A study of 12,000 able-bodied male students at the University of Illinois found that their times for the mile run were approxima
den301095 [7]

Answer:

P (y < 6) = \frac{P(y- \mu)}{\sigma}  \mu}{\sigma} \\\\=P(z

Therefore the probability that a randomly selected student has time for mile run is less than 6 minute is 0.0618

Step-by-step explanation:

Normal with mean 6.88 minutes and

a standard deviation of 0.57 minutes.

Choose a student at random from this group and call his time for the mile Y. Find P(Y<6)

\mu = 6.88

\sigma = 0.57

y ≈ normal (μ, σ)

The z score is the value decreased by the mean divided by the standard deviation

P (y < 6) = \frac{P(y- \mu)}{\sigma}  \mu}{\sigma} \\\\=P(z

Therefore the probability that a randomly selected student has time for mile run is less than 6 minute is 0.0618

Answer:

222.7 cm³ of paper to wrap this.

Step-by-step explanation:

The rectangular prism is SA=2(wl+hl+hw)

Where:

w=5  l=5 h=4  

SA= 2((5*5)+(4*5)+(4*5))

SA=2(25+20+20)

SA=2(65)=130cm³

The square base pyramid is A= lw+l\sqrt{x} (w/2)^2+h^2+w +w\sqrt{x} (1/w)^2+h^2

SA= 6*5+6*\sqrt{x} (5/2)^2+5^2+5*\sqrt{x} (6/2)^2

≈92.69578 cm³

Add the two together 130+92.70 =222.7 cm³
