Comparing the standard deviations of each distribution, you have blue < red < yellow.

For any normally distributed random variable X with mean µ and standard deviation σ, we have the property that

Pr[|X - µ| ≤ σ] ≈ 68%

In other words, roughly 68% of a normal distribution lies within 1 standard deviation of the mean. This means the plot of the density of a distribution with a smaller standard deviation forms a tighter peak (like the blue curve), whereas a larger standard deviation would be indicated by a more dispersed, flattened curve (like the yellow one).

Answer:

[tex]A_{\Delta ABP}=\sin \theta[/tex]

Step-by-step explanation:

Let the center of the circle be O.

Recall that the area of a triangle can be given by:

[tex]\displaystyle A=\frac{1}{2} ab\sin C[/tex]

Where C is the angle between the two sides.

ΔABP is equal to the sum of ΔAPO and ΔBOP.

Let a = OP and b = OB. Since this is the unit circle and PO and BO are radii, they both equal one. C will be θ. Hence, the area of ΔBOP is:

[tex]\displaystyle A_{\Delta BOP}=\frac{1}{2}(1)(1)\sin \theta=\frac{1}{2}\sin\theta[/tex]

For ΔAPO, we can use the two sides OP and OA. Again, they are the radii of the unit circle, so they equal one. The angle in this case will be π - θ radians. Hence:

[tex]\displaystyle A_{\Delta APO}=\frac{1}{2}(1)(1)\sin\left(\pi -\theta\right)=\frac{1}{2}\sin\left(\pi -\theta\right)[/tex]

However, note that sin(π - θ) = sin(θ). Hence:

[tex]\displaystyle A_{\Delta APO}=\frac{1}{2}\sin\left(\theta\right)[/tex]

Hence, the area of ΔABP is:

[tex]\displaystyle A_{\Delta ABP}=\frac{1}{2}\sin \theta+\frac{1}{2}\sin\theta =\sin \theta[/tex]

Step-by-step explanation:

[tex](x + 5)(x - 2) \geqslant 0[/tex]

The solution of the inequality is x  ≥ -5 and x  ≥ 2.

The graph of the number line is given in the attached image.

In mathematics, "inequality" refers to a relationship between two expressions or values that are not equal to each other. To solve the inequality, you may multiply or divide each side by the same positive number, add the same amount to each side, take the same amount away from each side, and more. You must flip the inequality sign if you multiply or divide either side by a negative number.

Given:

An inequality (x+5)(x-2) ≥ 0

Solving further,

(x+5) ≥ 0 and (x -2)  ≥ 0

x  ≥ -5 and x  ≥ 2

Therefore, the solution of the inequality is x  ≥ -5 and x  ≥ 2.

So this is complicated, but to get a general idea simple we use common sense and say its bigger than 4, since its length is bigger than the supposed 4 length. So then we get  the options 6, 5, and 24. Now we can do some basic math and figure that the circle radius is around 4 so its probably 6 or 5. Slim change of 24.

35=2x-x

35=x

It is A) Slope: 2, y-intercept: -20

Answer:

110

Step-by-step explanation:

Supplementary angles add to 180

3x+5  +2x = 180

Combine like terms

5x +5 = 180

Subtract 5 from each side

5x = 175

Divide each side by 5

5x/5 = 175/5

x =35

DEF = 3x+5

    = 3*35 +5

   = 105+5

  = 110

Answer:

9.83cm

Step-by-step explanation:

Since we are not asked what to look for. We can find the height of the wall.

Let the height of the wall be H

Given

Length of the ladder l = 12fot

Angle of elevation = 55degrees

Required

Height of wall H

Using the SOH CAH TOA identity

SIn theta = opp/hyp

Sin 55 = H/12

H - 12sin55

H = 12(0.8192)

H = 9.83cm

Hence the height of the ladder is 9.83cm

Answer: d. 0.55

Step-by-step explanation:

The given probability distribution:

Number of Goals     0            1            2          3           4

Probability             .05           .15        .35       .30           .15

The probability that in a given game the Lions will score less than 3 goals

= probability that in a given game the Lions will score less than or equal to 2

= 0.5+0.15+0.35

= 0.55

Hence, the correct option is d. 0.55

Answer:

Step-by-step explanation:

1). If the given triangles are similar their corresponding sides will be proportional.

[tex]\frac{8}{a}= \frac{8}{12}=\frac{5}{b}[/tex]

[tex]\frac{8}{a}= \frac{8}{12}[/tex]

[tex]a=\frac{12\times 8}{8}[/tex]

[tex]a=12[/tex]

[tex]\frac{8}{12}=\frac{5}{b}[/tex]

[tex]b=\frac{5\times 12}{8}[/tex]

[tex]b=7.5[/tex]

2). By using proportional relationship in the similar polygons,

[tex]\frac{3}{c}=\frac{6}{8}[/tex]

[tex]c=\frac{8\times 3}{6}[/tex]

[tex]c=4[/tex]

d = 8

c = e = 4

3). If the pentagons are similar their corresponding sides will be proportional.

[tex]\frac{6}{g}=\frac{8}{18}=\frac{10}{h}= \frac{8}{I}=\frac{6}{f}[/tex]

[tex]\frac{6}{g}=\frac{8}{18}[/tex]

[tex]g=\frac{18\times 6}{8}[/tex]

[tex]g=13.5[/tex]

[tex]\frac{8}{18}=\frac{10}{h}[/tex]

[tex]h=22.5[/tex]

[tex]\frac{8}{18}=\frac{6}{f}[/tex]

[tex]f=13.5[/tex]

[tex]\frac{8}{18}= \frac{8}{I}[/tex]

[tex]I=18[/tex]

Answer: y=55  x=6

Step-by-step explanation: Because of the two equivalent lines in lines DE and FE we know that the angles D and F must be equal, therefore y is 55. And now we know that angles D and F add up to 110 and because all of the angles in a triangle add up to 180, angle E must equal 70.

Angle E-        (11x+4)=70

                            -4   -4

                       11x=66

                         divide both sides by 11

                            x=6

Answer:

x = -7,   y = 5

Step-by-step explanation:

a) x + 9y = 38,   b) 3x + 7y = 14

From a)

x = 38 - 9y ---- (Equation 1)

From b)

{3*(38 - 9y)} + 7y = 14 ----- (From equation 1)

114 - 27y + 7y -14 = 0

100 - 20y = 0

20y = 100

y = 5

From a)

x + (9*5) = 38  (substituting the value of y = 5)

x + 45 = 38

x = 38 - 45

x = -7
