In the year 1900, the total number of metric tons of copper purchased in the world was 495,000. Each year since 1990,
the total number of metric tons of copper production has increased on average by 3.25%. Which function models the
total number of metric tons produced, y, for x years since 1990?
А
c(2) = 495.000,20.9675
cc() = 495, 000(1.0325)*
B.
C(2) = 495,000...1.0325
D
c(2) = 495,000(0.9675)

Is this quadratic?
(0, 6), (1, 12), (2, 20), (3, 30)

A local ice cream shop wants to see if they should promote a new swizzleberry swirl or creamsicle flavored drink. In order to determine which one to promote, they took a sample of 80 patrons and asked them to choose which they preferred. The one that is significantly preferred over the other (at a .05 level of significance) will be promoted. It is expected that an equal number of patrons will choose each flavor. Based on the observed frequencies given below, what is the decision for this test

Let’s say you want to play a new card game called Pokee. Every player is dealt 4 cards and everyone compares what hands they have to see who wins. Our job is to figure out what the hierarchy of the hands should be. Below is a list of several scoring hands that we wish to compare. For each hand, count how many hands of that type there are (include the expression you used to get that value) along with a simple explanation of how you got that expression. Assume a standard 52 card deck with 4 suits.
a) Presidential Flush (J, Q, K, Ace, all the same suit)
b) Straightish (4 consecutive cards)
c)Flushed (4 cards of the same suit)
d) House (Two pairs of different cards)

Select the correct answer. Which expression simplifies to 8x5?

Jeremy bought a $60 pair of sneakers on sale for 15% off. Then, he used a coupon that gave him an additional 10% off. Can Jeremy find the cost of the sneakers by adding the percents? Justify your answer:

-by finding 25% off of $60, and

-by finding 15% off of $60, and then subtracting 10% from that cost.


Use the drop-down menus to complete your explanation.

---------------------------------------------------------------------------------------

Jeremy cannot/ can find the cost by adding the percents.

.

25% off of $60 is equal to $45.00/35.00/25.00/45.90

.

15% off of $60, then subtracting 10% from that cost is equal to 35.00/25.00/38.25/45.90...

.

The two total costs are equal/not equal
