Given
The three sides are given 24, 30 and 18.
Explanation
To find the triangle is acute, obtuse or right triangle.
To determine whether the triangle is acute, right, or obtuse.add the squares of the two smaller sides, and compare the sum to the square of the largest side. Since this sum is greater, the triangle is acute.
A
If the sum of the squares of the two smaller sides is equal to the square of the largest side , then it is right triangle.
Now c.
Answer
Hence the sum of the squares of the two smaller sides is equal to the square of the largest side , then it is right triangle.
The correct option is A.
Answer:
C. z = 2.05
Step-by-step explanation:
We have to calculate the test statistic for a test for the diference between proportions.
The sample 1 (year 1995), of size n1=4276 has a proportion of p1=0.384.
The sample 2 (year 2010), of size n2=3908 has a proportion of p2=0.3621.
The difference between proportions is (p1-p2)=0.0219.
The pooled proportion, needed to calculate the standard error, is:
The estimated standard error of the difference between means is computed using the formula:
Then, we can calculate the z-statistic as:
z=2.05
Answer: 98268
Step-by-step explanation:
Given: In an international company,
Employees in one country = 22,700
If this is 23.1% of the total number of company's employees,
[
, replace 'of' by '×']
i.e. 23.1% of (total employees) = 22700
Hence, there are 98268 employees in total.
Answer:
25
Step-by-step explanation:
The first step in simplifying the expression of the square root of 50 involves finding factors of 50. This just means we are trying to find two whole numbers that, when multiplied, equal 50. Since 50 is an even number, 2 is going to be a factor, and so we can rewrite 50 as 2 times 25.
It is 23/100 just say it and then write it
