Step-by-step explanation:

Answer:

It's easy.

Step-by-step explanation:

The square root of something is just the reverse of some squared.

For example, if you do 3 to the power of 2 (3^2) you get 9. now if you reverse that you would do square root. [tex]\sqrt{9}[/tex] would be 3. Think of it like multiplication and division. If you do 10*5 you get 50. All you have to do is reverse it after that  50/5 = 10. See.

The only difference it square(2) root and squared(2) are only with the number 2. Meaning you can't do 3 to the power of 3 (3^3) and expect to square root it to get the reverse. For example, 3 to the power of 3 (3^3) is 27. But the square root of 27 is NOT 3, it is 5.2

Answer:

  x = 7

Step-by-step explanation:

Corresponding segments are proportional.

  x/8 = 21/24

  x/8 = 7/8 . . . . reduce the fraction

  x = 7 . . . . . . . multiply by 8

We are given:

The line passes through the points (9,4) and (9,-5)

We know that:

Slope of a line = (change in y) / (change in x)

Finding the slope:

Change in x = final x - initial x

Change in x = 9 - 9 = 0

Slope of line = (change in y) / 0

because division by 0 is undefined:

Slope of the line is Undefined

We could've solved for the change in y but there's no reason to because no matter what's in the numerator, as long as the denominator is 0, the value is undefined

A percentage is a way to describe a part of a whole. The amount of the sales tax is $10.5.

A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.

To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.

Given the taxable amount of the sale is $150, while the Sales tax percentage is 7%. Therefore, the amount of sales tax is,

Amount of sales tax = 7% of $150 = 0.07 × 150 = $10.5

Hence, the amount of the sales tax is $10.5.

Step-by-step explanation:

4 behind him 8 infront 6 left from infront leaving 4 behind 2 infront

Answer:

Explanation:

x = the number of students in front of peter

y = the number of students behind peter

z = the number of students who left, for 3 < z < 9 ∴ z ∈ {4, 8}

system of equations:

x = 2y ⇒ y = x/2 (defining y with x)

2(x-z) = y (lets substitute y)

2(x-z) = x/2

2x-2z = x/2

2(2x-2z) = x

4x-4z = x

4x-x = 4z

3x = 4z

if z = 6 (i pluged the numbers from 4 to 8)

then

3x = 4×6

3x = 24

x = 24/3

x = 8

∴ y = 4

8 students were in front of peter and 4 were behind him

6 left

now 2 students are in front of peter and 4 are behind him

8 is twice 4

8-6 = 2

4 is twice 2

Answer:

The team scored more free throws in fewer attempts (68 versus 66) and, furthermore, if the same amount of free throws had been attempted, the number of hits with that percentage would be 72. Therefore , it can be stated that the team significantly improved its free throw percentage.

Step-by-step explanation:

Given that in an early home game, an NBA team made 70.21 percent of their 94 free throw attempts, and in one of their last home games, the team had a free throw percentage equal to 76.4 percent out of 89 attempts, to determine if the team significantly improved its free throw percentage, the following calculation must be performed:

100 = 94

70.21 = X

70.21 x 94/100 = X

66 = X

100 = 89

76.4 = X

76.4 x 89/100 = X

68 = X

100 = 94

76.4 = X

76.4 x 94/100 = X

72 = X

Therefore, at first glance, the team scored more free throws in fewer attempts (68 versus 66) and, furthermore, if the same amount of free throws had been attempted, the number of hits with that percentage would be 72. Therefore , it can be stated that the team significantly improved its free throw percentage.

Answer:

The test statistic is [tex]z = 1.25[/tex]

Step-by-step explanation:

We are interested in determining whether or not the proportion of the student who experience anxiety during the exam is significantly more than 80%.

At the null hypothesis, we test if the proportion is 80%, that is:

[tex]H_0: p = 0.8[/tex]

At the alternate hypothesis, we test if the proportion is more than 80%, that is:

[tex]H_a: p > 0.8[/tex]

The test statistic is:

[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.

80% is tested at the null hypothesis:

This means that [tex]\mu = 0.8, \sigma = \sqrt{0.2*0.8} = 0.4[/tex]

A random sample of 100 students was taken. Eighty-five of the student in the sample experienced anxiety during the exam.

