The probability that no one in the family of 4 will be hospitalized during a year is 0.52

Step-by-step explanation:

The probability for a person to be hospitalized during one year is

p(h)=0.15

As a consequence, the probability for a person of NOT being hospitalized during one year is

p(h^{-1})=1-0.15=0.85

If we have 4 people in the family, the probability of each of them of NOT being hospitalized during the year is independent from the probability of the others - therefore, these are independent events. This means that the total probability of the 4 people of not being hospitalized during a year is:

p(h^{-1})^4=(0.85)^4=0.52

So, the probability that no one in the family of 4 will be hospitalized during a year is 0.52.

<h3>Answer: Choice B) 8.57</h3>

==================================================

Explanation:

The triangles are similar through the AA (angle angle) similarity rule. Note how the angle markers correspond and match up. Example: angle C and angle F both have triple angle markers to indicate these angles are congruent.

The corresponding sides pair up to form equal fractions. AB and DE form AB/DE which is equal to AC/DF, as these two sides correspond as well.

Therefore: AB/DE = AC/DF

Let's plug in the given values and isolate x

AB/DE = AC/DF

11/7 = (15+x)/15 ...... substitution

11*15 = 7*(15+x) ....... cross multiply

11*15 = 7*15+7*x ...... distribute

165 = 105+7x

165-105 = 105+7x-105 ..... subtract 105 from both sides

60 = 7x

7x = 60

7x/7 = 60/7 ............ divide both sides by 7

x = 8.57142857142858

x = 8.57 ..... rounding to the nearest hundredth

if you were to solve the following system by substitution what would be the best variable to solve and from what equation? 2x+8y
Nina [5.8K]
All the numbers in the first equation have a common factor of 2. Removing that gives
.. x +4y = 6
making it easy to solve for x
.. x = 6 -4y

My choice would be to solve for x using the first equation.

_____
On second thought, it might actually be easier to solve either equation for 8y. That term then directly substitutes into the other equation (equivalent to adding the two equations).
.. 8y = 3x -11 . . . . . from the second equation
.. 2x +(3x -11) = 12 . . . substituting into the first equation
.. 5x = 23 . . . . . . . . . . collect terms, add 11 (what you would get by adding the equations in the first place)
.. x = 4.6
.. y = (3*4.6 -11)/8 = 0.35

rusak2 [61]

Answer:

  -12.5%

Step-by-step explanation:

The percentage change in your time can be computed using ...

  pct change = ((new value)/(old value) -1) × 100%

  = (28/32 -1) × 100%

  = (0.875 -1) × 100% = -12.5%

The time to finish level 2 decreased by 12.5%.
