Answer:

x=-6

Step-by-step explanation:

2/3x+5=1

Subtract 5 from both sides:

2/3x=-4

Multiply both sides by 3:

2x=-12

Divide both sides by 2:

x=-6

Hope this helps!

Answer:

-6

Step-by-step explanation:

2/3x +5 = 1

        -5    -5

2/3x = -4

2/3x/2/3 = -4/2/3

= -6

Answer:

Inverse.

Step-by-step explanation:

Inverse trigonometric functions.

e. g. tan-1 x means 'the angle whose tangent is x'.

They are also called arcsin, arccos and arctan.

Answer:

option B

Step-by-step explanation:

[tex]P(x =x) [{\frac{1}{6} ;x =1,2,3...6][/tex]

[tex]E (x) = \frac{6+1}{2} =\frac{7}{2} =3.5\\\\E(x)=3.5[/tex]

Given random experiment of tossing of 6 sided dice is follow above distribution

Therefore, suppose x₁, x₂ ...x₁₀ are 10 independent and indentical random variable which represent first 10 rolls

Average of first 10 rows equals

[tex]\bar x_1 =\frac{ \sum ^{10}_{i=1}xi}{10}[/tex]

[tex]E(\bar x_1)=\frac{ \sum ^{10}_{i=1}E(x_1)}{10} \\\\=\frac{10(3.5)}{10} \\\\=3.5\\\\E(\bar x_1) = 3.5----(1)[/tex]

now suppose ,

x₁₁,x₁₂, ...x₁₅ are 5 independent and identical random variable which represent last 5 roll

average of last 5 roll is

[tex]E(\bar x_2)= \frac{ \sum ^{5}_{i=1}xi}{5} \\\\= \frac{5 \times(3.5)}{5} \\\\=3.5[/tex]

Therefore,[tex]\bar x_1 - \bar x_2[/tex]

3.5 - 3.5 = 0

The mean [tex]\mu(\bar{x_1}-\bar{x_2})[/tex]  of the sampling distribution of the difference in sample means [tex](\bar{x_1}-\bar{x_2})[/tex] is 0 and this can be determined by using the formula of the average mean.

Given:

The average mean of the first ten rolls is given by the formula:

[tex]\rm E(\bar{x_1}) = \dfrac{\sum^{10}_{i=1}(x_1)}{10}[/tex]

Now, put the values of known terms in the above equation.

[tex]\rm E(\bar{x_1})=\dfrac{10\times 3.5}{10}[/tex]

[tex]\rm E(\bar{x_1})={3.5}[/tex]

The average mean of the remaining five rolls is given by the formula:

[tex]\rm E(\bar{x_2}) = \dfrac{\sum^{5}_{i=1}(x_i)}{5}[/tex]

Now, put the values of known terms in the above equation.

[tex]\rm E(\bar{x_1})=\dfrac{5\times 3.5}{5}[/tex]

[tex]\rm E(\bar{x_1})={3.5}[/tex]

Now, [tex](\bar{x_1}-\bar{x_2}) = 3.5 - 3.5 = 0[/tex].

The mean [tex]\mu(\bar{x_1}-\bar{x_2})[/tex]  of the sampling distribution of the difference in sample means [tex](\bar{x_1}-\bar{x_2})[/tex] is 0.

Step-by-step explanation:

If you FOIL these factors, you get the give quadratic polynomial. x×x = x^2 4×5 = 20. 4x + 5x = 9x

Answer:

y = x2 + x - 20 factors into

y = (x +5) * (x -4)

Step-by-step explanation:

Answer:

y = (x + 5)(x - 4)

Step-by-step explanation:

Given

y = x² + x - 20

Consider the factors of the constant term (- 20) which sum to give the coefficient of the x- term (+ 1)

The factors are + 5 and - 4, since

5 × - 4 = - 20 and 5 - 4 = + 1, thus

x² + x - 20 = (x + 5)(x - 4)

Answer:

volume = 11,664 units cubed

Step-by-step explanation:

2[tex]x^{2}[/tex] times 3 = bottom and sides

[tex]x^{2}[/tex] times 2 = ends

A = 6[tex]x^{2}[/tex] + 2[tex]x^{2}[/tex] = 8[tex]x^{2}[/tex]

2592 = A

2592/8 = 8[tex]x^{2}[/tex]/8

324 = [tex]x^{2}[/tex]

take square root of both sides

18 = x

so volume = length times width times height

2(18) times 18 times 18 = 11664

11664 units cubed

Answer:

209

Step-by-step explanation:

The volume of the cone, to the nearest cubic millimeters is: C. 209 mm³.

Volume of a cone = 1/3πr²h

Where, r = radius of the cone, and h = height of the cone.

Given:

Thus:

Volume of a cone = 1/3(3.14)(5²)(8)

Volume of a cone = 209 mm³

Thus, the volume of the cone, to the nearest cubic millimeters is: C. 209 mm³.

The formula for circumference is C = 2[tex]\pi[/tex]r. When plugging in these values, 2 x 3.14 x 4.5 is equal to 28.26.

Circumference of her garden is 28.26 m. So, Option 'A' is the correct answer to the following question.

What information do we have?

Radius of circular garden = 4.5 m

Circumference of her garden = circumference of circle
