Answer:

30

Step-by-step explanation:

18 / 3 = 6

6 x 2 = 12

18 + 12 = 30

Answer:

[tex]P(F) = 0.515[/tex]

[tex]P(M) = 0.485[/tex]

Step-by-step explanation:

Given

[tex]Female = 51.5\%[/tex]

Solving (a): Probability of running into a female

To do this, we simply convert the given proportion to decimal

[tex]P(F) = 51.5\%[/tex]

Convert to fraction

[tex]P(F) = \frac{51.5}{100}[/tex]

[tex]P(F) = 0.515[/tex]

Solving (b): Probability of running into a male

Represent this with [tex]P(M)[/tex]

To solve this, we apply the concept of probability complement which states that:

[tex]p + q = 1[/tex]

In this case:

[tex]P(F) + P(M) = 1[/tex]

Substitute 0.515 for P(F)

[tex]0.515 + P(M) = 1[/tex]

Subtract 0.515 from both sides

[tex]0.515-0.515 + P(M) = 1 - 0.515[/tex]

[tex]P(M) = 1 - 0.515[/tex]

[tex]P(M) = 0.485[/tex]

Answer:

x = 8

Step-by-step explanation:

Two tangent segments to a circle from the same external point are congruent, thus

WP = WQ , that is

3x - 6 = x + 10 ( subtract x from both sides )

2x - 6 = 10 ( add 6 to both sides )

2x = 16 ( divide both sides by 2 )

x = 8

Answer:

answer is a but please mark me brainliest if I m correct

Answer:

(8, - 3 )

Step-by-step explanation:

Given the 2 equations

x - y = 11 → (1)

3x + 10y = - 6 → (2)

Multiplying (1) by 10 and adding to (2) will eliminate the y- term

10x - 10y = 110 → (3)

Add (2) and (3) term by term to eliminate y

13x + 0 = 104

13x = 104 ( divide both sides by 13 )

x = 8

Substitute x = 8 into either of the 2 equations and solve for y

Substituting into (2)

3(8) + 10y = - 6

24 + 10y = - 6 ( subtract 24 from both sides )

10y = - 30 ( divide both sides by 10 )

y = - 3

solution is (8, - 3 )

Answer:

6 Hours

Step-by-step explanation:

Q. A car wash can wash four cars in one hour. The table shows the total number of cars washed. How long will it take to wash 24 cars?

A. 4 Cars = 1 Hour

   8 Cars = 2 Hours

   12 Cars = 3 Hours

   16 Cars = 4 Hours

   20 Cars = 5 Hours

   24 Cars = 6 Hours

Hope this helps

Answer:

A real solution in algebra is simply a solution to an equation that is a real number.

for example

If y>0, then x2 = y has two real solution or roots. x = ±√y

If y=0, then x2 = y has one real solution.

Answer:

210 students

Step-by-step explanation:

80 students chose the aquarium.

60 students chose the science center.

30 students chose the planetarium.

40 students chose the farm.

The students can't vote for more than one place, so you just add all the numbers together.

80 + 60 + 30 + 40 = 210 students

Answer:

120°

Step-by-step explanation:

A sector of a circle is the portion or region of a circle enclosed by two radii and an arc. The perimeter of a the sector of a circle is given by the formula:

Perimeter of sector = [tex]\frac{\theta}{360} *2\pi r[/tex] + 2r

Where θ is the angle which forms the sector and r is the radius of the circle.

Given that Perimeter of sector = 57.32 cm, radius (r) = 14 cm, we can find the angle θ using:

Perimeter of sector = [tex]\frac{\theta}{360} *2\pi r[/tex] + 2r

[tex]57.32=\frac{\theta}{360} *2\pi *14+2(14)\\\\57.32-28=\frac{\theta}{360} *2\pi *14\\\\29.32=\frac{\theta}{360} *2\pi *14\\\\ \frac{\theta}{360}=\frac{29.32}{2\pi *14} \\\\\frac{\theta}{360}=0.33\\\\\theta=120^o[/tex]

Answer:

125 deg

Step-by-step explanation:

(n - 2)180

n = 7

(7 - 2)180 = 5(180) = 900

900 - 135 - 129 - 129 - 127 - 131 - 124 = 125
