Answer:
£450
Step-by-step explanation:
using the formula C = 12×m.p + d
£8000 = 12m.p + £2600
collecting like terms, £8000 - £2600 = 12m.p
£5400 = 12m.p
dividing by coefficient of m.p,
£5400/12 = 12m.p/12
when you divide,
£450 = m.p
hence, m.p = £450

Answer:
99.7%
Step-by-step explanation:
Note that 92 and 128 are 3 standard deviations from the mean
The emperical rule or the 68–95–99.7 rule states that 68% of outcomes are wihtin 1 standard deviation from the mean
95% of outcomes are within 2 standard deviations from the mean
99.7% of outcomes are within 3 standard devations from the mean
This is 3 standard deviations so the answer is 99.7
Answer:
Step-by-step explanation:
Formulas to know:
- Area of a circle:
- Circumference of a circle:
Since we know the circumference, we can use formula for the circumference of a circle to find the circle's radius:
Now we can plug in into the formula for an area of a circle:
