Number of red marbles pulled = 8

Number of blue marbles pulled = 8

Total marbles pulled = 25

Relative Frequency = Total Frequency / Total number of data values

Relative Frequency of red marble = 8/25

                                                         = 32%

Relative Frequency of blue marble = 8/25

Answer:

Andre should stop at (-3 , 6.5)

Step-by-step explanation:

The change in x is from -15 to 25 which is 40 units. 40 x 3/10 = 12 which means Andre moves 12 units right starting from -15 so the x coordinate is -15+12 = -3

The change in y is from 2 to 17 which is 15 units. 15 x 3/10 = 4.5 which means Andre moves 4.5 units up starting from 2 so the y coordinate is 2+4.5 = 6.5.

Answer: x=1

Step-by-step explanation:

4x+7=11

4x-7=11-7

4x=4

4/4=1

x=1

Answer:

First we add 7 on both sides

-7x+3y= -6.3

+7. +7

___________

then we simply

-7x + 7x= -1

bring down the 3y

-6.3+ 7x = 0.23

So, -1x+3y=0.7

Answer:

y = 10x + 60

Step-by-step explanation:

So, the chart coordinate should looks like this:

(1, 75)

(2, 70)

(3, 80)

(4, 95)

(4, 100)

And there is a line passing (0, 60) and (2, 80)

So we just need to find the y-intercept and the slope by the line:

Slope: [change in x over change in y] = 20 ÷ 2 = 10

y-intercept: [the value of y when x equal 0] = 60 (because the line passed through (0, 60) )

A:  \(-\frac{3}{8}\) b + \(\frac{15}{24}\)

B:  \(-\frac{1}{8}\)  (3b - 5)

Step-by-step explanation:

Part A

\(-\frac{1}{4}\) b + \(\frac{1}{12}\) -  \(\frac{1}{8}\) b + \(\frac{13}{24}\)

=  \(-\frac{1}{4}\) b -  \(\frac{1}{8}\) b + \(\frac{1}{12}\) + \(\frac{13}{24}\)

=  \(-\frac{2}{8}\) b -  \(\frac{1}{8}\) b + \(\frac{1}{12}\) + \(\frac{13}{24}\)

=  \(-\frac{3}{8}\) b + \(\frac{1}{12}\) + \(\frac{13}{24}\)

=  \(-\frac{3}{8}\) b + \(\frac{2}{24}\) + \(\frac{13}{24}\)

=  \(-\frac{3}{8}\) b + \(\frac{15}{24}\)

Answer:

5400 cubes can be fit into the prism.

Step-by-step explanation:

We are given the dimensions of prism as:

5 units by 5 units by 8 units i.e. 5 units×5 units×8 units.

Hence, the volume of the prism is given by:

Volume of prism=5×5×8=200 cubic units

Also the edge length of cube is given by= 1/3 unit.

Hence volume of 1 cube=

Hence volume of 1 cube= (1/27) cubic units.

Let 'n' cubes can be fitted into the prism.

Hence we have the relation as:

Volume of prism=n×Volume of 1 cube.

200=n×(1/27)

n=200×27

n=5400

Hence 5400 cubes can be fitted into the prism.

Answer:  iii. (5 x 3) x (5 x 3) x (8 x 3)

Explanation:

If we ignored the smaller cubes, then the prism itself has the volume of 5 x 5 x 8 cubic units.

Now consider the smaller cubes. We can fit 3 to each unit (because 3*(1/3) = 1). This means each dimension is tripled.

We go from 5 x 5 x 8 to (5 x 3) x (5 x 3) x (8 x 3)

Here are the pairs matched with their products:

- (-5)(4.2) matches with -21

- (-7)(-3) matches with 21

- (2.5)(-9) matches with -22.5

Pairs (4) and (5) do not have corresponding products in the given options.

Answer:

Step-by-step explanation:

To solve the congruence 5x ≡ 6 (mod 7), we need to find a value for x that satisfies the equation.

First, we'll find the multiplicative inverse of 5 modulo 7. The multiplicative inverse of a modulo m is a number x such that ax ≡ 1 (mod m). In this case, we need to find a number x such that 5x ≡ 1 (mod 7).

