I believe 5 marbles on the 6th line.

Line 1: 10

2: 10-1=9

3: 9-1=8

4; 8-1=7

5: 7-1=6

6: 6-1=5

For the pattern given, the number of marbles in the sixth line is 5.

Given that:

"Starting with 10, every consecutive line has a number one less than the previous line."

This is the pattern of the positions of the marbles.

The first line has 10 marbles.

The second line has 10 - 1 = 9 marbles.

The third line has 9 - 1 = 8 marbles.

The fourth line has 8 - 1 = 7 marbles

The fifth line has 7 - 1 = 6 marbles

The sixth line has 6 - 1 = 5 marbles.

The number of marbles in any line will be 10 - (n - 1) marbles for any nth line.

Hence the number of marbles is 5.

Answer: A; Linear, Strong

Step-by-step explanation: A linear scatterplot is normally when most of the dots on the scatterplot board are quite close to each other in a line. When it is strong it when most of the dots seem to form an actual line.

I hope this info helps!

A scatterplot categorized as "A: Linear, Strong" indicates a distinct and well-defined linear relationship, with closely clustered data points along the trend line, highlighting a robust association between the variables.

The correct answer is option A.

The scatterplot's visual characteristics provide insights into the nature of the relationship between two variables. In this case, when the answer is categorized as "A: Linear, Strong," it implies that the scatterplot predominantly exhibits a linear trend, suggesting a consistent and directional association between the variables. In a linear scatterplot, most data points align closely along a straight line, indicating a systematic relationship.

The term "strong" further emphasizes the degree of correlation or association between the variables. A strong linear scatterplot implies that the points are tightly clustered around the line, indicating a robust and noticeable relationship. The strength of the association is a reflection of how well the data points conform to the linear pattern, emphasizing the reliability of the trend observed.

In summary, when a scatterplot is described as "A: Linear, Strong," it signifies a clear and well-defined linear relationship between the variables, with data points forming a closely packed arrangement along the trend line.

QUESTION 1

We want to solve the linear equation,

–12 + 3b – 1 = –5 – b

Group similar terms:

3b+b=-5+1+12

Combine similar terms,

4b=8

Divide both sides by 4

b=2.

QUESTION 2

We want to find the equation of the given line that passes through

(-3,2) and (2,-1)

The equation is given by the formula:

[tex]y-y_1=m(x-x_1).[/tex]

We plug in the known values to obtain;

[tex]y + 1= - \frac{3}{5} (x- 2)[/tex]

[tex]y + 1= - \frac{3}{5} (x - 2)[/tex]

[tex]5y + 5 = - 3x + 6[/tex]

[tex]3x + 5y = 1[/tex]

Answer:

B. infinitely many solutions

Step-by-step explanation:

–2(–x + 9) = 2(x – 9)

Distribute the -2 on the left side. Distribute the 2 on the right side.

2x - 18 = 2x - 18

Add 18 to both sides.

2x = 2x

The equation means two times a number x is equal to two times the same number x. This is true for all numbers x. Every number is a solution of this equation.

Answer: B. infinitely many solutions

The answer is B.

Answer:

The y-intercept changes from (0, 3) to (0, -3)

Step-by-step explanation:

The y-intercept refers to the point where the graph of a function crosses or intersects with the y-axis. At this point, the value of x is usually 0.

Substitute x = 0 in both equations to determine how the y-intercept changes;

The original equation is given as y = 4x + 3,

when x = 0; y = 4(0) + 3 = 3

The y-intercept is thus (0, 3)

The new equation is given as y = 4x - 3

when x = 0; y = 4(0) - 3 = -3

The y-intercept is thus (0, -3)

Therefore, the y-intercept changes from (0, 3) to (0, -3)

Answer:

37ft³

Step-by-step explanation:

Volume of the fish tank = length × width × height = 5ft × 3ft × 3ft = 45ft³

Volume of the cubic stone = length × length × length = (2ft)³ = 8ft³

Volume of the water = volume of the fish tank - volume of the cubic stone

Step-by-step explanation:

207-18=189..then divide by 9

The problem involves subtracting Sara's remaining money from her initial amount to find the total spent on books, then dividing by the number of books, giving us that each book cost 21 dollars.

This is a basic algebra problem where we need to find the cost of each book. Sara initially has 207 dollars and after buying 9 books, she has 18 dollars left. Therefore, we can calculate the total spent on books by subtracting the final amount from the initial.

The calculation is: 207 dollars - 18 dollars = 189 dollars.

Now, to find the cost of each book, divide the total spent by the number of books. So, 189 dollars divided by 9 books results in 21 dollars per book.

Question 35

Any four vertices of a regular pentagon will form a parallelogram. This is because the internal angles and lengths are such that selecting any four vertices will always result in the formation of a closed, opposite sides being equal, and opposite angles being equal shape, which is a parallelogram.

