<h3>Answer:  50</h3>

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

Work Shown:

55% = 55/100 = 0.55

55% of 200 = 0.55*200 = 110 people prefer dogs

30% of 200 = 0.30*200 = 60 people prefer cats

Subtract the results: 110-60 = 50

An art teacher has a roll of mural paper that is 5 meters long.
Ivenika [448]
<h3>Answer: 50</h3>

"deci" means tenth, so "decimeter" means "tenth of a meter"

0.10 meter = 1 decimeter

1 meter = 10 decimeters (multiply both sides by 10)

5 meters = 50 decimeters (multiply both sides by 5)

The teacher can get 50 pieces out of the roll of paper

professor190 [17]

Answer: N >/= 7 bits

Minimum of 7 bits

Step-by-step explanation:

The minimum binary bits needed to represent 65 can be derived by converting 65 to binary numbers and counting the number of binary digits.

See conversation in the attachment.

65 = 1000001₂

65 = 7 bits :( 0 to 2^7 -1)

The number of binary digits is 7

The air force reports that the distribution of heights of male pilots is approximately normal, with a mean of 72.6 inches and a
Anon25 [30]

Answer:

Step-by-step explanation:

<em>Given that X -  the distribution of heights of male pilots is approximately normal, with a mean of 72.6 inches and a standard deviation of 2.7 inches.</em>

<em />

<em>Height of male pilot = 74.2 inches</em>

<em />

<em>We have to find the percentile</em>

<em />

<em>X = 74.2</em>

<em />

<em>Corresponding Z score = 74.2-72.6 = 1.6</em>

<em />

<em>P(X<174.2) = P(Z<1.6) = 0.5-0.4452=0.0548=5.48%</em>

<em />

<em>i.e. only 5% are below him in height.</em>

<em />

<em>Thus the malepilot is in 5th percentile.</em>
