Answer:
The scores are between 50 and 90
Step-by-step explanation:
When we say middle 95%, we means that this value falls between 2 standard deviations of the mean i.e
μ ± 2σ
Hence,
mean of 70 and a standard deviation of 10
μ ± 2σ
μ - 2σ
70 - (2 × 10)
= 70 - 20
= 50
μ + 2σ
= 70 + (2 × 10)
= 70 + 20
= 90
It is 322 oz. if you multiply 13 times 24
cubic means 3 so there is a total o 3 roots
there is 1 real zero ( where the line crosses the x axis) the other 2 would be complex zeros
