The chart below shows the distribution of weeds in a yard.

A circle graph titled Lawn weeds. The largest proportion is crab grass, then dandelion, then clover, then chickweed.

A lawn-care specialist chooses a random sample from the yard and determines the number of weeds in the sample. The results of the sample are shown in the table below.

Weed Type
Number
Dandelion
2
Clover
3
Crab Grass
2
Chickweed
2

Which explains whether or not this is a representative sample?
Yes, this is a representative sample because each type of weed is represented in the sample.
Yes, this is a representative sample because each type of weed is represented approximately the same number of times in the sample.
No, this is not a representative sample because each type of weed should be represented in proportion to the number of weeds actually present in the yard.
No, this is not a representative sample because each type of weed should be represented exactly the same number of times in the sample.

Answers

Answer: The answer is 9

Step-by-step explanation:

It is 9 because 3x3x3x3 is basically 9x9 and 9x9 is 81, so 81 is the numerator. Then we gat to the denominator, which is 3x3 and 3x3 is 9. So the new fraction you get is 81/9, which is basically 81 divided by 9. 81 divided by 9 is 9.

Answer:

9

Step-by-step explanation:

Subtract 2 from the 4 exponents on the numeral, then multiply that exponent, which would be 3×3=9 .

Find the solutions for a triangle with a = 16, c =12, and B = 63º.

a. A = 71.6°; C = 52.89; b =12.0

C. A = 68.6° C = 45.40; b=12.0

b. A = 71.6°; C = 45.40; b =15.0

d. A = 68.6°; C = 52.89; b=15.0

Answers

Answer:

b. A = 71.6°; C = 45.40°; b =15.0

Step-by-step explanation:

The missing values can be found with the help of the Law of Cosine and properties of triangles:

Side b (Law of Cosine)

[tex]b = \sqrt{a^{2}+c^{2}-2\cdot a \cdot c \cdot \cos B}[/tex]

[tex]b = \sqrt{16^{2}+12^{2}-2\cdot (16)\cdot (12) \cdot \cos 63^{\circ}}[/tex]

[tex]b \approx 15.022[/tex]

Angle A (Law of Cosine)

[tex]\cos A = -\frac{a^{2} - b^{2}-c^{2}}{2\cdot b \cdot c}[/tex]

[tex]\cos A = - \frac{16^{2}-15.022^{2}-12^{2}}{2\cdot (15.022)\cdot (12)}[/tex]

[tex]\cos A = 0.315[/tex]

[tex]A= \cos^{-1} 0.315[/tex]

[tex]A \approx 71.639^{\circ}[/tex]

Angle C (Sum of internal angles in triangles)

[tex]C = 180^{\circ} - 63^{\circ} - 71.639^{\circ}[/tex]

[tex]C = 45.361^{\circ}[/tex]

Hence, the right answer is B.

A. The total number of atoms cannot change during a reaction.
B. Chemical reactions cannot change reactants into products.
C. The reactants must have more atoms than the products.
D. A reaction has the same type of molecules before and after.

Answers

Answer: Choice A) the total number of atoms cannot change during a reaction

Matter cannot be created or destroyed. Instead, matter can be rearranged from one form to another. For example, boiling water turns the liquid into gas (steam) when it evaporates. The H2O molecules haven't been created or destroyed.

A) 6x + 20 < 29
B) 7x − 10 < 11
C) 14x + 10 < 37
D) 15x − 18 < 12

Answers

Answer: d.

Step-by-step explanation:

Add 18 to both sides.

15x<12+18

Simplify  12+18  to 30.

15x <30

Divide both sides by 15.

x < 15/30

Simplify 30/15 to 2.

x < 2

​​

The inequality 15x − 18 < 12 is true for x = 2

What is inequality?

A relationship between two expressions or values that are not equal to each other is called inequality.

Given that, are some inequalities, we need to find which of them is true for  x = 2

a) 6x + 20 < 29

Solving for x,

6x + 20 < 29

6x > 9

x > 3

b) 7x − 10 < 11

7x < 21

x < 3

c) 14x + 10 < 37

14x > 27

x > 27/14

d) 15x − 18 < 12

15x < 30

x < 2

Hence, the inequality 15x − 18 < 12 is true for x = 2

Find x?

The legs of a rectangle is what is regarded to as the adjacent and the opposite sides of the triangle.

Assuming the following

Adjacent = 6 and Opposite = √x

We can then solve the given example using Pythagoras theorem as foloes;

[tex]Hyp^2 = Opp^2 + Adj^2[/tex]

By substituting 10 for Hyp; 6 for Adj and √x for Opp

[tex]10^2 = 6^2 + (\sqrt{x})^2[/tex]

Step-by-step explanation:

Sam is transferring files from his friend's laptop into his flash drive. This is the formula for the size of the files on Sam's friends drive S (measured in megabytes) as a function of time t (measured in seconds): S(t)=5t+45

Use the above information to answer the following:
When the transfer began the drive had___ megabytes of files on it

Every 10 seconds, an additional___ megabytes are transferred into the drive.

Answers

Answer:

1. 45 megabytes

2. 50 megabytes

Step-by-step explanation:

Given

S(t) = 5t + 45

Required

Find S(t) when the transfer began

And find the additional transfer size at interval of 10 seconds

When the file transfer initially began, the value of t is 0.

Given that S(t)=5t+45.

Substitute 0 for t

S(0)=5 * 0 + 45

S(0) = 0 + 45

S(0) = 45.

Hence, the hard drive had 45 megabytes on it when the transfer started.

At every interval of 10 seconds. We take t to be 10, 20, 30...seconds

When t = 10

S(t)=5t+45 becomes

S(10) = 5(10) + 45

S(10) = 50 + 45

S(10) = 95 megabytes

When t = 20

S(t)=5t+45 becomes

S(20) = 5(20) + 45

S(20) = 100 + 45

S(20) = 145 megabytes

When t = 30

S(t)=5t+45 becomes

S(30) = 5(30) + 45

S(30) = 150 + 45

S(30) = 195 megabytes

Calculating the difference

Difference = S(30) - S(20) or S(20) - S(10)

Difference = 195 - 145 or 145 - 95

Difference = 50 or 50

See that the difference is the same.

So, at every 10 seconds interval, there's an additional 50 megabytes transferred
