Answer:

86 pieces

Step-by-step explanation:

Given

Pole = 500cm

Pieces = 5.8cm

Required

Determine the largest number of rods

To do this, we simply divide the length of the pole by the length of each piece.

Number = \frac{Pole}{Pieces}

Number = \frac{500cm}{5.8cm}

Number = \frac{500}{5.8}

Number = 86.2068965517

Round down

Number = 86

HG is the perpendicular bisector of FK.<br> What is the length of GH?<br> 8<br> 9<br> 15<br> 34
igor_vitrenko [27]

Answer:

GH=15

Step-by-step explanation:

HK= FK/2= 16/2= 8

Using pythagoras theorem in triangle GHK,

GH²= GK²-HK²

= 17²-8²

= 225

GH= √225

=15

A professor receives, on average, 24.7 emails from students the day before the midterm exam. To compute the probability of recei
MaRussiya [10]

Answer:

Let X the random variable that represent the number of emails from students the day before the midterm exam. For this case the best distribution for the random variable X is X \sim Poisson(\lambda=24.7)

The probability mass function for the random variable is given by:

f(x)=\frac{e^{-\lambda} \lambda^x}{x!} , x=0,1,2,3,4,...

The best answer for this case would be:

C. Poisson distribution

Step-by-step explanation:

Let X the random variable that represent the number of emails from students the day before the midterm exam. For this case the best distribution for the random variable X is X \sim Poisson(\lambda=24.7)

The probability mass function for the random variable is given by:

f(x)=\frac{e^{-\lambda} \lambda^x}{x!} , x=0,1,2,3,4,...

And f(x)=0 for other case.

For this distribution the expected value is the same parameter \lambda

E(X)=\mu =\lambda

And for this case we want to calculate this probability:

P(X \geq 10)

The best answer for this case would be:

C. Poisson distribution

Answer:

  (x, y, z) = (90, 75, 105)

Step-by-step explanation:

In a parallelogram, adjacent angles are supplementary, and opposite angles are congruent.

  (x -15) +(x +15) = 180

  2x = 180

  x = 90

Angles y and (x-15) are opposites, so ...

  y = x -15 = 90 -15 = 75

Similarly, for z ...

  z = x +15 = 90 +15 = 105

The values of x, y, and z are 90, 75, and 105, respectively.
