Answer:

The mean of the data is 3 inches, is false

Step-by-step explanation:

3, 3, 4, 4, and 6 inches.

To find the mean, add the numbers together and divide by the number of data points

( 3+3+4+4+6)/5 = 20/5 = 4

The median is the middle number

3, 3,    4,      4, and 6 inches.

The median is 4

The range is the largest number minus the smallest number

6-3 =3

A=(1/2)(b1+b2)h =

=(48x+68)in² = (1/2)( b1+(9x+12))8

=b1= 3x+5

Using the binomial distribution, it is found that the expected score of the game is of 21.

It is the probability of exactly x successes on n repeated trials, with p probability of a success on each trial.

The expected number of trials until q successes is:

[tex]E_s(X) = \frac{q}{p}[/tex]

In this problem, a die has a p = 1/6 probability of resulting in a 1, hence the expected number of trials is:

[tex]E_s(X) = \frac{1}{\frac{1}{6}} = 6[/tex]

In each trial, each outcome from 1 to 6 is equally as likely, hence the expected score of a single trial is given by:

[tex]E = \frac{1 + 6}{2} = 3.5[/tex]

Then, the expected score of the six trials is:

6 x 3.5 = 21.

The possible number of different phone numbers will be 128000000

The extent to which an event is likely to occur, measured by the ratio of the favourable cases to the whole number of cases possible.

In this exercise we have to use the knowledge of probability to find the phone number, so:

Answer:

Step-by-step explanation:

Remark

All triangles are made up of 3 angles totally 180 degrees.

In addition a right triangle has a measurement of 90 degrees.

The other two angles must add to 90 degrees as will. That is the definition of complementary. (2 angles add to 90 degrees).

Formula

x + 28 = 90

Solution

x + 28 = 90              Subtract 28 from both sides.

x+28 -28=90 - 28

x = 62

The measure of the second angle is 62

Answer:

Third option

Step-by-step explanation:

The y-intercepts are -2 and 3 so first option is wrong

One is dashed line and other is solid so one needs to have equal and other one shouldn't, so second option is wrong as both are less than but not also equal

Third option the -2 intercept one is less than or equal to And the slope is positive while the 3 intercept one is greater with negative slope.

The given graph represents the system of inequalities in the third option y ≤ 2x - 2 and y > -x + 3.

It is clear from the graph that one of the inequality has a solid graph line while other has a dotted graph line.

So one of the inequality must be of the form ≤ or ≥ and the other one is of the form < or >.

The only inequalities of this form in the options are,

y ≤ 2x - 2

y > -x + 3

Consider y = 2x - 2.

The points through the line are (0, -2), (1, 0), (2, 2), ...

At origin, (0, 0), 0 ≤ -2 is false. So (0, 0) does not include in the solution region.

So the solution region of y ≤ 2x - 2 is on the part of the line of y = 2x - 2 where (0, 0) is not included.

Consider y = -x + 3

Line passes through (0, 3), (1, 2), (2, 1), (3, 0),....

At (0, 0), 0 > 3, which is false.

So the solution region of y > -x + 3 does not contain the part where (0, 0) is included.

So the resulting graph is correct for this system of inequalities.

Answer:

Step-by-step explanation:

In rectangle, the diagonals are equal  bisect each other.

⇒ OA = OB

⇒ΔAOB is an isosceles triangle.

In ΔAOB,

x + x + 120 = 180°

  2x + 120 = 180

           2x = 180 -120

           2x = 60

             x = 30°

In ΔABD

∠A + ∠ABD ∠BDA = 180

90  + 30 + ∠BDA  = 180

                 ∠BDA = 180 - 90 -30 = 60°

ΔABD is 30 - 60 - 90 triangle.

The ratio of sides of 30-60-90 triangle is x : x√3 : 2x

x →shortest leg which is opposite ot 30°

∵ x = AD =  20

x√3 → longest leg which is opposite to 60°

x√3 ( AB) = 20*1.732

            AB   = 34.64

Area of rectangle = length * width

                              = 34.64 *20

                             = 692.8

                             ≈ 693 square units

Answer:

  f(x) = 6·sin(8(x -π/2))

Step-by-step explanation:

A transformed sine function with amplitude A, period P, and horizontal shift S can be written as ...

  f(x) = A·sin(2π/P(x -S))

__

The equation for A=6, P=π/4, and S=π/2 is then ...

  f(x) = 6·sin(8(x -π/2))

_____

Additional comment

The horizontal shift is equal to two full periods, so the shifted function is indistinguishable from the unshifted function.

Answer:

[tex]\sf\:Negative = \boxed{\sf\:\theta =\pi n_{1}+\frac{5\pi }{6}\text{, }n_{1}\in \mathbb{Z}}\\\sf\: Positive = \boxed{\sf\:\theta =\pi n_{1}+\frac{\pi }{6}\text{, }n_{1}\in \mathbb{Z}}[/tex]

Step-by-step explanation:

[tex]4 - 3 \sec ^ { 2 } \theta = 0[/tex]

Let's solve this.

Isolate sec²θ.

[tex]4 -3 \sec ^ { 2 } \theta = 0\\- 3 \sec^{2}\theta = -4\\3 \sec^{2}\theta=0\\\sec^{2} \theta=\frac{4}{3}[/tex]

Now, we now that, cos θ is the reciprocal of sec θ. Therefore,

[tex]\sec^{2}\theta = \frac{4}{3}\\\cos^{2}\theta = \frac{3}{4}[/tex]

Bring the square root on both the sides of the equation to remove the square.

[tex]\sqrt{\cos^{2}\theta} = \sqrt{\frac{3}{4} }\\\cos^{2}\theta = (+/-) \frac{\sqrt{3} }{2}[/tex]

If,

[tex]\cos\theta = + \frac{\sqrt{3}}{2}\\= cos \left( \frac{\pi}{6} \right)\\\Longrightarrow \boxed{\sf\:\theta =\pi n_{1}+\frac{\pi }{6}\text{, }n_{1}\in \mathbb{Z}}[/tex]

Also if,

[tex]\cos\theta = -\frac{\sqrt{3}}{2}\\= \cos \left(\pi - \frac{\pi}{6}\right)\\= \cos \left({\frac{5\:\pi}{6}\right)\\\Longrightarrow \boxed{\sf\:\theta =\pi n_{1}+\frac{5\pi }{6}\text{, }n_{1}\in \mathbb{Z}}[/tex]
