A researcher is interested in the lengths of Salvelinus fontinalis (brook trout), which are known to be approximately Normally d
kompoz [17]

Answer:

c. 0.1151

Step-by-step explanation:

d) the probability that, on average, fish are larger than 86 centimeters in length.The area under part of a normal probability curve is  directly proportional to probability and the value is calculated as

z = (x₁−x) /σ

where z = propability of normal curve

x₁ = variate mean = 86cm

x = mean of 80cm

σ = standard deviation = 5cm

applying the formula,

z= (86-80)/5

z = 6/5 =1.2

Using a table of partial areas beneath the standardized normal curve (see Table of normal curve, a z-value of 1.2 corresponds to an area of 0.3849 between the mean value. but, because the standard curve has 0.5, then will minus 0.3849 from 0.5= 0.5 - 0.3849 = 0.1151

Thus the probability of a fish are larger than 86 centimeters in length is 0.1151

Will it cost more to rent from Company A or Company B if "Ali" rents the bounce house for 3 hours? 5 hours? 10 hours?
a_sh-v [17]

Answer:

3 HOURS : company A costs more

5 HOURS : Cost is the same

10 HOURS : Company B costs more

Step-by-step explanation:

Company A :

Rental fee = $100

Hourly rate = $20

Company B:

Hourly rate = $40

Cost of renting a bounce house from each company for h hours ;

Company A:

Total cost = 100 + 20h

Company B:

Total cost = 40h

If h = 3

Company A:

100 + 20(3) = $160

Company B:

40(3) = $120

FOR h = 5;

Company A:

100 + 20(5) = $200

Company B:

40(5) = $200

FOR h = 10;

Company A:

100 + 20(10) = $300

Company B:

40(10) = $400
