Answers

Answer 1

Answer:

15

Step-by-step explanation:

Green is 3/5 of the set.

3/5 of 25 is 15.

Answer 2

Answer:

15 times

Step-by-step explanation:

Assuming that you are picking the marbles without replacement, the probability of picking a marble that is not blue is 3/5. This is because there are 3 green marbles and 2 blue marbles in the bag, so out of 5 possible outcomes, 3 of them are not blue.

To find the best prediction for the number of times you will pick a marble that is not blue in 25 trials, you can multiply the probability by the number of trials. This gives you 3/5 x 25 = 15. So, the best prediction is that you will pick a marble that is not blue 15 times out of 25.

Answer: 4x^3y^2(4 - 6xy^2)


Explanation:
To find the greatest common factor, or GCF, you have to find the number that all of the coefficients can be divided by and all the exponents can be subtracted by (and result in a non-negative exponent.)

In this case, the lowest exponent for x is 3, the lowest exponent for y is 2, and the GCF of -24 and 16 is 4.

Divide the whole equation (still meaning to subtract the exponents if you remember exponent rules) by 4x^3y^2. You then get 4 - 6xy^2.

Always remember to include the GCF on the outside.

So the answer is 4x^3y^2(4 - 6xy^2)
answer : 4x^3y^2 hope this helps for simply : ( 4 - 6xy^2 ) :))

Using Pythagoras Theorem

(Opposite^2)+(adjacent^2)=(hypotenuse^2)

:- (x+10)^2 + (x)^2 = 50^2
= (x^2)+20x+100+(x^2)=50^2
Collect like terms
(x^2)+(x^2)+20x+100=2500

Divide everything by 2 for easy calculation
x^2+10x-1200=0
Using Factorisation by grouping factors
(Factors that when multiplied together gives -1200 but when added gives +10:those factors are 40 and -30)
x^2 + 40x - 30x - 1200=0
(x^2 + 40x) -30x -1200= 0
Factorise
x(x+40) -30(x+40)=0
(x-30)(x+40)=0
For the answer to be 0 one of the factors must be 0 because anything multiplied by 0 is still 0
(x-30) =0 or (x+40)=0
x-30=0 or x+40=0
x=30 or x=-40

:- The values of x are 30 or -40

If you spin the spinner 4 times, what is the best prediction possible for the number of times it will not land on green?

NO WRONG ANSWERS PLEASE.

Answers

Answer: 2

Step-by-step explanation:

Probability of not green: 1/2

0.5*4=2

Answer:

2 times

Step-by-step explanation:

The spinner is divided into 2 sections one being yellow, one being green. This implies a 1/2 or 50% chance of landing on yellow.

Spinning it 4 times means a 2/4 chance of landing on yellow, which is equal to 1/2. This means that the prediction is that you will land on yellow 2 out of the 4 total times

If you spin the spinner 48 times, what is the best prediction possible for the number of times it will not land on yellow?

LOOK AT IMAGE

Answers

Answer:

20 times

Step-by-step explanation:

To determine the best prediction for the number of times the spinner will not land on yellow, we need to calculate the probability of the spinner not landing on yellow in a single spin and then multiply it by the total number of spins.

In this case, there are a total of 12 sectors on the spinner (4 greens + 7 yellows + 1 blue). The probability of the spinner not landing on yellow in a single spin is given by the sum of the probabilities of landing on green or blue:

P(not landing on yellow) = P(green) + P(blue) = 4/12 + 1/12 = 5/12.

Therefore, the probability of the spinner not landing on yellow in a single spin is 5/12.

To predict the number of times it will not land on yellow in 48 spins, we multiply the probability of not landing on yellow by the number of spins:

Prediction = (5/12) * 48 = 20.

Hence, the best prediction for the number of times the spinner will not land on yellow after 48 spins is 20.

It will land 20 times

Answer:

3x(2x -3)

Step-by-step explanation:

Simplifying the expression:

6x² - 9x

6x² = 2 * 3 * x * x

9x = 3 * 3 *x

Common factor = 3x

Take out the common factor from both the term.

6x² - 9x = (3x * 2x) - (3x * 3)

              = 3x * (2x - 3)

3x(2x-3) you have to take out the common terms and divide by them
