40i

The square root of any negative number is i and the the square root of 1600 is 40 so the answer is 40i.

Nope, you did step 4 and 5 wrong  

bappy hirthday

282 had been to a movie.

184 of those who had been to a movie had not been to a restaurant.

184 of 282 had not been to a restaurant.

So...

282 - 184 = 98 had been to a restaurant and movie.

there are 12 months in a year. Use the variable x for the month. thus we have

7(years) x 12(months)  = 84 months

We have a binomial probabilty here

Exactly three

C(12,4) (.41)^3 (.59)^9  ≈ 29.55%

At least 4  =

1 - C(12,0)(.59)^12 - C(12,1)(.41)(.59)^11 - C(12,2)(.41)^2(.59)^10 - C(12,3)(.41)^3(.59)^9  ≈ 79.5%

Less than 8  =

C(12,0)(.59)^12 + C(12,1)(.41)(.59)^11 + C(12,2)(.41)^2(.59)^10 + C(12,3)(.41)^3(.59)^9 +

C(12,4)(.41)^4(.59)^8 + C(12,5)(.41)^5(.59)^7 + C(12,6)(.41)^6(.59)^6 + C(12,7)(.41)^7(.59)^5 ≈ 93.38%

80 - 18 = 62 years

FV = PV x [1 + R]^N

FV = 50 x [1 + 0.021]^62

FV = 50 x  3.6274....

FV = $181.37 - The amount in your account by age 80.

OK i guess

69 its 69

Can you explain how you calculated it?

(b) atleast 4

Thx so much!! \ (•◡•) /

maybe 282 because it said they went to a movie but never said that they didn't go to a resturaunt

If the area experiences humidity levels above 90% or more 70% of the time.....then 30% of the time the humidity level is below 90%

And 3 weeks  =  21 days  .....so.....

21 days * 30% of these  =   about 6.3 days  =  6 days (rounded)

Thanksss CP!! It helped me too 

Cphill: A minor correction: 1.25 [ 3.25 + 2.5 + 1.75 ] + [ 1.05 * 0.5 ] =9.9 cm^2

Thanks so much!!! Yhea pherphas I made a mistake thankss againn!!

The area is given by :

1.25 [ 3.25 + 2.5 + 1.75 ] + [ 1.05 * 0.5 ] =

1.25 ( 7.5)  + .525 =

9.375 + .525  =

9.9 cm^2

Thanks to the guest for spotting my earlier mistake....
