Choose the polynomial that is written in standard form 7x^5+8x^8+27x





Don’t need the answer just couldn’t find the question lol so the answer is 3

Answers

Answer: Option d: -3*x^4*y + 2*x^2*y^2 + 5*y^3

Step-by-step explanation:

In standard form, the first term of the polynomial must be the term with the highest degree and on each subsequent term the degree decreases. In the case of two variables, the degree is equal to the sum of the exponents.

Then the correct option is d.

Where the degree of the first term is (4 + 1) = 5

The degree of the second term is (2 + 2) = 4

The degree of the third therm is 3.

We can see that the degree decreases as the term number increases, then the polynomial written in standard form is:

-3*x^4*y + 2*x^2*y^2 + 5*y^3

m∠R= 87°

Step-by-step explanation:

The angles in a polygon add up to (n-2)180

If you flip two coins 64 times, what is the best prediction possible for the number of times
both coins will land on heads?
I need help quick this is a math unit test and it’s not 32 !

Answers

Answer:

The best prediction possible for the number of times both coins will land on heads is 16.

Step-by-step explanation:

For each time the two coins are flipped, there are only two possible outcomes. Either they both land on heads, or they not. Coin flips are independent, which means that we use the binomial probability distribution to solve this question.

Binomial probability distribution

Probability of exactly x sucesses on n repeated trials, with p probability.

The expected value of the binomial distribution is:

[tex]E(X) = np[/tex]

On a trial, probability of two heads.

Each trial has two coins, each with 0.5 probability of landing on heads. So the probability of two heads on a trial is:

[tex]p = (0.5)^2 = 0.25[/tex]

64 times

This means that [tex]n = 64[/tex]

What is the best prediction possible for the number of times both coins will land on heads?

The expected value. So

[tex]E(X) = np = 64*0.25 = 16[/tex]

The best prediction possible for the number of times both coins will land on heads is 16.

What percent is represented by the shaded area?

Answers

Answer:

160%

Step-by-step explanation:

Because the first square (the one to the left) is shaded to the brim, it represents 100%.

The second square (the one to the right) is shaded only until the 6th row, we can say that it is shaded 6/10 rows, or 60%.

Lastly, add the percentages of the two squares => 100% + 60% = 160%

160%. One box is fully shaded and the other has 6 rows shaded. 100% + 60% =160%

Step-by-step explanation:

1) Replace f(x) with y: y = 19/x^3
2) Interchange x and y: x = 19/y^3
3) Solve this result for y: xy^3 = 19, or y^3 = 19/x, or

The inverse is y = ∛[19/x]
