Answer:

The final price of the swimsuit is $84.00.

To calculate the final price, first calculate the original price after the 20% discount:

Original Price x (1 - Discount) = Final Price

$140 x (1 - 0.2) = $112

Then, calculate the final price after the additional 40% discount:

$112 x (1 - 0.4) = $84.00

Answer:

h + 4

Step-by-step explanation:

given

f(x) = x² - 2x + 1

then

f(3 + h)

= (3 + h)² - 2(3 + h) + 1 ← expand (3 + h)² using FOIL

= 9 + 6h + h² - 6 - 2h + 1 ← collect like terms

= h² + 4h + 4

and

f(3) = 3² - 2(3) + 1 = 9 - 6 + 1 = 4

then difference quotient

[tex]\frac{f(3+h)-f(3)}{h}[/tex]

= [tex]\frac{h^2+4h+4-4}{h}[/tex]

= [tex]\frac{h^2+4h}{h}[/tex] ← factor out h from each term on the numerator

The ratio of the lengths of the opposing side and the hypotenuse of a right-angled triangle is known as the sine function in trigonometry. Use the sine function to calculate the unknown side or angles of a right triangle.

The sine of the angle is the ratio of the hypotenuse to the perpendicular of a right-angled triangle. The formula for sin is sin = Perpendicular / Hypotenuse.

General sine function a sin b (x - c) + d

amplitude = absolute value of a

b = 2π / period

A. He arrives at Nuneaton at 14:01; B. The trip was 100 minutes. C. Vikram will not be on time to catch the train.

Based on the table, Jum should have arrived at 13:54; however, we know he was 7 minutes late. Then, let's calculate the time:

13:54 + 7 minutes = 14:01

Let's calculate the time using the arrival and departure times:

14:01 - 12:21 = 100 minutes considering there are 39 minutes till 13:00 and 61 minutes until 14:01 (39+61 = 100)

Vikram arrived on time in Nuneaton, which means he arrived at 10:28 and then, he was there for 3 hours and 30 minutes:

10:28 + 3:30 = 13:58

This shows he will not be on time to catch the 13:54 train

Where:

Information about the problem:

Applying the combination formula we have:

C(n/r) = n! / [(n-r)! *r!]

C(4/2) = 4! / [(4-2)! *2!]

Given that the adult tickets sold were 5 less than 3 times the number of student tickets and adult tickets sold for $9 each, we can set up the equation:

6s + 9(3s - 5) = 1506

This simplifies to:

6s + 27s - 45 = 1506

To find the number of student tickets sold, we can solve this equation for s.

Combining like terms:

33s - 45 = 1506

Adding 45 to both sides:

33s = 1551

Dividing both sides by 33:

s = 46.9

The number of student tickets sold is 46.9.

Please note that this is not an integer and it is not possible to have a fraction of a ticket, therefore it is not accurate.

If an object is moving in a uniform circular motion, its period is given by the time interval for the object to make one revolution.

The movement of a body follows in a circular path is called a circular motion. The motion of a body moving with a constant speed along a circular path is called Uniform Circular Motion.

In the case of uniform circular motion, the acceleration is:

ar=v2/r=ω2r

If the mass of the particle is m, we can say from the second law of motion that:

F=ma

mv2/r= mω2r

With the number of revolutions displacements from the initial point to the final point also changes. As both these factors change velocity also changes. But in that uniform circular motion what remains constant is speed.

The correct answer is B. While the measures of variation can be found they do not make sense because the data are nominal, they don't measure or count anything.

Any difference between the individuals in a species or between groups of organisms from any species is referred to as variation. Genetic variety is mostly caused through mutation, although other processes like sexual reproduction and gene flow also play a role.

Environmental variation refers to environmental elements that can contribute to variances. Inherited variation refers to the variance that is genetically transmitted during reproduction from parents to children.

The variable of interest is a nominal variable, which means it merely belongs to categories and doesn't actually have any "numerical" values. Only the categories' names—1, 2, 3, and 4—have been utilized.

Only "sample proportions" can be determined for nominal variables, and the variance between sample proportions of various samples may be calculated and compared, but measurements of variation within a single sample (as is the case here) are useless for nominal variables.

Therefore, Option B is the correct answer.

When a point is reflected over the y-axis, the x-coordinate changes sign and the y-coordinate remains the same. So, the point R′′ will be (-4,-2)

With a 96% confidence level, we can be sure that the true population mean of SAR levels for cell phones falls between 0.918 and 1.130.where the critical value falls between 2.492.

We require the sample mean, population standard deviation, and sample size to determine the 96% confidence range for the population mean SAR level of cell phones. The standard error may be determined using a sample mean of 1.024, a population standard deviation of 0.337, and a sample size of 20.

After that, the confidence interval is determined as 1.024 (2.492) × (0.095) = (0.918, 1.130). This suggests that the genuine population mean of SAR values for cell phones falls between 0.918 and 1.130 with a 96% confidence level.

The formula for the 96% confidence interval for the population mean is given by:
Sample mean ± (Critical value) × (Standard error)

Where the critical value is 2.492 for a 96% confidence level and n = 20 degrees of freedom (sample size - 1). The standard error can be calculated as:

Standard error = Standard deviation / √n
Plugging in the given values:
Standard error = 0.337 / √20 = 0.095

The confidence interval is then:
1.024 ± (2.492) * (0.095) = (0.918, 1.130)

So, with a 96% confidence level, we can be sure that the true population mean of SAR levels for cell phones falls between 0.918 and 1.130.
