Answer:

  B = 38°

Step-by-step explanation:

A straight angle is 180°. If your four angles total a straight angle, then ...

  60 +2x +3x +25 = 180

  95 = 5x . . . . . . subtract 85

  x = 19 . . . . . . divide by 5

  2x = 38 . . . . . angle B is 38°

omeli [17]

No, this is not an accurate predictor because angie is not representative of the population in the algebra test.

Here,

Angie, a student in an advanced statistics course, was given an algebra test and she scored 80%.

We have to find is this an accurate predictor.

What is Accurate predictor?

Accurate predictor describes whether the predicted values match the actual values of the target field within the incertitude due to statistical fluctuations and noise in the input data values.

Here,

Angie is the student of an  advanced statistics course but she gives the algebra test and scored 80%.

We know that the advanced statistics is the higher level of math so it is not an accurate predictor.

Because, An accurate predictor should be applied when the person is 100% confirmed to the related thing. So in the given situation, the student is not 100% confirm.

Hence,  this is not an accurate predictor because Angie is not representative of the population in the algebra test.

X^2 + 2x + 8 find the solution
Lina20 [59]

x^2 + 2x + 8

First, we'll try using the AC method.

(Because the degree of the quadratic is 2, there are two solutions.)

We cannot split the term using the AC method.

We'll instead use the quadratic formula.

\frac{-b +/- \sqrt{b^2 - 4ac} }{2a}

Plug in values.

(-2 +/- √4 - 32)/2

(-2 +/- √-28)/2

(-2 +/- i√28)/2

(-2 +/- 2i√7)/2

(-1 +/- i√7)

<h3>x = (-1 + i√7)</h3><h3>x = (-1 - i√7)</h3><h3>The two values of x are found.</h3>
