Does Red Increase Men’s Attraction to Women? A study1 examines the impact of the color red on how attractive men perceive women to be. In the study, men were randomly divided into two groups and were asked to rate the attractiveness of women on a scale of 1 (not at all attractive) to 9 (extremely attractive). Men in one group were shown pictures of women on a white background while the men in the other group were shown the same pictures of women on a red background. The results are shown in Table 1 and the data for both groups are reasonably symmetric with no outliers. Color n x¯ s Red 15 7.2 0.6 White 12 6.1 0.4 Table 1 Does red increase men’s attraction to women?

Someone explain to me how to do this

Answers

Answer:

  14.9 cm

Step-by-step explanation:

The side of interest is opposite an angle that is not marked. You find the value of that angle by making use of the fact that the sum of angles of a triangle is 180°.

  C = 180° -150° -12° = 18°

Now, fill in the available information in the given formula for the Law of Sines and solve for c:

  sin(B)/b = sin(C)/c

  sin(12°)/(10 cm) = sin(18°)/c

Cross multiply:

  c·sin(12°) = (10 cm)·sin(18°)

Divide by the coefficient of c:

  c = (10 cm)·sin(18°)/sin(12°) ≈ 14.9 cm

The difference between twice an angle's measure and it's supplement is 27. find the measure of the angle

Answers

 

x and y  are supplementary angles

x - y = 27

x + y = 180

--------------------- We add the equations:

2x   / = 207

2x = 207

x = 207/2

x = 103.5° = 103° : 30 miny = 180° - 103.5° = 76.5° = 76° : 30min

Final answer:

To find the angle measure, set up the equation 2x - (180 - x) = 27, simplify to 3x = 207, and solve to find that x = 69 degrees.

Explanation:

The question asks to find the measure of an angle where the difference between twice the angle's measure and its supplement is 27. To solve this, let's designate the measure of the angle as x. Since the angle's supplement will be 180° - x, we can set up the equation 2x - (180° - x) = 27. Simplifying this equation, we get 2x - 180° + x = 27, which simplifies further to 3x = 207°. Dividing both sides of the equation by 3, we find that x = 69°. Therefore, the measure of the angle is 69 degrees.

A tree casts a shadow of 24 feet at the same time as a 5-foot tall man casts a shadow of 4 feet. Find the height of the tree. Note that the two triangles are proportional to one another.

Answers

Answer:

30 ft

Step-by-step explanation:

Let the height of the tree be x ft. There are two right triangles:

1. Tree and its shadow are two legs of the first triangle;

2. Man and his shadow are two legs of the second triangle.

A tree casts a shadow of 24 feet at the same time as a 5-foot tall man casts a shadow of 4 feet. This means these two triangle are similar. Similar triangles have proportional sides' lengths. Hence,

[tex]\dfrac{\text{tree}}{\text{tree shadow}}=\dfrac{\text{man}}{\text{man's shadow}}\\ \\\dfrac{x}{24}=\dfrac{5}{4}\\ \\4\cdot x=5\cdot 24\\ \\x=\dfrac{5\cdot 24}{4}=5\cdot 6=30\ ft[/tex]

Answer:

30 feet

Step-by-step explanation:

We are given that a tree casts a shadow of 24 feet at the same time as a 5-foot tall man casts a shadow of 4 feet.

We are to find the height of the tree.

Using their proportions to compare the height of each object to the length of the shadow.

[tex]\frac{h}{24} =\frac{5}{4}[/tex]

[tex]h=\frac{5\times24}{4}[/tex]

[tex]h=30[/tex]

Therefore, the height of the tree is proportion comparing the height of each object to the length of the shadow 30 feet.

If $75 is invested at an interest rate of 8% per year and is compounded monthly, how much money is in the account in 15 years?

Answers

Answer:

$248.03

Step-by-step explanation:

The formula you use for this is as follows:

[tex]A(t)=P(1+\frac{r}{n})^{nt}[/tex]

where A(t) is the amount after the compounding is done, P is the initial amount invested, r is the interest rate in decimal form, n is the number of times the compounding is done per year, and t is the time in years.  Using that information and filling in our equation gives us this:

[tex]A(t)=75(1+\frac{.08}{12})^{(12)(15)}[/tex]

which simplifies down to

[tex]A(t)=75(1+.0066667)^{180}[/tex]

which simplifies further to

[tex]A(t)=75(3.307118585)[/tex]

which multiplies to $248.0338938.  Round to the nearest cent to get your answer.

