A) complete the table (use 4 decimal places when applicable)
B) what percent of the people have exactly one sibling ?

Answer:

Your required answer is option is {20}.

Step-by-step explanation:

Hey, there!!

The reason for above answer is we generally find intersections among the sets by extracting the common elements of the sets.

Here,

R = {10,15,20}

S = {20,25}.

Now, 20 is common im both so,

R intersection S = {20}.

The value of k = 20.

We have the following expression -

[tex]\frac{2}{3} (6k-30)+k=100[/tex]

We have to find the value of K.

We have -

[tex]$log(2)^{z} = \pi[/tex]

z x log(2) = π

z = [tex]$\frac{\pi }{log\;2}[/tex]

z = 10.43

According to the question, we have -

[tex]\frac{2}{3} (6k-30)+k=100[/tex]

[tex]\frac{2}{3}\times 6[/tex](k - 5) + k = 100

4(k - 5) + k = 100

4k - 20 + k = 100

6k = 120

k = 20

Hence, the value of k = 20

Answer:

Step-by-step explanation:

Let be [tex]f(x) = \frac{1}{8\cdot x}\cdot \ln(2\cdot x) -7[/tex], the first and second derivatives of the function are, respectively:

[tex]f'(x) = \frac{\left(\frac{2}{2\cdot x}\right)\cdot 8\cdot x-8\cdot \ln (2\cdot x) }{64\cdot x^{2}}[/tex]

[tex]f'(x) = \frac{8-8\cdot \ln (2\cdot x)}{64\cdot x^{2}}[/tex]

[tex]f'(x) = \frac{1-\ln(2\cdot x)}{8\cdot x^{2}}[/tex]

[tex]f''(x) = \frac{\left(-\frac{2}{2\cdot x} \right)\cdot (8\cdot x^{2})-[1-\ln(2\cdot x)]\cdot (16\cdot x)}{64\cdot x^{4}}[/tex]

[tex]f''(x) = \frac{-8\cdot x-16\cdot x+16\cdot x\cdot \ln (2\cdot x)}{64\cdot x^{4}}[/tex]

[tex]f''(x) = \frac{-24\cdot x+16\cdot x \cdot \ln (2\cdot x)}{64\cdot x^{4}}[/tex]

[tex]f''(x) = -\frac{3}{8\cdot x^{3}}+\frac{\ln (2\cdot x)}{4\cdot x^{3}}[/tex]

Now, let equalise the first derivative to zero and solve the resulting expression:

[tex]\frac{1-\ln(2\cdot x)}{8\cdot x^{2}} = 0[/tex]

[tex]1-\ln(2\cdot x) = 0[/tex]

[tex]\ln(2\cdot x) = 1[/tex]

[tex]\ln 2 +\ln x = 1[/tex]

[tex]\ln x = 1-\ln 2[/tex]

[tex]x = e^{1-\ln 2}[/tex]

[tex]x = \frac{e}{e^{\ln 2}}[/tex]

[tex]x = \frac{e}{2}[/tex]

[tex]x \approx 1.359[/tex]

This result is evaluated at the second derivative expression:

[tex]f''(1.359) =-\frac{3}{8\cdot (1.359)^{3}}+\frac{\ln [2\cdot (1.359)]}{4\cdot (1.359)^{3}}[/tex]

[tex]f''(1.359)\approx -0.050[/tex]

The critical value leads to a critical maximum and there are two intervals:

[tex](0, 1.359)[/tex] - Increasing

[tex](1.359,+\infty )[/tex] - Decreasing

Answer:

17 ft

Step-by-step explanation:

the area of a square is length x length, or [tex]length^{2}[/tex]

so, since you already have the area, do the opposite of squaring it, which is finding the square root.

[tex]\sqrt{289}[/tex] = 17

The length of each side of a square is   [tex]17 feet[/tex]  whose area is  [tex]289 ft sq[/tex]. (mentioned in the question).

A square is a four-sided figure in which all sides are equal in length and the measure of each angle is [tex]90^0[/tex]. The area is defined as the space that is contained inside the closed boundary or perimeter or circumference.

We know that the

area of the square = [tex]side \times side[/tex]

[tex]289 ft sq[/tex]     [tex]= side \times side[/tex]

[tex]289 = (side) ^2[/tex]

[tex]\sqrt{289 } = side[/tex]

[tex]17 = side[/tex]

Thus, the length of each side of a square consisting of an area of[tex]289 ft sq[/tex] is [tex]17 feet[/tex]  .

