$2\frac{1}{7}*\frac{1}{3}=\frac{15}{7}*\frac{1}{3}=\frac{15*1}{7*3}=\frac{15}{21}=\frac{5}{7}$
$\frac{5}{7}*60=\frac{5*60}{7}=\frac{350}{7}=42,(857142)min\approx 42.86min$

The tallest living man at one time had a height of 262 cm. The shortest living man at that time had a height of 68.6 cm. Heights

AysviL [449]

Answer:

more the z-score more will be the extreme. therefore tallest man has high extreme

Step-by-step explanation:

Formula for z-score: $\frac{X-\mu }{\sigma}$

where

X is height of tallest man

μ mean height

σ is standard deviation

z score for tallest is

z-score = $\frac{ 262 - 175.32}{8.17} = 10.60$

similarly for shortest man

z-score = $\frac{68.6 - 175.32}{8.17} = - 13.06$

more the z-score more will be the extreme. therefore tallest man has high extreme

A beach ball rolls off a cliff and onto the beach. The height, in feet, of the beach ball can be modeled by the function h(t)=64

Karolina [17]

Answer:

rate of change = -32 feet/second

Step-by-step explanation:

h(t) = 64 – 16t2

t = time (seconds)

Look at the start of time where t = 0

h(t) = 64 - 16 * (0) * 2 = 64 feet

Then look at the specified time where t = 1.25 seconds

h(t) = 64 - 16 * (1.25sec) * 2 = 24 feet

rate of change = rate of change y / rate of change x

x = time, y = height

rate of change = (24 - 64) / (1.25 - 0) = -32 feet/second
