Answer:

x = -1.1

Step-by-step explanation:

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

15x - 24 = 5x - 35

15x - 5x = -35 + 24

10x = -11

x = -11/10

x = -1.1

What is the remainder when (3x3 â€"" 2x2 4x â€"" 3) is divided by (x2 3x 3)?.

melamori03 [73]

The remainder of the equation is $\rm 28x+30$ .

Given that,

When the equation $\rm 3x^3-2x^2+4x-3$ is divided by $\rm x^2+3x+3$ .

We have to find,

The remainder of the equation?

According to the question,

The equation $\rm 3x^3-2x^2+4x-3$ is divided by $\rm x^2+3x+3$ .

On the division of the polynomial, the remainder is,

$\dfrac{\rm 3x^3-2x^2+4x-3}{\rm x^2+3x+3}$

Factorize the equation to convert this into the simplest form,

$\rm 3x^3-2x^2+4x-3\\\\3x^3-11x^2+9x^2+9x+28x-33x-33+30\\\\Taking \ the \ common \ terms \ and \ simplify\ the\ equation\\\\3x^3+9x^2+9x+11x^2+33x-33+28x+30\\\\3x(x^2+3x+3) - 11(x^2+3x+3) + 28x+30\\\\(3x+11) (x^2+3x+3) +28x +30$

Now, the equation can be written as,

$\rm = \dfrac{(3x+11) (x^2+3x+3) +28x +30}{ x^2+3x+3}\\\\= \dfrac{(3x+11) (x^2+3x+3) }{ x^2+3x+3} + \dfrac{28x +30}{ x^2+3x+3}\\\\= (3x+11) + \dfrac{28x +30}{ x^2+3x+3}\\\\$

The relation between the divisor, remainder, and quotient is,

$\rm = Quotient + \dfrac{Remainder}{Divisor}$

On comparing with the equation,

The remainder becomes 28x +30.

Hence, The required remainder of the equation is $\rm 28x+30$ .

NEED HELP ASAP A survey was conducted with high school students in

Mekhanik [1.2K]

Question:

a. Twenty-three ninth graders and fifteen eleventh graders prefer math.

b. Fourteen eleventh graders prefer math and eight tenth graders prefer English.

c. Thirty-five twelfth graders prefer math and nine tenth graders prefer English.

d. Twenty-three ninth graders and thirty-five twelfth graders prefer math.

e. Eighteen tenth graders prefer English and fourteen eleventh graders prefer math.

Answer:

Therefore, the correct options are;

b. and d.

Step-by-step explanation:

Here we have a table with blank boxes and totals from which we can fill the boxes;

For the 12th graders, we have a total of 67 pupils with 32 preferring English, therefore the number of the 12th graders that prefer math is 67 - 32 = 35 pupils

Similarly for the 11th graders we have total pupils = 29 with 15 preferring English, therefore the number of the 11th graders that prefer math is 29 - 15 = 14 pupils

Also for the 10th graders we have total pupils = 26 with 18 preferring math, therefore the number of the 11th graders that prefer English is 26 - 18 = 8 pupils

Finally for the 9th graders, we have a total of 63 pupils with 40 preferring English, therefore the number of the 9th graders that prefer math is 63 - 40 = 23 pupils

From the above, the correct option is

AnnyKZ [126]

Answer:

Option C, D and E

Step-by-step explanation:

=> An experiment to determine probability will include a number of trials. (it includes a number of trials. It is done multiple times having multiple trials.)

=> A probability experiment will count the number of times an event occurs. (Probability tells us how many times an event can occur.)

=> Experimental probability can be written in the form of a ratio. (Experimental Probability = $\frac{NumberOfFavourableOutcomes}{TotalNo.OfOutcomes}$ )
