Answer:

about 25.13

Step-by-step explanation:

The formula of the circumference is 2pi * r

half of the diameter is r, r is the radius

8/2 = 4

2* pi*4

2*4 = 8

8*pi = ~25.13

Carl is boarding a plane. He has 222 checked bags of equal weight and a backpack that weighs 4kg. The total weight of Carl's bag
Advocard [28]
Well first of all, 'kg' means mass, not weight.

If the total mass of all his baggage is 35 kg, and the mass
of his backpack is 4 kg, then the combined mass of all of his
checked bags is  (35 - 4)  =  31 kg.

If all of his checked bags have the same mass, then the mass
of each one is

                        (31 kg / 222 bags)  =  139.64  grams/bag   (rounded)

Eric randomly surveyed 150 adults from a certain city and asked which team in a contest they were rooting​ for, either North Hig
Romashka-Z-Leto [24]

Answer:

B

Step-by-step explanation:

  • A 95% confidence level interval will have 0.52 (lower interval) & 0.68 (upper interval) which means that that if 90 individuals root for North HS then p value is 0.6 which will fall in the 95% confidence interval range.
  • For the option B the p value will also be same as in case A hence B is true as an alternative hypothesis.
  • We can calculate P value

         Confidence Interval = p ± z \sqrt{p(1-p)/n}

If F(x)=x^3-2x^2, which expression is equivalent to f(I) -2+i,-2-i,2+i,2-i
Romashka-Z-Leto [24]

Hello from MrBillDoesMath!

Answer:

2 - i

Discussion:

Evaluate F(x) = x^3 - 2 x^2 when x = i.

i^2 = -1 for i^3 = i ( i^2) = i (-1) = -i

So F(i) =  (i)^3 - 2 (i)^2                      

          =   -i     - 2(-1)

          = -i      +  2

          =  2      -  i


which is the last answer shown


Thank you,

MrB
