Well since we’re given 2 angles, 62 and 58, we have enough information to solve the problem.
Since any triangles angles always add up to 180 degrees, we can simply add up 62 and 58 then subtract from 180.
62
+58
———
120
Now to find the last angle of the triangle you have to subtract 120 from 180 which is 60 degrees. This means x = 60.
However we’re not done, with this 60 we can now calculate y. Since the line is a 180 angle line! We can just subtract 60 from 180 which gives us 120.
The angle of y is 120
Answer: 160.4040
Step-by-step explanation:
Here , the claim is "The standard deviation of pulse rates of adult males is more than 11 bpm." , i.e. 
We use Chi-square test statistic for the test statistic to test the standard deviations :
, where s= sample standard deviation , 
= population standard deviations and n = sample size.
As per given , n=153 , s= 11.3
Then, Required test statistic will be :
Hence, the value of the test statistic. = 160.4040
Answer:
Number of Flowering Plants = 30
Number of vegetable plants = 20
Step-by-step explanation:
Im assuming the question is asking for the number of vegetables and number of flowers.
We need to convert 60% and 40% to decimal. The process is dividing by 100. Hence,
60% = 60/100 = 0.6
and
40% = 40/100 = 0.4
We multiply these with the total number to get number of vegetable and flowering plants.
So,
Number of Flowering Plants = 0.6 * 50 = 30
Number of vegetable plants = 0.4 * 50 = 20
Answer:
180 pages
Step-by-step explanation:
First you find the slope of the line assuming this is linear. it's just the Rise over Run. so go up 4 over 2 which means the slope is going up two. so do 90 times 2 which is 180. That means Jeff read 180 pages.
