Sum of two interior angles=exterior angle

\\ \rm\Rrightarrow 45+65=y

\\ \rm\Rrightarrow y=110

  • Linear pairs have sum 180

\\ \rm\Rrightarrow x+y=180

\\ \rm\Rrightarrow x+110=180

\\ \rm\Rrightarrow x=70

7.003 x 10 to the power of 4
pishuonlain [190]
In scientific notation, just move the decimal point over however many numbers are in the power. 

In 7.003 • 10^4, move the decimal point over 4 places to the right, (or left if it's negative) making it 70,030

34kurt

Answer:

The probability it will land on green every time is \frac{1}{27}.

Step-by-step explanation:

We are given that a spinner is used for which it is equally probable that the pointer will land on any one of six regions. Three of the regions are colored red, two are colored green, and one is colored yellow.

The pointer is spun three times.

<u>As we know that the probability of an event is described as;</u>

  Probability of an event =  \frac{\text{Favorable number of outcomes}}{\text{Total number of outcomes}}

Here, the favorable outcome is that the spinner will land on green every time.

So, the number of green regions = 2

Total number of regions = 3(red) + 2(green) + 1(yellow) = 6 regions

<em>Now, the probability it will land on green every time is given by;</em>

        Probability =  \frac{2}{6}\times \frac{2}{6}\times \frac{2}{6}

                           =  \frac{1}{3}\times \frac{1}{3}\times \frac{1}{3}

                           =  \frac{1}{27}

Hence, the probability it will land on green every time is \frac{1}{27}.
