X= 20 & Y= 70 in right-angled triangle .
What is right angle triangle?
- A right-angled triangle is a particular kind of triangle in which one of the angles is 90 degrees.
- The combined angles of the other two are 90 degrees. Perpendicular and the triangle's base make up the sides that the right angle is formed from.
- The longest of the three sides, known as the hypotenuse, is the third side.
2X + 140 = 180
2X = 40°
X = 20°
X + Y = 90°
Y = 70°

To solve the given equation, you would need to multiply t by both terms inside the parenthesis.
The equation would be D. (t*14) - (t*5)
The question was a bit confusing, and I have been searching for similar question. I found a picture similar to description about the dot plot as below:
1: 4 dots
2: 8 dots
3: 4 dots
4: 2 dots
5: 1 dot
Answer:
It never took more than 4 rolls to get an even number
Step-by-step explanation:
Total dots by even number: 8 + 2
Pr(even) = 10/19 = 1/1.9
In other word, for every 1.9 rolls (or 2 rolls), 1 will be even.
The data is skewed to the right since most of the rolls occupied by number 1,2 and 3.
And there is no prove that the event is being clustered, hence less likely to be cluster sampling
It doesn't take 3 rolls to get even number. 2 rolls needed to get even number.
The most correct answer should be 'it never take more than 4 rolls to get even number' since it only took 2 rolls to get an even number.
