Answer:

$\boxed{x=60}$

Step-by-step explanation:

The exterior angle theorem states that the exterior angle of a triangle is equal to the sum of the two opposite interior angles of the triangle.

$130=70+x$

Subtract 70 from both sides.

$130-70=70+x-70$

$60=x$

Answer:

x = 60°

Step-by-step explanation:

Exterior angle is equal to the sum of opposite interior angles

x + 70 = 130

Subtract 70 from both sides

x = 130 - 70

x = 60°

A fair die is rolled in a board game to determine how many spaces a player can move on their turn. It has one of the numbers 1,2

Jet001 [13]

Answer:

(a)6 (b)3 (c)0.5

Step-by-step explanation:

Given a fair die with the numbers 1,2,3,4,5, or 6 on each of its faces.

Event A is the event of rolling an even number

Event B is the event of rolling an odd number.

(a)The sample space for the outcomes in this experiment is {1,2,3,4,5,6}

There are 6 outcomes in the sample space.

n(S)=6

(b)

Event A is the event of rolling an even number

Sample space of A = {2,4,6}

There are 3 outcomes in event A.

n(A)=3

(c)The probability of event A

$P(A)=\dfrac{n(A)}{n(S)} =\dfrac{3}{6} =0.5$

P(A) =0.5 is the probability that you choose an even number.

2. Red light: Pedro drives the same route to work on Monday through Friday. His route includes one traffic light.

Nataly [62]

Answer:

So, the probability is P=0.018.

Step-by-step explanation:

We know that Pedro drives the same route to work on Monday through Friday.

We know that there is a 55% chance that the light will be red.

We get that p=55%=0.55.

We conclude that the probability of not being a red light:

q=1-p=1-0.55=0.45.

We can calculate the probability that from Monday to Friday when Pedro goes to work there will be no red light, as follows:

$P=q^5\\\\P=0.45^5\\\\P=0.018$

So, the probability is P=0.018.

The volume of the rectangular prism:

V = length × width × height

$60x^3+145x^2+70x=5x(12x^2+29x+14)=5x(12x^2+21x+8x+14)\\\\=5x[3x(4x+7)+2(4x+7)]=5x(4x+7)(3x+2)$

Answer: $A.\ 5x(4x+7)(3x+2)$
