Answer:
Step-by-step explanation:
Let the smaller number be . Since they are consecutive even numbers, the larger number can be represented by .
Therefore, we have the following equation:
Thus, the larger number is
Answer:
b)The sample size is large enough to use the normal approximation.
Step-by-step explanation:
In one case when sample size is very large usually, the Normal Distribution can be used to calculate an approximate probability of an event. The explanation of this is expained by the Central Limit Theorem which states that when we have a sample size is large, the sampling distribution of means converge to a normal distribution (approximately) and on this way:
The Binomial distribution can be approximated using a Normal Distribution in case when sample size is large. We can consider a sample size is large when we have these two conditions:
np > 10 and n(1-p)>10,
On this case we can assume the random variable
If we check the conditions:
np=493*0.05=24.65>10
n(1-p)=493*(1-0.05)=468.35>10
So then we can conclude that b)the sample size is large enough to use the normal approximation.
Answer:
There are 220 ways by which the medals can be awarded to three of the 15 gymnast, if exactly one of the Americans wins a medal
Step-by-step explanation:
From the question, we have;
The number of gymnast in the Olympic women's competition = 15
The number of the gymnast who are Americans = 4
The number of medals awarded = 3 medals
The number of ways hat the medals can be awarded to the three of the gymnast if exactly one of the Americans wins a medal is given as follows;
The number of ways one of the medals can be won by one of the four Americans = ₄C₁ = 4 ways
The number of ways the other two medals can be won by the remaining 11 gymnast = ₁₁C₂ = 55 ways
Therefore, the total number of ways, 'N', the medals can be awarded to three of the 15 gymnast, if exactly one of the Americans wins a medal is given as follows;
N = ₄C₁ × ₁₁C₂
∴ N = 4 × 55 = 220
$10 / 25 = 0.4
$18.50 / 50 =0.37
$27.20 / 80 = 0.34
