Answer:
The following histogram shows the relative frequencies of the height recorded to the nearest inch of population of women the mean of the population is 64.97 inches and the standard deviation is 2.66 inches
(a) Based on the histogram, what is the probability that the selected woman will have a height of at least 67 inches? Show your work
Answer:
0.22268
Step-by-step explanation:
z-score is z = (x-μ)/σ,
where x is the raw score
μ is the population mean
σ is the population standard deviation.
(a) Based on the histogram, what is the probability that the selected woman will have a height of at least 67 inches? Show your work
At least means equal to or greater than 67 inches
z = 67 - 64.97/2.66
z = 0.76316
P-value from Z-Table:
P(x<67) = 0.77732
P(x>67) = 1 - P(x<67) = 0.22268
The probability that the selected woman will have a height of at least 67 inches is 0.22268
Step-by-step explanation:
At the beggin there are 150 eggs, after making 1 omeltet, there are 144 eggs, after the second omelet, there are 138 eggs, etc.
By the given statement you can notice that each omelet demands 6 eggs. Then, after making each omeltet Al has 6 eggs lower. This can wrtten numerically as follow:
150, 144, 138, 132, 126, 120,...
That is equivalent to:
150-6, 150-6-6, 150-6-6-6, 150-6-6-6-6, 126-6-6-6-6-6, ... , 150 - 6n
where n is the nth omelet made by counting from the begining of the day.
Answer:
for (8,4) is 2 and for (20,_4) is _5
Answer:
Step-by-step explanation:
1. Move the 6 to the other side: x^2 +4x =6
2. Square half the coefficient of the x term: (4/2)^2 = 4
3. Add this 4, and then subtract this 4, from x^2 + 4x:
x^2 +4x + 4 - 4 =6
4. Rewrite this perfect square as the square of a binomial:
(x + 2)^2 - 4 = 6
5. Add 4 to both sides: (x + 2)^2 = 10
6. Find the sqrt of both sides: x + 2 = √
Answer:
yup you are correct. The answer is 144 :)
