 1 4 0.13
 2 6 0.20
 3 5 0.17
 4 7 0.23
 5 3 0.10
 6 5 0.17
total 30 1.00

The best explanation of how to find the experimental probability of rolling a 3 is:
To find the experimental probability of rolling a three, write a ratio of the number of times three occurs to the total number of trials. Simplify if necessary.

5/30 = 1/6 or 0.166 or 16.6% or 17%.

Answer:

To find the experimental probability, compare the total number of times the event occurs to the total number of trials. Compare the frequency of rolling the number six (9) to the total number of trials (60) using a ratio, and then reduce.

HELP PLEASE!! Identify the solution set of the inequality using the given replacement set. x < –2; {–5, –2.6, –2, –0.8, 1, 1.

UNO [17]

X< -2 means that x must be smaller than -2, so something like -3, -4, -5, etc

The only solution set that fits this is A.

Karen is a software saleswoman. Her base salary is $2100, and she makes an additional $50 for every copy of English is Fun she s

Shalnov [3]

Karen has a base salary that is $2100 and does not depends on how many copies she sells.

Additional to the base salary, she gets $50 for each copy she sells, so we can write this additional salary as 50*N, being N the number of copies she sells.

Then, we can write the total pay P as:

$P=2100+50N$

Then, if N=22, we can calculate the total pay as:

$P(22)=2100+50\cdot22=2100+1100=3200$

Answer:

The equation relating P and N is P=2100+50N.

The total pay when she sells 22 copies is $3,200.
