Answer:

[tex] \frac{2}{5} [/tex]

Step-by-step explanation:

The probability of event A happening is denoted by P(A). The probability of event A happening is given by the formula below:

[tex]\boxed{P(A) = \frac{number \: of \: favourable \: outcomes \: in \: A}{total \: possible \: outcomes}} [/tex]

Since there are 2 black pens, and only one pen is chosen, the number of favourable outcomes in choosing a black pen is 2.

The total possible outcomes is the total number of pens in this case.

P(black pen)

[tex] = \frac{2}{2 + 2 + 1} [/tex]

[tex] = \frac{2}{5} [/tex]

This is the theoretical probability as it is not determined from experimental results.

Answer:

bag B

Step-by-step explanation:

bag A: 5R and 2G

bag B: 7R and 3G

Bag A probability for green is 2/7

bag B probability for green is 3/10

if we convert the fractions to have a common denominator:

bag A: 20/70

bag B: 21/70

so bag B has the greater probability of drawing a green marble

The net below represents a container. What solid figure does it show?

We can see that the given net has 12 edges, 6 faces and 8 vertices if we compile it up. These number of edges, faces and vertices are found in a cuboid or a rectangular prism. With this we can conclude that if we compile the given net, it will form a cuboid or a rectangular prism. So, the given net is of a cuboid or a rectangular prism.

The given net is of a cuboid or a rectangular prism.

Answer: 19 years

Step-by-step explanation:

Given

Amount invested [tex]\$400[/tex]

Rate of interest [tex]R=6\%[/tex]

after 1-year amount becomes

[tex]A=400\left (1+6\%\right)\\A=400\left (1+0.06\right)\\A=400\times 1.06\\A=\$424[/tex]

After n years it is

[tex]A=400\left (1.06\right)^n[/tex]

Sum accumulated is [tex]\$1200[/tex]

[tex]\Rightarrow 1200=400\left(1.06\right)^n\\\Rightarrow 3=\left(1.06\right)^n\\\text{Taking log both sides}\\\Rightarrow n=\dfrac{\ln 3}{\ln 1.06}\\\\\Rightarrow n=18.85\approx 19\ \text{years}[/tex]

Answer:

  2) 198°

  4) 99°

  6) 90°

Step-by-step explanation:

The relevant relations are ...

__

2) Arc WXY = 2×angle WDY = 2(99°) = 198°

__

4) Arc CLE is 2×angle CDE = 2(97°) = 194°

  Arc DE = 360° -72° -194° = 94°

  angle C = (arc DE +arc EL)/2 = (94° +104°)/2 = 99°

__

6) angle C = (360° -arc EC -arc CD)/2 = (360° -71° -109°)/2 = 90°

Answer:

2.

Given:

m arc WXY=2×99°=198°[central angle is equal to the twice of its inscribed angle]

4.Arc CLE =2x< CDE = 2×97° = 194°[central angle is equal to the twice of its inscribed angle]

again

Arc DE =360° -72° -194° = 94°[from complete turn]

and

angle C =½ (arc DE +arc EL) =½ (94° +104°) = 99°

6) angle C =½ (360° -arc EC -arc CD)

=½ (360° -71° -109°)= 90°

Answer:

[tex]\cos(W) = \frac{9}{41}[/tex]

Step-by-step explanation:

Given

[tex]\angle Y = 90^o[/tex]

[tex]YX = 40; XW = 41; WY = 9[/tex]

Required

Determine [tex]\cos(W)[/tex]

The question is illustrated with the attached image.

So:

[tex]\cos(W) = \frac{Adajacent}{Hypotenuse}[/tex]

[tex]\cos(W) = \frac{WY}{XW}[/tex]

This gives:

[tex]\cos(W) = \frac{9}{41}[/tex]

Answer:

Shalini

The maximum amount that she would be willing to pay for an insurance policy that completely covers any auto damages is:

= $150.

Step-by-step explanation:

Utility for money, u(x) = x1/2

x, her final wealth level = $1,600

Loss from accident

Probability     Loss incurred    Expected Loss

90%                  $0                            $0 (90% * $0)

10%                   $1,500                 $150 (10% * $1,500)

100%                                             $150

b) The amount that Shalini would be willing to pay for an insurance policy for all auto damages is limited to her expected loss from auto damages.  Since she has a 90% chance of not being involved in an accident, her expected loss will be reduced to $150.  This represents 10% of the loss from damages that she would incur if she was involved in an accident, which is 10% probable.

Answer: Most of the students are 67 or 68 inches tall.

Step-by-step explanation:

From the information given, option A is correct as six students are taller than 68 inches.

Also, most of the students are 67 inches tall since there are 9 students who are 67 inches tall. Also, only one student is 65 inches tall.

The best description of the data is that most of the students are 67 or 68 inches tall. 9 students are 67 inches tall while 8 students are 68 inches tall. This means 17 out of 25 students have those heights. Therefore, most of the students are 67 or 68 inches tall is the correct option.

Only six students (24 percent) are taller than 68 inches.

According to provided data set consisting of height measurements for a group of students.

The data has been organized into a tally chart,

with each tally representing one student's height falling within a particular category.

To analyze this data further,

we can calculate the cumulative frequency for each height category.

The cumulative frequency is the sum of the frequencies up to and including the current category.

Using the provided data,

we can calculate the cumulative frequency as follows,

65" | 1 |

cf = 1 66" | 1 |

cf = 2 67" |||| 9 |

cf = 11 68" ||| 8 |

cf = 19 69" ||| 3 |

cf = 22 70" || 2 |

cf = 24 71" | 1 |

cf = 25

Based on this data,

we can make several observations.

Firstly, there is only one student who is 65 inches tall.

Secondly, most of the students (44% or 11 out of 25) are 67 inches tall, with a similar number (32% or 8 out of 25) being 68 inches tall.

Finally, only six students (24%) are taller than 68 inches.

Answer:

Option B.

Step-by-step explanation:

Inverse function:

Suppose we have a function y = f(x). To find the inverse function, we exchange x and y on the original function, and then isolate y.

The domain of the inverse function(x values) is the range of the original function(y values).

Original function:

[tex]f(x) = \sqrt{x} - 5[/tex]

Domain is [tex][0,\infty)[/tex], and when [tex]x = 0, f(x) = -5[/tex]. So the range is [tex][-5,\infty][/tex], that is, [tex]y \geq -5[/tex]

Inverse function:

[tex]y = \sqrt{x} - 5[/tex]

Exchanging x and y

[tex]x = \sqrt{y} - 5[/tex]

[tex]\sqrt{y} = x + 5[/tex]

[tex](\sqrt{y})^2 = (x+5)^2[/tex]

[tex]y = (x+5)^2[/tex]

The inverse function is [tex]f^{-1}(x) = (x+5)^2[/tex]

Domain:

Range of the original function is [tex]y \geq -5[/tex], so the domain of the inverse function is [tex]x \geq -5[/tex]. The correct answer is given by option B.
