Answer:

Step-by-step explanation:
Let k represent the price in dollars at which Nita will buy the keyboard.
We have been given Nita wants to buy a new keyboard for her computer. She will buy the keyboard when it is on sale for under $50.
This means that Nita will buy the computer, when its price (k) is less than $50. We know that sign < represents less than.
We can represent our given information in an inequality as:

Therefore, our required inequality would be
.
Answer:
C
Step-by-step explanation:
For f(x) to be odd then f(- x) = - f(x)
determine whether
9 - 4(- x)² is equivalent to - (9 - 4x²) → C

Step-by-step explanation:
Ball is tossed 24 times
So the total number of outcomes (tosses) = N = 24
The ball lands in Blue section 3 times out of 24 tosses. So it becomes 3/24
The ball lands in Green section 5 times out of 24 tosses. So it becomes 5/24
The ball lands in Red section 12 times out of 24 tosses. So it becomes 12/24
The ball lands in Yellow section 4 times out of 24 tosses. So it becomes 4/24
Now we have to find how many times will the ball most likely land in the yellow section when it’s tossed 200 times. So the total number of outcomes here is N = 200. The favorable outcome here is that the ball lands in Yellow section. So we use the frequency table above for yellow section:
Yellow / Total tosses
4/24 = x/200
4*200 = 24x
800 = 24 x
24 x = 800
x = 800 / 24
x = 33.3
So ball most likely land in the yellow section 33 times when it’s tossed 200 times So it becomes 33/200 = 0.165 or 10.65% probability that ball will land in yellow section.
