Answer:
x < -3 is the solution for the given inequality - 8 > 8x + 16.
Step-by-step explanation:
Here, the given inequality is - 8 > 8x + 16
Now, we know if equal (positives) are added, subtracted multiplied or divided on both sides of in equality, the signs remain unchanged.
⇒ - 8 > 8x + 16 is equivalent to - 8 + 8 > 8x + 16 + 8
or, 0 > 8x + 24
⇔ -8x > 8x + 24 - 8x
⇔ -8 x > 24
or, (REVERSE SIGN as dividing by a a negative number)
or, x < -3
or, x < -3 is the solution for the given inequality.
Answer:
Step-by-step explanation:
given that on a six-question multiple-choice test there are five possible answers for each question, of which one is correct and four are incorrect
By mere guessing probability for choosing correct answer = p = 0.2
also each question is independent of the other
Hence if X is the number of correct questions then
X is binomial with p = 0.2 and n = 6
a) being correct on three questions,
=
(b) being correct on four questions,
=
(c) being correct on all six questions
=
<span>the formula is bh/2=area
b*(b-4)/2=16
(b^2-4b)/2=16
b^2-4b=32
b^2-4b-32=0
(b-8)(b+4)=0
b-8=0
b=8 feet for the base.
h=8-4=4 for the height.
proof
8*4/2=16
32/2=16
16=16</span>
