A packet has 54 sheets of paper. Suraj uses 4/9of the sheets. How many sheets has he used?​

Answer:

No

Step-by-step explanation:

The general rule for picking sample from a population at random ensures that all members of the population have equal chances of being selected.

Therefore to select 5 samples in the range 1 - 25 from a population of integers from 1 - 1000.

Firstly, befure we start selecting our samples directly from the population since we are not interested in all integers, we seperatw the integers belonging to our target samples from the population first, the we select 5 samples out of the sepwratwd integers between 1 - 25. This ensures that all our 5 samples will have integers between 1 - 25 becausw integers 1 - 25 is the range we want our specs to be within and not between 1 - 100.

However, from the trial samples recorded none of the samples have integer between 1 - 25 ; jnecw, the samples must have been chosen directly from the entire population of 1 - 1000

Answer:

15/8  

Step-by-step explanation:

This is a fraction so when dividing fractions you can multiply by the reciprocal.

5/8*3/1= 5*3/8*1 = 15/8  

180° rotation of any point about the origin gives the value with an alternate sign thus it will be (2,-7).

A pair of numbers that employ the horizontal and vertical distinctions from the two reference axes to represent a point's placement on a coordinate plane.

Given a point let's say A(-2,7)

If we rotate any point on coordinate geometry by 180 degrees about the origin then the horizontal and vertical distinctions will remain the same but the sign will change as shown below.

A(-2,7) ← Second quadrent

A'(2,-7) → Fourth quadrant

Hence "180° rotation of any point about the origin gives the value with an alternate sign thus it will be (2,-7)".

Answer:

120 and 40

Step-by-step explanation:

Given

[tex]\angle 1 = 160[/tex]

[tex]\angle 2 = 80[/tex]

Rotation = 180 degrees

Translation = 40 units down

Required

A measure of the resulting angles

180 degrees rotation

Rotation only affects the positioning of angles and does not change the measure of the angles.

So, the measure of both angles remain unchanged.

40 units down translation

This will reduce the measure of both angles by 40 degrees.

So:

[tex]\angle 1 = 160 - 40 = 120[/tex]

[tex]\angle 2 = 80 - 40 = 40[/tex]

Answer:

The amount in table as positive negative numbers: -5, 4, -1, 3, -2.

The spinner lands on red the change to Lisa's amount of money is -$5.

Step-by-step explanation:

Consider the provided table.

Part(A)

The table list how much a player receives or pays for various.

Paying some money is represented by a negative sign while receiving money is represented by a positive sign.

For red they needs to pay $5 which can be written as -5.

For blue they received $4 which can be written as 4.

For yellow they needs to pay $1 which can be written as -1.

For green they received $3 which can be written as 3.

For orange they needs to pay $2 which can be written as -2.

So, the amount in table as positive negative numbers: -5, 4, -1, 3, -2.

Part(B)

Now, we need to describe the change to Lisa’s amount of money when the spinner  lands on red.

If spinner lands on red then she needs to pay $5.

Thus, if the spinner lands on red the change to Lisa's amount of money is -$5.

Exact values are follows:

sin A = 0.98

cos A = 0.20

tan A = 5

In mathematics, the trigonometric functions are real functions which relate an angle of a right-angled triangle to ratios of two side lengths.

In mathematics, the Pythagorean theorem, or Pythagoras' theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle.

Given,

a = 10, b = 2

Draw the figure using the given data

Apply Pythagorean theorem to find the third side or hypotenuse

[tex]c^{2}=a^{2} +b^{2}[/tex]

[tex]c^{2}=10^{2}+2^{2}\\c^{2}=100+4\\ c^{2}=104\\ c=\sqrt{104}[/tex]

c = 10.19 units

We know sin θ = Opposite side / Hypotenuse

Sin A = [tex]\frac{10}{10.19}[/tex]

sin A = 0.98

cos θ = Adjacent side / Hypotenuse

cos A = [tex]\frac{2}{10.19}[/tex]

cos A =0.20

tan θ = Opposite side / Adjacent side

tan A = [tex]\frac{10}{2}[/tex]

tan A  = 5

Hence, the Exact values are follows:

sin A = 0.98

cos A = 0.20

tan A = 5

Answer:

1 + (1+6) + (1+6+6) + (1+6+6+6) = 4 × n

Step-by-step explanation:

The computation of the next line in the sequence is shown below:

As we can see that there is an increase of 6 in the left side and on the right hand side there is an increase of one

So,

1 = 1 × n

1 + (1+6) = 2 × n

1 + (1+6) + (1+6+6) = 3 × n

So, the next line would be  

1 + (1+6) + (1+6+6) + (1+6+6+6) = 4 × n

i.e.

