Answer:
y = root under 24 (evaluate it if necessary)
or y = 2 root 6
Step-by-step explanation:
Let the reference angle be x
for the triangle in left,
b = 6-4 = 2
Now,
taking x as refrence angle,
cosx = b/h
or, cosx = 2/h
again,
for the bigger triangle,
taking x as reference angle,
cosx = b/h
or, cosx = b/6
As we can see base of bigger triangle is equal to hypotenuse of triangle at the left,
Let's suppose its a
so, cosx = a/6 = 2/a
now,
a/6 = 2/a
or, a² = 12
now,
for bigger triangle, using pythagoras theorem,
h² = p²+b²
or, 6² = y² + a²
or, 36 = y² + 12
or, y² = 24
so, y = root under 24
Answer:
(C) Q1: 55.5 Q2: 110 Q3: 295
Step-by-step explanation:
Given the dataset:
There are 25 items in the dataset.
To find Q2, We divide it into two equal parts and consider the middle term
Therefore: Q2 =110
Q1 = the median of the lower half of the data set.
Q3 = is the median of the upper half of the data set.
In the lower half of the data
Since there are even number of terms,
Median = (55+56)/2=55.5
Therefore: Q1=55.5
In the upper half of the data
Since there are even number of terms,
Median = (239+351)/2=295
Therefore: Q3=295
Q1: 55.5, Q2: 110, Q3: 295
The correct option is C.
