$7.18 / 2 = $3.59 per pound
.........................................
so 1 lb = $3.59
2 lbs = 2* $3.59 = $7.18
3 lbs = 3 * $3.59 = $10.77....
Answer:
y = 28
Step-by-step explanation:
Given that y varies directly as x and inversely as z then the equation relating them is
y = 
← k is the constant of variation
To find k use the condition y = 4 when x = 2 and z = 7, then
4 = 
( multiply both sides by 7 )
28 = 2k ( divide both sides by 2 )
14 = k
y = 
← equation of variation
When x = 6 and z = 3 , then
y = 
= 14 × 2 = 28
Answer:
Strength and direction of the relationship.
Step-by-step explanation:
Given that A study finds a correlation coefficient of r = .32. This number gives you information about which of the following?
Group of answer choices Type of relationship and importance Statistical validity and external validity Statistical significance and effect size Strength and direction of the relationship.
We know that correlation coefficient represented by r is a measure of association between two variables. r can lie between -1 and 1. While negative correlation suggests inverse relationship positive a positive association.
0 correlation means the two variables are independent.
If nearer to 0, it represents weak correlation and nearer to 1 than 0 represents strong correlation.
Here r =0.32 a weak positive correlation
r represents
Strength and direction of the relationship.
Answer:
no
Step-by-step explanation:
because they have different gradients
Answer:
Nori would have 9/12 of a bag left.
Step-by-step explanation:
she had 2 2/12 and she used 1 5/12 so you subtract them and get 9/12
