Answer:

10 sides

Step-by-step explanation:

Since each interior angle measures 144

We say 180 -144 = 36

so inorder to find the number of sides

=360/36

=10(number of sides)

Answer:

Brainliest!

Step-by-step explanation:

Since the interior angle is 144 degree, each exterior angle is 180 - 144 = 36 degrees

number of sides = 360/36 = 10

The polygon is decagon with 10 sides

The vertex of this parabola at (-5,-2). When the c - value is -4 the y-value is 2 what is the coefficient of the squared express

Andre45 [30]

Answer:

Step-by-step explanation:

The vertex formula of a quadratic equation is:

●y= a(x-h)^2 +k

(h,k) are the coordinates of the vertex

Here: h = -5 and k= -2

y is 2 and x is -4

● 2 = a (-4-(-5))^2 + (-2)

● 2 = a (-4+5)^2 -2

● 2 = a *1^2 -2

● 2 = a -2

● 4 = a

At a certain university, 42% of the students are women and 18% of the students are engineering majors. Of the engineers, 22% are

m_a_m_a [10]

Answer:

The probability that the selected person is a woman engineering major is 0.0396.

Step-by-step explanation:

The proportion of students at the university who are women is 0.42.

The proportion of students at the university who are engineering majors is 0.18.

<em>P (E) = 0.18</em>

The proportion of engineering majors that are women is 0.22.

<em>P (W|E) = 0.22</em>

The proportion of students at the university that are woman and engineering major is:

$P (W|E)=\frac{P(W\cap E)}{P(E)} \\P(W\cap E)=P(W|E)\times P(E)\\= 0.18\times0.22\\=0.0396$

Thus, the probability that the selected person is a woman engineering major is 0.0396.