To find the multiplicative inverse, we can try different values of x and compute the result until we find one that satisfies the equation. Alternatively, we can use a more efficient method like the Extended Euclidean Algorithm.

Using the Extended Euclidean Algorithm, we find that the multiplicative inverse of 5 modulo 7 is 3, as 5 * 3 ≡ 1 (mod 7).

Now, we can multiply both sides of the congruence by the multiplicative inverse (3) to isolate x:

5x ≡ 6 (mod 7)

3 * 5x ≡ 3 * 6 (mod 7)

15x ≡ 18 (mod 7)

Reducing the coefficients:

1 * x ≡ 4 (mod 7)

Since x ≡ 4 (mod 7), the solution to the congruence 5x ≡ 6 (mod 7) is x ≡ 4 (mod 7). This means that x can be written as x = 4 + 7k, where k is any integer.

Answer:

The total area of the back classroom wall is (20ft x 12ft) = 240ft²

The paint coverage is usually rated by area coverage. For example, one gallon of paint is expected to cover 400 ft².

Assuming a gallon of paint will cover 400ft², she will need (240ft²/400ft²) = 0.6 gallon of paint to cover the entire wall.

Mrs. Jones will need 0.6 gallon of paint to paint the back classroom wall.

Step-by-step explanation:

just did this question on a quiz .

Answer:

24x² -19x-35= 0

24x² -(40-21)x -35= 0

24x²-40x+21x-35=0

8x(3x-5) +7(3x-5)=0

(3x-5) (8x+7)=0

(Ax-5)(2Bx+C) = (3x-5) (8x+7)

Comparing them,

A = 3

B = 4

C= 7

AB-3C = (3×4) - 3(7) = 12-21 = -9

We can factor out 8 from both terms:

32 + 40x = 8(4 + 5x)

Therefore, the expression is factored completely as 8(4 + 5x).

Answer:

8(4+5x)

Step-by-step explanation:

32 and 40 can both be divided by 8 leaving it with 4 and 5

so it'll be 8(4+5x)

Answer:

D is the right choice and no you cannot fit the pizza inside the box.

Step-by-step explanation:

D is the answer because to turn 2/3 into a decimal you would divide 2 by 3 and the answer you would get would be 0.66666666666...You would then add 12 to the answer and get 12.6666... Once you get this answer you would round it to the hundredths to get 12.67 but since that is not an option you could use D, 12.66 inches.

Answer:

I believe the answer is D.

keeping in mind that perpendicular lines have negative reciprocal slopes, let's check for the slope of the equation above

\(y=\stackrel{\stackrel{m}{\downarrow }}{\cfrac{1}{3}}x+16\qquad \impliedby \qquad \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array} \\\\[-0.35em] ~\dotfill\)

\(\stackrel{~\hspace{5em}\textit{perpendicular lines have \underline{negative reciprocal} slopes}~\hspace{5em}} {\stackrel{slope}{ \cfrac{1}{3}} ~\hfill \stackrel{reciprocal}{\cfrac{3}{1}} ~\hfill \stackrel{negative~reciprocal}{-\cfrac{3}{1} \implies -3}}\)

so we're really looking for the equation of a line whose slope is -3 and it passes through (-9 , 13)

\((\stackrel{x_1}{-9}~,~\stackrel{y_1}{13})\hspace{10em} \stackrel{slope}{m} ~=~ - 3 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{13}=\stackrel{m}{- 3}(x-\stackrel{x_1}{(-9)}) \implies y -13 = - 3 ( x +9) \\\\\\ y-13-3x-27\implies {\Large \begin{array}{llll} y=-3x-14 \end{array}}\)

Answer:

m = 1/3

m⊥ = -3

x1 = -9

y1 = 13

point slope: y-13 = -3(x+9)

slope intercept: y= -3x-14

Step-by-step explanation:

Equation given is in y=mx+b form, so I think m=1/3 (or whatever is right before the x cause it is little hard to see)

To find a perpendicular slope, you use the negative reciprocal of the given slope, so the perpendicular slope would be m=-3

x1 and y1 would be the given coordinates so -9 and 13 respectively

Finally plug in all this info into point slope form equation (y-y1 = m(x-x1)

Point slope would be: y-13 = -3(x+9)

Slope intercept would be: y= -3x-14

Hope this helps!
