Answer:
No
Step-by-step explanation:
y = 2x -1
Substitute the point into the equation
4 = 2(3) -1
4 = 6-1
4 =5
This is not a true statement so the point is not on the line
Answer:
y = 4.25x
Step-by-step explanation:
Cheddar cheese cost 4.25 per pound . This means the cost of cheddar cheese is 4.25 for every pound in weight. Assuming we put a currency to the value we can say 1 pound of cheddar cheese is equals to 4.25 dollars($4.25). Mathematically, it can be represented as
4.25 is the cost for 1 pound of Cheddar cheese
Let the cost of the equation be y as required from the question.
y = cost of the cheddar cheese
x is the weight value in pounds of the Cheddar cheese.
The equation can be best represented as
y = 4.25x
In the equation above if the amount in pounds is 3 pound . the value will be inputted for x and the cost will be gotten which is y.

I think 3 would be the answer if not I'm sorry
Answer:
These data do not provide evidence that the 8% value is inaccurate, this at the significance level of 5%.
Step-by-step explanation:
Let p be the true proportion of children nearsighted. We want to test the next hypothesis:
vs 
(two-tailed alternative)
We have a large sample size of n = 194 children. Therefore, the test statistic is given by
which is normally distributed.
The observed value is
.
The rejection region using a significance level of 0.05 is given by RR = {z | z < -1.96 or z > 1.96}. Because the observed value 1.4502 does not fall inside the rejection region, we fail to reject the null hypothesis.