This means that [tex]n = 100, X = \frac{85}{100} = 0.85[/tex]

The test statistic is

[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

[tex]z = \frac{0.85 - 0.8}{\frac{0.4}{\sqrt{10}}}[/tex]

[tex]z = 1.25[/tex]

The test statistic is [tex]z = 1.25[/tex]

Answer:

I guess, you are asking how much two shirts are costing now.

the answer is $66

Step-by-step explanation:

sales tax is always calculated from the actual sales price (and never from a list price or so).

so, the discount is 50%.

=> a shirt now costs only $30 (instead of $60).

50/100*60 = $30

now, sales tax is calculated from these $30.

=> 10% of $30 is $3

10/100*30 = $3

therefore, a single shirt costs now $30+$3 = $33 incl. sales tax.

two shirts cost therefore 2 * $33 = $66

Answer:

a) The expression for the change in angular position is [tex]\theta = 5\cdot t[/tex].

b) The expression for the height of Ryan regarding the center of the Ferris wheel is [tex]H(t) = 40\cdot \sin (5\cdot t)[/tex].

c) The expression for the height of Ryan above the ground is [tex]H(t) = 40\cdot \sin (5\cdot t) + 47[/tex].

Step-by-step explanation:

The statement is incomplete. Complete form is introduced below:

Kyle boards a Ferris wheel at the 3-o'clock position and rides the Ferris wheel for multiple revolutions. The Ferris wheel rotates at a constant angular speed of 5 radians per minute and has a radius of 40 feet. The center of the Ferris wheel is 47 feet above the ground. Let t represent the number of minutes since the Ferris wheel stated rotating.

a) Write an expression (in terms of t) to represent the varying number of radians [tex]\theta[/tex] Ryan has swept out since the ride started.

b) Write an expression (in terms of t) to represent Ryan's height (in feet) above the center of the Ferris wheel.

c) Write an expression (in terms of t) to represent Ryan's height (in feet) above the ground.

a) Let suppose that Ferris wheel rotates counterclockwise. As the Ferris wheel rotates at constant rate, this kinematic expression can be used to determine the change in angular position ([tex]\theta[/tex]), in radians:

[tex]\theta = \omega \cdot t[/tex] (1)

Where:

[tex]\omega[/tex] - Angular velocity, in radians per minute.

[tex]t[/tex] - Time, in second.

If we know that [tex]\omega = 5\,\frac{rad}{min}[/tex], then the expression for the change in angular position is [tex]\theta = 5\cdot t[/tex].

b) Geometrically speaking, Ryan's height with respect to the center of the Ferris wheel is described by the following formula:

[tex]H(t) = r \cdot \sin (\omega\cdot t)[/tex] (2)

Where:

[tex]r[/tex] - Radius of the Ferris wheel, in feet.

[tex]H(t)[/tex] - Height of Ryan with respect to the center of the Ferris wheel, in feet.

If we know that [tex]\omega = 5\,\frac{rad}{min}[/tex] and [tex]r = 40\,ft[/tex], then the expression for the height of Ryan regarding the center of the Ferris wheel is [tex]H(t) = 40\cdot \sin (5\cdot t)[/tex].

c) We use the following geometric expression to model Ryan's height above the ground:

[tex]H(t) = r\cdot \sin (\omega\cdot t) +h_{o}[/tex] (3)

Where [tex]h_{o}[/tex] is the height of the center of the Ferris wheel above the ground, in feet.

If we know that [tex]h_{o} = 47\,ft[/tex], [tex]\omega = 5\,\frac{rad}{min}[/tex] and [tex]r = 40\,ft[/tex], then the expression for the height of Ryan above the ground is [tex]H(t) = 40\cdot \sin (5\cdot t) + 47[/tex].

Step-by-step explanation:

Please see the attached picture for the full solution.

First find the area of one side.

The area of the side of a cube is s^2 where s is the length if one edge.

The edge length is given as 2/3, so the area of a side is 2/3^2 which is equal to 2/3 x 2/3 = 4/9 square units.

A cube has 6 sides so now to find the surface area of the cube multiply the area of one side by 6 sides:

4/9 square units x 6 = (4 x6)/9 = 24/9 which can be rewritten as 2 2/3 square units

The answer is 2 2/3 units^2
