Answer:

Step-by-step explanation:

which numbers are composite:49,35,32

which numbers are equal :2/3=4/6=6/9

your answer would be 4/6,6/9

explanation

(2/3)×2=4/6

therefore 4/6 is a multiple of 2/3

(2/3)×3=6/9

therefore 6/9 is a multiple

if we comprise 4/6 & 6/9 we get 2/3

Answer:

(d) WEAK NEGATIVE ASSOCIATION.

Step-by-step explanation:

Pearson correlation (r) is defined as a factor which measures the linear dependence between two variables (x and y). It's also known as a parametric correlation.

Here, r = -0.19

Now, as r is NEGATIVE.

⇒ As the value of x increases , value of y decreases.

⇒There is a  NEGATIVE ASSOCIATION.

Now as the value of r is between 0 and ( -1). So the factor of variation is very small.

Hence, it is WEAK NEGATIVE ASSOCIATION.

9 tenths - 3 tenths =
amm1812
9 tenths - 3 tenths = 6 tenths. this is true the same way that 9 minus 3 = 6. In reality the tenths make both numbers decimals, but in this case the "tenths" is just a classification of the number and it doesn't effect the answer.

Circumference + perimeter =38
x = circumference of circle
find r in terms of x
2\pir=x
r=\frac{x}{2 \pi }
Area=\pir^2
so..
A=\pi(\frac{x}{2 \pi })^2
=\pi(\frac{x^{2} }{4 \pi ^{2} })
=\frac{x^{2} }{4 \pi }

(38-x) is perimeter
then 
\frac{38-x}{4}
(\frac{38-x}{4})^2
\frac{x^{2} }{4 \pi } + (\frac{38-x}{4})^2
then you graph it and it equals
16.716 cm the circumference of the circle
