Answer:
0.1302 or 13.02%
Step-by-step explanation:
So we know that 31% of the Dalmatians are blue eyed so that is 0.31. We also know that 42% of blue eyed Dalmatians are deaf so that is 0.42.
To find the probability of a blue eyed deaf Dalmatian we need 42% of 31%, so we need to do:
0.42 × 0.31 = 0.1302 or 13.02%
Answer:
Step-by-step explanation:
3n - 4 + 8 < 35 -9
3n < 35-9+4-8
3n < 22
n < 22/3
n < 7 1/3
$30 is 60% of $50.
100 % is the whole figure. Based on the problem, 100 % is separated into two parts, 60% and 40%
100% = 60% + 40%
To get the number where $30 is 60%. Let X be the 100% number.
First, divide all number by 100% to remove the percentage and get the whole number.
100%X = 30 + 40%X
X = 30 + 0.40X
X - 0.40X = 30
0.60X = 30
To get X, divide both sides by 0.60
X = 30 / 0.60
X = 50
To check: Substitute all X by 50.
X = 30 + 0.40X
50 = 30 + (0.40*50)
50 = 30 + 20
50 = 50 EQUAL. CORRECT.
