= 1
-------------------
1/4 * 1/8 * -1024
= 1 / ( -32)
= -1/32

9, I believe.
4(2)+2(1)^2-(1)^3 (^ just means to the power of "exponent")
8+2-1=9
For the second question the answer should be 50×6=300+50=350 letters for Matilda. And for Lorraine It would be 40×6=240+80=320
Answer:
it is a decay, it's value drops by 4%
Step-by-step explanation:
0.96 is less than 1 so it is a decay function.
1-0.96 = 0.04 so it drops at the rate of 4%
Answer:
0.375 is answer
Step-by-step explanation:
Given that the math teacher gave her students two tests. On the first test, 80% of the class passed the test. But only 30% of the class passed both tests.
Let A - the students pass I test
B = students pass second test
Then P(A) = 80%=0.8 and P(AB) = 30% =0.30
Required probability =probability that a student passes the second test, given that they passed the first one
= P(B/A) = P(AB)/P(A)
= 0.30/0.80
=3/8
=0.375
Right answer is 0.375
