not rejected. These types of errors are inversely related, meaning that a decrease in one type of error causes an increase in the other.

Step-by-step explanation:

I did the test

Present value of Loan payment 1 = \($1000 / (1 + (0.12/365))^{60\)

Present value of Loan payment 2 = \($1200 / (1 + (0.12/365))^{(-30)\)

The single payment required 90 days from now to pay off the two obligations would be the total present value calculated in Step 3.

To calculate the single payment required to pay off the two obligations with a 12% interest rate, we can use the concept of present value. Present value is the current worth of a future payment, taking into account the interest rate and time.

Let's break down the given information:

Loan payment 1: $1000 due 60 days ago

Loan payment 2: $1200 due in 30 days

To find the single payment required 90 days from now, we need to calculate the present value of each payment and then add them together.

Step 1: Calculate the present value of Loan payment 1.

The time period for Loan payment 1 is 60 days ago.

To bring it to the present, we need to calculate the interest accrued for 60 days at a 12% annual interest rate.

Step 2: Calculate the present value of Loan payment 2.

The time period for Loan payment 2 is 30 days in the future.

To bring it to the present, we need to calculate the interest accrued for 30 days at a 12% annual interest rate.

Step 3: Add the present values of Loan payment 1 and Loan payment 2.

Total present value = Present value of Loan payment 1 + Present value of Loan payment 2
