12. You are simply only looking for the least number of parts that both rectangles can be divided too. Find the least common multiple of both 3 and 4:
Multiples of 3: 3, 6, 9, 12
Multiples of 4: 4, 8, 12
12 is your answer.

John bought the TV for . . . . $1,900
John sold the TV for . . . . . $750
John lost this much on the TV . . . (1,900 - 750) = $1,150
What fraction of the amount he paid did he lose ?
$1,150 / $1,900 = 0.6053 of the amount he paid never came back
What is this fraction as a percentage ?
0.6053 = 60.53 %
Rounded to one decimal place: <em>60.5 % </em>
John took a beating on that TV. I hope he got a lot of good use out of it while he had it.
Answer:
P(A) = 0.49
Step-by-step explanation:
Given:
A and B are mutually exclusive events.
P(B) = 0.03
P(A or B) = 0.52
If two events A and B are mutually exclusive events, then there are no elements common in both the events. So, the probability of their intersection is 0.
Now, as per probability addition theorem:
P(A or B) = P(A) + P(B) + P(A and B)
For mutually exclusive events, P(A and B) = 0. So,
P(A or B) = P(A) + P(B) + 0
P(A or B) = P(A) + P(B)
Plug in the given values and solve for P(A). This gives,
0.52 = P(A) + 0.03
P(A) = 0.52 - 0.03
P(A) = 0.49
Therefore, the probability of occurrence of event A is P(A) = 0.49.
Answer:
a=-10/9
Step-by-step explanation:
vertex=(0,10) (h,k)
y=a^2x+bx+c
y=c=10 when x=0
the x intercepts are (0,3) and (0,-3)
y=a (x-h)^2+k
y=a(x-0)+10
y=ax^2+10
find a at point (3,0)
y=a(3)^2+10
0=9a+10
9a=-10
a=-10/9
y=-10/9 x^2+10
check with points(-3,0)
0=-10(-3)^2/9+10
0=-90+90=0 correct
Answer: it's the last