Question 36

If two circles touch, the point of contact lies on a straight line. Hence, the correct answer is a straight line.

Question 37

The domain of the relation R where R = {(x,y): y = x + x ; x ≥ 0 and x < 9} will be as follows: we are given that y = x + x^2 and x ranges from 0 (inclusive) to 9 (exclusive). Thus, the possible values for x within these constraints are all integers from 0 to 8. Therefore, the correct domain is

{0, 1, 2, 3, 4, 5, 6, 7, 8} and correct option is d. None

Question 38

If Mary's share is Rs. 225 and it is divided between Mary and David in the ratio 3:2, we first find the portion that represents Mary’s share. Here, Mary’s share is 3 parts and David’s is 2 parts. Together, their shares add up to 5 parts. If 3 parts equate to Rs. 225, then 1 part is Rs. 75. The total amount of money, which is 5 parts, will be 5 * 75 = Rs. 375. Hence, the correct total is Rs. 375.

Question 39

The angle between the vectors 2î + 3ĵ + k and 2î - 3ĵ - k can be found using the dot product formula.

The dot product of A and B, A.B = |A| |B| cos θ. First, compute A.B:

Next, find |A| and |B|:

Therefore,

Taking the inverse cosine:

The approximate answer to the angle is around 116 degrees. However, because most multiple-choice sets would give their answers in radians, you would need to adjust accordingly. None of the provided answers exactly match this calculated result, therefore correct option is d. None

Answer:

To find the area of a rectangle multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area.

The area of a square is length times width:

Area = length x width

^^^This is the same for a rectangle too

The only difference is that the length of all the sides of a square are equal to each other, so to find the area of a square you are essentially multiplying on side with it self

Hence, Percentage of boys is calculated as:

[tex]Percent\ Boys=\dfrac{105}{160}\times 100\\\\i.e.\\\\Percent\ Boys=\dfrac{1050}{16}\\\\\\Percent\ Boys=65.625\\\\which\ is\ approximately\ equal\ to:\\\\Percent\ Boys=66\%[/tex]

B)

Number of students who like to surf=125

Hence,

Percent who like to surf is calculated as:

[tex]=\dfrac{125}{160}\times 100\\\\\\=\dfrac{1250}{16}\\\\=78.125\%[/tex]

C)

Number of boys=105

and number of boys who like to surf=80

Hence, the proportion of boys who like to surf is:

80/105

D)

Number of people who do not like to surf=35

Number of girls who do not like to surf=10

Hence,the proportion of girls who do not like to surf is:

              10/35

E)

Proportion of boys who like to surf=80/105=0.76190

and proportion of boys who like to surf= 45/55=0.8181

Hence, the proportion of girls who like to surf are more than those of boys who like to surf.

Answer:64

Step-by-step explanation:

In 1 pack there is 6 pencils cause you need to divide 36 by 6. In 3 packs there are 18 pencils because 6 pencils times 3 packs is 18 pencils!

Hope this helped!

Answer with step-by-step explanation:

We are given that there are 36 pencils in 6 packs and we are to find out how many pencils are there in one pack and three packs.

To find the number of pencils in one pack, we need to divide the number of pencils by the number of packs.

Number of pencils on 1 pack = 36/6 = 6 pencils

To find the number of pencils in 3 packs, we will multiply the number of pencils in one pack by 3.

Number of pencils in 3 packs = 6 * 3 = 18 pencils

Answer:

[tex]\left[\begin{array}{ccc}48&0&6\\4&-24&28\end{array}\right][/tex]

Step-by-step explanation:

4C implies that we multiply each element in C by the constant 4.

12*4 = 48

0*4 = 0

(3/2)*4 = 6

This will be the new elements on top

1*4 = 4

-6 * 4 = -24

7 * 4 = 28

This will be the new elements at the bottom. The required matrix 4C is thus;

[tex]\left[\begin{array}{ccc}48&0&6\\4&-24&28\end{array}\right][/tex]

Answer:

The required matrix is:

[tex]4C=\left[\begin{array}{ccc}48&0&6\\4&-24&28\end{array}\right][/tex]

Step-by-step explanation:

The matrix given is:

[tex]C=\left[\begin{array}{ccc}12&0&3/2\\1&-6&7\end{array}\right][/tex]

We need to find 4C which means we need to multiply the matrix C with 4. Every entry of matrix will be multiplied by 4.

[tex]4C=\left[\begin{array}{ccc}4*12&4*0&4*3/2\\4*1&4*-6&4*7\end{array}\right][/tex]

Solving:

[tex]4C=\left[\begin{array}{ccc}48&0&12/2\\4&-24&28\end{array}\right]\\4C=\left[\begin{array}{ccc}48&0&6\\4&-24&28\end{array}\right][/tex]