1 + 7 + 13 + 19 = 4 × 10

As 1 + 7 + 13 + 19 = 40

And 40 = 4 × 10

[tex] \overrightarrow a= \bigg(\frac{5}{\sqrt 34},\:\frac{3}{\sqrt 34}\bigg)[/tex]

We have to show that [tex] \overrightarrow a[/tex] is an unit vector.

To show this, we will find the modulus of [tex] \overrightarrow a[/tex] and if its value is 1, it will be a unit vector.

So,

[tex] | \overrightarrow a| = \sqrt{\bigg(\frac{5}{\sqrt 34} \bigg) ^{2}+\bigg(\frac{3}{\sqrt 34}\bigg)^{2} } \\ \\ | \overrightarrow a| = \sqrt{\frac{25}{ 34} +\frac{9}{ 34} } \\ \\ | \overrightarrow a| = \sqrt{\frac{25 + 9}{ 34} } \\ \\ | \overrightarrow a| = \sqrt{\frac{34}{ 34} } \\ \\ | \overrightarrow a| = \sqrt{1} \\ \\ | \overrightarrow a| = 1[/tex]

Thus, [tex] \overrightarrow a[/tex] is a unit vector.

Answer: C, 8.2 - 5.8n

The expression for the nth term will be 8.2 - 5.8n. Then the correct option is C.

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

The first five terms in a pattern of numbers are shown. 2.4, -3.4, -9.2, -15, -20.8. Then the equation is given as,

At x = 1, y is 2.4.

2.4 = m + c           ...1

At x = 2, y is -3.4.

-3.4 = 2m + c          ...2

From equations 1 and 2, then we have

m = -3.4 - 2.4

m = - 5.8

Then the value of 'c' is given s,

2.4 = -5.8 + c

c = 8.2

Then the equation is given as,

y = 8.2 - 5.8x

If the pattern continues. Then the expression for the nth term is given as,

y = 8.2 - 5.8n

The expression for the nth term will be 8.2 - 5.8n. Then the correct option is C.

Answer:

The result of the integral is:

[tex]\arcsin{(\frac{x}{3})} + C[/tex]

Step-by-step explanation:

We are given the following integral:

[tex]\int \frac{dx}{\sqrt{9-x^2}}[/tex]

Trigonometric substitution:

We have the term in the following format: [tex]a^2 - x^2[/tex], in which a = 3.

In this case, the substitution is given by:

[tex]x = a\sin{\theta}[/tex]

So

[tex]dx = a\cos{\theta}d\theta[/tex]

In this question:

[tex]a = 3[/tex]

[tex]x = 3\sin{\theta}[/tex]

[tex]dx = 3\cos{\theta}d\theta[/tex]

So

[tex]\int \frac{3\cos{\theta}d\theta}{\sqrt{9-(3\sin{\theta})^2}} = \int \frac{3\cos{\theta}d\theta}{\sqrt{9 - 9\sin^{2}{\theta}}} = \int \frac{3\cos{\theta}d\theta}{\sqrt{9(1 - \sin^{\theta})}}[/tex]

We have the following trigonometric identity:

[tex]\sin^{2}{\theta} + \cos^{2}{\theta} = 1[/tex]

So

[tex]1 - \sin^{2}{\theta} = \cos^{2}{\theta}[/tex]

Replacing into the integral:

[tex]\int \frac{3\cos{\theta}d\theta}{\sqrt{9(1 - \sin^{2}{\theta})}} = \int{\frac{3\cos{\theta}d\theta}{\sqrt{9\cos^{2}{\theta}}} = \int \frac{3\cos{\theta}d\theta}{3\cos{\theta}} = \int d\theta = \theta + C[/tex]

Coming back to x:

We have that:

[tex]x = 3\sin{\theta}[/tex]

So

[tex]\sin{\theta} = \frac{x}{3}[/tex]

Applying the arcsine(inverse sine) function to both sides, we get that:

[tex]\theta = \arcsin{(\frac{x}{3})}[/tex]

The result of the integral is:

[tex]\arcsin{(\frac{x}{3})} + C[/tex]
