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
Answer:
15
Step-by-step explanation:
From the given information:
The distance of one consecutive number on a number line to the other is usually 1.0.
To round up 14 5/6 to the nearest whole number, we need to take a proper look at the improper fraction 5/6.
We know that:
6/6 = 1
3/6 = 0.5
5/6 is more than 3/6 and the decimal form is approximately 0.8
Thus 14+0.8 = 14.8, and that is approximately 15 on a number line.
Answer:
Step-by-step explanation:
sin A= 21/29
cos A=20/29
tan A=21/20
sin B =20/29
