A number nn is 150% of number mm. Is nn greater than, less than, or equal to mm? Explain your reasoning.

1 answer:

4 0

Definitely greater. You are above 100%, it shouldn't be less than MM

EG:
MM = 100
150=1.5
100*1,5 = NN = 150

2. EG:

MM = 2345
2345*1,5 = 3517,5

Answer:

That's because numbers like 2,31, 50 and so on are integers while 2.4, √66 ND so on are not

For a:

(2400*2*PI)/60(seconds) = 80 PI RAD/Sec

For b:

arc length s= radius r * central angle(in radians)

= ((80*pi*7.5)/(2*pi)
=25

Answer: A. Mean of sampling means $=\mu=168\ Mg/dl$

Standard deviation of sampling means = $2.86\ mg/dl$

B. The probability that your sample has mean less than 165 is 0.1492 .

Given : The distribution of blood cholesterol level in the

population of young men aged 20 to 34 years is close to normal with

mean $\mu= 168$ Mg/dl and standard deviation $\sigma= 35$ mg/dl.

Sample size : n= 150

Let $\overline{x}$ sample mean values.

A. The mean and the standard deviation of the distribution of the sampling means would be :

Mean of sampling means = $\mu=168\ Mg/dl$

Standard deviation of sampling means = $\dfrac{\sigma}{\sqrt{n}}=\dfrac{35}{\sqrt{150}}$

$=\dfrac{35}{12.2474487}\\\\=2.85773803649\approx2.86\ mg/dl$

The probability that your sample has mean less than 165 would be

$P(\overline{x}$

Hence , the probability that your sample has mean less than 165 is 0.1492 .
