I need help with this problem plz

Answer:

x = 18

Step-by-step explanation:

1. Let's solve for x, using the supplementary angles theorem, this way:

∠ C = 180 - 7x + 2 because they are supplementary angles. And these angles add up to 180 degrees.

∠ D = 180 - 9x + 31 because they are supplementary angles. And these angles add up to 180 degrees.

∠ E = 180 - 4x - 33 because they are supplementary angles. And these angles add up to 180 degrees.

Now, let's recall that the interior angles of a triangle add up to 180 degrees. Thus:

∠ C + ∠ D + ∠ E = 180 °

Replacing with the real values for solving for x:

180 - 9x + 31 + 180 - 4x - 33 + 180 - 7x + 2 = 180

- 20 x + 540 = 180

- 20 x = 180 - 540 (Subtracting 540 to both sides)

- 20 x = - 360

x = 18 (Dividing by - 20)

Proving that x = 18 is correct

180 - 9x + 31 + 180 - 4x - 33 + 180 - 7x + 2 = 180

180 - 9 (18) + 31 + 180 - 4 (18) - 33 + 180 - 7 (18) + 2 = 180

180 - 162 + 31 + 180 - 72 - 33 + 180 - 126 + 2 = 180

573 - 393 = 180

180 = 180

We proved that x = 18 is correct

Which terms could be used as the first term of the expression below to create a polynomial with a degree of 5 written in standar

Sladkaya [172]

Answer:

Option 2 - $-4x^3y^2$

Option 5 - $5x^4y$

Step-by-step explanation:

To find : Which terms could be used as the first term of the expression below to create a polynomial with a degree of 5 written in standard form?

Solution :

The polynomial with a degree of 5 means the polynomial of highest power must be 5.

Now, we check one by one,

1) $2x^2y^2-3xy^3$ - the highest degree is 4

2) $-4x^3y^2$ - the highest degree is 5

3) $x^3$ - the highest degree is 3

4) $8.4x^4y^2$ - the highest degree is 6

5) $5x^4y$ - the highest degree is 5

6) $-xy^3$ - the highest degree is 4

Therefore, In the above options- option 2 and 5 has the highest degree 5 which means they both have a polynomial with a degree of 5.

When we reject the null and the null is true, we have a made a _________ __________.

nydimaria [60]

When we reject the null and the null is true, we have a made a type I error

The null hypothesis in statistics states that there is no difference between groups or no relationship between variables. It is one of two mutually exclusive hypotheses about a population in a hypothesis test.

null hypothesis is denoted as H₀

Reject the null hypothesis when the p-value is less than or equal to your significance level. Your sample data favor the alternative hypothesis, which suggests that the effect exists in the population. When you can reject the null hypothesis, your results are statistically significant.

when the p-value is greater than your significance level, you fail to reject the null hypothesis.

Sometimes , we reject our null hypothesis even when its true

there we made a type I error in hypothesis
