Step-by-step explanation:
Given that,
The mass of a patient = 70 kg
A 70kg patient has approximately 8 pints of blood.
The patient donates 470mL of blood.
We know that,
1 pint = 568 mL
8 pints = 4544 mL
Required fraction,
So, the required fraction is approximately .
Answer:
Since the sample size is larger than 30, the cognitive psychologist can assume that the sampling distribution of M will be approximately normal.
Step-by-step explanation:
We use the central limit theorem to solve this question.
The Central Limit Theorem estabilishes that, for a random variable X, with mean and standard deviation , a sample size larger than 30 can be approximated to a normal distribution with mean and standard deviation
So
Since the sample size is larger than 30, the cognitive psychologist can assume that the sampling distribution of M will be approximately normal.
Answer:
6
Step-by-step explanation:
Since the 36 balloons are being divided evenly into 6 groups, you divide the 36 by 6. Once you do this, you are left with 6.
Answer:
x-3
Step-by-step explanation:
(x
