Answer:
(-12, 12) D
Step-by-step explanation:
Substitute y = 12 into the first equation:-
12 = -3/4x + 3
-3/4 x = 12 - 3 = 9
x = 9 * -4/3
= -12
so the answer is (-12, 12)
Well we don't get the full picture
Answer:
(c)
Step-by-step explanation:
As given in the statement, we have:
Out of 4 games pieces, 1 is winner.
Probability to win =p=
Jeff has game pieces = n = sample size = 4
As we need to find the probability that he wins exactly 1 prize, we will use binomial probability here :
Evaluating at k=1, (k=1 as we need to find probability for exactly 1 prize won)
put n = 4, p =
P (X = 1) =
P =
Which is the probability that he wins exactly 1 prize and is option c.
Step-by-step explanation:
1) let number=a
six times a number=6a
Condition:
6a+4=22
2) eleven times a number=11a
Condition:
11a-5=50
3) 9 times a number=9a
Condition:
9a-7=-16

2 times 4.95 equals 9.9
16.56 times 6 equals 99.36
add it up and it’s 109.26
