3(2c+d)-4(c-d)+d^2
c=1 , d=3
Use the substitution method
3(2*1+3)-4(1-3)+3^2
Multiply the brackets
3(2+3)-4+12+9
6+9-4+12+9
15-4+12+9
11+21
=32
Answer: 32
D. 160 you simplify the expression to get your answer.
Answer:
- (139/2)
Step-by-step explanation:
18 1/2 -2^3•(4 1/3 + 6 4/6)
= 37/2 - 8 .( 13/3 + 40/6)
= 37/2 - 8 x 11
=37/2 - 88
= - (139/2)
Answer:
21/41
Step-by-step explanation:
Find the total number of students
6+7+2+3+6+8+4+5=41
Then find the students that do not study chemistry
6+7+2+5 = 20
P( not study chemistry) = do not study chem)/total
=21/41
He has a 26% of getting a strike, which means he has a 74% chance of not getting a strike ( 100% - 26% = 74%).
Multiply the chance of not getting a strike by the number of attempts:
0.74 x 0.74 x 0.74 x 0.74 x 0.74 = 0.22
The answer is B) 0.22
The probability of making a free throw is 77%, the probability of not making one would be 23% ( 100% - 77% = 23%).
Add the probability of making the first one ( 0.77) by the probability of making the second one multiplied by the probability of missing the second one ( 0.77x 0.23)
0.77 + (0.77 x 0.23)
0.77 + 0.18 = 0.95
The answer is D) 95%
