Answer:
170
Step-by-step explanation:
If you look at the other angle it says 20 and a whole circle would be 360 so subtract 360-130 then after that since the angle takes 2 part or however you may say that means u subtract 60 (20+20+20 thee open angle) this means you get 170 (i think im unsure but you can try)
Answer:
Question 1.
Question 2.
Explanation:
<u>Question 1. Boxed lunch.</u>
<em>The line of the random number table</em> shows these numbers:
There are <em>five different</em> types of <em>fruit</em>: <em>apple, banana, grapes, orange, and peach.</em>
Since there are 10 digits (0 - 9), in order for the random digits represent the event of picking some type of fruits, two different digits are assigned to each type of fruit.
It is stated that the digits <em>2</em> and <u>3</u> are assignated for <em>banana</em>.
Then, to use the random numbers to estimate <em>the probability that a boxed lunch will have a banana</em>, you must count the number of times a 2 or a 3 appears in the <em>line of the random number table</em>. That is why I bolded them.
There are in total 14 digits that are 2 or 3.
How many random numbers were generated: 50.
Hence, the probability is 14/50 = 7/25 = 0.28
<u>Question 2. Spinner</u>
The expected <em>number of times the spinner lands on green</em>, if you spin the spinner <em>90 times</em>, is equal to the probability times the number of times the spinner is spined.
![E(\overline X)=n\times P(X)=90\times4/15=24](https://tex.z-dn.net/?f=E%28%5Coverline%20X%29%3Dn%5Ctimes%20P%28X%29%3D90%5Ctimes4%2F15%3D24)
Answer:
-14/1
Step-by-step explanation:
10 x 2 = 20 6 x 2 = 12
20+12=32
the perimeter is 32ft
