Answer:
Mya wrote two expressions that are not equivalent
Step-by-step explanation:
45 +72 does not equal to 9(5+9)
9(5+9) = 45 + 81
Answer:
She can determine that while there is an association between the variables, there is no correlation, and she cannot determine causation.
Step-by-step explanation:
Since there is an arch shape to her graph, we know that as one variable changes, the other changes in the same manner. This means there is an association between the variables.
However, since the graph is not linear, there is no correlation between the variables. Since there is no correlation, we cannot determine causation.

Answer:
Since, the prime factors of 63 are 3, 7. Therefore, the product of prime factors = 3 × 7 = 21.

Answer:
35
Step-by-step explanation:
Given that:
Initial number of flip flop pairs = 100
After some sale:
3/5 of flip flops left are blue = 39
The number of flip flops sold :
Let number of flip flops sold = s
Initial number - number sold = number left
Number Sold = (100 - x)
3/5 of What is left = 39
Hence,
3/5 ( 100 - x) = 39
60 - 0.6x = 39
-0.6x = 39 - 60
-0.6x = - 21
x = 21 / 0.6
x = 35
Answer:
8.7 (nearest tenth)
Step-by-step explanation:
Applying pythagorean theorem, a² + b² = c²,
Where,
a = 5
b = the third side
c = hypotenuse = 10
Plug in the values
5² + b² = 10²
25 + b² = 100
Subtract 25 from each side
b² = 100 - 25
b² = 75
Take the square root of both sides
b = √75
b = 8.7 (nearest tenth)
