Answer:
relationship between base and perpendicular is given by tan angle
tan angle = perpendicular/base
tan angle =21/41
angle =tan -¹(21/41)=27
Answer:
for every cinnamon bun, 7 pennies were given to the orphanage.
x: amount given to orphanage
y: cinnamon bun
(hope you do well... i think this would work :/)
Range
The range measures the spread of the dataset by calculating the difference between the largest and the smallest element. In your case, marks range from 6 to 10, so the range is 10-6=4.
How many students
The frequency tells you how many students got each mark. So, we know that 5 students got a mark of 6, 4 students got a mark of 7, 7 students got a mark of 8, 10 students got a mark of 9, 4 students got a mark of 10.
This implies that, in total, we have
students.
Mean
The mean is given by the sum of the marks, divided by the number of students. We already observed how many students got each mark, so the sum of all marks will be a weighted sum, where each mark counts once per student:
Now we divide this sum by the number of students to get
So, the average mark is about 8.
1 cubic meter = 100 cm * 100 cm * 100 cm = 1 x 10^6 cc
1 kilogram = 1,000 grams
13.6 g / cc
If we had a cubic meter of mercury, its mass would be (or it would "weigh") 13.6 * 1,000,000 = 13,600,000 grams or 13,600 kilograms.
And so its density would be 13,600 kg / cubic meter.
Answer:
(-6,8)
Step-by-step explanation:
We are given that
The solution of equation is (_,8).
We have to find the missing value in the solution to the equation.
To find the missing value we will substitute y=8 in equation
Substitute y=8
Hence, the solution of equation is (-6,8).
