Answer:
Standard deviation, ∂ = 64.21 days
Mean = 429.21 days
Step-by-step explanation:
Given:
Mean lifespan = 71.45 years
Standard deviation = 12.35 years
Standard deviation, ∂ = x - µ / N
Where,
∂ = standard deviation
µ = mean life span
x = size of year
x = 70 years
Standard deviation, ∂ = x - µ / N
= 70 - (71.45 / 12.35)
= 70 - 5.79
= 64.21
Standard deviation, ∂ = 64.21 days
Mean = ∑x + standard deviation
∑x = 365
Mean = ∑x + standard deviation
= 365 + 64.21
= 429.21 days
Mean = 429.21 days
<span>1) If we mix up 350g of sugar with some water to make 70% sugar syrup, then
70% of sugar syrup weight is equal to weight of sugar, i.e. 350g
total weight of sugar syrup will be
350 * 100/70 = 500 g
2) Similarly, total weight of 30% sugar syrup made with 75g of sugar will be
75 * 100/30 = 250 g</span>
Answer:
