julia-pushkina [17]

Answer:

$13.20 or $2.20

Step-by-step explanation:

Since percents are decimals, we can figure out the tip by multiplying the total by the decimal percent.

11 x .20 = 2.2

Now the answer depends on what you need the answer to be. if you need the total, it's $13.20.

If you need the tip, it's $2.20.

Giovanna used the calculations below to determine the height of a stack of 7 books that are each 2 and StartFraction 5 over 8 En
igor_vitrenko [27]

The error Giovanna made in her calculation is multiplying 7 by 2 and adding with 5/8(step 3)

<h3>Fraction</h3>

Her calculation:

  • 7 (2 and StartFraction 5 over 8 EndFraction): 7(2 5/8)

  • 7 (2 + StartFraction 5 over 8 EndFraction): 7(2 + 5/8)

  • 14 + StartFraction 5 over 8 EndFraction: 14 + 5/8

  • 14 and StartFraction 5 over 8 EndFraction: 14 5/8

Her error was multiplying 7 by 2 and adding with 5/8(step 3)

Correct calculation:

7(2 + 5/8)

= 14 + 35/8

= (112+35) /8

= 147/8

= 18 3/8

The time between telephone calls to a cable television service call center follows an exponential distribution with a mean of 1.
Ulleksa [173]

Answer:

0.52763 is the probability that the time between the next two calls will be 54 seconds or​ less.

0.19285 is the probability that the time between the next two calls will be greater than 118.5 ​seconds.

Step-by-step explanation:

We are given the following information in the question:

The time between telephone calls to a cable television service call center follows an exponential distribution with a mean of 1.2 minutes.

The distribution function can be written as:

f(x) = \lambda e^{-\lambda x}\\\text{where lambda is the parameter}\\\\\text{Mean} = \mu = \displaystyle\frac{1}{\lambda}\\\\\Rightarrow 1.2 = \frac{1}{\lambda}\\\\\lambda = 0.84 \\f(x) = 0.84 e^{0.84 x}

The probability for exponential distribution is given as:

P( x \leq a) = 1 - e^{\frac{-a}{\mu}}\\\\P(a \leq x \leq b) = e^{\frac{-a}{\mu} -\frac{-b}{\mu}}

a) P( time between the next two calls will be 54 seconds or​ less)

P( x \leq 0.9)\\= 1 - e^{\frac{\frac{-54}{60}}{1.2}} = 0.52763

0.52763 is the probability that the time between the next two calls will be 54 seconds or​ less.

b) P(time between the next two calls will be greater than 118.5 ​seconds)

p( x > \frac{118.5}{60}) = P(x > 1.975)\\\\ = 1 - P(x \leq 1.975) \\\\= 1 -1+ e^{\frac{-1.975}{1.2}}\\\\= 0.19285

0.19285 is the probability that the time between the next two calls will be greater than 118.5 ​seconds.

In the triangle below, 21 = 35 and 3 = 100
vesna_86 [32]

Answer:

135

Step-by-step explanation:

Okay so we know that all angles in  tringle sums up to 180

Therefore ∠2 = 180 - ∠1 - ∠3 = 180 - 35 - 100 = 45deg

We also know that angles on a straight line add up to 180deg as well

Therefore ∠4 = 180 - ∠2 = 180 - 45 = 135deg
