Answer:
Yes, it's enough information
Step-by-step explanation:
yes, there is enough information to determine the cost of 1 pack of pencils and 1 pack of pens
we just need an algebra of elimination and substition to find the coat of each. like this:
pencils = C
pen = N
2 C + 3 N = 8.25 (times by 2)
5 C + 2 N = 11.00 (times by 3)
------------------------- - (we eliminate the N)
4 C + 6 N = 16.50
15 C + 6 N = 33.00
------------------------- -
-11 C = - 16.5
C = (-16.5) : (-11) = $ 1.50
so the price of 1 pack of pencils is $ 1.50
now we use subtitution to find the price of 1 pack of pens
2 C + 3 N = 8.25
2 (1.50) + 3 N = 8.25
3.00 + 3 N = 8.25
3 N = 8.25 - 3.00
3 N = 5.25
N = 5.25 : 3 = $ 1.75
so the price of 1 pack of pencils is $ 1.75
Answer: The slope is the cost per muffin and the intercept of 3 is the delivery charge.
Step-by-step explanation:
I will assume that the graph has total cost in dollars for the y axis and number of muffins on the x axis. A slope of 2 means that y will increase by 2 for every 1 increase in x. That means that the price of a single muffin is $2.
The intercept of 3 at x = 0, means that there is an upfront (delivery) charge of $3. One muffin would cost $2 for the muffin plus $3 for the delivery, for a total of $5.
10 muffins would cost $20 for the muffins plus $3 for the delivery, for a total of $23.
Answer:
Lowering the level of significance, α increases the probability of making a Type II error, β.
Step-by-step explanation:
Lowering the level of significance, α increases the probability of making a Type II error, β.
This is because the region of acceptance becomes bigger, and it makes it less likely for one to reject a null hypothesis, when it is false, the type II error.
