The inequality that represents the possible combinations of candy bars and lollipops that he can buy is given by:
The total price can be no more than $28, hence:
Each candy bar costs $0.45 and each lollipop costs $0.25. x is the number of candy bars and y of lollipops. Hence, the total price is given by:
T = 0.45x + 0.25y.
Hence, the inequality that models the situation is:

Answer: Correct
Step-by-step explanation:
The conclusion is valid. Since and
, we know that ABCD is a parallelogram because it has two pairs of parallel sides. Also, since
, we know that ABCD is a parallelogram with a pair of consecutive congruent sides, making it a rhombus.

Step-by-step explanation:
Given that after a ham is cured it may be smoked to add flavor or to ensure it lasts longer.
Let X be the smoking time . Then X is N(mu, 8)
a) The sample is drawn at random
b) The sample represents the population
c) Sample size is sufficient to represent the population
b)For 99% conf interval z critical is taken since population std dev is given
Z critical = 2.58
Hence confi interval =
c) As sample sizes are large and samples are randomly drawn, we can be 99% confident that sample mean falls within this interval
d) If margin of error is only 2, then we must have
