Answer:
Regression models are predictive tools. If you want to use them to predict the behavior of an individual, you must set "behavior" as your dependent variable, and you must have indicators and measures for such. You must also identify your explanatory or independent variable likewise you must have indicators and measures for such.
If you have built your model on the basis of collected data, you will be able to predict the value of behavior given a value of the explanatory variable.

URGENT
Answer:
Step-by-step explanation:
You end up with a 30°-60°-90° triangle inside of △ABC.
The sides of a 30°-60°-90° triangle are always in the ratio 1:√3:2.
AB is opposite the 30° angle. AM is opposite the 90° angle and has length 10, so AB is half the length of AM.
AB = 5 units.

Leticia has two bouquets of flowers. Each bouquet contains 6 daisies. • Bouquet S contains 30 flowers. • Bouquet T contains 12 flowers. Which statement is true? The probability of randomly selecting a daisy from Bouquet Sis 50% The probability of randomly selecting a daisy from Bouquet Tis 20% The probability of randomly selecting a daisy from Bouquet S is equal to the probability of randomly selecting a daisy from Bouquet T. The probability of randomly selecting a daisy from Bouquet S is less than the probability of randomly selecting a daisy from Bouquet T. PLS HELP ASAP
Answer:
The probability of selecting a daisy from S is less than the probability of selecting a daisy from T.
Step-by-step explanation:
The probability of selecting a daisy from S is 6/30=20%.
The probability of selecting a daisy from T is 6/12=50%
The probability of selecting a daisy from S is not equal to the probability of selecting a daisy from T.
The probability of selecting a daisy from S is less than the probability of selecting one from T.
You are choosing between two health clubs. Club A offers membership fee of $16 plus a monthly fee of $23. Club B offers membership for a fee of $20 plus a monthly fee of $21. After how many months will the total cost of each health club be the same? What will be the total cost for each club?
Answer:
After five months, the total cost would be the same.
Step-by-step explanation:
You'd have to write equations for the price per month for each club.
Let
x
equal the number of months of membership, and
y
equal the total cost.
Club A's is
y
=
25
x
+
40
and Club B's is
y
=

.
Because we know that the prices,
y
, would be equal, we can set the two equations equal to each other.
25
x
+
40
=

x
+
15
. We can now solve for
x
by isolating the variable.

Assume that when adults with smartphones are randomly selected, 44% use them in meetings or classes. If 8 adult smartphone users are randomly selected, find the probability that exactly 2 of them use their smartphones in meetings or classes.
Answer: The probability is 0.448
Step-by-step explanation:
First, 44% of adults use their smartphones in meetings or classes, then the probability that a random adult uses their smartphone on a meeting is:
p = 0.44
Then the probability that a random adult do not use it is:
q = 1 - 0.44 = 0.66
If 8 adult smartphone users are randomly selected, find the probability that exactly 2 of them use their smartphones in meetings or classes.
For a random (and fixed) case, the probability will be equal to the product of the individual probabilities for each person, this leads to:
P = (0.44)*(0.44)*(0.66)*(0.66)*(0.66)*(0.66)*(0.66)*(0.66)
P = (0.44)²*(0.66)⁶ = 0.016
And now we need to consider the different combinations. If we have C combinations, then the probability for the event will be C*P.
Remember that if we have N elements, the total number of different groups of K elements (from these N elements) is:
[tex]C(N,K) = \frac{N!}{(N - K)!*K!}[/tex]
In this case, we have N = 8, and K = 2
Then we get:
[tex]C(8, 2) = \frac{8!}{(8 - 2)!*2!} = \frac{8!}{6!*2!} = \frac{8*7}{2} = 4*7 = 28[/tex]
Then there are 28 different combinations.
This means that the probability is:
Probability = 28*P = 28*0.016 = 0.448
Probability = 0.448

a bag contains 6 white marbles and 4 black marbles. a marble is drawn without replacing the first one. what is the probability of drawing a white marble on the first draw, followed by a white marble on the second?
Answer:
30/90 or 1/3
Step-by-step explanation:
This is because we know that 6+4=10. So we know the odds of drawing a white marble first is 6/10. And if we draw one without replacing it. This makes the second time 5/9 for white and 4/9 for black. We can then multiply 6/10 by 5/9 and get 30/90 which is equal to 1/3.
Hope this helps!

