Answer:

The probability is 1/12

Step-by-step explanation:

Probability is given by number of possible outcomes ÷ number of total outcomes

Rate of phone calls = 2.1 per minute

Total number of calls between 3:00 p.m and 4:00 p.m (60 minutes) = 2.1 × 60 = 126

Number of calls between 3:10 p.m and 3:15 p.m (5 minutes) = 2.1 × 5 = 10.5

Probability = 10.5/126 = 1/12

Which expression is equivalent to StartRoot StartFraction 25 x Superscript 9 Baseline y Superscript 3 Baseline Over 64 x Supersc
MAVERICK [17]

Answer:

\displaystyle \frac{5x}{8y^{4}}\sqrt{x}

Step-by-step explanation:

<u>Simplfy in Algebra </u>

We have the following expression

\displaystyle E=\sqrt{\frac{25x^9y^3}{64x^6y^{11}}}

Simplifying like factors in the denominator and numerator

\displaystyle E=\sqrt{\frac{25x^3}{64y^{8}}}

All the factors are perfect squares except x^3, thus we rewrite:

\displaystyle E=\sqrt{\frac{25xx^2}{64y^{8}}}

Taking the square root of all the perfect square factors:

\boxed{\displaystyle E=\frac{5x}{8y^{4}}\sqrt{x}}

As part of a summer internship, five people -- Cindy, Damaris, Eugenio, Fareed, and Guzal -- are to be assigned to floors 1-5 in
MrMuchimi

Based on the information, it is expected Fareed can be assigned to live on any of the floors.

<h3>What condition limits Fareed's assignment?</h3>

The only condition that limits the floor Fareed can be assigned to is that he cannot be immediately below Damaris. This means that as long as Damaris is not immediately above him, he can be assigned to all floors. Here are two possible arrangements:

  • Eugenio (5th floor)
  • Damaris
  • Cindy
  • Fareed
  • Guzal (1st floor)

  • Guzal (5th floor)
  • Eugenio
  • Damaris
  • Cindy
  • Fareed (1st floor)

Compare centers mean you need to compare the median of the two box plots.

Box 1: Median (Q2) = 40

Box 2: Median (Q2 is between 40 and 50 (40 < Q2 < 50)

So the center of box 2 is greater than center of box 1

Hope it helps.
