Answer:
1. z = -1.91429
The z score tells us that the head circumference of the girl with the down syndrome ( 44.5 cm) is 1.91429 standard deviations below the mean or average head circumference
2. 2.7792%
Step-by-step explanation:
1. Relative to the WHO data, what is this girls z-score?
z score formula is:
z = (x-μ)/σ, where
x is the raw score = 44.5 cm
μ is the population mean = 47.18cm
σ is the population standard deviation = 1.40cm
z = 44.5 - 47.18/1.40
z = -1.91429
What does the z score tell us?
The z score tells us that the head circumference of the girl with the down syndrome ( 44.5 cm) is 1.91429 standard deviations below the mean or average head circumference
2. Using the WHO data in a normal model, what percentage of the girls has a head circumference that is smaller than the girl with Down's Syndrome?
z score = -1.91429
Probability value from Z-Table:
P(z =-1.91429) = P(x<44.5) = 0.027792
Converting to percentage = 0.027792 × 100
= 2.7792%
Answer:
Step-by-step explanation:
3000/10=300 300=10% of total missiles
300*3=900(30%) That country (assuming it is Iran) would produce 900 short missiles and 900 medium missiles. 3000-900(2)=3000-1800=1200.
Iran will produce 1200 long range missiles.
For the cost of the missiles,
200,000*900=180,000,000. 300,000*900=270,000,000.
870M-(180M+270M)=870M-450M=420M
420,000,000/1200=350,000.
Long Range Missiles are $350,000 each... got me thinkin bout buying some...
For this case we have the following function:
A (t) = P (1 + r / n) ^ nt
Substituting values we have:
A (4) = 500 * (1 + 0.09 / 1) ^ (1 * (4))
A (4) = 705.790805
Rounding we have:
A (4) = 705.79
Answer:
The answer for this case is given by:
A (4) = 705.79
option A
Answer:
41
Step-by-step explanation:
each page holds 7 discs. the alb holds 700 discs. that means there are 100 pages. 69% of the pages are empty so therefore 41 pages are filled.
