Step-by-step explanation:

(a)

Using the recursive rule and a₁ = 4 , then

a₂ = 2([tex]\frac{1}{3}[/tex] + a₁ ) = 2([tex]\frac{1}{3}[/tex] + 4) = 2 × 4 [tex]\frac{1}{3}[/tex] = 2 × [tex]\frac{13}{3}[/tex] = [tex]\frac{26}{3}[/tex]

a₃ = 2([tex]\frac{1}{3}[/tex] + a₂) = 2([tex]\frac{1}{3}[/tex] + [tex]\frac{26}{3}[/tex] ) = 2 × [tex]\frac{27}{3}[/tex] = 2 × 9 = 18

a₄ = 2([tex]\frac{1}{3}[/tex] + a₃) = 2([tex]\frac{1}{3}[/tex] + 18) = 2 × 18 [tex]\frac{1}{3}[/tex] = 2 × [tex]\frac{55}{3}[/tex] = [tex]\frac{110}{3}[/tex]

a₅ = 2([tex]\frac{1}{3}[/tex] + a₄) = 2([tex]\frac{1}{3}[/tex] + [tex]\frac{110}{3}[/tex]) = 2 × [tex]\frac{111}{3}[/tex] = 2 × 37 = 74

------------------------------------------------------------------------

(b)

Using the recursive rule and a₁ = 6 , then

a₂ = [tex]\frac{2}{a_{1} }[/tex] = [tex]\frac{2}{6}[/tex] = [tex]\frac{1}{3}[/tex]

a₃ = [tex]\frac{3}{a_{2} }[/tex] = [tex]\frac{3}{\frac{1}{3} }[/tex] = 9

a₄ = [tex]\frac{4}{a_{3} }[/tex] = [tex]\frac{4}{9}[/tex]

a₅ = [tex]\frac{5}{a_{4} }[/tex] = [tex]\frac{5}{\frac{4}{9} }[/tex] = 5 × [tex]\frac{9}{4}[/tex] = [tex]\frac{45}{4}[/tex]

------------------------------------------------------------------------

(c)

The sequence has a common ratio

r = [tex]\frac{\frac{2}{3} }{\frac{1}{6} }[/tex] = [tex]\frac{\frac{8}{3} }{\frac{2}{3} }[/tex] = 4

Multiply the previous terms by 4 , then

a₄ = 4 × [tex]\frac{8}{3}[/tex] = [tex]\frac{32}{3}[/tex]

a₅ = 4 × [tex]\frac{32}{3}[/tex] = [tex]\frac{128}{3}[/tex]

Answer:

Relationship exists between price and overall score

Step-by-step explanation:

Given the data:

Brand Price Score

Bose 180 76

Scullcandy 160 76

Koss 95 69

Phillips/O'Neill 70 58

Denon 80 50

JVC 35 26

Using the correlation Coefficient calculator ; the correlation Coefficient, R = 0.875

H0 : no relationship exists

H1 : relationship exists

Using the R Coefficient ;

The test statistic :

T = r / √(1 - r²) / (n - 2)

n = 6

The test statistic :

T = 0.875 / √(1 - 0.875²) / (4)

T =0.875 / 0.05859375

T = 0.9333

The Pvalue from test statistic :

df = n - 2 ; 6 - 2 = 4

Pvalue(0.933, 4) = 0.02246

At α = 0.05

Pvalue < α ; We reject H0 ; and conclude that relationship exists between price and overall score

Area = 12.82 miles²

Step-by-step explanation:

Area of a triangle with two adjacent sides and the inscribed angle between these side is given by,

Area = [tex]\frac{1}{2}ab[\text{sin(C)}][/tex]

By substituting the values of sides a, b and the angle C,

Area = [tex]\frac{1}{2}(5.7\times 9.3)[\text{sin}(14^{\circ})][/tex]

Answer:

1.an equilateral triangle is never similar to a scalene triangle.

2. because we can never map one onto the other using only dilations and rigid transformations.

This is because an equilateral triangle has all equal sides and the same angle measures, and a scalene triangle's sides are all different measures and the angles don't measure the same angle.

Answer:

B. The SAS Postulate

Step-by-step explanation:

In the given figure, we are shown two triangles, [tex]\triangle ADE[/tex] and [tex]\triangle ABC[/tex].

Since triangle ADE is inscribed in triangle ABC, both triangles must share angle [tex]A[/tex]. Furthermore, let's take a look at the two legs of each triangle, if we say that their respective bases are DE and BC.

Compare the corresponding legs of each triangle with proportions:

[tex]\frac{AC}{AE}=\frac{10}{5}=2,\\\\\frac{AB}{AD}=\frac{8}{4}=2,\\\\\overline{AC}:\overline{AE}=\overline{AB}:\overline{AD}[/tex]

Since two corresponding legs/sides of triangle are in a constant proportion, the triangles must be similar from the SAS (Side-Angle-Side) Postulate.