Find all points on the x-axis that are 14 units from the point (4, -7).
(Simplify your answer. Type an ordered pair. Use a comma to separate answers as needed.)
Answer:
The points are: (16.12,0),(-8.12,0).
Step-by-step explanation:
Solving a quadratic equation:
Given a second order polynomial expressed by the following equation:
[tex]ax^{2} + bx + c, a\neq0[/tex].
This polynomial has roots [tex]x_{1}, x_{2}[/tex] such that [tex]ax^{2} + bx + c = a(x - x_{1})*(x - x_{2})[/tex], given by the following formulas:
[tex]x_{1} = \frac{-b + \sqrt{\bigtriangleup}}{2*a}[/tex]
[tex]x_{2} = \frac{-b - \sqrt{\bigtriangleup}}{2*a}[/tex]
[tex]\bigtriangleup = b^{2} - 4ac[/tex]
Distance between two points:
Suppose we have two points, [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]. The distance between them is given by:
[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Find all points on the x-axis that are 14 units from the point (4, -7).
Being on the x-axis mean that they have y-coordinate equal to 0, so the point is (x,0).
The distance is 14. So
[tex]\sqrt{(x-4)^2+(0-(-7))^2} = 14[/tex]
[tex]\sqrt{x^2 - 8x + 16 + 49} = 14[/tex]
[tex]\sqrt{x^2 - 8x + 65} = 14[/tex]
[tex](\sqrt{x^2 - 8x + 65})^2 = 14^2[/tex]
[tex]x^2 - 8x + 65 - 196 = 0[/tex]
[tex]x^2 - 8x - 131 = 0[/tex]
So [tex]a = 1, b = -8, c = -131[/tex]
[tex]\bigtriangleup = (-8)^{2} - 4(1)(-131) = 588[/tex]
[tex]x_{1} = \frac{-(-8) + \sqrt{588}}{2} = 16.12[/tex]
[tex]x_{1} = \frac{-(-8) - \sqrt{588}}{2} = -8.12[/tex]
The points are: (16.12,0),(-8.12,0).

1. Jesse has a bottle that contains 1o liter
of water. He drinks 7 liter. Jesse says he
has liter left. Is he correct? Explain.
Answer:
Ok, so this is a word game, basically. The answer would be no, he is not correct BECAUSE...⬇
Step-by-step explanation:
It looks to be asking "Is Jesse correct in saying that he has EXACTLY one liter left?" That would be a no because even though 10L-7L= 3L, the problem asks if he does have exactly ONE liter left, and Jesse says he DOES. But, according to my little equation above, if he drank 7L, he would have 3L left, NOT 1L. Soo, my answer would be "No, Jesse is not correct because 10L-7L=3L and if he says there is 1L left, he would not be correct because there are 3L left." Hope that helps!

A community centre organises a raffle to raise money for charity.
There is 1 prize to be won in the raffle.
Daniel buys 17 raffle tickets.
A total of 280 tickets were sold.
Find the probability that Daniel does not win the prize?
Answer:
0.9393 = 93.93% probability that Daniel does not win the prize
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
In this question, we have that:
There are 280 tickets.
Daniel does not have 280 - 17 = 263 of them. So
263/280 = 0.9393
0.9393 = 93.93% probability that Daniel does not win the prize
The 24/7 Truck Rental Company has been charging an initial rental fee of $29 plus $2.50 per hour for rental of their small trucks. After a change in pricing policy, the new fee will be $19 up front plus $3.25 per hour. After how many hours of renting the truck will the new plan be more expensive than the old plan
Answer:
14 hours
Step-by-step explanation:
Old plan :
Initial fee =. $29
Hourly fee = $2.50
New plan :
Initial fee = $19
Hourly fee = 3.25
Let number of hours = x
When new plan will be more expensive than old plan :
19 + 3.25x > 29 + 2.50x
3.25x - 2.50x > 29 - 19
0.75x > 10
x > 10 / 0.75
x > 13.3333
After 14 hours
How many gallons of a 15% sugar solution must be mixed with a 5 gallons of a 40% solution to make a 20% solution
Answer:
20 gallons of 15% solution must be mixed with 5 gallons of 40% solution.
Step-by-step explanation:
40% of 5 gallons is 2 gallons of sugar
x represents the number of gallons of solution to be added.
15% of x is sugar.
The total amount of sugar must be equal to 20% of the final mixture.
The end mixture will be x + 5 gallons
Change percent to decimal for the equation:
.2(x +5) = .15x +2
.2x +1 = .15x +2
.2x - .15x = 2 -1
.05x = 1
x = 20
Check:
.2(20 +5) = .15(20) +2
.2(25) = 3 + 2
5 = 5 true
This means that adding 20 gallons of the 15% solution is adding 3 gallons of sugar [along with 17 gallons of water] to the 2 gallons of sugar in the original mixture.
20% of the 25 gallons, 5 gallons, of the final mixture is sugar. 80% [ 3+17 = 20 gallons] is water.
