We know, the sum of all the angle in an triangle is 180,
So, We can calculate adjacent angle of angle 1,
Let, that adjacent angle = b
So, 34 + 103 + b = 180
b = 180 - 137
b = 43
Now, angle b forms linear pair with angle a, so their sum would be 180
a + b = 180
a + 43 = 180
a = 180 - 43
a = 137
In short, Your Answer would be Option C
Hope this helps!
3*2 probably I’m sorry if it’s wrong
"Given : a survey was conducted in a group of 100 students of a school. the ratio of students who like mathematics and computer is 3:5. if 30 of them like both subjects and 10 of them like none of them,
To Find : number of students who like: at most one subject.
Solution:
Mathematics = 3k
Computer = 5k
30 of them like both subjects
10 of them like none of them
Total = Math + Computer - Both + None
100 = 3k + 5k - 30 + 10
=> 120 = 8k
=> k = 15
Mathematics = 45
Computer = 75
Mathematics only = Mathematics - Both = 45 - 30 = 15
Computer only = Computer - Both =75 - 30 = 45
at most one subject = 100 - Both subjects 100 - 30 = 70
or none + computer only + Mathematics only = 10 + 45 + 15 = 70
70 Students like at most one subject"
Answer:
4)There is a 4% chance that there is no relationship between temperature and revenue.
Step-by-step explanation:
Given that the owner of an ice cream shop wants to determine whether there is a relationship between ice cream sales and temperature. The owner collects data on temperature and sales for a random sample of 30 days and runs a regression to determine if there is a relationship between temperature (in degrees) and ice cream sales
A) The p value is the probability of rejecting null hypothesis when it is true.
In this case null hypothesis would have been there is no relationship between temperature and Sales.
The probability of concluding that there is relationship between temperature and sales when there is actually no real realtionship is only 0.04.
4)There is a 4% chance that there is no relationship between temperature and revenue.
is right answer
The answer is .5 meaning half (1/2) of the petals fell off.
