At a sea port, the depth of water, h meters, at time t hours, during a certain day is given by: h=6.7sin(2π((t-4)/12.4)) -3.1 what is the maximum depth of the water? 9.8m
6.7m
10.7m
3.6m

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2

happy to

pls mark as brainliest

answer: plz put a pic in so i can answer it

step-by-step explanation:

the answer is y = 11.54

hope this : )

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33
