Answer:
X=24, Y=7
Step-by-step explanation:
We use the concept of similarity.
By observing the figure, we notice that the hypotenuse is 50, and the hypotenuse of the smaller triangle is 25.
That means the hypotenuse of the larger triangle is double the hypotenuse of the smaller triangle. Meaning, the other sides of the larger triangle would be double the smaller sides of the smaller triangle.
We already have the sides of the larger triangle, divide them by two to get x and y.
X = 48/2 = 24
Y = 14/2 = 7
Answer: 160 degrees
Step-by-step explanation:
(18-2)180 = 2880
2880/18 = 160
Answer:
- <em>B) 41 − 45; 46 − 50; 51 − 55; 56 − 60 </em>
Explanation:
When you build a <em>histogram </em>the intervals must be of the same size. About 4 to 8 intervals is good but it also depends on the number of data and the range of those data.
Option D has only two intervals. That is too few. Thus, this is discarded. Three intervals also seems few. Thus, option C, is not good.
The option A shows intervals of different size:
- 46 - 41 = 4
- 49 - 46 = 3
- 52 - 49 = 3
- 56 - 53 = 3
Thus, this is not good either.
The optio B seems good:
Interval Frequency
- 45 - 41 = 4 3
- 50 - 46 = 4 4
- 55 - 51 = 4 4
- 60 - 56 = 4 1
Hence, the correct answer is B) 41 − 45; 46 − 50; 51 − 55; 56 − 60
The answer to the question
Answer:
If in a company, 55% of workers are men, then,
100%-55%=45% in the company aren't men.
If x be the total number of workers in the company, then
45% of x=those who aren't men
45/100*x=1305
x=2900
Therefore, the total number of workers is 2900.
