Answer: the answer would be choice A
Step-by-step explanation: it passes through the origin making it a proportional relationship
Answer:
x = -7
Step-by-step explanation:
The whole line is 12
the whole line is also x + 14 and x + 12
so make them equal:
x+14 + x +12 = 12
2x + 26 = 12 now subtract 26 from both sides
2x = - 14 now divide both sides by 2
x = -7
Answer:
The sample proportion from the sample of 900 is more likely to be close to the true population proportion, p.

for the first one
Answer:
1. 40%
2. The theoretical probability is 3% greater than the experimental probability.
Step-by-step explanation:
We are informed that a number cube is rolled 20 times and the number 4 is rolled 8 times. The experimental probability of rolling a 4 is;
(the number of times a 4 was rolled)/(total number of rolls)
8/20 = 0.4
0.4*100 = 40%
The experimental probability of obtaining at least one tails, one or more tails, is represented in mathematical notation as;
P(HT or TH or TT)
The above events are mutually exclusive, thus;
P(HT or TH or TT) = P(HT) + P(TH) + P( TT)
= (22+34+16)/(28+22+34+16)
= 0.72 = 72%
On the other hand, the theoretical probability of obtaining at least one tails,
P(HT or TH or TT) = 3/4
= 75%
This is because there is at least one tail in 3 out of 4 possible outcomes.
Therefore, it is true to say that the theoretical probability is 3% greater than the experimental probability.
