Answer:

$\bf x=7^o$

Step-by-step explanation:

When two parallel lines are crossed by a transversal, co-interior angles They are called co-interior angles. The sum of the two angles on the same side of the transversal is always 180°.

$\bf 120^o+7x+11=180^o$

$\bf 7x+120+11=180$

$\bf 7x+131-131=180-131$

$\bf 7x=49$

$\bf \cfrac{7x}{7}=\cfrac{49}{7}$

$\bf x=7^o$

Answer:

x = 7

Step-by-step explanation:

corresponding interior angles are the angles which are formed in matching corners or corresponding corners with the transversal when two parallel lines are intersected by any other line

one is an obtuse and one is an acute angle in which sum up to 180°

(120°) + (7x + 11) = 180°

120° + 7x + 11 = 180°

131° + 7x = 180°

131° - 131° + 7x = 180° - 131°

7x = 49°

7x/7 = 49°/7

x = 7°

plug x in to check:

7(7) + 11 = 49 + 11 = 60

Rabies is a viral disease of mammals transmitted through the bite of a rabid animal. The virus infects the central nervous syste

lisabon 2012 [21]

Answer:

(a) The value of <em>x</em> is 0.30.

(b) The probability that a reported case of rabies is not a raccoon is 0.45.

(c) The probability that a reported case of rabies is either a bat or a fox is 0.15.

Step-by-step explanation:

Denote the events as follows:

<em>R</em> = reported case of rabies is a raccoon

<em>F</em> = reported case of rabies is a fox

<em>B</em> = reported case of rabies is a bat

<em>O</em> = reported case of rabies is a some other animal.

The data provided is:

P (R) = 0.55

P (F) = 0.11

P (B) = 0.04

P (O) = <em>x</em>.

(a)

A property of a probability distribution is that the sum of all individual properties is 1.

That is, $\sum P(X)=1$

Compute the value of <em>x</em> as follows:

$\sum P(X)=1\\P(R)+P(F)+P(B)+P(O)=1\\0.55+0.11+0.04+x=1\\0.70+x=1\\x=1-0.70\\x=0.30$

Thus, the value of <em>x</em> is 0.30.

(b)

The probability of the complement of an event is the probability of its not happening.

$P(A^{c})=1-P(A)$

Compute the probability that a reported case of rabies is not a raccoon as follows:

$P(R^{c})=1-P(R)\\=1-0.55\\=0.45$

Thus, the probability that a reported case of rabies is not a raccoon is 0.45.

(c)

Compute the probability that a reported case of rabies is either a bat or a fox as follows:

$P(B\cup F)=P(B)+P(F)\\=0.11+0.04\\=0.15$

Thus, the probability that a reported case of rabies is either a bat or a fox is 0.15.

Using the unit circle find the exact value. CSC -30º =

AlexFokin [52]

Answer:

csc (- 30)° = - 2

Step-by-step explanation:

Using the trigonometric relationship

csc x = $\frac{1}{sinx}$ and the exact value sin30° = $\frac{1}{2}$

sin(- 30)° = - sin30° = - $\frac{1}{2}$ , thus

csc (- 30)° = $\frac{1}{-\frac{1}{2} }$ = - 2
