Answer:
This correlation simply means that, in every twin whether identical or fraternal twins, there is a relation between their IQ scores and when they are raised together.
Regarding to the test carried out, it showed that, when an identical twin is raised together, their IQ score tends to be higher in direct comparison with a fraternal twin that was raised together. That is, if the fraternal twin IQ is 100, then, the identical twin IQ is going to be above 100 (probably around 120)

Write an equation that models this problem: Trevor paid$528 to stay at the MGM Grand Hotel in Las Vegas for four nights over New Year's weekend. What was the rate,r, per day to stay at the MGM Grand for New Year's?
Answer:
r = $105.6
Step-by-step explanation:
Given,
Amount paid by Trevor for 4 nights = $528
Rate per day = r
Now,
We know that a 4-night stay in the hotel means 5 days to stay at MGM Grand.
Now,
Amount paid = Number of days x Rate per day
$528 = 5 r
[tex]r = \frac{528}{5}[/tex]
r = $105.6
Hence, Trevor pays $105.6 to stay at the MGM Grand Hotel in Las Vegas for four nights.

Which expression is a factor of 9x - 18x + 8. 3x - 4 3x, +4 3x +4, or 3x -8?
Answer: 3x-8
Step-by-step explanation:
The algebraic factor of the given quadratic equation 9x² - 18x + 8 is 3x - 4 thus option (A) is correct.
What is an algebraic factor?An algebraic factor is the multiplication of two algebraic terms.
If we divide an algebraic factor by a factor that is available inside then the remainder after the division will be zero.
As per the given quadratic equation,
9x² - 18x + 8
⇒ 9x² - 12x - 6x + 8
⇒ 3x(3x - 4) - 2(3x - 4)
⇒(3x - 4)(3x - 2)
Hence "The algebraic factor of the given quadratic equation 9x² - 18x + 8 is 3x - 4".

A skier is on the top of a 350 meter tall mountain looking down at a tree. The direct path from the tree to the skier is 505 meters. What is the angle of depression from where the skier is standing to the base of the tree
Answer:
[tex]43.87^{\circ}[/tex]
Step-by-step explanation:
We are given that
Height of mountain=350 m
Distance from the tree to the skier=505 m
We have to find the angle of depression from where the skier is standing to the base of the tree.
In triangle ABC
[tex]\frac{AB}{AC}=sin\theta[/tex]
By using the formula
[tex]\frac{Perpendicular\;side}{Hypotenuse}=sin\theta[/tex]
[tex]\frac{350}{505}=sin\theta[/tex]
[tex]sin^{-1}(\frac{350}{505})=\theta[/tex]
[tex]\theta=43.87^{\circ}[/tex]
Hence, the angle of depression from where the skier is standing to the base of the tree=[tex]43.87^{\circ}[/tex]
What is the measure of AngleDEF?

Step 1: Define
[tex]\displaystyle \frac{a}{-7} - 7 = 5[/tex]
Step 2: Solve for a
Addition Property of Equality: [tex]\displaystyle \frac{a}{-7} - 7 + 7 = 5 + 7[/tex] [Simplify] Add: [tex]\displaystyle \frac{a}{-7}= 12[/tex]Multiplication Property of Equality: [tex]\displaystyle -7 \cdot \frac{a}{-7} = 12 \cdot -7[/tex][Simplify] Multiply: [tex]\displaystyle a = -84[/tex]Step 3: Check
Plug in a into the original equation to verify it's a solution.
Substitute in a: [tex]\displaystyle \frac{-84}{-7} - 7 = 5[/tex][Frac] Divide: [tex]\displaystyle 12 - 7 = 5[/tex]Subtract: [tex]\displaystyle 5 = 5[/tex]Here we see that 5 does indeed equal 5.
∴ a = -84 is the solution to the equation.
5x -7 + 2x = 4x + 5
Answer:
x = 4
Step-by-step explanation:
5x -7 + 2x = 4x + 5
Combine like terms
5x + 2x -7 = 4x + 5
7x - 7 = 4x + 5
Combine like terms again
-4x + 7x - 7 = 4x - 4x + 5
3x - 7 = 5
3x = 5 + 7
3x = 12
Divide by 3 both sides
3x/3 = 12/3
x = 4
Hope this helps!! :)

At a meeting, 9 football players were there. If this is 30% of the football players, what is the total amount of football players on the team?
Answer: 30 player on the team
Step-by-step explanation:
If 9 players = 30% of the team then 3 = 10% of the team. With this information you can multiply 10 x 10 to get 100(%) and then multiply 3 x 10 to get 30(players). This may not be how you are supposed to solve this problem but oh well.

TJ makes a salary of $400 a week. He also
makes a commission of 15% off of
everything he sells for the week. If his total
sales are $15,000, what is his total pay for
the week?
Answer:
Step-by-step explanation:
If TJ made 15,000 dollars in a week, with the 15% commission,
15,000*15/100=2,250 in commission
2250+400=2650 salary for that week
