A magazine has 1,620,000 subscribers, of whom 640,000 are women and 980,000 are men. Thirty percent of the women read the advert

Kaylis [27]

Answer:

Expected number of subscribers in the sample who read the advertisements=42

Step-by-step explanation:

Step 1

Determine the proportion of both men and women subscribers as shown;

Proportion of Men subscribers=number of men subscribers/total number of subscribers

where;

number of men subscribers=980,000

total number of subscribers=number of men+number of women

total number of subscribers=(980,000+640,000)=1,620,000

replacing;

proportion of men subscribers=980,000/1,620,000=98/162

Step 2

Proportion of women subscribers=1-(98/162)=64/162

Step 3

Expected proportion of men that read the advertisement=(50/100)×(98/162)=4,900/16,200=49/162

Expected proportion of women that read the advertisement=(30/100)×(64/162)=1,920/16,200=192/1620

Step 4

Total number of proportion=(49/162)+(192/1620)=341/810

Expected number from the sample=(341/810)×100=42

Expected number of subscribers in the sample who read the advertisements=42

Can someone please answer my trigonometry problem? I've been trying to get answers all day for something so minimal.

Fantom [35]

Answer:

∠B ≈ 30.0°

Step-by-step explanation:

The law of sines can be used to solve a triangle when two sides and an angle opposite one of them are given.

sin(B)/b = sin(C)/c

sin(B) = (b/c)sin(C) . . . . solve for sin(B)

sin(B) = (14/28)sin(91°) ≈ 0.49992385

The angle is found using the inverse sine function:

B = arcsin(0.49992384) ≈ 29.99496°

Rounded to tenths, the angle is ...

m∠B ≈ 30.0°

_____

<em>Additional comments</em>

Many triangle solver apps and web sites are available if all you want is an answer.

When using your calculator, be sure the angle mode is set to "degrees."

The Law of Sines can also be used to solve a triangle when two angles and one side are known.

What number should be added to both sides of the equation to complete the square? x2 + 3x = 6

Nookie1986 [14]

Answer:

2.25

Step-by-step explanation:

x^2 + 3x =6

Take the coefficient of the x term

Divide by 2

3/2 = 1.5

Square it

1.5^2 =2.25

Add this to both sides of the equation

Answer:

$FH=73$

Step-by-step explanation:

We are given that a segment FH and G is the midpoint of FH.

FH= $14x-4$

$FG=5x+9$

We have to find the measure of FH.

When G is the midpoint of segment FH

Then , FG=GH

$FH=FG+GH$

Segment addition property

$14x-4=FG+FG$

Substitution property

$14x-4=2FG$

$14x-4=2(5x+9)$

$14x-4=10x+18$

$14x-10x=18+4$

$4x=22$

$x=\frac{22}{4}=5.5$

Substitute the values then we get

$FG=5(5.5)+9=36.5$

$FG=GH=36.5$

$FH=14(5.5)-4=73$
