Make a number line and mark the points that represent the following values of x -1

Answer:

So here we have 3 adjacent angles, and add them all up they would equal a right angle as shown in the diagram.

POT is the right angle which can be seen by the square

POQ is the first angle

QOS is the second

SOT is the third

Now solve it.

We know that it has to be equal to 90 since thats the final reasoning.

4a + 20 + 3a - 10 + a = 90

Solve.

So you’d get 10.

If you want to elaborate then just say all adjacent angles has to add put o 90 since

[tex]Y=0.213x-352[/tex]  will represent this linear model shown in the data table.

Put the values of the x in the all given equations and then check the value of y if the value of y matches the given values in the option

So if we put the value x=1980 in the [tex]Y=0.213x-352[/tex]  then

[tex]Y=0.213(1980)-352[/tex]

[tex]Y=69.74[/tex]

These values are closest to 70.1 whereas other options do not satisfy the condition.

Thus [tex]Y=0.213x-352[/tex]  will represent this linear model shown in the data table.

Answer:

  $35.10

Step-by-step explanation:

The discount amount is subtracted from the original price to find the discounted price. That math can be done a couple of different ways.

  discount = discount rate × original price

  sale price = original price - discount

Or, these equations can be combined:

  sale price = original amount × (1 - discount rate)

__

Using the latter equation, we get ...

  sale price = $45.00 × (1 - 0.22) = $45.00 × 0.78 = $35.10

Leia will be paying $35.10 for the jacket.

Answer:

probably 7x + 5y

Step-by-step explanation:

Answer: 7x + 5y

Step-by-step explanation:  You combine the like terms so you would add 2x and 5x to get 7x-2+7y. Then you combine the other like terms so subtract -2y and 7y (You are subtracting because a negative and a positive is a negative).

The required equation 4x = - 9 is equivalent to the given equation 3 - 4x = 12. which is the correct answer would be option (C).

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

The equation is given in the question

⇒ 3 - 4x = 12

Subtraction by 3 on both sides of the above equation,

⇒ 3 - 3 - 4x = 12 - 3

⇒ 0  - 4x = 9

⇒ - 4x = 9

Multiply by (-1) on both sides of the above equation,

⇒  4x = - 9

Therefore, the required equation 4x = - 9 is equivalent to the given equation 3 - 4x = 12.

Hence, the correct answer would be an option (C).

Using the normal distribution and the central limit theorem, it is found that the probability the mean cost of the weddings is more than the mean cost of the showers is of 0.9665.

In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

For each sample, they are given by:

[tex]\mu_W = 82.3, s_W = \frac{18.2}{\sqrt{9}} = 6.0667[/tex]

[tex]\mu_S = 65, s_S = \frac{17.73}{\sqrt{6}} = 7.2382[/tex]

For the distribution of differences, we have that:

[tex]\mu = \mu_W - \mu_S = 82.3 - 65 = 17.3[/tex]

[tex]s = \sqrt{s_W^2 + s_S^2} = \sqrt{6.0667^2 + 7.2382^2} = 9.4444[/tex]

The probability the mean cost of the weddings is more than the mean cost of the showers is P(X > 0), that is, one subtracted by the p-value of Z when X = 0, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

By the Central Limit Theorem

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{0 - 17.3}{9.4444}[/tex]

[tex]Z = -1.83[/tex]

[tex]Z = -1.83[/tex] has a p-value of 0.0335.

1 - 0.0335 = 0.9665.

[tex]\frac{1}{3600}[/tex]

Step-by-step explanation:

400^2 = 160,000

5 2/6 = 32/6 = 16/3

6 70/30 = 250/30 = 25/3

16/3 * 25/3 = 400/9

400/9 / 160,000 = 1/3600

The product of the two terms [tex]\dfrac{4n}{(4n-4)} \times \dfrac{(n-1)}{(n+1)}[/tex] is [tex]\dfrac{n}{(n+1)}[/tex].

A fraction is a way to describe a part of a whole. such as the fraction 1/4 can be described as 0.25.

The product of the two fractions can be written as,

[tex]\dfrac{4n}{(4n-4)} \times \dfrac{(n-1)}{(n+1)}[/tex]

Taking 4 as the common term from both numerator and denominator of the first fraction, therefore,

[tex]\dfrac{4n}{4(n-1)} \times \dfrac{(n-1)}{(n+1)}\\\\=\dfrac{n}{(n-1)} \times \dfrac{(n-1)}{(n+1)}\\\\[/tex]

Now, cancelling the common factor from the numerator and the denominator, we will get,

[tex]=\dfrac{n}{(n-1)} \times \dfrac{(n-1)}{(n+1)}\\\\\\=\dfrac{n}{(n+1)}[/tex]

Hence, the product of the two terms [tex]\dfrac{4n}{(4n-4)} \times \dfrac{(n-1)}{(n+1)}[/tex] is [tex]\dfrac{n}{(n+1)}[/tex].

Step-by-step explanation:

In the quadrant (iv) terminal side of the angle fall. A quadrant is a region/section of a cartesian plane formed when the two axes intersect. It's used to figure out where a point is in a plane.

A horizontal line reached the x-axis and a vertical line reached the y-axis split a plane into four areas in the cartesian system. Quadrants refer to these four areas.

A quadrant is a region of a cartesian plane formed when the two axes intersect. It's used to figure out where a point is in a plane.

The angle in the standard position is measured at 92 degrees. We shall work in an anticlockwise fashion while evaluating positive angles.

Angles measuring 0° to 90° will be found in quadrant iv. Angles between 90° and 180° fall within quadrant iv. Because 92° is halfway between 90° and 180°,

Hence in the quadrant (iv) terminal side of the angle fall.

Answer:

3052 cm^3 (Answer C)

Step-by-step explanation:

The formula for the circumference of a circle of radius r is C = 2(pi)(r).  We know that C = 56.52 cm and want to find the model's radius:

                                       C                                                56.52 cm

Solving for r, we get ----------   so that in this case   r = ------------------  or

                                      2(pi)                                                 6.28

r = 9 cm.

The formula for the volume of a sphere of radius r is V = (4/3)(pi)(r^3), which here comes out to:

V = (4/3)(3.14)(9 cm)^3 = 3052 cm^3 (Answer C)

The statements about the power that is true include E. I, II, and III.

Power simply means the amount of energy that is transferred or converted per unit time.

It should be noted that an increase in sample size increases power and a test with a higher power is more likely to reject false null hypothesis.

Increasing sample size will make the hypothesis test more sensitive and thus more likely to reject the null hypothesis. Thus, it increases the power of the test.
