8765.82 is s how many hours are in one year exactly
Answer:
1. 2.9
2. 51 inches
3. (if you can send a picture of the question, I can tell you an answer.
Step-by-step explanation:
for number 1:
You have to add the scores on the left and divide it by the total. What I did was multiply each number on the right with it's pair and added it up. I got 111. Afterwards, I totalled the number of students (I got 38) and divided the scores by the number of students to get 2.9.
for number 2:
You do the same thing as number one but instead of multiplying pairs, you add the heights. I got 255 and then divided it by 5 total heights. I got 51 inches.
for number 3: I didn't get the graph to tell you the answer but I can tell you what everything means.
Symmetric means that both sides of the graph are equal and if you fold the graph in half horizontally, you should get the same shape.
Gaps are where you see blanks in the graph where the data gets cut off and then has stats again.
Cluster is when a huge amount of data is gathered in one area.
Peak is where the data (x-axis) reaches it's highest point (highest y-axis point).
Good luck and please give me Brainliest if you liked my answer!
Short Answer: B
Remark
The area of any triangle is
A = 1/2 b * h
b = 7 3/4
h = 4 2/3
Step one
Convert all fractions to improper fractions.
7 3/4 = (28 + 3) / 4 = 31/ 4
4 2/3 = (12 + 2) / 3 = 14/3 Now multiply
Step Two
Multiply
Area = 1/2 * 31/4 * 14/3 Multiply the numerators together and then the denominators.
Area = (1 * 31 * 14) / (2 * 4 * 3) = 434 /24
Step 3
Convert this to a whole number + a fraction
Area = 18 + 0.08333333 You already have your answer. It is B because only B gives an answer of 18. But you can get the rest of
Let x = 0.083333333
100 x = 8.3333333333
<u>x = 0.0833333333 </u> Subtract
99 x = 8.25 Divide by 3 on both sides.
33 x = 2.75 Divide by 11
3x = 0.25
x = 0.25/3 Multiply top and bottom by 4
x = 1 / 12
The answer is 18 1/12.
Answer:
10
β
Step-by-step explanation:
We can find this two ways, first by seeing in the step after it, cosines are canceled out. Since you already have 10β on the next step, you can assume that (since only the cosines changed and the cosine next ot the blank was removed), the value is 10β.
You can also use double angle formulas from the previous step:
(sin(2β) = 2 sin(β) cos(β))and find that:
5 sin (2β) sin(β) = 5 * (2 sin(β) cos(β)) sin(β)) = (10 sin(β) sin(β)) cos(β) =
10β cos(β)
But since cos(β) is already present, we can see that the answer is 10β
