All angles in a triangle should equal 180° so I'll give the different equations and solve them
17) 55+54+x+74=180
183+x=180
subtract 183 on both sides
-3°=x
18) 70+60+8x+2=180
132+8x=180
subtract 132 on both sides
48=8x
x=6°
those are the first two

Answer:
11.55% probability that the purchase was made with a mobile device and was from Amazon.
Step-by-step explanation:
We have these following probabilities:
21% probability that a Cyber Monday shopper used their mobile device to make a purchase.
55% probability that a purchase made with a mobile device is from Amazon.
What is the probability that the purchase was made with a mobile device and was from Amazon."
55% of 21%
So
P = 0.21*0.55 = 0.1155
11.55% probability that the purchase was made with a mobile device and was from Amazon.

Answer:
The average temperatures were:
- <u>New York City: 63</u>
- <u>San Francisco: 64</u>
Step-by-step explanation:
Remember that, the average is obtained in the form below:
- Average = The sum of all the values / the number of values.
In this case, the number of values is 12 because are the number of months in the year. The sum of values is shown below for each case:
- <u>Average temperature in New York City = (39 + 42 + 50 + 61 + 71 + 81 + 85 + 84 + 76 + 65 + 55 + 47) / 12 = 63.
</u>
- <u>Average temperature in San Francisco = (57 + 60 + 62 + 63 + 64 + 67 + 67 + 68 + 70 + 69 + 63 + 58) / 12 = 64.</u>
I don't add units because the table doesn't specify if they are Celsius, Fahrenheit, or others.
