Step-by-step explanation:
Using cosine rule,
f² = g² + e² - 2(g)(e)(cosF) = 6.7² + 5.9² - 2(6.7)(5.9)(cos70°)
= 52.6598 in²
Hence f = 7.3 in.
Answer:
The answer 2400.
Step-by-step explanation:
2×10^3=2×1000=2000
4×10^2=4×100=400
2000+400=2400
In order to calculate the z-score of a normal distribution, you need to apply the formula:
z = (o - m) / s
where:
o = observed value
m = mean
s = standard deviation
In your case:
z = (259 - 239) / 25 = 0.8
The answer is, indeed, z = 0.8
Just take them separately. so how many 6 oz glasses can you fill?
1284/6 = 214
how many 12 oz glasses?
1284/12 = 107
then find the difference between the two
214-107= 107
107 more glasses can be filled