Answer:

Suppose a problem of the form:

A person can choose:

1 out of 2 pants (red or blue)

1 out of 2 shirts (red or blue)

1 out of 2 pairs of shoes (red or blue)

1 out of 2 socks (red or blue)

1 out of 2 hats (red or blue)

Ok,

We have 5 selections with 2 options each, so the number of combinations is:

2^5

Now let's add another restriction, the person can not wear all red clothes, the person must have at least one blue one.

So we removed the combination where the person selects all red clothes, which means that we removed one combination.

So now, the total number of possible combinations is the number that we got before minus one:

2^5 - 1

Notice that subtracting the one is necessary, we first use the math that we know to find the total number of combinations and then we look at the restrictions to remove the restricted combination.

Then the complete problem is:

A person can choose:

1 out of 2 pants (red or blue)

1 out of 2 shirts (red or blue)

1 out of 2 pairs of shoes (red or blue)

1 out of 2 socks (red or blue)

1 out of 2 hats (red or blue)

And the person can not wear all red clothes, the person must have at least one blue one.

round 99.999 to the nearest number

=

100

According to the information we can infer that the number 99,999.999, when rounded to the nearest ones, is 100,000.

When rounding a number to the nearest ones, we look at the digit immediately to the right of the ones place. In this case, the digit is a 9. Since 9 is greater than or equal to 5, we round up the ones place. Therefore, the number 99,999.999 rounds to 100,000 when rounded to the nearest ones.

So, according to the information we can conclude that the number 99,999.999, when rounded to the nearest ones, is 100,000.

Answer:

  62.5 oz of 100%

Step-by-step explanation:

Let p represent the number of ounces of pure syrup. Then (100-p) is the number of ounces of 60% syrup. The amount of maple syrup in the desired mix is ...

  p +0.60(100 -p) = 0.85(100)

  0.40p +60 = 85 . . . . . . . . . . . simplify

  0.40p = 25 . . . . . . . . . . subtract 60

  p = 62.5 . . . . . . . . . divide by 0.4

62.5 ounces of pure syrup should be mixed with the diluted syrup to make 100 ounces of 85% maple syrup.

_____

The other 37.5 ounces will be 60% syrup.

Answer:

$10.08

Step-by-step explanation:

100%=$14

72%= x (cross multiple)

100% × x =72% × $14

100x =1008

divide both sides by 100

100x÷100=1008÷100

Step - by - Step Explanation :

A.) Between $1320 and $970

P(Z < 1300) - P(Z < 970)

find the Zscore of each scores and their corresponding probability uinag the standard distribution table :

P(Z < (x - μ) /σ) - P(Z < (x - μ) / σ))

P(Z < (1320 - 1250) /120) - P(Z < (970 - 1250) / 120))

P(Z < 0.5833) - P(Z < - 2.333)

0.7200 - 0.0098 = 0.7102 (Standard

=0.7102

B.)Under 1400

x = 1400

P(Z < 400)

P(Z < (x - μ) /σ)

P(Z < (1400 - 1250) /120)

P(Z < 1.25) = 0.8943

C.) Over 1290

P(Z > 1290)

P(Z < (x - μ) /σ)

P(Z > (1290 - 1250) /120 = 0.3333

P(Z > z) = 1 - P(Z < 0.3333) = P(Z < 0.3333) = 0.6304

P(Z > 0.3333) = 1 - 0.6304 = 0.3696

(4). 5 units down and a counterclockwise rotation of 90 degrees

Option D is the correct answer.

We need to find which options describe the transformations applied in the given figure.

There are four common types of transformations - translation, rotation, reflection, and dilation. From the definition of the transformation, we have a rotation about any point, reflection over any line, and translation along any vector. These are rigid transformations wherein the image is congruent to its pre-image. They are also known as isometric transformations. Dilation is performed at about any point and it is non-isometric.

From the given figure we can see 5 units down and a counterclockwise rotation of 90°.

Therefore, option D is the correct answer.

Answer:

116 degrees

Step-by-step explanation:

To find the answer, we must know what the sum of exterior angles are on a given shape, which is 360 degrees.

So, let's put the equation up.

8x-21+4x-13+5x-11+6x+14=360

Let's add all the x variables together to simplify it. And also add the number together too.

8x+4x+6x+5x= 23x

(-21)+(-13)+(-11)+14 = -31

The equation we have is in its initial simplified version. Let's simplify it even more to solve.

23x-31=360

Add 31 to both sides.

23x=391

Divide 23 on both sides to find x.

391/23 = x

x= 17

Let's put the value x in each exterior angle.

A= 8(17)-21 = 115 degrees

B= 6(17)+14 = 116 degrees

C= 5(17)-11 = 74 degrees

D= 4(17)-13 = 55 degrees

From the work above, we know B is the largest exterior angle, which is 116 degrees.
