Answer:
y = 5
x = 10
Step-by-step explanation:
Remember your 30 60 90 triangle rules.
The 5√3 would equal x√3, so x would equal 5.
The x for the hypotenuse is 2x, so 2(5) is 10.
The y is the x for a 30 60 90 triangle, so y = 5.
Answer:
Im pretty sure its 11.6
Step-by-step explanation:
Answer:
The estimated mean number of rockets hits in the region is 533.
Step-by-step explanation:
We are given the following information,
Number of rocket hits | Observed number of regions
0 | 228
1 | 214
2 | 94
3 | 32
4 | 7
5 | 0
6 | 0
7 | 1
We are asked to estimate the mean number of rocket hits in the region.
The mean or expected value is given by

Therefore, the mean number of rockets hits in the region is 533.
Given:
The sequence is:
-15,-10,-4, 3, 11, ______
To find:
The next number.
Solution:
We have,
-15,-10,-4, 3, 11, ______
Here, the difference between two consecutive terms are:


Similarly,



It is clear that the difference difference between two consecutive terms is increasing by 1. So, the next difference must be (8+1)=9.
Let the next number be x. Then,



Therefore, the next number of the sequence is 20.