The amount of money is $248.02.

Principal amount = P=75

Interest rate = r = 8% = 0.08

Number of years = t = 15

Number of times compounded in a year = n = 12

A = Amount after t years.

After 15 years there will be:

[tex]A=P\left(1+\frac{r}{n}\right)^{nt}\\ A=75\left(1+\frac{0.08}{12}\right)^{\left(12\cdot15\right)}\\ A=248.019110806\\ A \approx 248.02[/tex]

Answers

Answer:

Part 1) The measure of arc EHL is [tex]108\°[/tex]

Part 2) The measure of angle LVE is [tex]54\°[/tex]

Step-by-step explanation:

step 1

Let

x-----> the measure of arc EHL

y----> the measure of arc EVL

we know that

The measurement of the outer angle is the semi-difference of the arcs it encompasses.

so

[tex]m<EYL=\frac{1}{2}(y-x)[/tex]

we have

[tex]m<EYL=72\°[/tex]

substitute

[tex]72\°=\frac{1}{2}(y-x)[/tex]

[tex]144\°=(y-x)[/tex]

[tex]y=144\°+x[/tex] ------> equation A

Remember that

[tex]x+y=360\°[/tex] -----> equation B ( complete circle)

substitute equation A in equation B and solve for x

[tex]x+(144\°+x)=360\°[/tex]

[tex]2x=360\°-144\°[/tex]

[tex]x=216\°/2=108\°[/tex]

Find the value of y

[tex]y=144\°+x[/tex]

[tex]y=144\°+108\°=252\°[/tex]

therefore

The measure of arc EHL is [tex]108\°[/tex]

The measure of arc EVL is [tex]252\°[/tex]

step 2

Find the measure of angle LVE

we know that

The inscribed angle measures half that of the arc comprising

Let

x-----> the measure of arc EHL

[tex]m<LVE=\frac{1}{2}(x)[/tex]

we have

[tex]x=108\°[/tex]

substitute

[tex]m<LVE=\frac{1}{2}(108\°)=54\°[/tex]

Jay on started off his penny collection with 1 penny. He then adds 5 pennies to his collection each day. How could you change the above scenario to make it a geometric series rather than an arithmetic series?

Answers

Answer:

By doubling each day

Step-by-step explanation:

Jay is increasing  daily a fixed amount of pennies to his collection.  That's an arithmetic series, because to obtain the next term you have to do an addition.

To get a geometric series or progression you have to find the next term through multiplication.

So, if he wants to convert his series into a geometric series, he'd have to double his contribution to his collection each day (as an example).

How do you use the digits in a hundredths decimal to write a percent?

Answers

Explanation:

"Percent" literally means "per hundred" or "divided by 100". The percent symbol (%) is a shorthand way to write /100 ("divided by 100," or "hundredths"). So, hundredths and percent are essentially the same thing.

Given a "hundredths decimal", move the decimal point 2 places to the right and add a % symbol. (Moving the decimal point multiplies the number by 100; adding the % symbol divides it by 100, so the end result is the same value written in a different form.)

Example:

  19% = 19/100 = 0.19 . . . . (nineteen percent = nineteen hundredths)

and in the other direction, ...

  0.53 = 53/100 = 53% . . . . (fifty-three hundredths = fifty-three percent)

Answer:

You need 20 liters of 20% acid solution. You have jugs of 10% solution and 25% solution. How many liters of each should you combine to get the needed solution?

Answers

Answer:

6.(6) and 13.(3) liters.

Step-by-step explanation (this way is not the shortest one):

1. the basic rule is: the mas/volume of pure substance after and before combination is the same.

2. There is 4 liters of pure substance in 20*0.2 acid solution (20*0.2=4);

3. if 'x' is the volume of pure substance in 10%-solution; and if 'y' is the volume of pure substance in 20%-solution, then their sum of volumes is 4. It means, x+y=4 - this is the 1-st equation for system.

4. the volume of 10%-solution is x/0.1=10x; the volume of 20%-solution is y/0.25=4y; their sum is 20 litres. It means, 10x+4y=20 - this is the 2-d equation of the system.

5. to calculate the volumes of the pure substance:

[tex]\left \{ {{x+y=4} \atop {10x+4y=20}} \right.  \ =>\ \left \{ {{x=\frac{2}{3} } \atop {y=\frac{10}{3} }} \right.[/tex]
