The relationships that are most likely to be causal are:
A positive correlation between the number of homework assignments completed and the grade on the examA positive correlation between the temperature in a canyon in the early spring and the number of snakes seen by hikers.When are relationships causal?A relationship is causal when one variable has a direct effect on another variable. For example, the number of assignments completed would have an effect on the grade on an exam because as a students compeletes his assingment he becomes more familiar with the course.
Positive correlation means that the two variables have a positive relationship with each other. If one of the variable increases, the other vairable increases.

1 over 3 , 3 over 4 ,4 over 7 , 7 over 11, 11over 8 .... (i)one termof this sequence is p over q . Find the term of p and q , the next term in this sequence . Find the 6th term of this sequence 1).... 2).....
Answer:
Next term will be the 6th term i.e. a₆ will be:
a₆ = 14/11Here:
p = numerator = 14q = denominator = 11Step-by-step explanation:
Given the sequence
[tex]\frac{1}{3},\:\frac{3}{4},\:\frac{4}{7},\:\frac{7}{11},\:\frac{11}{8},...[/tex]
First of all the terms of the sequence are in p/q form, where p is the numerator and q is the denominator.
As the fifth term of the sequence is:
a₅ = 11/8
From the given sequence it is clear that the numerator is changing by 3 units and the denominator is also changing by 3 units.
Thus,
The next term will be the 6th term i.e. a₆ will be:
a₆ = 14/11Here:
p = numerator = 14q = denominator = 11What is the slope of a line that is parallel to this line (2,7) (5,-5)

Answer:
∆KAF, by rule LA
Step-by-step explanation:
The angle bisector divides angle FAP into two equal angles KAF and KAP. The two right triangles share side KA, so we have a leg KA and an angle KAF, KAP that are the same in the two triangles. That is enough to invoke rule LA (leg, angle) to claim congruence.
∆KAP ≅ ∆KAF by rule LA

Anything with the x value as zero is undefined.
Answer:
unidentified slope of 0
Step-by-step explanation:
Use the slope formula: [tex]\frac{y2-y1}{x2-x1}[/tex]
2 is y2, -3 is y1, 4 is x2, and 4 is x1.
[tex]\frac{2-(-3)}{4-4}[/tex]
[tex]\frac{2+3}{0}[/tex]
[tex]\frac{5}{0} =0[/tex]
The slope is 0. That means the slope is unidentified. I hope this helps!

Use the relationship between the angles in the figure to answer the question.
Which equation can be used to find the value of x?
x+49−28=180
x−49−28=180
x + 49 + 28 = 180
x + 28 = 180
Three lines making six angles with the top left angle at twenty eight degrees, the top right angled at forty nine degrees and the bottom middle angle at x degrees
Answer:
x + 49 + 28 = 180
Step-by-step explanation:
The angles on a straight line with x° are 28° and 49° respectively, side by side with x°. This is because, vertical angles are equal. Therefore, the angle vertically opposite 28° and 49° are equal to 28° and 49° respectively.
Therefore, since angles on a straight line is 180°, thus:
x + 49 + 28 = 180
Answer:
x + 49 + 28 = 180

Jeremy is making a healthy ice cream using only ripe bananas and peanut butter, the recipe makes 4 servings and calls for a ratio of 5
bananas to 3 tablespoons of peanut butter if Jeremy has 30 bananas, how many tablespoons of peanut butter does he need
Tablespoons
Answer:
can u show me a pic of the question so it is easier
The healthy ice cream Jeremy is making has 30 bananas and requires 18 tablespoons of peanut butter.
What is a ratio?The ratio describes the amount of quantity in simplest form, a:b can be written as 'a/b' for convenience.
Given the healthy ice cream, Jeremy is making requires 5 bananas and 3 tablespoons of peanut butter.
From the given question itself, we can conclude that bananas and peanut butter are in direct proportion as the increase in one quantity will result in an increase of another quantity and we can write this in proportion and let the no. of tablespoons of peanut butter requires for 30 banans is x.
∴ 5 : 3 : : 30 : x.
Or
5/3 = 30/x.
5x = 90.
x = 18.
So, Jeremy needs 18 tablespoons of peanut butter for the 30 bananas he has.
