Explanation:
Design guidelines are sets of recommendations on how to apply design principles to provide a positive user experience. Designers use such guidelines to judge how to adopt principles such as intuitiveness, learnability, efficiency and consistency so they can create compelling designs and meet and exceed user needs.Given x2−3x+2=0
x2−2x−1x+2=0 (Resolving the expression)
x(x−2)−1(x−2)=0 (Taking common factors)
(x−2)(x−1)=0 (Taking common factors)
∴x−2=0 or x−1=0 (Equating each factor to zero)
∴x=2 or x=1
Let the sum of the observations be XX.
X10=5X10=5
⇒X=50⇒X=50
22 is added to each observation, which means total of
2×102×10 is added.
⇒X=50+20=70⇒X=50+20=70
The result is multiplied by 3
⇒3X=70⇒3X=70
⇒Y=70⇒Y=70
Y10=7010=7Y10=7010=7
Therefore, new mean is 77.
Please correct me, if I’m wrong

The values of the given series 3+4 = 19, 5+6 = 41, 1+3 = ??? is 7.
To find:
Give the Answer if 3+4 = 19, 5+6 = 41, 1+3 = ?
Solution:
Given: 3+4 = 19, 5+6 = 41, 1+3 = ???
3+ 4 = 19
Now, 3+4=7 \text { and } 3 \times 4=123+4=7 and 3×4=12 . If we add 7 + 12, we get 19.
Hence, addition of two given numbers i.e. on L.H.S. + multiplication of given two numbers i.e. on L.H.S. = required answer on R.H.S.
Likewise, 5 + 6 = 41
5+6=11 \text { and } 5 \times 6=305+6=11 and 5×6=30 . If we add 11 + 30, we get 41.
1+3 = ???
\bold{1+3=4 \text { and } 1 \times 3=3}1+3=4 and 1×3=3 . If we add 4 + 3, we get 7.
Hence, 1 + 3 = 7.
