Answer:
Mild correlation.
Step-by-step explanation:
Girls tend to have smaller feet and so smaller shoe sizes and they tend to score better at school.
No. You can’t add the two lower numbers up to make the bigger number making them not a triangle.
(3d x 6) + 1 = (9 x 4) + 2
-> 18d + 1 = 36 + 2
-> 18d = 38 - 1
-> 18d = 37
-> d = 37/18
-> d = 2.056
Answer:
$ 3199.0
Step-by-step explanation:
Let the number of shares of ABC = x
and XYZ = y
writing each as a linear equation
32 x + 23 y = 10100 equation 1
1.2 x + 1.4 y = 540
1.4 y = 540 - 1.2 x
y = ( 540 - 1.2 x) / 1.4
substitute for y in equation 1
32 x + 23( 540 - 1.2 x) / 1.4 = 10100
32 x + 8871.43 - 19.71 x = 10100
collect the like terms
32 x - 19.71 x = 10100 - 8871.43
12.29 x = 1228.57
x = 1228.57 / 12.29 = 99.97
the amount of money to be invested in ABC shares = 99.97 × $ 32 = $ 3199.0
Solving an equation uses the formulas
