91

Step-by-step explanation:

10x11=110-20=90+1 = 91

Hope this helps plz hit the crown ;D

The answer is 91.

Step-by-step explanation:

(10 x 11) - 20 + 1

The first step would be to do the parentheses which would give you 110.

110 - 20 + 1

Next you can subtract 20 from 110 which would give you 90.

90 + 1

The final step would be to add

answer = 91

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
