The correct answer it is 18 perimeter
Answer:
1/3 of the original
Step-by-step explanation:
As an an object is scaled up with the same proportions, one might think ts strength to weight ratio scales up with it. However, since the object as it scales greater in size also increases in weight, the strength to weight ratio actually decreases. If the elephant is scaled up 3 times, then its strength to weight ratio is divided by the same amount and is 1/3 the original or 1/3 as much.
X=22
2/3 = 18/(x+5)
2(x+5) = 18x3
2x + 10 = 54
2x = 44
x = 22
Answer:
(a) P(X>32.73) = 0.2912
(b) Out of 95 bottles, 28 would contain more than 32.73 oz of ale.
Step-by-step explanation:
(a) The amount of fill is normally distributed so we will calculate the z-score and then use it to find the probability using the normal distribution probability table.
Let the amount of fill be denoted by X. The z-score can be computed using the formula:
z = (X - μ)/σ
where μ = mean value of fill
σ = standard deviation of value of fill = √Variance
P(X>32.73) = 1 - P(X<32.73)
= 1 - P((X-μ)/σ < (32.73 - 32.7)/√0.003)
= 1 - P(z<0.55)
Using the normal distribution table in Appendix B, we can see the probability at z=0.55 is 0.7088. So,
P(X>32.73) = 1 - 0.7088
P(X>32.73) = 0.2912
(b) We are buying 95 bottles and we need to calculate how many of them contain more than 32.73 oz. For that, we will multiply the total number of bottles by the probability of finding more than 32.73 oz which we have calculated in (a).
95 * 0.2912 = 27.664
Rounding off to a whole number we get 28 bottles.
