I'll explain it simply for you
1st question
Of course you know phythagoras theorm
You even wrote it up there
It states that the sum of the square of the two sides of an equilateral triangle is equal to the square of the hypotenuse
Where C is the hypotenuse
*NOTE* :
HYPOTENUSE is the greatest side in a triangle!!
And that's where your mistake is!
So you should take the greatest side as C
So in Q3. 7, 24 and 26 are the given numbers
You'll make the smaller two numbers a and b and the greatest number C
Using the Formula you'll solve the left side first which is
Then the right side which is
And if both are equal then it is a right triangle otherwise it isn't!
Let
a=7
b=24
c=26
a^2 + b^2
7^2 + 24^2
49 + 576 = 625
GREAT, Now the right side
26^2 = 676
Since they aren't equal it isn't a right angled triangle...
Then let
a=7.5
b=10
c=12.5
7.5^2 + 10^2
= 56.25 + 100
= 156.25
12.5^2 = 156.25
They are EQUAL
Therefore it is a right triangle too

Answer:
0.3830,0.6170
Step-by-step explanation:
Given that a process for manufacturing an electronic component yields items of which 1% are defective.
n =100 and p = 0.01
Here X no of defectives is binomial since independence and two outcomes.
Approximation to normal would be
X is N(
X is N(1,0.995)
a) the probability that the process continues given the sampling plan described
=
(with continuity correction)
=
b) the probability that the process continues even if the process has gone bad (i.e., if the frequency of defective components has shifted to 5.0% defective)
1-0.3830
=0.6170
Based on the info u have given, i just guessing that its 7.2
I'm probably wrong though
Answer:
The answer is D.............
