I got 23, 18, and 25 for the first one idk it's not on there though. Did you get an answer at all? I could try to get it again maybe I did something wrong
Answer:
Step-by-step explanation:
It is given that a card is drawn one at a time from a well-shuffled deck of 52 cards.
Total repetitions of this experiment = 11
Number of kings in the experiment = 2
Let E is the event in which a king is drawn in the 11 trials. So
Therefore, the experimental probability P(E) is .
To determine the cost of the mail, we simply substitute the mass of the package to the given function. Mathematical functions are used to relate two variables, observing how changing one variable affects the other variable. For this case, the cost of a mail and the weight of the package are related by the function <span>y = 0.7x2 –2.5x + 3 where x represents the mass in units of pounds (lb) and y is the cost in units of dollars ($). We calculate cost as follows:
</span><span>y = 0.7x^2 –2.5x + 3
</span><span>y = 0.7(5)^2 –2.5(5)+ 3
y = 8 dollars
Therefore, the cost of mailing a 5 lb package would be 8 dollars.</span>
Answer:
(4,1)
Step-by-step explanation:
Using substitution you can determine that 2*4-7 is in fact equal to 1
The correct answer is C. This is because
10^-2 = 1/10^2 which is 0.01
