A spinner is divided into five colored sections that are not of equal size: red, blue,
green, yellow, and purple. The spinner is spun several times, and the results are
recorded below:
Spinner Results
Color Frequency
Red
7.
Blue
13
Green 20
Yellow
14
Purple 9
Based on these results, express the probability that the next spin will land on blue or
green or purple as a decimal to the nearest hundredth.

Step-by-step explanation:

Q1 . (f+g)(x) = f(x) + g(x)

=4x-4 +2x^2 -3x

= 2x^2 + x -4

Q2. (f-g)(x) = f(x) - g(x)

= 2x^2−2 - (4x+1)

= 2x^2 -2 -4x -1

= 2x^2 - 4x -3

Q3. h(x)=3x−3 and g(x)=x^2+3

(h.g)(x) = h(x) × g(x)

= (3x-3) × (x^2 + 3)

=3x^3 -3x^2 + 9x -9

Q4.f(x)=x+4 and g(x)=x+6

(f/g)(x) = f(x) ÷ g(x)

= x+4 / x+6

the domain restriction is x>-6

x<-6

x doesn't equal (-6)

If the two function f(x) and g(x) are to be combined, use basic arithmetic rules,

(f + g)(x) = f(x) + g(x)

(f - g)(x) = f(x) - g(x)

[tex](\frac{f}{g})(x)=\frac{f(x)}{g(x)}[/tex]

(f . g)(x) = f(x) × g(x)

Question 1

f(x) = 4x - 4 and g(x) = 2x² - 3x

[tex](f+g)(x)=f(x)+g(x)[/tex]

Therefore, [tex](f+g)(x)=(4x-4)+(2x^2-3x)[/tex]

                                   [tex]=2x^2+x-4[/tex]

Question 2

f(x) = 2x² - 2 and g(x) = 4x + 1

Since, (f - g)(x) = f(x) - g(x)

Therefore, (f - g)(x) = (2x² - 2) - (4x + 1)

                               = 2x² - 2 - 4x - 1

                               = 2x² - 4x - 3

Question 3

h(x) = 3x - 3 and g(x) = x² + 3

Since, (h - g)(x) = h(x) - g(x)

Therefore, (h - g)(x) = (3x - 3) - (x² + 3)

                                = 3x - 3 - x² - 3

                                = -x² + 3x - 6

Question 4

F(x) = x + 4 and g(x) = x + 6

Since, [tex](\frac{f}{g})(x)=\frac{f(x)}{g(x)}[/tex]

Therefore, [tex](\frac{f}{g})(x)=\frac{x+4}{x+6}[/tex]

Answer:

C

Step-by-step explanation:

Answer:

c.

Step-by-step explanation:

Starting with the multiplications, first the multiply matrix A by -4, so we multiply every value in the matrix by -4 and we get

16 16 -4

-4 -16 -28

-8 -12 -12

Then we do the next multiplication which is 8 by matrix B, so once again we multiply every value in the B matrix by 8

16 72 -72

64 64 -16

32 80 8

Now that we did both multiplications, just need to sum the results, so we sum each value of matrix A with the value on the matrix B that's on the same spot

16 + 16 16 + 72 -4 + (-72)

-4 + 64 -16 + 64 -28 + (-16)

-8 + 32 -12 + 80 -12 + 8

And the final result is

32 88 -76

60 48 -44

24 68 -4

So it's option c

➠ Subtract 2 from both sides:-

[tex]2-\frac{1}{8}y-2=11+\frac{7}{8}y-2[/tex]

[tex]-\frac{1}{8}y=\frac{7}{8}y+9[/tex]

➠ Subtract 7/8y  from both sides:-

Answer:

0.737 rounded to nearest hundredth =

0.74

0.737 rounded to nearest tenth =

0.7

The number before any decimal place below 5 will stay the same.

Answer:

Nearest hundreth 0.74

Nearest tenth 0.7

Step-by-step explanation:

If the number to the right of the place value is larger, then that number will go up by 1. If the number is lower, then the place value will stay the same, and the entier number will be shortened.

So 0.737 to the nearest hundreth becomes 0.74

And 0.737 to the nearest tenth becomes 0.7

Answer:

i really dont know maybe 6

Step-by-step explanation:

Answer:

MN = 11

Step-by-step explanation:

M___A___Z___N

MZ =MA+AZ

MZ = 5x + 3x -2 = 8x - 2

MZ = AN

8x - 2 = 6(2x-1)

8x - 2 = 12x - 6

12x - 8x = 6 -2

4x = 4

x =4/4

x =1

MA= 5x = 5(1) = 5

AZ = 3x-2 = 3(1) - 2 = 3 -2= 1

MZ = 8x -2 = 8(1)-2= 8-2=6

AN = 12x - 6 = 12(1)-6 = 12 - 6 = 6

MN = MA + AN = 5 + 6 = 11

Answer:

y = -26

Step-by-step explanation:

[y = 2 - 2x] + [y = -16 + 2(x - 3)^2​]

y = -16 + 2x - 6^2

y = -16 + 2x - 6^2 + 2 - 2x

y = (+2x - 2x) - 16 - 6^2 + 2

y = -16 - 6^2 + 2

y = -16 - 12 + 2

y = - 28 + 2

y = -26

Answer:

This ratio would be 12:1

Step-by-step explanation:

There's 12 gallons of water to 1 cup of cleaner.

Answer:

you would need 12 gallons of water.

Step-by-step explanation:

The ratio is 4 : 1/3. This means that for every 1/3 cups of cleaner, there is 4 gallons of water.

This in mind, 3 1/3 cups of cleaner would be 1/3 x 3.

Whatever you do to one side, you have to do to the other.

4 gallons x 3 = 12.

Answer:

after 6 years

Step-by-step explanation:

thats when the lines intersect, (6,300)

There will be equal enrollment in Spanish and French classes after 6 years from now.

The red line shows the number of students enrolled in French class each year from now and blue line shows the number of students enrolled in Spanish class each year from now.

The point of intersection of the lines is the point which lies in both the line.

So, it represents the point or time when there are same number of students enrolled in both French and Spanish classes.

From the graph, we can see that the two lines at a point [tex](6,300)[/tex]. The value on the [tex]x[/tex]-coordinate shows the years from now. So, we can say that there will be equal number of students enrolled in two classes after 6 years.
