Answer:

  3 days

Step-by-step explanation:

You can estimate the answer (correctly) by observing that 3 × 70 is 210. This is close enough to 232.85 that you know the number of rental days is not 2 or 4.

The equation for the number of days (d) is ...

  73.95d +11 = 232.85 . . . $73.95 per day plus an extra fee

  73.95d = 221.85 . . . . . . subtract 11

  d = 221.85/73.95 = 3 . . . . divide by the coefficient of d

The saw was rented for 3 days.

Each letter of the word "supercalifragilisticexpialidocious" is placed into a bag and drawn at 3 times, replacing the letter aft
Makovka662 [10]

Answer:

P(X ≥ 1) = 0.50

Step-by-step explanation:

Given that:

The word "supercalifragilisticexpialidocious" has 34 letters in which 'i' appears 7 times in the word.

Then; the probability of success = 7/34 = 0.20588

Using Binomial distribution to determine the probability; we have:

P(X = x)  = ^nC_x  \ \beta^x   \  (1 - \beta)^{n-x}

where;

x = 0,1,2,...n    and    0  <  β   <   1

and x represents the  number of successes.

However; since the letter is drawn thrice; the probability that the letter "i" is drawn at least once can be computed as:

P(X ≥ 1) = 1 - P(X< 1)

P(X ≥ 1) = 1 - P(X =0)

P(X \ge 1) =  1 - \bigg [ {^3C__0} (0.21)^0 (1-0.21)^{3-0} \bigg]

P(X \ge 1) =  1 - \bigg [ 1 \times 1 (0.79)^{3} \bigg]

P(X ≥ 1) = 1 - 0.50

P(X ≥ 1) = 0.50

zubka84 [21]

Answer:

$1.375 ≈ $1.38

Step-by-step explanation:

First, set up a proportion:

\frac{16\textrm{ oz}}{\$1.10}}\times\frac{20\textrm{ oz}}{x}

Then, cross-multiply and solve for x:

(16)(x)=(20)(1.10)\\16x=22\\x=\frac{22}{16}\\x=1.375
