You randomly choose an undergraduate student from a large state university. Let E be the event that the student is male, let F b
erik [133]

Answer:

( a ) is the right answer .

Step-by-step explanation:

P(E) = 0.48

Probability of being male = .48

Probability of being female = .52

P(F) = 0.72

Probability of being in state  = .72

Probability of being out of state  = .28

P(G) = 0.55

Probability of being in at least 20 years   = .55

Probability of being less than 20  = .45

a )

P(student is an in-state male younger than 20)

= .72 x .48 x .45 = .1555 = .156

b )

P(student is an out-of-state female younger than 20)

= .28 x .52 x .45

= .065

c )

P(student is an in-state female younger than 20)

= .72 x .52 x .45 = .168

d )

P(student is an out-of-state male at least 20)

= .28 x .48 x .55 = .074

So , ( a ) is the right answer .

The mean weight of five complete computer stations is 167.2 pounds. The weights of four of the computer stations are 158.4 pound
Lynna [10]

The mean weight of five complete computer stations is 167.2 pounds.

The weights of four of the computer stations are 158.4 pounds, 162.8 pounds, 165 pounds, and 178.2 pounds.

We have to determine the weight of fifth computer station.

Let the weight of fifth computer station be 'x' pounds.

Mean is calculated by sum of all the observations divided by the total number of observations.

So, \frac{158.4+162.8+165+178.2+x}{5}=167.2

\frac{664.4+x}{5}=167.2

{664.4+x}=167.2 \times 5

{664.4+x}=836

x= 171.6 pounds

The weight of fifth computer station is 171.6 pounds.

Soloha48 [4]

The circle's square is an inscribed square.

  1. Rafael made his first error in (B) Dividing the circle in six parts.
  2. The square can be constructed by first (c) Drawing a diameter
<h3>How to spot Rafael's mistake?</h3>

CIRCLE: A circle is the collection of all points on a plane that are at a specified distance from another point (the radius) (the centre). A radius is any distance separating a point on a circle from its center. Any two radii are equal in length under the concept of a circle.

SQUARE: In geometry, a square is a flat shape having four equal sides & four right angles (90°). A square is an unique sort of parallelogram as well as an equilateral rectangle.

Estimation for the error;

The diameter of a circle must be drawn first when drawing the square inside of a circle, following the circle itself.

This indicates that Rafael made two mistakes: first, he divided the circle into six halves, forgetting that a square is produced by first sketching a diameter.
