B. 30.47.

<h3>What is the mean of a discrete distribution?</h3>

The expected value of a discrete distribution is given by the <u>sum of each outcome multiplied by it's respective probability</u>.

Hence, considering the table, the mean of the discrete distribution is:

E(X) = 23 x 0.16 + 25 x 0.09 + 26 x 0.18 + 31 x 0.12 + 34 x 0.24 + 38 x 0.21 = 30.47.

Hence option B is correct.

Sara can type 90 words in 4 minutes.About how many words would you expect her to type in 10 minutes?
Alexus [3.1K]
90 words in 4 minutes is the same as 45 words in 2 minutes because you divide both sides by 2.  2 goes into 10, 5 times, so 45x5=225.
You can expect her to type 225 words in 10 minutes.

10. If 1000 cm = 1 l, find the capacity of the following water tank in litre
Lelu [443]
<h2>Given :</h2>

  • length = 200 cm

  • breadth = 150 cm

  • height = 100 cm

<h2>Solution : </h2>

\large \boxed{volume = l \times b \times h}

  • 200 \times 150 \times 100

  • 3000000  \: \: cm {}^{3}

Through the statement above we have,

  • \small\mathrm{1000  \: cm³ = 1  \:  \: }l

  • \small\mathrm{1 \: cm {}^{3}  =  \dfrac{1}{1000} \: }l

  • \small\mathrm{3000000 \: cm {}^{3}  = 3000000 \times  \dfrac{1}{1000}  \: }l

  • \small\mathrm{3000000 \: cm {}^{3}  = 3000000 \times  \dfrac{1}{1000}  \: }l

  • \small\mathrm{ 3000 \:  \: litres}
