Which scatterplot has a correlation coefficient closest to r = –1?
A coefficient of r = -1 is a negative so the dots would move downward as they move to the right ( higher dots are on the left side, lower dots on the right side. As the coefficient gets closer to -1 the dots form more of a straight line then being scattered across the graph.
The last graph, which is marked with the blue dot is the correct one.
The last scatterplot (option D) has a correlation coefficient closest to r = -1.
What is correlation coefficient?The correlation coefficient describes how one variable moves in relation to another.A positive correlation coefficient indicates that the two move in the same direction.A negative correlation coefficient tells you that they instead move in opposite directions.A correlation coefficient of zero suggests no correlation at all.For given situation,
When the y variable tends to decrease as the x variable increases, we say there is a negative correlation between the variables.
i.e., it must have negative correlation coefficient.
If we observe the last scatterplot i.e., option (D), then it must have negative correlation coefficient.
Therefore, the correct answer is option (D)

The additional information that could be used to prove that ΔABC ≅ ΔPTQ using AAS or ASA are:
1. ∠B ≅ ∠P and BC ≅ PQ
2. ∠A ≅ ∠T and AC = TQ = 3.2cm
4. ∠A ≅ ∠T and BC ≅ PQ
Recall:
For two triangles to be congruent by AAS Congruence Theorem, they must have two pairs of congruent angles and a pair of non-included congruent side.For two triangles to be congruent by ASA Congruence Theorem, they must have two pairs of congruent angles and a pair of included congruent side.We are given:
∠C ≅ ∠Q
To prove that ΔABC ≅ ΔPTQ by ASA, the additional information needed are:
∠B ≅ ∠PBC ≅ PQAlternatively, the ASA can be used if the following additional information is given:
∠A ≅ ∠TAC = TQ = 3.2cmUsing the AAS Congruence Theorem, the additional information needed would be:
∠A ≅ ∠TBC ≅ PQIn summary, the additional information that could be used to prove that ΔABC ≅ ΔPTQ using AAS or ASA are:

Suppose v varies directly as g, and v = 36 when g = 4. Find v when g = 11. 101 99 124 112 Activate Windows Go to Settings to activate Windows. 3:14 PM
Answer:
v=99
Step-by-step explanation:
This is somewhat like a ratio problem. So, when v is 36, g is 4. We can simplify this. So, if we divided g by 4 we get one, and if we divide v by 4 we get 9. So, we have 1:9 ratio of g to v. If g is 11, then we multiply the 1 by 11 and the 9 by 11 also. Therefore, v is 99

17,18,19,20,21,22,23,24. 1.From the list of numbers write down a number that is a factor of 20. 2. From the list of numbers in the list, which is a multiple of both 3 and 7
Problem 1
Answer: 20--------------------------
Explanation:
The factors of 20 are 1,2,4,5,10,20
They are numbers that pair up to multiply to 20. For instance, 5*4 = 20. We only focus on whole numbers.
In the list given to us, we see that only 20 is a factor of 20. Something like 17 is not a factor of 20, and so on for the other values.
==========================================
Problem 2
Answer: 21--------------------------
Explanation:
List out the multiples of 3 to get {3, 6, 9, 12, 15, 18, 21, 24, 27, 30, ...}
The stuff in bold are values found in the original list.
Now list out the multiples of 7 to get {7, 14, 21, 28, 35, 42, ...}
We can see that only 21 is found in both lists of multiples we wrote out.
Note how 3*7 = 21, which is not a coincidence.

Answer:
20
Step-by-step explanation:
Total no of plants in a garden = 36
The ratio of tomato plants to cucumber plants to be 4:5.
Let tomato plants are 4x and cucumber plants is 5x.
ATQ,
4x+5x=36
9x = 36
x = 4
For cucumber plant, 5x = 5(4) = 20
So, there are 20 cucumber plants will be in Reggie's garden