Answer:

Step-by-step explanation:

Since ∠3 and ∠4 are supplementary it means the the sum of their angles is equal to 180°

To find the angles add both ∠3 and ∠4 and equate it to 180° solve for x and substitute it into their various expressions

That's

∠3 + ∠4 = 180

5x + 22 + 7x + 2 = 180

12x + 24 = 180°

12x = 180 - 24

12x = 156

Divide both sides by 12

x = 13

So for ∠3

∠3 = 5x + 22

∠3 = 5(13) + 22

= 65 + 22

∠3 = 87°

For ∠4

∠4 = 7x + 2

∠4 = 7(13) + 2

= 91 + 2

∠4 = 93°

Hope this helps you

Answer:

[tex] \boxed{ \bold{ \boxed{ \sf{ m \: ∠ \: 3 = 87 °}}}}[/tex]

[tex] \boxed{ \bold{\boxed{ \sf{m \: ∠4 = 93 °}}}}[/tex]

Step-by-step explanation:

We know that the sum of supplementary angle adds up to 180 °

So,

[tex] \sf{5x + 22 + 7x + 2 = 180°}[/tex]

Collect like terms

⇒[tex] \sf{12x + 22 + 2 = 180°}[/tex]

Add the numbers

⇒[tex] \sf{12x + 24 = 180°}[/tex]

Move 24 to right hand side and change it's sign

⇒[tex] \sf{12x = 180 - 24}[/tex]

Subtract 24 from 180

⇒[tex] \sf{12x = 156}[/tex]

Divide both sides of the equation by 12

⇒[tex] \sf{ \frac{12x}{12} = \frac{156}{12} }[/tex]

Calculate

⇒[tex] \sf{x = 13}[/tex]

Value of x = 13

Now, substituting / Replacing the value of x

[tex] \sf{m ∠ 3 = 5x + 22}[/tex]

⇒[tex] \sf{ m \: ∠ \: 3 = 5 \times 13 + 22}[/tex]

⇒[tex] \sf{m \: ∠ \: 3 = 65 + 22}[/tex]

⇒[tex] \sf{ \: m \: ∠ \: 3 = 87}[/tex]

Again,

[tex] \sf{ \: m \: ∠ \: 4 = 7x + 2 }[/tex]

⇒[tex] \sf{m \: ∠ \: 4 = 7 \times 13 + 2}[/tex]

⇒[tex] \sf{ \: m \: ∠ \: 4 \: = 91 + 2 }[/tex]

⇒[tex] \sf{m \: ∠ \: 4 = 93 }[/tex]

m ∠ 3 = 87

m ∠ 4 = 93

  (A, B, C) = (8, 17, 23) inches

Step-by-step explanation:

We can let A, B, and C represent the corresponding side lengths. Then we are given ...

  A + B + C = 48 . . . . . . the perimeter is 48 inches

  B = A + 9 . . . . . . . . . . . B is 9 inches longer than A

  C = 2A +7 . . . . . . . . . . the base (remaining side) is 7 inches more than ...

Substituting for B and C in the first equation, we have ...

  A + (A+9) +(2A+7) = 48

  4A = 32 . . . . . . . . . . . . . . collect terms, subtract 16

  A = 8

  B = A+9 = 17

Answer:

11481.4875 km

Step-by-step explanation:

Given the that :

Galapagos island and Island of Naura are on the equator

Galapagos = 90.30°W

Island of Naura = 166.56°E

Ensuring same bearing is used for both :

Island of Naura = 166.56°E = (360° - 166.56°) = 193.44°W

Hence, we can calculate the difference in the bearing of both locations :

(193.44 - 90.30)°W = 103.14°

Hence the distance between Galapagos and Island of Naura along the equator is :

(Difference in bearing / total bearing) * earth's Circumference

Earth's Circumference = 40,075km

(103.14 / 360) × 40,075

0.2865 × 40,075

= 11481.4875 km

Step-by-step explanation:

Let company has total x employees.

[tex]29.8 \% \: of \: x = 29700 \\ \\ 0.298x = 29700 \\ \\ x = \frac{29700}{0.298} \\ \\ x = 99,664.4295 \\ \\ x \approx \: 99,664 \: [/tex]

Answer:  99,664 employees in total

Step-by-step explanation:

So if 29.8% of the total people is 29,700  people then we could represent that by the equation.

29.8% * x = 29,700  where x is the total people.

0.298 * x = 29,700

0.298x = 29,700

 x = 99,664.429  

Rounded to the nearest whole number is 99,664
