For the first one the answer is 2
Answer:
Part 1) The constant of proportionality is 
Part 2) The price of 6 bags of candy is 
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form
or 
In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin
step 1
Let
x ------> the number of bags of candy
y -----> the price
Observing the graph
For x=1
The value of y=6
so
Find the value of k (constant of proportionality)

substitute

The linear equation is equal to

step 2
Find the price of 6 bags of candy
For x=6
substitute in the equation and solve for y

Answer:
8/3 is the unit rate of change
for graph: second point on the line coordinates will be (3,8)
Answer:
a. 5.26
Step-by-step explanation:
As, the standard deviation of the distribution of the difference between mean is 0.76 so the t score will be simply calculated by dividing the difference of means by standard deviation of the distribution of the difference between mean as hypothesized difference is zero.
t score=Xbar A- Xbar B/Sd of difference of means
t score=55-51/0.76
t score=4/0.76=5.26
Answer:
You can use proportions by settling the ratio from the sample equal to the ratio from the population.
Explanation:
For Example is 3 out of 50 phones in a sample are defective, then an estimated 60 out of 1000 phones in a population are defective. this can be found by solving the proportion 3/50=x/1000 where x is the estimated number of defective phones in the population.
